Step-by-step explanation:

\(4 (\frac{1}{2}x - 3 ) = 8\)

4 came from the number of people, Donavon, and 3 friends; 1 + 3 = 4

\(\frac{1}{2}\) came from the amount they spent on rides; They each spent \(\frac{1}{2}\) their money on rides

(-3) came from the amount they spent on food, Then they each spend $3 on food.

8 came from the total amount they had left; Donavon and his three friends have a total of $8 remaining.

4 (  \(\frac{1}{2}\)x - 3 ) = 8

Distribute;

4 (  \(\frac{1}{2}\)x - 3 ) = 8

2x - 12 = 8

Inverse operations;

2x - 12= 8

Mohammed had $5290 at the end of the month

What is addition and subtraction of integers?

At first it is important to know about integers

Integers are those numbers which has no fractional part. Integer can be positive, negative and zero is also an integer.

Suppose there are many integers, and we need to find the sum total of all those integers, then the operation used in this case is called addition.

To find how big or small one integer is from the other, then the operation used is called subtraction of integers.

Here we will use addition and subtraction of integers

Bank balance of Mohammed = $8376

Amount of money taken out by Mohammed next month to buy a car = $4595

Amount of money needed to buy new tires for his car = $1200

Amount of salary received by Mohammed next day = $2709

Amount of money Mohammed had at the end of the month =

$(8376 - 4595 - 1200 + 2709)

= $5290

The disadvantage of a certificate of deposit is you will pay a penalty if you withdraw your money too soon.

CDs, sometimes referred to as certificates of deposit, are bank deposit instruments that retain your money for a specific amount of time. The annual percentage yield, or APY, that the bank offers in return makes CDs a secure and dependable method to grow your money.

A CD's owner cannot access their funds as quickly as they may in a conventional savings account.

A penalty must be paid in order to remove funds from a CD before the term has ended.

This fine may take the shape of either a principal penalty or a lost interest penalty.

The owner will pay a penalty if you withdraw your money too soon.

Answer:

B only

Step-by-step explanation:

Triangles A and C are similar, but not congruent to each other. Similar triangles have proportional sides and congruent angles, while congruent triangles have congruent sides and congruent angles.

Therefore, only B is correct

The question is asking for pairs of congruent triangles but lacks key information needed to accurately answer this, such as lengths or angles. Congruent triangles are identified in geometry based on either side-lengths or angles.

The question is about congruent triangles, which in mathematics means triangles that have the same size and shape. But to accurately answer which pairs show two congruent triangles, we need more information. The options provided include 'A', 'B', and 'C' but without knowing more about these elements (for example their lengths or angles), it is impossible to determine which are congruent. Congruent triangles are identified in geometry based on either side lengths (SSS: Side-Side-Side, SAS: Side-Angle-Side, ASA: Angle-Side-Angle) or angles (AAS: Angle-Angle-Side, HL: Hypotenuse-Leg for right triangles). Without this vital information, we cannot definitively answer the question. Be sure to verify all the properties required to prove two triangles congruent.

Answer:

In explanation

Step-by-step explanation:

So, let's solve for y in both of these equations

3y + 2x = 8

3y = 2x+8

y = 2/3x+8/3

-3x - 2y = 6

-2y = 3x + 6

y = -3/2x-3

The lines are perpendicular, since their slopes are the negative reciprocal of each other.

Negative reciprocal =>     -1/n

The sum of the equations demonstrates this relationship, with 0x + 0y = 14

Spotify charges $0.98 for individual song and $10 for entire album

According to the question,

Spotify charges "x" dollars for individual songs and "y" for entire album

Also, Person A pays $14.9 to download 5 individual songs and 1 album

Which can be written as

=> 5x + y = 14.9 --------------(1)

Person B pays $22.95 to download 3 individual songs and 2 albums

=> 3x + 2y = 22.95 ---------(2)

Solving these two linear equations by elimination method

Multiplying equation (1) by 2

=> 10x + 2y = 29.8

Now, subtracting these equation

10x + 2y - 3x - 2y = 29.8 - 22.95

=> 7x = 6.85

=> x = 0.98

Replacing value of x in equation (1),

=> 5(0.98) + y = 14.9

=> 4.9 + y = 14.9

=> y = 10

Hence , Spotify charges $0.98 for individual song and $10 for entire album

Answer:

Average time per day = 1.2 hours per day
Average time per day = 72 minutes per day

Step-by-step explanation:

To find Clarence's average time per day, we need to divide the total time he takes to walk the 15.5 miles by the number of days he walks, which is five.

Let's calculate his average time per day:

Average time per day = Total time / Number of days

Since Clarence takes a total of 6 hours to walk the 15.5 miles, we'll divide 6 by 5 to find his average time per day:

Average time per day = 6 hours / 5

Average time per day = 1.2 hours per day

To convert hours to minutes, we'll multiply the average time per day by 60:

Average time per day = 1.2 hours * 60 minutes

Average time per day = 72 minutes per day

Therefore, Clarence's average time per day is 72 minutes.

\(\large \boxed{ \sf Height= 117.78 \ m }\)

Step-by-step explanation:

We need to find out the height of the skyscraper to thr nearest hundred of metre .

D I A G R A M : -

\(\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\put(0,0){\line(1,0){4}}\put(0,0.001){\line(0,1){1.5}}\put(0,1.5){\line(2,1){4}}\put(4,0){\line(0,1){3.5}}\put(0,1.501){\line(1,0){4}}\multiput(-1,0.75)(5.1,0){2}{$\sf 1.75 m $}\multiput(2,-0.75)(0,2.5){2}{$\sf 337 m $}\put(4.5,2.2){$\sf x $}\qbezier(0.7,1.5)(0.7,1.7)(0.5,1.75)\put(1,1.67){$\sf 19^\circ $}\put(5,-1.5){$\textcopyright \bf TonyStark $}\put(4, - .5){$\sf C $} \put(4,3.7){$\sf A $} \put(4.1,1.5){$\sf B $} \put( - .5,1.5){$\sf D $} \end{picture} \)

Here we can make use of trigonometric ratios to find out the value of firstly AB . In a right angled triangle, tangent is defined as the ratio of perpendicular and base. With respect to angle 19° , the perpendicular is "x" and the base is 337m.

Now in ∆ABD , we have ;

\(:\implies\sf tan\theta =\dfrac{AB}{BD}\\\)

\(:\implies\sf tan 19^\circ =\dfrac{ x}{337\ m} \\\)

\(:\implies\sf 0.3443=\dfrac{x}{337m} \\\)

\(:\implies\sf x = 337m \times 0.3443 \\\)

\(:\implies\sf \pink{ x =\frak{ 116.03 \ m }} \\\)

Now the total height of the skyscraper will be the sum of BC and AB , therefore;

\(:\implies\sf height_{skyscraper}= AB + BC \\\)

here ,

\(:\implies\sf Height_{skyscraper}= (116.03 + 1.75) m\\\)

\(:\implies\sf \underline{\underline{\boxed{ \sf Height_{skyscraper}= \frak{117.78\ m }}}} \\\)

Hence the height of the skyscraper is 117.78 m .

Answer:

The height of the skyscraper is 117.79 m to the nearest hundredth.

Step-by-step explanation:

If a person stands at a point and looks up at an object, the angle between their horizontal line of sight and the object is called the angle of elevation.

To find the height of the building, model as a right triangle and solve using the tangent trigonometric ratio. (See the attached diagram).

Tan trigonometric ratio

\(\tan \theta=\sf \dfrac{O}{A}\)

where:

Given information:

The line of sight is 1.75 m above ground level.  Therefore, the height of the skyscraper (the side opposite the angle of elevation) is (y + 1.75) m.

To find y, substitute θ = 19°, O = y and A = 337 into the tan ratio:

\(\implies \tan 19^{\circ}=\dfrac{y}{337}\)

\(\implies y=337 \tan 19^{\circ}\)

\(\implies y=116.038405...\)

To calculate the height of the skyscraper, add the found value of y to 1.75 m:

\(\begin{aligned}\implies \sf Height\;of\;skyscraper&=y+1.75\\&=116.038405... + 1.75\\&= 117.78840...\\&=117.79\; \sf m\;(nearest\;hundredth)\end{aligned}\)

Therefore, the height of the skyscraper is 117.79 m to the nearest hundredth.

Midpoints of two coordinates is expressed using the formula;

M(X, Y) = (x2+x1/2, y2+y1/2)

Given the coordinates  c(5,3) and d(-3,-6)

x1 = 5, y1 = 3, x2 = -3 and y2 = -6

X = x1+x2/2

X = 5+(-3)/3

X = 5-3/2

X = 2/2

X = 1

Also;

Y = y1+y2/2

Y = 3+(-6)/2

Y = 3-6/2

Y = -3/2

Y = -1.5

\(R_A_y+R_B_y=200+200+80+80R_A_y+R_B_y=560-----(1)\)

Take moments about point B and about the z-axis:

\(R_A_y*1.4=2*100*0.7+2*80*0.4\\\\R_A_y=245.71\)

Substitute the above value in equation (1).

\(245.71+R_B_y=560\\\\R_B_y=314.29N\)

Resolve the forces along the z-direction.

\(R_A_z+R_B_z=385+385R_A_z+R_B_z=770-----(2)\)

Take moments about point B and about the y-axis:

\(R_A_z*1.4=2*385*1.1\\\\R_A_z=605N\)

Substitute the above value in equation (2).

\(605+R_B_z=770\\\\R_B_z=165N\)

a) The resultant normal force at point D along the x-direction is

\(F_D_x=0\)  

b) The resultant shear force at point D along the y-direction is

\(F_D_y-R_B_y+2*80=0\\\\F_D_y-314.29+160=0\\F_D_y=154.29N\)

∠N = 180 - 90 - 33 = 57

∠N = 1/2 arc LM => LM = 2 ∠N = 2 x 57 = 114

11. ∠F = 1/2 arc HG => arc HG = 2 x ∠F = 2 x 94 = 188

12. ∠D 1/2 arc CE (which is semicircle) = 1/2 (180) = 90

∠E = 1/2 arc CD = 80/2 = 40

∠C = 180 - 90 - 40 = 50

Answer:

  10) 114°

  11) 45°

  12) 50°

Step-by-step explanation:

You want the angles or arcs shown in the figures with inscribed angles and triangles.

The measure of an inscribed angle is half the measure of the arc it subtends. Conversely, the the measure of the subtended arc is twice the measure of the inscribed angle.

The measure of the arcs of a circle is 360°. The measure of the arc of a semicircle is 180°.

An angle that is inscribed in a semicircle has a measure of 180°/2 = 90°.

Arc LMN is 180°. Arc MN is twice 33°, so ...

  arc LM = 180° -2(33°) = 114°

Note that arc LM is also double the inscribed angle MNL, which is the complement of 33°.

Long arc HG is double the measure of the 94° inscribed angle. The remaining unknown arc is the difference between 360° and the two known arcs:

  arc HF = 360° -arc HG -arc GF

  arc HF = 360° -2(94°) -127° = 45°

Arc CDE is a semicircle, so is 180°. Arc DE is the difference between that and arc CD:

  arc DE = 180° -arc CD = 180° -80° = 100°

Inscribed angle C is half this measure:

  angle C = (100°)/2 = 50°

Perimeter of quadrilateral is 26.39 unit.

Distance between two points with coordinates (x₁ , y₁)  and (x₂ , y₂). is given by

D = √[(x₁ - x₂)² + (y₁ - y₂)²]

This formula is derived from the Pythagoras Theorem, as the points form a right triangle in plane, with the hypotenuse representing the distance between them.

Given,

Quadrilateral ABCD

A(-3,2)

D(0,-6)

B(6,-2)

C(3,-6)

Perimeter = distance between A and B + distance between B and C + distance between C and D + distance between D and A

Perimeter =

√[(-3 -6)² + (2 - -2)²] + √[(6 - 3)² + (-2 - -6)²] +

√[(3 - 0)² + (-6 - -6)²] + √[(0 - -3)² + (-6 - 2)²]

Perimeter = √[(-9)² + (4)²] + √[(3)² + (4)²] + √[(3)² + (0)²] + √[(3)² + (-8)²]

Perimeter = √[81 + 16] + √[9 + 16] + √[9 - 0] + √[9 + 64]

Perimeter = √[97] + √[25] + √9 + √[73]

Perimeter = 9.85 + 5 + 3 + 8.54

Perimeter = 26.39 unit

Hence, 26.39 unit is the perimeter of quadrilateral ABCD.
