Answer:

The equation relating S to W is:

S = 750 + 30W

where S is the total amount of money in the savings account (in dollars) and W is the number of weeks Debra has been adding money.

To find the total amount of money in the savings account after 16 weeks, we substitute W = 16 into the equation:

S = 750 + 30(16) = 750 + 480 = 1230

Therefore, the total amount of money in the savings account after 16 weeks is $1230

Answer:

$2.15

Step-by-step explanation:

Let mango be m

Let avocado be a

10m + 12a = 23

5m + 4a = 10

Let's get rid of the mangos in the second equation

       10m + 12a = 23

-2 x (5m + 4a = 10)

Now we get:

10m + 12a =23

-10m -8a = -20

Add both the equations and we get:

4a = 3

a = $0.75

since we know that one avocado is for $0.75, we can use this value to find the cost of one mango.

5m + 4a = 10

5m + 4(0.75) = 10

5m + 3 = 10

5m = 7

m = 1.4

So, we now know that a mango cost $1.4

To find the cost of one mango and one avocado:

a + m = 0.75 + 1.4 = 2.15

Therefore, the cost of one mango and one avocado is $2.15

The required cost of one mango is 1.4 and cost of one avocado is 0.75.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

Cost of ten mangos and twelve avocados is $23,

And cost of five mangos and four avocados is $10.

Let cost of mangoes be represented as M and cost of avocados be represented as A,

The equation can be written as,

10 M + 12 A = 23          (1)

5 M + 4 A = 10           (2)

By solving equation (1) and (2),

M = 7/5 = 1.4

N = 3/4 = 0.75

The cost of one mango is 1.4 and cost of one avocado is 0.75.

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Step-by-step explanation:

If you divide 2,35 by 12 you get 0.1958333333, which rounds to 0.

Answer:

0

Step-by-step explanation:

2.35 / 12 = 0.1958333...

2.35 = 47 / 20

47 / 20 ÷ 12 / 1

47 / 20 x 1 / 12 = 47 / 240

47 / 240 = 0.1958333....

0.1958333... rounded to the nearest whole number is ZERO. Because 1 is smaller than 4, which means that you would not round up.

Answer:

a. m<A = 35°

b. m<CBD = 61°

c. m AD is  sin55 = AD/40     AD = 32.77

d. m BC is sin 29 = 22.94/BC   BC = 47.32

e. m CD is tan 29 = 22.94/CD    CD = 41.38

f. m BD is cos 55 = BD/40    BD = 22.94

Step-by-step explanation:

The solution is,

a. m<A = 35°

b. m<CBD = 61°

c. m AD is  sin55 = AD/40     AD = 32.77

d. m BC is sin 29 = 22.94/BC   BC = 47.32

e. m CD is tan 29 = 22.94/CD    CD = 41.38

f. m BD is cos 55 = BD/40    BD = 22.94

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

from the given figure, we get,

a) ∠D = 90

i.e.  ∠A= 90 - 55 = 35

b)  similarly,

∠CBD = 90-29

          =61

c) m AD is  sin55 = AD/40

i.e.  AD = 32.77

d) m BC is sin 29 = 22.94/BC  

i.e.  BC = 47.32

e)  m CD is tan 29 = 22.94/CD    

   i.e. CD = 41.38

f) m BD is cos 55 = BD/40  

  i.e. BD = 22.94

#SPJ2

Answer:

The answer is D.

Step-by-step explanation:

y = mx + b

C = 5/9 (F - 32)

C = 5/9F - 5/9 (32)

Option (D) is correct.

1.The total of two sides is: $6 + 8 = 14$.

2.The missing side has a length of 4.

3.All three inequalities are true, so these side lengths do form a valid triangle.

4. It is not possible to have side lengths.

1. To find the total of two sides of the triangle shelf, we simply add the two given side measurements together.

2. $Perimeter = a + b + c$ where a, b, and c are the lengths of the three sides of the triangle. We are given that the perimeter measures 18, and we know that 6 and 8 are two of the sides, so we can substitute these values into the formula to solve for c:

$18 = 6 + 8 + c$

$18 - 14 = c$

$4 = c$

3. If we know that  $a$ = 3, $b$ = 5, and $c$ = 8, we can check if these side lengths form a valid triangle by using the triangle inequality theorem, Therefore, we need to check if:

$a + b > c$

$b + c > a$

$a + c > b$

Substituting in the given values, we get:

$3 + 5 > 8$ (True)

$5 + 8 > 3$ (True)

$3 + 8 > 5$ (True)

4. of $a$ = 2, $b$ = 4, and $c$ = 7 for a triangle. The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side. If we apply this to the given values, we get:

$a + b > c$

$2 + 4 > 7$ (False)

Step-by-step explanation:

V = (4/3)*pi*(r^3)

pi = 3.14, r = 4.5

so V = (4/3)(3.14)(4.5^3) which is choice B

use calculator to solve: V = 381.51 which is choice C

add 5 to both sides and u get the equation 14x<-1 then divide both sides by 14 to get x alone. that leaves you with x< -1/14 wich is then less than 4

Answer:

Step-by-step explanation:Yikes. Just so we’re all clear—this is not a real SAT question.

So far, Adam’s record is 6 wins/30 games. If he plays x more games, his record will be:

image

You find the minimum x such that the fraction is greater than ½, which would mean he won more than ½ of his games.

Let’s do some math!

image

So if he plays 54 more games, and wins 2/3 of them, he’ll have the same number of wins as losses. Check on that to make sure: He’ll have played 30 + 54 = 84 games, and won 6 + (2/3)54 = 42 of them. Yep, that works.

Now here is where it gets tricky (and why this question is not SAT-caliber). Remember that he’s losing 1/3 of his games. If his 52nd, 53rd, and 54th additional games were win, win, loss, then he would have had, very briefly, a winning record after his 53rd additional game.

His 55th additional game is another chance at a winning record. If he loses that game, then he’ll win the next two, and have a winning record for sure by the 57th additional game. From there, if he continues winning 2/3 of his games, he’ll have a winning record forever.
