Answer:

c = 29

Step-by-step explanation:

Alright, So from the numbers, we know each side is 7

So overall area is 49

And each triangle is 5(5 x 2/2)

And multiply that by 4 to get 20

49 - 20 is 29

Answer:  the length of c is √29

Step-by-step explanation:

The Pythagorean Theorem states that "The square on the hypotenuse is equal to the sum of the squares on the opposite sides."

The formula looks like c² = a² + b²

To apply that here, "c" is the hypotenuse of the right triangle that has "2" and "5" as the opposite sides. We can consider 2 as side a, and 5 as side b.

Square each of those numbers, then add them together.

2² means 2×2=4  and 5² is 5×5=25   4+25 = 29

Now we go into reverse to get the value of c.  We have c²=29

So we take the square root of 29  c=√29

That is an "irrational" number, meaning it is not a whole number or a fraction. So we can get an approximate value by using a calculator. (Nowadays! Back in the day, there was a nice long paper and pencil procedure. . .)

√29 is about 5.385164807....  and it keeps going. Just round it off!

(Some math teachers are fine with leaving the irrational roots as √something)

Apparently, the green answer box for this question needs √29

But it helps if you can associate some nearly rational value to make sense of it.

But you know the length of c should be about 5.39. It makes sense if you were to measure the sides with a ruler.

Answer:

-2.72

Step-by-step explanation:

-8.16 / 3 = -2.72

Extra:

3(-2.72) = -8.16

Answer: +/- \(\sqrt{A\)  = s

Step-by-step explanation:

A= S^2

then square root both sides

\(\sqrt A^2 = \sqrt{s ^2\)

+/- \(\sqrt{A\)  = s

Answer:

6/12 (50%)

Step-by-step explanation:

If you roll greater than 3 you have a 3/6 chance of it, if you then roll a number less than 4 you have another 3/6 chance of it, therefore it should be 50% or 6/12

Answer:

B

Step-by-step explanation:

34 x 1/2 = 17 (Line A'B')

28 x 1/2 = 14 (Angle A')

The length of A'B' and measure of angle A after the dilation are respectively: 15 & 28°.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

By Pythagoras theorem we can check, the given sides do not form a right angle triangle.

Now, let's apply the dilation to the given triangle ABC.

Since the dilation factor is 1/2, the length of each side of A'B'C' will be half of the corresponding side of ABC.

So, the length of AB is 30 and the length of A'B' is 1/2 of AB, which is 15.

To find the measure of angle A', we need to use the fact that corresponding angles in similar triangles are congruent. S

ince ABC and A'B'C' are similar triangles, angle A is corresponding to angle A'. We know that angle A is 28 degrees, so angle A' must also be 28 degrees.

Therefore, the answer is D. A'B' is 15 and mZA' is 28°.

Answer:

Step-by-step explanation: ok so first you need to circle all your variables x.

which are 2.4x+5x+3.1x adding those you get 10.5.

then circle your variables y which is 8.6y+6.5y+7y you get 22.1 then subtract those you get -11.6

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

Marc: 8 meters & 4 seconds

Prisha: 6 meters & 3 seconds

Step-by-step explanation:

Marc: If Marc travels 8 meters in 4 seconds it means that he has a speed of 2m/s

Prisha: If Prisha travels 6 meters in 3 seconds it means that she has a speed of 2m/s

To find speed we simply have to divide distance by time

The way that I figure out the answer was by trial and error. This is when we have to get random numbers and try them.

2 seemed a reasonable answer as it couldn't a number such as 5 as there is only 1 factor of 5 between 0 and 9. There are 4 factors of 2 between 0 and 9

Answer: Let length = 2x + 3

Let width = x

Area = 54 ft2

length × width = Area

x(2x + 3) = 54

2x2 + 3x = 54

2x2 + 3x - 54 = 0

(2x - 9)(x + 6) = 0

x = 9/2 and x = -6

x = 4.5 and x = -6

We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:

width = 4.5 ft

length = 2(4.5) + 3 = 9 + 3 = 12 ft

Answer:

C

Step-by-step explanation:

Parallel lines never touch so they cant be intersecting so C is the only possible answer

The statement "parallel lines always be the same distance apart" is true.

Parallel lines are two or more lines in a plane that are equidistant from each other at all points.

Parallel lines are lines that are always the same distance apart and never intersect. They are denoted with arrowheads pointing in the same direction. This means that no matter how far they are extended in either direction, they will never meet.

Option A is false. Parallel lines never intersect, so they cannot form any angles, let alone four right angles.

Option B is also false. Parallel lines can intersect in a special case known as hyperbolic geometry, but in Euclidean geometry (the geometry that we use in our everyday lives), parallel lines do not intersect at all.

Therefore, option C is the correct statement.

#SPJ3

Answer:

It is point c

Step-by-step explanation:

ok so the coordinates are always (x,y) so therefore if X is 0 then it stays in the middle of the graph and doesn't go anywhere. since Y is -3, y always goes down or up. so if it goes down then it is negative. up is always positive. same with x. X is always horizontal so if it moves right, it is positive and left (backwards) is negative. hope this helps and isn't confusing. *Also, since it's -3, then it goes down negative 3 units. *

Answer:

C

Step-by-step explanation:

In the coordinate (x,y), x refers to the place of point above the horizontal line while y represents the place of point in the side to its vertical lines.

Here, x is 0, that means it is lying on y line and y is -3, that means it's lying in 3rd quadrant. So, point C matches them completely. That's why the correct answer is C.

Answer:

He can only display box sets that are less tan 0.62 inches. So he can only display: \(\frac{1}{4} inch, 0.5 inch, \frac{3}{8} inch\) He can't display the box sets that measure 1 inch, and 1.5 inch.

Step-by-step explanation:

In order to resolve this problem, we should rewrite all the measures on decimal numbers to have an easier way to compare. To do so, we divide the numerator by the denominator.

\(\frac{1}{4} inch=1:4=0.25\\\\\frac{3}{8} inch=3:8=0.37\\\\\frac{5}{8} inch=3:8=0.62\)

He can only display box sets that are less tan 0.62 inches. So he can only display: \(\frac{1}{4} inch ,0.5 inch, \frac{3}{8} inch\). He can't display the box sets that measure 1 inch, and 1.5 inch.
