the corresponding side of the other triangle?
A. 10/12
B. 14
C. 21
D. 4 2/3

Answers

Answer 1
A. 2 parts is 7, so 7/2 is 3.5 = 1 part, then multiply by 3 to make the corresponding side which is 10.5 or 10 1/2

Please help (I will mark brainliest)!!!!!

Answers

We need to find the scale factor which so I will pick one side for both triangles

48/30= 1.6

1.6 is the scale factor

So now

25x1.6= 40

Therefore the answer is E) 40

Solve each problem. Round to the nearest tenth if necessary. Use 3.14 for π. What is the radius of a circle with a circumference of 15 cm? Show your work! I will be giving out brainliest!

Answers

Answer:

2.3

Step-by-step explanation:

First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)

Answers

g(6) = (1/3)(6) + 3 because the expression you stated for g(x) simply has one third as the coefficient, i.e. it's a linear function--if something else was intended, you would have to include parentheses to control the PEMDAS evaluation.

Therefore g(6) = 5
and consequently f(g(6)) = f(5) = 6(5) - 3 = 27

8th grade math, please help.

Answers

Answer:

x=72 degrees

Step-by-step explanation:

180-108=72

it is 180 because a straight angle is 180 degrees.

then you subtract 108, which is an alternate interior angle, to get 72, which is an alternate exterior angle.

Answer:

x=72

Step-by-step explanation:

Since the whole angle is 180 you have to do 180-108 which you get 72.

Then since x and 72 are vertical angles they have to be the same so x=72

each of equal sides of an isosceles triangle is 4cm greater than its height .If the base of triangle is 24 cm ,calculate the perimeter and the area of the triangle​

Answers

Answer:-

192 cm²

Step by step explanation :-

Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .

According to Pythagoras Theorem :-

=> base² + perpendicular ² = hypontenuse ²

=> 12² + x² = (x+4)²

=> 144 + x² = x² + 16 + 8x

=> 8x = 144-16

=> 8x = 128

=> x = 128/8

=> x = 16 cm .

Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.

= 1/2 * 16 cm * 24cm .

= 192 cm²

★ Hence the area of the triangle is 192 cm² .

Number 4!!What is the cost of 80cm of copper pipe at €2 a metre?

Answers

Answer:

$1.6

Step-by-step explanation:

We need to find the cost of 80 cm of copper pipe at $2 a metre.

Cost of 1 metre = $2

80 cm = 0.8 m

It means,

0.8 m = $2 × 0.8

= $1.6

So, the cost of 80 cm of copper pipe is equal to $1.6.

Change the X value of each of the points by -5, as this represents 5 units left.

Change the Y value of each of the points by +2, as this represents 2 units up.

For E:

X: 4 - 5 = -1

Y: -1 + 2 = 1

Coordinate: (-1,1)

It has to be b because it need up on -1,1
