Answer:

B

Step-by-step explanation:

In similar triangles corresponding sides are in same ratio

\dfrac{CV}{CE}=\dfrac{CU}{CD}\\\\\\\dfrac{CV}{54}=\dfrac{14}{98}\\\\CV=\dfrac{14}{98}*84\\\\CV = \dfrac{1}{7}*84\\\\CV = 12

Answer:

B) 12

Step-by-step explanation:

CD - 98

CE - 84

~

CU - 14

CV = 12

-

You set up a proportion: 98/84 = 14/x

x=12

Question #18 <br> A.) g(x)=-4x+12<br> B.)g(x)=-3x+4<br> C.) g(x)=-1/3x+4/3<br> D.)g(x)=-3x+12
wlad13 [49]

Answer: B) g(x) = -3x + 4

<u>Step-by-step explanation:</u>

Given f(x) = a(x - h) + k

  • a: represents the vertical stretch
  • h: represents the horizontal shift to the left (-) or right (+)
  • k: represents the vertical shift up (+) or down (-)

You are given f(x) = -x with a vertical stretch of 3 and a vertical shift up 4

→ a = 3, k = 4

resulting in: g(x) = -3x + 4

Angle A and Angle B are supplementary, mZA = (6x + 72) and mZB = (2x + 28)". Find x, the
Alexeev081 [22]

Answer:

x = 10

m<A = 132 degrees

m<B = 48 degrees

Step-by-step explanation:

Supplementary = angles that make up 180 degrees

We know <A and <B are supplemntary, so 2x+28+6x+72 = 180.

8x + 100 = 180

8x = 80

x = 10

I input 10 into the equations to solve for the measures of the angles

the students of a bayside middle school are going on a field trip . 15 students fit in a van and 3 students will be traveling in
Katen [24]

Answer:

The algebraic expression for this problem is T=15x+3y.

Step-by-step explanation:

Given:

15 students fit in a van and 3 students will be traveling in a car.

So we can say that;

Number of students travelling by van = 15

Number of students travelling by car = 3

Now Let the number of vans be 'x'.

also Let the number of cars be 'y'.

Let the Total number of students bayside middle school be 'T'.

Solution:

now we can say that;

Total number of students going on field trip is equal to sum of Number of students travelling by van multiplied by the number of vans and Number of students travelling by car multiplied by the number of cars.

framing in equation form we get;

T=15x+3y

Hence, The algebraic expression for this problem is T=15x+3y.

Answer: 25.12 ft

To find the circumference of a circle, multiply the diameter with π (pi)

Formula: 2πr (2 × radius) (π = 3.14)

In the problem...

-----------------------------------------------------------------------------------------------------------------

We can multiply 3.14 by 8 to get the circumference.

3.14 × 8 = 25.12

Hence, 25.12 is the answer, but we can do it another way.

Let me know if you have any questions.

~ Lily, from Brainly.

<em>Note to asker: Hi there, make sure to write down these formulas!</em>

<em />

<em>Circumference: 2πr</em>

<em />

<em>Area: πr²</em>

<em />

<em>Radius: </em>\frac{diameter}{2}<em />

<em />

<em>Diameter: radius × 2</em>
