When y= 234, x= 18. Find the value of x when y= 91. A. 12.75
B. 4.9
C. 7
D. 33.4
F. 13

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Hey! So first divide 234 by 18 to find a ratio. You would get 13:1. So apply this to y=91. 91/13 is 7.

Answer 2

Answer:

Final answer:

To find the value of x when y = 91, set up a proportion using the given values and cross-multiply. Divide both sides of the equation by the coefficient of x to solve for x. The value of x when y = 91 is 7.

Explanation:

To find the value of x when y = 91, we can use the concept of proportionality. We know that when y = 234, x = 18. We can set up a proportion by cross-multiplying:

(x / 18) = (91 / 234)

Cross-multiplying gives us:

234x = 91 * 18

Dividing both sides by 234 gives us the value of x:

x = (91 * 18) / 234

Simplifying the expression, we get:

x = 7

Therefore, the value of x when y = 91 is 7.

Answer:

Perimeter = 14 + 2sqrt(17)

Area =28

Step-by-step explanation:

FG = 8 counted

EH = 6 counted

using the pythagorean theorem

height = 4 and the base = 1 in the right triangle

HG^2 = 4^2 + 1 ^2

hg^2 = 16+1

hg^2= 17

hg= sqrt(17)

ef^2 = 4^2 + 1 ^2

ef^2 = 16+1

ef^2= 17

ef=sqrt(17)

Perimeter = EF+FG + GH+HE

sqrt(17)+ 8+ sqrt(17) + 6

14 + 2sqrt(17)

A =1/2 (b1+b2) * h

b1 =EH b2 = FG and h = 4 height that we used in the perimeter

= 1/2 (6+8) * 4

= 1/2 * 14*4

=28

Look at the picture.

$A=(1)/(2)(8+6)\cdot4=(1)/(2)(14)\cdot4=7\cdot4=28$
