Answer:

4.5 ft

Step-by-step explanation:

Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,

18/x = 8/2

Let's solve for x as required.

We have,

18/x = 8/2

=>Cross multiply:

18 × 2 = 8 × x

36 = 8x

=>Divide both sides by 8

36/8 = x

4.5 = x

x = 4.5 ft

The first option is our answer = 4.5 ft

A)R=0.65log(0.39E)+1.45

7.5=0.65log(0.39E)+1.45

B)6.05=0.65log(0.39E)   Subtracted 1.45 from~ both~ sides~ of~ equation.

9.31=log(0.39E)          Divided each side by 0.65.  



C) 9.31=log(0.39E)

10^(9.31)=0.39E

E=5.24*10^9 kilowatt hours

What is the equation of this line in standard form? 8x−7y=−25 8x−9y=23 8x−9y=−23 9x−8y=23 Number graph ranging from negative fiv
Gnoma [55]

Answer:

The equation of line is:

8x-9y=-23

Step-by-step explanation:

We are given that a graph is  a that passes through two points:

(-4,-1) and (\dfrac{1}{2},3)

We know that the equation of line passing through two points:

(a,b) and (c,d) is given by:

y-b=\dfrac{d-b}{b-a}\times (x-a)

Here we have:

(a,b)=(-4,-1) and (c,d)=(\dfrac{1}{2},3)

Hence, the equation of line is:

y-(-1)=\dfrac{3-(-1)}{\dfrac{1}{2}-(-4)}\times (x-(-4))\\\\y+1=\dfrac{3+1}{\dfrac{1}{2}+4}\times (x+4)\\\\y+1=\dfrac{4}{\dfrac{9}{2}}\times (x+4)\\\\y+1=\dfrac{4\times 2}{9}\times (x+4)\\\\y+1=\dfrac{8}{9}\times (x+4)\\\\9\times (y+1)=8\times (x+4)\\\\9y+9=8x+8\times 4\\\\9y+9=8x+32\\\\8x-9y=9-32\\\\8x-9y=-23

Hence the equation of line is:

8x-9y=-23

Kasey buys a shirt for 12.50 plus 6% sales tax. Sue buys a shirt for 10.00 plus 6%
zaharov [31]

Answer:

Kasey paid: $13.50

Sue paid:$10.60

Togethee they paid: $24.10

Step-by-step explanation:

Convert the sales tax percentage to a decimal by moving the decimal point two places to the left or you can divide it by 100.

This should give you .06

Multiply .06 with the original cost before sales tax.

Add this amount to the original cost to get your answer
