Given the picture, what is the length of AC? A) 4.5 B) 5 C) 7.5 D) 8

drek231 [11]

we know that

triangles BCD and ACE are similar

so, their ratios of sides must be equal

Calculation of y:

$\frac{BC}{AC}=\frac{CD}{CE}$

we can see that

AC=AB+BC

AC=y+3

CE=CD+DE

CE=4+6

CE=10

now, we can plug values

$\frac{3}{y+3}=\frac{4}{10}$

now, we can solve for y

$3*10=4*(y+3)$

$30=4y+12$

$30-12=4y+12-12$

$18=4y$

$y=4.5$

Calculation of AC:

we know that

AC=y+3

we can plug y

and we get

$AC=4.5+3$

$AC=7.5$ ...................Answer

3 A Gas station A charges $3.50 per gallon of gas plus 58 for a car wash. Gas station B charges $3.25 per gallon of gas plus S10

Hoochie [10]

9514 1404 393

Answer:

8 gallons

Step-by-step explanation:

The $2 difference in the price of a car wash is made up by the gas purchase at the rate of $0.25 per gallon. So, it takes ...

$2/($0.25/gal) = 8 gal

to make the costs the same.

The customer must purchase 8 gallons for the total cost to be the same at both gas stations.

___

3.50g +8 = 3.25g +10 . . . . costs at each station for g gallons of gas + wash

0.25g = 2 . . . . . . . . . subtract 3.25g+8 from both sides

g = 2/.25 = 8 . . . . . . the way we did it above

The SHS step team is selling shs spirit t-shirts to raise money. The orange/black shirt sells for $15 and the black/white shirt

IRINA_888 [86]

Answer:

Option A)

$15x + 10y \geq 1000$

Step-by-step explanation:

We are given the following in the question:

Cost of orange/black shirt = $15

Cost of black/white shirt = $10

Amount of money to be raised is atleast $1000.

Let x be the amount of orange/black shirt and y be the amount of black/white shirt.

Thus, we can write the inequality:

$15x + 10y \geq 1000$

That is the total cost of orange/black shirt and black/white shirt should be greater than or equal to $1000.

Thus, the correct answer is

Option A)

$15x + 10y \geq 1000$
