First find the value of h, or the height using the pythagorean theorem.

13^2=15^2+h^2
289=225+h^2
h^2=64
h=8

Then use the formula bh/2 to find area of the triangle.

10*8/2=40

Final answer: A

Please help me struggling

Liula [17]

Answer:

Step-by-step explanation:

find the composition of g(x)=x−1 and h(x)= $\sqrt{x}$

hence we will get,

(g∘h)(x)=g(h(x))= g(x−1)= f(√x)= -1+√x = √x -1

Now to find f(g(h(x))),

f(x)=x4+6 and g(h(x))=√x -1

hence , putt g(h(x)) in f(x) ,

f(g(h(x)))= $(\sqrt{x}-1)^{4}$ +6 -

When Joycelyn goes to work, she drives at an average speed of 65 miles per hour. It takes about 1 hour and 30 minutes for Joycel

insens350 [35]

Jocelyn has to spend $13.46 on gas.

To find this, you first have to determine the number of miles she drives. You can find this by multiplying the speed by the travel time.

65 miles per hour * 1.5 hours = 97.5 miles.

Now that he have the amount of miles she drives, we can find the amount of gas she spends. In order to do that we'll divide the distance by the rate.

97.5 miles / 25 miles per gallon of gas = 3.9 gallons

Now we can determine the cost by multiplying the amount of gallons by the price.

3.9 gallons * $3.45 per gallon = $13.46

A mango weighs 36 ounces. The total weight of 3 magoes and 1 apple is the same as the weight of 5 apples. How much does 1 apple

Vadim26 [7]

Data:

M (mango)
A (apple)

We have:
1M = 36 ounces
3M + 1A = 5A

Replace and solving:

$3M + 1A = 5A$
$
3.(36) + 1A = 5A$
$108 + 1A = 5A$
$108 = 5A - 1A$
$108 = 4A$
$4A = 108$
$A = \frac{108}{4}$
$\boxed{A = 27}$

Answer:
Aple weigh 27 ounces
