Answer:

Yes, it is a right triangle.

Step-by-step explanation:

A right triangle follows the rules of 3,4,5 side lengths, in which 5 is the hypotenuse, 3 is the shortest side, and 4 is the opposite side.

Plug it into the equation. The equation you will use is:

(shortest side)² + (longer side)² = (hypotenuse)²

(9)² + (40)² = (41)²

Simplify. First, solve the power:

(81) + (1600) = (1681)

Simplify. Combine like terms:

(81 + 1600) = 1681

1681 = 1681 (True)

Yes, these sides can be used to make a right triangle.

Ulleksa [173]

Answer:

Step-by-step explanation:

First, we convert:

ounces to cups
weeks to hours

Result of conversion:

91 fluid ounces = 11.375 cups (1 cup = 8 ounces)
2.5 weeks = 420 hours (1 week = 168 hours)

To get the rate, we must divide the number of cups by number of hours

11.375 cups / 420 hours = 0.027 cups per hour = 0.03 cups per hour (approximated)

Hope that helps!

The sum of two numbers is thirty. Three times the smaller is equal to two times the larger.

Ad libitum [116K]

X + y = 30
3x = 2y
y = 30 - x

3x = 2(30 - x)
3x = 60 - 2x
5x = 60
x = 12

12 + 18 = 30

Is 500 inches less than or greater than 40 feet?

sp2606 [1]

500 inches is greater than 40 feet because, every 12 inches is 1 foot. Since every 12 inches is 1 foot you have to divide. 500÷12=41.6667. Hope this helps!

Please help me. I am so stuck.<br>

Alexxx [7]

Answer:

Converges to -25.

Step-by-step explanation:

$\sum_{k=1}^{\infty} -5 \cdot (\frac{4}{5})^{k-1}$ converges since $r=\frac{4}{5}$ .

The sum is given by $\frac{a_1}{1-r}$ where $a_1$ is -5.

$\frac{-5}{1-\frac{4}{5}}=\frac{-5}{\frac{1}{5}}=-5(5)=-25$ .
