The hypotenuse of the triangle is 8.603487665. But if you’re rounding to the nearest tenth, the answer would be 8.6

Explanation: you use the square root button on the calculator and add 8.1+2.9 but make sure you square the numbers because you’re finding the hypotenuse. I attached a pic for you to see what I typed in the calculator:)

$5000 at 6% for 9 months what is the balance

Kay [80]

I think it's suppose to go

6% is .06 divided by 12 which is .005 times the number of months so in this case 9 so 5,000 times .005 times 9 which is 225 so 5,000 plus an interest of 225 adds up to 5,225

Emma uses turquoise beads to make bracelets to sell at an event. The total amount Emma earns, y, is proportional to the number

NNADVOKAT [17]

<h3>The equation represents the total amount Emma earns at the event is y = 10x</h3>

<em><u>Solution:</u></em>

Given that,

<em><u>The total amount Emma earns, y, is proportional to the number of bracelets, x, she sells</u></em>

$y \propto x\\\\y = kx -------- eqn\ 1$

Where,

y is the total amount Emma earns

x is the number of bracelets

k is the cost of each bracelet

<em><u>Emma earns $10 for each sold bracelet</u></em>

Therefore, k = 10

Thus, eqn 1 becomes,

<h3>y = 10x</h3>

Thus the equation represents the total amount Emma earns at the event is found

Find the volume of each figure

pshichka [43]

Answer:

See explanation

Step-by-step explanation:

1. The first figure shows triangular prism. The volume of the triangular prism is

$V=\text{Base area}\times \text{Height}$

The base of this triangular prism is the triangle with the base of 7 cm and height of $h$ cm (it is not seen).

The base area is

$\text{Base area}=\dfrac{1}{2}\times \text{Base}\times \text{Height}=\dfrac{1}{2}\times 7\times h=\dfrac{7h}{2}\ cm^2$

and the volume of the prism is

$V=\dfrac{7h}{2}\times 13=\dfrac{91h}{2}\ cm^3$

Just substitute the length of the height and calculate the volume.

2. The second figure shows square pyramid. The volume of the square pyramid is

$V=\dfrac{1}{3}\times \text{Base area}\times \text{Height}$

The base of this square pyramid is the square with the side length of 4 yd.

The base area is

$\text{Base area}= \text{Side Lenght}^2=4^2 =16\ yd^2$

and the volume of the pyramid is

$V=\dfrac{1}{3}\times 16\times 12=64\ yd^3$
