Answer:

13,92838827718412‬ft

Step-by-step explanation:

a² + b² = c²

a = 13ft

b = 5ft

169 + 25 = 194

c = √194

c = 13,92838827718412‬ft

What is the rate of change in y with respect to x in the function x + 5y = 10?

rosijanka [135]

Answer:

-1/5

Step-by-step explanation:

let's put the function in slope intercept form (y = mx + b).

x + 5y = 10

y = - (1/5)x + 2

when the function is in slope intercept form, (m) is the rate of change or the slope.

therefore, the rate of change -1/5

Y varies jointly as x and z, and y = 32 m, x = 6 m, and z = 8 m. what is the value of y when x = 5 m and z = 12 m?

Fynjy0 [20]

As x = 5 & z=12,

<span>2/3 = y /(xz) = y/(5*12) </span>

<span>= y/60 </span>

<span>so y / 60 = 2/3 </span>

<span>y = (2*60)/3 </span>

<span>= 40</span>

Find the simple interest earned in an account with $300 at 5% annual interest for 7 years.

Fiesta28 [93]

Option A

The simple interest earned is $ 105

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

Given that, $300 at 5% annual interest for 7 years

Therefore,

Principal = $ 300

Rate of interest = 5 %

Number of years = 7

<em><u>The simple interest is given by formula:</u></em>

$Simple\ Interest = \frac{p \times n \times r }{100}$

Where,

p is the principal

r is the rate of interest

n is the number of years

<em><u>Substituting the values in formula,</u></em>

$Simple\ Interest = \frac{300 \times 7 \times 5 }{100}\\\\Simple\ Interest = 3 \times 7 \times 5\\\\Simple\ Interest = 105$

Thus simple interest earned is $ 105
