Jlenok [28]3 years ago
8 0

Answer:

number of dimes is 8

number of quarters is 15

Step-by-step explanation:

let 'd' = number of dimes

let 'd+7' = number of quarters

.10d + .25(d + 7) = 4.55

.10d + .25d + 1.75 = 4.55

.35d = 2.80

d = 8

q = 7 + 8

Write the equation below in slope-intercept form. <br><br> x - y = 2
Arte-miy333 [17]

slope intercept form

y=mx+b

x-y =2

we need to subtract x from each side

x-y-x = -x +2

-y = -x+2

multiply each side by -1

-1*-y = -1(-x+2)

y = x -2

the slope intercept form is

y = x-2

what is the slope of a 5-foot high platform that begins at ground level 10 feet from the base of the platform?​
Sladkaya [172]

Answer:

11.2 feet

Step-by-step explanation:

Given: Height of platform (Opposite)= 5 foot

            Distance of slope from the base of platform (adjacent)= 10 feet

Picture drawn to show the measurement.

Lets find the length of slope.

Using the Pythagorean theoram.

hypotenous^{2} = opposite^{2} + adjacent^{2}

Subtituting the value in the formula.

hypotenous^{2} = 5^{2} + 10^{2}

⇒ hypotenous^{2} = 25 + 100

⇒ hypotenous^{2} = 125

Putting square root on both side

We know, √a²= a

⇒ hypotenous = \sqrt{125}

∴ hypotenous= 11.18 \approx 11.2 \ feet

Hence, the slope is 11.2 feet
