Karen spends $450 on monthly bills. Of this total amount, 12% is for phone service, 1/10 is for internet service, and 2/9 is for

finlep [7]

12%= 0.12 = 12/100 = 108/900
1/10 = 90/900
2/9 = 200/900

108/900 + 90/900 + 200/900 = 398/900 used

900- 398 = 502

502/900 = 251/ 450

251/450 × 450 = 251

Karen has $251 for food

Help anyone can help me do this question 3,I will mark brainlest.

malfutka [58]

Answer:

see explanation

Step-by-step explanation:

Calculate the slopes between pairs of the 3 points using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 9, 3) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-3}{-3-(-9)}$ = $\frac{6}{-3+9}$ = $\frac{6}{6}$ = 1

Repeat with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-1}{-3-5}$ = $\frac{8}{-8}$ = - 1

If lines are perpendicular then the product of their slopes = - 1 , then

1 × - 1 = -1

Thus there is a right angle between the 2 lines

Then triangle is right- angled

What is 1/7 divided by 252 ?

miskamm [114]

Answer:

In decimal form: $0.00056689342$ (If wanted to round to nearest thousandth, $0.001$ )

In fraction form: $\frac{1}{1764}$ or $\frac{28344671}{50000000000}$

Step-by-step explanation:

$\frac{1}{7}\div \:252=\frac{1}{1764}$

$\mathrm{Convert\:element\:to\:fraction}:\quad \:252=\frac{252}{1}\\=\frac{1}{7}\div \frac{252}{1}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}\\=\frac{1}{7}\times \frac{1}{252}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}\\=\frac{1\times \:1}{7\times \:252}$

$\mathrm{Multiply\:the\:numbers:}\:1\times \:1=1\\=\frac{1}{7\times \:252}$

$\mathrm{Multiply\:the\:numbers:}\:7\times \:252=1764\\=\frac{1}{1764}$

Hopes this helps you!

Have a wonderful night!

Happy Monday!
