Answer:

Step-by-step explanation:

surface area = 2 × base + lateral area

base = (10×20)÷2 = 100

Lateral area = perimeter × height

= (20+14+14)×28

=1 344

Final answer :

surface area = 2 × base + lateral area

= 2 × 100 + 1344

= 200 + 1344

= 1544

Step-by-step explanation: (I'm not gonna' do it all for you tho)

to convert from percent to fraction:

70% = $\frac{70}{100} =\frac{7}{10}$

to convert from fraction to percent:

$\frac{11}{20}=\frac{55}{100}$ = 55%

to convert from fraction to decimal:

$\frac{3}{25} =\frac{12}{100} =0.12$

to convert from decimal to fraction:

$1.25=\frac{125}{100} =1\frac{25}{100} =1\frac{1}{4}$

to convert from percent to decimal:

0.2% = $\frac{0.2}{100} =0.002$

to convert from decimal to percent:

$0.4= (0.4*100)$ % = 40%

With that, you can solve the rest on your own

brooke found the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form as follows

Goryan [66]

Answer:

The equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is $\mathbf{y=-4x-3}$

Step-by-step explanation:

Equation of line passing through the points (-7,25) and (-4,13) in slope-intercept form.

The general equation of slope-intercept form is: $y=mx+b$

First we need to find slope

The formula used for finding slope is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We are given: $x_1=-7, y_1=25, x_2=-4, y_2=13$

Putting values in formula and finding slope

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{13-25}{-4-(-7)}\\Slope=\frac{13-25}{-4+7}\\Slope=\frac{-12}{3}\\Slope=-4$

So, slope m= -4

Now finding y-intercept

Using slope m=-4 and point (-7,25) we can find y-intercept

$y=mx+b\\25=-4(-7)+b\\25=28+b\\b=25-28\\b=-3$

So, y-intercept b =-3

Now, the equation of required line having slope m=-4 and y-intercept b=-3 is:

$y=mx+b\\y=-4x-3$

So, the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is $\mathbf{y=-4x-3}$
