Gabe made a rectangular sandbox for his brother to play in. Gabe wants to paint only the sides of the sandbox. A prism has a len

alukav5142 [94]

Answer: The surface area of the sides of the sandbox that Gabe wants to paint is 47ft2

Step-by-step explanation:

Hi to answer this we have to apply the formula:

Surface Area of a rectangular prism = 2lw + 2wh + 2lh

Where:

l= length

w= width

h= height

Since the sandbox is open , it has one less surface (length x width), we have to add only one lw term.

Surface Area of the sandbox = lw + 2wh + 2lh

A = (4x5) + 2( 5x1.5) + 2( 4x1.5)

A = 20+15+12

A= 47 ft2

What I the equation in standard form of the line that passes through the points(4,-8) and has a slope of 1/4

valentinak56 [21]

Answer:

Standard form of the line with point (4,-8) and slope of 1/4 is

-x + 4 y = -36.

Step-by-step explanation:

The slope of the line equation = 1/4

The point is given as (4,-8).

Now, by POINT SLOPE formula,

The line equation with slope m nad point (x0,y0) is given as:

(y - y0) = m (x -x0)

So, the line equation here is given as

$y -(-8) = \frac{1}{4} (x -4)\\\implies 4(y + 8) = x - 4\\4 y + 32 = x - 4\\4y = x - 36$

Now, the standard form of line equation is Ax + By = C

Here, 4y = x - 36 ⇒ 4y - x = -36

or, -x + 4y = -36 is the standard form.

Hence,standard form of the line with point (4,-8) and slope of 1/4

is -x + 4y = -36.

George works as an office clerk and his office job pays him $12 per hour. Dorothy works as a cashier and her job pays her $11.25

Phoenix [80]

You will need 2 equations, since there are 2 variables (hours worked by George and the ones of Dorothy), let's say x and y respectively

We know
x+y=48 (since they work 48 hours together) and
12x+11.25y=555 (since the sum of their respective hours multiplied by their salary gives a total of 555$)

To solve that, you can isolate either one of the variables and replace it in the second formula, for example:

x+y=48, therefore x=(48-y)
Substitute x in 12x+11.25y=555 and solve for y (to find Dorothy's hours)
12(48-y)+11.25y=555
576-12y+11.25y=555
21=0.75y
y=28
