What is the surface area of a rectangular prism with the following dimensions? length: 8 cm width: 13 cm height: 10.5 cm

1 answer:

5 0

Height by width face = 10.5 * 13 = 136.50 sq cm height by length face = 10.5 * 8 = 84 sq cmwidth by length face = 13 * 8 = 104 sq cm

Since there are TWO of those faces, we get the total and multiply it by 2.
Total = 324.50 sq cm * 2
TOTAL AREA = 649 sq cm

Percy works two part-time jobs to help pay for college classes. On Monday, he works 3 hours at the library and 2 hours at the co

laila [671]

For the answer to the two questions above,
3x + 2y = 36.50 (I)
2x + 5y = 50 (II)
Eliminating x from the two equations by subtraction:
first we multiply equation I by 2 and equation II by 3
6x + 4y = 73
6x + 15y = 150
Subtracting the two,
-11y = -77
y = 7
He earns $7 at the coffee cart
Substituting y into equation I,
3x + 14 = 36.5
x = $7.50

So we can conclude that, he earns a greater wage of $7.50 at the library,

A.) write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5.

marta [7]

Slope intercept form is y = mx + b

7 tickets for $5 means that 1 ticket costs 5/7 dollars

So for part a, the slope intercept form would be:

$y = \frac{5}{7}x$

where x is the number of tickets, and y is the price.

For part b)

The slope intercept form is:
$y = 25x$

where x is the number of all you can ride wristbands you buy, and y is the total price.
