Answer:
Surface Area Formula for a Rectangular Prism: A = 2( wl + hl + hw)
w = width
l = length
h = height
In this picture, it shows that the height is 4, the width is 2, and the length is 3. Therefore, we have:
A = 2 [ (2*3) + (4*3) + (4*2) ]
A = 2(6 + 12 + 8)
A = 2(26)
A = 52
Thus, the surface area is 52 cm^2.

What is the equation of the line that passes through the point (4, -4) and has a slope of -5/2
Answer:
y = -5/2x + 6
Step-by-step explanation:
y = -5/2x + b
-4 = -5/2(4) + b
-4 = -10 + b
6 = b

The local water slides have 72
employees, of which 25% are
temporary. How many
temporary employees are
there?
Answer:
18
Step-by-step explanation:
Step 1: Convert 25% to a fraction
[tex]\frac{25}{100}[/tex]
Simplify
[tex]\frac{1}{4}[/tex]
Step 2: Convert 72 to a fraction
[tex]72 = \frac{72}{1}[/tex]
Step 3: Set it up
[tex]\frac{1}{4}\times \frac{72}{1}[/tex]
Step 4: Cross divide
[tex]72 \div 4 = 18[/tex]
[tex]1 \div 1 = 1[/tex]
[tex]\frac{18}{1} = 18[/tex]
Therefore, the are 18 temporary employees in the local water slides.

Can someone please explain this question to me?
The image is attached.
Answer:
13
Step-by-step explanation:
Given the expression;
2 1/3 : 4 1/3 = 7 : x
Wea re to look for x;
Convert to improper fractions;
7/3 : 13/3 = 7:x
7/3 * 3/13 = 7/x
7/13 = 7/x
Cross multiply
7x = 13 * 7
7x = 91
x = 91/7
x = 13
Hence the unknown value is 13

You and your friends go to the state fair. It costs $6 to get into the fair
and $2 each time you go on a ride. Consider the relationship between
number of rides and total cost.
Model the equation to show the linear relationship.
Answer:
[tex]let \: number \: of \: rides \: be \: \: n \\ let \: cost \: be \: \: c \\ n \: \alpha \: c \\ n = kc \\ k \: is \: a \: costant \: of \: proportionality \\ when \: n = 1. \: \: c = 2 \\ 1 = (k \times 2) \\ k = \frac{1}{2} \\ therefore : \\ n = 0.5c[/tex]
Answer:
[tex]\huge\boxed{\sf x = 6 + 2y}[/tex]
Step-by-step explanation:
Let the total cost be x and number of rides be y
It costs $2 on each ride. So, the rides' cost will be:
=> Number of rides * One rides' cost
=> y * 2
=> 2 y
So, The total cost will be:
Total cost = Entrance cost + Rides' cost
Total cost = $6 + $2(Number of rides)
x = 6 + 2y

A computer program in Shannon’s computer carries out a single mathematical operation in 1.5 × 10-6 seconds. How much time would the program take to complete 2.5 × 103 mathematical operations?
1/1.5 * 10^-6 = 2500/x
x = 1.5 * 10^-6 * 2500
x = 0.00375 or 3.75 * 10^-3 second.
A fruit salad recipe calls for 3/4 pound of apples and 2/5 pound of dates. What is the least common denominator of the fractions?
Given:
A fruit salad recipe calls for [tex]\dfrac{3}{4}[/tex] pound of apples and [tex]\dfrac{2}{5}[/tex] pound of dates.
To find:
The least common denominator of the fractions.
Solution:
The given fractions are:
[tex]\dfrac{3}{4}[/tex] and [tex]\dfrac{2}{5}[/tex]
The denominators of these fractions are 4 and 5 respectively.
Factor form of 4 is 2×2.
5 is a prime number, so factor form of 5 is 5×1.
Now, the least common denominator of the fractions is:
[tex]LCD=2\times 2\times 5[/tex]
[tex]LCD=20[/tex]
Therefore, the least common denominator of the fractions is 20.
