Diego is buying shrimp and rice to make dinner. Shrimp
costs $6.20 per pound and rice costs $1.25 per pound.
Diego spent $10.55 buying shrimp and rice.
The relationship between pounds of shrimp s, pounds
of rice r, and the total cost is represented by the
equation 6.20s + 1.25r= 10.55.
Write an equation that makes it easy to find the number
of pounds of rice if we know the number of pounds of
shrimp purchased.
Answer:
r= (10.55−6.20s)
--------------------------
1.25
Step-by-step explanation:
Using the principle of subject of formula, we make number of pounds of rice, r the subject of the given equation. Hence, the equation would be r = (10.55 - 6.20s)/1.25
Given the expression :
6.20s + 1.25r = 10.55
Isolate 1.25r
1.25r = 10.55 - 6.20s
Divide both sides by 1.25 to isolate r
r = (10.55 - 6.20s)/1.25
Therefore, the required expression would be
r = (10.55 - 6.20s)/1.25

Need help with number 13
Answer:
x = 19
Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
x = 19
The perimeter of an equilateral triangle is 96 inches. If the length of each side is (2x + 6), find the value of x.
An equilateral triangle has three equal sides. Let's try to first find the actual value of each side of the triangle!
1. Let's first find the length of each side of the triangle in inches based on the information we know!96 inches is the perimeter of the triangle. The triangle has three equal sides. We can find the length of each side by dividing 96 inches by 3!
96 / 3 = 31 inches
The length of each side in the equilateral triangle is 31 inches.
2. Now, let's find x using the information we know!We know that the length of each side is 2x + 6, and we previously found that the length of each side in the equilateral triangle is 31 inches. We are trying to find x, so we can create an equation and isolate x!
31 = 2x + 6
-6 -6
25 = 2x
÷2 ÷2
12.5 = x
Yay, we just found x! That's the answer! Feel free to ask any questions if you need help. I'm not here to judge; I'm here to help. :)

the owner of an apple orchard ships apples in boxes that weigh 2 kilograms ( kg ) when empty. the average apple weighs 0.25 kg and the total weight of a box filled with apples is 12 kg. how many apples are packed in each box?
a. 14
b. 30
c. 40
d. 56
Given parameters:
Weight of box = 2kg
Average weight of an apple = 0.25kg
Total weight of box filled with apples = 12kg
Unknown:
Number of apples packed in each box = ?
Solution:
Since 1 apple weighs 0,25kg, let us find the weight of the apples in the box
Box + apples = 12kg
weight of box = 2kg
Weight of apples = 12kg - 2kg = 10kg
So;
0.25kg is the weight of 1 apple;
10kg of apples will equal [tex]\frac{10}{0.25}[/tex] = 40 apples
Therefore, 40 apples are packed in the box

Select the correct answer. Which number is a zero of h(x) = (x2 − 81)(x + 4)
A. 0
B. 4
C. 9
D. 81
Answer:
9 is a zero of h(x). C. Correct
Step-by-step explanation:
We want to find the zeros of the function
[tex]h(x) = (x^2 - 81)(x + 4)[/tex]
The zeros are the values of x that make h(x)=0, thus we need to solve the equation:
[tex](x^2- 81)(x + 4)=0[/tex]
Factoring:
[tex](x^2 - 81)=(x-9)(x+9)[/tex]
[tex](x-9)(x+9)(x + 4)=0[/tex]
This equation has 3 solutions:
x=9, x=-9, x=-4
A. 0 is not a zero of h(x). Incorrect
B. 4 is not a zero of h(x). Incorrect
C. 9 is one of the zeros of h(x) calculated above. Correct
D. 81 is not a zero of h(x). Incorrect
Answer:
C) 9

A survey of 73 students found that 37% were in favor of raising tuition to pave new parking lots. The standard deviation of the sample proportion is 9.8%. How large a sample (to the nearest person) would be required to reduce this standard deviation to 4.7%?
Answer:
The value is [tex]n_2 = 317[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 73
The proportion that in favor of raising the tuition is [tex]\^{p} = 0.37[/tex]
The standard deviation is [tex]s_1 = 0.098[/tex]
The required standard deviation [tex]s_2 = 0.047[/tex]
Generally the requires standard deviation is mathematically represented as
[tex]s_2 = s_1 * \sqrt{\frac{n_1}{n_2} }[/tex]
=> [tex]\frac{s_2}{s_1} = \sqrt{\frac{n_1}{n_2} }[/tex]
=> [tex]\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2[/tex]
=> [tex]\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2[/tex]
=> [tex]\frac{73}{n_2} =0.2300[/tex]
=> [tex]n_2 = \frac{73}{0.2300}[/tex]
=> [tex]n_2 = 317[/tex]
