Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
Which inequality represents the number of cars (C) Silvio must wash to reach his goal?
Answers
Answer:
50+12x≥158
Step-by-step explanation:
starting with $50, adding $12 for every car washed (x), must be at least, but can be greater than, $158.
The required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.
Given that,
Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
To determine the inequality represents the number of cars (C) Silvio must wash to reach his goal.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let the number of cars washed by Silvio be x,
According to the question,
Silvio works at a car wash. He earns $50 per day and $12 per car washed.
Total earning of the day = $50 + 12x
Silvio wants to earn at least $158 in 1 day. So, his total earnings of the day must be greater equal to $158.
$50 + 12x ≥ 158.
Thus, the required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Evaluate ∛-512 Use pencil and paper. Explain how you can check that your result is correct. Show your work.
nothing (Type an integer or a simplified fraction.)
Answers
Answer:
3√512 = 8
Step-by-step explanation:
Step 1: Find the prime factors of 512
512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2
Step 2: Pair the factors of 512 in a group of three, such that they form cubes.
512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)
512 = 23 × 23 × 23
Using the law of exponent, we get;
512 = 29 [am.an = (a)m+n]
Or
512 = (23)3 [(am)n = amn]
512 = 83
Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.
3√512 = 3√(83)
So, here the cube root is eliminated by the cube of 8.
Hence, 3√512 = 8

A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answers
Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students

Answers
Answer:
D-$4,900

Answers
Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
Answer: 3x + 2y = 30
Step-by-step explanation:
A = L x W
The sum of the rectangle is 30.
One angle is 3 and x, the other one is 2 and y.
Multiply 3 with x = 3x.
Multiply 2 with y = 2y
Then create your equation plugging in 30 as the answer to 3x + 2y
