The correct statements that express ratio are;
b. For every 7 kids there need to be 3 pizzas.
c. The ratio of kids to pizzas is 7:3.
Here,
Diego estimates that there will need to be 3 pizzas for every 7 kids at his party.
We have to find the all statements that express this ratio.
What is Ratio?
A ratio indicates how many times one number contains another.
Now,
There are 3 pizzas.
Number of kids = 7
Hence, The ratio of pizzas to kids = 3 : 7 ( it can be read as 3 is to 7 )
And, For every 7 kids there need to be 3 pizzas.
The ratio of kids to pizzas = 7 : 3 ( it can be read as 7 is to 3 )
Therefore, The correct statements that express ratio are;
b. For every 7 kids there need to be 3 pizzas.
c. The ratio of kids to pizzas is 7:3.

An engineer is designing a runway for an airport. Several planes will use the runway and the engineer must design it so that it is long enough for the largest planes to become airborne before the runway ends. If the largest place accelerates at 3.30 m/s^2 and has a takeoff speed of 88.0 m/s then what is the minimum allowed length for the runway?
Answer:
d=117.33 m
Step-by-step explanation:
Initial velocity of planes, u = 0 (because they are at rest)
Acceleration, a = 3.3 m/s²
Final take off speed, v = 88 m/s
We need to find the minimum allowed length for the runway. Let it is d. d will be the distance. It can be calculated using third equation of motion as follows :
[tex]v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}[/tex]
Putting all the values, we get :
[tex]d=\dfrac{88^2-0^2}{2\times 33}\\\\d=117.34\ m[/tex]
Hence, the minimum allowed length for the runway is 117.33 m.

Ming works at a travel agency. Her base monthly salary is $1,750 plus 8% commission on her total sales for the year. Last year Ming sold $478,500 of travel. How much did ming earn, including commission, last year?
Answer:
59,280
Step-by-step explanation:
$1750x12months=$21,000 base sal.
478,500x.08=38,280 commiss.
21,000+38,280=59280
The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.
Ming earn, including commission, last year exists 59280.
What is meant by mathematical operation?Calculating a value using operands and a math operator is referred to as performing a mathematical "operation." The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers. In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.
Calculations in mathematics are done using arithmetic operators. A property or variable can be given a value using assignment operators. Text, dates, systems, times, and numeric assignment operators are all possible.
Given: Her annual sales commission is 8% of her base monthly salary, which is $1,750. Ming made $478,500 in travel sales last year.
From the given information, we get
$21,000 base salary = $1750 × 12 months.
478,500 × 0.08 = 38,280 commissions.
simplifying the above equation, we get
21,000 + 38,280 = 59280
Therefore, Ming earn, including commission, last year exists 59280.

Answer:
x = 2/3
Step-by-step explanation:
Lets solve your equation step-by-step.
x−10=−2(x+4)
Step 1: Simplify both sides of the equation.
x−10=−2(x+4)
x+−10=(−2)(x)+(−2)(4)(Distribute)
x+−10=−2x+−8
x−10=−2x−8
Step 2: Add 2x to both sides.
x−10+2x=−2x−8+2x
3x−10=−8
Step 3: Add 10 to both sides.
3x−10+10=−8+10
3x=2
Step 4: Divide both sides by 3.
3x / 3 = 2/3
x=2/3
A Boy Scout troop is selling Christmas trees at a local tree lot in the morning they sold 11 Douglas fir trees and nine noble fir trees turning a total of $1006 in the afternoon they sold 14 Douglas fir trees and nine noble fir trees turning a total of $1111 how much do the Douglasfir trees cost
Answer:
$35
Step-by-step explanation:
Let x represent the price of Douglas fir trees and y represent the noble fir trees
11x + 9y= 1006........equation 1
14x + 9y= 1111.........equation 2
Multiply equation 1 by 14 and equation 2 by 11
154x + 126y= 14,084
-
154x + 99 y= 12,221
27y= 1863
Divide both sides by the coefficient of y which is 27
27y/27 = 1863/27
y= 69
Substitute 69 for y in equation 1
11x + 9y= 1006
11x + 9(69) = 1006
11x + 621= 1006
11x = 1006 -621
11x = 385
x = 385/11
x = 35
Hence the Douglas fir free costs $35

8 waffle makers cost $200. If the waffle makers all cost the same amount, how much does each waffle maker cost?
Answer:
$25
Step-by-step explanation:
divide 200 by 8 to get the unit rate, or what a single waffle maker costs.
Answer:
Each waffle maker is $25.
Step-by-step explanation:
First set up an equation here mine would be:
200=8c (c being cost)
Next get c alone, so divide each side by 8. That gives you:
c=200/8
Simplify.
c=25
So the cost of each waffle maker is $25.

Answer:
y=-3x+3
Step-by-step explanation:
The equation you want to use is y=mx+b. First you want to find m, the slope, but since the slope of 3 is given in all of the answers, you just want to determine if the line is negative or positive. This line is going negative because it approaches the x axis, and crosses it in the negative direction. Now we know the slope is -3x all that's left to do is to find the y intercept represented in the equation y=mx+b as +b. The point where the line crosses the y axis is positive 3, so the final equation is y=-3x+3.

Steve is paid overtime for all time worked past 40 hours in a week. His regular-time pay rate is $12 an hour, and his overtime pay rate is $18 an hour. Last week Steve worked 47.3 hours. 1. How many regular-time hours did Steve work? 2. How many overtime hours did he work last week? 3. What was Steve's regular-time pay last week? 4. What was Steve's gross or total pay last week?
Answer:1. 40 hours 2).7.3 hours, 3).$480 4).$611.4
Step-by-step explanation:
STEP 1
stating all requirements
regular hour = 40 hours at $12 an hour
overtime = beyond 40 hours at $18 an hour
Step 2--- Solving out
1. Steve worked 40 regular time hours
2. Over time hours =Total 47.3 hours - 40 regular time hours = 7.3 hours
3. Regular time pay = Regular tmes hours x regular time pay rate
= 40 x $12 =$480
4) Steve gross pay = Regular time pay + overtime pay
= $480 + ( 7.3 hours x $18)
=$480+$131.4
=$611.4
Give an example of a balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5.
Answer:
An example of a balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5 is any integer belongs to [-6,-11]
Step-by-step explanation:
Let x be the balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5.
We are given that a balance that has a greater integer value than a balance of -$12
So, x>-12
We are given that balance represents a debt of less than $5.
Debt = -5
So, x< -5
So, -5>x>-12
So, x∈[-6,-11]
Hence an example of a balance that has a greater integer value than a balance of -$12, but represents a debt of less than $5 is any integer belongs to [-6,-11]

Founder's Park is planning to add a slide. The scaled model gives the reduced measures. A slide has a width of 3.5 inches and height of 3 inches. The park has space for the base of the slide to be 7-feet wide. To keep the slide proportional to the model, what will the height of the slide be? The slide will have a height of feet.
Answer: The slide will have a height of 6 feet.
Step-by-step explanation:
Given: A slide has a width of 3.5 inches and height of 3 inches.
For required slide , width = 7 feet]
To keep the slide proportional to the model,
[tex]\dfrac{\text{height of the required slide}}{\text{height of the slide }}=\dfrac{\text{width of required slide}}{\text{width of slide}}[/tex]
[tex]\Rightarrow\ \dfrac{\text{height of the required slide}}{3}=\dfrac{7}{3.5}\\\\\Rightarrow\ \dfrac{\text{height of the required slide}}{3}=2\\\\\Rightarrow\ \text{height of the required slide}=3\times2 =6\ \text{feet}[/tex]
hence, the slide will have a height of 6 feet.
Answer:
The slide will have a height of 6 feet.
