An engineer makes a model of a bridge using a scale of 0.5 cm = 3 feet. The length of the actual bridge is 123 feet. What is the length of the model?
Answer:
20.5 cm
Step-by-step explanation:
Set up a proportion where x is the length of the model in cm:
[tex]\frac{0.5}{3}[/tex] = [tex]\frac{x}{123}[/tex]
Cross multiply and solve for x:
3x = 61.5
x = 20.5
So, the model's length is 20.5 cm

Answer:
Step-by-step explanation:
A soccer team must raise at least $660 buy new equipment. To reach this goal, each of the 12 soccer players sells tickets
to a game. Tickets cost $2.75 each. The school athletics fund donates an additional $10 per player. The situation is
modeled by the inequality shown,
12(2.75r + 10) 660
How many tickets must each player sell to raise the money?
A at least 19
B at least 17
C at least 16
D at least 20
Answer:
At least 17
Step-by-step explanation:
12(2.75r+ 10)≥ 660
33r+120≥ 660
33r≥ 540
r≥ 16.36
You can't sell 0.36 of a ticket to they need at least 17
At a store, a hat has a regular price of x dollars. During sale, the price of the hat
is discounted by 20%. The expression 0.8x describes the discounted price, in dollars,
of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answer:
x - 0.2x
Since the price of the hat is labelled = x,
The percentage discount on the hat price = 20%,
Thus, the discount = 20% of the price marked
= Twenty percent of x
=0.2 x =0.2 x
Therefore, the hat's new price = Marked price - Discount
= x- 0.2 = x
Answer:
D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x
A store pays $27 for a ticket to a play and marks the price up by 39%. What is the amount
of the mark-up?
Answer:
first, lets find 39% of 27.
39% of 27=10.53
10.53+27=
37.53
Determine the domain of the following graph:
Hi there! :)
[tex]\large\boxed{[-6, 6]}[/tex]
The domain of a graph consists of its x-values.
In this graph, we can see endpoints at the value x = -6 and x = 6.
Thus, the domain is from x = -6 to 6.
Since we have endpoints, however, we can use closed brackets "[]" to denote the domain in interval notation. Therefore, the domain of this function is:
[-6, 6].

You are in charge of renting SUVs and vans for your family reunion, and you want to minimize costs. You know that at most 40 children are attending and that at least 36 adults are attending. Each SUV accommodates 4 children and 3 adults, and costs $85 to rent. Each van accommodates 4 children and 4 adults, and costs $95 to rent. A. Set up the linear programming problem by writing the objective function as well as the system of constraints. B. How many SUVs and vans should be rented to minimize cost
Answer:
4 SUV, 6 vans
Step-by-step explanation:
Let x represent the number of SUV rented, and let y represent the number of vans to be rented.
Each SUV accommodates 4 children while Each van accommodates 4 children. Since there are at most 40 children who are attending, hence:
4x + 4y ≤ 40 (1)
Also, Each SUV accommodates 3 adults while Each van accommodates 4 adults. Since there are at most 36 adults who are attending, hence:
3x + 4y ≥ 36 (2)
The system constraints are:
4x + 4y ≤ 40 (1)
3x + 4y ≥ 36 (2)
x, y ≥ 0
b) The SUV cost $85 to rent and the van cost $95 to rent. Therefore the cost equation is:
Cost = 85x + 95y
From the graph, the solution to the constraints are (0, 10) and (4, 6).
At (0, 10); Cost = 85(0) + 95(10) = $950
At (4, 6); Cost = 85(4) + 95(6) = $910
Therefore the minimum cost is at (4,6). That is only 4 SUV and 6 vans should be rented
0.45m-9=0.9m
Subtract 0.45m from both sides
Answer:
Step-by-step explanation:
If you're trying to isolate the variable the first thing you would want to do is actually add 9 to both sides.
Answer:
-9 = 0.45m
Step-by-step explanation:
0.45m - 9 -0.45m= 0.9m - 0.45m

Answer:
Step-by-step explanation:
Adjacent angles when a line crosses another line must have a sum of 180 degrees.
52+2^(3x+1)=180
2^(3x+1)=128, 128=2^7 so
2^(3x+1)=2^7 which means

A farmer sells 7.8 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market? ;)
The farmer sold 1.95 kg of apples at the farmer's market.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
Given that a farmer sells 7.8 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples.
Since 3/4 of the weight is pears, then 1/4 of the weight must be apples.
We can find 1/4 of the weight by dividing 7.8 by 4:
7.8 kg ÷ 4 = 1.95 kg
So the farmer sold 1.95 kg of apples at the farmer's market.
