Answer:
Step-by-step explanation:
If a lift will carry 8 people safely with an average mass of 75kg each we multiply to find the weight the lift can safely carry.
8 x 75kg = 600kg
If the average mass of the people is 100kg each, we divide to find the number of people it can carry. We know the lift can carry 600kg.
600kg/100kg = 6
So the lift can carry 6 people if their average mass is 100kg.
The following linear system is to be solved using a
substitution method.
x = 4y - 94
3x + 8y = 218
After the initial substitution, the resulting expanded
equation would be
A. 12y – 282 +8y = 218
B. 3x + 32y – 94 = 218
C. 3x + 32y – 752 = 218
D. 12y - 94 + 8y = 218
Answer:12y-282+8y=218

Is this graph a function?
Answer:
Depends; it is a function of y because each y value maps out to only 1 x value, but it is not a function of x, because for x = 3 y maps out to infinite values.

Carly wants to buy some fish to keep in her room. At a local pet store customers can pay
$12.50 for a fish tank and $0.20 for each fish they purchase.
a. What is the slope or rate of change in the situation described? Explain.
Answer:
12.50
Step-by-step explanation:
Im not completely sure on this but the answer is 12.50 because it states that the price for a fish tank is $12.50. So im pretty sure that the intercept is that.
The Slope here is $0.20 which represent cost of each fish.
What is Rate of Change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Given that, Carly wants to buy some fish to keep in her room. At a local pet store, customers can pay $12.50 for a fish tank and $0.20 for each fish she purchased,
Let total cost be C, and total number of fish be n
According to question,
C = 12.50 + 0.20n
Hence, the slope 0.20 represents the change in total cost as the number of purchase of fish changes.

Which fraction is BIGGER?
-7/10 or -4/5
Hello.
Negative numbers closest to 0 are the greatest.
-7/10 is farther away from 0 than -4/5 is.
-7/10 < -4/5, so -4/5 is the bigger fraction.

The expression represents the second consecutive odd integer is X + 2
and for the third consecutive odd integer is X + 4.
What are integers?All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a set of integers is formed.
An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.
Given One example of consecutive odd integers would be 3, 5, 7, 9, ...
the difference between 2 consecutive numbers is
5 - 3 = 2
when X is the first odd integer,
the second consecutive odd integer is X + 2
difference between 3rd and first digit is
7 - 3 = 4
the third consecutive odd integer is X + 4
Hence adding the consecutive even numbers to the first digit of odd numbers gives the consecutive odd numbers.

If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?
Answer:
36.16 miles
Step-by-step explanation:
A recycling truck begins its weekly route at the recycling plant at point A, as pictured on the coordinate plane below. It travels from point A to point B, then points C, D, and E, respectively, before returning to the recycling plant at point A at the end of the day. The truck’s route is illustrated on the coordinate plane below. If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?
Answer:
The distance between two points X([tex]x_1,y_1[/tex]) and Y[tex](x_2,y_2)[/tex] is given as:
[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
From the image attached, the coordinates of the plane are:
A(-1, -1), B(1, -1), C(5, 2), D(0, 13), E(-5, 2).
The lengths are:
[tex]|AB|=\sqrt{(1-(-1))^2+(-1-(-1))^2}=2\ units\\ \\|BC|=\sqrt{(5-1)^2+(2-(-1))^2}=5\ units\\\\|CD|=\sqrt{(0-5)^2+(13-2)^2}=12.08\ units\\\\|DE|=\sqrt{(-5-0)^2+(2-13)^2}=12.08\ units\\\\|AE|=\sqrt{(-5-(-1))^2+(2-(-1))^2}=5\ units[/tex]
But 1 mile = 1 unit
Total distance = |AB| + |BC| + |CD| + |DE| + |AE| = 2 + 5 + 12.08 + 12.08 + 5 = 36.16 miles
