Answer:
They are saying that they have this conference room mapped out on a poster board kinda like a road map. But if you put something that big on a board it wont fit. So they had to make it small enough to fit it. When they say that 1/2 on the board is equal to 12 feet in the real room, They are tell you the scale you have to go by. So then they give you 3 1/2 inches on the board. You would see how many 1/2 inches there are in 3 1/2, which is 7, and multiply 7 by 12. The answer would be 84 feet. So they are say that 3 1/2 inches on the poster board, represents 84 feet in the real room.

Find the slope...........
Answers
Point A: (3, -1)
Point B: (1, 2)
Then we will use the slope formula to work out the slope:
y₂ - y₁ / x₂ - x₁
Substitute in our points:
2 - (-1) / 1 - 3
Then we work out the expression (remember a negative and a negative make a positive!):
3 / -2
Then we check if we can simplify this fraction, which in this case we cannot.
Therefore the slope of that line would be:
3 / -2
(remember to write it as a fraction!)

Answers
Answer:
The ratio of bananas to total fruit is 13:21
Step-by-step explanation:
Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.

[tex]8\times5=40[/tex]
[tex]3\times4=12[/tex]
[tex]=\frac{40}{12}[/tex]
Reduce:
[tex]40\div4=10[/tex]
[tex]12\div4=3[/tex]
[tex]=\frac{10}{3}[/tex]
Convert into mixed number:
[tex]\frac{10}{3} =3\frac{1}{3}[/tex]

Step-by-step explanation:
The perimeter of the original rectangle on the left is 30 meters. The perimeter of the reduced rectangle on the right is 24 meters. What is x, the width of the original rectangle on the left? Round to the nearest hundredth if necessary.
A) 5 meters
B) 8 meters
C) 10 meters
D) 12 meters
Answers
Explanation:
If the triangle on the rights perimeter is 24 and two of the lengths are 8 then we know 8+8=16 24-16=8 8/2=4
So the triangle on the right has the numbers 8 and 4 as it’s length and width
So then you would find out how much it was dilated to get from 30 to 24
30/24 and you get 1.25 so you multiply 4 by 1.25 and get 5, and then to double check you can multiply 8 by 1.25 and get 10 then add it all together
5+5+10+10=30 so you know that’s correct.

In a class of 42 students, 18 students are in the Math Club, 5 students
are in both the Math Club and the Science Club, and 14 are in neither. How many
students are in the Science Club?
Answers
Answer:
15 maybe?
Step-by-step explanation:
42 - 14 = 28
18 - 5 = 13
28 - 13 = 15
subtract the 14 because it says it is in neither.
Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.
Subtract 13 from the 28 because those 13 are in math and wont be in science also.

Solve the inequality $-4x > -24.$ Give your answer in interval notation.
Answers
Answer:
(negative infinity, 6)
Step-by-step explanation:
To get this:
1. -4x > 24
Divide by -4
2. x < 6
When you divide by a negative you have to flip the inequality. Therefore, any number that is less than 6 is the answer.
The solution of the inequality will be;
⇒ x ∈ (- ∞, 6)
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ - $4x > - $24
Now,
Solve the inequality as;
The inequality is,
⇒ - $4x > - $24
Multiply by - 1, we get;
⇒ $4x < $24
Divide by 4, we get;
⇒ x < 6
⇒ x ∈ (- ∞, 6)
Thus, The solution of the inequality will be;
⇒ x ∈ (- ∞, 6)

Could someone please find the rate and y-intercept for these two points? (2,2) and (3,4) the help would be greatly appreciated!!
Answers
so a formula most commonly used is (y^1-y^2)/(x^1-x^2)
m= (y^1-y^2)/(x^1-x^2)
=m=(4-2)/(3-2)
=m=2/1
2/1 can also be expressed as just 2 since anything divided by 1 is just itself
Now use the formula y=mx+b to find the y intercept
use either of your two given point to susitute y and x
y=mx+b
Substitute your values
=(4)=(2)(3)+b
Calculate
=4=6+b
Subtract both sides by 6
=-2=b
Therefore the rate of change is 2/1 and the y-intercept is -2

At the start of the month, the value of Susan’s checking account was $53. She gets paid $375 per week for 4 weeks and spends $172 on groceries for the month. How much does Susan have in her checking account at the end of the month?
Answers
Because 375×4= 1,500
and 1,500-172= 1,328
lastly, 1,328 + 53= 1,381
[ 53 + (375x4) ] - 172
Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.
Answers
Answer:
9.55 minutes
Step-by-step explanation:
x hours to go to the river
0.25-x hours to come back, since 15 minutes is 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
those two are equal
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes
