Answer:
Hi liddywiddy, sorry you had to wait so long
There are 20 teachers in all
Step-by-step explanation:
the ratio 3:2 is now 12:x
12 / 3 = 4
so the multiplier is 4
now:
4x2 = 8
Next we add them: 12+ 8 = 20
Answer:
20 teachers in all
Step-by-step explanation:
12 / 3 = 4,
4 * 2 = 8,
so 12 + 8 = 20

What is the BODMAS rule?According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.
Given here the expression 4/5×15 thus simplifying it we get
4/5×15= 4×3
= 12
Hence, The expression equivalent to 4/5 × 15 is 4×3

8) Tayna made a mistake in her work. Identify the mistake and explain how she could fix the mistake. *
How many degrees are there in the "Department Store" angle? *
How many degrees are there in the "Gas Station" angle? *
Answer:
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75
Step-by-step explanation:
The mistake is 7x+8+x+22 should not equal 90. It should equal 180 degrees because the two angles are supplementary angles. (It forms a straight line)
Correct equation and how to solve for X:
7x+8+x+22=180
8x+30= 180
8x= 150
x=18.75
Department Store:
7(18.75)+8= 139.25
Gas Station:
18.75+22= 40.75

What will be the area of this parallelogram?
Include the appropriate unit in your answer.
Answer:
13.75 square feet
Step-by-step explanation:
all you have to do to find the area of a parallelogram is base * height
= 2.5 * 5.5
= 13.75 square feet
Answer:
13.75 ft^2
Step-by-step explanation:
I) Substitute equation to find the area
a = hb (area = height x base)
a = 2.5(5.5)
II) Solve:
a = 2.5(5.5)
a = 13.75
The area is 13.75 ft^2.
the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter reprecents 20 kilometers. what is the actual distance between these two cities in kilometers?
Answer:
70 kilometers
Step-by-step explanation:
Set up a proportion where x is the actual distance
[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]
Cross multiply:
x = (20)(3.5)
x = 70
So, the actual distance is 70 km

There were 140 geese living in Larson Lake last year. It is overpopulated. A scientist has suggested a program to decrease the population of geese by 15% after 5 years. How many geese does the scientist hope will be in the lake in 5 years? Show your work.
Answer:
119
Step-by-step explanation:
Find 10% by dividing by 10, then halve it to get 5%. The answers are 14 and 7 accordingly.
Add them together to get 15%, which is now 21.
Take 21 off of 140 to get the answer, which is 119.
ALTERNATIVE METHOD - CALCULATOR
To solve the question using a calculator and with only one equation, multiply the number by 0.85 to find 85% of the number, and there's your answer.
If a man walks at the rate of 3 feet per second, how many minutes will it take him to walk 5760 feet?
Answer:
32 minutes
Step-by-step explanation:
There are 60 seconds in a minute
That means we will need to know how many feet he walks in a minute
So we would do 3 x 60 which equals 180 so he walks 180 ft per miute
Now we need to figure out how many minutes it took for him to walk 5760 ft.
So we would do 5760 ÷ 180 which equals 32
So the aswer is 32 minutes for him to walk 5760 ft.
Hope this helps
A math student has a plan to solve the following system by the elimination method. To eliminate the x-terms, he wants to multiply the top equation by 7. What
should he multiply the second equation by so that when he adds the equations, the x-terms are eliminated?
-3x-7--56
-7x+10y - 1
Answer:
-3
Step-by-step explanation:
7(-3x-7y-56)
-21x-49y-392
-3(-7x+10y-1)
21x-30y+3
because the eq. multiplied by 7 is negative, the second eq mus be positive in order to eliminate the x variable. this is why we multiply by a (-). by multiplying the second eq by 3, both eq. will result in a coefficient of 21. one positive one negative allowing the x variable to be eliminated from the problem.
