Answer:
It's the second answer
Step-by-step explanation:
It's the second question because the pattern is that the amount of food coloring is always 3 times more then the amount of frosting so it's point M because the amount of frosting is 50 so the amount of food coloring has to be 150 according to the ratio.

Two radio stations are playing this week's #1 hit song. One radio station plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3pm. How many minutes will pass before they play the same song again. (Only write the minutes.)
Answer:
1) 12
2) 72
Step-by-step explanation:
1) The GCF of 36 and 24 is 12. So, each child would get 3 prizes and 2 balloons.
2) The LCM of 18 and 24 is 72. When the first radio station is playing the song for the fourth time, the second radio station will play the song for the third time. This will happen 72 minutes after they both play it for the first time.
Answer:
1. 12 children
2. 72 minutes
Step-by-step explanation:
1. Find the GCF of 36 and 24, which is 12
2. Find the LCM of 18 and 24, which is 72

The 3rd semi-circle equals 31.
Step-by-step explanation:
Since the Pythagorean Theorem states that "The sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c)," we can find the answer of the 3rd semi-circle by finding the sum of each of the 2 smaller semi-circles and adding them together.

Given the expression: 4x10 − 64x2
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
Part B: Factor the entire expression completely. Show the steps of your work. (6 points)
Answer:
Step-by-step explanation:
a) 4x¹⁰ = 2² * x¹⁰
64x² = 2⁶ *x²
GCF = 2² * x² = 4x²
b) 4x¹⁰ - 64x² = 4x²*(x⁸ - 16)
=4x² *[ (x⁴)² - 4²]
= 4x² * (x⁴ + 4) (x⁴ - 4)
= 4x² * (x⁴ + 4)* [(x²)²- 2²]
=4x² * (x⁴ + 4) * (x² + 2)(x² - 2)

Answer:
y=15x+25, the cost is 205 dollars
Step-by-step explanation:
The simplest way to write a rule for this is to write it in slope intercept form, y=mx+b. Let y represent the cost of the membership. Every month the cost is 15 dollars. If we let x represent the months we can rewrite this as 15x. The one time cost is 25 dollars so we can just add that to the end of the equation. y=15x+25. There are 12 months in a year so we just have to substitute. y=15(20)+25=205 so the answer is 205 dollars.

Answer:
D
Step-by-step explanation:
Beacuse ♀️
Answer:
This is a rectangle, so if AB is equal to 3 centimeters, then DC is equal to 3 centimeters.
Since Angle X is equal to 45 degrees, then angle CDE, is also equal to 45 degrees, and we have an isosceles triangle, since angle CDE and DEC are equal to each other.
This means, that CE = DC.
And because E is the midpoint of CB, CE = EB.
So basically, we have:
DC = CE = BE
DC = 3
3 = CE = BE
And we see that CE and BE are both equal to 3, which makes CB equal to 6, which makes solving the area easy. (3 x 6), which is 18.
B is correct!
Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
Answer:
186 cm²
Step-by-step explanation:
*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.
*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.
Left rectangle:
A = lh
A = 12 (8)
A = 96 cm²
Right rectangle:
A = lh
A = 10 (9)
A = 90 cm²
Total:
A = 90 + 96
A = 186 cm²

Answer:
A, C, D, and F are the rational numbers.
one-half of the people at a game wore hats. two-thirds of those people also wore gloves. one-fourth of those people wearing gloves and hats also wore scarves. 25 of the people had hats and scarves but no gloves. One hundred people had only scarves. If there were 1824 people, how many had scarves
Please give answer as soon as possible
Final Answer: 277 people had scarves.
Step-by-step explanation:
1/2 people wore hats2/3 people wore also wore gloves.1/4 people wore scarves.25 people had hats and scarves. (no gloves)100 people have only scarves.1824 people total1824 / 2 = 912 (Divide by 2 to get the people wearing hats)
912 / 3 = 304 (subtract 304 to get 2/3)
912-304 = 608
608/4 = 152. (people who wore gloves, hats, and scarves.)
152+100+25= 277

Answer:
8
Step-by-step explanation:
You multiply the candies sold, by 8 to get the money raised.
10 times 8 is 80.
20 times 8 is 160
30 times 8 is 240
And so on.
I hope this helps!
pls ❤ and give brainliest pls
Divide money raised by candles sold:
80/10 = 8
160/20 = 8
Etc.
Each candle cost $8
You would multiply the number of candles sold by $8 to find the amount of money raised.
