0.75 of the adults in a hall are women. If there are 125 men, how many adults are there altogether?

Answers

I think the answer is 500
If there are x adults total, and 0.75 of them are women, then you have 0.75x women total. it is given that you have 125 men.
since men plus women equals total adults, 0.75x+125=x
125=0.25x
x=500

An art teacher makes a batch of purple paint by mixing 3/4 cup red paint with 3/4 cup of blue paint. If she mikes 13 batches, how many cups of purple paint will she have?

Answers

She will have 19.5 cups of purple paint.
I couldn’t write the explanation of how you get the answer, but look your question up on Brainly and it’ll give you your explanation.

Hope this helped! :)

Answer:

She will have 19 ¹/₂ batches of purple paint

Step-by-step explanation:

r + b = 1 bp

³/₄ r + ³/₄ b = 1 bp

(³/₄ + ³/₄) * 13 = x bp

⁶/₄ = 1 ¹/₂

1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches

VARIABLE KEY:

r = red

b = blue

bp = batches of purple

x = total number of bp

Answer:

Step-by-step explanation:

Answer:

If you used π, 157.079632679 yards or 157.08 yards rounded to the hundredths place. If you used 3.14, the answer is 157 yards.

Step-by-step explanation:

The formula to find the perimeter of a circle is P=2×π×r.

Step 1: Find the radius. In this case, the radius is 25 yards as shown in the diagram.

Step 2: Since the formula only includes multiplication, you can multiply any of the factors. For simplicity, multiply your radius by 2 first. In this case, 2×25=50.

Step 3: Multiply your last number with π. In this case, 50×π=157.079632679 or 157.08 rounded the hundredths place. 50×3.14=157.

Step 4: You found the answer! Hope this helps.

whats an equation equal to 10x-5​

Answers

the answer should be -50

Answer:

-50

Step-by-step explanation:

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)


Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000


Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.


Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12


Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.

solve the equation -2(x-5)=-14

Answers

Answer:

x=12

Step-by-step explanation:

-2(x-5)=-14

x-5=-2/-14

x-5=14/2

x-5=7

x=5+7

x=12

X =12. Multiply it out. -2x +10= -14. -2x=-14-10. -2x= -24. Divide both sides by -2. Hope this helps!

Answers

Answer:

108 degrees

Step-by-step explanation:

By the Exterior Angle Theorem:

(2x + 1) + 63 = 5x -2

2x + 64 = 5x - 2

66 = 3x

22 = x

Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:

5(22) - 2

110 - 2

108

The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)
