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

Whats is 7 = 12v - 24?
Answers
Answer:
To the nearest tenth: v = 2.6
To the nearest hundredth: v = 2.58
Fraction form = 31/12
Step-by-step explanation:
1. Add 24 to both sides to cancel it out on the right
7 = 12v - 24
+24 +24
2. Divide each side by 12
31 = 12v
31/12 = 2.5833333
12/12 = 1v = v
v = 2.583333
(1). 7=12v-24 (12v is a variable so you move it left hand side and change its sign)
(2). 7-12v=-24 (7 is a constant so move it to the right hand side and change its sign)
(3). -12v=-24-7 (now calculate the difference -24-7)
(4). Now it’s -12v=-31, now after that divide both sides of the equation by -12
(5). So the answer is V=31/12

An instrument store has 20% clearance on every instrument. A guitar originally costs $120. You take it to the cashier and they charge a sales tax of 5%.
How much did you pay for the guitar?
Answers
Answer:
P = $100.80Steps:
Price after clearance:Pc = 120 - (120/100×20)
Pc = 120 - (1.2×20)
Pc = 120 - 24
Pc = 96
Price after sales tax:P = Pc + (Pc/100×5)
P = 96 + (96/100×5)
P = 96 + (0.96×5)
P = 96 + 4.8
P = $100.80
Answer:
I’m pretty sure the answer would be $100.80
Step-by-step explanation:
1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)
2. Subtract $120-$24= $96
3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8
3. Add $96+$4.80= $100.80

Answer:
$367.38 is the cost to stain the entire deck.
Step-by-step explanation:
Here is what you need to know beforehand:
Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.
--------------------------------------------------------------------------------------------------------------
First, find the area of the circle. Here is the formula:
Area = 3.14 (Pi) x r²
Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m
So the formula will look like this:
Area = 3.14 x 6²
Then, you just do the math:
Area = 3.14 x 6²
Area = 3.14 x 36
Area = 113.04
The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:
Answer = 113.04 x 3.25
Answer = 367.38
$367.38 is the cost to stain the entire deck.

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.

During vacation, Dave and his brother, Scott, rode their bikes from their family's rental house to a pond to go fishing. Although they left the rental house together, Dave arrived at the pond a few minutes before Scott. This weekend, they plan to ride a nearby mountain trail and turn back after an hour if they can't complete it. Who will likely ride farther along the mountain trail?
Answers
Answer:Dave
Step-by-step explanation:
If we are thinking logically, since dave arrived at the pond first even though they left at the same time, he should go farther because he is more athletic based on the information.

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
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

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.
If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?
Answers
Marcellus's eyes should be 5 cm apart
If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;
Marcellus eyes are 1x far apart as Dan's eyes.
If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.
Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.
Essentially, Marcellus's eyes will be just as wide as Dan's eyes
