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?
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
Good luck!!
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?
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

What is the area of the figure shown?
Step-by-step explanation:
[tex]3.5 \times 6 + (5 - 3.5) \times 6 \div 2 = \\ = 21 + 9 \div 2 = \\ = 25.5[/tex]
Answer:
25.5m
Step-by-step explanation:
square area: 6m*3.5m = 21m
Triangle height: 5m - 3.5m = 1.5m
Triangle area: [tex]\frac{1.5m*6m}{2}[/tex] = 4.5m
Total area: 21m + 4.5m = 25.5m
hiii umm yeah i need help on this its about direct variation equations
Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1
so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

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?
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

I need help with this question.
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.
