Answer:0.24
Step-by-step explanation:
Answer:
0.24
Step-by-step explanation:
⅘% of 30
⅘ = 0.8
0.8% of 30
eg: 0.8 = x 30 = y
[tex]\frac{x*y}{100}[/tex] (this is the formula for calculating the percentage of a number)
[tex]\frac{0.8*30}{100}[/tex] = 0.24
For her science fair project, Madelyn is growing crystals with sugar water. She wants to know if the size of the container affects crystal growth. To start, Madelyn pours a sugar-water mixture into a small bowl. Then she pours triple the amount of the mixture into a large bucket. She decides to add red coloring so the crystals are more visible. Madelyn adds the same amount of red coloring to both containers. Which container's sugar-water mixture is a darker shade of red?
no links
The smaller container of sugar-water mixture will have the darker shade of red.
What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.
They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.
As per the given information in the question,
The experiment done by Madelyn is that,
Firstly, she has a small bowl where she pours as sugar-water mixture and in second case she pours tripe the amount of the mixture into a large bucket.
She adds the same amount of red coloring to both containers, then the smaller container or the small bowl will get the darker shade of red because the amount of mixture is less over there and the amount of color is same so, if you put the color in the larger one it will not get that red as compared to the smaller bowl.

Answer:
1. B 2. D 3. C 4. B
Step-by-step explanation:
1. If it takes 1/3 to make a scarf then you can make 3 with one yard of fabric and since there are five you do 3 times 5 to make 15.
2. Since you want to build 8 and you can't use the wood you cut up already. All you need is eight because each board makes 1 birdhouse.
3. If there are 12 then you take 3/4 on all of them you get 12 but then you have some left over and then you get 4 more 3/4 which makes your answer 16.
4. If you un-simplify 3/4 you get 6/8 and half of 6/8 is 3/8 which is your answer.
Hope this helps

Coach Cliffman made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Cliffman earned after 3years.
Answer: 5508$
Step-by-step explanation:
So to find interest your formula is this:
Int=interest rate (percent)*principal
So your problem would be: int=.02*1800
This equals 36. Since its interest, you add your interest (36) and your principal (1800) and get 1836. Now, since you need to find the interest for 3 years, you multiply 1836 by 3.

Select the correct answer from each drop-down menu.
A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 33, where x represents the smaller number. Plug in the numbers from the set {3, 5, 7, 9} to find the value of x.
The value of x that holds true for the equation is BLANK 1. So, the smaller number is BLANK 2 and the larger number is BLANK 3.
Blank 1:
3, 5, 7, 9
Blank 2:
