A collection of coins contains a total of sixteen dimes and quarters. It is worth $2.20 in all. How many dimes are in the collection?
9514 1404 393
Answer:
12 dimes
Step-by-step explanation:
Let q represent the number of quarters. Then the number of dimes is 16-q and the total value is ...
0.25q +0.10(16 -q) = 2.20
0.15q +1.60 = 2.20 . . . . . . . simplify
0.15q = 0.60 . . . . . . . . subtract 1.60
q = 4 . . . . . . . . . . . divide by 0.15
16-q = 12
There are 12 dimes in the collection.

Finding the lengths of a Triangle is [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
Your triangle is [tex]7^{2}[/tex] + [tex]b^{2}[/tex] = [tex]25^{2}[/tex]
Which is 49 + b = 625
Subtract the difference 625 - 49. then you get the following
b = 576

[tex] \sqrt{ {4 a}^{2} + {12a}^{2} } [/tex]
Answer:
The answer is 4a
Step-by-step explanation:
1) Simplify 4a² + 12a² to 16a².
[tex] \sqrt{ {16a}^{2} } [/tex]
2) Use this rule:
[tex] \sqrt{ab} = \sqrt{a} \sqrt{b} [/tex]
[tex] \sqrt{16} \sqrt{ {a}^{2} } [/tex]
3) Since 4 × 4 is 16, the square root of 16 is 4.
[tex]4 \sqrt{ {a}^{2} } [/tex]
4) Simplify.
[tex]4a[/tex]
Therefor, the answer is 4a.

Paula, the local baker, usually makes 1"5 loaves of bread and 10 cakes per day, but today she made 25 loaves of bread and 12 cakes. What is the percent increase far each bakery item?
Answer:
the percentage increase for bread and cake is 66.67% and 20% respectively
Step-by-step explanation:
The computation of the percentage increase for each bakery item is shown below:
For bread
= (25 - 15) ÷ 15
= 66.67%
For cakes
= (12 - 10) ÷ (10)
= 20%
Hence, the percentage increase for bread and cake is 66.67% and 20% respectively

Mrs. Anderson's closet consists of two sections, each shaped like a rectangular prism. She plans to buy mothballs to keep the moths away. She needs one box for every 16 cubic feet of space. How many boxes should she buy? Explain how you found the answer.
Answer:
13 boxes
Step-by-step explanation:
Given
See attachment for closet
Required
Determine the number of boxes needed to fill the closet
First, we calculate the volume of the two section.
[tex]Volume = Width * Length * Height[/tex]
From the attachment
The first section is:
[tex]Width = 5ft\\ Length = 4ft\\ Height = 8ft[/tex]
[tex]V_1 = 5ft * 4ft * 8ft[/tex]
[tex]V_1 = 160ft^3[/tex]
The second section:
[tex]Width = 3ft\\ Length = 2ft\\ Height = 8ft[/tex]
The width is the last label at the top
The length is the difference between the length of the first section (4ft) from the total length of the closet (6ft) i.e. 6ft - 4ft
The volume is:
[tex]V_2 = 3ft * 2ft * 8ft[/tex]
[tex]V_2 = 48ft^3[/tex]
Total volume (V) is:
[tex]V = V_1 + V_2[/tex]
[tex]V = 160ft^3 + 48ft^3[/tex]
[tex]V = 208ft^3[/tex]
The number of box (n) needed is then calculated by dividing the calculated volume of the closet by the volume of each box
[tex]n = \frac{208ft^3}{16ft^3}[/tex]
[tex]n = 13[/tex]
