Answer:
Step-by-step explanation:
First you determine how much 15% of $7.06 is. ($1.06)
Then you subtract that from $7.06 which is $6.00.
Then you determine how much 25% of $6.00 is. ($1.50)
Then you subtract that off from $6.00, which gives you $4.50.
Final answer: $4.50

r. Parks spent $96.30 on 3 hats and 6 key chains.
a. If each hat cost $15.50, how much did each key chain cost?
Each key chain costs $
.
Question 2
b. Claire said each chain costs $0.83. Why is her answer unreasonable? Explain.
Answer:
1. $8.30
Step-by-step explanation:
so 3 hats were purchased and each cost 15.50 so
15.50*3=46.50
and the rest of the 96.30 is 6 keychains so
96.30-46.50=49.80
and there is 6 keychains
49.80/6=8.30
Each key chain was $8.30
Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.
The cost of each keychain is $5.79 which parks bought.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Parks spent $96.30 on 3 hats and 6 key chains and the cost of each hat is $15.50 and assuming the cost of each key chain to be 'x'.
Therefore, The expression that represents this context is,
3×15.50 + 6x = 96.30.
6x = 96.30 - 46.50.
6x = 49.8.
x = 49/8.6.
x = 5.79.
So, The cost of each key chain is $5.79.

32% of what weight is 60 oz
Answer:
200 oz
Step-by-step explanation:
Just use the equation
0.32x=200
The number of 32% which result in 60 oz would be 18.75
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.
We need to find the number that is state 32% of number weight is 60 oz
Let the unknown number is represneted by b.
It can be written by;
32% x b = 60
32/100 x b = 60
0.32 x b = 60
b = 60/0.32
b = 18.75
Therefore, the number would be 18.75

On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is an open circle. The right end of each segment is a closed circle. The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).

enter your answer and show all the steps that you use to solve this problem in the space provided. −→ g i bisects ∠ d g h so that m ∠ d g i is x − 3 and m ∠ i g h is 2 x − 13 . find the value of x.
So the value of x is 10
Given that line GI bisects angle DGH so that the measurement of angle DGI is x-3 and the measurement of angle IGH is 2x-13.
Since GI bisects that means the angle is cut into 2 equal angles or
DGI = IGH
Bisect means to cut into two even halves. If you bisect a 90 degree angle you create two 45 degree angles,
So by bisection
x - 3 = 2x - 13
Solving for x
13 - 3 = 2x - x
10 = x
or
x = 10
Therefore the value of x is 10.

2 _____________ 13.00
3 _____________ 19.50
Cost of package that weighs w pounds
If one pound = 6.50
2 pounds = 13.0
Then, the cost per pound = $6.50
Hence, cost of package that weighs w pounds will be ;
$6.50 * w = $6.50w

Layla opened a savings account and deposited 700.00 as principal the account earns 8%interest compounded annually what is the balance after 6 years
Answer:
The balance after 6 years is $1110.812026
Step-by-step explanation:
The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where
A is the new amountP is the initial amountr is the interest rate in decimaln is the number of periodst is the time in years∵ Layla opened a savings account and deposited $700.00 as principal.
∴ P = 700
∵ The account earns 8% interest compounded annually
∴ r = 8% = 8 ÷ 100 = 0.08
∴ n = 1 ⇒ compounded annually
∵ The time is 6 years
∴ t = 6
→ Substitute these values in the rule above
∵ A = 700[tex](1+\frac{0.08}{1})^{1(6)}[/tex]
∴ A = 700[tex](1.08)^{6}[/tex]
∴ A = 1110.812026
∴ The balance after 6 years is $1110.812026

Answer:
E: x = 13
F: x = 1.5 or 3/2
Step-by-step explanation:
This is for E:
x + 2/3 = 5
All you do is first multiply 5 * 3
and you will get 15
x + 2 = 15
Then you subtract from 15
15 - 2 = 13
So x = 13
This is for F:
10(x - 1) = 5
So all you do is distribute the 100 with x -1
10 * x = 100x
10 * -1 = 100
10x - 10 = 5
Then you add 10 to 15 because the number is -10
5 + 10 = 15
10x = 15
Now you divide by 10 on both sides
10x/10 = 15/10
10x/10 = x
15/10 = 3/2
So the answer for F is 3/2 or 1.5
