Question 2: You want to donate 30% of the $400 earned at your yard sale to
charity. How much should you donate?
What is 10% of the total?
Your answer
What will 30% be?
Your answer
Answer:
10%= 40$ 30%=120$
Step-by-step explanation:
ok so u earn 400$ at a yard sale. you divide it by 100 400/100=4. ok so then you multiply four by 10=40 and that is 10% multiply it by 30 u get 120 or 30%
sorry for the bad spelling
To find out how much to donate, you need to understand what percentage means. 10% of $400 is $40 and since 30% is 3 times as much, you should donate $120.
Explanation:To solve this problem, you first need to understand what 10% of a quantity means. 10% of a quantity is simply that quantity divided by 10. If you want to donate 30% of the $400 earned at your yard sale to charity, you first need to find 10% of $400, which is $400 divided by 10. This gives you $40.
Since 30% is the same as three times 10%, you just need to multiply your answer for 10% by 3. Therefore, you should donate $40 times 3, which equals $120.

Step-by-step explanation:
To work out the original number you would need to work backwards ( do the opposite). First you would do 22-5, this gives us 17. Then you would divide 17 by 2 to work out the original number.
1) Subtract 5 from 22.

Vincent started the year with $231 in his account at the health spa. Each time he uses the spa, $6 is taken out of the account. How many more times can he use the spa if he has already had $48 taken out of his account this year?
Answer:
Vincent would have 30.5 more visits, but since you can't have half a visit technically speaking, round up to 31 if it is allowed.
Step-by-step explanation:
$231 - $48 = $183

The function y = 10 x + 190 represents the relationship of the given data where x represents fat, in grams, and y represents calories.
How many calories would there be in a snack with 35 grams of fat?
Answer:
540 calories
Step-by-step explanation:
We are trying to find y (calories), when x (fat) equals 35 grams.
So, we can substitute 35 in for x
y= 10x +190
y=10(35)+190
Multiply 10 and 35
y=350+190
Add 350 and 190
y=540
A snack with 35 grams of fat will have 540 calories

Candice is an interior designer, and she is currently trying to change the look of a room. Candice found that the area of a room could be given by the expression 3x2 + 2x. The aread of the rug she wants to spread on the floor is given by the expression x2 + 24x - 144. What expression represents the area of the room not covered by the rug?
Answer:
[tex]A(x) = 2x^2-22x+144[/tex]
Step-by-step explanation:
We are given the following in the question:
Area of room =
[tex]3x^2 + 2x[/tex]
Area of rug =
[tex]x^2 + 24x - 144[/tex]
We have to find the area of of the room not covered by the rug.
Area of of the room not covered by the rug =
Area of room - Area of rug
[tex]A(x)=(3x^2 + 2x) - ( x^2 + 24x - 144)\\A(x)=3x^2 + 2x-x^2 -24x + 144\\A(x)=(3x^2-x^2)+(2x -24x) + 144\\A(x)=2x^2-22x+144[/tex]
is the required expression for the area of floor not covered by the rug.
If people blink about 13 times per minute, how many times do they blink in 7 hours?
Answer:
Step-by-step explanation:
1 hour=60 min
7 hours=60×7=420 min
number of blink=420×13=5460
Final answer:
To calculate the number of times a person will blink in 7 hours at a rate of 13 blinks per minute, you multiply 13 by the total number of minutes in 7 hours (420) to get 5,460 blinks.
Explanation:
If people blink about 13 times per minute, we can calculate how many times they blink in 7 hours by multiplying the number of blinks per minute by the number of minutes in 7 hours. First, let's find out how many minutes are in 7 hours:
7 hours x 60 minutes per hour = 420 minutes
Now, we'll multiply the number of minutes by the number of blinks per minute:
420 minutes x 13 blinks per minute = 5,460 blinks
Therefore, a person will blink 5,460 times in 7 hours. This is a simple arithmetic multiplication problem that provides us with the total number of blinks over a given period.
Find the measure of angle BCD in the following parallelogram. what's does BCD equal
Answer:
120 degrees
Step-by-step explanation:
This is a quadrilateral, and by definition, the sum of all the interior angles is 360. So, we can just sum up all the expressions and set them equal to 360:
2x + x + 2x + x = 360
Combine like terms and solve for x:
6x = 360
x = 360/6 = 60
<BCD = 2x = 2 * 60 = 120
Thus, the answer is 120 degrees.
Hope this helps!

Find the area of the shaded regions.
Answer:
84.82 or 27pi
Step-by-step explanation:
Area of a circle is A=pir^2
so the area of the whole circle would be 6^2pi
so area is 36pi but only 3/4 is shaded so
36pi*3/4=27pi
27*pi≈84.82
Answer:
84.78cm²
Step-by-step explanation:
Angle at the centre:
360 - 90 = 270
Area:
(270/360) × pi × r²
(3/4) × pi × 6²
27pi cm²
27(3.14) = 84.78 cm²

Answer:
x + a + 2
Step-by-step explanation:
g(a) = a² + 2a
g(x) - g(a) = x² + 2x - a² - 2a
= x² - a² + 2x - 2a
= (x - a)(x + a) + 2(x - a)
= (x - a)(x + a + 2)
[g(x) - g(a)] ÷ (x - a)

We can use the base formula: [tex]a_n=a_1+(n-1)d[/tex]
[tex]a_n[/tex] = nth term
[tex]a_1[/tex] = first term
[tex]n[/tex] = position of the term
[tex]d[/tex] = common difference
First, lets find the common difference of the sequence.
12 - 5 = 7
19 - 12 = 7
26 - 19 = 7
Second, find the variables we already know.
[tex]a_1[/tex] = 5
[tex]d[/tex] = 7
Put these values into the formula: [tex]a_n = 5+(n-1)7[/tex]
We can use this expression to solve for the fifth term.
[tex]a_5=5+(5-1)7\\a_5=5+(4)(7)\\a_5=5+28\\a_5=33[/tex]
Therefore, the answer is [tex]a_n = 5+(n-1)7[/tex]

Ethan and Evan are twins. They each deposit $3,000 into separate bank
accounts. Ethan's account accrues interest at a rate of 8% annually. Evan's
account compounds interest at a rate of 8% annually. Which of these
accounts can be modeled by linear &/or exponential. Explain why?
Evan's account can be modeled by exponential growth because it compounds interest. Ethan's account can be modeled by linear growth because it accrues a fixed interest rate annually.
Explanation:The account that can be modeled by exponential growth is Evan's account because it compounds interest. Compound interest involves the exponential growth formula: A = P(1 + r/n)^(nt), where A is the final account balance, P is the principal (initial deposit), r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, Evan's account compounds interest annually, so n=1.
Ethan's account, on the other hand, can be modeled by linear growth. Linear growth is represented by a straight line on a graph, and it involves a constant rate of increase over time. Ethan's account accrues interest at a fixed 8% annually, so the amount in the account increases by the same amount every year.

What is the value of p?
(Geometry Question)
Answer:
p = 92
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angle
p+45 = (p-47)+p
Combine like terms
p+45 = 2p-47
Subtract p from each side
p-p+45 = 2p-p-47
45 = p-47
Add 47 to each side
45+47 = p-47+47
92 = p
