Answer:
b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has a radius of 11 feet
the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380
Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475
Minh and Mikayla are selling wrapping paper for a school fund-raiser. Customers can
buy either packages of folded paper or rolls of paper. Minh sold 6 rolls of paper and 2
packages of folded paper for a total of $44. Mikayla sold 3 rolls of paper and 9 packages
of folded paper for a total of $54. How much does each roll cost? How much does each
package of folded paper cost?
Answer:
Let x=rolls of paper,y=folded paper:
6x+2y=44
3x+9y=54
-------
6x+2y=44
6x+18y=108
16y=108-44=64
y=4
x=6
Thus, a roll of paper cost $6,folded paper was $4 each
Step-by-step explanation:
x = 2 y = 3 z = 4

Which number line correctly shows –0.8 + 0.6?
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.8 to negative 0.2, and then backwards from 0 to negative 0.8.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to negative 0.8 and then from negative 0.8 to negative 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to 0.8 and then from 0.8 to 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.6 to 0.2 and then from 0 to negative 0.6.
Mark this and return
Answer:
Step-by-step explanation:
Since -0.8 is located to the left of origin so when adding any value it will cause it to shift to the right. For example, add 0.1 to 0.8, we get a value of 0.7 shifting the arrow to the right, same goes for 0.2
-0.8 + 0.1 = -0.7
-0.8 + 0.2 = -0.6
-0.8 + 0.4 = -0.4
-0.8 + 0.6 = -0.2
In this way it ends at -0.2

On the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. On the second visit, the kitten had gained 350 grams. On the third visit, the kitten had gained another 300 grams.
What is the percent increase since the first visit in the kitten’s weight rounded to the nearest percent?
PLSS HELPP
Answer:
On first visit, weight =550 g
Weight gained on second visit= 350 g
Weight gained on third visit= 300 g
Present weight=550+350+300= 1200
Weight gained=1200-550=650
Percentage of weight increased
-------->650/550 × 100 = 118.18\%
So the kitten gained 118% weigh

Answer:
2.5x > 25
Step-by-step explanation:
1. 10 + 2.5x > 35
2. 10 + 2.5x - 10 > 35 - 10 (Subtracting 10 from both sides)
3. 2.5x +10 - 10 > 35 - 10 (Group like terms)
4. 2.5x > 35 - 10 (Simplify the arithmetic)
5. 2.5x > 25

Miss Riley's class has 24 students. She has the students in groups. Each group can have no more than 5 students. if every student has to be in groups how many does she have left?
Answer:
if there can be no more than 5 students, then anything less than 5 students will suffice. However we don’t want any left over ones cause we don’t want that one kid sitting alone during lunch so we can simply put 4 into each group.
Step-by-step explanation:
Hope this helped :DDD
Answer:
6 groups, 4 students in each one
Step-by-step explanation:
The factors of 24 include 6 and 4
That means that you can break 24 into those numbers
You are able to put the students up into groups of 6, with 4 students in each
However, you cannot place the students into groups of 4 (with 6 students in each) because no more than 5 students are allowed in each group

Solve for m.
m – 7/8 = 5
Write your answer as a fraction or as a whole or mixed number.
m = ____
Answer:
5 7/8
Step-by-step explanation:
Do the inverse operation.
5 + 7/8 = 5 7/8
Or, do this instead!
Add 7/8 to both sides of the equation. On the side before the equal sign, -78 and +78 cancel out, leaving m all by itself. Bring down the equals sign and we have m = 5 7/8!

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . If a customer paid 120 dollars , how many international minutes did they use ?
Answer: The answer would be 950 international minutes. Only if assuming that this is in one month since the question doesn't give much detail.
Step-by-step explanation:
X would be used to represent the number of months.
25+0.10x=120
0.10x=95
950 international minutes used
Answer:
950
Step-by-step explanation:
An equation to model this scenario would be: y = 0.1x + 25
y would mean the amount of money paid depending on x, which is the number of minutes.
In this problem, we know the amount of money. So we know y is 120.
We can then put 120 into the equation to find x.
120 = 0.1x +25
95 = 0.1x
x = 950
Therefore, x is 950.

What is the perimeter of a rectangle with a length of 15 ft and a width of 32 ft?
A. 47 ft
B. 55 ft
C. 94 ft
D. 480 ft
Answer:
C) 94 ft
Step-by-step explanation:
The perimeter of a rectangle's formula is:
[tex]P = 2l + 2w / P = 2(l+w)[/tex]
I will use the second formula.
We are given the length of 15ft and a width of 32 ft.
[tex]P = 2(15 + 32)\\\rule{150}{0.5}\\P = 2(47)\\\\P = \boxed{94}[/tex]
The answer should be C.
Hope this helps.
Answer:
C. 94 ft.

Answer:
1) 2^9 = 512
2) 2^(3t) = 2^6 for t=2
Step-by-step explanation:
1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...
2^9
Using any of a variety of means, the value of this expression can be found to be ...
2^9 = 512
__
2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:
(2×2×2) × (2×2×2) × (2×2×2)
If this represents the number after 3 hours, then the number after 2 hours is expected to be ...
(2×2×2) × (2×2×2) = 2^6
That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.
Could someone show me the streamline for this problem? The answer is 909, but I'd like to know how
1000-100+10-1
Answer:
1000-100=900,900+10=910,910-1=909
Step-by-step explanation:
Hey there!
1,000 - 100 + 10 - 1
1,000 - 100 = 900
= 900 + 10 - 1
900 + 10 = 910
= 910 - 1
= 909
Thus that’s why 1,000 - 100 + 10 - 1 is most likely equal to 909
