If 12% of the air leaks out of Brian's bicycle tire every day, what percent of the air will be left after 2 days? After a week? Round your percents to 2 decimal places.
Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%
A canister holds 3 blue pens, 4 black pens, 2 red pens, and 6 pencils. The simplified ratio of ALL the pens to pencils is
Answer:
The simplified ratio of ALL the pens to pencils is
= 3:2
Step-by-step explanation:
A canister holds 3 blue pens, 4 black pens, 2 red pens, and 6 pencils.
Step 1
Sum of all the pens is:
Blue pens + Black pens + Red pens
= 3 + 4 + 2
= 9 pens
Number of pencils = 6 pencils
Step 2
The simplified ratio of ALL the pens to pencils is
Pens : Pencils
= 9 : 6
= 3:2
How to do surface area- cylinder worksheet
Answer:
to find surface area of cylinder
A=2πrh+2πr²
Step-by-step explanation:
b) Here are the first four terms of another sequence.
7
11 15 19
Write an expression for the nth term of this sequence.
Answer:
[tex]a_{n}[/tex] = 4n + 3
Step-by-step explanation:
There is a common difference between consecutive terms, that is
11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4 , then
[tex]a_{n}[/tex] = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

Choose the solution to this inequality.
The answer is c because 8-4is 4 and 3 (dominator) stays the same
need some help with this
Answer:
c. infinitely many solution
Answer: C
Step-by-step explanation:
5 + -2x = 4 + -2x + 4 + x
Reorder the terms:
5 + -2x = 4 + 4 + -2x + x
Combine like terms: 4 + 4 = 8
5 + -2x = 8 + -2x + x
Combine like terms: -2x + x = -1x
5 + -2x = 8 + -1x
Solving
5 + -2x = 8 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
5 + -2x + x = 8 + -1x + x
Combine like terms: -2x + x = -1x
5 + -1x = 8 + -1x + x
Combine like terms: -1x + x = 0
5 + -1x = 8 + 0
5 + -1x = 8
Add '-5' to each side of the equation.
5 + -5 + -1x = 8 + -5
Combine like terms: 5 + -5 = 0
0 + -1x = 8 + -5
-1x = 8 + -5
Combine like terms: 8 + -5 = 3
-1x = 3
Divide each side by '-1'.
x = -3
Simplifying
x = -3
What is the vertex for the following quadratic?
f(x)= 2x^2-12x+16
Answer:
(3, -2)
Step-by-step explanation:
To find the vertex, put the equation into vertex form by completing the square
2(x^2 - 6x) + 16 [pulling out the 2]
2(x^2 - 6x + 9) - 18 + 16 [completing the square, you subtracted 2*9 = 18 so you also add 18]
2(x - 3)^2 - 2 [simplify the equation]
vertex is (3, -2)

If x and y vary inversely and x = 1 when y = 11, find x when y = 5.5.
Answer:
x = 2.
Step-by-step explanation:
y = k/x
11 = k/1
so k = 11
y = 11/x
When y = 5.5:
5.5 = 11/ x
x = 11/5.5
= 2.
The values of x and y vary inversely, if the value of y is 5.5 then the value of x will be equal to 2.
What is an arithmetic operation?The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included is the study of integers, especially the order of operations, which is essential for all other aspects of mathematics, notably algebra, information management, and geometry.
As per the information provided in the question,
y = k/x
11 = k/1
k = 11
y = 11/x
If y = 5.5,
5.5 = 11/ x
x = 11/5.5
x = 2.

[tex]-\frac{1}{2} *(-\frac{5}{6} )+(-\frac{1}{2} )*\frac{1}{3} \\=\frac{5}{12} -\frac{1}{6} \\=\frac{5}{12} -\frac{2}{12} \\=\frac{3}{12} \\\frac{1}{4}[/tex]
Answer:
it's 5/12 + 1/3
Step-by-step explanation:
you would multiply the -5/6 by -1/2 to get 5/12 since the negative would cancel out
so 5/12 + 1/3 would be the answer.
Also this question doesn't make any sense since you are supposed to simplify the parentheses first.

The dot plot shows a random sample of the number of fish caught and released by 30 participants during a two-day fishing derby. Two dot plots show the number of fish caught on days 1 and 2. The dot plot for day 1 has dots as follows: 3 above 1, 6 above 2, 6 above 3, 6 above 4, 6 above 6, and 3 above 6. The dot plot for day 2 has dots as follows: 3 above 1, 3 above 2, 4 above 3, 6 above 4, 7 above 5, and 7 above 6. Use the mean value of each data set to make an inference about the number of fish caught each day. On average, most participants caught and released 5 or more fish. More participants caught 6 fish than any other number. The same participants who caught and released 1 fish the first day caught and released 1 fish the second day. On average, participants caught and released more fish on Day 2.
