Answer:
if 1/6 of a roll of paper covers 1/4 of a wall, this means that we will need 4/6 of a roll to cover a whole wall, now the question is asking how many rolls will we need to cover 4 walls, we already know that it takes 4/6 to fill one wall so if we add 4/6+4/6+4/6+4/6 we will get 16/6 or 2 4/6
we will need 16/6 or 2 4/6 of rolls of paper to cover 4 walls
the surface area of a pyramid is 85 square meters the side length of the base is 5 meters what is the slant height
Answer:
6 meters
Step-by-step explanation:
[tex]A=a^2+2a\sqrt{\frac{a^2}{4}+h^2} [/tex]is the formula that you use
h=vertical altitude and
a=side length of the base
[tex]85=5^2+(2*5)\sqrt{\frac{25}{4}+h^2}[/tex]
[tex]85-25=10\sqrt{\frac{25}{4}+h^2}[/tex]
[tex]\frac{60}{10}=\sqrt{\frac{25}{4}+h^2}[/tex]
[tex]6=\sqrt{\frac{25}{4}+h^2}[/tex]
[tex]36=\frac{25}{4}+h^2[/tex]
[tex]36-\frac{25}{4}=h^2[/tex]
[tex]36-6.25=h^2[/tex]
[tex]29.75=h^2[/tex]
Vertical altitude (h) and [tex]\frac{1}{2}a[/tex] and the slant height form a right triangle with the slant height being the hypotenuse
[tex]h^2+(2.5)^2=s^2 [/tex]where s=slant height
[tex]29.75+6.25=s^2[/tex]
[tex]36=s^2[/tex]
s=6 meters
Answer:
slant height = 6 meters
Step-by-step explanation:
surface area of pyramid: 2bs + b²
2*5*s + 5² = 85
10s = 85 - 25
10s = 60
s = 6
The slant height is 6 meters.

On average 113,204 aluminum cans are recycled in a minute. Approximately how many cans will be recycled in 16 days? (Express your answer in scientific notation. ) a. 2. 61 times 10 Superscript 9 aluminum cans b. 4. 35 times 10 Superscript 7 aluminum cans c. 1. 09 times 10 Superscript 8 aluminum cans d. 1. 63 times 10 Superscript 8 aluminum cans.
The number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.
What are Scientific notations?
The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5x 10¹².
Given to us
Average 113,204 aluminum cans are recycled in a minute.
Firstly, in order to find the number of cans that can be recycled in 16 days, we need to find the number of minutes in 16 days. we know that 1 day has 24 hours where each hour has 60 minutes. therefore,
Number of minutes in 16 days = 16 x 24 x 60
Number of minutes in 16 days = 23,040 minutes
As it is given that on an average 113,204 number of cans can be recycled in a minute, therefore,
Total number of can that can be recycled = 113,204 x 23,040
= 2,608,220,160
= 2.6 x 10⁹
Hence, the number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.

The 12th term of the given geometric sequence is equal to -8,388,608.
Given the following sequence:
2, -8, 32, ...What is a geometric sequence?A geometric sequence can be defined as a series of real and natural numbers that are generally calculated by multiplying the next number by the same number each time.
Mathematically, a geometric sequence is given by the expression:

The equatin of line AB is y = 2x + 4. What is the equation of a line parallel to line AB in slope-intercept form that contains the point (3, -2)2
Answer:
Step-by-step explanation:
Parallel lines have the same slope, so if the slope of the given line is 2, the slope of the "new" line is also 2, and the slope-intercept equation becomes:
y = 2x + b.
Here you seem to have a "misprint," as "(3, -2)2 is not a valid expresion.
Supposing that y ou meant (3, -2), then our equation becomes
-2 = 2(3) + b, or -8 = b.
The desired equation is then y = 2x - 8
If this is not what you expected, please focus on your (3, -2)2 and rewrite it properly.

Answer:
10 terms
Step-by-step explanation:
equate the sum formula to 55 and solve for n
[tex]\frac{1}{2}[/tex] n(n + 1) = 55 ( multiply both sides by 2 to clear the fraction )
n(n + 1) = 110 ← distribute parenthesis on left side
n² + n = 110 ( subtract 110 from both sides )
n² + n - 110 = 0 ← in standard form
Consider the factors of the constant term (- 110) which sum to give the coefficient of the n- term (+ 1)
the factors are + 11 and - 10 , since
11 × - 10 = - 110 and 11 - 10 = + 1 , then
(n + 11)(n - 10) = 0 ← in factored form
equate each factor to zero and solve for n
n + 11 = 0 ⇒ n = - 11
n - 10 = 0 ⇒ n = 10
However, n > 0 , then n = 10
number of terms which sum to 55 is 10
