Sports companies cover the surface of a soccer ball with waterproof spray to prevent it from getting water logged. The radius of a soccer ball is 11cm. The formula to calculate Surface Area of a ball is SA = 4πr2 S A = 4 π r 2 . How much surface do they need to cover with the spray?
Answer:
310.73cm^2Step-by-step explanation:
The expression for the total surface area is
SA=4πr^2
given that r=11cm
we want to substitute the value of r to solve for the area
SA=4πr^2
SA=4*3.142*(11)^2
SA=2.568*11^2
SA=2.568*121
SA=310.728
Therefore they need to cover a surface of 310.73cm^2

A restaurant manager states the number of customers that enter the restaurant is equal to 4
times the number of people that buy a hotdog from the hotdog cart plus 11. The manager also
states that the number of customers that enter their restaurant is equal to 1 times the number of
people that buy a hotdog from the hotdog cart plus 38. What number of people buying a hotdog
from the hotdog cart across the street makes the equation 4x + 11 = 1x + 38 true? Round
your answer to the nearest whole number.
Answer:
9
Step-by-step explanation:
No of customers that enter the restaurant is equal to 4 times the number of people that buy a hotdog from the hotdog cart plus 11.
The number of customers that enter their restaurant is equal to 1 times the number of people that buy a hotdog from the hotdog cart plus 38.
The equation that shows the given condition,
4x + 11 = 1x + 38
x is the no of people
Taking the like terms,
4x-1x=38-11
3x=27
x = 9
So, there are 9 people buying a hotdog from the hotdog cart.

The perimeter of a worksheet is 48 inches. The worksheet is 14 inches long. How tall is it?
inches
Answer: 10 inches
Step-by-step explanation:
1. multiply 14 by 2 to get 28.
2. Subtract 28 from 48 to get 20
3. Divide 20 by 2 to get 10
your answer is 10
Answer: 10 inches
Step-by-step explanation:
a worksheet is usually a rectangle
the formula for the perimeter of a rectangle is 2x + 2y
Lets say that x = the length and y = the height
it already gives you x = 14, so plug everything in to find y
P = 2x + 2y
48 = 2(14) + 2y
48 = 28 + 2y plug in x = 14 and multiply
20 = 2y subtract 28 from both sides to get this
y = 10 then divide both sides by 2 to get the answer

2 step equations: solve the equation below:
m/5+9=11
Answer:
m=10
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
m/5+9-(11)=0
m
Simplify —
5
m
(— + 9) - 11 = 0
5
Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
9 9 • 5
9 = — = —————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
m + 9 • 5 m + 45
————————— = ——————
5 5
(m + 45)
———————— - 11 = 0
5
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
11 11 • 5
11 = —— = ——————
1 5
Adding up the two equivalent fractions
(m+45) - (11 • 5) m - 10
————————————————— = ——————
5 5
m - 10
—————— = 0
5
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
m-10
———— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
m-10 = 0
Solve : m-10 = 0
Add 10 to both sides of the equation :
m = 10
m = 10
At the grocery store, Jerry spent $24.75 for 3 pounds of chicken and 3 pounds of cheese. The cheese cost $4.50 per pound. What was the cost of the chicken
per pound?
Answer:
$3.75 per pound of chicken
Step-by-step explanation:
Price of 3 pounds of cheese $ 4.50x3= $13.50
$24.75-$13.50 = $11.25 (price of 3 pounds of chicken)
Chicken : $11.25/ 3 = $3.75 per pound
$11.25 + $13.50 = $24.75

A. The function is negative when x<0 and also when x>0
B.the function is never negative
C.the function is negative when x>0
D. The function is negative when x<0
Using function concepts, it is found that the correct option is given by:
D. The function is negative when x<0
How the sign of a function is determined?If the graph is above the x-axis, it is positive.If the graph is below the x-axis, it is negative.In this problem, the graph of the function is the red line, and:
For values of x < 0, the function is below the x-axis, hence it is negative.For values of x > 0, the function is above the x-axis, hence it is positive.Thus, option D is correct.

The function f(t) = |98.6-x|, represents a persons's variance from normal body temperature, where x represents a person's current body temperature in degrees Fahrenheit. Medical professionals say healthy individuals should have a variance of no more than 0.5 degrees Fahrenheit.
Answer:
98.1°F ≤ x ≤ 99.1°F
Step-by-step explanation:
Given the function:
f(x) = |98.6 - x|
Variance = 0.5
98.6°F - x = ± 0.5
Lower bound :
98.6 - 0.5 ≤ x
98.1 ≤ x
Upper bound :
x ≤ 98.6 + 0.5
x ≤ 99.1
Hence,
98.1°F ≤ x ≤ 99.1°F

Max and his brother exercise together. Max does half as many sit-ups as his brother does during a workout. If Max's brother does between 100 and 150 sit-ups, which expression describes s, the number of sit-ups that Max does?
A. 0 ≤ s ≤ 50
B. 50 ≤ s≤ 75
C. 100 ≤ s ≤ 150
D. 200 ≤ s ≤ 300
Answer:C is the correct answer,
Step-by-step explanation:
50 ≤ s≤ 75 describes the number of sit-ups that Max does so option (B) will be correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Max does "s" number of sit-ups then max brother will do "2s".
Now,
Given that,
Max's brother does between 100 and 150 sit-ups
So,
100 ≤ 2s ≤ 150
Divide by 2 into both sides
50 ≤ s ≤ 75
Hence " 50 ≤ s≤ 75 describes the number of sit-ups that Max does".

What is the purpose of the AutoSum feature in Microsoft® Excel? A. To automatically add all numbers in all cells in a workbook B. To add a list of numbers in a spreadsheet C. To put a list of numbers in order before finding the sum D. To estimate the total of a list of numbers
Answer:
B. To add a list of numbers in a spreadsheet
Step-by-step explanation:
AutoSum feature in Microsoft Excel is used to automatically sum up a range of numbers within a horizontal row or vertical column without having to input a formula.
When a range of numbers are selected within a row or column, clicking on AutoSum will sum up the numbers in the adjacent empty cell. For example, if you wanted to add the values of cells between B1 and B10, highlight cells B1 through B10 and click the AutoSum button . The sum of B1 to B10 will be given in B11.
In Excel 2010 and later, the AutoSum feature is on the Home tab, in the Editing section.

The quotient of a number and twelve is the sum of eight and the number.
Answer: n/12=8+n
Answer:
Step-by-step explanation:
12(n/12 = 8 + n)
n = 96 + 12n
-11n = 96
n = -96/11
Answer:
-96/11 or -8 8/11
Step-by-step explanation:
For this, create an equation, x/12=x+8.
Any number without a denominator has a denominator of 1, so x/12=(x+8)/1.
Now, cross multiply to get 1*x=12(x+8).
Simplify that to x=12x+96.
Subtract 12x from both sides, and you have -11x=96.
Divide by -11, and x=-96/11.
4) After solving a rational equation you must check your solutions in the
original equation. Why? *
To make sure the value does not make the numerator 0.
O
To make sure the value does not make the denominator 1.
O To make sure the value does not make the numerator negative.
To make sure the value does not make the denominator 0.
Answer: D) To make sure the value does not make the denominator 0.
We cannot divide by zero. Something like 1/0 is undefined. So it's important to check all potential solutions to make sure you don't get 0 in the denominator.
