Answer:
B 20r
Step-by-step explanation:
r² + + 100
r² = (r ) ( ) signs are all positive. 100 = (10) (10) last number. so
(r + 10)(r + 10)
r(r+ 10) + 10(r + 10)
r² + 10r + 10r + 100
r² + 20r + 100

Find the surface area of the following cylinder.
Round your answer to the nearest square centimeter.
The surface area, to the nearest square centimeter, of the given cylinder is: 182 cm²
Recall:
Surface area of a cylinder = 2πrh + 2πr²From the diagram given, we have:
radius (r) = half of diameter = 10/2 = 5 cmheight (h) = 0.8 cmSubstitute each value into the surface area formula for a cylinder.
Thus:Surface area = 2(π)(5)(0.8) + 2(π)(5²)
Surface area = 182.212
Therefore, the surface area, to the nearest square centimeter, of the given cylinder is: 182 cm²

Answer: B. k = 12.1.
C. k = 13.0.
D. k = 19.9.
Step-by-step explanation: Which values of k are solutions to the inequality k>12 are B. k = 12.1 , C. k = 13.0 , and D. k = 19.9 because it literally says k>12 so every value of k that's solutions to the inequality k>12 have to be greater than 12.

Johnny's home is m miles from school. Johnny runs to school at a speed of 8 mph and then walks home from school at half that speed. Suppose it take johnny 15 longer to walk to home than to run to school. Write an equation that shows this relationship.
Answer:
first we know the speed from home to school is 8mph and from school to home is half that speed so 4 miles per hour
now,
from home to school it takes: m/8 hours
and from school to home m/4 hours
we can pass it to minutes multiplying by 60
so:
from home to school it takes: m*7.5 minutes
and from school to home m*15 minutes
and now the relations between these two amount of minutes is that takes 15 more from school to home so:
7.5m+17

What is the value of the expression 5(6/12-1/4) + 0.5
Answer:
5/8
Step-by-step explanation:
First you need to reduce the fractions then you choose a common denominator to calculate:6/12=1/2 then you see the you see 1/4 can be a common denominator so you equal 1/2 to the denominator by 4, which means multiplying 2 by both the numerator and denominator, we get 2/4 after that you add and subtract in parentheses and you will get 1/4 then you multiply by 5 to get 5/4 the finally you have to plus 0,5 you will get 7/4 done.

Safe Combination. The author owns a safe in which he stores all of his great ideas for the
next edition of this book. The safe combination consists of four numbers between 0 and 99. If
another author breaks in and tries to steal these ideas, what is the probability that he or she will
get the correct combination on the first attempt? Assume that the numbers are randomly
selected. Given the number of possibilities, does it seem feasible to try opening the safe by
making random guesses for the combination?
Answer: 1/96059601
Don't break in
Step-by-step explanation:
First we need to find how many combinations there are.
We can find that by multiplying the four different number of options which in this case are all 99.
99 * 99 * 99 * 99
= 96059601
There are 96059601 different combinations and one correct combination.
So, the chance of them getting it is 1/96059601
It is definitely not a nice number so probably don't try and break in.

Answer:
a) 1,144 rad/min
b) 182.1 rev/min
Step-by-step explanation:
d= 24 inches
radius = 24/2 or 12 inches
speed = 13mi/h
need to convert speed to inches/min
v = Θ * r
1 mile = 63360 inches, and 1 hour = 60 min
13 mi * (63360 in / mi)
= 823680 in / (1 hr * 60 min / hr)
=13728 in/min
Now go back to the equation
13728 in / min = ω * 12 in
13728 /12 = Θ
1,144 rad/min
b) 1 revolution = 2π
w= Θ/2π
w= 1,144rad/ min/2pi rad
w= 182.1 rev/min

Answer: y = -3x - 6
Step-by-step explanation:
One way to write a linear equation is with slope-intercept form. Slope-intercept form is y = mx + b, where m is the slope, and b is the y-intercept.
Thus, the equation is y = -3x - 6
Hope it helps :) and let me know if you are confused anywhere.
Answer:
y = -3x - 6
Step-by-step explanation:
Insert the information into the slope-intercept form equation:
y = mx + b
m = slopeb = y-intercept valueIn this instance, the slope is -3 and the y-intercept value is -6. Therefore, the equation of the line is y = -3x - 6
Hamid needs to find the height of a parallelogram. The base is 3 inches long and the area is 30 square inches. What is the height?
Step 2 of 2: Finally, solve the problem by substituting in the appropriate values. (Round your answer to 2 decimal places if necessary.)
Answer:
the height is 10 inches
Step-by-step explanation:
area of a parallelogram is base times height
3h=30
divide both sides by 3
h=10
Answer:
area is base times height the base us 3 inches the area is 30 inches 3 times 10 is 30 so 10 is the height

The governor of state A earns $51,615 more than the governor of state B. If the total of their salaries is $291,335, find the salaries of each.
Answer:
A = $171,475, B = $119,860
Step-by-step explanation:
A represents the salary of the governor of state A.
B represents the salary of the governor of state B.
A is $51615 larger than B, so you get the equation:
A = B + 51615
The total of the two salaries is $291335, so you can the second equation:
A + B = 291335
Using the first equation, substitute the quantity (B + 51615) for A in the second equation.
(B + 51615) + B = 291335
2B + 51615 = 291335
2B = 239720
B = 119860
Plug this value of B back into either of the equations.
A = B + 51615 = 119860 + 51615 = 171475
