Step-by-step explanation:
Step one:
given data
we are told that Mary can read 22 pages in 30 minutes (0.5 hours)
let us find the number of pages per minute she can read
rate= quantity/time
rate= 22/30
rate=0.73 pages per minute
or
rate= 22/0.5
rate= 44 pages per hour
Step two:
Required
time taken to read 100 pages
t= quantity/rate
t=100/0.73
t=136 pages per minute
or
t= 100/44
t=2.3 pages per hour

Your buddy constructs an angle bisector BD−→− for ∠ABC. She says that m∡ABD and m∡DBC formed by the angle bisector are congruent. Do you think that is always, sometimes or never true for angle bisectors?
Answer:
Always true
Step-by-step explanation:
The definition of an interior or internal angle bisector is the the dividing line segment that splits the angle into two equal angles (parts)
Therefore, given that the segment BD is the bisector of ∠ABC, then the formed angles m∡ABD and m∡DBC are, by definition of bisected ∠ABC, always congruent

Alex is thinking of a number. Twenty less
than one fourth of the number is -45. Find Alex’s number.
i need the equation.
Answer:
¼x - 20 = -45
¼x = -25
x = -100
Step-by-step explanation:
To solve this we can write it out into an equation. Let's use the variable x for the number Alex is thinking of. Then we can take out each information to see what it means mathematically. We need to see what operation is being done.
"twenty less than one fourth of the number" The second part is using mutiplication, as indicated by "of." So we would write a quarter (one fourth) times the number (x). The first part is using subtraction, indicated by "less than." This would be expressed by "- 20"
Putting it together:
¼x - 20
"is -45" this is joining the expression to an equation. So this would simply mean " = -45 " Then our equation is:
¼x - 20 = -45
Now we can solve it.
¼x - 20 = -45
¼x = -25
x = -100
Simplify
-4x+2x2-x2+5-3x
Answer:
9 - 7x - x²
Step-by-step explanation:
-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²
I arranged the like terms together so it is easier to do the calculations.
-4x-3x+2x2+5-x² = -7x+4+5-x²
Simplify.
-7x+4+5-x² = 9-7x-x²
Answer:

what is 90% of 20????
Answer:
18
Step-by-step explanation:
Multiply 20 by 0.90 (that is 90%)
18 is the answer
Hope this helps :)
Answer:
18
Step-by-step explanation:
Hello there. This problem can be easily solved by setting up a ratio.
This would be as follows
[tex]\frac{90percent}{100}[/tex] x [tex]\frac{x}{20 }[/tex]
after solving for x we find that 90% of 20 should be 18.
Hope this helps!

Answer:
- 2x² + x + 42x² + x + 43Step-by-step explanation:
Given functions
r(x) = x + 4s(x) = 2x²Finding (r-s)(x), (r+s)(x), (r*s)(-1)
(r - s)(x) = r(x) - s(x) = x + 4 - 2x² = - 2x² + x + 4(r + s)(x) = r(x) + s(x) = x + 4 + 2x² = 2x² + x + 4(r*s)(-1) = r(-1)*s(-1) = (-1 + 4)*(-1)² = 3*1 = 3Answer:
1. - 2x² + x + 4
2. 2x² + x + 4
3. Answer = 3
Example functions we are given:
r(x) = x + 4
s(x) = 2x²
Now, we Find (r-s)(x), (r+s)(x), (r*s)(-1)
(r - s)(x) = r(x) - s(x) = x + 4 - 2x² = - 2x² + x + 4
(r + s)(x) = r(x) + s(x) = x + 4 + 2x² = 2x² + x + 4
(r*s)(-1) = r(-1)*s(-1) = (-1 + 4)*(-1)² = 3*1 = 3

ermest works in the shipping department loading shipping crates with boxes. Each empty crate weighs 150 lb. How many boxes, each weighing 35 lb, can Ernest put in the crate if the total weight is to be no more then 850 lb?
Max weight of the crate - the empty crate/ by 35 (the weight of the individual boxes)
850-150=700
700 lbs is the remaining weight available that can be filled with 35 lb boxes, to find out the number of boxes that can be added to the crate, divide 700 by 35.
700/35 = 20
Ernest can put in 20 boxes in the crate.

Carlos bought 4 yards of packing tape. He used 1 3/5 yards on a package for his father and 2 1/3 for a package. How many yards of packing tape does Carlos have left (only write the fraction with no words as your answer)?
Answer:
1/15 yards
Step-by-step explanation:
Total yards of packing tape = 4 yards
Yards used for his father = 1 3/5 yards
Yards used for another package = 2 1/3 yards
Total yards used = 1 3/5 + 2 1/3
= 8/5 + 7/3
= 24+35/15
= 59/15 yards
How many yards of packing tape does Carlos have left
Total yards left = Total yards of packing tape - Total yards used
= 4 - 59/15
= 60-59/15
= 1/15
Total yards left = 1/15 yards

What is the inverse of the function g(x)=5(x-2)g(x)=5(x−2)g, left parenthesis, x, right parenthesis, equals, 5, left parenthesis, x, minus, 2, right parenthesis
Answer:
(x+10)/5
Step-by-step explanation:
Given the function
g(x) = 5(x-2)
Open the parenthesis
g(x) = 5x-10
To find the inverse we need to follow the steps;
Step 1; make y as g(x)
y = 5x-10
Step 2; replace y with x;
x = 5y - 10
Step 3; make y the subject of the formula;
x = 5y-10
5y = x+10
y = (x+10)/5
Step 4: substitute y as g^(-1)(x)
g^(-1)(x) = (x+10)/5
Hence the inverse of the function is (x+10)/5
Answer: x+10/5

Jada’s bike wheels have a diameter of 20 inches. How far does she travel if the wheels rotate 37 times?
A. 2,549 inches
B. 2,324 inches
C. 2,347 inches
D. 2,515 inches
(SHOW YOUR WORK FOR A BRAINLIEST)
Answer:
C
Step-by-step explanation:
Answer:
B. 2,324 inches
Step-by-step explanation:
You need to find the circumference of the bike wheels first so that you know how much she would travel if her wheels rotated 1 time. Circumference of circle = pi × d
1 time = 20pi
37 times = 20pi × 37
= 740pi
= 2324.778564...inches
The diameter of a cartwheel is 2.1 m. Find the distance travelled when it completes 100 revolutions.
You need to find the circumference of the cartwheels first so that you know how much it would travel if her wheels revoluted 1 time. Circumference of circle = pi × d
1 revolution = 2.1pi
100 revolutions = 2.1pi × 100
= 210pi
= 659.7344573...m
The diameter of a circular park is 98 m. Find the cost of fencing it at $4 per meter.
You need to find the circumference of the park first so that you know how much it would cost. Circumference of circle = pi × d
Circumference of park = 98pi
Cost of fencing = 4 × 98pi
= 392pi
= $1231.50
≈ $1232.00

Please give me an explanation too I need help Solve for y: 2x-y=3
Answer:
y = 2x -3
Step-by-step explanation:
to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3
Answer:
y=2x-3
Step-by-step explanation:
2x-y=3
-2x on both sides of the equal sign which leaves you with -y=-2x+3
divide both sides by negative 1
y=2x-3
