Chardai reads 25% of a book each night that has 280 pages. How many pages will she read
each night?
HINT: twenty-five percent OF 280
Answer:
70 pages
Step-by-step explanation:
Remember that in math, "of" usually means we multiply.
Here, Chardai reads 25% OF a 280-page book each night.
So, we multiply 25% by 280:
25% * 280 = (25/100) * 280 = (1/4) * 280 = 70
The answer is 70 pages.

x/3 + 8= 20 solve for x
Answer:
x=36
Hope this helps! Please mark Brainliest!
Answer:
i would say x= 36.
Step-by-step explanation:
First let's do 20-8 which equals 12. But for this problem we would do 12x3 which would equal 36. Then 36 divided by 3 equals 12 then 12+8=20.
The probability that an event will happen is P(E)=0.34. Find the probability that the event will not happen.
Please I need urgent help
The probability of certainty is 100%=1
If Probability(p)=0.34
then
Probability (p) +cProbability (!p) = 1 where !p is used to denote "not "p
0.34+Probability(!p)=1
Probability(!p)=1−0.34=0.66
The probability that the event will not happen is 0.66.
What is the probability of an event?The probability of an event can be defined as the chance of happening that particular event.
The probability that the event will happen is P(E) = 0.34.
Therefore, the probability that the event will not happen is
= 1 - P(E)
= 1 - 0.34
= 0.66

Teresa makes 9 dollars for each hour of work. Write an equation to represent her total pay p after working h hours
Answer:
P=9h
Step-by-step explanation:
Since Teresa makes 9 dollars for each hour of work, we can say:
9 dollars/1 hour.
Her total pay will be on one side of the equation:
p=
Since we do not know how many hours, we put the variable ‘h’ as it says in the problem in the hour section:
h hours
Every hour, she makes 9 dollars. Every ‘h’ hour, she makes 9xh or 9h dollars since you multiply the amount of money you get each hour by the number of hours. For example, if she worked 2 hours, you multiply 2x9 to get 18 dollars, which is what she earned in 2 hours.
p=9h
A baker puts a chocolate cake in the oven to bake for 30 minutes. Let f(t) = 0.25 + 65 be the temperature of the cake t minutes
after you placed it in the oven. Which of the following statements are true for the given function?
LET ME KNOW ASAP
Answer:
Options (1) and (5)
Step-by-step explanation:
Given function 'f' representing the relation between temperature of the oven after 't' minutes is,
f(t) = 0.25t² + 65
Option (1).
f(0) means that when the cake was placed in the oven, its temperature was 65°.
True.
f(0) = 0 + 65 = 65
Option (2).
To find the temperature after 15 minutes, we need to find 't' when f(t) = 15
False.
We have to find the value of f(15) to find the temperature of the oven after 15 minutes.
Option (3).
Temperature of the cake was 81° F when it was kept in the oven for 8 minutes.
Given statement is False.
It should be represented by,
f(8) = 81
Option (4).
After 10 minutes,the temperature of the cake was 71.25 degree F.
False.
By putting t = 10 in the function,
f(10) = 0.25(10)² + 65
= 25 + 65
= 90° F
Option (5).
The temperature of the cake when the baker takes it out of the oven, can be represented by,
f(30) = 290
True.
f(30) = 0.25(30)² + 65
= 225 + 65
= 290

Tom and Joe are racing towards each other in a game of "chicken." Each boy is riding in a plastic canoe. They are at the local YMCA pool and are starting at a distance of 100 feet apart. Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second. How long will it take for the boys to meet?
Answer:
50 seconds
Step-by-step explanation:
We are told in the question that the distance between them = 100ft
Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second.
The formula for Distance = Speed × Time.
Hence, the Algebraic equation is given as:
6ft/s × t = 4ft/s × t + 100
6t = 4t + 100
6t - 4t = 100
2t = 100
t = 100/2
t = 50 seconds
It will take 50 seconds for the boys to meet.

Jerry planted a pine tree that was 5 feet tall and a maple tree that was 10 feet tall. The pine tree grew 3 feet taller per year and the maple tree grew 2 feet taller per year. Which comparison is described by the inequality below? After x years, the pine tree is taller than the maple tree. After x years, the pine tree is at least as tall as the maple tree. After 3x years, the pine tree is taller than the maple tree was after 2x years. After 3x years, the pine tree is at least as tall as the maple tree was after 2x years.
The initial length of the pine tree=5 feet.
Groth rate of pine tree =3 feet/year.
The initial length of the pine tree =10 feet.
Groth rate of the maple tree =2 feet/year.
After x years, the height of the pine tree= 5+3x feet and
after x years, the height of the maple tree= 10+2x feet.
The inequality for which, after x year, the pine tree is taller than the maple tree is
[tex]5+3x>10+2x[/tex]
[tex]\Rightarrow x>5[/tex] .
The inequality for which, the pine tree is at least as tall as the maple tree is [tex]5+3x\geq10+2x[/tex].
[tex]\Rightarrow x\geq 5[/tex] .
Again, after 3x years, the height of the pine tree= 5+3(3x)=5+9x feet and
after 2x years, the height of the maple tree= 10+2(2x)=10+4x feet.
The inequality for which, after 3x years, the pine tree is taller than the maple tree was after 2x years is
[tex]5+9x>10+4x[/tex]
[tex]\Rightarrow 5x>5[/tex]
[tex]\Rightarrow x>1.[/tex]
The inequality for which, the pine tree is at least as tall as the maple tree is [tex]5+9x\geq10+4x[/tex].
[tex]\Rightarrow 5x\geq5[/tex]
[tex]\Rightarrow x\geq 1.[/tex]

Write an equation of the line that passes through (1, 2) and is perpendicular to the line y = 1/3x+4. An equation of the perpendicular line is
y = ?
Answer:
I'm not sure but I believe its y=-3x+5
Step-by-step explanation:
You start off by finding slope which is -1/m. So 1/1/3=-3. From here you plug in the variables (1,2) and solving. The equation becomes y=-3x+b. From here plug in x and y. So, 2=-3+b. From here add 3 to both sides and you get 5=b. Then just put it together. y= -3x+5
A rectangle has twice the area of a square. The rectangle has the dimensions of 20 inches by 8
inches. What is the perimeter of the square. SHOW WORK PLEASE
Answer:
In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.
