How do u work out
65% of 8700
First off, you have to make 65 % into an actual number, which is 0.65 (every time you want to convert percentages into numbers, you have to divide that by 100)
Now
0.65 * 8700 = 5655
Answer: 5655

Answer:
[tex]g(x) = 5x^2[/tex]
Step-by-step explanation:
In the equation x^2, when x = 1, y = 1. But in g(x), when x is 1, y is 5. Since g(x) is a scaled version of x^2, we can conclude that g(x) is 5 times x^2.
Therefore, [tex]g(x) = 5x^2[/tex].

I'm having trouble finding the x-intercepts AND the y-intercept, could some help and explain there work?? :)))) thank you!!
f(x)= x^3 - 4x^2 - 11x + 30
Hello,
[tex]f(x)=x^3-4x^2-11x+30 \\\\f(0)=30[/tex]
so y-intercept is (0,30)
The product of the roots are -30 = 2 * 5 * -3, and the sum is 4 = 2 + 5 - 3 , so we can factorise
[tex]f(x)=x^3-4x^2-11x+30 \\\\f(x)=0 \\\\<=> x^3-4x^2-11x+30=(x+3)(x-2)(x-5)=0\\\\<=> x=-3 \ or \ x=2 \ or \ x=5[/tex]
x-intercepts are (-3,0) (2,0) and (5,0)

Answer:
The answer your looking for is (most likely) C.
Step-by-step explanation:
If you had a mirror on the y-axis, the reflection of the pre-image triangle would be the image. The y-axis, called the line of reflection, is the line of symmetry for the two triangles. Triangle 1 is called the pre-image, and the reflected triangle is called the image.

Find the complement of ∠DEF.
Answer: Choice B) 14 degrees
Explanation:
Complementary angles add to 90 degrees
This means the answer we're after is 90 - (angle DEF) = 90-76 = 14
Answer is B
Complement means two angles that have the sum of 90°
90 - 76 = 14
so that would mean 14° is the correct answer

How to find the perimeter and area of 7.7m, 2.8m, 9.7m, 4
Answer: perimeter = 26.8
area = 49.16
Step-by-step explanation:
perimeter:
Rectangle one:
add 9.7 + 9.7 + 4 + 4 because there is 4 sides = 27.4
Rectangle 2:
2.8 + 2.8 + 3.7 +3.7 = 13
Add them together: 27.4 + 13 = 40.4
area :
rectangle one:
multiply 4 x 9.7 = 38.8
rectangle two:
multiply 3.7 x 2.8 = 10.36
add them together: 10.36 + 38.8 = 49.16
a square room has a floor area of "100" square feet. the height of the room is 6 feet what is the area of one wall
Answer:
Its 60
Step-by-step explanation: 10x10=100 so 10x6=60
Did that help you???
The area of one wall of the square room is 60 sq. feet.
What is the area of a square?The area of a square is the square of its side.
If the length of a side of a square is a unit, then its area is
Area = a² sq. units.
How to solve the question?In the question, we are informed that a square room has a floor area of 100 sq. feet, and its height is 6 feet.
We are asked to find the area of one wall.
The floor of the room is given a square. We let the length of the side of that square be 'a' units.
Then, its area is a² sq. units.
We are given that the area of the floor is 100 sq. feet.
So, we can write the equation as:
a² = 100 sq. feet,
or, a = 10 feet.
The height of the room is given as 6 feet.
Therefore, the area of a wall is 10*6 sq. feet = 60 sq. feet.
As the floor is rectangular in shape, with dimensions 10 and 6.
Therefore, the area of one wall of the square room is 60 sq. feet.

two years ago the cats tim and tom were toghether 15 years old.Now tom is 13 years old.In how many years will tim be 9 years old?
Answer:
3 years
Step-by-step explanation:
As with many age problems, you can reason it without equations. If Tom is 13 now, 2 years ago he was 11. If the total age of the two cats at that time was 15, then Tim was 15 -11 = 4.
That means Tim is now 4+2 = 6, so will be 9 in 3 years.
_____
Additional comment
If you want to write equations, there are several ways you can do it. We often like to use variables to represent the current age. We can assign ...
x = Tim's current age; y = Tom's current age.
The sum of their ages 2 years ago was ...
(x -2) +(y -2) = 15
Tom's current age is 13, so we have y=13. Using that in the equation gives ...
x -2 +13 -2 = 15
x = 6 . . . . . . . . . . subtract 9, collect terms
That's Tim's current age, so Tim will be 9 years old in 3 years.

What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
The distance between City A and City B is 200 miles. A length of 2.1 feet represents this distance on a certain wall map. Then the scale factor is given as,
Scale factor = 200 / 2.1 miles per foot
City C and City D are 3.15 feet apart on this map. Then the actual distance is given as,
Distance = 3.15 x 200 / 2.1
Distance = 1.5 x 200
Distance = 300 miles
The actual distance between City C and City D will be 300 miles.

Avoiding an accident when driving can depend on reaction time. That time, measured in seconds from the moment the driver see danger until they step on the brake pedal, can be described by the Normal model with a mean of 1.5 seconds and a standard deviation of 0.18 seconds.
Note that this scenario is talking about a population distribution. There is no discussion of a sample or sample size. Therefore, you do not need to adjust the standard deviation that is given before using the normalcdf and invNorm commands.
a) What percent of drivers have a reaction time greater than 1.8 seconds?
Give the command and values you used as a way of showing your work:
Give your final answer rounded to 2 decimal places:
b) Describe the reaction time of the slowest 10% of all drivers? (Hint: The slower a person reacts, the higher their reaction time so this is looking at the right tail of the distribution)
Give the command and values you used as a way of showing your work:
Give your final answer rounded to 2 decimal places:
Using the normal distribution, it is found that:
a) 4.75% of drivers have a reaction time greater than 1.8 seconds.
b) The reaction time is of at least 1.73 seconds.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively:
[tex]\mu = 1.5, \sigma = 0.18[/tex]
Item a:
The proportion is one subtracted by the p-value of Z when X = 1.8, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1.8 - 1.5}{0.18}[/tex]
[tex]Z = 1.67[/tex]
[tex]Z = 1.67[/tex] has a p-value of 0.9525.
1 - 0.9525 = 0.0475 = 4.75%.
4.75% of drivers have a reaction time greater than 1.8 seconds.
Item b:
The reaction time is of at least X seconds, in which X is the 90th percentile, that is, X when Z = 1.28, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.28 = \frac{X - 1.5}{0.18}[/tex]
[tex]X - 1.5 = 1.28(0.18)[/tex]
[tex]X = 1.73[/tex]
The reaction time is of at least 1.73 seconds.

For the crazy pizza portfolio I just need the formulas to prove that my pizza can fit inside the box I already have A=pi r2 now I just need the rest
To prove that the pizza fits inside the box we need the formula for the area of a square, to identify the area of the box and to know if the pizza fits inside the box.
How to calculate the area of the box (area of a square)?To calculate the area of a square we must apply the following formula:
Length of square × base of square = area of square ²According to the above, if we have a pizza with a radius of 30cm, its area would be:
A = 3.14 × 15²A = 706.5 cm²So we would need a box with a side length of at least 30cm. Its area would be:
30cm × 30cm = 900cm²
So for a 706.5cm² pizza, we need a 900cm² box.
