Answer:
2 1/6
Step-by-step explanation:
How we calculate this is make the two fractions denominators the same so we can make them both 6.
for the 3 we times it by 2 and 2 by 3.
so our 2 fractions are now 2 4/6 and 3/6 Now
so if we take away 3 of 4 we get 1 so 2 and 4/6 is now 2 and 1/6
Meaning the 2 1/6 is what she has left so if she gives that all to her brother he gets that and there's your answer.
Hope it helps have a great afternoon:)
How are parallelograms and rectangles similar and how are they different?.
A 499
B 498
C 898
D 500
Answer:
498
Step-by-step explanation:
We will need to use the Pythagorean Theorem.
A^2 + B^2 = C^2
45^2 + B^2 = 500^2
Subtract 45^2
B^2 = 500^2 - 45^2
Simplify
B^2 = 247,975
Take square root so B is alone
B = 497.9708
Round
B = 498

A school has 3 tons of gravel to be
spread over the playground. The
members of the landscaping crew
can move 80 pounds of gravel in each
wheelbarrow load.
How many wheelbarrow loads will it take to move all the gravel?
Using proportions, it is found that it will take 75 loads to move all the gravel.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In one load, they mode 80 pounds. How many loads are needed to move 3 tons = 3 x 2000 = 6000 pounds? The rule of three is given as follows:
1 load - 80 pounds
x loads - 6000 pounds
Applying cross multiplication:
80x = 6000
x = 6000/80
x = 75.
It will take 75 loads to move all the gravel.

2/5x + 4 = 1/5x + 8 what does x equal
Answer:
x=20
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
2/5x + 4 = 1/5x + 8
(subtract 1/5x from both sides)
1/5x + 4 = 8
(subtract 4 from sides)
1/5x = 4
(multiply by 5 from both sides of the equation to isolate x)
x = 20

If two polygons ___________, then they have the same area.
are congruent
have the same number of sides
have the same number of angles
are similar
Answer:
are congruent
Step-by-step explanation:
If two polygons are congruent, then they have the same area.
Two polygons are congruent if their corresponding sides and angles are congruent. Note: Two sides are congruent if they have the same length and angles are congruent if they have the same measure. We indicate that angles are congruent by putting the same number of slash marks through each angle.

What is the approximate area of the shaded region under the standard normal curve below? Use the portion of the standard normal table to help answer the question. A normal curve with a peak at 0 is shown. The area under the curve shaded is negative 1 to positive 2. Z Probability 0. 00 0. 5000 1. 00 0. 8413 2. 00 0. 9772 3. 00 0. 9987 0. 16 0. 68 0. 81 0. 84.
The area under the curve shaded is -1 to 2 is 13.59%.
The z score is a measure used in statistic to determine by how much standard deviations the raw score is above or below the mean.
If the raw score is greater than the mean then the z score is positive but if the raw score is less than the mean then the z score is negative.
What is the formula for the z score?
The formula of z score
[tex]Z=\frac{x-\mu}{\sigma}[/tex]
[tex]\mu=mean[/tex]
[tex]\sigma=standard deviation[/tex]
x=raw score
From the normal distribution table,
Area between z = -2 and z =-1 is given by
P(-2 < z < -1) implies that P(z < -2) - P(z < -1) that is
P(z < -2) - P(z < -1) = 0.1587 - 0.0228
P(z < -2) - P(z < -1) = 0.1359
P(z < -2) - P(z < -1) = 13.59%
Therefore we get the area under the curve shaded is -1 to 2 is 13.59%.

Answer:
E, 3/2
Step-by-step explanation:
First, say that the numerator is 2^2001 * 3^2001 * 3^2, so that the powers will align. Then, we can combine 2^2001 and 3^2001 for 6^2001. If we ignore the 3^2, we get 6^2001/6^2002, which simplifies to 1/6. If we multiply 9 (which is 3^2) to 1/6, we get 9/6=3/2. This is a pretty tough question. Hopefully this helps!

Write the equation of a line through points (5, 5) and (1, 0) in point-slope form.
Help soon pls :)
Answer:
Step-by-step explanation:
Find the slope of the line between (5,5)and (1,0) using m=(y2-y1)/(x2-x1)
which is the change of y over the change of x.
m=5/4
Use the slope 5/4 and a given point (5,5) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=(y2-y1)/(x2-x1)
y-5=5/4*(x-5)
Simplify the equation and keep it in point-slope form y-5=5/4*(x-5)
Solve for y.
y=5x/4-5/4
Reorder terms.
y=5/4 x-5/4
List the equation in different forms.
Slope-intercept form: y=5/4 x-5/4
Point-slope form: y-5=5/4*(x-5)

A school sells pizza slices at the concession stand during each sporting event. The school sells a mean of
200 slices per event with a standard deviation of 25 slices.
The school spends $160 of fixed costs to buy the pizza before the event and earns a revenue of $2 per
slice. They calculate their profit per event according to this formula:
profit
(total revenue) – (total costs]
What will be the mean and standard deviation of the distribution of profit per event?
Answer:
μ = $240
σ = $50
Step-by-step explanation:
Profit is revenue minus cost:
P = R – C
The revenue is $2 times the number of slices sold, and the cost is $160.
P = 2x – 160
The average profit is:
μ = 2(200) – 160
μ = 240
The standard deviation is:
σ = 2(25)
σ = 50

Jake has a container in the shape of a rectangular prism. The base of the container is 30 centimeters long and 20 centimeters wide. Jake pours 0.5 gallons of water into the container. How high, in centimeters, will the water reach in the container? Note that 1 gallon is approximately equal to 3.8 liters and 1cm3 of volume can hold 1 milliliter of water.
Answer:
3.16cmStep-by-step explanation:
Given that
1gallon=3.8liters
0.5gallon=x
x=0.5*3.8
x=1.9liters
we know that 1liter is 1000cm^3
1.9liter is x
x=1900cm^3
Now we have the volume of water poured in cm^3
the volume of a rectangular prism is
volume=l*w*h
1900=30*20*h
1900=600h
h=1900/600
h= 3.16cm

Answer:
For class A, the test scores were closer togther so that means more students most likely scored the smae score mutiple times. I think this because the box on the box plot is not spread out like class B.
For class B, the scores varied more so the box plot has to be spread out over more values. Because of the box plot, we can see that Class B had the highest test score compared to class A.

A Ferris wheel at Kone Island has a diameter of 63 feet.
Which equation can be used to find its circumference, Cin feet?
diameter 63 feet
O C = 63 x II
O C = 31 x II
O C = 2 x II x 63
O C = 2 x II x 31
The circumference of the Ferris wheel is the product of the diameter and [tex]\pi[/tex]
The circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]
How to determine the circumference equationThe circumference of a circle, when the diameter is given is calculated using the following equation
C = [tex]\pi[/tex]d
The diameter of the Ferris wheel is given as:
d = 63 feet.
So, we have;
C = [tex]\pi[/tex] * 63
Rewrite as:
C =63 * [tex]\pi[/tex]
Hence, the circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]
