Answer:
A) 24+24+120+160+200
Step-by-step explanation:
The two ends are 24 (1/2bh= 1/2(8*6)).
One side (the back) is 6x20=120
One side (the bottom) is 8x20=160
One side (the top) is 10x20=200
So the equation is 24+24+120+160+200

Can someone please help with questions 4 and 5 and explain it to me I’ll appreciate!
Answer for number 4:
4. It will take them 3.5 hours on the fourth day.
Alright, so this is a multistep problem.
1. We need to calculate how many miles they have already traveled.
In order to do that, we multiply the number of hours by the average speed on each day.
- On day 1, they drove 5 hours at an average of 70 mph. 5 * 70 = 350, so they drove 350 miles on the first day.
- On day 2, they drove 7 hours at an average of 65 mph. 7 * 65 = 455, so they drove 455 miles on the second day.
- 350 miles + 455 miles = 805 miles, so they've driven 805 miles so far.
2. We need to figure out how far they have left to travel.
They started out with 1,050 miles, so they've got 245 miles left. 1,050 - 805 = 245.
3. We need to figure out how many hours they've got left to drive.
On the third day, they drive at an average speed of 70 mph, and they've got 245 miles left. to find the amount of time they need to drive, we divide the distance by the speed.
245 miles ÷ 70 mph = 3.5 hours. Therefore, it will take them 3.5 hours to reach their friend's home.
Answer For Number 5:
10 gallons of water will leak out in 30 hours.
This question involves unit rates.
1. We need to figure out how much water leaks out per hour.
- Since 7 gallons of water will leak out in 21 hours, we divide the amount of water by the amount of time it took for it to leak out. The answer will be how much water leaks out in an hour.
- 7 gallons ÷ 21 hours = 1/3 gallon of water. Now we have our unit rate. Every hour, 1/3 gallon of water leaks out.
2. We need to figure out how much water will leak out in 30 hours.
- Since we know how much water leaks out in 1 hour, we can easily figure out how much water leaks out in 30 hours. All we need to do is multiply how much water leaks out in one hour by 30!
- 1/3 gallon * 30 hours = 10 gallons of water.
Therefore, 10 gallons of water will leak out in 30 hours.
I hope this helps!

Answer:
they take the same form
Step-by-step explanation:
factor (1 - 1/4 sin ^2 (2A) ) (cos ^ 2 (A) -sin ^2(A))

= - (-1 + ) (sin 2A/2) (1 +) (sin 2A/2) ( cos (A) + sin (A) (cos (A)- sin (A))
= (sin (2A) +sin 2) (sin (2A) -2)/4 = cos ^2(A) = (sin ^2(A)+cos (A) sin (A)) cos ^2(A) +s)

Let's look at our diameters.
[tex]1*10^2^1\\5*10^2^2[/tex]
We want to see how many times greater the diameter of the IC 1101 is than the Milky Way. So, we will divide it's diameter by the diameter of the Milky Way.
[tex]\frac{5*10^2^2}{1*10^2^1} \\[/tex]
We divide the numbers without exponents, giving us 5. Then, we divide the 10s with exponents. When dividing exponents, you subtract the numbers in the exponent to get your result. For example, x³÷x²=x
[tex]\frac{5*10^2^2}{1*10^2^1} = 5*10=50[/tex]
Therefore, your answer is 50.

5. Given that x=-2 is a zero of P(x)=2x3 + x² - 1 1x –10, factor
P(x) as a product of its linear factors. Then find the other zeros.
Step-by-step explanation:
x = -2 is a zero, so x + 2 is a factor of P(x).
Use grouping to factor.
P(x) = 2x³ + x² − 11x − 10
P(x) = 2x³ + 4x² − 3x² − 11x − 10
P(x) = 2x² (x + 2) − (3x² + 11x + 10)
P(x) = 2x² (x + 2) − (x + 2) (3x + 5)
P(x) = (x + 2) (2x² − (3x + 5))
P(x) = (x + 2) (2x² − 3x − 5)
P(x) = (x + 2) (x + 1) (2x − 5)
The other zeros are x = -1 and x = 5/2.
If -1< y< 0, which of the following has the greatest value?
Answer:
[tex]\boxed{\sf B}[/tex]
Step-by-step explanation:
-1 < y < 0
The value of y is negative.
Let’s take the number -0.5.
(-0.5)² = 0.25
1 - (-0.5) = 1.5
1 + (-0.5) = 0.5
2(-0.5) = -1
The greatest value is 1.5.
The answer is 1 - y.
Find the interquartile range for a data set having the five-number summary: 3.5, 12, 19.1, 25.8, 31.8 A. 28.3 B. 13.8 C. 15.6 D. 12.7
Answer:
B. 13.8
Step-by-step explanation:
The five-number summary consists of five items which is usually displayed on a box plot, and can be represented in ascending order.
The five-number summary given: 3.5, 12, 19.1, 25.8, 31.8, represents the following in ascending order:
1. The minimum value = 3.5
2. First quartile (Q1) = 12
3. The median = 19.1
4. Third quartile (Q3) = 25.8
5. The maximum value = 31.8
The interquartile range = Q3 - Q1
Therefore, the interquartile range of the data = 25.8 - 12 = 13.8

solve |x-3|=7 plz help asap I will mark brainliest
Answer:
x=10 or x=-4
Step-by-step explanation:
|x-3|=7
There are two solutions, one positive and one negative
x-3 = 7 and x-3 = -7
Add 3 to all sides
x-3+3 = 7+3 x-3+3 = -7+3
x = 10 x = -4
Well, if we are taking the absolute value, of |x - 3| = 7, then you have a total of two cases. 7 can be either positive or negitive.
Knowing this, we can write out our two cases as:
|x - 3| = 7, or
|x - 3| = -7
Using these two equations, we can solve the equations for our values of x:
First Case:
|x - 3| = 7
x - 3 = 7
x = 10
Second Case:
|x - 3| = -7
x - 3 = -7
x = -4
So, our two cases show us that x can equal -4, or 10.
Mr. Blake's biology class is divided into three secrions. The same test is given to each section. The table above shows both the lowest score and the range of scores on this rest for each section
What is the overall range of all scores in all three sections?
Answer:
25
Step-by-step explanation:
The overall range of all scores in all three sections is 25.
What is Average?In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.
Given:
The range of 3 sections is 28, 25 and 22.
So, the overall range of all scores in all three sections
= (28+ 25+ 22)/ 3
= 75/3
= 25
Hence, the overall range of all scores in all three sections is 25.

TheOriginal tragedy of the commons concern grazing cows and sheep’s and 14 century England, space choose the theme in about the tragedy of the commons that is correct
Answer:
The tragedy of the commons in fourteenth-century England was overcome by the common lands being enclosed and privatized.
Step-by-step explanation:
The Commons tragedy refers to a popular economic narrative that explains why common assets appear to be overused from a social point of view. The story-line is focused on the premise that each person tries to get as much profit as possible from the available resource. As per the question, the land available for grazing was limited and solution can be opted through enforcing regulations, auctioning out a limited number of licenses, or transforming the common good into a private good.

B. 259
6
C. 2 5 9.6
O D.
D. -25 96
Answer:
Option (A),
_____________
-2 | 5 9 -6
Step-by-step explanation:
Division is an algorithm that is used to find the factors of a number. One method of dividing polynomials is through a process of Synthetic division. Synthetic division for polynomials requires that the divisor (an expression that one uses to divide the polynomial) is linear. One will then set the divisor equal to zero and solve for the unknown such as the following,
x + 2 = 0
x = -2
Under the division sign, one will put all of the coefficients of the divided (the number that will be divided) in order of degree. The coefficient of the term with the highest degree is on the leftmost side, the lowest degree is the rightmost. Therefore the problem would appear as the following,
[tex]\frac{5x^2+9x-6}{x+2}[/tex]
= ([tex]5x^2+9x-6[/tex]) ÷ ([tex]x+2[/tex])
_____________
-2 | 5 9 -6
Therefore, the correct choice is option (A).

20x-4y=40
Find the slope of the linear equation
Answer:
the slope is 5
Step-by-step explanation:
Solve for y
20x -4y = 40
Subtract 20x from each side
20x-20x -4y = -20x +40
-4y = -20x+40
Divide each side by -4
-4y/-4 = -20x/-4 +40/-4
y = 5x -10
This is in slope intercept form y = mx+b where m is the slope and b is the y intercept
The slope is 5
Solve for y:
20x - 4y = 40
Subtract 20x to both sides
-4y = 40 - 20x
Divide -4 to everything
y = -10 + 5x
Therefore, the slope is 5
