Please help solve, 7th grade work (see image)

This one takes time to type all the math work.

Let me see.

There are two triangles here.

They both have the same area.

A = (1/2)(base)(height) times 2

A = (1/2)(42)(56) times 2

A = 1,176 times 2

A = 2,352 inches^2.

We also have three rectangles. We need to find the area of each rectangle individually.

Area of bottom rectangle = 42 times 72 or 3,024 inches^2.

Area of back rectangle = 56 times 72 or 4,032 inches^2.

Area of slanted rectangle = 70 times 72 0r 5,040 inches^2.

We now add all the areas together to find the total area of the entire figure.

Total Area = 2,352 inches^2 + 3,040 inches^2 + 4,032 inches^2 + 5,040 inches^2

Total area = 14,448 inches^2

Done!

Did you understand what was done here?

Answer:

The answer is A. 8, 9, 10

Answer:

A. 8, 9, 10.

Step-by-step explanation:

Consecutive numbers counting numbers which are 1 greater than the other, therefore:

x + (x + 1) + (x + 2) = 27

(x + x + x) + (1 + 2) = 27

3x + 3 = 27

–3 –3

3x = 24

÷3 ÷3

x = 8.

x = 8 → [ x + (x + 1) + (x + 2) ] =

(8) + (8 + 1) + (8 + 2) = 8 + 9 + 10

Answer:

a) 2

b) 1

c) 4

d) 8

e) 3

f)  9

g) 6

h) 5

Answer:

Step-by-step explanation:

In statistics, about 68 percent of values come in one standard deviation of the mean by using a standard normal model.   Approximately 95% of the data were all within two standard deviations from the mean. Almost all of the data are in the range of three standard deviations of the mean (roughly 99.7%).

The 68-95-99.7 law, also known as the Empirical Rule, is based on this evidence. 68 percent of the data values of a naturally distributed data collection of small children with a mean of 8.2 and a standard deviation of 10.8 would be between -2.2 and 19.0.

Within a mean of 14.1 as well as a standard deviation of 8.2, 68 percent of the data values in a usually distributed data collection of older children would be between 5.9 and 22.3.

However, we cannot conclude that the data is naturally distributed since the real actual data vary from the usual normal curve computed above.

Hence, various measures like either goodness of fit or theory testing, would be used for this.

Answer:

B. the mean is 59 inches

Step-by-step explanation:

if you add the number of inches together you get 413. 413 divided by 7 is 59. that is the mean.

Answer:

B: The mean wingspan is 59 inches.

Step-by-step explanation:

The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.

Step-by-step explanation:

20+2.5v >_ 40

The number of visits Nolan can make to earn his first free movie ticket is 8.

The inequality that represents the information in the question is: 20 + 2.5x ≥ 40.

Where x represents the number of visits to the movie theater.

In order to determine the value of x, take the following steps combine similar terms

2.5x  ≥40 - 20

Add similar terms

2.5x  ≥ 20

Divide both sides by 2.5

x  ≥ 8

Answer:

A) Discount on Cash price. ($9,000 )

B) Cash Price. ($51,000 )

C) Amount Payable. ($51,000 )

D ) Hire Purchase Price ($66,000 )

E ) Difference between the Hire Purchase price and the Cash Price. ($15,000 )

Step-by-step explanation:

The following is the workings:

The GT Missouri marked price = $60,000

If paying cash,

Discount = 15%

(15/ 100 ) x $60,000 = $9,000

Actual Price (less discount) = $60,000 - $9000 = $51,000

If hire purchase,

Firstly, 30% marked price,

= (30/100) x $60,000 = $18,000

Monthly payment = $1000

Period = 4 years = 4 x 12 = 48 months

Total monthly payment,

$1000 x 48 = $48, 000

Therefore, total hire purchase payment

Monthly payment + initial 30% payment

= $18,000 + $48,000 = $66,000

Difference between hire purchase and cash price,

= $66,000 - $51,000 = $15,000
