Mathematics

Gemiola [76]3 years ago

Answer:

14 square meters

Step-by-step explanation:

The formula for the area of a parallelogram of length L and height H is

A  = L * H.

Here, the area is A = (2 meters) * (7 meters) = 14 square meters.

This answer hinged upon my understanding of this situation, and could be incorrect because I'm not taking into account the "triangle" mentioned here.  When at all possible you should share any diagrams given in the problem statement, or at least describe them accurately in words.

Answer:

60.4 or 63

Step-by-step explanation:

if the diagonal is 7, do a^2+b^2=c^2   to find vertical height

2^2+b^2=7^2  

4+b^2=49

b^2=45

square root

b= 6.7

solve

6.7*9=60.4

But if 7 is the vertical height, just do b x h

7*9=63

Two gears are in mesh. The first gear is rotating at 60 rpm and has 23 teeth. The second gear is rotating at 5 rpm. How many tee
wolverine [178]

The rotation of the gears in he mesh involves a circular motion

The second gear has 2 teeth

<h3>How to determine the number of teeth?</h3>

The given parameter can be represented using the following ratio:

Ratio = Teeth : Revolution

So, we have:

23 : 60 = Teeth : 5

Express as fraction

23/60 = Teeth/5

Multiply both sides by 5

Teeth = 5*23/60

Evaluate the product

Teeth = 2

Hence, the second gear has 2 teeth

Last June only 0.17 inches of rain fell all month. What is the difference between the average rainfall and the actual rainfall f
spin [16.1K]

Answer:

Part 1) 0.50 inches

Part 2) 1.14 inches

Part 3)

a) 1.25 inches

b) -0.32 inches

Step-by-step explanation:

The complete question in the attached figure

Part 1) Last June only 0.17 inches of rain fell all month. What is the difference between the average rainfall and the actual rainfall for the last June

Let

x ----> the average rainfall for the last June

y ----> the actual rainfall for the last June

The difference  between the average rainfall and the actual rainfall for the last June is given by the expression

(x-y)

we have

x=0.67\ in\\y=0.17\ in

substitute

0.67-0.17=0.50\ in

Part 2) The departure from the average rainfall last July was -0.36 inches. How much rain fell last July?

we know that

The departure from the average is the difference between the actual amount of rain and the average amount of rain for a given month

Let

D -----> the departure from the average

x ----> the average rainfall for the last June

y ----> the actual rainfall for the last June

so

D=y-x

we have

D=-0.36\ in\\x=1.5\ in

substitute the given values

-0.36=y-1.5

solve for y

y=1.5-0.36\\y=1.14\ in

Part 3)

<u>Part a)</u> How much rain would have to fall in August so that the total amount of rain equals the average rainfall for these three months?

<u>Part b</u>) What would the departure from the average be in August in that

situation?

Part a) How much rain would have to fall in August so that the total amount of rain equals the average rainfall for these three months?

Find the average rainfall for these three months

Adds the average rainfall and divide by 3

(0.67+1.5+1.57)/3=1.25\ in

Part b) What would the departure from the average be in August in that

situation?

we know that

The departure from the average is the difference between the actual amount of rain and the average amount of rain for a given month

Let

D -----> the departure from the average

x ----> the average rainfall for the last June

y ----> the actual rainfall for the last June

so

D=y-x

we have

x=1.57\ in\\y=1.25\ in

substitute the given values

D=1.25-1.57=-0.32\ in

What is the perimeter of a rectangle below​
Maru [420]

Answer:

7x + 33 -I could be wrong I'm not an expert in maths jus trying to help

Step-by-step explanation:

x + 13 9x-7

so first you need to times both by two because there are two of both sums

2(x+13) so you times both numbers by 2 so

= 2x+26

and do the same with 9x - 7 so

2(9x-7) = 18x - 14

and then you add them together and find the like terms.

Like terms means for example in the equation:

2x + 3x - 4 + 3

the like terms are the two numbers that are the same like 2x and 3x are the same since they are both the same term and since there is a plus sign before the 3x you add them so 5x and then you need to do -4 + 3 = 7 and so the answer is 5x + 7.

In this case its:

2x + 26 + 5x + 7. So the like terms are 2x and +5x and +26 and +7.

So 2x + 5x = 7x and 26 + 7 = 33.

So the final equation is 7x + 33

Hope this helps :D
