How do you use equations to solve problems about area of Rectangles,Paralellograms , trapezoids and triangles

Answers

Each shape has a different formula for area. rectangles and parallelograms share the same formula, A=bh
Trapezoids formula is A= 1/2(b1 + b2)h
Triangles formula is A = 1/2bh
In all of these formulas, A means area, and h means the height of the shape. In the formulas for triangles and rectangles/parallelograms, b stands for the length of the base of the shape.
In the trapezoids formula, b1 means base 1 and b2 means base two, as a trapezoid has two different bases.
After finding all of the variables for the formula of the shape you're solving for, plug all the numbers into your missing variables, and solve as normal.

Determine the x-intercept, y-intercept, and slope of the line described by -3x+7y=-21

Answers

Answer:

Step-by-step explanation:

Comparing to Y = MX + c

M is the slope and c is intercept

-3x+7y=-21

7y = 3x - 21

y = 3/7x - 21/7

y = 3/7x - 3

Slope= 3/7

Intercept= -3

How long was a million days ago in hours?

Answers

There are 24 million hours in one million days

The number of hours in a day is :

1 day = 24 hours

Number of hours in a million days would be :

1 million days * 24 hours

1000000 * 24 = 24000000

Hence, there are 24 million hours in one million days

Big Al, the ape, ate 100 bananas from May 1 through May 5. Each day he ate six more bananas than on the previous day. How many bananas did Big Al eat on May 5?

Answers

Set up an expression.
Each day he ate 6 more bananas, so

x will be the number of bananas he ate on the first day.
x + (x+6) + (x+6+6) + (x+6+6+6) + (x+6+6+6+6) = 100
5x +60 = 100
5x = 40
x = 8

Now on the 5th day, May 5, he ate (x+6+6+6+6), which is (8+6+6+6+6+6), which equals 38.
On May 5, he ate 38 bananas.

the mean of Gregs journey times to work on 3days was 28minutes If it took him 27min and 25min on two of the days how long did it take him on the third day

Answers

In order to work out the mean, we add all the values together and then divide by how many values we had. In this case we had
(27 + 25 + x)/3 = 28

To work out what the third day (x) was, we must work backwards and do the opposite.
If finding the mean was adding then dividing, to find the value, we must multiply and then subtract.
Instead of diving by 3, we multiply by 3
28 x 3 = 84
Next we subtract the two values we already have, from 84
84 - 27 = 57
57 - 25 = 32 minutes

On the third day, Greg took 32 minutes to get to work.

mean means average basically you do (total amount over time)/(total time)
in this case
(25+27+x)/(3)=28
solve for x
multiply both sides by 3 to clear fraction
25+27+x=84
add like terms
25+27=55
52+x=84
subtract 52 from both sides
x=32

he worked 32 mins
