if the area of a parallelogram is 86cm and the height is 12cm write an equation that relates the height,base and area of the parallelogram

Answers

Answer 1

Answer:

Answer:

The relation to find base is, $base=(area\ of\ the \ parallelogram)/(height)=(86)/(12)=7.16\ cm$

Step-by-step explanation:

Given

Area of the parallelogram $=86\ cm^2$

Height of the parallelogram $=12\ cm$

We know that the area of the parallelogram $=base* height$

To find base we have to divide the height on both sides of the equation.

$base=(area\ of\ the \ parallelogram)/(height)$

Plugging the values.

$base=(86)/(12) =7.1\ cm$

So the base in terms of area of the parallelogram and its height is $b=(area)/(height) =(86)/(12)=7.16\ cm$

Frank lives 6 miles away from school. If he rode his bike 7/8 miles and walked the rest, how many miles did he ride his bike?

Answers

we need to find 7/8 of 6. to do this we multiply them together. we write 6 as 6/1 and multiply across to get 42/8 or 5 2/8 simplified to 5 1/4 as a mixed fraction. Frank rode his bike 5 1/2 miles to school

Bob and Cheryl are taking a road trip that is 188.3 miles. Bob drove 5/7 of the totalDistance. How many miles did Bob drive?

Answers

the total distance of the road trip is 188.3 miles

Both Bob and Cheryl took turns and drove

Bob has driven 5/7th of the total distance

distance Bob has driven - $(5)/(7)of188.3miles$

when the 'of' function is used we have to multiply

$(5)/(7)*188.3 = (5*188.3)/(7) = 134.5$

therefore distance Bob drove is 134.5 miles

$x-\ distance\ drove\ by\ Bob\n\ny-\ distance\ drove\ by\ Cheryl\n\nx=(5)/(7)*188,3\ny=188,3-x=188,3-(5)/(7)*188,3=(2)/(7)*188,3\n\ny=53,8\ miles\n\nx=134,5\ miles\n\nBob\ drove\ 134,5\ miles.$

Answer:

The parallelograms PQRS and TUVW are not alike.

Step-by-step explanation:

In a parallelogram, if one angle is known, then all the other angles can also be determined.

Now, parallelograms PQRS and TUVW have one angle of 120° equal.

So, the other three angles will be the same for them.

The adjacent sides of the parallelogram PQRS are 8 ft and 12 ft. and the adjacent sides of the parallelogram TUVW are 2.4 ft and 5.2 ft.

So the ratios of sides of the two parallelograms are $(8)/(2.4) = 3.33$ and $(12)/(5.2) = 2.3$ which are not equal.

So, the parallelograms PQRS and TUVW are not alike. (Answer)

Carl and Rita ate breakfast at the local diner. Their bill came to $11.48. They gave their waitress a tip that was 25% of the bill. How much money did they give the waitress for her tip?

Answers

Converting percentage to a decimal:
25% = 25 / 100 = 0.25

What is 25% of 11.48
= 25% * 11.48
= 0.25 * 11.48
= 2.87

Identify the slope and y-intercept of the line 8x+2y=6

Answers

The required slope and y-intercept of the line are -4 and 3 respectively.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

here,
Given the equation of the line,
8x + 2y = 6

Arrange the above equation as the subject of y,
2y = -8x + 6
y = -4x + 3

Comparing the above equation of the line with the standard equation of the line, y = mx + c
m = -4 and c = 3

Thus, the required slope and y-intercept of the line are -4 and 3 respectively.
