A parallelogram has sides of length 7.7 millimeters and 17.2 millimeters. What is the perimeter?

Answers

Answer 1

Answer: Solutions

We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × (Side A + Side B).

We have the side lengths 7.7 mm and 17.2 mm.

Solve

2 × (Side A + Side B)
2 × ( Side A (7.7) + Side B (17.2) )
= (7.7 x 2) + (17.2 x 2)
= 49.6

The perimeter is 49.6 mm².

Answer 2

Answer: P=2b+2c
P=2(7.7)+2(17.2)
P=15.2+34.4
P=49.6 millimeters

A supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. The supplier sells 1/72 pounds of mulch and gravel combined. How many pounds of each item does the supplier sell?

Answers

Answer:

108 pounds of mulch.

64 pounds of gravel.

Step-by-step explanation:

Let x be the amount of mulch sold and y be the amount of gravel sold.

We have been given that a supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel.

$2(1)/(4)=(9)/(4)$

$1(1)/(3)=(4)/(3)$

We can represent this information as:

$(x)/(y)=((9)/(4))/((4)/(3))...(1)$

We are also told that the supplier sells 172 pounds of mulch and gravel combined. We can represent this information as:

$x+y=172...(2)$

From equation (1) we will get,

$(x)/(y)=(9)/(4)*(3)/(4)$

$(x)/(y)=(27)/(16)$

$x=y*(27)/(16)$

Substituting this value in equation (2) we will get,

$y*(27)/(16)+y=172$

Now let us have a common denominator.

$(27y)/(16)+(16y)/(16)=172$

$(27y+16y)/(16)=172$

$16*(43y)/(16)=16*172$

$43y=2752$

$y=(2752)/(43)$

$y=64$

Therefore, the supplier sold 64 pounds of gravel.

Upon substituting y=64 in equation (2) we will get,

$x+64=172$

$x=172-64$

$x=108$

Therefore, the supplier sold 108 pounds of mulch.

James works in a flower shop he will put 36 tulips in vases for a wedding he must use the same number of tulips in each vase how many tulips could be in each vase

Answers

Okay, so this is just like division. What you have to do is figure out, "If there are 36 flowers, how many vases should their be?" Study the 36 for a minute and think of a number that can be multiplied by the same number that would equal 36. (hint: it's between 2 and 7) Good luck!

To get to your school, 2/5 of the students walk, 1/3 of the students ride the bus, and the rest come in cars. How many students come to school in cars?

Answers

Answer:

You can't tell because you don't know how many students attend the school.

Step-by-step explanation:

6 x 2/5 will be equal to, greather than, or less than 2/5?

Answers

Well, we know that

-- 6 cows are greater than 1 cow

-- 6 trucks are greater than 1 truck

-- 6 candy canes are greater than 1 candy cane

So we're pretty sure that if you have a bunch of boxes with
the same thing in every box, then 6 boxes are going to have
more of it than 1 box has.

Great. That always works. It doesn't matter whether the boxes
all have cookies, hamburgers, puppies, or 2/5 in them. 6 boxes
always have more than 1 box has.

Are you comfortable with this reasoning ?

Answer:

Greater than
