Step-by-step explanation:

A ceramic artist can shape a pot in 3 minutes. It takes 10 minutes to fire one batch of pots in the kiln. If there are p pots in a batch, which expression represents the time it takes to shape and fire one batch of pots? How long will it take the potter to form and fire a batch of 10 pots? A.The expression is 3p. It takes 30 minutes to shape and fire 10 pots.B.The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots.

C.The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.

D.The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.

Answers

Answer:

D. The expression is $3p+10$ . It takes 40 minutes to shape and fire 10 pots.

Step-by-step explanation:

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take $3p$ minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

Thus, the expression for the time taken to form one batch of pots = $3p+10$

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = $3* 10+10$ = 30+10 = 40

That is, 'It takes 40 minutes to shape and fire 10 pots'.

Thus, option D is correct.

3p to shape and 10 minutes to fire
= 3p + 10
3x10 + 10 = 40 minutes for a batch of 10 pots
therefore D is the correct answer

Find the perimeter and area. (plz help with the answer)

Answers

Hello!

PERIMETER:

To find the perimeter of the trapezoid, simply add all sides together.

15 + 5 + 9 + 5 = 34

The perimeter is $\boxed{ \bf 34~units.}$

____________________________________________________________

AREA:

A = $(1)/(2)$ h( $b_(1)$ + $b_(2)$ )

A = $(1)/(2)$ 4(9 + 15)

A = $(1)/(2)$ 4(24)

A = 2(24)

A = 48

The area of the trapezoid is $\boxed{ \bf 48~units^2}$

I NEED HELP PLZZZ Josh simplified 4x - 8x / 2 and said the answer was -2x. What was Josh's error? What should his answer have been?\

Answers

Hello there,

This is a trick question Josh did not have an error. If you have 4x-8x in the numerator that becomes a -4x/2.
So then -4x/2= -2x
Josh was not wrong.

I hope this helped!

25)There are 200 students in 6th period lunch. The ratio of 7th graders to 8th graders is 4 to 5. What percent of the students are 7th graders?A) 44
B) 55 9%
C) 89%
D) 80%

Answers

There are 200 students in 6th period lunch.
The ratio of 7th graders to 8th graders is 4 to 5.
Let's find the percentage of the students are 7th graders:
=> 200 / 9 = 22.22
=> 22.22 * 5 = 111.11 or 111
=> 22 * 4 = 88.88 or 89
=> 4 : 5 or 89 : 111
7th grader = 55%

A regular heptagon has sides measuring 26 mm and is divided into 7 congruent triangles. Each triangle has a height of 27 mm. What is the area of the heptagon?

Answers

The solution is : 2,457 mm^2, is the area of the heptagon.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

The dimensions of each of the triangles in terms of their bases and heights will be;

26 mm by 27 mm

Mathematically, the area of one of the triangles will be ;

1/2 * base * height

= 1/2 * 26 * 27

= 351 mm^2

So the area of the heptagon is the sum of the areas of all of the triangles

mathematically, that would be;

351 * 7

= 2,457 mm^2

Hence, The solution is : 2,457 mm^2, is the area of the heptagon.
