Use rounding to estimate the product of 198 and 42 . Round both numbers to the nearest ten to find your answer.

Answers

Answer 1

Answer:

8000

Step-by-step explanation:

198 and 42 rounded to the nearest hundreths are 200 and 40. the product of 200 and 40 is 8000

Answer 2

The product of 198 and 42 rounded both numbers to the nearest ten

is 8000.

What is rounding off of numbers?

We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, Use rounding to estimate the product of 198 and 42.

Now, 198 rounded to the nearest ten is 200, and 42 rounded to the nearest ten is 40.

Therefore, The multiplication of 198 and 42 rounded to the nearest 10 is,

= 200×40.

= 8000.

The volume of a cylinder is 675π cm3. The radius of the base of the cylinder is 5 cm. What is the height of the​ cylinder?

Answers

Answer: 27 cm

Step-by-step explanation:

We know that the volume of a cylinder is [tex]V=\pi r^2h[/tex]. Since we were given the volume and radius, we can plug them in and solve for height.

[tex]675\pi =\pi (5^2)h[/tex]              [divide both sides by π]

[tex]675 = (5^2)h[/tex]                  [exponent]

[tex]675=25h[/tex]                     [divide both sides by 25]

[tex]h=27[/tex]

Now, we know that the height is 27 cm.

A salesman need to sale 63 items to make it monthly go there are 18 selling days left in the month what is the average number of items you need to sell daily to reach his goal?

Answers

Answer:

He needs to sell an average of 3.5 items a day to reach his goal.

Step-by-step explanation:

To find the average he needs to sell, we need to divide the items he needs to sell by the number of days he has left to sell. He has 63 items and needs to sell them within 18 days.

63/18=3.5

He needs to sell an average of 3.5 items a day to reach his goal.

The salesman should sell 3.5 items on a daily average to reach his target when he needs to sell 63 items in 18 selling days.

What is average?

The average is defined as the sum total of observations divided by the total number of observations.

How to solve the question?

In the question, we are informed that a salesman needs to sell 63 items to make it monthly within 18 selling days left in the month.

We are asked the average number of items he should sell daily to reach his goal.

The average number of items per day can be calculated as the ratio of the total number of items left to the total number of days left.

Therefore, the average number of items per day = 63/18 = 3.5.

Rosa is putting carpet in her room. She’s using the scale 1 inch = 3 ft . In the drawing, the length is 5.5 inches and the width is 3.25 inches. If carpet costs 2.58 per square foot, how much will it cost to carpet the bedroom?

Answers

Given :

Rosa is putting carpet in her room. She’s using the scale 1 inch = 3 ft .

In the drawing, the length is 5.5 inches and the width is 3.25 inches. If carpet costs 2.58 per square foot.

To Find :

How much will it cost to carpet the bedroom.

Solution :

Length of bedroom , l = 5.5 × 3 = 16.5 ft.

Width of bedroom , w = 3.25 × 3 = 9.75 ft.

SO, area of bed room is :

[tex]A=l\times w\\\\A=16.5\times 9.75\ ft^2\\\\A=160.875\ ft^2[/tex]

Now, cost to carpet the bedroom is :

[tex]C=2.58\times A\\\\C=2.58\times 160.875\\\\C=415.0575[/tex]

Hence, this is the required solution.

Martha has 90 red tiles and 72 yellow tiles. She wants to place the tiles in rows using one color for each row without having any tiles left
over. Each row must have the same number of tiles. What is the greatest number of tiles Martha can use for each row?

Answers

Answer:

18 tiles

Step-by-step explanation:

If she wants to find the greatest number of tiles for each row, she will want to use up all the tiles. This means we are looking for the highest common factor between the numbers 90 and 72, so all the tiles can be used up in the rows. In order to find the highest common factor we multiply together all the common prime factors between the two:

90 has the prime factors 2x3x3x5

72 has the prime factors 2x2x2x3x3

The prime factors that are common to both are 2, 3 and 3 which multiply together to get:

2x3x3 = 18

The greatest number of tiles Martha can use for each row is 18 and would result in 5 rows of red tiles and 4 rows of yellow tiles.

Solution:

Substitute the values of x & y into the first equation
6 -(-1) = 3
6 + 5 is NOT equal to 3
Therefore we can say this is not true
For this to be true, when substituting the values of x & y, the equation must be true for BOTH equations. Since it’s not true for the first equation it doesn’t matter if it’s true or not for the other equation.

Find the coordinates of point P that partition AB in the
ratio 1:4.

Please give explanation

Answers

Answer:

(1.6, 0)

Step-by-step explanation:

Point P, partitioning AB in the ratio 1:4, implies that it divides AB into, AP and PB, such that AP to PB = 1:4.

Use the formuka below to find the coordinates of point P:

[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]

[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]

Where,

[tex] A(1, -1) = (x_1, y_1) [/tex]

[tex] B(4, 4) = (x_2, y_2) [/tex]

[tex] m = 1, n = 4 [/tex]

Solve by plugging the above values where necessary as follows:

[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]

[tex] x = \frac{1(4) + 4(1)}{1 + 4} [/tex]

[tex] x = \frac{4 + 4}{5} [/tex]

[tex] x = \frac{8}{5} [/tex]

[tex] x = 1.6 [/tex]

[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]

[tex] y = \frac{1(4) + 4(-1)}{1 + 4} [/tex]

[tex] y = \frac{4 - 4}{5} [/tex]

[tex] y = \frac{0}{5} [/tex]

[tex] y = 0 [/tex]

The coordinates of P that partitions AB into the ratio 1:4 are (1.6, 0)
