Communitive Property:

            Addition and Multiplication.

Associative Property:

            Addition and Multiplication.

Identity Property:

            Additional and Multiplication.

Distributive Property

Step-by-step explanation:

Communitive Property:

Addition; When two numbers are added, the sum is the same regardless of the order in which the  numbers are added. (3 + 2 = 5 or 2 + 3 = 5)

Multiplication; When two numbers are multiplied together, the product is the same regardless of the order in which the numbers are multiplied.

(4 x 3 = 12 or 3 x 4 = 12)

Associative Property:

Addition; When three or more numbers are added, the sum is the same regardless of the way in  which the numbers are grouped.

6 + (4 + 3) = 13 or (6 + 4) + 3 = 13

Multiplication; When three or more numbers are multiplied, the product is the same regardless of

the way in which the numbers are grouped.

6 x (4 x 3) = 72 or (6 x 4) x 3 = 72

Identity Property:

Addition; The sum of any number and zero is that number.

(10 + 0 = 10)

Multiplication; The product of any number and one is that number.

(33 x 1 = 33)

Distributive Property:

The sum of two numbers times a third number is equal  to the sum of each addend times the third number. 6(3 + 4)

(Multiply 6 by both numbers, 6 x 3 = 18 and 6 x 4 = 24, and then add the sums; 18 + 24 = 48.

Answer:

After the discount, Glenda will pay 210. If you multiply the total sum by the percentage converted into a decimal, you'll typically get your answer.

2. 9.75

3. -24%

Step-by-step explanation:

For number 2, multiply the total sum by the percentage converted into a decimal point then whatever result you get, I.E 2.25 in this case, and add it to the total sum (7.50), so 7.50 + 2.25 = 9.75 or 10 rounded up.

Answers

Answer:

whats the question here?

Step-by-step explanation:

Answer:

Hi there!

In order to answer your question, you'll need to use the cross product method:

1 cup water → 1/4 cup sugar

10 cups water → X cup sugar

((1/4) × 10) ÷ 1 = X cups sugar

2.5 ÷ 1 = X cups sugar

2.5 = X cups sugar

Your answer is : Using 10 cups of water, you should add 2 and a half cups of sugar so that the large batch tastes the same as the test batch.

On a recent math test, Pedro was asked to solve: 526 ÷ 19. His answer was 26 R 32. His answer was marked incorrect. What mistake did Pedro make? What should his answer be?

Answers

Answer:

I think the anwser is 27R 13

Step-by-step explanation: The mistake was he probably subtrcted or borrowed wrong

The mistake Pedro made was he said 19 goes into 146 6 times instead of 7.

Explanation: 526/19
19 goes into 52 twice, 52-38 is 14, bring down the 6, 146. 19 goes into 146 7 times, 146-133 is 13, giving you an answer of 27 R 13

For what values of r will the area of the shaded region be greater than or equal to 12 square units? Write your answer as an inequality.

STEP 2: The values are .

Answers

Answer:

Draw a rectangle.. write 13 on the two longer sides of the rectangle then write 7 on the other two shorter ones. Then add them all up and there you go your answer!

Our equation would be 13 +  13 + 7 + 7 = 40 inches

Step-by-step explanation:

The values of r for which the shaded region will be greater than or equal to 12 square units is;

r ≥ 8

We can see a rectangle and a triangle in the given image.

With the triangle being the unshaded portion of the rectangle.

Thus;

Area of shaded portion = Area of rectangle - area of rectangle.

We know that formula for area of rectangle is;

A_r = length × width

Thus; A_r = 3 × r

A_r = 3r

Area of a triangle is;

A_t = ½ × base × height

A_t = ½ × r × 3

A_t = ½(3r)

Thus;

Area of shaded portion = 3r - ½(3r)

Area of unshaded portion = 1.5r

We are told that the area of the unshaded region should be greater than or equal to 12. Thus;

1.5r ≥ 12

r ≥ 12/1.5

r ≥ 8

A Ferris wheel has an area of 50 square meters. Find
the radius of the Ferris wheel to the nearest meters.
Round the answer to the nearest whole meter.

Answers

Answer:

19.7 m

Step-by-step explanation:

Draw a circle to represent the ferris wheel with a 10.2 m radius. Draw a horizontal line through the circle center horizontal to the ground (at 13.1 m). Now draw a line from the center of the circle (ferris wheel) upward at 140 degrees until you reach the edge of the circle. Draw a line down from that point to the horizontal line at This is your right triangle to solve.

Hypotenuse is 10.2 m (radius of circle)

The angle of the triangle the supplementary angle of 140 degrees. 180-140=40 degrees

sin 40 degrees=rise /radius=rise/10.2

sin 40=0.6428=rise/10.2

rise=10.2(0.6428)

rise=6.6 m

13.1+6.6=19.7 m

The radius of the Ferris wheel to the nearest meters will be 4 meters.

What is the area of the circle?

It is the close curve of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

A Ferris wheel has an area of 50 square meters. Then the radius is calculated as,

πr² = 50

r² = 15.915

r = 3.989

r ≈ 4 meters

The radius of the Ferris wheel to the nearest meters will be 4 meters.

Pi(r)^2 is area of a circle. Pi(r)^2=225(pi), solve for r. R=15. 15x6=90. New radius=90. Using area of circle formula, Pi(90)^2=8100 (pi)
