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.

Step-by-step explanation:

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.

Write the word sentence as an inequality. Then solve the inequality.

Six times a number x is at least −24.

The inequality is_ .

STEP 2 :

The solution of this inequality is_ .

Answers

Answer:

6x [tex]\geq[/tex] -24

x = -4

Step-by-step explanation:

There's not really much work that goes into this problem.

First, you have to get the variable by itself. To do that you do the opposite of multiplication which is division. 6 divided by 6 = 0. Since you did that to one side you have to do it to the other. -24 divide by 6 = -4. So, x = -4.

I hope this helped!

6x ≥ -24

x = -4 but I think

x ≥ -4

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.

Jim is a 21-year-old male in his third year of college, and he has decided that it is time for him to get back in shape. During high school, Jim was active in sports and followed a healthy diet, but the demands of work and study, and his social life have taken their toll on Jims health. He weighs more, doesnt exercise, drinks on the weekends, eats a lot of fast foods like hamburgers and French fries, donuts, and pizzas, and he began smoking about three years ago. Due to the pressures of study and work, Jim also gets very little sleep.Since Jim has decided to get back in shape, his first step was to get a checkup in the schools health clinic. During the physical exam, the nurse measured Jims height, weight, and blood pressure. Jim is 1.8 meters tall, weighs 90 kilos, and his blood pressure is 132/84 mmHg. Jim was not concerned until his doctor informed him that high blood pressure or hypertension is a blood pressure of 140/90 mmHg or higher. Jims blood pressure value qualified him as prehypertensive, which means that he has an increased risk of developing hypertension in the future. Jim told his doctor that several family members on his dads side of the family have hypertension, and some had died before the age of 50 of heart attacks.Hypertension is a disease of the cardiovascular system that is correlated with an increase in heart disease, stroke, and kidney disease and vision problems. Most people consider hypertension to be a disease of middle age, but almost one in five young adults are affected as well, making it one of the major health risks facing young adults.After speaking with his doctor, Jim realized that he knew very little about how his body worked, and had never considered how his life style choices influenced his health. He was determined to learn more about how his body functions, especially the cardiovascular system. He also wants to work on making positive changes in his lifestyle, starting with changes in his diet. He needs your help with his new objectives.1.
