Explain why it might be easier to solve the multiplication problem by changing it from this: 5×87×2, to this: 5×2×87. Use a property of multiplication to justify your reasoning.

Answers

Answer 1

Answer:

It makes the calculation easy and quick.

Step-by-step explanation:

Commutative Property of multiplicationThe product of two or more real numbers is not affected by the order in which they are being multiplied. In other words, real numbers can be multiplied in any order because the product remains the same.

When you multiply as it is given:

5×87×2=870Step 1)  5×87 = 435Step 2) 435×2 = 870

Using the commutative property makes it much easier:

5×2×87 = 870Step 1) 5×2 = 10Step 2) 10* 87 = 870
Answer 2

Answer:

see below.

Step-by-step explanation:

its a commutative property of multiplication.

it doesn't matter in order or not... the result will always be the same.

form your example 5×87×2, if you use a calculator it doesn't matter which number you start.

say 2 x 87 x 5 = 870

or 87 x 5 x 2 = 870

or 5 x 2 x 87 = 870

see the results are all the same no matter which way you go.

How do you simplify it? I know the answer is 6_/6p but I don’t really know *how* to get there.

Answers

Answer:

The answer is

[tex]6 \sqrt{6p} [/tex]

Step-by-step explanation:

[tex] \sqrt{216p} [/tex]

First of all factor out the perfect square

From the question the perfect square is 36

We have

[tex] \sqrt{36 \times 6p} [/tex]

The root of a product is equal to the product of the roots of each factor

That's

[tex] \sqrt{36 \times 6p} = \sqrt{36} \times \sqrt{6p} [/tex]

Simplify

[tex] \sqrt{36} = 6[/tex]

So we have

[tex]6 \times \sqrt{6p} [/tex]

We have the final answer as

a temperature recorded in Antarctica was -122 F. The temperature recorded in the desert was 133 F. how many degrees warmer is 133 F than 122 F

Answers

Answer:

255 F

Step-by-step explanation:

133 + 122 = 225.

So that is the answer.

133°F is 255 degrees warmer than -122°F.

To find out how many degrees warmer 133°F is than -122°F, we can subtract the two temperatures:

Temperature difference = 133°F - (-122°F)

Remember that subtracting a negative number is the same as adding its positive value, so the calculation becomes:

Temperature difference = 133°F + 122°F

Temperature difference = 255°F

So, 133°F is 255 degrees warmer than -122°F.

On the other fountain that sells for $1.260, she gets $252.During a 3-month selling season, Ingrid sold 19 of the lower-priced fountains and 23 of the higher-priced fountains. What were her total commissions for three months?

Answers

Answer:

$9,102

Step-by-step explanation:

Ingrid Sering sells two types of garden fountains on a straight commission basis. On one fountain that sells for $869, she gets a commission of $174. On the other fountain that sells for $1,260, she gets $252.During a 3-month selling season, Ingrid sold 19 of the lower-priced fountains and 23 of the higher-priced fountains. What were her total commissions for three months

From the question above, we have the following information:

On one fountain that sells for $869 = she gets a commission of $174( the lower-priced fountains)

On the other fountain that sells for $1,260 = she gets $252 ( the higher-priced fountains)

Ingrid sold 19 of the lower-priced fountains)

1 fountain sold = $174 of commission

19 fountains sold =

$174 × 19

= $3,306

She also sold 23 of the higher-priced fountains)

1 higher priced fountains = $252

23 higher priced fountains =

$252 × 23

= $5,796

Hence, the Total commission Ingrid made = Total commission on Lower priced fountains + Total commission on Higher priced fountains

= $3,306 + $5,796

= $9,102

Therefore, the total commission Ingrid made = $9,102

triangle A’ B’C’ is a dilation of ABC... What is AB?

Answers

Answer:

Option C.

Step-by-step explanation:

From the picture attached,

ΔA'B'C' is a dilation of ΔABC which means image ΔA'B'C' is similar to ΔABC.

By the property of similarity corresponding sides of both the triangles will be proportional.

[tex]\frac{\text{AB}}{\text{A'B'}}=\frac{\text{BC}}{\text{B'C'}}=\frac{\text{AC}}{\text{A'C'}}[/tex]

[tex]\frac{AB}{6}=\frac{15}{10}[/tex]

AB = [tex]\frac{6\times 15}{10}[/tex]

AB = [tex]\frac{90}{10}[/tex]

AB = 9 units

Therefore, length of side AB = 9 units.

Option C. will be the answer.

Sushmit Answer

Answers

Answer:

The mapping diagram above is a function since there are no two values (integers) in the range (Set B) where there is only one value (integer) in the domain (Set A) mapped unto them

Step-by-step explanation:

By definition a function is an association between the individual elements within two sets such that all element in one set is mapped to precisely one element of the other set

In the given example, all the elements in Set A are mapped to exactly one element of the Set B

That is the function from A to B is the set C (-1, -4), (9, 5), (1, 4), whereby the first component of the ordered pair in the set C are the elements of the set A.

The mapping diagram above is a function since there are no two values in set B where there is only one value in Set A mapped to them.

A function has a very unique attribute of having one output attributed to each input.

The Set A is the domain while set B denotes the range. Hence, each value in the domain would have exactly one value in the range which would be different for each value in the domain.

Therefore, since the mapping diagram illustrates a 1 input to 1 output relationship, then it is a function.

An object is moving at a speed of 3 kilometers every 5 days. Express this speed in yards per hour. Round your answer to the nearest tenth

Answers

Answer: 27.3 yards per hour

Step-by-step explanation:

First convert 3 kilometers to yards    

3 km to yards is  3280.84  

now we have to convert 5 days to hours. If there are 24 hours per day  then we will multiply 24 by 5 to determine hours are in 5 days

5 * 24 = 120  hours  

Now divide divide 3280.84  by 120  to find the speed in yards per hour

3280.84 / 120 = 27.34  yards per hour  

27.34  rounded to the nearest tenth is 27.3

The object is moving at a speed of 2734.025 yards per hour.

What is a unitary method?

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

We know 1 kilometer is 109361 yards and one day is equal to 24 hours.

Given, An object is moving at a speed of 3 kilometers every 5 days.

∴ The object is moving at a speed of (3×109361) = 328083 yards in

(5×24) = 120 hours.

Hence in 1 hour, the object moves (328083/120) yards = 2734.025 yards.

Find the width and height of a 54 inch TV with the aspect ratio of 4:3. Then , find the area of the screen. You must draw and label a picture to help show ur work.

Answers

Answer:

The area of the screen is 1399.68 in²

Step-by-step explanation:

The given parameters are;

The size of the TV = 54 inch

The aspect ratio of the TV screen = 4:3

The size of the TV is given as the length, of the diagonal, therefore, we have;

The aspect ratio = Length, L:Width, W = 4/3 = L/W

L² + W² = 54²..................(1)

L/W = 4/3.........................(2)

Therefore, 3×L = 4×W

L = 4×W/3

Substituting the value of L in equation (1), we have;

(4×W/3)² + W² = 54²

16/9×W² + W² = 54²

25/9×W² = 54²

W² = 54²×9/25 = 1049.76

W = 32.4 inches

The length, L = 4×W/3 = 4×32.4/3 = 216/5 inches = 43.2 inches

The area of the screen = 43.2 inches × 32.4 inches = 1399.68 in²

The area of the screen =  1399.68 in².
