Drag each expression to show whether it is equivalent to 4 × 5 or to 2 × 4 × 5.

Answers

Answer:

1st one: 4x5x2: in the 2nd box

2nd one: (4x2)+(4x3) : in the 1st box

3rd one: 2x(4x5): in the 2nd box

Last one: 4x(1+4): in the 1st box

Step-by-step explanation:

For the first one: 4x5x2, you can multiply any 2 numbers together example- you can multiply 4x5, 5x2, 4x2 then multiply the third digit I did 4x5=(20) x2= 40.. 5x2 =10 x4=40.. see they'll all end up to 40.

For the second one: (4x2)=8 (4x3)=12 add 8 and 12 it'll equal 20

For the third one: 2x(4x5) start by multiplying 4 and 5 which is 20, then multiply 20 by 2 =40

For the fourth one: 4x(1+4) 1+4=5, multiply 5 by 4 and get 20

The first box equals 40, the second box equals 20

And always remember to answer the problem in the parenthesis first, then continue with the rest of the problem. Hope this helps!! And I hope I didn't confuse any of you.. Let me know if you have any questions or if I made a mistake somewhere but besides all that have a great day! :)

4 × 5 equivalent to (4×2) + (4×3) and  4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and  2(4×5)

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

= 4×5×2 = 40

=(4×2) + (4×3) = 8+12 = 20

= 2(4×5) = 40

= 4(1+4) = 4(5) = 20

We have:

4 × 5 = 20                                       2 × 4 × 5 = 40

(4×2) + (4×3)                                               4×5×2

4(1+4)                                                          2(4×5)

Thus, 4 × 5 equivalent to (4×2) + (4×3) and  4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and  2(4×5)

A pair of retro Air Jordans is priced at $250 is on sale for 20% off. How much is the discount?

What is the sale price of the sneakers?

Answers

50 because you make 20% into a decimal and multiply 250 and .20

Answer:

The discount is $50

The sale price is $200

Step-by-step explanation:

x/250 = 20/100

Cross multiply

x × 100 = 250 × 20

100x = 5000

Divide both sides by 100 to isolate variable x

100x ÷ 100 = 5000 ÷ 100

x = 50

$50 is the discount price

Take the original value of the shoes and subtract the discount to find the sale price

250 - 50 = 200

$200 is the sale price

Carrie and Diana ate lunch at a restaurant.

They ordered 1 pizza that cost $13.02.
Diana ordered chicken wings for $12.99 and a drink for $3.25.
Carrie ordered a salad for $6.25 and a drink for $3.25.
They left a $10.00 tip.
Diana paid for her food, plus half the cost of the pizza and half the tip. What was the total amount Diana paid?

A.$33.78

B.$27.75

C.$27.04

D.$20.77

Answers

Answer:

B) 27.75

Step-by-step explanation:

12.99+3.25=16.24

Half the tip is 5

5+16.24=21.24

Half the pizza is 6.51

21.24+6.51=27.75

The total amount paid by Diana will be equal to $27.75. Hence, option B is correct.

What is arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data given in the question,

Price of pizza = $13.02

Half price of pizza paid by Diana = 13.02/2 = $6.51

Price of chicken wings ordered by Diana = $12.99 and,

Price of drink that is also ordered by Diana = $3.25

Then, tip price is $10 which is paid half by Diana = $5

Then, the total expenditure by Diana will be,

= 6.51 + 12.99 + 3.25 + 5

= $27.75

Cynthia wants to decorate a round photo frame for her brother. If the diameter is 18 cm what is the circumference of the frame?
A. 56.52 cm
B. 54 cm
C. 28.26 cm
D. 113.04 cm

Answers

Answer:

A. 56.52

Step-by-step explanation:

Circumference = 2πr

Radius is half of the diameter, but 2 times radius is also simply the diameter. Therefore, the solution of the problem would be 18 times π. In this case, we can round π to 3.14, and 18 times 3.14 is 56.52.

56.52 should be the answer . A is the correct answer

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, A golfer hits a golf ball, where x is the time in seconds and y is the height of the ball.

Now when a golfer will hit the ball as time progresses it will gain a height after some time just before falling down the ball will attain its maximum height and then it falls gradually influenced by gravity.

which expressions represents a 20% discount off the price of an item that originally cost D dollars ​

Answers

Answer:

D - (D/5)

Step-by-step explanation:

Let's imagine that D equals 100 dollars -

Well, we know that to get 20% of an amount, we need to divide the amount by five. So let's do that -

100 / 5 = 20

We now know that 20% of 100 dollars is equal to 20 dollars. We have now finished the first part. On to the second part.

We now need to take away 20% of 100 dollars off of 100 dollars - this is the price of the item after the discount.

100 - 20 = 80 dollars.

We now fit in D instead of 100 dollars -

D - (D/5)
