Answer 1

Answer:

7^2 =49

Step-by-step explanation:

Exponents represent a number and how many times you multiply it by itself. So 5^2 is 5*5 or 4^3 is 4*4*4. So 7^2 is 7*7, which is 49!

A bag contains 5 yellow balls 3 red balls and 2 green balls. A ball is removed from the bag without looking, the colour recorded, and then returned the bag. A second ball is drawn and its colour is also recorded.

c) What would be the outcome of the 2 balls if it has a probability of 1/10?

Answers

Answer:

the two balls are yellow and green, in either order.

Step-by-step explanation:

P(Y) = 5/10 = 1/2

P(R) = 3/10

P(G) = 2/10

Since the only combination that makes a product of 1/10, so

P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10

So the two balls are yellow and green, in either order.

The balls of two are yellow and green,in either order.

Answers

Answer:

As a decimal your answer: is 5.4 rounded to the nearest tenth. As a mixed number fraction your answer is: 5 11/25. As a improper fraction your answer is: 136/25.

Step-by-step explanation:

Basically what I did was just divide 6.8 by 4/5. Or you could change 4/5 in a decimal and divide like that, OR change 6.8 into a fraction which is what if did- I’ll show you below. But, it’s better to have all solutions to the problem.

1) change 6.8 into fraction: 34/5

2) rewrite: 34/5 divide by 4/5

3) multiply: 136/25

4) alternative forms:

A. Mixed number- 5 11/25

B. Decimal: 5.44 or 5.4 rounded to nearest tenth.

Ed is building a model of a house with a flat roof, as shown in the diagram. There is a chimney through the roof. Ed will cover the roof with square tiles.

If the area of each tile is 1 square inch, how many tiles will he need?

Answers

Answer:

Step-by-step explanation:

3x4

You will need to find the area first so 50in x 40in =2,000in

Then find the area the chimney takes up. 4in x 3in = 12in

2,000in - 12in =1,988 tiles for the roof.

A carpenter's tool box is made up of nails, screws, washers, and brackets in a ratio of 4:11:9:6. The total number of the pieces in the box is 60. If 5 carpenters have identical tool boxes, how many total washers are in the boxes?
A. 18
B. 48
C. 62
D. 90

Answers

Answer: D 90

Step-by-step explanation:

One way to do this follows:  Find the ratio, r, which when multiplied by each of the four numbers in the ratio produces the actual number of parts present:

4r + 11r + 9r + 6r = 60

Summing these up results in 30r = 60, so r is 2.

There are 4(2), or 8, nails,

11(2), or 22, screws,

9(2), or 18, washers, and

6(2), or 12, brackets.

Note that 8 + 22 + 18 + 12 = 60 (total number of parts)

If 5 carpenters have identical boxes, there will be 5(18), or 90, total washers.

The sum of two numbers is 80. If the difference between the same two numbers is 8, find the two numbers.

Answers

Answer:

The numbers are 44 and 36

Step-by-step explanation:

n + n - 8 = 80

2n - 8 = 80

2n (- 8 + 8) = 80 + 8

2n = 88

2n/2 = 88/2

n = 44

44 - 8 = 36

Numbers are 44 and 36 they have a difference of 8 and combine to make 80

Which graph represents the solution of 3y-9≤6x?

Answers

A is correct when you do this B looks close but it’s A

The graph that represents the solution of 3y - 9 ≤ 6x is option A.

Option A is the correct answer.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

3y - 9 = 6x

We can find the following coordinates.

When x = 0,

3y - 9 = 0

3y  9

y = 3

When y = 0,

3y - 9 = 6x

-9 = 6x

x = -9/6

x = -3/2

x = -1.5

Thus,

The graph on option A represents the solution.
