Answer:

it would take him 1.5 hours (an hour and 30min.)

Step-by-step explanation:

120 divided by 8 = 15

15 divided by 10 = 1.5

The number of hours he would need to complete this job is 2.5 hours.

"PEDMAS is an order of operation used in mathematics to deal easily with complex calculations. It states that we start solving any arithmetic expression by solving the terms written in parentheses or brackets and then we simplify exponential terms and move ahead to division and multiplication operations and then, at last, we can find the answer by solving addition and subtraction operations."

According to the question

A construction worker needs to move 120 feet squared (3) of dirt by using a wheelbarrow.

One wheelbarrow load holds 8 feet squared(3) of dirt and each load takes him 10 minutes to complete.

Writing the above statement in mathematical form

= (120 ÷ 8) × 10

By using PEDMAS rule, we get

= 15 × 10

= 150 mins

= 150 ÷ 60

= 2.5 hours

Thus, the number of hours he would need to complete this job is 2.5 hours.

Step-by-step explanation:

First create like dominators

2/3 -1/6  = 4/6 - 1/6

simplify using subtraction

4/6 - 1/6 = 3/6

Simplify the answer

3/6 = 1/2

Answer:

1/2

Step-by-step explanation:

2/3 - 1/6

Subtract the two fractions:

2/3 - 1/6 = 1/2

The answer we get is:

1/2

Divide the numerator by the denominator for the decimal form:

1 ÷ 2 = 0.5

0.5 is our decimal form.

1/2 and 0.5 are our answers.

Answer:

18

Step-by-step explanation:

count

The number of students measured in this sample is 18.

The number of students measured is the number of heights that were acquired for the sample.

Looking at the question, the number of heights acquired were 18 which means that there were 18 students.

Knowing the number of students is important as it can help you calculate things such as mean:

Mean = Sum of heights / Number of students

= (75 + 72 + 72 + 73 + 74 + 65 + 69 + 74 + 70 + 70 + 71 + 75 + 71 + 75 + 69 + 75 + 78 + 70) / 18

= 72.11

In conclusion, the number of students measured is 18.

Answer:

Jack is incorrect. The correct answer is 2

Step-by-step explanation:

The question is given as:

4x-24 / (y+w)  where x=5, y=3 and w= -5

Substitute values of x, y and w in the equation as;

4*5 - 24 / (3+-5)

20 - 24 / (-2)

-4 / -2 = 2

Jack's answer is 7 which is wrong. The correct answer is 2

2 is correct because you have substituted the real values of x,y and w in the expression and performed the operation right.

Answer:

The first order.

Step-by-step explanation:

What do these symbols mean?

The funny shaped line is a square root, meaning what times itself (so for example, 3 x 3) gets that number. So the square root of 9=3.

The small 2 in the top right of the big numbers means square. The opposite. This means multiply that big number by itself twice. If the small number was say, 7, you would multiply the big number by itself 7 times. A common mistake is propel multiply the big number by the small number. The square used in these is 2 to the power of 3, the small number. This means you do 2x2x2, as the small 3 determines how many time you multiply the big number, 2. The result of 2x2x2=8.

The fraction is 11/9. The 9 means how many parts are in a whole number. The 11 means how many of those parts you actually have. Like a pizza-if you had a pizza (the whole) split into 7 parts, 7 would be your bottom number (as the 9 is here). If you are 4 parts and were left with 3 parts, 3 would be your top number (as the 11 is here). Seeing as 11 is bigger than 9, you have to imagine 2 pizzas. Each is split into 9, and you have 11 parts altogether. Thsi is 1 whole pizza and 2 extra parts, making the fraction 1 and 2/9. This is jaut another way to write 11/9 but I find it easier to look at.

The answer?

So. We have established that 11/9 = 1 & 2/9

And that 2 cubed (with the small 3 on it) = 8.

Amd the square roots of 5, 11 and 20 are approximately (Not exactly, but close enough) the following:

5. 2.2

11. 3.3

20. 4.4

So this leaves us a bunch of numbers to put in order from smallest to largest. This is fairly easy. It's not the second one. 8>3.3. It's not the third one. 8>2.2. It's not the fourth one. 1 & 2/9 may be smaller than 8, but 2.2 isn't. So this leaves the first order.

*Note that the symbol > means greater than or bigger than. So 8>2 means 8,is bigger than 2.

Answer:

There are 14 horses and 21 chickens.

Step-by-step explanation:

First, you have to make expression for horse and chicken. So we can let x be the number of horses and y will be the number of chickens. Next, given that the total number of feet for both animals is 98 so you have to make simultaneous equation :

[tex]4x + 2y = 98[/tex]

( horse has 4 feet and chicken has 2 feet )

There are a total of 35 heads so the other equation will be :

[tex]x + y = 35[/tex]

Lastly, you have to solve it :

[tex]4x + 2y = 98[/tex]

[tex]2(2x + y) = 98[/tex]

[tex]2x + y = 49 - - - (1)[/tex]

[tex]x + y = 35 - - - (2)[/tex]

[tex](1) - (2)[/tex]

[tex]2x + y - x - y = 49 - 35[/tex]

[tex]x = 14[/tex]

[tex]substitute \: x = 14 \: into \: (2)[/tex]

[tex]14 + y = 35[/tex]

[tex]y = 35 - 14[/tex]

[tex]y = 21[/tex]

Answer:

10

Step-by-step explanation:

The common ratio of the geometric sequence 10,60, 360,... is 6.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, A geometric sequence 10,60, 360,...

We know the common ratio r in a geometric sequence is

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Therefore,

The common ratio in this geometric sequence  10,60, 360,... is,

= 60/10 = 360/60 = 6.

So, The common ratio is 6.
