Answers

Answer 1

i hope this helps you

length 2w+3

width w

Perimeter=2 (width+length)

30=2 (w+2w+3)

15=3w+3

3w=12

w=4

2w+3=2.4+3=11

Answers

Use a calculator or long division to convert the fractions to decimal form

So Jon has the best ratio since it's the largest. Jon is the best shooter of this group

Answer:

Jon was a better shooter

Step-by-step explanation:

To compare the three players foul shot ratio, convert all of them in decimals as follows:

Jon: 18/19 = 0.947

Jim: 5/8 = 0.625

Joe ratio was: 0.94

The best shooter is Jon because his ratio is the greatest one.

The salaries of three employees are listed below. Each employee was recently given a raise.

Employee Salaries
Employee Salary
[before raise] Raise
Jane $41,100 4%
John $43,300 4.5%
Jack $39,900 3%

Which amount is closest to the total of all three raises?

$14,295
$4,723
$10,566
$4,790

Answers

Which amount is closest to the total of all three raises?
A.) $14,295
B.) $4,723
C.) $10,566
D.) $4,790
The amount that's closest to the total of all three raises is D.) $4,790

To calculate the total of three employees' raises, each employee's current salary is multiplied by their respective raise percentage and then added together, resulting in the closest total of $4,790.

The question involves calculating the total amount of the raises given to three employees. We need to apply the given percentage raise to each employee's salary and then sum these amounts to find the answer.

Calculate Jane's raise: $41,100 * 0.04 = $1,644.

Calculate John's raise: $43,300 * 0.045 = $1,948.5.

Calculate Jack's raise: $39,900* 0.03 = $1,197.

Add the raises together to find the total: $1,644 + $1,948.5 + $1,197 = $4,789.5.

The closest amount to the total of all three raises is $4,790.

Answers

from 4:15 to 5:45 is a difference of 1:30 or an hour and 30 mins

1:30 x 30 = 3hours + 30mins + 30 mins + 30 mins

Rida and elisa are each paid by the hour. rida worked 5 1\2. hours and earned 77. elisa worked 3 3\4 HOURS AND EARNED 60. WHOSE HOURS RATE IS GREATER

Answers

Rida:
5 1/2 :77
5.5 : 77
Divide both sides by 5.5 to get $/hour:
1:14

Elisa:
3 3/4:60
3.75:60
Divide both sides by 3.75 to get $/hour:
1:16

16 is bigger than 14 so Elisa earns more.

Hope this helps :)

Final answer:

After calculating the hourly rates by dividing the total earnings by the hours worked, Elisa has a higher hourly rate of $16 per hour compared to Rida's $14 per hour.

Explanation:

To determine whose hourly rate is greater between Rida and Elisa, we need to calculate each person's hourly wage by dividing the total amount earned by the number of hours worked.

Rida's hourly rate calculation:

Total earned: $77Hours worked: 5.5 hours (since 1/2 hour is equal to 0.5 hours)Hourly rate: $77 / 5.5 hours = $14 per hour

Elisa's hourly rate calculation:

Total earned: $60Hours worked: 3.75 hours (since 3/4 hour is equal to 0.75 hours)Hourly rate: $60 / 3.75 hours = $16 per hour

Comparing the hourly rates, we find that Elisa's hourly rate is greater than Rida's.

A zoo kitchen's weekly grocery list shows the zoo orders 56pounds of each week . The zoo kitchen is the same number of pounds of bananas each day

Answers

I guess the answer is 56 it doesn't make sense

Final answer:

The zoo orders 8 pounds of bananas each day, calculated by dividing the weekly amount (56 pounds) by the number of days in a week (7).

Explanation:

The question specifies that the zoo kitchen orders 56 pounds of bananas each week. To find out how many pounds of bananas are ordered daily, we need to divide this weekly quantity by the number of days in a week. Since there are seven days in a week, 56 pounds of bananas divided by 7 equals 8 pounds. So, the zoo kitchen orders 8 pounds of bananas each day.

What is rounding up numbers?

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the number be represented as A

Now , the value of A is

A = 6,852

The number 6,852 rounded to the nearest thousand is

You rounded to the nearest thousands place. The 6 in the thousands place rounds up to 7 because the digit to the right in the hundreds place is 8

And , when the digit to the right is 5 or greater we round away from 0

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The state of Utah covers 82, 144 square miles.

The state of Montana covers 145, 552 square miles.

So, the total area of two states

= 145552 + 82144

= 2,27,696

A number has the digit 2,5,and4. To the nearest 100, the number rounds to 200. What is the number?

Answers

To start off we need to recognize that the number rounds to 200. This means that we need to choose the closest thing to 200, which would be the 2.

Now we know that the 2 goes in the hundreds place, there is only 2 digits left, 5, and 4. Now you can't put a 5 in the tens place because then it would round it up to 300 ( Anything greater than or equal to 5 gets rounded up) So that means that the 4 has to go in the tens place and the 5 in the ones place.

The final number ends up being:

245

The number with digits 2, 5, and 4 rounds to 200 when rounded to the nearest hundredh is 245.

What is rounding off of numbers?

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, A number has the digits 2, 5, and 4. To the nearest 100, the number rounds to 200.

Now if it rounds to 200 the first digit must be 2 so the number is either

254 Or 245.

254 rounds to 300 and 245 rounds to 200.

Using elimination solve 2x+7y=1 and 2x-4y=12

Answers

the workings are in the picture above

The solution to the system 2x + 7y = 1 and 2x - 4y = 12 is (- 1, 4).

What is the elimination method?

In the elimination method of solving two or more than two equations, we make one variable of both equations the same by multiplying or dividing and then we add or subtract them.

Given, 2x + 7y = 1 and 2x - 4y = 12.

If we subtract (2x + 7y = 1) - (2x - 4y = 12) we'll have,

7y + 4y = 1 - 12.

11y = - 11.

y = - 1.

Now putting the value of y in any one of these equations we get,

2x + 7(-1) = 1.

2x - 7 = 1.

2x = 8.

x = 4.

Is the value of the 3 in 6.832 ; 10, 1, or 1/10 times the value of the 3 in 112.3

Answers

1/10 because its 1 tenths place over

Answer:

1/10

Step-by-step explanation:

The place value of 3 in 6.832 is hundredth since 3 is located at the second position after the decimal point. Hundredth means 1/100

Similarly, The place value of 3 in 112.3 is a tenth since 3 is located at the first position in the value after the decimal from the back. Tenth means 1/10.

Since the value of 3 in 6.832 is 1/100, which is 1/10 of the place value of 3 in 112.3 i.e 1/10 of 1/10

The answer is therefore 1/10 since 1/10 of 1/10 gives 1/100
