Answer 1

Answer:

13.5 minutes

Step-by-step explanation:

We can divide the final temperature to the rate of change to find the time it will take.

-10.8 ÷ -0.8 = 13.5

Check if needed.

13.5 * -0.8 = -10.8

Best of Luck!

Answer 2

Answer: 13.5 minutes

Step-by-step explanation:

We have to divide the temperature you need to reach by the temperature than rate changes at every minute.

-10.8 ÷ -0.8 = 13.5

The answer is 13.5 minutes. Hope this helps!

Answer:

It is the total cost of the membership fee and the tire pressure check for 12 months.

Step-by-step explanation:

given data

Membership Fee: $50

Cost: $4 per car per month

Washing Cost: $10 per car per month

Tire Replacement Cost: $400 per car Tire Pressure Check Cost: $15 per month

let the total cost be y

and the number of cars be n'

and the number of months be x

the model for the situation is given as

y=50+4nx+10nx+15

from the expression above the constant term is the total cost of the membership fee and the tire pressure check for 12 months.

9(42) - 9(4) = 9(30) - 9(___)

Answers

Answer: 8 (I might have gotten it wrong tho) could be -8 too btw.

Step-by-step explanation:

42x9=378 and 9x4=36. 9x30=270 so that would make the equation 378-36=270-9(_). Simplified a bit more would be 342=270-9(_). Now subtract 270 from both sides you get 72=9(_) so it would be 8. Sorry if I’m wrong tho.

Answer:

9(42) - 9(4) = 9(30) - 9(-8)

Step-by-step explanation:

9(42 - 4) = 9(38)

9[30 - (-8)] = 9(38) because of rules of subtracting integers is:

The total fare (F) for x kilometers given that Php 50.00 is paid for the first 10 kilometers and the addition of Php 5.00 for every succeeding kilometer.

Answers

Given:

Php 50.00 is paid for the first 10 kilometers and the addition of Php 5.00 for every succeeding kilometer.

To find:

The total fare (F) for x kilometers.

Solution:

Let x be the number of kilometers and F(x) is total fare.

Number of kilometers cannot be negative. So, x is always greater than 0.

Php 50.00 is paid for the first 10 kilometers.

[tex]f(x)=50.00[/tex] for [tex]0\leq x\leq 10[/tex]

The addition of Php 5.00 for every succeeding kilometer.

[tex]f(x)=50.00+5.00(x-10)[/tex] for [tex]x\geq 10[/tex]

Therefore, the required function is

[tex]\begin{cases}50.00, & \text{ if } 0\leq x\leq 10\\ 50.00+5.00(x-10), & \text{ if } x\geq 10 \end{cases}[/tex].

the square root of 66 is between 8.12 and _,and it is closer to_

Answers

Answers:

Square root of 66 is between  8   and  9  

It is closer to  8  

===================================================

Explanation:

Note that 66 is between the perfect squares 64 and 81

So we can say the following:

[tex]64 < 66 < 81\\\\\sqrt{64} < \sqrt{66} < \sqrt{81}\\\\8 < \sqrt{66} < 9[/tex]

Meaning the square root of 66 is between the integers 8 and 9.

The decimal approximation of 8.12 helps confirm this (because 8.12 is between 8 and 9).

------------------

[tex]\sqrt{66}[/tex] is closer to 8 than it is to 9 since 66 is closer to 64, than 66 is to 81.

Also, we're told that [tex]\sqrt{66} \approx 8.12[/tex] giving us more proof that [tex]\sqrt{66}[/tex] is closer to 8.

Step-by-step explanation:

The interest earned is given by the formula ...

  I = Prt

For the reference amount, that is ...

  I = ($150)(0.04)(2) = $12

For the choices, the earned interest amounts are ...

  1) ($300)(.02)(2) = $12

  2) ($150)(.06)(1.5) = $13.50

  3) ($400)(.03)(1) = $12

  4) ($100)(.01)(8) = $8

  5) ($50)(0.48)(0.5) = $12

Accounts 1, 3, 5 would earn the same interest.

6. 24.08

7. 17.32

8. 15.81

9. 16.85

10. 28.17

Step-by-step explanation:

The square root of the numbers to the nearest hundredth is:

√138= 11.75

2. √405=20.12

3. √800= 28.28

4. √1150= 33.91

5. √6500= 80.62

6. √580= 24.08

7. √300= 17.32

8. √250= 15.81

9. √284= 16.85

10. √794= 28.18

The square root of a number is a value that when multiplied by itself it gives the number, For example, the square root of 16 is 4. This is because 4 x 4 = 16

Square root is denoted with this symbol √

In order to round off to the nearest hundredth, look at the number in the thousandth place, if the number is equal or greater than 5, add 1 to the hundredth value. If this is not the case, add zero to the hundredth value.

√138= 11.75

2. √405=20.12

3. √800= 28.28

4. √1150= 33.91

5. √6500= 80.62
