.

Answers

Answer 1

Answer:

mike's estimated the difference was 72, the actual difference is 72.74

hoped this helped!

Answer 2

Answer:

Mike estimated the difference to be 72
The actual difference is 72.74

Step-by-step explanation:

When mike rounded, 79.44 became 79 and 6.7 became 7

79.44 rounds to 79 because 0.44 is less then 0.5
6.7 rounds to 7 because 0.7 is greater then 0.5
so 79 - 7 = 72

The actual difference is 79.44 - 6.7 = 72.74
                           
 79.44
-   6.70
------------

  72.74

and y -intercept(b) = 7

now,

y = mx+b

Using the diagram below, determine which statement is NOT true.

Answers

Answer:

C. Angles X and Z are supplementary

Step-by-step explanation:

A: This is true because in Angle Y, a right angle is shown. A right angle is worth 90°.

B: This is true because X, Y, and Z are supplementary (add to 180), and given that Angle Y is 90 degrees, 180 - 90. Thus, they're complementary.

C: This is false and the correct answer choice because Angle Y exists too. Angle X and Z, added together, would make 90 degrees, not 180.

D: This is true because Angles Y and Z are right next to each other, and that's what adjacent means.

Therefore, the answer is C.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

C. angles x and z are supplementary

Step-by-step explanation:

Supplementary angles add up to 180 degrees. Because a line presents a 180 degree angle, and y equals 90 degrees angle x plus angle z would be 180-90 degrees which is 90, not 180 which would make them complementary

17. Kayla consumed 1800 calories on Monday. She consumed 500 more calories on Tuesday than she did on Wednesday, she consumed 100 calories less than she had on Tuesday. Find the rate of change in calorie intake from Monday to Wednesday.

Answers

Since we are asked to find the rate of change from Monday to Wednesday, we are dividing by 2, since Monday is day 1 and Wednesday is day 3. 3 - 1 = 2.

1800 + 500 = 2300 calories consumed Tuesday.

2300 - 100 = 2200 calories Wednesday.

(2200 - 1800)/2 = 400/2 = 200 calories  

Monday/1800cal
Tuesday/2300cal
Wednesday/2200

It is 3 whole days: All of Monday, all of Tuesday, and ALL of Wednesday.
Rate of change = (2200-1800)/3 = 400/3 = 133 and 1/3

How can 1% of 600 be used to determine 36% of 600? Enter your answers in the boxes to correctly complete the statement.




1% of 600 is _ so 36% of 600 is_.​

Answers

Answer:

1% of 600 is 6, do 36% of 600 is 216.

Step-by-step explanation:

Simply change the percentages to decimals and multiply.

1% = 0.01

36% = 0.36

Hope it helps! :)

Answer:

1% of 600 is 6, so 36% of 600 is 216.

Step-by-step explanation:

1% of 600 be used to determine 36% of 600 by multiplying 36 to 1% of 600.

1/100 x 600 = 1% of 600=> 1 x 6 = 1% of 600=> 6 = 1% of 600

Now, multiply this by 36 to get 36% of 600.

6 x 36 = 1 x 36% of 600  => 216 = 36% of 600  

Hence, 1% of 600 is 6, so 36% of 600 is 216.
