A conversion table indicates that 1 mile is 1.6 km. With this conversion rate, is the speed limit greater than or less than 65 mph? Explain.

Answers

greater because 1.6 is larger than 1

Answer:

higher than

Step-by-step explanation:

The speed limit is 110 km hour and there are 1.6 kilometers in a mile. This means that there are 110 ÷ 1.6 miles per hour:

110 km hour÷1.6 km mile=110÷1.6 miles hour.

We can find 110 ÷ 1.6 using long division and it is 68.75. So the speed limit is higher than 65 mph

Answers

Answer:

Step-by-step explanation:

4x + 6 = 102

-6. -6

4x= 96

x=24

Sum of all angles of triangle=180°

So, 102 + 4x + 6 + x = 180

or 5x + 108 = 180

or 5x = 180 - 108

or 5x = 72

or x = 72/5

or x = 14.5

So, x = 14.5°

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

What is the equation of this line? Please help I will give extra points and the brain thing.

y=−3x−4/3

y=4/3x−3

y=3/4x−3

y=−3x−3/4

Answers

The equation of this line is y= 3/4x - 3
Because the y intercept is -3 and the slope is rise 3 run 4 making it 3/4. It is a increasing line so it has a positive slope

y=3/4x -3. You find the slope which is rise 3 and run 4 so it’s 3/4. Then the y intercept is already given to you since it’s just where the slope crosses the y axis. Y intercept is -3.

Juan and Gloria are comparing the two numbers 354.6 and 354.06. Juan says that 354.06 is equal to 10 x 354.6. Gloria says he is wrong. Do you agree with Juan or Gloria? Explain your thinking.

Answers

I agree with Gloria because Juan’s answer would be 3546.6. If you multiply any number by 10 it is moving to decimal 1 place to the right so as an example 354.06 multiplied by 10 would be 3540.6 because you moved the decimal to the right one number.

Juan is incorrect; Gloria is right. 354.06 is not equal to 10 times 354.6 as the zero only changes the decimal place value.

Gloria is accurate while Juan is mistaken. 354.6 and 354.06 do not add up to the same number. It is not possible to get a value that is 10 times the other number (354.6) by adding a zero to the decimal point (354.06).

Only the decimal place value is altered when a zero is added the actual numerical value remains unchanged. Compared to 354.6, which only has one decimal place, 354.06's additional zero after the decimal point indicates a more accurate measurement. Juan was mistaken when he said that 354.06 was equal to 10 times 354.6.
