Answer:

11 am

Step-by-step explanation:

Bus A and Bus B leave the bus depot at 9 am.

Bus A takes 30 minutes to complete its route once

Bus B takes 40 minutes to complete its route once.

We solve this finding the Lowest Common Multiple of the minutes each bus uses to complete it's route

30 = 3 × 10

40 = 4 × 10

= 3 × 4 × 10

= 120 minutes

120 minutes after 9 am is

60 minutes = 1 hour

60 minutes = 1 hour

= 2 hours.

9am + 2 hours

= 11 am.

Therefore, they be back at the bus depot together at 11 am

Answer:

\frac{AB}{BC} = \frac{CE}{ED}

Step-by-step explanation:

Given

The attached proof

Required

Complete the missing piece

In (a), we have:

\triangle ABC \to \triangle CED

This implies that, the following sides are similar:

AB \to CE

AC \to CD

BC \to ED

An equation that compares the triangle can be any of:

\frac{AB}{BC} = \frac{CE}{ED}

\frac{AB}{AC} = \frac{CE}{CD}

.....

From the options;

\frac{AB}{BC} = \frac{CE}{ED} is true

Explain your answer plez
tiny-mole [99]

Answer:

50°

Step-by-step explanation:

In a parallelogram, opposing angles must be equal.  Note how 75° = 75°.  Thus, opposing angles 2x + 5 and x + 55 must also be equal.

Solve this equation for x.

Subtracting x from both sides yields x + 5 = 55.  Next:  Subtracting 5 from both sides yields x = 50° (answer choice C)

Classify the real number. (Choose all that apply). –9 A.) Rational B.) Whole C.) Irrational D.) Natural E.) Integer
IRISSAK [1]
Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.

natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.

integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.

rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.

irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.


so your answer is integer and rational, hope this helped! :)

Which inverse operation would be used to verify the following equation? 102 ÷ 3 = 34
MA_775_DIABLO [31]
An inverse operations is the reverse of the equation. For example, since it's 102 ÷ 3 = 34, to get the inverse you would take the opposite sign of "÷" and make it "×," while changing the equal sign to make the statement true. The inverse operation used to verify this is 102 = 3 × 34
