Answer:

28 minutes

Step-by-step explanation:

40 percent is 0.4 and 100 percent is 1. Since you have the full 100% of 20 plus the increase of 40% you have to multiply by 20 by 1.4

1.4*20 = 28

Mark this question "True" if the argument is VALID, and "False" if the argument is INVALID: If this number is larger than 6, the
sleet_krkn [62]

This argument is no valid although the first part of the statement is valid. If a number is larger than 6 than its square must be larger than 36. But if the number is smaller than 6, its square does not need to be smaller than 36. For example...

(-100)²=10000

-100 is smaller than 6 but its square is bigger.

answer: False

In the following equilateral triangle,<br> each angle has a measure of 10x + 20.<br><br> X=[? ]
maria [59]

Answer:

4°

Step-by-step explanation:

All the angles in a triangle add together to equal 180°. We know there are three angles of 20° so let's subtract this.

20° × 3 = 60°

180° - 60° = 120°

Now well divide 120° up among the three angles.

120° ÷ 3 = 40°

Now we know the angles are 40° + 20°, but we need to find the value of x, so divide 40° by 10

40° ÷ 10 = 4°

x = 4°

(8 × 7 − 3) × 7 Match each expression to another expression with the same value
kodGreya [7K]

Hey there!

(8 * 7 - 3) * 7

= 8(7)(7) - 3(7) ⬅️ POSSIBLY BE AN EQUIVALENT EXPRESSION

= 56(7) - 3(7)

= 392 - 3(7)

= 392 - 21

= 371 ⬅️ OVERALL ANSWER/EQUATION ANSWER

Most likely your answer should be:

• 8(7)(7) - 3(7)

• 56(7) - 3(7)

• 392 - 3(7)

• 392 - 21

EITHER OF THESE SHOULD WORK ⬆️

Good luck on your assignment and enjoy your day!
