Kendra says that she can draw <A and <B so that m <A is 119° and <A and <B are complementary angles. do you agree or disagree? explain your reasoning.

Answers

Answer 1

Answer: I disagree, because if angle A and B make complementary angles then both the measures added should equal 90 degrees. However, m<A is 119 so it cannot be complementary making the statement false.

If the sides of two similar triangles are in the ratio of 3:5, find the ratio of their areas.

Answers

Ratio of areas of similar triangles is 9 : 25.

Solution:

Given data:

Ratio of sides of two similar triangles = 3 : 5

To find the ratio of areas of the triangles:

We know that,

In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.

$$\text{Ratio of areas} = \frac{\text{Area of triangle 1}}{\text{Area of triangle 2} }$

$$=\left((3)/(5)\right) ^2$

$$=(9)/(25)$

Ratio of areas of similar triangles is 9 : 25.

Answer:

Explanation:

Scale factor for the sides of these triangles.

Therefore the ratio of area will be:

Area Triangle A

Area triangle B

1) Mr. Adams had 24 guests at his house for a party. Each guest brought one item. - One-third of the guests brought drinks.

- One-fourth of the guests brought a dessert.

- The rest of the guests brought chips.

How many guests brought chips?

Answers

10 guests brought chips. To find the total number of guests who brought each item, all you need to do is divide 24 by the number in the fractions denominator. Then, add your answers and subtract them from 24 to get the total number of guests who brought chips.

24 / 3 = 8
8 guests brought drinks.

24 / 4 = 6
6 guests brought desserts.

6 + 8 = 14
24 - 14 = 10
10 guests brought chips.

Hope this helps!

Answer: The answer would be 10 guests brought chips

Which numbers are solutions to the inequality x < −7, using the replacement set {−15, −10.5, −7.2, −7, 0}?Choose all answers that are correct.

A.
–7

B.
−7.2

C.
−10.5

D.
−15

Answers

The correct answers are B, -7.2, C, -10.5, and D, -15. The inequality x < -7 means that x is less than -7. Keep in mind that the larger a negative number appears to be, the smaller a number it actually is. For example, if you were 1 dollar in debt, then you would have more money than if you were 100 dollars in debt.

x < -7 Given
-7 < -7 Substitute for answer choice A
This inequality is untrue, because -7 is equal to -7.

-7.2 < -7 Substitute for answer choice B
This inequality is true, because -7.2 is less than -7.

-10.5 < -7 Substitute for answer choice C
This inequality is true, because -10.5 is less than -7.

-15 < -7 Substitute for answer choice D
This inequality is true, because -15 is less than -7.

Hope this helps!
