Answer 1

Answer:

A. No

B. No

C. Yes

Step-by-step explanation:

A and B are either below or above 180 degrees when all angles degrees are added together

C is exactly 180 degrees when all angles degrees are added together

Answer 2

Answer:

A. No

B. No

C. Yes

Step-by-step explanation:

A is no because the triangles do not follow the Triangle Inequality Theorem, nor do the angles add up to 180°. The Triangle Inequality Theorem states that the sum of two angles must be larger than the third side.

100 + 40 + 20 = 160° (DO NOT ADD UP TO 180°)

40 + 20 = 60 (60 IS NOT GREATER THAN THE THIRD SIDE, WHICH IS 100).

B is no because the triangle does not follow the Triangle Inequality Theorem, nor do the angles add up to 180°.

20 + 80 + 100 = 200° (DOES NOT ADD UP TO 180°)

20 + 80 = 100 (100° IS NOT GREATER THAN THE THIRD SIDE, WHICH IS 100.)

C is yes because the triangle follows the Triangle Inequality Theorem and the angles add up to 180°.

50 + 60 + 70 = 180°.

60 + 70 = 130 (130 IS GREATER THAN 50).

70 + 50 = 120 (120 IS GREATER THAN 60).

A watering can contained 512 quarts water. After all the plants were watered, only 4 cups remained. How many cups of water were used to water the plants?

Answers

Answer:

2044 cups

Step-by-step explanation:

number of cups left = number of cups in the watering can - number of cups remaining

convert the capacity of the watering can to cups

1 quart = 4 cups

512 x 4 = 2048

2048 - 4 = 2044

70° + m<3 + 52° = 180°

m<3 = 58°

Answer:

A. 58°

Step-by-step explanation:

here's your solution

==> 70° + 52° + angle 3 = 180°. [linear pair]

==> angle 3 + 122° = 180°

==> angle 3 = 180° - 122°

==> angle 3 = 58°

Answers

Answer:

[tex]\frac{1}{5^6}[/tex]

Step-by-step explanation:

Given the expression (5⁻²)⁵ ₓ 5⁴

According to indices

(a^m)^n = a^{mn}

(5⁻²)⁵ = (5⁻¹⁰)

(5⁻²)⁵ ₓ 5⁴

= 5⁻¹⁰ ₓ 5⁴

= 5⁻¹⁰⁺⁴

= 5⁻⁶

Hence the equivalent expression is [tex]\frac{1}{5^6}[/tex]

The sum of two numbers is 147. The difference of the two numbers is 25.
What are the two numbers? Show your work.

Answers

86 and 61.

x + y = 147
x - y = 25

I always found second setting that second equation up was hardest. How do I know which one comes first? You just keep them in the same order as the first math equation.

So let’s solve for x in terms of y:
x - y = 25
x = 25 + y

Then substitute that into your first equation:
x + y = 147
(25 + y) + y = 147
2y = 122
y = 61

x = 25 + y = 25 + 61 = 86

Blank 1:
Question 101

Answers

30.66pi ft³

First, we need to find the volume of the cylinder using the following equation

[tex]V = r^2h\pi \\V = (2^2)5\pi \\V = (4)5\pi \\V = 20\pi[/tex]

The volume of the cylinder is 20pi

Next, we need to find the volume of a sphere. Since the cylinder is divided in half by the cylinder, we can use the following equation as if it were whole

[tex]V = \frac{4}{3} r^3\pi \\V = \frac{4}{3} 2^3\pi \\V = \frac{4}{3} 8\pi \\V = 10\frac{2}{3} \pi[/tex]

The volume of both half spheres is 10.66pi

Now we can add both together to get 30.66pi ft³

A restaurant owner wants feedback on the items on the menu, so she leaves a customer satisfaction survey on the tables for customers to

O A) convenience sample
OB) simple random sample
O C) stratified random sample
OD) voluntary response sample

Answers

Answer:

O A) convenience sample

Step-by-step explanation:

O A) convenience sample

The sampling method which describes the situation is option D. voluntary response sample.

What are Sampling Methods?

Sampling methods are methods used to select a sample using specific methods. This includes various types of probability sampling and non probability sampling methods.

This is included in the non probability sampling methods.

So it is either convenience sample or voluntary response sample.

Convenience sample is the selection of a sample which is convenient for you. That is, the sample which is most accessible is selected by the researcher.

Voluntary response sample is also the one which is most accessible. But the researcher is not selecting the sample. Instead the members of the population can decide whether to took part in the sample.

Here it is customer's wish to complete the survey.

So it is voluntary response sample.

Hence the correct option is D. voluntary response sample.

A monkey weighs 8.2 kilograms. How many grams does the monkey weigh? Use the number of zeros of the product when multiplying a number by a power of 10 to help you.

Answers

Answer:

m = 8.2 × 10³ grams

Step-by-step explanation:

Given that,

The weight of a monkey = 8.2 kilograms.

We need to convert its mass from kilograms to grams.

We know that,

1 kg = 1000 grams

1 kg = 10³ grams

In 8.2 kg,

8.2 kg = 8.2 × 10³ grams

Hence, the weight of the monkey is equal to 8.2 × 10³ grams.
