A. 53°
B. 43°
C. 37°
D. 27°

Answers

Answer:

43.

Step-by-step explanation:

∠1 and ∠4 are vertical angles.

Vertical angles are equal.

Therefore,  

m∠1 = m∠4 = 43°

The measure of angle m is 53°

What is an angle?

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays.

Given is a figure, with two parallel line are intersected by a transversal line,

The angles 1 and 4 are vertical angles, and we know that vertically opposite angles are equal,

Therefore,

m ∠ 1 = 53° = m ∠ 4

Hence, the measure of angle m is 53°

I don’t need the definition I just want someone to make me understand in a simple way like a tutor, but anyways please help me understand this. Examples would work, anything. Just help me understand. Thanks anyways.

Answers

Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

Step-by-step explanation:

Harvey is working on a weekly budget. He earns $459 per week. Harvey spends $200 per week on rent and utilities plus $85 per week on food. After paying for rent, utilities, and food, Harvey deposits 2/3 of the amount left over into a savings account. He can spend the rest of the money on entertainment.
How much money does Harvey have to spend on entertainment per week?

Answers

Answer: Harvey has $174 per week to spend on entertainment.

Step-by-step explanation: first Add the money he has throughout the week which is $200 + 85 =285 and just subtract $459 and 285.

A fraction is a way to describe a part of a whole. The money that Harvey has to spend on entertainment per week is $58.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Harvey earns $459 per week and spends $200 per week on rent and utilities, also $85 per week on food. Therefore, the amount of money left with Harvey,

Amount left with Harvey

= Earning - spending on rent and utilities - spending on food

[tex]\text{Amount left with Harvey} = \$459 - \$200 -\$85 =\$174[/tex]

From the leftover money, Harvey deposits 2/3 of the amount leftover into a savings account. therefore, the amount in the saving account is,

[tex]\text{Amount in the saving account} = \dfrac23 \times (\text{Amount of money left})[/tex]

                                                [tex]= \dfrac23 \times ($174)\\\\=\$116[/tex]

Now, the amount left for spending on entertainment is,

[tex]\text{Amount left for spending on entertainment} = \$174 - \$116 = \$58[/tex]

Hence, the money that Harvey has to spend on entertainment per week is $58.
