Answer:

x = 22

Step-by-step explanation:

The sum of the angles round a point is 360°

Sum the given angles and equate to 360

x + 6x + 40 + 3x + 100 = 360

10x + 140 = 360 ( subtract 140 from both sides )

10x = 220 ( divide both sides by 10 )

x = 22

Natali5045456 [20]

Answer:

The money left after gasoline expenses was $622.50.

Step-by-step explanation:

Given:

Last month, family had used 40% of the monthly income for gasoline, and 63% of that gasoline was consumed by the family's SUV.

The family's SUV used $261.45 worth of gasoline previous month.

Now, to find the money left of the family monthly income after gasoline expenses.

Let the total money spend on gasoline be $g.$

As, given:

The family's SUV used $261.45 worth of gasoline, which was 63% of the gasoline that was consumed.

According to question:

$63\%\ of\ g=$261.45.\\\\$

$\frac{63}{100} \times g=261.45\\\\0.63\times g=261.45$

Dividing both sides 0.63 we get:

$g=\$415.$

The total money spend on gasoline = $415.

Now, 40% of the monthly income is used for gasoline.

Let the total monthly income be $x.$

So, to get the monthly income we put an equation:

$40\%\ of\ x=\$415\\\\\frac{40}{100}\times x=415\\\\0.40\times x=415$

Dividing both sides by 0.40 we get:

$x=\$1037.50.$

The total monthly income = $1037.50.

Now, to get the money left after gasoline expenses we subtract the total money spend on gasoline from the total monthly income:

$\$1037.50-\$415\\\\=\$622.50.$

Therefore, the money left after gasoline expenses was $622.50.

Answer:

hello your question lacks the required statements here are the statements

A spinner is divided into four sections of equal size, numbered 1, 2, 3, and 4. You spin it three times, and get 1, 4, and 3. Which statement is FALSE?

A. The theoretical probability of a 1 is 25%.

B. The experimental probability of a 1 is 25%.

C. If you spin the same spinner again and get different results, the experimental probabilities are different, but the theoretical probabilities have not changed.

D. The experimental probability of a 2 is 0%.

Answer : The experimental probability of a 1 is 25% ( B )

Step-by-step explanation:

The first statement is true because since the spinner is divided into 4 sections the theoretical probabilty is equal for all sections i.e 25% each

The second statement is false because after spinning the spinner three times ( experimental ) the results obtained were 1,4,3 hence the experimental probability of 1 would be 33.3%

the theoretical probabilities remains unchanged but the experimental probabilty can change

the experimental probabilty of 2 is 0% because after the 3 experiments the number 2 did not show up
