Aiden's mom calculated that in the previous month, their family had used 40% of the monthly income for

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.

On her birthday, Sonia distributed chocolates in an orphanage. She gave 5 chocolates to each child and 20 chocolates to adults.

qwelly [4]

Answer with explanation:

Total number of Children = x Children

Total number of chocolates distributed = y Chocolates

If there are x children, then total number of chocolate got by children= 5 x Chocolate

Number of chocolate got by Adults= 20

Let total number of adults be z.

Expressing the statement in terms of Equation

y = 5 x + 20 z

$z=\frac{y-5 x}{20}$

⇒Number of Adults =z

$=\frac{y-5 x}{20}$

Assuming, it's decimal logarithm.

<h3> $\log\sqrt{30}-\log\sqrt6+\log\sqrt2=\log\dfrac{\sqrt{30}\cdot\sqrt2}{\sqrt6}=\log \sqrt{10}=\dfrac{1}{2}\log 10=\dfrac{1}{2}\cdot 1=\dfrac{1}{2}$ </h3>
