What is the correct answer

Mathematics
1 answer:
saw5 [17]3 years ago
8 0

Since the total number of songs is 46,

g + d = 46

This is the first equation.

Since the guitarist wrote 8 less than twice the number of songs written by the drummer,

g = 2d - 8

This is the second equation.

Therefore, the answer is F.

What is the value of R in this circuit
goblinko [34]

See that messy ugly fraction on the right side of the equation ?  Let's make it easier to write.  

If we multiply the top and bottom of the fraction by the same thing, we won't change the value of the fraction.  Let's multiply top and bottom by <em>R</em> .

The fraction 1 / (1/R + 1/2R)

Multiply top and bottom by R :

The fraction = R / (1 + 1/2) .  

But that's just  R/1.5 .

So 20 = R/1.5

Multiply each side of this equation by 1.5 , and you have . . .

<em>30 = R</em>

<em></em>

This is not even a problem about electrical circuits or resistors.  This is a problem about handling complicated fractions to make them less messy.

Find the highest common factor of 12 and 40<br>​
levacccp [35]

To find the highest common factor (HCF) between two numbers , first to take HCF of both the numbers.

\purple {\Large\begin{array}{r | l}2&\underline{12}\\3& \underline{6}\\2&\underline{2}\\&\underline{1}\\\end{array}} \:  \:  \:  \:  \:  \:  \:  \:   \:  \: \:  \: \purple {\Large\begin{array}{r | l}2&\underline{40}\\2& \underline{20}\\5&\underline{10}\\2&\underline{2} \ \\ &\underline{1}\\\end{array}}

  • Take every common prime factor between 12 and 40

\red {\large \implies} \large \: 12 \:  =  \: 2 \:  \times  \:  3 \:  \times  \: 2 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \red {\large \implies} \large \:40 \:  =  \: 2 \:  \times  \: 2 \:  \times  \: 5 \:  \times  \: 2 \:

  • Finally, identify the factors common to each number and multiply those common factors together.

\rm\orange {\large \implies} \large \:Common \:   factors \: =  \: 2 \:  \times  \: 2

\rm\orange {\large \implies} \large \:HCF = 4

Dayami works at Future Shop and earns $10.50/h plus 6% commission on sales. Last
skad [1K]
<h2><u>Quick answer</u> :</h2>

= \tt\$570

<h2><u>Answer with steps</u> :</h2>

Money Dayami earns for an hour's work = $10.50

Number of hours Dayami worked last week = 40

Money Dayami would have gotten for her work :

=\tt 10.50 \times 40

=\tt  \$ \: 420

Thus, money earned by Dayami for her work = $420

Total sales Dayami made last week = $2050

Money Dayami must have earned as commission :

= 6% of total sales

= \tt6 \% \: of \: 2500

=  \tt\frac{6}{100}  \times 2500

=\tt  \frac{15000}{100}

=\tt \$150

Thus, money Dayami earned as a commission = $150

Dayami's weekly gross salary last week :

= \tt420 + 150

=\color{plum} \tt \: \$570

Thus, total salary = $570

Therefore, Dayami's gross salary last week =<u> $570</u>
