Lana runs a business where she fixes bikes. She charges $15.75 per hour for her labor as well as a $25 flat fee for any parts sh

Masja [62]

Answer:

y = 15.75x + 25 is the linear equation

$88 would be the total cost

Step-by-step explanation:

First, create the equation using y = mx + b, where x is the number of hours:

y = 15.75x + 25 will be the equation, since the charge is $15.75 per hour and the flat fee is $25

There are 4 hours in between 8:30 AM and 12:30 PM, so to find the cost, plug in 4 as x and simplify:

y = 15.75x + 25

Plug in 4 as x:

y = 15.75(4) + 25

y = 63 + 25

y = 88

So, the total cost would be $88

Find each number. Round to the nearest tenth if necessary

Pavel [41]

Answer:

96
6.9
25%
8%
79
33.8

Step-by-step explanation:

Here is the complete question: Find each number. Round to the nearest tenth if necessary.

80% of 120.
115% of 6
What percent of 128 is 32?
3 is what percent of 36?
23.7 is 30% of what number?
71/2% of what is 12?

1) 80% of 120

= $\frac{80}{100} \times 120= 8\times 12$

= 96

∴ 80% of 120= 96

2) $115\%\ of\ 6$

= $\frac{115}{100}\times 6= 1.15\times 6$

∴ $115\%\ of\ 6$ = 6.9

3) What percent of 128 is 32?

= $\frac{32}{128} \times 100$

= $25\%$

4) 3 is what percent of 36?

= $\frac{3}{36} \times 100$

= $8\%$

5) 23.7 is 30% of what number?

Let the number be "x".

⇒ $\frac{30}{100} \times x= 23.7$

Cross multiplying

⇒ $x= \frac{23.7\times 100}{30}$

∴ x= 79.

6) 71/2% of what is 12?

Lets assume the required number be "x".

⇒ $\frac{71}{2} \times 100\times x= 12$

cross multiplying both side.

⇒x= 33.8

∴ 71/2% of 33.8 is 12

The first term of an arithmetic sequence is equal to four and the common difference is three. find the formula for the value of

hichkok12 [17]

The formula for the value of nth term is $a_{n}$ = 3n + 1

Step-by-step explanation:

The formula of the nth term in the arithmetic sequence is

$a_{n}=a+(n-1)d$ , where

a is the first term of the sequence
d is the common difference between each two consecutive terms

∵ The first term of an arithmetic sequence is equal to four

∴ a = 4

∵ The common difference is equal to three

∴ d = 3

- Substitute these values in the rule of the nth term

∵ $a_{n}=a+(n-1)d$

∴ $a_{n}=4+(n-1)3$

- Simplify it

∴ $a_{n}=4+3n-3$

∴ $a_{n}=1+3n$

The formula for the value of nth term is $a_{n}$ = 3n + 1
