Derrick really wants to earn at least $330 at the Bike Shop. He earns $150 per week plus $15.50 for each bicycle that he assembles. How many bikes will he need to assemble this week in order to earn at least $330? (be careful when rounding in a real world problem to make sure that your answer works) Question 1 options: 10 bikes , 11 bikes , 12 bikes , 13 bikes

Answers

Answer: He will need to assemble 12 bikes, because 12 x 15.50 = $186 and $186 + 150 = $336

Step-by-step explanation: Don't need one :)) it's basic math

330-150= 180 then divide 180 by 15.50 and you will get 11.6129 and you can round that to 12 bikes

Step-by-step explanation:

Divide 280 by 4/5 and get 14 then multiply by 4 and get 56

Answer:

1400 ft2

Step-by-step explanation:

if 280 ft2 comes from 4/5 of 1 gallon of paint, then do 280 x 4, because their are 4 gallons of paint. after you x that it will be 1120 ft2. but the extra 1/5 paint from all 4 of the gallons comes out to 4/5 so add 280 ft2 to that 1120 ft2.

it comes out to 1400 ft2.

Enola spent $48 at a used book store where hardback books sell for $12 each and paperback books sell for $8 each.

A. Write an equation in standard form where x represents the number of hardback books and y represents the number of paperback books she bought that day:




B. If she bought 2 hardback books how many paperback books did she buy?

Answers

Answer:

A. 48= 12x + 8y

B.  3 paper back books

Step-by-step explanation:

A. If x represents hardback book, and they are $12 each then that is 12x. y = the paperback books that are $8 each, so 8y. and 48 is the amount that Enola spent.

B. 2 hardback books would equal $24.  If you had 3 paperback books that would equal $24. And the two together to get the total amount of $48.

Create a proportion using the form = to represent the following word problem.

78% of what number is 42?

Answers

Answer :
x = 53.85

Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.

1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42

2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85

3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :

42/0.78 = 53.85
To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 42 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 42 is 100%, so we can write it down as 42=100%.
4. We know, that x is 78% of the output value, so we can write it down as x=78%.
5. Now we have two simple equations:
1) 42=100%
2) x=78%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
42/x=100%/78%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 78% of 42

42/x=100/78
(42/x)*x=(100/78)*x - we multiply both sides of the equation by x
42=1.28205128205*x - we divide both sides of the equation by (1.28205128205) to get x
42/1.28205128205=x
32.76=x
x=32.76

Which inequality describes all the solutions to -3(4 – x) + 6 < 9 – 2x?

Answers

Answer:

To do inequalities, you just need to solve the equality and then figure out what side (higher or lower) the solution is on and put in the appropriate greater-than, less-than, greater-than-or-equal-to or less-than-or-equal-to sign.

 

Think about the equality for this one. What equation could we right for the average number of words per week that would put Trevor right at 50,000 after 5 weeks.

 

If we call the number of words per week, w, we would have

 

w = [an expression]   (You find the expression using the number of words he has to write and how many weeks he has.)

 

Now think about the inequality. Trevor wants to finish in five weeks or less. So as long as he writes at least this number of words per week, he'll make it. That means we want a greater-than-or-equal to sign:

 

w ≥ [your expression]

Step-by-step explanation:

The inequality which describes all the solutions to the inequality is

x < 3

Given the inequality expression given as -3(4 – x) + 6 < 9 – 2x, we need to find the solution to the system of inequality as shown:

[tex]-3(4 -x) + 6 < 9 - 2x[/tex]

Expand the bracket

[tex]-3(4 -x) + 6 < 9 - 2x\\-12+3x+6<9-2x\\3x-6<9-2x\\3x+2x<9+6\\5x<15\\x<15/5\\x<3[/tex]

Hence the inequality which describes all the solutions to the inequality is

x < 3

A store sells a hoodie for $45, the sales tax rate in this state is 8%. What is the total price with sales tax applied?

Answers

The answer is $48.60.

The hoodie by itself has a price of $45. If the sales tax if 8% of the price you’d have to calculate the sales tax and add it to the net amount.

(45)(.08) = 3.60

(45) + 3.60 = 48.60
$48.60. multiply 45 by 0.08 to find the tax, which is $3.60. add the price plus the tax and you have the end price, which is $48.60

Thomas decides to use the method of proportions and similar
triangles to find the height of a lamppost. He measures the length of
the post's shadow and finds it is 5 feet long. Then, he holds a 1-foot
ruler perpendicular to the ground and finds that it casts a 2-inch
shadow. How tall is the lamppost?
a. 2.5 ft c. 30 ft
b. 12 ft d. 60 ft

Answers

Answer:

The lamppost is 30 ft tall.

Step-by-step explanation:

You need to draw a diagram of the problem. Refer to attachment.

Now you need to convert the measurements that are in feet to in. The 1 foot ruler is now 12 in. and the 5 foot post's shadow is now 60 in.

The next step is to create a proportion between both angles. [tex]\frac{x}{1} =\frac{60}{2}[/tex]

x over 1 is simplified to x and 60 divided by 2 is just 30. So the lamppost is 30 ft tall.
