A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 20 child bikes and 6 adult bikes in the week.
No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answers

Answer 1

20(4) +6(6) = 80 +36 = 116 total building time

20(4) +6(4) = 80 +24 = 104 total testing time ( this is greater than the allowed 100 hours)

Answer:

[tex]\frac{5\sqrt[3]{6}}{8}[/tex]

Step-by-step explanation:

We have been given an exponential number. We are supposed to simplify our given number.

[tex](\frac{750}{512})^{\frac{1}{3}[/tex]  

Using fractional exponent rule [tex]x^\frac{m}{n}=\sqrt[n]{x^m}[/tex], w ecan write our given number as:

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{(\frac{750}{512})^1}[/tex]

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{750}{512}}[/tex]

We can rewrite 512 as [tex]8^3[/tex] and 750 as 125*6.

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{125*6}{8^3}}[/tex]

We can rewrite 125 as [tex]5^3[/tex]

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{5^3*6}{8^3}}[/tex]

Using radical rule [tex]\sqrt[n]{a^n}=a[/tex], we will get:

[tex](\frac{750}{512})^{\frac{1}{3}}=\frac{5\sqrt[3]{6}}{8}[/tex]

Therefore, [tex]\frac{5\sqrt[3]{6}}{8}[/tex] is equivalent to our given number.

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −8 to x = −2.
A)−1
B)−3
C)1
D)3

Answers

In order to find the average rate of change, we must take the values at x=-8 and x= -2, and determine what the slope would be if a line was drawn between the two points. 
f(-8) = -8² +9(-8) + 18
f(-8) = 10

f(-2) = -2² + 9(-2) + 18
f(-2) =4 -18 +18
f(-2) = 4

f(-8) =10 and f(-2)=4

if a line was drawn between the two points (-8,10) and (-2,4) the slope (rise/run) would be -6/6, since the line would go down 6 units from 10 to 4, and over 6 units from x=-8 to x=-2.

The average rate of change, therefore, is -6/6, or
A)-1

What is the value of k?

2k+9=7−3k

Answers

To find the value of k in the equation 2k+9=7−3k, we rearrange and simplify to isolate k, resulting in k = -2/5.

To solve for the value of k in the equation 2k+9=7−3k, we must isolate the variable on one side of the equation. Let's start by adding 3k to both sides to get all the k terms on one side:

2k + 3k + 9 = 7 − 3k + 3k
5k + 9 = 7

Next, subtract 9 from both sides to get:

5k = 7 − 9
5k = −2

Now, to find the value of k, divide both sides by 5:

k = −2/5

Therefore, the value of k is −2/5.

Slope is 3, and (1,4) is on the line

Answers

The first step is since you know what the slope is, you can just plug that into the equation. We now have y=3x+b, b being the y intercept.
3 is equal to 3/1, and you can use that to find the Y intercept. Start at the point that they game you and go up 3 and over 1. But this makes you further away from the Y axis, so you want to do the opposite. Go down 3 and over 1.\
This makes you end up on the Y intercept at (0,1)
Making the equation y=3x+1
Hello!

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second.

3 ft = 1 yd

5280 ft = 1 mi

How much faster does the fish swim than the boy in yards per minute?

Answers

The Boy: 4.4 x 60 = 264ft per minute.  264 / 3 = 88yrds Per minute

The Fish: 12 x 5280 = 63360ft hr. 5280 / 60 = 1056ft minute 1056 / 3 = 352yrds

352 - 88 = 44 yards quicker then the boy.

44 x 3 = 132 feet quicker then the boy.

First, you convert 12 miles per hour into yards per hour:
21120 yards per hour.

Then you convert 4.4 feet per second into yards per second:
1.47 yards per second.

Then convert 1.47 yards per second into yards per hour:
5292 yards per hour.

Subtract 5292 from 21120:
15828 yards per hour.

Then convert that into minutes:
263.8 yards per minute.

The fish is 263.8 yards per minute faster than the boy.

Brandon says to get that shade of green, 6 pints of yellow paint need to be added to the bucket. Bianca says that won't work. In two or more complete sentences, explain who is correct and why. In your explanation, include the calculations to support the correct answer.

Answers

There are 2 pints of blue and 2 pints of yellow in the bucket.
To be 80% yellow, the new color will be (100%-80%=) 20% blue.

2 pints is 20% of (2 pints/0.20=) 10 pints. 
With 4 pints in the bucket, to make 10 pints you should add 
(10 pints-4 pints=) 6 more pints of yellow paint.

ANSWER: You should add 6 pints of yellow to the 4 pints of green in the bucket to make the new color that is 80% yellow.

Write an algebraic expression that is equivalent to the expression cot(arctan x)

Answers

cosX/sinX [tan-¹X]
cos²x/sin²x = cot²x
recall cot²x = cosec²x - 1

The algebraic expression equivalent to cot(arctan x) is 1 / x, derived by recognizing that cot(θ) is the reciprocal of tan(θ), and tan(θ) = x for θ = tan-1(x)

To find an algebraic expression for cot(arctan x), let's follow a step-by-step transformation using trigonometric identities: cot(arctan x) is denoted as cot(tan-1(x))

First, let
θ = tan-1(x). By definition of the arctan function, we have the relation:tan(θ) = x.Next, we need to find cot(θ). Recall that:cot(θ) = 1 / tan(θ).Since tan(θ) = x, we substitute to get:cot(θ) = 1 / x .Thus, we have cot(tan-1(x)) = 1 / x.

Therefore, the algebraic expression equivalent to cot(tan-1(x)) is 1 / x.

An Uber driver carries riders to and from a local airport and a neighboring suburb. Due to traffic and the time of day the driver works, the trip to the airport takes 60 minutes longer than the trip to the suburb. The car’s average speed in traffic is 30 miles per hour. Without traffic, the car travels 15 miles per hour. The equation can be used to determine how many miles apart the two locations are shown. What is the value of m, the distances between the two locations?

A) 0.5 miles
B) 22.5 miles
C) 30 miles
D) 90 miles

Answers

Answer: Choice B) 22.5 miles

--------------------------------------------
--------------------------------------------

To find that answer, we simply solve for m

m/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1) ... multiply both sides by the LCD to clear out fractions
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2 <--- answer as a fraction
m = 22.5 <--- answer in decimal form

Use a calculator or long division to convert from fraction to decimal form.

There are 6,657 marbles in a jar. approximately 34% are white, and the rest are black. how many black marbles are there?

Answers

So if there are 34% white marbles, that means that 66% are black (100% - 34% = 66%). 

If 100% = 1.00, then 66% = 0.66.

Now, you just need to multiply the total by this decimal in order to find the number of black marbles:

6657 x 0.66 = 4393.62, which can be rounded to 4394

Therefore, there are about 4394 black marbles in the jar. 

I hope this helps!

To find the number of black marbles, calculate the percentage of white marbles first and then subtract it from the total marbles, there are 4,394 black marbles in the jar.

To find the number of black marbles:

Calculate the number of white marbles: 34% of 6,657 = 0.34 x 6,657 = 2,263.Subtract the number of white marbles from the total marbles to find the number of black marbles: 6,657 - 2,263 = 4,394.

Therefore, there are 4,394 black marbles in the jar.

A tile factory earns money by a flat fee for delivery and sales price per tile sold. For one customer the tile factory shipped 10,000 units of retail stores at the rate of $0.25 Per tile.

Sold?
A) y=0.25x+10,000
B) y=0.25x+3,000
C) y=0.25x+500
D) y=0.25x+0.25

Answers

10,000 tiles  * 0.25 = 2500

 3000 -2500 = 500

 so the delivery fee is 500 and the tiles cost 0.25 each

 so the equation would be y = 0.25x +500
