Trucks must haul between 150,000 yd' and 180,000 yd of earth each day to create a new

water park near Universal Studios in Orlando, Florida. The trucks can haul 10.000 yd per day

and 120,500 yds have already been brought to the site. How many days are needed to

complete this job?

Answers

Answer 1

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Range which must be hauled by trucks :

150,000 - 180,000 yds of earth

Haul per day = 10000 yds

Already removed = 120,500

We can express the problem as an inequality:

Using y = number of days

150,000 ≤ (10000y + 120,500) ≤ 180000

150,000 ≤ (10000y + 120,500)

150000 - 120500 ≤ 10000y

29500/10000

y = 2.95 days

10000y + 120,500 ≤ 160000

10000y ≤ 160000 - 120500

y = 39500/10000

y = 3.95

2.95 ≤ y ≤ 3.95

52-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is two inches more than seven times the length of the first piece. Find the lengths of the pieces. The lengths of the first, the second, and the third pieces are in, in, and in respectively.

Answers

Answer:

First piece = a = 5 inches

Second piece = b = 10 inches

Third piece = c = 37 inches

Step-by-step explanation:

Let us represent:

First piece = a

Second piece = b

Third piece = c

52-inch piece of steel is cut into three pieces.

a + b + c = 52 inches

The second piece is twice as long as the first piece

= b = 2a

The third piece is two inches more than seven times the length of the first piece.

= c = 2 + 7(a)

Find the lengths of the pieces. The lengths of the first, the second, and the third pieces are in, in, and in respectively.

a + b + c = 52 inches

Substitute 2a for b

2 + 7a for c

a + 2a + 2 + 7a = 52

Collect like terms

10a = 52 - 2

10a = 50

a = 50/10

a = 5 inches.

b = 2a

b = (2 × 5)

b = 10 inches

c = 2 + 7a

= 2 + 7(5)

= 2 + 35

= 37 inches

The distance between the Sun and each planet in our solar system varies because the planets travel in elliptical (oval) orbits around the Sun rather than completely circular ones.

Here is a table of the average distance and the variation in the distance for the five innermost planets in our solar system:

Average Distance and Variation
Planet Name Average Distance Variation
Mercury 36.0 million miles 7.39 million miles
Venus 67.2 million miles 0.43 million miles
Earth 93.0 million miles 1.55 million miles
Mars 142 million miles 13.2 million miles
Jupiter 484 million miles 23.2 million miles


"Average distance" means the mean distance that planet is from the sun over the course of its orbit, and "variation" means how far it varies from that mean. For example, if a planet had an average distance of 5 miles and a variation of one mile, it would have distances between 4 and 6 miles at different times.

a) Write and solve an inequality to represent the range of distances that can occur between the Sun and one of the planets from the table (your choice). Show your steps/process.

b) Why is this best represented as an inequality rather than an equation? Explain in at least 3 sentences.

Answers

Answer:

Hope this helps

Step-by-step explanation:

They describe how (1) planets move in elliptical orbits with the Sun as a focus, (2) a planet covers the same area of space in the same amount of time no matter where it is in its orbit, and (3) a planet's orbital period is proportional to the size of its orbit (its semi-major axis)

Consider the equation −3+(−9.25)+m=0 .

Answers

Let's solve your equation step-by-step.

−3−9.25+m=0

Step 1: Simplify both sides of the equation.

−3−9.25+m=0

−3+−9.25+m=0

(m)+(−3+−9.25)=0(Combine Like Terms)

m+−12.25=0

m−12.25=0

Step 2: Add 12.25 to both sides.

m−12.25+12.25=0+12.25

m=12.25

Answer:

Step-by-step explanation:

This is my first time posting, so sorry if this isn't that clear.

Anyways:

We want to find the x-intercept, and the y-intercept. The x-intercept will always have 0 as y, and the y-intercept will always have 0 as x.

We can find the x-intercept by plugging in 0 as y. So:

x/4+0/12=1

x/4=1

x=4

a=4 (since a is equal to the x-intercept.)

We can find the y intercept by plugging in x as 0:

0/4+y/12=1

y/12=1

y=12

b=12

We can find the slope by using the equation y2-y1/x2-x1, but theres an easier way. Simplifying the original equation x/4+y/12=1 into y=--3x+12 immediatly gets us the slope of -3.

So, 12+4-3=13.

(In case you didn't know how I got y=-3x+12. This is how:

x/4+y/12=1

12(x/4+y/12)=1(12)

3x+y=12

y=-3x+12 )

A math test had 26 questions. The questions were either true/false or multiple choice. The true/false questions were worth 2 points each and the multiple choice were worth 5 points each. If the test is worth 100 points, how many of each type of question are included on the test?

Answers

Answer:

True/ false type 10 questions

Multiple choice type 16 questions  

Step-by-step explanation:

Using the given formation we can make equations to solve for the number of questions of either type is to be included

let the no of true/false be =x

let the number of multiple choice to be included be = y

x + y=26  .............(1)

now making the equation of points

2x + 5y = 100 .........(2)

substitute y = 26-x from first equation in the second equation

2x + 5(26 - x ) = 100

2x - 5x + 130 = 100

3x=30

x=10

y =26-10=16
