Bills family is driving across the country on vacation . They plan to stop at historical sites in each state they drive through. The total mileage of the trip is 3,000 miles. They have driven 900 miles so far what percent of driving do they still have left?
Answer: Blll's family has 70% of driving left.
Step-by-step explanation:
The total mileage of the trip = 3,000 miles.
miles driven so far = 900miles
Miles of diatance left = 3000- 900=2100
Percentage of driving left = Miles of diatance left / Total miles to cover x 100
=2100/3000 x 100
= 7/10 x100
70%

A square has side length represented by X +4 inches write an expression to represent the area. Express your answer as a trinomial.
Answer:
[tex]A=(x^2+16+8x)\ \text{inches}^2[/tex]
Step-by-step explanation:
Given that,
The side length of a square, l = (x+4) inches
We need to find an expression to represent the area of the square.
The area of a square is given by :
[tex]A=\text{side}^2[/tex]
So,
[tex]A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2[/tex]
So, the area of the square is [tex](x^2+16+8x)\ \text{inches}^2[/tex].

cubic feet= 1 cubic yard
Answer:
(1 yard) 3 = 1 3 yard*yard*yard = 1 yard*yard*yard = 1 cubic yard. Since 1 yard = 3 feet, we have.
1 cubic yard = (1 yard) 3 = (3 feet) 3 = 33 feet*feet*feet = 27 cubic feet.

One of the roots of the quadratic equation dx^2+cx+p=0 is twice the other, find the relationship between d, c and p
Answer:
[tex]c^2 = 9dp[/tex]
Step-by-step explanation:
Given
[tex]dx^2 + cx + p = 0[/tex]
Let the roots be [tex]\alpha[/tex] and [tex]\beta[/tex]
So:
[tex]\alpha = 2\beta[/tex]
Required
Determine the relationship between d, c and p
[tex]dx^2 + cx + p = 0[/tex]
Divide through by d
[tex]\frac{dx^2}{d} + \frac{cx}{d} + \frac{p}{d} = 0[/tex]
[tex]x^2 + \frac{c}{d}x + \frac{p}{d} = 0[/tex]
A quadratic equation has the form:
[tex]x^2 - (\alpha + \beta)x + \alpha \beta = 0[/tex]
So:
[tex]x^2 - (2\beta+ \beta)x + \beta*\beta = 0[/tex]
[tex]x^2 - (3\beta)x + \beta^2 = 0[/tex]
So, we have:
[tex]\frac{c}{d} = -3\beta[/tex] -- (1)
and
[tex]\frac{p}{d} = \beta^2[/tex] -- (2)
Make [tex]\beta[/tex] the subject in (1)
[tex]\frac{c}{d} = -3\beta[/tex]
[tex]\beta = -\frac{c}{3d}[/tex]
Substitute [tex]\beta = -\frac{c}{3d}[/tex] in (2)
[tex]\frac{p}{d} = (-\frac{c}{3d})^2[/tex]
[tex]\frac{p}{d} = \frac{c^2}{9d^2}[/tex]
Multiply both sides by d
[tex]d * \frac{p}{d} = \frac{c^2}{9d^2}*d[/tex]
[tex]p = \frac{c^2}{9d}[/tex]
Cross Multiply
[tex]9dp = c^2[/tex]
or
[tex]c^2 = 9dp[/tex]
Hence, the relationship between d, c and p is: [tex]c^2 = 9dp[/tex]

14m squared
Step-by-step explanation:
2.5×2=5
5÷2=2.5
2.5 is the area for each triangle and there are four triangles altogether so

to find the square do 2×2=4
so 4m+10m=14m
You are selling concessions at a local swim meet. Hot dogs are being sold for
$1.00 and soda is being sold for $0.50. At the end of the day you made $150.
Let x represent the number of hotdogs sold and y represent the number of
sodas sold. Write an equation that can be used to find the number of hotdogs
and sodas sold at the swim meet.
Answer:
150 = 0.50y + 1.00x

2.A filled provides grazing for sheep for 8 days. How many days grazing would it provide for 24 sheep
Given:
Consider the complete question is "A field provides grazing for 18 sheep for 8 days. How many days grazing would it provide for 24 sheep?".
To find:
The number of days the field provides grazing for 24 sheep.
Solution:
We have,
If number of sheep = 18, then, number of days = 8.
If number of sheep = 24, then, number of days = x.
Now, the products of number of sheep and number of days are equal because they represent the total work done.
[tex]18\times 8=24\times x[/tex]
[tex]\dfrac{18\times 8}{24}=x[/tex]
[tex]\dfrac{144}{24}=x[/tex]
[tex]6=x[/tex]
Therefore, the field provides grazing for 24 sheep for 6 days.
There were 54 runners to start a race. In the first half of the race, 1/3 of them dropped out. In the second half of the race, 5/6 of the remaining runners dropped out. How many runners finished the race?
Answer:
6 runners finished the race
Step-by-step explanation:
Total number of runners = 54
In the first half of the race, 1/3 of them dropped out
= 1/3 of 54
= 1/3 * 54
= 54/3
= 18 runners
Runners remaining after first half = total runners - dropped out runners at first half
= 54 - 18
= 36 runners
In the second half of the race, 5/6 of the remaining runners dropped out
= 5/6 * 36
= (5*36)/6
= 180/6
= 30 runners
Runners remaining after second half = runners remaining after first half - dropped out runners at second half
=36 - 30
= 6 runners
Therefore, 6 runners finished the race
A project manager has ordered 252 pallets of concrete blocks for a construction project. Casone's trucks can each carry 14 pallets of blocks at a time. The project manager used partial quotients to find the number of delivery trucks to expect. His work is shown at the right. Is his solution correct? Explain
Answer:
18 trucks of delivery
Step-by-step explanation:
Total pallets of concrete blocks ordered = 252 pallets
If each truck can carry 14pallets, then;
1 truck = 14pallets
To determine the number of delivery truck 252pallets can carry, we can express this as:
x truck = 252pallets
Divide both expressions
1/x = 14/252
Cross multiply
14x = 1×252
14x = 252
x = 252/14
x = 18
Hence the manger should expect 1 18 trucks of delivery
