Enter the value of the answer in the first blank and enter the units in the second.


Enter your answer in decimal form. Round to the nearest tenth if rounding is necessary.


Enter units as ft., square ft., or cubic ft.

Answers

Answer:

The area of each section of the kennel is 33 square ft

Step-by-step explanation:

The given parameters for the fencing are;

The length of each section, L = 2 ft + The width, 3×W

The total amount of fencing = 113 feet

The The total perimeter of the kennel = 12·W + 7·L = 113

Were we are given L = 2 + 3·W

By substitution, we have;

12 × W + 7 × (2 + 3·W) = 113

33·W + 14 = 113

33·W  = 113 - 14 = 99

W = 99/33 = 3

W = 3 ft.

L = 2 + 3·W = 2 + 3 × 3 = 11

L = 11 ft.

The area of each section of the kennel, A = L × W = 3 × 11 = 33 square ft.

The area of each section of the kennel = 33 square ft.

To begin a basketball game, a referee msut toss the ball vertically into the air. This process can be modeled by the equation h(t) = -16t^2+22t+6, where h represents the ball's height (in feet) after t seconds. Determine the time interval (in seconds) in which the height of the basketball is 8 feet. Round your answer to the nearest thousandth of a second

Answers

Answer:

1.277s and 0.098s

Step-by-step explanation:

Given the height of the ball modelled by the equation

h(t) = -16t^2+22t+6, where;

t is the time in seconds

To calculate the time interval (in seconds) in which the height of the basketball is 8 feet, we will simply substitute h(t) = 8 into the expression and calculate t as shown;

8 = -16t^2+22t+6

Divide through by 2

4 = -8t^2+11t+3

-8t^2+11t+3-4 = 0

8t^2-11t+1 = 0

t = 11±√11²-4(8)/2(8)

t = 11±√121-32/16

t = 11±√89/16

t = 11±9.43/16

t = 11+9.43/16 and t = 11-9.43/16

t = 20.43/16 and t = 1.57/16

t = 1.277s and t = 0.098s

Hence the time interval to the nearest thousands are 1.277s and 0.098s

Write the equation of the line that goes through the point (2, -1) and has a slope of
-3.

Answers

Answer:

y=-3 -1

Step-by-step explanation:

y=mx+b m=slope b= y intercept

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = - 3x + 5 ← equation of line

Solve for y.
ln(2y−1)=3

Answer y=(e^3+1/2)

for future reference

Answers

Answer:

The correct answer should be:

[tex]y=\frac{1}{2}(e^3+1)\text{ or } y=\frac{e^3}{2}+\frac{1}{2}[/tex]

Step-by-step explanation:

We have the equation:

[tex]\ln(2y-1)=3[/tex]

Let’s remove the natural logarithm by raising both sides to e. This yields:

[tex]e^{\ln(2y-1)}=e^3[/tex]

The left will simplify to:

[tex]2y-1=e^3[/tex]

Add 1 to both sides:

[tex]2y=e^3+1[/tex]

Divide both sides by 2. So, the value of y should be:

[tex]y=\frac{1}{2}(e^3+1)[/tex]

A racehorse breeder's sells feed by the ton (2000 pounds). They add a special supplement to the feed. Each horse needs 300 milligrams (mg) of this supplement a day and each horse consumes 15 pounds of the feed per day. If there are 1,000 milligrams in a gram, how many grams of the medication should the feed company add for each ton of feed they produce

Answers

Answer: 40 grams

Step-by-step explanation:

Each horse needs 300 milligrams and each horse eats 15 pounds of feed per day.

This means that 300 milligrams should be in 15 pounds of feed.

In 2,000 pounds therefore, the medication that should be added is;

= (2,000 * 300) / 15

= 40,000 milligrams of supplement

Question calls for how much grams are needed.

1 gram is 1,000mg

40,000 milligrams is;

= 40,000/1,000

= 40 grams

(-4,1) and (-8,7)

write an equation in slope-intercept form

Answers

Answer:

y = -2x - 9

Step-by-step explanation:

so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.

-1 = -2(-4) + b

multiply -2 and -4

-1 = 8 + b

we subtract 8 from itself and -1

-9 = b

Our equation is y = -2x - 9

Answers

Answer:

The length of PQ is 18 feet.

The length of PR is 18 feet.

The length of QR is 24 feet.

Step-by-step explanation:

A way to set an equation up for this problem is:

[tex]\frac{4}{3}x+x+x=60[/tex]

where x is the three lengths of the isosceles triangle, but the base QR is 4/3 the length of the other two congruent sides, length PQ and PR. The 60 represents the total length of the perimeter.

Then, solve for x from the equation, and you’ll get x=18. But your not done yet. Since the variable x in the equation stands for the sides of the isosceles triangle, so plug 18 into the equation and it should look like this:

[tex]\frac{4}{3}(18)+18+18=60[/tex]

Don’t solve the whole equation, just solve the [tex]\frac{4}{3}(18)[/tex] part of the equation, which is equal to 24. So the final equation is this:

[tex]24+18+18=60[/tex]

Conclusion: 24 is the length of QR, and 18 is the length of PQ and PR. And they all equal 60, which is the perimeter. This is very true because the length of PQ and PR are the same (length 18), since it’s an isosceles triangle, and the length of QR is 4/3 the length of PQ and PR (4/3 of 18= 24).

Step-by-step explanation:

Every triangle has a measure of 180, so if we know two of the angles we can find the last one easily. To find angle 1, we first must find angle 2. 2 must be equal to 42 because it is vertical to the other angle that is equal to 42 degrees. Then to find angle 1 do the operation 180-(50+42). This equals 88, which is the measure of angle 1.

Eli and his children went into a movie theater and will buy candies and pretzels. Each candy costs $3.50 and each pretzel costs $3.25. Eli has a total of $30 to spend on candies and pretzels. Write an inequality that would represent the possible values for the number of candies purchased, cc, and the number of pretzels purchased, p.p.

Answers

Answer: He spent $7.25 dollars.

Step-by-step explanation:

$3.50 + 3.25 = 7.25

Inequality shows a relationship between two numbers or two expressions.

The inequality that would represent the possible values for the number of candies purchased c and the number of pretzels purchased p is

3.50c + 3.25p ≤ 30

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

Cost of candy = $3.50

Cost of a pretzel = $3.25

Total amount to spend = $30

Let the number of candies = c

Let the number of pretzels = p

The inequality to spend on possible numbers of candies and pretzels:

3.50c + 3.25p ≤ 30

Thus,

The inequality that would represent the possible values for the number of candies purchased c and the number of pretzels purchased p is

3.50c + 3.25p ≤ 30

He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.He looked hopelessly across the dark spaceport. It was a large one, for this ancient town of Syrtis was the main port of Mars. The forked light of the flying moons showed many ships docked on the tarmaca big liner, several freighters, a small, shining cruiser and other small craft. And for lack of one of those ships, his hopes were ruined!A squat, brawny figure in shapeless space-jacket came to Kenniston's side. It was Holk Or, the Jovian who had been waiting for him."What luck?" asked the Jovian in a rumbling whisper."It's hopeless," Kenniston answered heavily. "There isn't a small cruiser to be had at any price. The meteor-miners buy up all small ships here.""The devil!" muttered Holk Or, dismayed. "What are we going to do? Go on to Earth and get a cruiser there?""We can't do that," Kenniston answered. "You know we've got to get back to that asteroid within two weeks. We've got to get a ship here."Desperation made Kenniston's voice taut. His lean, hard face was bleak with knowledge of disastrous failure.The big Jovian scratched his head. In the shifting moonlight his battered green face expressed ignorant perplexity as he stared across the busy spaceport."That shiny little cruiser there would be just the thing," Holk Or muttered, looking at the gleaming, torpedo-shaped craft nearby. "It would hold all the stuff we've got to take; and with robot controls we two could run it.""We haven't a chance to get that craft," Kenniston told him. "I found out that it's under charter to a bunch of rich Earth youngsters who came out here in it for a pleasure cruise. A girl named Loring, heiress to Loring Radium, is the head of the party."The Jovian swore. "Just the ship we need, and a lot of spoiled kids are using it for thrill-hunting!"Kenniston had an idea. "It might be," he said slowly, "that they're tired of the cruise by this time and would sell us the craft.
