Susan has 600 feet of fencing to use in making a yard for her new puppy. The yard she has
planned has a length that is 75 feet less than twice the width. What are the dimensions of the
yard?

Answers

Answer:

Length = 175

Width = 125

Step-by-step explanation:

P=2(L+W)

600ft=2(L+W)

300=L+W

300=2W-75ft+W

375=3W

125=W

L=2W-75

L=2(125)-75

L=250-75

L=175

Answers

Answer:

The point of intersection of the diagonals of a rectangle is 4 cm further away from the smaller side than from the larger side of the rectangle. The perimeter of the rectangle is equal to 56cm. Find the lengths of each side of the rectangle

Answers

Answer:

smaller side: 10 cmlarger side: 18 cm

Step-by-step explanation:

The given relationships can be translated to equations using L and W for the length and width of the rectangle. The distance from the center to the short side is L/2, and the distance from the center to the long side is W/2.

Setup

  P = 2(L +W) . . . . . formula for the perimeter

  56 = 2(L +W) . . . . . the perimeter is 56 cm

  L/2 = 4 + W/2 . . . . . distance to short side is 4 cm longer

__

Solution

Dividing the first equation by 2 gives ...

  28 = L +W

Multiplying the second equation by 2 gives ...

  L = 8 + W

Substituting for L in the first equation, we have ...

  28 = (8 +W) +W . . . . . . use L=8+W

  20 = 2W . . . . . . . . .subtract 8

  10 = W . . . . . . . . divide by 2

  L = 8 +10 = 18 . . . . . find the length

__

The smaller side is 10 cm; the larger side is 18 cm.

Answers

Answer:

7 steps.

Step-by-step explanation:

Since the monkey is sitting on the first step already you can subtract 9 by 1 to find the amount of steps left.

9-1 = 8 steps left

The monkey jumps 3 steps down

8-3= 5 steps

Then jumps 2 steps up

5 + 2 = 7 steps

The monkey has 7 more steps until he reaches the water level.

The total cost of the game Dante wants to buy is 26 dollars.

What is a fraction?

A fraction describes some parts of a certain quantity. Fractions are of two types one is a proper fraction and another is an improper fraction. In a proper fraction, the numerator is smaller than the denominator and n improper fraction numerator is greater than the denominator.

Assuming The total cost of the game is x dollars.

Given that 24 dollars is (2/3)rd of the total cost of the game.

So we can write 24 is (2/3)rd of the total cost of the game.

∴ 24 = (2/3)×x.

24 = (2/3)x.

x = 24×(3/2).

x = 12×3.

x = 36 dollars.

a how much will he have in 4. At the age of 30, Jasmine started a retirement account with $50,000 which compounded interest semi-annually with an APR of 4%. She made no further deposits. After 25 years, she decided to withdraw 50% of what had accumulated in the account so that she could con- tribute towards her grandchild's college education. She had to pay a 10% penalty on the early withdrawal. What was her penalty?​

Answers

Answer:

6795.70

Step-by-step explanation:

smart people

After paying 10% penalty on the early withdrawal, Jasmine's penalty for the early withdrawal was calculated to be $5,352.24.

What is the compound interest?

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

here, we have,

We can use the formula for compound interest in ordr to solve this problem.

A = P(1 + r/n)^(nt)

Where:

A = the final amount

P = the principal (starting amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have the following values,

P = $50,000

r = 1.75% = 0.0175 (since it is compounded semi-annually, n = 2)

t = 25 years

So the final amount after 25 years can be calculated as under

A = 50000(1 + 0.0175/2)^(2×25) = $107,044.84

Jasmine has withdrawn  50% of this amount, which is:

$107,044.84 × 0.5 = $53,522.42

She had to pay a 10% penalty on the early withdrawal, so her penalty would be:

$53,522.42 × 0.1 = $5,352.24

Therefore, the penalty of Jasmine penalty for the early withdrawal was $5,352.24.

Answers

Answer:

θ ≈ 64.62°

Step-by-step explanation:

In this problem we will use trig: SOH CAH TOA. Since we are given hypotenuse (line AB) and adjacent (line ) to the missing angle θ, we will use cosine.

cosθ = adjacent/hypotenuse

cosθ = 3/7

Now take inverse cosine of both sides to cancel out cosine and find the missing angle:

cos⁻¹(cosθ) = cos⁻¹(3/7)

θ = cos⁻¹(3/7)         ---->      Plug into calculator

θ ≈ 1.128 radians · 180°/π rad   ------>.  Convert from radians to degrees

θ ≈ 64.62°

Hope this helps!

Answer: The measure of angle ? is approximately 64.62 degrees.

Step-by-step explanation:

The given value 3 is adjacent to angle ? and 7 is the hypotenuse. Remembering SOH CAH TOA, that means 3/7 = cos(?). To solve, use a calculator to find the inverse cosine of 3/7, which is about 64.62.
