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
Answer:
smaller side: 10 cmlarger side: 18 cmStep-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.
SetupP = 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
__
SolutionDividing 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

A copy machine prints 10 copies per minute.
At what rate, in copies per minute, does the copy machine print?
Enter your answer in the space provided.
The rate in copies per minute the copy machine print is 10 copies per minutes.
What is rate?Rate is the ratio between two related quantities in different units.
In other word rate is a quotient of two measurements with different units.
In our case we were asked to find the rate at which the machine prints per minutes.
The two related quantities are amount printed and the time in minutes.
Since, the copy machine prints 10 copies in one minutes, the rate at which the copy machine print per minute is 10 copies per minutes.

how do i do this? im confused
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.

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?
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.

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.

Using the trigonometric ratios, the value of cos F in the right angle triangle is 0.28 .
What are right angle triangle?Right angle triangle are triangle that has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore,
cos F = adjacent / hypotenuse
