The triangle-shaped entrance to the cavern is 2 1/2 feet tall and 4 feet wide. What is the area of the entrance?

Answers

Answer 1

Answer:

5 feet²

Step-by-step explanation:

The area of entrance = area of triangle

Height, h = 2 1/2 feets

Width, w = 4 feets

The Area of a triangle is given as :

1/2 * base * height

Base = width = 4 feets

Area of entrance = 0.5 * 4 * 2.5

Area of entrance = 5 feet²

Hence, the area of the entrance is 5 feet square.

ANSWER:
d. x = 15, y= 15√3

EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have

We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15

We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.

x = 15
y = 15√3

Answers

Answer:

x = -5

y = -1

Step-by-step explanation:

Y= -6/5x-7 and y=2/5x+1

then:

-6/5x - 7 = 2/5x + 1

simplify:

-8/5x = 8

divide both sides by 8:

-1/5x = 1

multiply both sides by 5:

-x = 5

x = -5

y = 2/5(-5) + 1 = -2 + 1 = -1

5-divide 180 kd between ahmed ,jasim and Dalal in the ratio of 3:1:5.


answer any one of this questions​

Answers

Answer:

1) Lower bound = 23.5 cm

Upper bound = 24.5 cm

2) I disagree

3) 7.88

4) 2.32

5) Ahmed = 60 kg

Jasim = 20 kg

Dalal = 100 kg

Step-by-step explanation:

1) diameter = 24 cm was rounded up to the nearest cm.

Now, usually, we round up 0.5 to the next whole number. This means that, the actual diameter is;

23.5 ≤ D < 24.5

Thus;

Lower bound = 23.5 cm

Upper bound = 24.5 cm

2) If you weigh 57g,converting to kg is 0.57 kg.

Now, this does not fall in between 56.5kg and 57.5kg given.

Thus, I disagree that your weight could be anything between 56.5kg and 57.5kg .

3) 7.875 approximated to the nearest two decimal place = 7.88

4) 2.3242900000 to the nearest 2 decimal place = 2.32

5) 180 kd shared between ahmed ,jasim and Dalal in the ratio of 3:1:5.

Total part of ratio = 3 + 1 + 5 = 9

Their respective shares are;

Ahmed = 3/9 × 180 = 60 kg

Jasim = 1/9 × 180 = 20 kg

Dalal = 5/9 × 180 = 100 kg

You make an initial investment of $500. Fill in the table below to show how much money you would have after 3 years if your account earns compound interest that is compounded annually at a rate of 5%.

Answers

After three years, your investment would be $575. The formula is A=P(1+(r/n)^(n*t) where A is the final amount, P is the initial balance, r is the interest rate, n is the amount of time the interest is compounded in a year, and t is the amount of time that has passed.
P=500
r= 5% is which converted into a decimal by dividing 5 by 100 which is then 0.05
n= 1 since it is compounded annually
t= 3

What is a downside of receiving a tax refund?

Answers

Tax returns aren't gifts. They're refunds you get because the IRS withdrew too much from your paychecks or had withdrawals from other investment accounts. While it may seem like a great thing to have a tax return come each April, you pay for it the other 11 months of the year.

“A refund means you're giving your cash flow and income to the government in an interest-free loan.” The interest rate on one-year U.S. bonds is around 1.5%, so any interest the government could hypothetically pay on that loan would be very small: about $15 for every $1,000 in your refund.

Answers

Answer:

Step-by-step explanation:

Angle 1 is equal to angle 3 because they are opposite each other so

Angle 1=43 degrees

Angle 1 and angle 2 have a sum of 180 degrees because they are adjacent to each other.

angle 2=180-43=137 degrees.

angle 2 and 4 are opposite each other so they are equal

angle 4=137 degrees.

Answer:

Angle 1 = 43°

Angle 2 = 137°

Angls 4 = 137°

Step-by-step explanation:

To get angle 1, l and m intersect and there are two angles which cause vertical opposite angles. When there are vertical opposite angles, both angles have the same degree. For angle 2, you need to find angle 1 and 3, after that you deduct both angle 1 and 3 from 360° which is the angle of whole figure. 360 - 43 - 43 = 274° for angle 2 and 4, since they're also vertically opposite angles, both 2 and 4 have the same angle. All you need to do to find 2 and 4 is 274 ÷ 2 = 137°.

∠WZX = 57°

Step-by-step explanation:

Because it is a rectangle, ∠XYZ is 90°

∠XZY + ∠YXZ = 90

(5x - 8) + (x + 20) = 90

simplify:

6x + 12 = 90

subtract 12 from each side

6x = 78

divide both sides by 6

x = 13

∠WZX is complimentary to angle (x + 20)

∠WZX = 90 - (13 + 20) = 57°

Austin borrowed money from a credit union for 4 years and was charged simple interest at an annual rate of 5% the total interest that he paid was $160 how much money did he borrow​

Answers

Given:

Rate of simple interest = 5%

Time = 4 years

Total interest = $160

To find:

The amount borrowed by Austin from a credit union.

Solution:

The formula for simple interest is:

[tex]I=\dfrac{P\times r\times t}{100}[/tex]

Where, P is principal, r is the rate of interest and t is the number of years.

Putting [tex]I=160,r=5,t=4[/tex] in the above formula, we get

[tex]160=\dfrac{P\times 5\times 4}{100}[/tex]

[tex]160=\dfrac{20P}{100}[/tex]

[tex]160=\dfrac{P}{5}[/tex]

Multiply both sides by 5.

[tex]800=P[/tex]

Therefore, Austin borrowed $800 from a credit union for 4 years.
