A parallelogram has a height of x cm. The length of its base is 4 cm greater than its height. A triangle has the same height as
LuckyWell [14K]

The value of x when the triangle and the parallelogram have the same area is 6 units

<h3>The dimensions</h3>

The dimension of the parallelogram is given as:

  • Height = x
  • Base = 4 + x

The dimension of the triangle is given as:

  • Height = x
  • Base = 20

<h3>Areas</h3>

The area of a shape is the amount of space it occupies

The area of the parallelogram is calculated as:

Area = x (4 + x)

The area of the triangle is calculated as:

Area = 0.5 \times 20 \times x

Area = 10x

Both areas are equal.

So, we have:

x(4 + x) = 10x

Divide both sides by x

4 + x = 10

Subtract 4 from both sides

x =6

Hence, the value of x is 6 units

PLS HELP
Lemur [1.5K]

Answer:

21 feet

Explanation:

Using pythagorean theorem to find the length of the added length of the bottom.

A^2+B^2=C^2 or 4^2+B^2=5^2 or 16+B^2=25

25-16=9 so B^2 is 9 and the square root of that is 3 so B is 3. Then you add 15+3+3 to get 21.

An electrician has 4.1 meters of wire how many strips 7/10 meter can he cut
spin [16.1K]
Turn 7/10 into decimal. (0.7)

Keep adding by 0.7 until you get the number closest to 4.1

3.5 is the closest, if we add another 0.7, we get 4.2.

So, he can get 5 sections of 0.7m

Patricia scored 80% on her math test. She missed 4 problems. How many problems were on the test?
Yuri [45]

Hey there!

If she missed 4 problems, and that took off 20%, that means 4 is 20% of the total items.

20% is the same as 1/5 of the total amount, since there are 5 20s in 100.  

So, we can simply multiply 4 by 5 to get the total amount of problems.

4 x 5 = 20

This means there were 20 problems on the test.

Hope this helps!
