3/7=h/14-2/7 solve for h

Mathematics

Snowcat [4.5K]3 years ago

Answer: h = 10

Step-by-step explanation:

\frac{3}{7}=\frac{h}{14}-\frac{2}{7}

Add \frac{2}{7} on both sides to isolate \frac{h}{14} .

\frac{2}{7}+ \frac{3}{7}=\frac{h}{14}-\frac{2}{7}+\frac{2}{7}

\frac{2+3}{7}=\frac{h}{14}

\frac{5}{7}=\frac{h}{14}

Multiply by 14 on both sides.

14*\frac{5}{7}=\frac{h}{14}*14

14 and 7 can be simplified.

14/7=2

7/7=1

2*5=h

10=h

3/7 + 2/7 = 5/7
5/7 = h/14
5/7 x 2 = 10/14
10/14 = h/14
h = 10

The area of a triangle is 1,4440 cm^2. The base of the triangle is 5 times the height. What is the height of the triangle?
DochEvi [55]

Answer:

h = 24 cm

Step-by-step explanation:

The formula for area of a triangle is

A = (1/2)bh     where b is the base and h is the height.

We are told that the base is 5 times the height, this translates to

b = 5h, so we can rewrite our formula to

A = (1/2)(5h)(h)  or

A = (1/2)5h²

We are given A = 1,440, so plug that in and solve for h...

1,440 = (1/2)5h²

    2,880 = 5h²    (multiply both sides by 2 to get rid of the fraction)

      576 = h²    (divide both sides by 5 to get the h value by itself)

         24 = h     (take the square root of both sides)

Factorise the following using the Difference of Two Squares or Perfect Squares rule: a) (2x-2)^2 - (x+4)^2 b) (3x+4) (3x-4)
emmainna [20.7K]

Answer:

Step-by-step explanation:

Hello, please consider the following.

a)

(2x-2)^2 - (x+4)^2 \\\\=(2x-2-(x+4))(2x-2+x+4)\\\\=(2x-2-x-4)(3x+2)\\\\=\boxed{(x-6)(3x+2)}

b)

(3x+4) (3x-4)\\\\=(3x)^2-4^2\\\\=\boxed{9x^2-16}

Thank you.

An aquarium tank can hold 7200 liters of water. there are two pipes that can be used to fill the tank. the first pipe alone can
Arada [10]

The first pipe pumps out

\dfrac{7200\text{ L}}{48\text{ min}}=\dfrac{150\text{ L}}{1\text{ min}}

while the second pipe pumps out

\dfrac{7200\text{ L}}{96\text{ min}}=\dfrac{75\text{ L}}{1\text{ min}}

So together, both pipes pump out

\dfrac{150+75\text{ L}}{1\text{ min}}=\dfrac{225\text{ L}}{1\text{ min}}=\dfrac{7200\text{ L}}{32\text{ min}}

That is, with both pipes filling the tank, it should take 32 minutes total.
