Solve for b. 16 = a² + b^2

laiz [17]

Answer:

$\sqrt{(4-a)(4+a)} =b$

Step-by-step explanation:

16 = a^2 + b^2

16 - a^2 =b^2

4^2 - a^2 = b^2

$\sqrt{4^2 - a^2} =b$

$\sqrt{(4-a)(4+a)} =b$

Please I need help, if you could show work too that would be amazing

Answer:

x = 3

Step-by-step explanation:

Hi there,

We know that the value of ∠ABD and ∠DBC are the same because BD bisects it. Therefore, we can set both of the angle values equal to each other to find the value of x.

9x = (8x + 3)

x = 3

Hope this answer helps. Feel free to ask questions. Cheers.

One integer is 8 times another. if the product of the two integers is 288, then find the integers.

Anarel [89]

One integer is x
another integer is y

x=8y
xy=288

(8y)(y)=288
8y^2=288
Divide both sides by 8
y^2= 36
The square root of 36 is 6
y=6

x=8y = 8(6) = 48
x=48

Hope someone can help me with this

Hi,

To find the volume of cylinder this formula is required.

$v = \pi {r}^{2} h$

To get radius you need to divide diameter with 2 like this.

$80 \div 2 = 40$

Now just put your values into formula.

$v = \pi {40}^{2} \times 130 \\ v =653451.27$

You will need 653451.27 cubic centimetres of concrete.

Hope this helps.
