Please help! I am so bad at math!

Answer:

the answer to this problem is H = -12

Answer:

h=-12

Step-by-step explanation:

You have to isolate h. As such, add 1 to both sides in order to get rid of the -1 on the left side. Then, multiply by 6 on both sides in order to get h by itself.

Answer:

{12, 16, 20}

Step-by-step explanation:

12×12+16×16=20×20

pythagorean theorem

Answer:

b) b=a/h

Step-by-step explanation:

A=bh

Dividing both side by h,

or, b=A/h

OR,

A=bh

or, b=A/h

Answer:

b

Answer:

+1.09%

Step-by-step explanation:

Answer:

The length= 16cm

The width= 6cm

The two long sides are 8cm both so 8 + 8 = 16

And the two short sides are 3cm both so 3 + 3 = 6

So your length should be 16cm and your width 6cm

Answer:

0.03

Step-by-step explanation:

3% as a fraction is 3/100. as a decimal it is 0.03. notice when you read the decimal aloud, it is three one-hundredths, which is also the same read aloud in a fraction.

Answer:

A

Step-by-step explanation:

3/100=0.03

:))) Helps?

[tex]\frac{x^2}{3}-\frac{1}{2}=\frac{x}{3}[/tex]

Because there are 3 and 2 as the denominators. Find the lowest number that both 3 and 2 can divide without any quotients, which is 6.

Multiply all whole equation by 6.

[tex]\frac{x^2}{3}(6)-\frac{1}{2}(6)=\frac{x}{3}(6)\\2x^2-3=2x[/tex]

We should get like this. Then move 2x to subtract.

[tex]2x^2-2x-3=0[/tex]

Because the polynomial is a two-degree and a quadratic equation. We solve the value of x by either factoring, using the formula or completing the square.

But I'll use the Quadratic Formula instead as the factoring doesn't seem to work for the Quadratic Equation with square root answers.

[tex]x=\frac{-b±\sqrt{b^2-4ac} }{2a}[/tex]

This is the formula of Quadratic Equation. Ignore the weird letter as it just randomly appears and can't be deleted.

[tex]x=\frac{-(-2)±\sqrt{(-2)^2-4(2)(-3)} }{2(2)} \\x=\frac{2±\sqrt{4+24} }{4} \\x=\frac{2±\sqrt{28} }{4}\\x=\frac{2±2\sqrt{7} }{4} \\x=\frac{1±\sqrt{7} }{2}[/tex]

Therefore, the answer is x = (1±√7)/2

I have the same test

Answer:

B) j(j^3-5j^2+10)

Step-by-step explanation:

Given: [tex]j^4-5j^3+10j[/tex]

Factor out j: [tex]j(j^3-5j^2+10)[/tex]

We cannot factor out anymore, so the final answer is B) j(j^3-5j^2+10)

I need an answer to the second question

Answer:

The elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.

Step-by-step explanation:

Let's assume the elevation above the sea level is on a number line, then we have to arrange the given number from lowest to highest. These are the numbers in ascending order.

–42ft, –20ft, –18ft, –8ft.

From here we see that, the elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.

Answer:

x=0

Step-by-step explanation:

use math-way it helps

Answer:

Angle of elevation = 80°

Step-by-step explanation:

A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive?

To solve for angle of elevation, we use the Trigonometric function of Tangent.

tan θ = Opposite side/Adjacent side

Opposite side = Height of the tower = 217 ft

Adjacent side = 38ft

tan θ = 217/38

tan θ = 5.6315789474

θ = arc tan 5.6315789474

= 79.930937301°

Approximately = 80°

Answer:

you need to add number lines, but if you want the equation to be written and solved, then...

Step-by-step explanation:

5x - 25 > -15

     +25    +25

5x > 10

divide both sides by 5

x > 2

Hope this helps!!!

Answer:

I think it may be C? I used desmos to graph it but I'm not 100%

Answer:

f(3) = 7

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x), that is

f(3) = 2(3) + 1 = 6 + 1 = 7

Answer:

C the answer is C but I have to write other things to be able to submit this

Step-by-step explanation:

the answer would be C

Answer:

C

Step-by-step explanation:

The sum is the answer to a addition proble. Since it asks for the sum of 6 and one fifth you would use 6 + 1.5x to find the answer. Hope this helps you
