What is the grade if there are 85 questions and u miss 9

If you miss 9 questions, the how many did you get right?

85 - 9 = 76

So now you got 76 out of 85 correct or 76/85...

Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...

76 divided by 85 which equals...

.8941

Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)

.8941 x 100 = 89.41% Round to nearest one percent...

89%

Given \qquad m \angle LONm∠LONm, angle, L, O, N is a straight angle. \qquad m \angle MON = 8x - 13^\circm∠MON=8x−13 ∘ m, angle,

Tamiku [17]

Answer:

<h3> $\boxed{99°}$ </h3><h3 />

Step-by-step explanation:

m<MON = 8x - 13°

m<LOM = 7x - 17°

To find : m <MON

First, we have to find the value of x :

Create an equation

$\mathrm{8x - 13 + 7x - 17 = 180}$ ( sum of angle in straight line )

Collect like terms

$\mathrm{15x - 13 - 17 = 180}$

Calculate

$\mathrm{15x - 30 = 180}$

Move constant to R.H.S and change its sign

$\mathrm{15x = 180 + 30}$

Calculate the sum

$\mathrm{15x = 210}$

Divide both sides of the equation by 15

$\mathrm{ \frac{15x}{15} = \frac{210}{15} }$

Calculate

$\mathrm{x = 14}$

Now, let's find the value of m<MON

$\mathrm{8x - 13}$

Plug the value of x

$\mathrm{ = 8 \times 14 - 13}$

Calculate the product

$\mathrm{ = 112 - 13}$

Calculate the difference

$\mathrm{ = 99}$ °

Hope I helped!

Best regards!

Determine if the function f(x) = 4√x − 3x satisfies the Mean Value Theorem on [4, 49]. If so, find all numbers c on the interval

Vedmedyk [2.9K]

Answer:

c

Step-by-step explanation:

The mean value theorem states that for a continuous and differentiable function on a interval there exists a number c from that interval, that

$f'(c)=(f(b)-f(a))/(b-a)$

First we must determine the endpoints:

$f(49)=-119$

$f(4)=-4$

We find the derivative of the function, f'(c)

$f'(c)=3+2\sqrt{c}$

Therefore:

$3+2\sqrt{c}=((-119)-(-4))/((49)-(4))$

Simplify:

$3+2\sqrt{c}=-23/9$

$c=81/4$
