At the school carnival, students are asked to guess the number of marbles in a jar to win a prize. There are 240 marbles in the

Lapatulllka [165]

There is 17% error in the guess.

Step-by-step explanation:

Given,

Number of marbles in jar = Exact value = 240

Closest guess = Approx Value = 280

Percent error = $\frac{|approx-exact}{exact}*100$

Percent error = $\frac{|280-240|}{240}*100\\$

Percent error = $\frac{|40|}{240}*100$

Percent error = $\frac{4000}{240}=16.67\%$

Rounding off to nearest whole percent

Percent error = 17%

There is 17% error in the guess.

How do you solve for a side in a right triangle that has a hypotenuse of 10, an angle of 35, and the side across from the angle

goblinko [34]

$\sin \theta = \dfrac{\textrm{opposite}}{\textrm{hypotenuse}}$

$\sin 35^\circ = \dfrac{x}{10}$

$x = 10 \sin 35^\circ$

That's the exact answer; they usually want a calculator approximation at this point,

$x \approx 5.735$

What is the simplified form of the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?

grigory [225]

Answer:

n = 2

Step-by-step explanation:

Here, we want to write the simplified form of the equation given in the question.

Firstly, we write the equation in an equation form:

4/5n -1/5 = 2/5n

5n(4/5n -1/5) = 2/5n(5n)

(4/5n * 5n) -(1/5)(5n) = 2

4- n = 2

n =4-2

n = 2
