In sugar beet, there is 21% of sugar. How much sugar beet do you need in order to get 7,413 tons of sugar?

35300 tons of sugar beet we need in order to get 7,413 tons of sugar.

<u>Step-by-step explanation:</u>

Given that in sugar beet, there is 21% of sugar. Need to find out how much sugar beet we need in order to get 7,413 tons of sugar. Let we need x tone of sugar beet. So, according to the asked data, we have

$21 \% \text { of } x=7413$

$\frac{21}{100} \times x=7413$

$0.21 \times x=7413$

$x=\frac{7413}{0.21}$

x = 35300 tones

Tan ^-1 (-1). enter your answer in radians

Assoli18 [71]

Answer:

$\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}$

Step-by-step explanation:

we are given

$tan^{-1}(-1)$

Let's assume angle as theta

$\theta =tan^{-1}(-1)$

so, we get

$tan(\theta)=-1$

now, we can use unit circle and find theta

and we get

$\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}$

So, solution is

$\theta=\frac{3\pi}{4},\theta=\frac{7\pi}{4}$

Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x

andrew-mc [135]

Answer:

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

$LM + MN = LN$ (segment addition postulate)

$5x + 4x = 9$ (substitution)

Solve for x

$9x = 9$

Divide both sides by 9

$\frac{9x}{9} = \frac{9}{9}$

$x = 1$

MN = 4x

plug in the value of x

MN = 4(1) = 4

Two increased by three equals the quotient of ten and two.

Marrrta [24]

Answer: 5 = 5 or true its an equal equation.

Step-by-step explanation:

The equation would look like this: 2 + 3 = 10 divided by 2. This equation is extremely easy it turns out to be 5 = 5 because 2 + 3 = 5 and 10 divided by 2 is 5 so your final answer is 5 = 5 or if its a true or false question, the answer is true it is an equal equation.
