None of these are true roots.

a. The closest true root to √50 is 7.

7^2 = 49

b. The closest true root to √150 is 12.

12^2 = 144

c. The closest true root to √350 is 19.

19^2 = 361

d. This is a cubed root, rather than a square root.

The closest root to 3√350 is 7.

7^3 = 343

How do I subtract a whole number from a fraction

jasenka [17]

Answer:

In order to subtract a whole number from a fraction, you first have to turn the hole number into a mixed fraction.

Step-by-step explanation:

Say your fraction was 2/3 and your whole number was 5.

They have to have like denominators

5/1 - 2/3 = 15/3 - 2/3

15/3 - 2/3 = 13/3

13/3 = 4 1/3

2√m^2 if m is greater than or equal to 0

iris [78.8K]

Answer:

$\displaystyle \boxed{|2m| }$

Step-by-step explanation:

we are given that

$\displaystyle 2 \sqrt{ {m}^{2} }$

since m is greater than or equal to 0 it's a positive number therefore, the square root of m is defined and recall that √x²=|x| thus

$\displaystyle \boxed{2 |m|}$

remember that,|a|•|x|=|ax| hence,

$\displaystyle \boxed{ |2m|}$

and we're done!

68% of johns school are boys. There are 180 more boys than girls. How many students are there in johns school

Ghella [55]

Answer:

500 students in the school

100 - 68% = 32%

boys percentage 68%

girls percentage 32%

difference 68 - 32 = 36% = 180

36 ÷ 18 = 2 × 50 = 100

180 ÷ 18 = 10 × 50 = 500

Solve the equation. Then check your solution

kondaur [170]

Answer:

Option B is correct i.e. 21

Step-by-step explanation:

In the question we're provided with an equation that is :

v/7 = 3

And we are asked to find the solution for the equation .

Solution : -

 $\longrightarrow \: \frac{v}{7} = 3$ 

Multiplying by 7 on both sides :

$\longrightarrow \: \frac{v}{ \cancel{7} }\times \cancel{7} = 3 \times 7$

On further calculations , we get :

$\longrightarrow \: \blue{\boxed{v = 21}}$

Therefore , solution for equation is 21 .That means option B is the correct answer.

Verifying :

We are verifying our answer by substituting value of v in the equation given in question :

$\longrightarrow \: \frac{v}{7} = 3$

Putting value of v :

$\longrightarrow \: \cancel{\frac{21}{7}} = 3$

By dividing 21 with 7 , we get :

$\longrightarrow \:3 = 3$

$\longrightarrow \: L.H.S=R.H.S$

$\longrightarrow \: Hence , \: Verified.$

Therefore , our answer is valid .
