The answer is B. 1/3


√5/√45 <— simply both terms by 5

= √1/√9 <— √5÷5 = 1 and √45 ÷ 5 = √9

= 1/√9

= 1/3



√1 = 1
(you can write 1 directly instead of √1)

√9 = 3

find the height and of a parallelogram if its base is 35 centimeters and its area is 700 square centimeters
OLEGan [10]
Hello!

We know what the base and area of the parallelogram are, but the height is still unknown. We also know that the formula for the area is: 

A = bh

Meaning we multiply the base by the height to find the area. The opposite of multiplication is division, so we must divide the area by the base to find the height. (We work in the opposite way).

B = a / h 

B = 700 cm² / 35 cm

B = 20 

We can double check by multiplying 20 by 35, and the product should result in 700. 

20 * 35 = 700

Therefore, the height of the parallelogram is 20 centimetres.

Use distributive property to rewrite problem so it had only two factors. Then solve (25x9)+(75x9)=
Shalnov [3]

ANSWER

(25\times9)+(75\times9)=9(25+75)


(25\times9)+(75\times9)=9(100)


(25\times9)+(75\times9)=900


EXPLANATION


According to the distributive property,

(a\times b)+(a\times c)=a(b+c)

This implies that,

(25\times9)+(75\times9)=9(25+75)


(25\times9)+(75\times9)=9(100)

The Right Hand Side of the equation now has 2 factors.


We solve now to obtain;


(25\times9)+(75\times9)=900

The owner of the plant nursery where you work tells you to fill 350 milliliter bottles from a 30 liter drum of fertilizer. How m
valina [46]
So we know that there are 1000 mL in 1 L. We can set up an equation that allows us to solve for how many bottles are needed in order to empty the 30 L tank:

\frac{1 bottle}{350 mL}*  \frac{1000 mL}{1 L}* \frac{30 L}{1 tank}

This equation then allows us to cancel out the units of mL and L, leaving us with how many bottles are needed per tank. Then we multiply straight across to give us:

\frac{30,000}{350}= \frac{85.71 bottles}{1 tank}

The question asks us to round up to the next whole number, so it would take 86 bottles to empty one 30 L tank.
