Answer:

$\dfrac{\sqrt{10}}{4}$

Step-by-step explanation:

$\sqrt{\dfrac{5}{8}} =$

$= \dfrac{\sqrt{5}}{\sqrt{8}}$

$= \dfrac{\sqrt{5}}{\sqrt{4 \times 2}}$

$= \dfrac{\sqrt{5}}{2 \sqrt{2}}$

$= \dfrac{\sqrt{5}\sqrt{2}}{2 \sqrt{2}\sqrt{2}}$

$= \dfrac{\sqrt{10}}{2 \times 2}$

$= \dfrac{\sqrt{10}}{4}$

You preform an experiment to determine how many breaths a fish takes per minute. Your experiment yields the following data: minu

Alex777 [14]

Alright, lets get started.

experiment yields the following data: minute 1: 65 breaths; minute 2: 73 breaths; minute 5: 62 breaths

Total number of breaths = $65+73+62 = 200$

Total minutes observes = 3 minutes

So, average breaths per minute will be = $\frac{200}{3}=66.67$

So, the average number of breaths that a fish takes per minute is 66.67. : Answer

Hope it will help :)

After an office party, 4 1/3 pizzas are left. A day later, there are 1 5/6 pizzas left. How munch pizza was eaten during the day

IceJOKER [234]

Answer:

15/6 pieces of pizza were eaten. Which is equivalent to 2.5. So 2.5 pizzas were eaten.

Step-by-step explanation:

Just did the math. Convert 4 1/3 to 0/6. So 1 times 2 is 2, and 3 times 2 is 6. Which would give you 4 2/6 which has the same denominator as 1 5/6.

Two towns that are 31.5 km apart are 3 cm apart on a map. what is the scale of the map?

VLD [36.1K]

Answer:

1 cm : 10.5 km

Step-by-step explanation:

We are given that two towns are 31.5 km in real and are 3 cm apart on a map and we are to find the scale of the map.

For this, we can use the ratio method.

$\frac { 3 cm } { 1 c m } = \frac { 3 1 . 5 k m } { x }$

$x = \frac { 3 1 . 5 \times 1 } { 3 }$

$x = 1 0 . 5$

Therefore, the scale of the map would be 1 cm : 10.5 km.

Pls answer I will give brainliest

Levart [38]

Answer: 108 ft³

Step-by-step explanation:

V= 4/3πr³

Facts:

Pi= 3

Diameter = 6

Step1; find the radius

Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.

1/2 of 6= 1/2x6= 3.

R= 3

Step 2: Plug in the numbers (into the formula)

PEMDAS

(exponents go first)

(then multiply from left to right)

V= 4/3πr³

V= 4/3x3x3³

V= 4/3x3x (3x3x3)

V= 4/3x3x27

V= (4/3x3) x 27

V= 12/3x27

V= 4x27

V= 108

Volume= 108 ft³

Hope this helps :)) Also brainliest would be appreciated, i worked pretty hard on this thanks! :)
