8/13 and 7/10.

Answers

Answer 1
Answer: to find the rational number inbetween those 2 numbers you have to find the average, so 8/13 plus 7/10= 1.315384615384615, than divide that by 2 which equals 0.657692307692308 (0.658 rounded)

0.648 is the rational number inbetween 8/13 and 7/10

Find an equivalent function to f(x) = 5(3)3x. f(x) = 125x(27)x
f(x) = 152x
f(x) = 5(27)x
f(x) = 135x

Answers

If you would like to find an equivalent function to f(x) = 5(3)^(3x), you can do this using the following steps:

f(x) = 5(3)^(3x) = 5(3^(3x)) = 5(27)^x = 5(27)x

The correct result would be f(x) = 5(27)x.

Answer:

The correct result would be f(x) = 5(27)x.

What is the length of BC in the right triangle below 21 and 72

Answers

Im guessing 21 and 72 are the side lengths for the triangle?

Alright, so since it's a right triangle you can use the Pythagorean theorem or a^2+b^2=c^2

Since i cant see the picture, im going to use some general math so i can figure out if those two sides are the legs or if one of them is the hypotenuse
Alright 
so im guessing the side we're trying to find is the hypotenuse

21^2+72^2=c^2
441+5184=c^2
5625=c^2
√5625=c
75=c

The answer is 75, hope i helped!

Question 1.1. Choose the correct answer.Nancy bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as angelfish. How many of each type of fish did she buy?

Which is a system of equations to model the problem if x represents the number of angelfish Nancy bought and y represents the number of goldfish she bought?

(Points : 1)
x – y = 360
y = 8x

x + y = 360
y = 8x

x + y = 8
y = 360x

x + 8y = 360
y = 8x

There are 23 Birds and then Avery at the zoo. If each bird drinks the same amount of milliliters of water how much do how much do they drink if the zoo use of 16.215 L. (There are 1000 ml in a liter)

Answers

Answer:

Each bird drinks 705 millimeters of water

Step-by-step explanation:

Total number of Birds = 23

Volume of water in the zoo = 16215 millimeters

Therefore each bird will have 16215 ÷ 23 = 705 millimeters

Answer: each bird drinks 705 milliliters

Step-by-step explanation:

We know that the birds drink 16.215L, and 1L is equal to 1000ml, in 16.215L we have:

16.215*1000ml = 16215ml

And we also know that 23 birds drink that amount, and each bird drink the same amount, so each bird drinks

V = 16215ml/23 = 705ml

So each bird drinks 705 milliliters
