260/4 = 64 so the answer to the first question is y=64x, the answer to the second question is y (the answer), and the answer to the last one is no because if you were to graph it, it would not go through the origin (0,0)

√64/169 Evaluate. IDK

Answers

I can't tell if '169' is also inside the radical.

If it is, then the fraction is the same as ( √64 / √169 ) .
You can easily find both of those square roots, and
the result is (8 / 13) = about 0.6154... (rounded).

If the '169' is NOT inside the radical, then you have (√64) / 169 .
You know what the square root of 64 is, so the result is

8 / 169 = about 0.04734... (rounded)

A builder planned to build houses. Each house will be built on 5/6 of an acre. How much land would be needed for 7 houses? The builder began with 10 acres of land . After 7 houses were built, how much land was left unused?

Answers

Answer:

$5(5)/(6)\approx 5.833$ acres of land would be needed for 7 houses.

$(25)/(6)\approx 4.17$ acres of land was left unused.

Step-by-step explanation:

We have been given that each house will be built on 5/6 of an acre.

To find the area it will take to build 7 houses, we will multiply area need to build one house by 7 as:

$(5)/(6)* 7$

$(35)/(6)$

$5(5)/(6)\approx 5.833$

Therefore, $5(5)/(6)\approx 5.833$ acres of land would be needed for 7 houses.

Since builder began with 10 acres of land, so we can find the unused land by subtracting $5(5)/(6)$ from 10 as:

$10-5(5)/(6)$

$10-(35)/(6)$

$(10*6)/(6)-(35)/(6)$

$(60)/(6)-(35)/(6)$

$(60-35)/(6)$

$(25)/(6)$

$(25)/(6)\approx 4.17$

Therefore, $(25)/(6)\approx 4.17$ acres of land was left unused.

For 7 houses you will need 5.83 acres of land and the builder will have 4.16 acres of land unused

How do you solve this equation: 18k - 4k = -10 -4k

Answers

18k - 4k = -10 - 4k
18k - 4k + 4k = -10
18k = -10
k= (18/10) = (9/5) = 1.8

18K-4k= -10-4K
18k-4k +4k =-10
18k18=-10/18
k=-.555556

In a video game,a guppy that escapes a net turns into three goldfish.Each goldfish can turn into two betta fish.Each betta fish can turn into two angelfish.Write and evaluate an expression for the number if angelfish that can be formed from one guppy.

Answers

If g=guppy, go=goldfish, b=bettafish and a=angelfish we can set up expressions for each set of fish.
1g=3go
1go=2b
1b=2a

By working backwards and substituting we can finally work out 1 guppy to be equal to 12 angelfish.
