Help I guess? sorry I'm asking a lot of questions today
valina [46]

Answer:

63 houses have been sold this year.

Step-by-step explanation:

There are 81 houses in the community. If 7/9 are sold this year, then all you have to do is multiplication.

In this case, you would multiply 81 by 7/9 to get your answer.

81/1 x 7/9:

Cancel out the 9 and the 81. Then the denominator will be 1 x 1 and the numerator would be 7 x 9. It would be 63 (7x9=63) over 1 (1x1=1) which is just 63. Make sure to include units.

romanna [79]

Answer:

33/100 red, 29/100 blue

Step-by-step explanation:

2/10=20/100

20+18=38

33/100 red, 29/100 blue.

Answer:

(x+15)^2+(y-11)^2=4

Step-by-step explanation:

<u><em>The question is</em></u>

How do you write an equation for a circle with center (-15,11) and radius 2?

we know that

The equation of a circle in center radius form is given by

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center of the circle

r is the radius of the circle

substitute the given vales

(x+15)^2+(y-11)^2=2^2

(x+15)^2+(y-11)^2=4

he volume of a fish tank is 50 cubic feet. If the density is 0.2 fish over feet cubed, how many fish are in the tank?
V125BC [204]

There are 10 fish in the tank

<em><u>Solution:</u></em>

Given that, volume of a tank is 50 cubic feet

Density is 0.2 fish over feet cubed

<em><u>To find: Number of fish in the tank</u></em>

Number of fish in the tank is found by multiplying the volume of tank and density

<em><u>The formula is given by:</u></em>

\text{Number of fish} = \tex{\text{volume of tank}} \times {\text{density of fish over feet cubed}}

<em><u>Substituting the given values, we get</u></em>

\text{Number of fish} = 50 ft^3 \times \frac{\text{ 0.2 fish}}{ft^3}\\\\ \text{Number of fish} =  50 \times 0.2 \text{ fish }\\\\ \text{Number of fish} = 10 \text{ fish }

Thus there are 10 fish in the tank
