$circumference = \pi d$
So it's just 622 x 3.14 (which is obviously rounded)
Or <span>1953.08</span>

What is 1.8 added 8 times? (IF YOU CAN PLS DO IT IN EXPLANATION) and this is about decimals and pls do it in grade five type, bc

Salsk061 [2.6K]

Answer:

14.4

Step-by-step explanation:

1.8 added 8 times = 1.8 * 8

1.8 * 8

use distributive property

1.8 = 1 + 0.8

1.8 * 8 = (1+0.8) * 8

= 1*8 + 0.8*8

anything multiplied by 1 equals itself

1*8 + 0.8*8 = 8 + 0.8 * 8

0.8 = 8/10

0.8 * 8 = (8/10) * 8

= 64/10

= 6.4

8 + 0.8 * 8 = 8 + 6.4 = 14.4 as our answer

The density of a fish tank is 0.3 fish over feet cubed. There are 15 fish in the tank. What is the volume of the tank?

ale4655 [162]

Since Density = mass/ volume (d = m / v), and assuming the 15 fish weigh 1 gram each - if weight of each fish isn't given - (making that a total of 15 grams),

D = m / v
0.3 = 15 / v
v = 15 / 0.3 = 50 ft cubed

Hope this answers your question correctly :)

It's a system of equations x=-4y x+6y=18

Misha Larkins [42]

Subsitute -4y for x

-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back

x=-4y
x=-4(9)
x=-36

(x,y)
(9,-36)

Make a table of values for the function rule. then graph the function. y=-x²+4

lakkis [162]

Answer:

check the attached picture

Step-by-step explanation:

Given function is $y=-x^2+4$ .

Now we need to make a table of values for the function rule then graph the function.

We are free to plug any values of x like -3,-2,-1,0,1,2,3,... etc becaues domain of polynomial function is all real numbers.

Let's plug x=1 into given function to find the y-value

$y=-x^2+4$

$y=-(1)^2+4$

$y=-1+4$

$y=3$

Hence the first point is (1,3).

Same way we can find few more points to complete the table then graph those points and connect them to get the final graph.
