A circular cake is 360 degrees if you eat a piece that is 40 degrees of the cake, how many degrees are left in the cake?

Mathematics

ololo11 [35]2 years ago
7 0

Step-by-step explanation:

a whole circle is 360°.

if you take away 40°, how many are left ?

that is absolutely the same as the question, when I have 15 apples and 6 are eaten, how many are left ?

well, 15-6 = 9 apples are left.

and so, 360-40 = 320° are left.

The table represents an exponential function.
Mama L [17]

Answer:

Step-by-step explanation:

All we are doing here is solving for the b in

y=a(b)^x, which is the standard form for an exponential function.

Use the first 2 coordinate pairs to solve for b: (1, 6) and (2, 4):

6=a(b)^1 so

a=\frac{6}{b} and use that when you write the next equation using the next coordinate pair:

4=\frac{6}{b}(b)^2 which simplifies to

4 = 6b so

b=\frac{2}{3}, the second choice there. Another way of saying multiplicative rate is the rate of decay or the rate of growth. Same thing. This is decay since 2/3 is greater than 0 but less than 1.

Help fast please ??!!
Rama09 [41]

Answer:

Area =  1053.59²

Step-by-step explanation:

Area = Area of cylinder + Area of rectangular prism

Area of cylinder = 2 π r h + 2 π r²             [ r = 4, h = 8]

                        = 2 π r ( h + r)

                        = 2 π x 4 ( 8 + 4)

                        = 301.59 ft²

Area of rectangular prism = 2 ( 12 x 8 + 8 x 14 + 14 x 12)  = 752 ft²

Area = 301. 59 + 752 = 1053.59²

Raphael had 5 hits in 7 at bats. If he continues this pattern, how many hits will he have in 210 at bats?
devlian [24]

So it tell us that he is able to get 5 hits out of 7 and to find how much he could make if 210 chances
\frac{5}{7} = \frac{x}{210}

We solve what can be solved
0.7 = \frac{x}{210}

Then we leave our variable alone
0.7 *210=x

Last we solve
x=147

In this case we can see that he could make 147 hits out of 210 bats.
