Answer:

5/8

Step-by-step explanation:

The sectors are labeled 1,2,3,4,5,6,7,8

Numbers less than 4: 1,2,3

Multiples of 4: 4,8

We are looking for 1,2,3,4,8  = 5 choices

P (1,2,3,4,8) = Number of choices/ total

                  = 5/8

What percent of 160 is 56?
kakasveta [241]
160 = 100%
56 = x%

then you would cross multiply

160x = 56(100)

160x = 5600

x = \frac{5600}{160}

x = 35

so

35% of 160 is 56.

Y=3x +4<br> How do you graph this
rodikova [14]

Answer:

Step-by-step explanation:

you can use desmos to see the graph

but 4 is the y intercept, so that means you can start from the point (0, 4). then, to draw the rest of the line,  you would go up 3 and right 1 because the slope is 3 or 3/1

I want to know the work of this, like the process. Please
pogonyaev
In this question, you know that the machine packs \frac{2}{3} of a box every \frac{1}{2} of a minute. Since it is constant, you simply have to double the half a minute to a full minute and then also double the rate to get \frac{4}{3} boxes packed per minute. And \frac{4}{3} is equal to 1\frac{1}{3}

Answer:

(4,-8) and (4, 12)

Step-by-step explanation:

The equation of the hyperbola given is:

\frac{(y-2)^2}{64}-\frac{(x-4)^2}{36}=1

The general form of this hyperbola would be:

\frac{y^2}{a^2}-\frac{x^2}{b^2}=1

Thus, we can see that:

a^2 = 64

a = 8

and

b^2 = 36

b = 6

The distance from one focus to center is called "c", it goes by formula:

c^2=a^2+b^2

Let's find c:

c^2=8^2 + 6 ^2\\c^2=100\\c=10

This is a vertical hyperbola and the center is found from the x and y's on the numerator:

(y-2)^2 means y = 2

(x-4)^2 = x = 4

Center is (4, 2)

We go 10 units vertically up, so from y = 2 , ten units up makes it y = 12

x = 4 and y = 12

(4,12)

We go 10 units vertically down, so from y =2, ten units down makes it y = -8

x = 4 and y = -8

(4, -8)

<u>Foci coordinates:</u>

<u>(4,12) and (4,-8)</u>
