Answer:

About 260 seconds

Step-by-step explanation:

Tha rate is:

A: 8L/1.66666m

b: 10L/1m (converted to litres)

Divide 2400 by those rates above which:

2400 / (8/1.66666) = 500

2400 / (10/1) = 240

500 - 240 = 260

Part B what are the probabilities of each outcome in the sample space? select all that apply

zepelin [54]

Answer:

C, D, and E are correct

Step-by-step explanation:

p(2)= 1/6; p(3)= 1/6; p(4)= 1/6; 1/6=1/6=1/6

p(1)= 3/6; 3/6=1/2

p(4) = 1/6; There are six sections and one section is labeled<em> '4' </em>

the measurements of a photo and it's frame are shown in the diagram. Write a polynomial that represents the width of the photo.

suter [353]

Answer:

The width of the photo is $4w^2+6w+4$ .

Step-by-step explanation:

From the given figure it is notices that the total width of the frame is

$6w^2+8$

The photo is covered by a frame border and the width of the border is

$w^2-3w+2$

To find the width of the photo we have to subtract the width of upper frame border and lower frame border from the total width of frame.

Width of the photo is

$\text{Width of the photo}=\text{Width of the frame}-2(\text{Width of the frame border})$

$\text{Width of the photo}=6w^2+8-2(w^2-3w+2)$

$\text{Width of the photo}=6w^2+8-2w^2+6w-4$

$\text{Width of the photo}=4w^2+6w+4$

Therefore the width of the photo is $4w^2+6w+4$ .

This jar has 1 red, 74 yellow, and 25 green gumballs. What are the chances of picking a green gumball? the red one?

kari74 [83]

Answer: green = 25/100, red = 1/100

Step-by-step explanation: add ALL of the gumballs, there's your denominator, now you have 0/100 (1+74+25), count the amount of marbles you want to get the probability of, lets say green, there's your numerator (25) = 25/100

4. (10 points) From the given triangle:

katrin2010 [14]

Answer:

sinθ = y/r sinθ = $\frac{-6}{10} = \frac{-3}{5}$

cosθ = x/r cosθ = $\frac{8}{10} = \frac{4}{5}$

tanθ = y/x tanθ = $\frac{-6}{8} =\frac{-3}{4}$

cscθ = r/y cscθ = $\frac{-5}{3}$

secθ = r/x secθ = $\frac{5}{4}$

cotθ = x/y cotθ = $\frac{4}{3}$

explanation:

r = $\sqrt{(8)^{2}+(-6)^{2} }$

r = 10

x = 8

y = -6

r = $\sqrt{(4)^{2}+(3)^{2} }$

r = 5

x = 4

y = 3
