You collect a total of $80 in donations from three people. The three donations are in the ratio 3 : 3 : 10.

1 answer:

7 0

ratio 3 : 3 : 10
3+3+10 = 16

80/16 = 5

so 3* 5 = 15
10*5 =50

ratio 3 : 3 : 10 = 15 : 15 : 50

Seth traveled one mile in 57.1 seconds. About how fast does Seth travel in miles per hour?

ZanzabumX [31]

Since we need to convert “miles per second” to “miles per hour,” we first need to find out how many seconds there are in a hour.
We know that there are 60 seconds in a minute, and if we wanted to do an hour we would have to do 60 * 60 which is 3600 seconds, therefore,
1 mi/57.1 sec = (1 mi/ 57.1 sec)(3600 sec/1 hour)

= (3600/57.1) mi/hours

 = 63.047 mi/hours

The equation of line AB is (y−3) = 5 (x − 4). What is the slope of a line perpendicular to line AB?

Darina [25.2K]

Answer:

The perpendicular slope would be -1/5.

Step-by-step explanation:

This is because we can locate the slope of the original line as 5 (the number just outside of the x-coordinate parenthesis.

Then we know that perpendicular lines have opposite and reciprocal slopes. So we take the 5 and change the sign (-5), then we flip it (-1/5).

The table below gives the distribution of milk

coldgirl [10]

Answer:

0.16

Step-by-step explanation:

Step 1:

Data obtained from the question. This include:

Probability of brown, P(Br) = 0.13

Probability of red, P(R) = 0.13

Probability of yellow, P(Y) = 0.14

Probability of green, P(G) =..?

Probability of orange, P(O) = 0.2

Probability of blue, P(B) = 0.24

Step 2:

Determination of the probability of green candy

Space = {brown, red, yellow, green, orange, blue}

Probability of sampl space, P(S) = 1

P(S) = P(Br) + P(R) + P(Y) + P(G) + P(O) + P(B)

1 = 0.13 + 0.13 + 0.14 + P(G) + 0.2 + 0.24

1 = 0.84 + P(G)

Collect like terms

P(G) = 1 – 0.84

P(G) = 0.16

Therefore, the probability of green candy is 0.16

Enter the equation of the parabola in vertex form that has its vertex at (4,–13) and passes through the point (6,–5).

Vika [28.1K]

Answer:

Step-by-step explanation:

If you plot the vertex and the point that it goes through, the point it goes through is above the vertex, so the vertex is a positive one that opens upwards. The general vertex form of a parabola of this type is

$y=a(x-h)^2+k$

We have the x, y, h, and k. We will plug all those in and solve for a. That looks like this:

$-5=a(6-4)^2-13$ which simplifies to

-5 = 4a - 13 and

8 = 4a so

a = 2

That means that the paraobola in vertex form is

$y=2(x-4)^2-13$
