the ratio of boy to girls in a school 1s 5:7. if there are 780 students in the school, how many boys are in the school?

Answers

Answer 1

Answer:

325 boys

Step-by-step explanation:

The ratio 5:7 represents 5+7=12 students. If we were to proportionalize this ratio to 780 students, we would multiply the ratio by 65/65 since 780/12=65.

Therefore, you have (5*65)/(7*65)=325/455 as your ratio. This means that there are 325 boys in the school

Answers

Answer:

  k = 2

Step-by-step explanation:

The slope formula gives the slope between two points:

  m = (y2 -y1)/(x2 -x1)

  -2 = (-2 -0)/(3 -k)

Multiplying by (3 -k) gives ...

  -2(3 -k) = -2

  3 -k = 1

  k = 3 -1 = 2

The value of k is 2.

Answer:

c

Step-by-step explanation:

smart boi

Step-by-step explanation:

A = (3, 6)

B = (6, 9)

C = (9, 3)

first scaled down (dilated) by the factor of 1/3 in the direction of the origin = point (0, 0).

then moved left by 2 units and down by 3 units.

the dilation about the origin simply multiplies each coordinate by the scale factor.

Ad = (3×1/3, 6×1/3) = (1, 2)

Bd = (6×1/3, 9×1/3) = (2, 3)

Cd = (9×1/3, 3×1/3) = (3, 1)

to move 2 units to the left means to subtract 2 from the x coordinates.

to move 3 units down means to subtract 3 from the y coordinates.

A' = (1-2, 2-3) = (-1, -1)

B' = (2-2, 3-3) = (0, 0)

C' = (3-2, 1-3) = (1, -2)

therefore, B is the right answer option.

Sienna has $40 to spend at the pumpkin patch each pony ride is $6

Answers

she can get on the pony ride 6 times, 6 x 6 = 36 and she'll have 4 dollars left over

Answer:

There is no direct question on here so I'll just assume you're asking how many rides she can get on???

Step-by-step explanation:

6 x 1 = 6

6 x 2 = 12

6 x 3 = 18

6 x 4 = 24

6 x 5 = 30

6 x 6 = 36

6 x 7 = 42

So she can get on about 6 rides (once again, if thats what ur trying to ask..)

What is the equation of this line?

y=34x−3

y=−3x−34

y=−3x−43

y=43x−3

Answers

Step-by-step explanation:

this line goes through the points (0, -3) and (4, 0).

so, the y-axis intercept is at y = -3.

therefore, the equation has to end with "- 3".

the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :

x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).

so, the slope is 3/4.

and so, the equation is

y = (3/4)x - 3

The odds against the horse Bucksnot winning the race are 1:6. What is the probability that Bucksnot will win the race?

Answers

Answer:

5:6

Step-by-step explanation:

when adding the two probabilities together, they should equal 6:6. So, 5:6 is the odds of winning.

The probability is the ratio of the favorable event to the total number of events. Then the probability that Bucksnot will win the race is 5/6.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

The odds against the horse Bucksnot winning the race are 1:6.

Then the probability that Bucksnot will win the race will be

[tex]\rm P = 1 - \dfrac{1}{6}\\\\P = \dfrac{5}{6}[/tex]

Vivi steps off a 10-foot-high diving board and goes 7 3/8 feet below the surface of the swimming pool, then back up to the surface. How far does she travel altogether

Answers

Answer:

Your answer is 24 3/4 if you want it decimal wise it would be 24.75

Step-by-step explanation:

Well, let's set up our equation first. 10 (she jumped down 10 feet) + 2(7 3/8) (we are multiplying this by 2 because she first went under the surface then went back up to the surface)

Since distance is never negative you won't add any negative symbols, you'll simply add. First 2(7 3/8) = 59/4 or 14 3/4 | Next we add 10 to it 14+10 = 24 3/4

Your answer is 24 3/4 if you want it decimal wise it would be 24.75
