To find the probability, you have to divide the number of horses in the barn by the total number of horses.

Number of horses in the barn = 13
Total number of horses = 39

Divide:

13 ÷ 39 = 0.33

0.33 = 33% 

Answer = 33%(3rd choice)

Hope this helped :)

To find the probability of selecting a horse in the barn, we need to know the total number of horses and the number in the barn.

To find the total, add the values in the "Total" row:

16 + 11 + 12 + 39 = 78

To find the number of horses in the barn, add the values in the "In the barn" row:

4 + 2 + 7 + 13 = 26

Now divide 26 by 78 to find the probability:

26/78 = 1/3 or about 33%

The answer is 33%

If y varies directly as x and y = 36 when x=9 find the value of y when x=3
Temka [501]
I think the answer is 12

because
y=36, x=9
y=?, x=3
so you divide 36 by 3 to get the other y

Using the standard 28/36 guidelines, what is the maximum mortgage payment allowed for someone with an annual salary of $60,750?
Anna11 [10]

\frac{28}{36} rule says that 28 % of your total income should be spent on Housing finances and 36 % of your gross total income should be spend for Debts.

Annual Salary = $ 60,750

Maximum mortgage payment=28% of $ 60,750

=\frac{28}{100} \times 60750=\frac{1701,00}{100}\\\\ =1701

Maximum ,mortgage payment allowed for someone with an annual salary of $60,750= $ 1,701.00→→→Option (C)

Answer:

404 cm³ Anyway... Look down here for my explanation.

Step-by-step explanation:

Let's Draw a line from the center of the circle to one of the ends of the chord (water surface) and another to the point at greatest depth on your paper. A right-angled triangle is formed too. The Length of side to the water-surface is 5 cm, the hospot is 7 cm.

We Calculate the angle θ in the corner of the right-angled triangle by: cos θ = 5/7 ⇒ θ = cos ˉ¹ (5/7)

44.4°, so the angle subtended at the center of the circle by the water surface is roughly 88.8°

The area shaded will then be the area of the sector minus the area of the triangle above the water in your diagram.

Shaded area 88.8/360*area of circle - ½*7*788.8°

= 88.8/360*π*7² - 24.5*sin 88.8°

13.5 cm²

(using area of ∆ = ½.a.b.sin C for the triangle)

Volume of water = cross-sectional area * length

13.5 * 30 cm³

404 cm³

Please I need help !!!!!
Mama L [17]
The formula is y=0.5m+20

You start (0,20) then for each mile you increase by 0.5.
Or
Since the x axis is by two, then every two miles you increase by 1 mile. So (0,20); (2,21); (4,22); (6,23); (8,24).
