ratio of 9:2

 means for every 9 cows there are 2 horses

72/9 = 8

 8 x 2 = 16

 there are 16 horses

Answer:  The required number of horses at the farm is 16.

Step-by-step explanation:  Given that at a farm, the ratio of cows to horses was 9:2 and there were 72 cows at the farm.

We are to find the number of horses at the farm.

Let the number of cows and horses at the farm be 9x and 2x respectively.

Then, according to the given information, we have

\textup{number of cows}=72\\\\\Rightarrow 9x=72\\\\\Rightarrow x=\dfrac{72}{9}\\\\\Rightarrow x=8.

Therefore, the number of horses at the farm will be

2x=2\times8=16.

Thus, the required number of horses at the farm is 16.

400g of rapberries and 300g of strawberries cost £7.46. 500g of strawberries cost £4.10 work out the cost of 300g of raspberries
MAXImum [283]

Answer: £5.39

Step-by-step explanation:

500g strawberries = 4.10

100 g = 0.82

300g = 2.46

400g raspberries = 7.46 - 2.46 = 5.00

100g = 1.25

300g = 3.75

200g strawberries = 0.82 * 2 = 1.64

3.75 + 1.64 = 5.39

Which theorem would you use to prove ABE ~ DCE?
Pachacha [2.7K]
Answer: Choice C) AA similarity

------------------------------------------------------------------------------
------------------------------------------------------------------------------

We are given that angle ABE = angle ECD since they are both right angles (square marker)

Angle AEB = angle CED as they are vertical angles

we have two pairs of congruent angles, leading us to be able to use the AA (angle angle) similarity theorem

Plz explain it to me? and answer
Viefleur [7K]
The question states that both parts of Noshi's desk were shaped like trapezoids and both had a height of 3.

We know that the formula for area of a trapezoid is (a+b)/2 * h, where a and b are bases of the trapezoid and h is the height. Note: This is like any other form of trying to find the area, because we are doing base times height, however, we need to divide the sum of the bases by 2 to find the average base length.

Let's call the first trapezoid on the left Trapezoid A and the second slanted trapezoid Trapezoid B.

Area of Trapezoid A = (a+b)/2 * h = (5+8)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet
Area of Trapezoid B = (a+b)/2 * h = (4+9)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet

To find the area of Noshi's total desk, we simply need to add the areas of Trapezoid A and Trapezoid B together.

19.5 feet + 19.5 feet = 39 feet

Therefore, the area of Noshi's desk is 39 feet.

Hope this helps! :)
