Ali a Gardner is preparing to fertilize your lawn. The lawn is 30 yards by 25 yards. One bag of fertilizer will cover an area of

100 square yards. How many bags of fertilizer does Ali need to buy?

So first we need to figure out the area of the lawn:

Area= l*w
A= 25*30 =750

This means that one bag of fertilizer will only cover about 1/7 of the entire thing so we will need 8 bags of fertilizer because
750/100 = 7.5 but since you can't have half a bag of fertilizer you round up to 8.

NGC is a hot air balloon in the sky from her spot on the ground. The angle of elevation from Angie to the balloon is 40°. If she

Goshia [24]

Answer:

The distance from hot air balloon to the ground $AC=50.1457 ft$ .

Step-by-step explanation:

Labelled diagram of given scenario is shown below.

Given that,

An angle of elevation of Hot air balloon by Angie is $40$ °.

When she stepped back $200 ft$ then angle of elevation was $10$ °.

Height of Angie is $5.5 ft$ .

To find: How far off the ground is a hot air balloon.

So, from figure

Height of Angie $(BC) = 5.5ft$

In triangle Δ $ABD$ ,

⇒ $tan {40\si {\degree}} = \frac{AB}{BD}$

⇒ $AB = tan (40) \times BD$ ....................(1)

Now, In triangle Δ $ABE$

⇒ $tan (10)= \frac{AB}{200+BD}$

⇒ $AB = tan(10)\times (200+BD)$

Here, substituting the value $AB$ from Equation (1) we get,

$tan(10)\times (200+BD)= tan(40)\times BD$

$tan(10)\times 200+tan(10)\times BD= tan(40)\times BD$

⇒ $BD\times (tan(40)-tan(10))=tan(10)\times 20$

⇒ $BD\times 0.6628 = 35.2654$

⇒ $BD = \frac{35.2654}{0.6628} =53.2067 ft$

Now, finding the value of $AB$ from equation (1)

$AB= tan(40)\times 53.2067=0.8391\times 53.2067$

$AB=44.6457 ft$

Therefore Length of $AC= AB+BC$ = $(44.6457 + 5.5) ft$

$AC=50.1457 ft$ .

Hence,

The distance from hot air balloon to the ground $AC=50.1457 ft$ .

What is the value of x?

adoni [48]

$3x = x + 40 \\ 3x - x = 40 \\ 2x = 40 \\ x = \frac{40}{2} \\ x = 20$
The answer is x = 20

Your teacher is giving a test worth 200 points. There is a total of 30 five-point and ten-point questions. How many five-point q

densk [106]

Answer: there would be 20, 5 point questions.

Step-by-step explanation:

There are 30 questions, all equaling out to 200 points. you can't have 20, 10 point questions because that would equal 200 points all by its self. So, you would do 10, 10 point questions, and 20, 5 point ones because 20 times 5 is 100, ad that 100 plus the other 100 from the 10 point questions would e 200. I hope this helps :)
