Answer: b
Step-by-step explanation:
Mai is flying a plane at an altitude of 1600 ft. She sights a stadium at an angle of
depression of 35°. What is mai’s approximate direct distance to the stadium?
Answer:
2,789ft
Step-by-step explanation:
The set up will give a right angled triangle.
The altitude will be the opposite side = 1600 ft
The angle of depression = 35°
approximate direct distance to the stadium is the hypotenuse of the trisngle= x
Using the SOH trig identity to get the distance
sin 35 = opp/hyp
sin 35 = 1600/x
x = 1600/sin35
x = 1600/0.5736
x = 2,789.4ft
Hence mai’s approximate direct distance to the stadium is 2,789ft

The temperature on Mars may reach a high of 70 degrees Fahrenheit at the equator in the summer. It may reach a low of -225 degrees Fahrenheit at the poles. Which expression gives the difference between those temperatures?
Answer: See explanation
Step-by-step explanation:
Since we are informed that the temperature on Mars may reach a high of 70 degrees Fahrenheit at the equator in the summer and may also reach a low of -225 degrees Fahrenheit at the poles.
The expression that gives the difference between those temperatures would then be calculated as:
= 70°F - (-225°F)
= 70°F + 225°F
= 295°F
Can someone please help me with this!?
Answer:
Step-by-step explanation:
triangles have always total degrees as 180 degrees
let the 3 rd angle be x
so , 70 + 62 + x = 180
70 + 62 = 132
132 + x = 180
x = 180 - 132
x = 52 degrees

A group of friends went fishing. They each caught 20 fish but not all of them were keepers. Which person was able to keep 3/5 of the fish that he or she caught?
Answer:
Those who were able to keep 12 fishes
Step-by-step explanation:
Given
Total = 20 (each)
Required
Which was able to keep 3/5
First, we need to calculate 3/5 of the total number of fishes
Fish = 3/5 * 20
Fish = (3 * 20)/5
Fish = 60/5
Fish = 12
From the calculation above, only those who keep 12 of the 20 fishes were able to keep 3/5 of their fishes
Find the smallest possible integer value of k for which 264k is a perfect square.
Step-by-step explanation:
264k
= 2³ * 3 * 11 * k
Hence, k = 2 * 3 * 11 = 66.
Answer:
k = 66.
Step-by-step explanation:
Find the prime factors of 264
264 = 2 * 2 * 2 * 3 * 11
The nearest perfect square will contain one more 2, one more 3 and one more 11
= 264 * 2 * 3 * 11
= 17424.

1. 3 cans of pudding costs $2.48 at Store A and 6 cans of the same pudding costs $4.50 at Store B. Which store has the better buy on these cans of pudding?
Answer:a
Step-by-step explanation:
Answer:
Store B because if you take 2.48 divided by 3 to figure out the cost per can aka one can it will be 0.826 repeating and that's for store A . While store B you take 4.5 divided by 6 to and get 0.75 per can so Store B is the best option since 0.75 is smaller than 0.826.
