Answer:
Building B, it is around 16 35 feet taller than building A ( C )
Step-by-step explanation:
<u>Calculating the height of Building A </u>
Height = opposite ( ? )
∅ = 73°
base/adjacent = 30 ft
∴ Height = Tan 73° * base
= 3.2709 * 30 = 98.127 ft
<u>Calculating the height of building B </u>
∅ = 73°
base/adjacent = 35 ft
∴ height = Tan 73° * base
= 3.2709 * 35 = 114.4815
Therefore we can say Building B is Taller by approximately 16.35 feet
Given:
The fees for a day student are $600 a term.
The fees for a boarding student are $1200 a term.
The school needs at least $720000 a term.
To show:
That the given information can be written as .
Solution:
Let x be the number of day students and y be the number of boarding students.
The fees for a day student are a term.
So, the fees for day students are a term.
The fees for a boarding student are a term.
The fees for boarding student are a term.
Total fees for day students and boarding student is:
The school needs at least $720000 a term. It means, total fees must be greater than or equal to $720000.
Divide both sides by 600.
Hence proved.
Answer:
A-
First we do 72/88 to get the percentage. When the math is done you get 81.81% so that means that Will got an 81.81% on the test.
B-
Now we will do 81/88 to get the percentage because Cheng got 81 points. When that math is done we see that Cheng got a 92.04% on the test.
C-
To get Rob's percentage we need to do 75/88 because Rob got 75 points. When we calculate that we recieve 85.23% meaning he got that on the test.
D-
Now to figure out who got the highest percentage and who got the lowest is simple. The max points doesn't change so it varies on who got the highest and lowest points. We can see that Cheng received the highest with 81/88 (92.04%) and Penny received the lowest with 68/88 (77.27%).
