Answer:
≈ 11.4 m
Step-by-step explanation:
The diagonal splits the rectangle into 2 right triangles , with legs 7 and 9 and the diagonal the hypotenuse.
Using Pythagoras' identity with h as the diagonal, then
h² = 7² + 9² = 49 + 81 = 130 ( take the square root of both sides )
h = ≈ 11.4 m ( to the nearest tenth )
Answer:
57.5
Step-by-step explanation:
Answer:
PART A:
272 teenagers that like hard rock music.
You need to find 32% of 850. To do so, you multiply .32 or 32% (same thing) by 850. 850 x 32% = 272
PART B:
175 students surveyed.
They tell us that 75% of students is 150. We need to find the remaining 25% because 75% + 25% = 100% and 100% is the total amount we need or just a whole. 25% of 100 is 25. We find this by multiplying .25 by 100. We add the 75% or 150 plus the 25% or 25 to get 175
PART C:
Your weekly allowance in 15$ but one week you do extra chores giving you 5 more dollars. This adds 5 more percent because 5% of 100 is 5 (found by multiplying .05 x 100) . This makes a total of 105%.
