Step-by-step explanation:
Your answers for 1 and 2 are correct. MN and LN are both radii of the circle, and therefore equal. And NK can be found using Pythagorean theorem.
To find LP (and PM), we can use similar triangles:
LN / NK = LP / LK
10 / 26 = LP / 24
LP ≈ 9.23
PM ≈ 9.23
LM ≈ 2 × 9.23 = 18.46
To find NP, we can again use similar triangles.
NP / NL = NL / NK
NP / 10 = 10 / 26
NP ≈ 3.85
NQ is a radius of the circle, so it is equal to 10. PQ is therefore:
PQ ≈ 10 − 3.85 = 6.15
As you found, QK = 26 − 10 = 16.
Before we find LR, let's find RK using similar triangles.
RK / QK = NK / LK
RK / 16 = 26 / 24
RK ≈ 17.33
LR ≈ 24 − 17.33 = 6.67
As you found, MK = 24.
And finally, MS = LR ≈ 6.67.
They arent. first is correct but second isn’t. 329 000 x 100 = 329 000 000. however if u wanted to get 3290, it would be 329 000 / 100. hope this helps! :)
Answer:
C 44.59
Step-by-step explanation:
The first two shirts are full price
2*49.96 = 99.92
The third shirt is 50% off. That means it is 50% of the original price
.5*49.96 = 24.98
The total cost before tax is
99.92+24.98 =124.90
tax = cost * tax rate
tax = 124.90*.071
tax=8.87
Add this to the cost
final cost = 124.90+8.87
=133.77
We want to find the mean cost (average cost)
Take the total cost and divide by the number of shirts
133.77/3 =44.59
<u><em>Answer:</em></u>
Nelson burned the most calories per hour
<u><em>Explanation:</em></u>
To solve this question, we will get the amount calories burned by each in one hour and then compare the two values
To do this, we will divide the total amount of calories burned by the total time
<u>1- For Sabra:</u>
We are given that she burnt 845 calories in
(which is equivalent to 3.25) hours
<u>Therefore:</u>
Calories burnt in an hour =
calories/hour
<u>2- For Nelson:</u>
We are given that he burnt 1435 calories in
(which is equivalent to 4.875) hours
<u>Therefore:</u>
Calories burnt in an hour =
calories/hour
<u>3- Comparing the two values:</u>
From the above calculations, <u>we can deduce that</u> Nelson burned the most calories per hour
Hope this helps :)
