First of all, Jamie's room is really weird. Second of all, let's solve. Since the formula for the area of a circle is (pi)r^2, and Jamie's room is exactly half of that, the area for a semicircle would be (1/2)(pi)r^2. The straight wall is the diameter, so half of the diameter would be the radius. Half of 14 is 7. Now, you rewrite the equation and substitute the values of the variables. The new equation (if you're using 3.14 for pi) is (1/2)(3.14)(7^2), or (1/2)(3.14)(49). From here you can solve, so the answer would be 76.93. Jamie needs 76.93 square feet of carpet.
Answer:
1240
Step-by-step explanation:
Number of boys to a girl is
x:y= 11:9
9x= 11y
There are 124 more boys in the schooll than girls
x= 124+y
Substitute 124+y for x
9(124+y)= 11y
1116+9y= 11y
1116= 11y-9y
1116= 2y
y= 1116/2
y= 558
Number of girls is 558
The number of boys can be calculated as follows
= 558+124
= 682
Hence the total number of students is
= 682+558
= 1240
Answer:
$419.4
Step-by-step explanation:
When on off, the price would be
Additional 10% off would imply 90% of the price after 1/3 off hence
0.9*$466=$419.4
Therefore, the cost of chair after discounts is $419.4
Answer:
8/25
Step-by-step explanation:
The total amount of tickets is 25 so divide 10 from 25 to figure out what you multiply by to get 25
--> 25/10 = 2.5
now multiply 2.5 x 3 to have a numerator which would be your probability of winners out of 25 tickets
--> 2.5 x 3 = 7.5 (round to the nearest whole number)
7.5 rounded to the nearest whole number --> 8
so you get 8 out of 25 = 8/25
Given:
Weight of one peach = 65 grams
Number of peaches in a box = 100
Cost of peach per kilogram is AED.10.
To find:
How much you have to pay?
Solution:
We know that,
Total weight of box = Weight of one peach × Number of peaches in a box
= 65 × 100
= 6500 grams
1000g = 1 kg
1 g = 0.001 kg
6500 g = 6500 × 0.001 kg
= 6.5 kg
Now,
Cost of 1 kg = AED.10
Cost of 6.5 kg = 6.5 × AED.10
= AED.65
Therefore, you have to pay AED. 65.
