Okay so if the regular price of the shirt is 100% as $25 and you have a 30% discount you are still paying 70% (100-30=70) so 70% as a decimal is .70 and $25 x .70 is $17.50. Therefore the shirt is $17.50 after the discount.
First, pass all the rate of inflation to ballons/hour
John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
Answer: option A)
Answer:
4x(x^4-7)
Step-by-step explanation:
Answer:
10 = b
Step-by-step explanation:
Begin by expanding (x + 5)^2
(x + 5)(x + 5)
First: x*x = x^2
Outside: x * 5 (the last term which is a 5)
Inside: 5+ x
Last: 5*5 = 25
x^2 + 5x + 5x + 25
x^3 + 10x + 25
The approximate measure of angle <em>acb </em>in right triangle <em>abc </em>in which the length of the hypotenuse, line segment ac is 25 cm is 53.1 degrees.
<h3>What is right angle triangle property?</h3>
In a right angle triangle, ratio of the adjacent side to the hypotenuse side is equal to the cosine angle between them.

Here, (a) is the adjacent side, (c) is the hypotenuse side and θ is the angle made between them.
The right triangle abc is given, in which,
- The length of the hypotenuse, line segment ac, in right triangle abc is 25 cm.
- The length of line segment bc is 15 cm.
According to the right angle triangle property,

Hence, the approximate measure of angle <em>acb </em>in right triangle <em>abc </em>in which the length of the hypotenuse, line segment ac is 25 cm is 53.1 degrees.
