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.

Jamie, John, and Jake are on the prom committee. They are responsible for blowing up the balloons for prom night. John can blowu
san4es73 [151]
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.

Find a value for b so that the polynomial x^2+ bx + 25 factors to (x + 5)^2.
Marta_Voda [28]

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 length of the hypotenuse, line segment ac, in right triangle abc is 25 cm. the length of line segment bc is 15 cm. which is
Georgia [21]

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.

\cos\theta=\dfrac{b}{c}

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,

\cos(acb)=\dfrac{bc}{ac}\\\cos(acb)=\dfrac{15}{25}\\\angle acb=\cos^{-1}(0.6)\\\angle acb=53.1^o

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.
