Answer:

$20.9

Step-by-step explanation:

First you find what 45% of the cost is:

0.45 x 38 = 17.1

Then, because this is a special/decrease in original price, you subtract:

38 - 17.1 = 20.9

$20.9

Hello there.

The bakers healthy baker can make 280 bagels in 10 hours. how many bagels can they bake in 15 hours? what was that rate per hour
Answer: First you should calculate the rate per hour.
280 / 10 = 28.
In one hour the baker can make 28 bagels.
Multiply the one hour amount by 15.
28 x 15 = 420.

In short, Your answer is the baker can make 420 bagels in 15 hours and it is 28 bagels per hour.

Hope This Helps You!

Find the angle between the vectors u=i-9j and v=8i+5j

Katyanochek1 [597]

Answer: $\cos^{-1} \left(\frac{-37}{\sqrt{7298}} \right) \approx 115.665^{\circ}$

Step-by-step explanation:

$u \cdot v=(1)(8)+(-9)(5)=-37\\\\|u|=\sqrt{1^{2}+(-9)^{2}}=\sqrt{82}\\\\|v|=\sqrt{8^{2}+5^{2}}=\sqrt{89}\\\\\cos \theta=\frac{-37}{\sqrt{82}\sqrt{89}}\\\\\theta=\cos^{-1} \left(\frac{-37}{\sqrt{82}\sqrt{89}} \right)\\\\\theta=\boxed{\cos^{-1} \left(\frac{-37}{\sqrt{7298}} \right) \approx 115.665^{\circ}}$

A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.

Tamiku [17]

You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
$V=540=\pi r^2*h= \pi r^2*15$
Then,
$r^2= \frac{540}{15 \pi }$
So, $r= \sqrt{\frac{540}{15 \pi }}$
radius is approximately 3.4cm
