Question = 0.75a + 10b + a - 2b

First collect like terms 0.75a + a + 10b - 2b

= 1.75a + 8b

what are like terms : they are terms with the same variable and the same exponent. example: 9xy and -6xy etc.......

A cylinder shaped juice pitcher has a diameter of 12 cm and a height of 25 cm. What volume of juice does the pitcher contain whe

Andreas93 [3]

Answer:

706.50 cubic cm.

Step-by-step explanation:

Given that a cylinder shaped juice pitcher has a diameter of 12 cm and a height of 25 cm.

We are to find out the t volume of juice does the pitcher contain when it is 25% full. 3.14 is to be used for pi.

Volume of the cylinder = $\pi r^2 h\\ \\=3.14 *6^2*25\\=2826$

When it is 25% full the volume would be 1/4 of the full volume

= $\frac{2826}{4} =706.50$ cubic cm

So volume when 25% full is

706.50 cubic cm.

The pendulum of an antique clock has been damaged and needs to be replaced.If the original pendulum completed one swing every 1.

baherus [9]

Answer:

The length of pendulum is 55.853cm

Step-by-step explanation:

We are given

the original pendulum completed one swing every 1.5 seconds

so, T=1.5 sec

now, we can use time period formula

$T=2\pi \sqrt{\frac{l}{g} }$

l is the length of pendulum

g is acceleration due to gravity

$g=9.8m/s^2$

now, we can plug values

and then we can solve for l

$1.5=2\pi \sqrt{\frac{l}{9.8} }$

$\frac{l}{9.8}=0.05699$

$l=0.55853m$

In cm

$l=55.853cm$
