A small box weighs 1 25 pounds. A large box weighs 3 1/3 time as much as the small box. how much does the large box weigh?

Answers

Answer 1

Answer:

Answer:

416.7pounds

Step-by-step explanation:

Given parameters:

Weight of the small box = 125pounds

Unknown:

Weight of the larger box = ?

Solution:

The large box weighs $3(1)/(3)$ times as the small box:

So;

= 125pounds x $(10)/(3)$

= 416.7pounds

Answer:

c. ¾

Step-by-step explanation:

By adding fractions, you must follow the following steps:

1. Make sure the numbers of the denominators are equal.

2. Add the numerators and put this number over the denominator.

3. Simplify.

Since the number of the denominators are different. We must multiply and divide one fraction for a number such that the denominators stand equal. For instance, we can multiply and divide fraction 1/4 by number 2 as follows:

$(1)/(4)=(1 * 2)/(4 * 2)= (2)/(8)$

So the expression can be written as follows:

$(4)/(8)+(2)/(8)=(6)/(8) \n \n But \ (6)/(8) \ can \ be \ written \ as: \n \n (3 * 2)/(4 * 2) = \boxed{(3)/(4)}$

The equation for the volume of a cylinder is v=πr²h the positive value of r, in terms of h and V, is

Answers

The positive value of r is $\sqrt{(v)/(\pi h) }$

What is the volume of cylinder ?

The volume of cylinder is basically the density of the cylinder which amount it can carry.

The volume of cylinder is the product of the area of the circular base and height.

If, r be the base radius and h be the height of a cylinder, then the volume of cylinder(v) = $\pi r^(2) h$ cubic unit

How to find the value of r from volume of cylinder formula ?

The volume of cylinder(v) = $\pi r^(2) h$ ,where r=radius, h=height, v=volume of cylinder

∴ $v=\pi r^(2) h$

⇒ $r^(2) =(v)/(\pi h)$

⇒ $r=$ ± $\sqrt{(v)/(\pi h) }$

According to the problem, Only the positive value of r is required.

So, $r=\sqrt{(v)/(\pi h) }$

Melinda bought 6 bowls for $13.20. what was the unit rate in dollars

Answers

To find the unit rate we will divide the amount of dollars ($13.20) by the amount of bowls (6). Then we will check our work. lets do it:-

13.20 ÷ 6 = 2.20
$2.20 per bowl

CHECK OUR WORK:-

2.20 × 6 = 13.20
we were RIGHT!!

So, the unit rate in dollars for, Melinda bought 6 bowls for $13.20 is, $2.20 per bowl.

Hope I helped ya!! xD

Just put this , 13.20/6 which is 2.20 so thats 2.20$ a bowl.
also you could , 2.20*6=13.20 , thats still 13.20 (2.20)

all together this means the unit rate in dollar is 2.20 for bowl , per bowl. for Melinda because she bought them for 13.20

i hope this helps.
