Each wheel on a car has a diameter of 22 inches.

murzikaleks [220]

Answer:

550 $\pi \\$

Step-by-step explanation:

So for each revolution of the wheel, it turns once. The length of the edge going around the circle is called the circumference. The circumference can be found by doing Pi * Diameter. So, plugging in the numbers:

$\pi \\$ * Diameter = Circumference

$\pi \\$ * 22 = Circumference = 22 $\pi \\$

Now, multiply this by 25, the amount of times the wheel goes around

22 $\pi \\$ * 25 revolutions = 550 $\pi \\$

Create a list of steps, in order, that will solve the following equation. 2(x+3/4)^2-5=123

IRISSAK [1]

Step-by-step explanation:

$2(x+\frac{3}{4})^2-5=123$

1. Add 5 to both sides.

$5+2(x+\frac{3}{4})^2-5=123+5$

$2(x+\frac{3}{4})^2=128$

2. Divide both sides by 2.

$\frac{2(x+\frac{3}{4})^2 }{2}=\frac{128}{2}$

$(x+\frac{3}{4} )^2=64$

3. Take the square root of both sides.

$\sqrt[]{(x+\frac{3}{4})^2 } =\sqrt[]{64}$

$x+\frac{3}{4}=8$

4. Subtract $\frac{3}{4}$ from both sides.

$-\frac{3}{4}+x+\frac{3}{4}=8-\frac{3}{4}$

$x=8-\frac{3}{4}$

$x=\frac{(8)(4)-3}{4}$

$x=\frac{32-3}{4}$

$x=\frac{29}{4}$

Julio is buying a carton of blueberries that has a mass of 100 grams. Is it reasonable to say that there are 250 blueberries in

velikii [3]

It is not reasonable to say that there are 250 blueberries in the carton because the average weight of the blueberry in the carton does not make sense. The average weight of the blueberry in the carton is 0.4 gram (=100/250) and the normal average weight of blueberry is 0.66 to 1.5 gram<span>. This gross calculation has not yet included the carton's mass.</span>
