Answer:

2. 5.25in

3. 3 in

4. 81.68 or 82

Step-by-step explanation:

The first two are basically multiplication and division. radius is half the diameter, and diameter is the whole of radius. the circumference is 3.14 or $\pi$ x diameter

so you need to add the radius (13) by itself (13+13) to get the diameter (or 13*2) then multiply by 3.14159. (26*3.14159 = 81.68) and if you need to round its 82.

twelve cookies are cut from a rectangle of dough measuring 12 inches by 16 inches. How many square inches of dough are left over

valentina_108 [34]

Given:

Here twelve cookies are cut from a rectangle of dough measuring 12 inches by 16 inches.

Required:

How many square inches of dough are left over

the radius of cooke is 2 inches because if we cut cookie s in this formation and we get 4 cookies in horizontal so there are 4 diameter of each cookie and the total of these 4 diameter is 16.

So now the measure of one cookie is

$\frac{16}{4}=4\text{ inches}$

now the diameter of one cookie is 4 inches so by this we can find the radius

$\begin{gathered} r=\frac{d}{2} \\ r=\frac{4}{2}=2\text{ inches} \\ \end{gathered}$

now first we find the area of dough which isin rectangle shape

area of rectangle is

$A_1=12*16=192\text{ inches}^2$

now we have to find the area of 12 cookies

area of cookies is

$A_2=12*\pi *r^2=12*\pi *4=48\pi\text{ inches}^2$

now after cut dough for 12 cookies and the left over dough is

Final answer:

$A=A_1-A_2=192-48\pi\text{ inches}^2$

A piggy bank contains nickels and dimes. There are 160 total coins valuing $10.50. Think about a system of equations that can be

Elodia [21]

$x + y = 160 \\ 0.05x + 0.1y = 10.50$
First, Substitute x + y = 160 into equation
x = 160 - y
$0.05(160 - y) + 0.1y = 10.50 \\ 8 - 0.05y + 0.1y = 10.50 \\ 0.05y = 2.50 \\ y = 50$
Substitute that into
$x + 50 = 160 \\ x = 110$

The answer is 110.

Hope this helps. - M
