VashaNatasha [74]

$HEY THEIR!!$

Taking commen 2 in RHS
p = 2 (L+W )

Divide by 2 on both sides.
p/2 = L+W

Subtract W on both sides.
p/2 - W = L

or L = p/2- W

The table below shows the number of cameras made when an assembly line runs at a constant rate for a certain number of hours. Nu

jeka57 [31]

Computing the rate we get:

$\frac{300}{10}\frac{cameras}{\text{hour}}=30\frac{cameras}{\text{hour}}$

Then, when the assembly line runs at the same rate for 24 hours they will produce:

$24\text{hour}\cdot30\frac{cameras}{\text{hour}}=720\text{ cameras}$

Answer: Option C) 720.

What is the area of a cross section that is parallel to face CDHG ?

Dennis_Churaev [7]

Answer: Area of cross section that is parallel to face CDHG is 432 cm².

Step-by-step explanation:

Since we have given that

There is a cross section that is parallel to face CDHG.

So, Length of cross section would be 36 cm

Width of cross section would be 12 cm.

So, Area of cross section would be

$Length\times breadth\\\\=36\times 12\\\\=432\ cm^2$

Hence, Area of cross section that is parallel to face CDHG is 432 cm².

For the bake sale, Helen made cookies and brownies. The cookies sold for 95 cents, and the brownies sold for 60 cents. If she ba

Natalka [10]

Let us suppose that 'm' cookies and 'n' brownies were baked.

Since, Helen baked 31 items in total.

So, m+n = 31 (Equaion 1)

So, m = 31-n

Now, since cookies are sold for 95 cents, and the brownies sold for 60 cents.

Since, 1 $ = 100 cents

So, cookies are sold for $0.95, and the brownies sold for $0.60.

Helen sold the cookies and brownies at $23.85

So, 0.95m + 0.60n = 23.85 (Equaion 2)

Substituting the value of 'm' in equation 2, we get as

$0.95(31-n)+0.60n = 23.85$

29.45 - 0.95n +0.60n = 23.85

-0.35n = -5.6

So, n = 16

Since, m = 31-n

m = 31-16

m = 15

So, Helen sold 15 cookies and 16 brownies.

Transmutation is the process of changing the substance, tangible or not, from one form to the other. It means the transformation of one element in the periodic table into another by one or a series of nuclear decays or reactions. One type of transmutation is nuclear transmutation. Nuclear transmutation is the conversion of one chemical element or isotope into another though nuclear reactions or nuclear decay. Second type of transmutation is artificial transmutation. Artificial transmutation occur in machinery that uses nough energy to cause changes in the nuclear structure of the elements.
