Sally has 2 cats and each cat eats 1/4 of a tin of cat food each day.
Mashutka [201]

If one cat eats 1/4 of a tin per day then two cats eat 1/2 of a tin per day.

We have 9 tins so if each day cats eat 1/2 we have to divide 9 with 1/2 and we get 18 which is for how many days she can feed the cats until she runs out of food.

Hope this helps.

What is the measure of each of the arc?
madam [21]
A=138° B=180° C=180° D=138°
This is because angle QRS and QTS would equal 180° Bc they are supplementary. So 180-42=138. And since they are supplementary and vertical angles, angle ST would also be 42° and QT would also be 138° because angle RS is 138°

20 points (looking for the reasoning) Jayden and Sheridan both tried to find the missing side of the right triangle.
barxatty [35]

Answer:

Step-by-step explanation:The problem is very hard to read.  When using exponents, please add the "^" in front.  For example, is 132 actually 132, or is it 13^2?  The right triangle is not shown, so we really don't know which is the hypotenuse. Also be carefull with spacing.  Making some assumptions, here is how the answer might look:

Both have the correct formula:  a^2 + b^2 = c^2, assuming c is the hypotenuse.

If c is the hypotenuse, then the expression should be:

7^2 + b^2 = 13^2, or

49 + b^2 = 169

I like Sheridan's answer.  So let's continue:

49 + b^2 = 169

b^2 = 169-49

b^2 = 120

b = 10.954 . . .

Yep, I'm on Sheridan's side.  [That is, unless 72 is 72 and not 7^2, etc.]

The volume of this cylinder is 1751 cubic units. What is the volume of a cone that has the same base area and the sam height
siniylev [52]

Answer:

V_2 = 583.67

Step-by-step explanation:

Given

Represent the volume of the cylinder with V1 and the cone with V2.

So:

V_1 = 1751

Required

Find V2

The volume of a cylinder is:

V_1 = \pi r^2h

Because the cone and the cylinder have the same base area and height, the volume of the cone is:

V_2 = \frac{1}{3}\pi r^2h

Substitute V_1 for \pi r^2h.

V_2 = \frac{1}{3}\pi r^2h

V_2 = \frac{1}{3}V_1

Substitute 1751 for V1

V_2 = \frac{1}{3} * 1751

V_2 = \frac{1* 1751}{3}

V_2 = \frac{1751}{3}

V_2 = 583.67

<em>The volume of the cone is 583.67 cubic units</em>
