2) josh can invite 14 friends. Each will get 3 granola bars and 4 fruit drinks

3) 4(7+3)

Step-by-step explanation:

42 = 3x2x7

56=2x2x2x7

common = 2x7 or 14

42/14 is 3

56/14 is 4

josh can invite 14 friends. Each will get 3 granola bars and 4 fruit drinks

28 = 2x2x7

12=2x2x3

common = 2x2=4

Merry Christmas!

Janna has three flat plates easy the same size. She stores them in an L shaped drawer as shown so that they fit snuggly inside w

Phantasy [73]

Answer:

258 square centimeters

Step-by-step explanation:

Consider the image attached below.

We can see that the length of each side of L shape is 40 cm and in 2 plates fit in between.

We need to find the are which is not covered by the plates. Let us calculate the area of L shape first.

We can see that it is a square with one fourth of its area missing. So the area of square with side length 40 cm is,

$A_1= 40 \times 40 = 1600 cm^2$ , where ' $A_1$ ' is the area of square.

Now, one fourth of the area is not there in the L shape, so one-fourth of $1600cm^2$ is,

$\frac{1600}{4}= 400 cm^2$

Therefore, the area of L shape drawer is,

$1600-400=1200 cm^2$

Now, we can see that the diameter of each circular plate is, 20 cm. So the radius of circular plate is 10 cm. Let $A_2$ be the area of each circular plate, so,

$A_2= \pi (10)^2=100\pi cm^2$

There are three plates so the total area is,

$A_3= 3\times 100 \pi = 300 \pi cm^2$

$A_3= 300\times 3.14 = 942 cm^2$

Hence, the area not covered by the plates is,

= $1200-942= 258 cm^2$

So, the area not covered by three flat plates is 258 square centimeters.

8x13=104 8x5=40

104+40=144✅

Under what circumstances does the system of equations Qx+Ry=S and Y=Tx+S have infinitely many solutions?

Anettt [7]

From these -Tx+y=S. If -T=Q/R, then y=-Qx/R+S, so Ry=-Qx+RS, Qx+Ry=RS=S.
If R is not equal to 1, or S is non-zero, the equations are inconsistent, so there would be no solutions.
If R=1 there are an infinite number of solutions given by Qx+y=S, or y=S-Qx or y=S+Tx.
If S=0, Qx+Ry=0 or y=-Qx/R or y=Tx.
