Karrine hit 4 more home runs than half the number of home runs Lu hit. Together they hit 10 home runs. Let x represent the numbe
Andreas93 [3]

Answer:

The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6

Step-by-step explanation:

Let

x ----> represent the number of home runs Lu hit

y ---> represent the number of home runs Karrine hit

we know that

Together they hit 10 home runs

so

x+y=10 ----> equation A

Karrine hit 4 more home runs than half the number of home runs Lu hit

so

y=\frac{1}{2}x+4 ---> equation B

substitute equation B in equation A

x+\frac{1}{2}x+4=10

solve for x

\frac{3}{2}x=10-4

\frac{3}{2}x=6\\x=4

Find the value of y

y=\frac{1}{2}(4)+4=6

therefore

The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6

If the diameter of a circle changes from 18 cm to 6 cm, how will the circumference change?
omeli [17]
We know that 

the length of a circumference=2*pi*r
for D1=18 cm--------------> r1=9cm
L1=2pi*9-------> 18pi cm

for D2=6 cm-----------> r2=3 cm
L2=2pi*3-------> 6pi cm

L2/L1----------> (6pi)/(18pi)---->1/3

the answer is the option A) multiplies by 1/3

Find the area:......Brainliest........
pav-90 [236]

Answer:

Step-by-step explanation:

The average length of the weird trapezoidal shape on the left is

(2 m + 10 m)/2, or 6 m.  The width is 4 m, so the area is 24 m^2.

The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.

Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.

the volume of a rectangle prism with square bases is 5880 cubic inches. it has a height of 30 inches. find the side length of th
Delicious77 [7]
A prism with square bases is just a square prism.

The volume of a rectangular prism is equal to its width times its length times its height. Since the base is a square, we can just say it's equal to the base squared times the height. Let's set up a formula, plug and chug.

V = b^2h \\ 5880 = 30b^2 \\ 196 = b^2 \\  \sqrt{196}  = b \\ \boxed{14 = b}
