In bowling, knocking down all of the pins with the first ball of a frame is called a strike. roni is practicing bowling and gets a strike 2 times out of 10 attempts. her goal is to have a minimum strike rate of 50% . which inequality could roni use to determine the minimum number of consecutive strikes she needs to achieve her goal?

a. x+10/x+2 greater than or equal to 0.50

b. x+10x/x+2x greater than or equal to 0.50

c. x+2/x+10 greater than or equal to 0.50

d. x+2/x+10 greater than or equal to 0.50x

x+10x/x+2x greater than or equal to 0.50

i am unable to solve this problem

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
