Answer:
Answer is D
Step-by-step explanation:
because its sideways its x = y^2
and because its facing right its positive.
There would be 25 girls. You would turn it into a fraction and times both by 5 to get 20/25. 5/4=1.25 and 25/20=1.25 in case you need to check your work
Answer:
.26
Step-by-step explanation:
P=(at least one high chair)
= 1−P(none of 10 with high chair)
= 1−(0.97)
10
≈ 1−0.7374
≈ 0.2626
Rounded to the nearest hundred is .26
So, first lets define our variables:
let x = the number of dimes
let y = the number of nickels
so our first equation would be x+y = 16
Since dimes are 10 cents and nickels are 5 cents the next equation would be as follows:
.10x+.05y = 1.35
now change the first equation so y = -x+16
now substitute:
.10x+.05(-x+16) = 1.35
then multiply so you get .10x+-.05x+0.8=1.35
combine like terms and you get .05x+0.8 = 1.35
then subtract 0.8 from both sides and you get .05x = 0.55 then subtract
and you get x = 11 then substitute 11 for where x should be and you should get y = 5
So, you have 11 dimes and 5 nickels
slope = difference in y / difference in x
slope = 12 -11 / 2 -6
slope = 1 / -4
slope = -1 / 4 or
-.25
