Y=all the dog toys Lilly has.
z= toys that are red.
1/3(y)=z
1/3(y)=6
3x1/3(y)=6(3)
y=18
Lily will have 18 dog toys.
Answer:
14.5
Step-by-step explanation:
Quotient is just division.
8.7/0.6
Since we're dividing by a decimal, the number goes up.
I like to divide by decimals in an easier way than long division: Fractions.
8.7 = 8 & 7/10 = 87/10
0.6 = 6/10
<u>87</u> ÷ <u>6</u>
10 10
KCF = Keep Change Flip
<u>87</u> x <u>10</u> = <u>870</u>
10 6 60
870/60 = 29/2 = 14.5
Proof:
8.7 ÷ 14.5 = 0.6
9514 1404 393
Answer:
C. 12cm
Step-by-step explanation:
The equation for the perimeter of the rectangle is ...
P = 2(L+W)
34 = 2(n +m)
Solving for m, we get
m = 17 -n . . . . . . . divide by 2, subtract n
__
The Pythagorean theorem gives the relationship between the sides and the hypotenuse
m^2 +n^2 = (n+1)^2
(17 -n)^2 +n^2 = (n +1)^2 . . . . . . substitute for m
289 -34n +n^2 +n^2 = n^2 +2n +1 . . . . eliminate parentheses
n^2 -36n +288 = 0 . . . . . . . put in standard form
(n -12)(n -24) = 0 . . . . . . . . . factor
n = 12 . . . . . . . . . . n=24 is an extraneous solution here
The value of n is 12 cm.

Step-by-step explanation:
The constant multiple of liters in a jug to the weight in kilograms will be:
7 kg = 9.7 liters
1 liter = 7/9.7 kg
The number of kilograms a 48.5 liter jug of a sports drink would weigh will be:
= 7/9.7 × 48.5
= 35kg
