x (.60) + 60 (.15) = (x+60) .50
distribute
.60x +9 = .5x +30
subtract .5x from each side
.1x +9 = 30
subtract 9 from each side
.1x = 21
divide by .1
x = 210
You will need 210 gallons of 60% antifreeze
The formula of a circle is A = pi * r^2
The diameter is 16cm, half of a diameter is the radius.
16/2 = 8
The radius is 8cm
pi (8)^2 or 3.14 (8)^2 = 200.96
Closest answer will be 201 (option C)
Slope m=(y2-y1)/(x2-x1)=(10-4)/(4-2)=6/2=3
y = mx+b
y=3x+b
Take point (2,4),
4=3*2+b
4=6+b
b=-2
y=3x-2
Answer is D. <span>y = 3x − 2</span>
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal
(a)
= 
, substitute values
= 
( cross- multiply )
13.23AB = 111.132 ( divide both sides by 13.23 )
AB = 8.4
(b)
= 
, substitute values
= 
( cross- multiply )
6.3DF = 54.243 ( divide both sides by 6.3 )
DF = 8.61
7 goes into 7 once with no remainder
7 goes into 8 once with 1 remaining
7 goes into 16 twice with 2 remaining
