Answer:
4 apples are $2.40
That means that 2 apples will be $1.20
And that one apple will be $0.60
$0.60*9= $5.40
She buys 5 more apples each week so she will buy 14 apples this week
$0.60*14= $8.40
Final answer : She will buy 14 apples next week for $8.40
Hope it helped! : )
Answer:
there would be a 44.4% chance of drawing all blue marbles.
Step-by-step explanation:
7+3+8=18 (total marbles) (8=the amount that are blue in the total)
8/18=44.4%
Answer:
-3
Step-by-step explanation:
firstly, -3/12 is not in the simpliest form so we have to simplified it:
-3/12 / 3 = -1/4, now we got:
= (-6*(-1/4)*-4*5) / 10
The upper part of the equation: (-6*(-1/4)*-4*5) can be simplified as:
((-6*-1*-4*5) / 4) / 10
= (-120/4)/10
= -30 / 10
= -3
Hope this help you :3
Answer:
Step-by-step explanation:
Recall the following Pythagorean Identity:
Let's solve the x equation for cos(t) and the y equation for sin(t).
After the solve we will plug into our above identity.
x=5cos(t)
Divide both sides by 5:
(x/5)=cos(t)
y=5sin(t)
Divide both sides by 5:
(y/5)=sin(t)
Now we are ready to plug into the identity:
Multiply both sides by 5^2:
This is a circle with center (0,0) and radius 5.
All I did to get that was compare our rectangular equation we found to
where (h,k) is the center and r is the radius of a circle.
