White chocolates
$4.50 x (2/3)
= $9/3
= $3
Gummy bears
$2.40 x (1/2)
= $2.40/2
= $1.20
Dark chocolates
$6.00 x (1 1/4)
= $6.00 6/4
= $7.50
$3.00 + $1.20 + $7.50
=$11.70
Therefore, Victor spent $11.70 on candy for the party.

Parabola
4P(y-k)=(x-h)^2
where (h,k) is vertex
P is distance from vertex to focus which is also equalt to distance from vertex to directix
we plot those points and see it opens up (don't cross directix)
P is positive
from 4 to 3 is a distace of 1
1/2=1/2
P=1/2
3+1/2=3.5
the vertex is (-1,3.5)
4(1/2)(y-3.5)=(x+1)^2
2(y-3.5)=(x+1)^2
put in vertex form (solve for y)
divide both sides by 2
y-3.5=(1/2)(x+1)^2
add 3.5
y=
Answer:
The answer is E: I, II, and III
Step-by-step explanation:
The three major features of a well designed experiment are:
1. Replication: If an experiment cannot be replicated, then it is not a well-designed experiment. Replication is one of the major characteristics of a well designed experiment
2. Control: A well designed experiment must have a control. Control, in an experiment, can be referred to as the steps taken to curb the impact of extraneous variables
3. Randomization: Subjects are expected to be randomly assigned to different groups.
Answer:
10x^2+x-2
Step-by-step explanation:
(2x+1)(5x-2)
10x^2+5x-4x-2
10x^2+x-2
Answer:
Now since we have the same units for the scale model and the real one we can find the scale factor like this:
And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
Step-by-step explanation:
For this problem we know that the scale model had a widthof 6 inches. And the actual model has a width of 4ft. First we need to convert the 4ft to inches and we got:
Now since we have the same units for the scale model and the real one we can find the scale factor like this:
And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
