Answer:
Each of them spent $9.35 on meal.
Step-by-step explanation:
Jacob and his three friends ordered an individual pizza and a drink for $6.19.
Total cost of pizza and drink = 6.19 × 4
= $24.76
They also ordered bread sticks for $4.25
Tax on the bill was = $2.39
Tip amount was = $1.50×4 = $6.0
So the total billed amount will be = 24.76 + 4.25 + 2.39 + 6
= $37.4
Since there were four persons including Jacob.
Therefore, each person spend on meal =
= $9.35
Answer:
B. y=1/3x+4
Step-by-step explanation:
Hi there!
We are given the line PQ and we want to find the line that is perpendicular to it
Perpendicular lines have slopes that are negative and reciprocal. When they are multiplied together, the result is -1
So first, let's find the slope of the line PQ
The point P is given as (-8, 7) and the point Q is given as (-4, -5)
The formula for the slope calculated from two points is where (
) and (
,
) are points
We have the needed information for the slope, but let's label the values of the points to avoid any confusion
x1=-8
y1=7
x2=-4
y2=-5
Now substitute into the formula (m is the slope, and remember: the formula contains SUBTRACTION):
m=
simplify
m=
add
m=-12/4
divide
m=-3
So the slope of the line PQ is -3
As said above, perpendicular lines have slopes that have a product of -1
So to find the slope of the line perpendicular to PQ, use this formula:
-3m=-1
divide both sides by -3
m=1/3
The only line that has a slope of 1/3 is B (y=1/3x+4), so B is the answer.
Hope this helps!
Answer:
12
Step-by-step explanation:
8·15·h=1440
120·h=1440
=
(Divide both sides by 120)
h=12
<em><u>h stands for height</u></em>
