ankoles [38]3 years ago
3 0

Answer:

  1. 3.5(1.6 + 4.6 - 8.5) - 9.75
  2. = 3.5(-2.3) - 9.75
  3. = -8.05 - 9.75
  4. = -17.8

Step-by-step explanation:

  1. 1.6 + 4.6 - 8.5 = -2.3
  2. 3.5(-2.3) = 3.5 × -2.3 = -8.05
  3. -8.05 - 9.75 = -17.8

I hope this helps!

Which expression can be used to find the retail price of an item that was bought at wholesale for $112 and sold at a 40% markup?
umka2103 [35]
D. $112 + 0.40($112) is the answer

The wholesale price = $112
Markup percentage = 40% or 0.40
So, the expression that will give the retail price of the item = 112 + 0.40 (112)
Retail price = purchase/wholesale price plus markup

On a coordinate plane, a shape is plotted with vertices of (3, 1), (0, 4), (3, 7), and (6, 4). what is the area of the shape if
QveST [7]
Let
<span>A (3, 1)
B (0, 4)
C(3, 7)
D (6, 4)

step 1
find the distance AB
d=</span>√[(y2-y1)²+(x2-x1)²]------> dAB=√[(4-1)²+(0-3)²]-----> dAB=√18 cm

step 2
find the distance CD
d=√[(y2-y1)²+(x2-x1)²]------> dCD=√[(4-7)²+(6-3)²]-----> dCD=√18 cm

step 3
find the distance AD
d=√[(y2-y1)²+(x2-x1)²]------> dAD=√[(4-1)²+(6-3)²]-----> dAD=√18 cm

step 4
find the distance BC
d=√[(y2-y1)²+(x2-x1)²]------> dBC=√[(7-4)²+(3-0)²]-----> dBC=√18 cm

step 5
find slope AB and CD
m=(y2-y1)/(x2-x1)
mAB=-1
mCD=-1
AB and CD are parallel and AB=CD

step 6
find slope AD and BC
m=(y2-y1)/(x2-x1)
mAD=1
mBC=1
AD and BC are parallel and AD=BC
and 
AB and AD are perpendicular 
BC and CD are perpendicular

therefore
the shape is a square wit length side √18 cm

area of a square=b²
b is the length side of a square
area of a square=(√18)²------> 18 cm²

the answer is
18 cm²

see the attached figure
