A customer ordered a product online for $299 and was charged an additional $10 for shipping and handling. The customer received a rebate of $99 and a $25 credit for turning in an old cell phone. After a tax of 4% was applied, how much did the customer pay for the product?
Answers
Answer:
the amount paid by the customer for the product is $192.40
Step-by-step explanation:
The computation of the amount paid by the customer for the product is shown below:
= Total amount + Total amount × tax rate
= ($299 + $10 - $99 - $25) + ($299 + $10 - $99 - $25) × 0.04
= $185 + 185 × 0.04
= $185 + $7.4
= $192.40
Hence, the amount paid by the customer for the product is $192.40

If V2=200mL, C1=80%, C2=50%, what is V1?
Answers
Answer:
125 mL
Step-by-step explanation:
We are given:
V₁ = x mL
C₁ = 80%
V₂ = 200 mL
C₂ = 50%
Solving for x:
We know that:
V₁C₁ = V₂C₂ [Concentration formula]
replacing the values:
x(80) = (200)(50)
x = 125 mL [Dividing both sides by 80]

Subtract 175 from both sides which will turn 425 into 250
Divide 8 from 8x to the other side to turn 250 into 125/4
In the end, you get X is greater or equal to 125/4

Answer:
AC = 49
Step-by-step explanation:
Using the Altitude - on - Hypotenuse theorem
(leg of large Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)
BC² = DC × AC, substitute values
14² = 4 × x
196 = 4x ( divide both sides by 4 )
49 = x
Thus AC = x = 49
Step-by-step explanation:
pythogoream theorem.(hyp^2=opp^2+adj^2)
hyp=14 adg=4 opp=?
since we have to find opp
opp^2=hyp^2-adj^2
opp^2=14^2-4^2
196-16=180
[tex] \sqrt{180} [/tex]
BD= 13.41
(Q as theta)
sinQ= opp÷hyp
= 13.41÷14
Q=sin^-1(13.4÷14)
Q=73.33
cosQ=adj(AD)÷hyp(BC)
cos 73.33× 14 =adj
AD=4.01
Therefore, AC =AD +DC(4.01+4)
=8.01

ABCDE is a regular pentagon. Find each lettered angle measure.
Answers
Answer:
x° = 36°, y° = 36°, z° = 72°
Step-by-step explanation:
Each interior angle of a regular polygon is given by the following formula;
Interior angle = (n - 2)×180°/n
Where;
n = The number of sides on the polygon
For the pentagon, we have;
n = 5, therefore;
Interior angle = (5 - 2)×180°/5 = 108°
ΔDCA is an isosceles triangle, with the segments CD and CA being equal, therefore;
∠ADC = ∠DAC = x°, and ∠ACD = 108°
Therefore
x° = (180° - 108°)/2 = 36°
x° = 36°
∠BAC = 2·x° + y° = 108°
∴ y° = 108° - 2·x° = 108° - 2 × 36° = 36°
y° = 36°
ΔADE is an isosceles triangle, with segments AD and AE equal, therefore, the base angles are z° each
Therefore, in ΔADE, we have;
z° = (180° - 36°)/2 = 72°
z° = 72°
