Answer:
The list price is of $650.
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: [tex]\frac{100-a}{100}[/tex]
List price: x
Discounts:
15%:
[tex]\frac{100-15}{100} = \frac{85}{100} = 0.85[/tex]
10%:
[tex]\frac{100-10}{100} = \frac{90}{100} = 0.9[/tex]
4%
[tex]\frac{100-4}{100} = \frac{96}{100} = 0.96[/tex]
This means that x is multiplied by 0.85, 0.9 and 0.96.
Net price of $477.36. What is the list price?
So
[tex]0.85*0.9*0.96x = 477.36[/tex]
[tex]x = \frac{477.36}{0.85*0.9*0.96}[/tex]
[tex]x = 650[/tex]
The list price is of $650.

Use the Law of Cosines to determine the indicated side x. (Assume a = b = 20. Round your answer to one decimal place.)
x =
Answer:
37.6
Step-by-step explanation:
x² = a² + b² - 2ab cos 140°
x² = 20² + 20² - 2(20)(20)(-0.766)
x² = 400 + 400 - 800(-0,766)
x² = 800 - (-612.835)
x² = 800 + 612.835
x² = 1412.835
x =√1412.835 = 37.6
The value of x is 37.6.
We have,
The Law of Cosines states:
[tex]c^2 = a^2 + b^2 - 2ab * cos(C)[/tex]
Where c represents the length of the side opposite angle C, and a and b represent the lengths of the other two sides.
The angle C is the angle opposite side c.
Now,
We can apply the law of cosines in the given figure.
x² = a² + b² - 2ab Cos 140
Now,
a = b = 20
So,
x² = a² + b² - 2ab Cos 140
x² = 20² + 20² - 2 x 20 x 20 x Cos 140
x² = 400 + 400 - 800 Cos 140
x² = 800 - 800 x - 0.77
x² = 800 + 616
x² = 1416
x = 37.63
x = 37.6
Thus,
The value of x is 37.6.

I need to solve the equation to get x, can someone please help:(
what does this mean when a rhombus is split into 2 triangles ; what's the formula to find the value of x? also it's about polygons
Answer/Step-by-step explanation:
The rhombus when split into two triangles will give us two equilateral triangles that are congruent to each other.
Therefore:
The two bases of both triangles will have equal angle measures of 4x + 5 each and a third angle measure of 8x - 6.
✅Formula to find the value of x:
(8x - 6) + 2(4x + 5) = 180° (sum of triangle)
8x - 6 + 8x + 10 = 180
8x + 8x - 6 + 10 = 180
16x + 4 = 180
16x + 4 - 4 = 180 - 4
16x = 176
16x/16 = 176/16
x = 11

Answer:
True
Step-by-step explanation:
Congruence is a relationship that exist between majorly two shapes which compares their given sides and angles to determine if they are similar.
From the given diagram,
AE ≅ DE (congruence relations)
BE ≅ CE (congruence relations)
Also,
<AEB ≅ DEC (vertically opposite angles)
Thus, it can be observed that;
ΔABE ≅ ΔDCE by Side-Angle-Side (SAS) congruent relationship.
So that the SAS congruence relationship is true.

Answer:
23 1/9 sq. inches
Step-by-step explanation:
Start by making 4 1/3 into 13/3 and 5 1/3 into 16/3. You can find area by multiplying one side by another, so we multiply 13/3 and 16/3. We can multiply the numerators (Top) of the fractions and put them over the denominators (Bottom) of the fractions multiplied for our result. 13 * 16 is 208 and 3 * 3 is equal to 9. The simplified form is 23 1/9.
The scatterplot above shows the number of hits and the
number of times at bat by each of 20 players on a major
league baseball team. The line of best fit for the data is
also shown.
For the player with 450 times at bat, the actual
number of hits the player had is approximately how
many fewer than the number of hits predicted by the
line of best fit?
A) 10
B) 20
C) 30
D) 10
The actual number of hits the player had is approximately 10 fewer than the number of hits predicted by the line of best fit
How to interpret the scatter plot?From the complete question, we have the following highlight:
The blue line is the predicted number of hitsThe red line is the actual number of hits.From the graph, we have the following readings at x = 450
Actual readings y = 123 Predicted readings y = 113Calculate the difference
d = 123 - 113
Evaluate the difference
d = 10
Hence, the actual number of hits the player had is approximately 10 fewer than the number of hits predicted by the line of best fit

The average price of a two-bedroom apartment in the uptown area of a prominent American city during the real estate boom from 1994 to 2004 can be approximated by p(t) = 0.12e0.10t million dollars (0 ≤ t ≤ 10) where t is time in years (t = 0 represents 1994). What was the average price of a two-bedroom apartment in this uptown area in 2002, and how fast was the price increasing? (Round your answers to two significant digits.)
Answer:
Step-by-step explanation:
Average price of a two bedroom apartment can be approximated by the equation,
p(t) = [tex]0.12e^{0.10t}[/tex]
Here, t represents the duration from year 1994.
Duration from year 1994 to year 2004 = 10 years
p(10) = [tex]0.12e^{0.10\times 10}[/tex]
= 0.12e
= 0.3262
≈ 0.33 million
Cost of the apartment in 2004 was 0.33 million.
Let the equation to calculate the rate of increase in the price is,
p(t) = [tex]0.12(1+\frac{r}{100})^t[/tex]
Cost of the apartment after 10 years = 0.33
0.33 = [tex]0.12(1+\frac{r}{100})^{10}[/tex]
[tex]\frac{0.33}{0.12}=(1+\frac{r}{100})^{10}[/tex]
2.75 = [tex](1+\frac{r}{100})^{10}[/tex]
[tex](1+\frac{r}{100})=(2.75)^{0.10}[/tex]
1 + [tex]\frac{r}{100}=1.106[/tex]
[tex]\frac{r}{100}=0.106[/tex]
r = 10.6%
Therefore, price of the apartment is increasing with 10.6%
