If triangle ABC is similar to triangle PQR, find the value of x and y.
Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.
[tex]\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}[/tex]
[tex]\frac{6}{x}= \frac{4}{y}= \frac{8}{12}[/tex]
[tex]\frac{6}{x}= \frac{8}{12}[/tex]
x = [tex]\frac{12\times 6}{8}[/tex]
x = 9
Similarly, [tex]\frac{4}{y}= \frac{8}{12}[/tex]
y = [tex]\frac{12\times 4}{8}[/tex]
y = 6

Here is the histogram of a data distribution. All class widths are 1.
What is the median of this distribution?
O A. 4
O B. 3
O C. 6
D. 5
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Statistics of a Categorised data.
We know that medium is the middle most point of any observation table or a Histogram displayed,
Hence we can clearly see here that, observation - 4 on the x-axis is the middle most entry of the Histogram, around which all other entries are equal.
===> Hence, option A.) 4 is correct answer.

5% of 90 m =
m
25% of 88 kg =
kg
75% of 264 =
Answer:
1) 5% of 90m= 4.5m
2)25% of 88kg = 22kg
3) 75% of 264= 198
Step-by-step explanation:
1) 90m = 100% (divide by 10)
9 = 10% (divide by 2)
4.5 = 5%
2) 88kg = 100% (keep on dividing by 2)
44kg = 50%
22kg=25%
3) 264 = 100%
132 = 50%
66 = 25% (add)
198=75%

5+4+8+4+3= 24
The probability she will pick and yellow and orange ( add those numbers together)
Yellow + orange = Numerator
5+4=9
How you answer should be lay out :
[tex]\frac{Orange+ yellow sweets}{Total amount of sweets}[/tex]
Answer:

Your restaurant bill comes to $46.27. Estimate a 10% tip.
If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.
What is percentage?Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.
How to calculate percentage?We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.
Tip=Bill*10/100
=46.27*10/100
=4627*10/100*100
=46270/10000
=$4.627
Hence if the bill of the restaurant is $46.27 then tip will be $4.627.

Answer:
A. Distance KL = 7.36 m
B. Height ML = 4.25 m
C. The maximum height is 6.96 m
Step-by-step explanation:
A. Determination of distance KL
Hypothenus = KM = 8.5 m
Angle θ = 30°
Adjacent = KL =?
Cos θ = Adjacent / Hypothenus
Cos 30 = KL / 8.5
0.866 = KL / 8.5
Cross multiply
KL = 0.866 × 8.5
KL = 7.36 m
Thus, the distance is 7.36 m
B. Determination of height (ML)
Hypothenus = KM = 8.5 m
Angle θ = 30°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 30 = ML /8.5
0.5 = ML / 8.5
Cross multiply
ML = 0.5 × 8.5
ML = 4.25 m
Thus, the height is 4.25 m
C. Determination of the maximum height.
Hypothenus = KM = 8.5 m
Angle θ = 55°
Opposite = ML =?
Sine θ = Opposite /Hypothenus
Sine 55 = ML /8.5
0.8192 = ML / 8.5
Cross multiply
ML = 0.8192 × 8.5
ML = 6.96 m
Thus, the maximum height is 6.96 m

A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be cx dollars per year, while her rent will be 4c/( x + 1) dollars per year, where c is a constant taking various situational factors into account. How far should she live from work to minimize her combined expenses for rent and transportation? Use the methods outlined in this section to find the minimum.
Answer:
the woman has to live 1 mile from work to minimize the expenses
Step-by-step explanation:
Given the data in the question;
the distance within 9 miles ⇒ 0 < x > 9
Total costs Q = cx + 4c/( x + 1)
costs should be minimum ⇒ dQ/dx = 0
⇒ d/dx [ cx + 4c/( x + 1) ] = 0
⇒ ( x + 1)² = 4
take square root of both side
√[ ( x + 1)² ] = √4
x + 1 = 2
x = 2 - 1
x = 1
Therefore, the woman has to live 1 mile from work to minimize the expenses

Find the area of the figure.
7 cm
8 cm
11 cm
The area is
square centimeters.
Answer:
let's divide the figure in rectangle and triangle.
first we should find the area of triangle.
area of triangle =1/2×base×height
area of triangle=1/2×11cm×7cm
area of triangle=38.5cm²
area of rectangle =length ×width
area of rectangle =11cm×8cm
area of rectangle =88cm²
area of the figure=38.5cm²+88cm²
area of the figure=126.5cm²
The graph shows the relationship between the distance a car is driven and the number of gallons of gasoline used. Identify the value in d in the point (1, d). What does that point represent?
A. d=25; the unit rate is 25 miles per gallon
B. d=25; the unit rate is 25 gallons per mile
C. d=50; the unit rate is 50 miles per gallon
D. d=50; the unit rate is 50 gallons per mile
Answer:
A. d = 25; the unit rate is 25 miles per gallon
Step-by-step explanation:
The point (1, d) on the graph represents (x, y), where,
x = gasoline used = 1 gallon
y = distance = d = 25 miles
That is, (1, d) represents when x = 1, y = 25.
Thus, (1, 25) is the unit rate which is 25miles per gallon.
Simplify fully 4a sqaured +8a +2 I-a squared +9a -3
Answer:
The simplified expression is: [tex]3a^2 + 17a - 1[/tex]
Step-by-step explanation:
We are given the following expression:
[tex]4a^2 + 8a + 2 - a^2 + 9a - 3[/tex]
We can fully simplify the expression by combining the like terms. So
[tex]4a^2 + 8a + 2 - a^2 + 9a - 3 = 4a^2 - a^2 + 8a + 9a + 2 - 3 = 3a^2 + 17a - 1[/tex]
The simplified expression is: [tex]3a^2 + 17a - 1[/tex]
