The graph of a proportional relationship contains the point (4, 20). What is the constant of proportionality?
Enter your answer in the box.
9514 1404 393
Answer:
5
Step-by-step explanation:
A proportional relationship has the equation ...
y = kx . . . . . . where k is the constant of proportionality
Solving this equation for k, we get ...
k = y/x
Filling in the given values (x, y) = (4, 20) gives ...
k = 20/4
k = 5
The constant of proportionality is 5.
Answer:
The answer is 1/5 = 0.2

Answer:
[tex] \arc{PNM} = 222 [/tex]
Step-by-step explanation:
Central angle = measure of the arc it subtends
Therefore:
[tex] \arc{PN} = \arc{PM} = 138 [/tex]
A full circle = 360°
So,
[tex] \arc{PN} + \arc{PM} + \arc{NM} = 360 [/tex]
Plug in the values
[tex] 138 + 138 + \arc{NM} = 360 [/tex]
[tex] 276 + \arc{NM} = 360 [/tex]
[tex] \arc{NM} = 360 - 276 [/tex] (subtraction property of equality)
[tex] \arc{NM} = 84 [/tex]
[tex] \arc{PNM} = \arc{NM} + \arc{PN} [/tex]
Plug in the values
[tex] \arc{PNM} = 84 + 138 [/tex]
[tex] \arc{PNM} = 222 [/tex]
2 divided by negative 1/5
Answer: 10
you have to find a common denominator between two and five which is 10. therefore making the number 2 into the fraction 20/10 and finding the common denominator of 1/5 makes it now 2/10. now divide 20 by 2 which gets you 10. and dividing 10 by 10 gets you. therefore making the new fraction 10/1 which is equal to 10. :)

Determine the length of TZ.
Do not include spaces, units, or commas in your response.
Enter answer here. Do not include spaces or units.
Answer:
TZ = 24
Step-by-step explanation:
Similar Triangles
If two triangles are similar, then:
* All the corresponding side lengths are proportional by the same scale factor
* All the internal angles are congruent.
The image provided in the question has two similar triangles TYZ and TWX. We have completed the shape with a variable p =TZ, whose value will be determined by applying the first similarity condition above.
The ratio between the heights is 20:16, and the proportion between the bases is (6+p):p, thus:
[tex]\displaystyle \frac{6+p}{p}=\frac{20}{16}=\frac{5}{4}[/tex]
Cross-multiplying denominators:
4(6 + p) = 5p
24 + 4p = 5p
Solving for p:
p = 24
Then, TZ = 24
Total surface area of a cube is 1014cm^2. It's volume will be :

b) 2297 cm^3
c) 2179 cm^3
d) 2117 cm^3
plz answer...if you answer with explanation i will surely follow you and rate 5
Answer:
[tex]V=2197\ cm^3[/tex]
Step-by-step explanation:
Surface Area and Volume of a Cube
Given a cube of side length a, the surface area is:
[tex]A = 6a^2[/tex]
The volume is calculated as:
[tex]V=a^3[/tex]
It's given the surface area of a cube:
[tex]A=1014\ cm^2[/tex]
We can find the side length a by solving for a:
[tex]\displaystyle a=\sqrt{\frac{A}{6}}[/tex]
[tex]\displaystyle a=\sqrt{\frac{1014}{6}}[/tex]
[tex]\displaystyle a=\sqrt{169}[/tex]
a = 13 cm
Now compute the volume:
[tex]V=13^3[/tex]
[tex]\boxed{V=2197\ cm^3}[/tex]
Answer: a) 2197 cm^3

6 Cassius is purchasing flower baskets to
be placed on each table at a volunteer
appreciation lunch. Store A charges $19.25
per flower basket plus a $15.00 delivery fee.
Store B charges $17.50 per flower basket
plus a $30.00 delivery fee. Which inequality
can determine x, the maximum number of
flower baskets that can be ordered for the
total cost at Store A to be less than the total
cost from Store B?
A 19.25 + 15x > 17.5 + 30x
B 19.25 + 15x< 17.5 + 30x
C 19.25x + 15 > 17.5x + 30

A thrill at an amusement park travels 55 miles per hour.Round to the nearest hundredth,how many feet per second is this?
9514 1404 393
Answer:
80.67 fps
Step-by-step explanation:
1 mi/h = 22/15 ft/s
Multiplying this equation by 55, we get ...
55 mi/h = 1210/15 ft/s = 80 2/3 ft/s ≈ 80.67 ft/s

I need the answer for part b and c of number 23.
(x-8)2 – 7 = 25
Factored
Answer:
x = 8 ± 4√2
Step-by-step explanation:
(x - 8)² - 7 = 25
Add 7 to both sides.
(x - 8)² = 32
Take the square root for both sides.
x - 8 = ±√32
Add 8 to both sides.
x = 8 ±√32
Simplify √32
√32 = √16 · √2
√32 = ±4√2
x = 8 ± 4√2

Order the expressions from the least number of terms to the greatest number of TERMS.
Answer:
3x⁹, 2x - 5(3x²), 8x + 2x/3 + 6, x + 3 - y - 6
Step-by-step explanation:
3x⁹ has one term, so it comes first. 2x - 5(3x²) has two terms, so it comes next. 8x + 2x/3 + 6 has three terms and comes next. The last one is x + 3 - y - 6 because it has four terms.

The area of the square is
3x2 - 7x + 12. The area of the
triangle is x2 - 8x + 18. Find the
area of the shaded region.
Answer:
Area = 2x² + x - 6
Step-by-step explanation:
The area of the shaded region is the square area minus the triangle area:
[tex](3 {x}^{2} - 7x + 12) - ( {x}^{2} - 8x + 18) \\ {3x}^{2} - 7x + 12 - {x}^{2} + 8x - 18 \\ {2x}^{2} + x - 6[/tex]

Answer:
Adam: 52.26°
Step-by-step explanation:
Use Cosine Rule, [tex] Cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex], to find the angle of both players.
✔️Angle of Carlos:
Let the angle be C,
a = 50 ft
b = 40 ft
c = 24 ft
Plug in the values into the equation
[tex] Cos(C) = \frac{50^2 + 40^2 - 24^2}{2*50*40} [/tex]
[tex] Cos(C) = \frac{3,524}{4,000} [/tex]
[tex] C = Cos^{-1}(\frac{3,524}{4,000}) [/tex]
C = 28.24° (nearest hundredth)
✔️Angle of Adam:
Let the angle be C,
a = 30 ft
b = 22 ft
c = 24 ft
Plug in the values into the equation
[tex] Cos(C) = \frac{30^2 + 22^2 - 24^2}{2*30*22} [/tex]
[tex] Cos(C) = \frac{808}{1,320} [/tex]
[tex] C = Cos^{-1}(\frac{808}{1,320)} [/tex]
C = 52.26° (nearest hundredth)
A = {3,5,7,9}
B = {2, 4, 6, 8, 10)
C = {12, 14, 18, 20, 24}
D = {21, 26, 31, 36}

A 3 slope:3/2
B 3 slope -3/2
C -3 slope 3/2
D -3 slope -3/2
Answer:
C. y-intercept: -3
slope: 3/2
Step-by-step explanation:
✔️The line cuts across the y-axis at y = -3. Therefore the y-intercept = -3.
✔️Slope of the line using two points on the line, (0, -3) and (2, 0):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - (-3)}{2 - 0} = \frac{3}{2} [/tex]
Slope = ³/2

Find the missing endpoint if the midpoint is at (2,-5) and one endpoint is at (12,-5).
O (2,-5)
O(-8,-5)
O(10-8)
O (12,-5)
Answer:
The answer is (-8,-5)
Step-by-step explanation:
Since the midpoint is (2, -5), the 2 endpoints should be equidistant from each other. Since the endpoint that is given (12, -5), is 10 points to the right of the midpoint, the second midpoint should be 10 points to the left of it. 2-10=-8
Therefore, the other midpoint is (-8,-5)
