which table shows a proportional relationship between x and y?
Find the area. Round to the nearest hundredths if necessary.
Answer:
12.25π + 77, or approximately 114.48.
Step-by-step explanation:
We can divide the figure into two semicircles (which equal to one circle) and a rectangle. We know that the diameter of the circles is 7, which means the radius is 3.5. Since all points on the circle are equidistant from the center point, we can subtract 18 - 3.5 - 3.5 = 11. Therefore, the dimensions of the rectangle are 11 x 7, which means the area of the rectangle is 77. The formula for the area of a circle is πr^2. There are two semicircles, which means the sum of them both will equal one circle, since they have the same radius. The sum of the areas of the two semicircles equate to 12.25π. The area of the figure is 12.25 + 77, or approximately 114.48.

42/6 = 7
Two students are reading a book. Keith reads 6 pages a day. Tameka reads 5 pages a day, but he starts sooner and has already read 15 pages. Write a system of equations to represent the situation, using d for days and p for pages. Will Keith and Tameka ever be on the same page on the same day? Explain.
Answer:
Keith p = 6d
Tameka p = 5d + 15
p=p so the following is also true:
6d = 5d + 15
let's do the same thing on both sides of the equation, subtract 5d
d = 15
after 15 days the will be on the same page
you could also say that Tameka is slowly catching up with a rate of 1 page per day
how do you find x in this? I need help asap!!
Answer:
Step-by-step explanation:
According to the theorem, the angle measuring 110 is one-half the measure of the arc it intercepts. That means that the major arc (this arc of which I'm speaking) measures 110 * 2 = 220.
Since the outside of a circle, regardless of how big or small the circle is, has a degree measure of 360, then x = 360 - 220 so
x = 140°
A ski lodge offers 3 weekend packages. One package provides 2 nights, 3 meals and 1 ski lesson for $310. The second package provides 2 nights, 5 meals and 2 ski lessons for $380. The third package provides 1 night and two meals for $150. Write and solve a system of equations to find the cost per night, per meal, and per lesson. show your work.
Answer:
The cost of 1 meal, 1 night and 1 ski lesson is $ 160.
Step-by-step explanation:
Let the nights be N , meals be M, ski lesson is S.
According to the question
2 N + 3 M + S = 310.....(1)
2 N + 5 M + 2 S = 380 ..... (2)
N + 2 M = 150 .....(3)
By solving (1), (2) and (3) we get
N = $ 110, M = $ 20, S = $ 30
So, the cost of 1 night, 1 meal, 1ski lesson is
1 x 110 + 1 x 20 + 1 x 30
= 110 + 20 + 30
= $ 160
What is the distance AB rounded to the nearest tenth?
Answer:
2.80
Step-by-step explanation:
Seeing that your scale is 1cm to 1unit to on both axes
If you add a point C then draw lines connecting them it should look like the diagram above
But the distance between A to C and B to C are both 2 cm
Giving you a right angled triangle
So using the Pythagoras theorem
AB²=AC²+BC²
AB²=2²+2²
AB²=4+4
AB²=8
Take square root of both sides
√AB²=√8
AB= 2.828
To the nearest tenth that will be
AB=2.80

i need the answer. (will give brainliest to first answer)
Answer:
[tex]\overline{PO}\cong \overline{SO}[/tex]
Step-by-step explanation:
SAS (Side-Angle-Side) is a proof of congruence for two triangles. It states that when two triangles share two sides and the angle between them, they are congruent. Therefore, if PO and SO are proven to be congruent, the two triangles in the figure will share two sides and the angle between them, thus being congruent.

draw and label a line a line segment a ray and an angle
Answer and Step-by-step explanation:
Everything is in the picture.
Lines are forever, so they have an arrow at each end.
Line segments have a dot at each end, so they don't go on forever.
A ray has a dot on one end and an arrow on the other, so one side goes on forever.
An angle can be acute, right, or obtuse.

Which of these inspires confidence increases purchases and speeds up the flow of investment and wages in the circular flow of the free market system
Question options:
A. antitrust laws B. the provision of public goods C. consumer-protection regulations D. fractional reserve banking.
Answer:
consumer-protection regulations
Explanation:
Consumer protection regulations are regulations that protect the public or general consumers against consumption of unsafe goods. These regulations hold manufacturers accountable for production of goods that may be harmful to consumers. The Consumer Protection Act of 1987 serves the purpose of penalizing erring manufacturers so that consumers are compensated for goods that brought damage to life or property. This therefore inspires great confidence in purchase of goods and investment as consumers are backed by the law.
if a car driver fills 10 1/2kg of cng and paid rs 1995 what is cost of 1kg of cng
answer quick pls
Given:
A car driver fills [tex]10\dfrac{1}{2}\text{ kg}[/tex] of CNG and paid Rs. 1995.
To find:
The cost of 1 kg of CNG.
Solution:
According to the given information,
The cost of [tex]10\dfrac{1}{2}\text{ kg}[/tex] of CNG = 1995 rupees
Using this information, we get
The cost of 1 kg of CNG = [tex]\dfrac{1995}{10\dfrac{1}{2}}[/tex] rupees
= [tex]\dfrac{1995}{\dfrac{20+1}{2}}[/tex] rupees
= [tex]\dfrac{1995}{\dfrac{21}{2}}[/tex] rupees
= [tex]1995\times \dfrac{2}{21}[/tex] rupees
= [tex]190[/tex] rupees
Therefore, the cost of 1 kg of CNG is 190 rupees.

Answer:
u need to provide data where is data
Please help?? I have an exam tomorrow
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
x² - 5xy + 6y² = x² - 3xy - 2xy + 6y²
= x(x - 3y) - 2y(x - 3y)
= (x - 3y)(x -2y)
x² - 4xy + 3y² = x² -xy - 3xy + 3y²
= x(x - y) - 3y(x - y)
= (x - y)(x - 3y)
x² - 3xy + 2y² = x² - xy - 2xy + 2y²
= x(x - y) - 2y(x - y)
= (x - y)(x - 2y)
Least common denominator = (x-y)(x - 2y)(x - 3y)
[tex]RHS = \frac{1*(x-y)}{(x-3y)(x-2y)*(x-y)}+\frac{a*(x-2y)}{(x-y)(x-3y)*(x-2y)}+\frac{1*(x-3y)}{(x-y)(x-2y)*(z-3y)}\\\\= \frac{x- y + ax - 2ay +x -3y}{(x-y)(x-2y)(x-3y)}\\\\= \frac{2x -4y +ax - 2ay}{ x^{3}-5x^{2}y+8xy^{2}-4y^{3}}[/tex]
Solve the system of equations. Write you answer as an ordered pair.
X - 3y = -13
3x + 7y = 25
Answer:
Step-by-step explanation:
x - 3y = -13
x = -13 + 3y
3 * (-13 + 3y) + 7y = 25
-39 + 9y + 7y = 25
16y = 64
y = 4
3x + 7 * 4 = 25
3x = -3
x = -1
Answer: (-1, 4)
solve the system of equations below
2x-12y=4
x+12y = 56
Write answer as an ordered pair
Answer:
x = 20
y = 3
Step-by-step explanation:
2x - 12y + x + 12y = 4 + 56
3x = 4 + 56
3x = 60
3x ÷ 3 = 60 ÷ 3
x = 20
x + 12y = 56
20 + 12y = 56
20 - 20 + 12y = 56 - 20
12y = 36
12y ÷ 12 = 36 ÷ 12
y = 3

find the angle r show ur work
Answer:
The measure of angle R is 112 degrees
Step-by-step explanation:
Using the given markings, we can see that we have an isosceles triangle
so RT is also 3x-2
Mathematically, the sum of the interior angles of a triangle is 180:
Thus;
9x + 4 + (3x-2) + (3x-2) = 180
9x + 3x +3x + 4-2-2 = 180
15x = 180
x = 180/15
x = 12
Recall; Angle R is 9x + 4
= 9(12) + 4 = 108 + 4 = 112
Rearrange so that there is no zero or negative exponent. 2m^0 n^-4
Answer:
2/n^4
Step-by-step explanation:
Anything to the zero power will become 1 so the m^0 will be 1 and that leaves just 2 in its place. Anything to a negative exponent is equal to its reciprocal so n^-1= 1/n^4. Then you multiple what remains, (2 x 1/n^4) to get the above answer.
Answer:
Step-by-step explanation:
2m^0*n^-4
=2*1*1/n^4
=2/n^4
Note:Any base that has it's power 0 is always considered as one .
If any base has negative exponent transfer that pase to the denominator then its power will be positive. For exanple:
4^-x

Solve for x: log(2x) + log3 = 5
Answer:2/3
Step-by-step explanation:
Answer:
X=50000/3 for x>0
Step-by-step explanation:
First get rid of log (3), toss it over exuation sign.
Then calculate the formula for double angle (sin 2x = sin²X + sin(X) x cos (X) + cos²X)
After you do that you should be able to divide everything with cos²X and get polynomial exuation which is solved by substitution method (you'll get tan and then switch it for lets say letter: t
