Answer:
36 cm
Step-by-step explanation:
The area of a square is given by
A = s^2
81 = s^2
Take the square root of each side
9 =s
We want the perimeter
P =4s
P= 4*9
P = 36
When converting 27 miles to kilometers, the final answer is:
a. 43.443 km
b. 142, 560 km
c. 16.7806091 km
d. 47.520 km
Answer: a. 43.443 km
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
27 miles to kilometers
Since 1 mile = 1.609344 km
We simply have to multiply the number of miles by 1.609344.
Mathematically speaking:
27 x 1.609344 = 43.4522 km
The closest result is option a. 43.443 km.

Write the explicit rule,
Answer:
[tex]a_{n}[/tex] = 20n + 12
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 52 - 32 = 72 - 52 = 92 - 72 = 20
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 32 and d = 20, thus
[tex]a_{n}[/tex] = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12
Circumference and area of a circle (picture provided)
Answer:
B
Step-by-step explanation:
The formulas we need are below:
C=dπ
A=r²π
d=2r
Plug in the values.
d=12
C=12π
A=36π
C=12(3.14)=37.68
A=36(3.14)=113.04
B matches
Solve for the variable "d" in the following equation.
[tex]F=\frac{Gm_1 m_2}{d^2}[/tex]
[tex]F = \frac{Gm_{1}m_{2} }{d^{2} }[/tex]
F x [tex]d^{2}[/tex] = G[tex]m_{1}m_{2}[/tex]
[tex]d^{2}[/tex] = [tex]\frac{Gm_{1}m_{2}}{F}[/tex]
d = ±[tex]\sqrt{\frac{Gm_{1}m_{2}}{F} }[/tex]
Since "m1" and "m2" represent different masses, we can change them to different letters. This will make it easier to solve.
m1 = m
m2 = n
F = G*m1*m2/d^2 → F = Gmn/d^2
Steps to solve for d:
F = Gmn/d^2
~Multiply d^2 to both sides
d^2 * F = d^2 * Gmn/d^2
~Simplify
d^2 * F = Gmn
~Divide F to both sides
d^2*F/F= Gmn/F
~Simplify
d^2 = Gmn/F
~Take the square root of both sides
√d^2 = ±√Gmn/F
~Simplify
d = ±√Gmn/F
Since we are done solving for d, we can input "m1" and "m2" to replace "m" and "n".
d = ±√Gmn/F → d = ±√G*m1*m2/F
Therefore, the answer is [ d = ±√G*m1*m2/F ]
Best of Luck!
solve for s

S =
Answer:
s = -3
Step-by-step explanation:
13s - 8s - -19 = 4
Combine like terms
5s +19 = 4
Subtract 19 from each side
5s +19-19 = 4-19
5s = -15
Divide by 5
5s/5 = -15/5
s = -3
Answer:
-3
Step-by-step explanation:
1) combine like terms:
5s--19=4
5s+19=4
subtract 19 from both sides:
5s=-15
s=-3

FOR A TEST, PLEASE HELP Two angles are supplementary if their sum is 180°. The larger angle measures three degrees more than twice the measure of a smaller angle. If x represents the measure of the smaller angle and these two angles are supplementary, find the measure of each angle. The smaller angle measures ? degrees. The larger angle measures ? degrees.
Step-by-step explanation:
I think writing the given out helps a bit.
x = small angle
2x+3 = large angle <-- it's 2x since it's twice the small angle and +3 because it's 3 degrees more than the small angle.
small angle + large angle = 180
Now just substitute!
[tex]x+(2x+3)=180\\3x=177\\x=\frac{177}{3} \\x=59[/tex]
Now that you know what x equals (aka the smaller angle) now you can find the larger angle.
[tex]2(59)+3\\118+3\\121[/tex]
Answer:
The smaller angle equals 59°
The larger angle equals 121°

Determine if ΔUTV and ΔRQS are similar. If so, write the similarity statement.
Question 1 options:
A)

Impossible to determine.
D)
The triangles are not similar.
Solve for x.
Question 2 options:
A)

B)
47
C)
44
D)
48
Answer:
1) B
2) A
Step-by-step explanation:
1) When a triangle is similar it means that all the angle measures are the same.
So for triangle UVT the angle measures are:
U=29.95, V=56.25, T=93.82
For triangle RSQ the angle measures are:
R=29.95, S=56.25, Q=93.82
So the answer is that they are similar (triangle UTV ~triangle RQS)
2) For this problem each sided is proportional because of the parallel lines. (It's been a while since I've done this kind of math but I'll give it a go)
30/25=x/35
25x=30(35)
25x=1050

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar. Consider the given table. The “?” in the table represents the number (blank) because the average rate of change on every interval of the function is (blank).
Answer:
The answers to the blanks are:
381/3The “?” in the table represents the number 38 because the average rate of change on every interval of the function is 1/3.
Step-by-step explanation:
How you can see in the table, after the first values [x=-2, f(x)=5], each time that x add 1, f(x) add 3, (that is the reason why the average rate is 1/3), how you can see below:
2. x = 2 (were added 4 to the first number -2)
f(x) = 17 (were added 12 to the first number 5)
3. x = 5 (were added 3 to the second number 2)
f(x) = 26 (were added 9 to the second number 17)
4. x = 9 (were added 4 to the third number 5)
How in the last column were added 4, you must multiply this value by 3 (remember the average rate), so 4*3 = 12, now:
f(x) = 38 (were added 12 to the third number 26)

Answer:
b=15
Step-by-step explanation:
360-90=270
270+60=330
360-330=30/2=15
Answer:
The measure of angle b is 15 degrees,
Step-by-step explanation:
Both triangles are isosceles. The inside one is also a right triangle. Since the big triangle is isosceles and the two angles add up to 120 degrees, they also have to be equal, meaning ∠P≅∠R=60 degrees. The inside triangle is also isosceles, meaning that m∠a=60°-b, which 60°-b representing the measure of the last angle in the smaller triangle. Since ∠a and the third angle are congruent, they each have to equal 45°. 60°-45°=15°. The measure of ∠b=15°.
If f(x) = 3x - 1, find f(10).

-x - 5y = -29 + 4y - y +5
Im pretty sure its 2 but not exactly
Answer:
Step-by-step explanation:
-x - 5y = -29 + 4y - y + 5
Add x to both sides
-x - 5y + x = -29 + 4y - y + 5 + x
-5y = 4y - y -29 +5 + x {Add the like terms}
-5y = 3y - 24 + x {subtract 3y form both sides}
-5y - 8y = 3y - 24 + x - 3y
-13y = x - 24
Divide both sides by (-13)
y = (x-24)/-13
y = -(x-24)/13

28
SUBMIT ANSWER
Answer:
When using the given information, the diameter of the circle is going to be 28 mL.
Step-by-step explanation:
First, we need to know the formula for finding the area of a circle.
[tex]Area=r^2\pi[/tex]
Now, we need to rearrange the formula so we can find the radius.
[tex]Radius=\sqrt{\frac{A}{\pi} }[/tex]
Next, we plug in the given area into the equation.
[tex]Radius=\sqrt{\frac{615}{\pi}}[/tex]
[tex]Radius=\sqrt{196}[/tex]
[tex]Radius=14[/tex]
Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.
[tex]14 * 2=28[/tex]
So, the diameter of the circle is 28 mL

Question 11 (Multiple Choice Worth 1 points) (05.05 MC) The length of a rectangle is shown below: On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair negative 2, 3, and the point B is on ordered pair 3, 3. If the area of the rectangle to be drawn is 30 square units, where should points C and D be located, if they lie vertically below A and B, to make this rectangle? C(3, −2), D(−2, −2) C(3, −3), D(−2, −3) C(−3, 3), D(−3, −2) C(−2, 3), D(−2, −2)
Answer:
C(3, −3), D(−2, −3)
Step-by-step explanation:
The given segment is 5 units long. (You can subtract the coordinates or count the grid squares to see this.)
In order for the area to be 30 square units, the product of length and width must be 30.
30 = 5×width
30/5 = width = 6
The horizontal line that is 6 units below the one shown is at y = -3. That is, the coordinates of C and D will have y-values of -3. Only one answer choice matches.

C(3, −3), D(−2, −3)

Answer:
B, C and F
Step-by-step explanation:
Given
f(x) = [tex]\frac{7}{2x(x+3)(x-9)}[/tex]
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.
solve
2x(x + 3)(x - 9) = 0
Equate each factor to zero and solve for x
2x = 0 ⇒ x = 0 → C
x + 3 = 0 ⇒ x = - 3 → B
x - 9 = 0 ⇒ x = 9 → F
