Answer:
k= 11/2
Step-by-step explanation:
Answer:
k = 2.5
Step-by-step explanation:
In order to solve this equation we do the following:
[tex]9 = 3(\frac{1}{2} + k)\\[/tex]
Divide both sides by 3 and get...
[tex]3 = \frac{1}{2} + k\\[/tex]
Subtract 1/2 from both sides and get...
k = 2.5
Which of the following is a pair of reciprocals?
A. (3, -3)
B.( 3 1/3, 3/10
C. (2^3, 3^2)
D.(0, 1)
Answer:
B, 3 1/3, 3/10
Step-by-step explanation:
two numbers are reciprocals if when you multiply them, the product is 1. when multiplying 3 1/3 by 3/10 the answer is 1, so you know this is the pair of reciprocals
hope this helps :)
Answer:
B
Step-by-step explanation:
Given a number n then its reciprocal is [tex]\frac{1}{n}[/tex]
A 3 and - 3 are opposites not reciprocals
B
3 [tex]\frac{1}{3}[/tex] = [tex]\frac{10}{3}[/tex] and [tex]\frac{1}{\frac{10}{3} }[/tex] = [tex]\frac{3}{10}[/tex]
Then
( 3 [tex]\frac{1}{3}[/tex] , [tex]\frac{3}{10}[/tex] ) ← are reciprocals

Step-by-step explanation:
The diameter is 106
The radius is 1/2 of the diameter
1/2 ( 106) = 53
The area of a circle is
A = pi r^2
= (3.14) ( 53)^2
= 8820.26 m^2

f(3) is x = 3 for function f(x)
g(7) is x = 7 for function g(x)
Step 2: Solve
Substitute in x [Functions]: f(3) = -2(3) + 3, g(7) = 2(7) + 3Substitute in functions: f(3) + g(7) = -2(3) + 3 + 2(7) + 3Multiply: f(3) + g(7) = -6 + 3 + 14 + 3Add: f(3) + g(7) = -3 + 14 + 3Add: f(3) + g(7) = 14How can you use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3)?
Answer:
To use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3), you can use the following steps:
Rewrite the expression as [5.5+(-2.3)] +(-5.5) + 2.3.
Use the inverse property of addition to rewrite (-5.5) as 5.5, so the expression becomes [5.5+(-2.3)] +(5.5) + 2.3.
Use the inverse property of addition again to rewrite (-2.3) as 2.3, so the expression becomes [5.5+2.3] +(5.5) + 2.3.
Use the associative property of addition to rearrange the terms in the expression, so it becomes 5.5 + 2.3 + 5.5 + 2.3.
Use mental math to add the terms, which gives you a result of 15.8.
Therefore, the sum of [5.5+(-2.3)] +(-5.5 + 2.3) is 15.8.

a. Rectangle ABCD is rotated 90° about the
origin. What are the coordinates of the
vertices of rectangle A′B′C′D′?
b. What are the measures of the angles of
A′B′C′D′?
a. A'-- (2,3) B"-- (-2,3), C'-- (-2,-3), D'-- (2,-3) The formula for rotating a shape 90 degrees clockwise is (x,y) --> (-y,x).
b. 90 degrees because a rectangle has 90 degrees angles, and rotation doesn't change its shape, so it doesn't affect its angles.

Brice is taking a bike tour of the city. The entire tour is 24 7/10 kilometers long. Brice knows that his average biking rate is 4.3 meters per second.
Question 1
Part A
What is Brice's average biking rate in kilometers per hour?
Enter the correct answer in the box.
Brice's average biking rate in km/h is 15.48km/h.
To solve this problem, we just have to convert his speed/velocity from m/s to km/h
Data;
Distance = 24 7/10Speed = 4.3 m/sConversion from meter per seconds to kilometer per hour[tex]1000m = 1km\\and \\(60*60)s =1hr\\[/tex]
This will bring 4.3m/s to
[tex]4.3m/s = km/hr\\\\4.3m/s= 4.3*\frac{(60*60)}{1000} \\4.3m/s = 15.48km/h[/tex]
Brice's average biking rate in km/h is 15.48km/h.

how many solution does 4x-5(2x+1)=6x+1 have
The number of solution the equation 4x - 5 (2x + 1) = 6x + 1 have is one.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
4x - 5 (2x + 1) = 6x + 1
4x - 10x - 5 = 6x + 1
-6x - 5 = 6x + 1
-5 - 1 = 6x + 6x
-6 = 12x
x = -6/12
x = -1/2
This means,
The equation has one solution.
Thus,
The equation has one solution.

Cara's Candles Cara likes candles. She also likes mathematics and was thinking about using algebra to answer a question she had about two of her candles. Her taller candle is 16 cm tall. Each hour it burns makes the candle lose 2.5 cm in height. Her short candle is 12 cm tall and loses 1.5 cm in height for each hour that it burns.
Write an equation for both candles and solve it by either substitution or elimination.
(If someone could please help me out with this, I would really appreciate it. I've been trying to do this for days now and I just can't figure it out..)
(By the way, the equation for the 16 cm candle is y = -2.5x + 16, and the equation for the 12 cm candle is y = -1.5x + 12, I just don't know how to solve it using substitution or elimination.)
please help I don't understand
I WILL give branliest to whoever's right
I really need the answers
Answer: Substitution
Step-by-step explanation: I think that because you have the equations already, you just have to solve for a variable using substitution. Do this by substituting one of the variables with another number. For example, make x=2 in both equations. Now you are free to solve for y and get your answer.
y=-2.5(2)+16
y=11
y=-1.5(2)+12
y=9
You can substitute in any number that makes it easy for you. Also, if you want x, you can substitute y. I'm really, really sorry if that is not helpful, I just told you what I know!
