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.

A compound event image occurs when any of the shaded outcomes in the sample space occurs. What is the probability of image?
A.
image
Answer:
[tex]Pr(E) = \frac{1}{9}[/tex]
Step-by-step explanation:
Given
Compound event E
replace "image" with E in the question
Required
The probability of E
From the question, 4 outcomes were shaded.
This implies that
[tex]n(E) = 4[/tex]
And we have:
[tex]n(S) = 36[/tex] --- Sample size
The probability of E is:
[tex]Pr(E) = \frac{n(E)}{n(S)}[/tex]
This gives:
[tex]Pr(E) = \frac{4}{36}[/tex]

Answer:
176 cm^2
Step-by-step explanation:
Area of a triangle = 1/2(b)(h)
*b means base and h means height*
Since there are four separate triangles here, we have to find the area for each and add each area together.
1/2(8)(16)
1/2(128)
64
We can multiple 64 by 2, because there are two triangles of this same size in the kite.
64(2) = 128
1/2(8)(6)
1/2(48)
24
We can also multiply 24 by two since the kite includes two triangles of this same size.
24(2) = 48
48 + 128 =

Ivan is 162.4 centimeters tall and is building a tower out of cans that he wants to be as tall as he is. He wants to know how many cans he will need, but he forgot to measure the length of 1 can. He knows that 10 cans are 56 centimeters tall. If he starts building the tower of cans on a stool that is 28 centimeters tall, how many cans does he need for his tower?
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!

How 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.

Find the area of this circle. Use 3.14 for pie .
Answer:
8820.26 m^2
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

Four friends are told that the average (mean) of their grades for their favorite class is 83.75%.
Kevin got 94%, Elizabeth got 78%, and Katherine got 83%.
Tyler's grade was not revealed. What's Tylers grade?
Answer:
Tyler got 80%.
Step-by-step explanation:
Represent Tyler's average by t.
Then .94 + .78 + .83 + t
-------------------------- = 83.75%
4
Multiplying both sides by 4, we get 2.55 + t = 3.35
so that t = 3.35 - 2.55 = 0.80
Tyler got 80%.
