If Chad drove 168 miles in 2 hours, how many hours will it take Chad to drive 840 miles traveling at the same rate?
Answer:
10 hours
Step-by-step explanation:
First we need to find the rate Chad is driving. The rate is equal to distance/time, so we do 168/2, which is 84 mph. Then we have to find the time, which is distance/rate, so that would be 840/84, which is 10 hours.
Answer:
10 hours
Step-by-step explanation:
If Chad drove 168 miles in 2 hours than he drove 84 miles in one hour. If he drove 840 miles than you divide 840 by 84 and you get 10 hours. To check your work you can do 84*10= 840 miles 84=representing the miles per hour and 10=representing the amount of hours he drove.

HELP PLEASE! 40 POINTS AND WILL MARK BRAINLIEST.
Describe how to find the 12th term from the sequence below.
f(1)=4
f(n)=f(n-1)+5
The first term, f(1) = 4, to find the second term,
which is f(2-1) = f(1) = 4, so second term, f(2) = 4+5
hence 9, to find the terd term,
which is f(3-1) = f(2) = 9, so terd term, f(3) = 9+5
hence 14, so common difference is 5.
12 term is 59.

What is it?
7m-7-6m-16=1+4m
7m-7-6m-16=1+4m
7m - 6m - 7 - 16 = 1 + 4m
m - 23 = 1 + 4m
m - 23 + 23 = 1 + 23 + 4m
m = 4m + 24
m - 4m = 4m - 4m + 24
-3m = 24
m = 24: (-3)
m = - 8
hi again,

Calculate the probability of rolling a 1 or 2 when using two dice (order does NOT
matter). Now calculate how often a 1 or 2 appeared in the scenario above against the
total number of appearances. Explain why these two numbers are the same or different.
The probability of rolling a 1 or a 2 is P = 4/9, this means that around 4/9 out of the N times we perform the experiment, we will see a 1 or a 2.
How to find the probability?
We assume that each number has the same probability of rolling up in both dices.
So, in each dice, the probability of rolling a 1 or a 2 is 2 out of 6, or:
p = 2/6 = 1/3
And if we get these on one of the dice, we don't want them in the other,
The probability of not rolling a 1 or a 2 is:
q = 4/6 = 2/3
The joint probability is the product of the two individual probabilities:
P = (1/3)*(2/3)
But, we also need to consider the case where we don't get an 1 or a 2 in the first dice roll, and we do get it on the second dice, then there are 2 permutations, so we need to add a factor 2.
P = 2*(1/3)*(2/3) = 4/9
Now we want to find how often a 1 or a 2 appear against the total number of appearances.
If the total number of appearances is N, then in 4/9 of these, the number 1 or 2 will appear, this is:
N*(4/9) times.

What is the solution of: 4-2x/7 - 3x+2/3
Answer:
(-27x -2)/21
Step-by-step explanation:
Perhaps you want to combine the two fractions. This is done using a common denominator.
[tex]\dfrac{4-2x}{7}-\dfrac{3x+2}{3}=\dfrac{3(4-2x)}{7\cdot3}-\dfrac{7(3x+2)}{7\cdot3}\\\\=\dfrac{3(4-2x)-7(3x+2)}{21}=\dfrac{12-6x-21x-14}{21}=\boxed{\dfrac{-27x-2}{21}}[/tex]

Which 3-D figure matches the surface area formula?
Figure A
Figure B
Figure C
Figure D
Answer:
D
Step-by-step explanation:
you mean the formula is 4×pi×r² (not 4×pi/r²), right ?
then the correct answer is the sphere (ball).
the surface area of a cylinder is
top and bottom circle area = pi×r² each = 2×pi×r² both
and the mantle is 2×pi×r×height
the surface area of a block has nothing to do with pi.
it is the sum of 6 rectangles.
the surface area of a cone is
A = πr(r + sqrt(h² + r²))
