A 78 kg runner exerts a force of 69 N. What is the acceleration of the runner?(use the formula a=F/m)
Answer:
The answer is 0.88 m/s²Step-by-step explanation:
To find the acceleration given the mass and force we use the formula
[tex]a = \frac{f}{m} \\ [/tex]
where
a is the acceleration
m is the mass
F is the force
From the question
m = 78 kg
F = 69 N
We have
[tex]a = \frac{69}{78} = \frac{23}{26} \\ = 0.8846153...[/tex]
We have the final answer as
0.88 m/s²Hope this helps you

16, 4,1,...
Find the 6th term
Let's see what to do...
_________________________________
Step (1)
Look : 16 , 10 , 4 , ...
It is an arithmetic sequence.
So first we have to find the value of the ratio(( d )) .
To do this, we need to subtract each sentence minus the previous sentence.
So we have : 10 - 16 = - 6
_________________________________
Step (2)
To find the nth sentence in an arithmetic sequence, we must use the following equation :
[tex]t(n) = t(1) + (n - 1)d[/tex]
_________________________________
Step (3)
To find the 6th term just need to put the following parameters in the above sequence.
t(1) = 16 ------ n = 6 ------ d = -6
[tex]t(6) = 16 + (6 - 1)( - 6)[/tex]
[tex]t(6) = 16 + (5)( - 6)[/tex]
[tex]t(6) = 16 + ( - 30)[/tex]
[tex]t(6) = 16 - 30[/tex]
[tex]t(6) = - 14[/tex]

what is the solution to the equation 1/4 x + 2 = -5/8 x - 5
Answer:
x = -8
Step-by-step explanation:
Original Equation:
1/4x + 2 = -5/8x - 5
Add 5 to both sides.
1/4x + 7 = -5/8x
Subtract 1/4x from both sides.
7 = -7/8x
Divide both sides by -7/8
Your answer is -8
Hope I helped :)

how do you solve this equation 19−4c=17
Answer: Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.
Here's how:
Step-by-step explanation:
19−4c=17
19 - 19 - 4c = 17 - 19 Subtract 19 from both sides 19-19 =0 Cancels on the left
-4c = 17-19 subtract: 17-19 = -2
-4c = -2
-4c/4 = -2/-4 Divide both sides by -4
Negatives divided by Negatives have a Positive quotient -4/-4 =1, Cancels
c = 1/2
Solve for u.
8u+ 33 =-7(u-9)
Simplify your answer as much as possible.
u =
8
Х
?
Answer:
u=2
Step-by-step explanation:
8u+ 33 =-7(u-9)
Distribute
8u+ 33 =-7u+63
Add 7u to each side
8u+33+7u = -7u+63+7u
15u+33 = 63
Subtract 33 from each side
15u +33-33 = 63-33
15u = 30
Divide each side by 15
15u/15 = 30/15
u =2
Answer & Step-by-step explanation:
- 22 = -8u + 6(u-7)
-22 = -8u + 6u - 42
8u - 6u = 22 - 42
2u = -20
u = -20/2
u = -10

find surface area please
Answer:
203
Step-by-step explanation:
When calculating surface area, you add the area of each side.
Base: LxW = 7x7 = 49
Triangle Sides: 1/2 b x h = 1/2(7) x 11 = 38.5
4 sides: 38.5x4 = 154
154+49 = 203

There are also only 19 numbers because they need to be less than 20 like the question indicated. Therefore, the answer is D.
Last year during the July 4th holiday, Americans ate about 150,000,000 hot dogs. Over the entire year, Americans ate a total of about 2 x 10^10. Compute how many times greater the total number of hot dogs eaten by Americans last year was than the number of hot dogs eaten during the 4th of July holiday. Round your answer to the nearest one.
Answer:
133 times
Step-by-step explanation:
First, convert 2 x 10^10 out of scientific notation:
20,000,000,000
Since this is the total amount of hotdogs, divide by the number eaten on July 4th:
20,000,000,000 / 150,000,000 = 133.3333333
Round to nearest one: 133 times
The total number of hot dogs eaten by Americans last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.
What is division?A division is a process of splitting a specific amount into equal parts.
We have,
The number of hot dogs that ate on 4th July holiday= 150,000,000
The number of hot dogs that ate last year = 2 x [tex]10^{10}[/tex]
The number of times the total number of hot dogs eaten last year than the number of hot dogs eaten during the 4th of July holiday is:
Number of hot dogs eaten in July x M = Number of hot dogs eaten in the entire year
150,000,000 x M = 2 x [tex]10^{10}[/tex]
M = 2 x [tex]10^{10}[/tex] / 150,000,000
M = 20,000,000,000 / 150,000,000
M = 133.33
Rounding to the nearest one we get,
M = 133
Thus the total number of hot dogs eaten last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.
