Answer:
2.98×10^-6 hrs
Step-by-step explanation:
Speed = Distance/Time
Time = Distance/speed
Given
Distance = 17in
Speed= 90mph
Convert inches to miles
1in = 1.578 × 10-5 mile
17in = 17(1.578 × 10-5) mile
17in = 26.826×10^-5miles
Get the time
Time =26.826×10^-5/90
Time = 0.298×10^-5
Time = 2.98×10^-6 hrs
Directions: multiply the whole number and the numerator. Once you find the product divide that by the denominator. 64 divided by 3/8 answer as a mixed number
Answer:
24
Step-by-step explanation:
Given the direction required to solve the problem :
multiply the whole number and the numerator.
Once you find the product divide that by the denominator
Simplify :
64 divided by 3/8
Multiply 64 by the numerator of the fraction :
64 * 3 = 192
Divude the result by the denominator of the fraction :
192 / 8 = 24
Hence, 64 * 3/8 = 24

Answer:
Step-by-step explanation:
For this equation you want to start with signing the equation for the best line of fit. You’re going to take your year in and your rabbitsFrom the table and you’re going to find the slope in the Y intercept which would be your MX and you’re B. If you used as most you want to pull up a table in the graphing calculator and into your data there when you get there and the next box under your table you’re going to put y1~mx1+b There it will show you your slope and your intercept along with other things you will need to know for the equation when you get here sleeping when you said you’re going to round to the second decimal place and then you should get y=8.2x-16451.3 Which will be your best line of fit. Now when you’re trying to estimate the number rabbit at the farm In 2016 you want to put your year where X is so you’ll input your 2016 where x is and you should get 8.2(2016)-16451.3From there you solve it and you’re around to the second decimal space and there you have your just wanna sit and your estimate

The actual answer is C
Step-by-step explanation:
4/7 divided by 2 1/3
Answer:
[tex]\frac{12}{49}[/tex]
Step-by-step explanation:
[tex]\frac{4}{7}[/tex] ÷ 2 [tex]\frac{1}{3}[/tex]
First, change 2 [tex]\frac{1}{3}[/tex] into an improper fraction. It will make the solving process a lot easier.
2 [tex]\frac{1}{3}[/tex] = [tex]\frac{7}{3}[/tex]
So:
[tex]\frac{4}{7}[/tex] ÷ [tex]\frac{7}{3}[/tex]
Now solve by multiplying the reciprocal of [tex]\frac{7}{3}[/tex] which is [tex]\frac{3}{7}[/tex]
So:
[tex]\frac{4}{7}[/tex] × [tex]\frac{3}{7}[/tex] = [tex]\frac{12}{49}[/tex]

82 added to a number is the same as 36
20 points
82=36
t+82=36
82+36=x
None of the above
Answer:
(b) t+82=36
Step-by-step explanation:
When 82 is added to a number the resulting number is the same as 36.
Let t be the number in which 82 is added.
After addition the resulting number = t+82
As the resulting number is the same as 36, so,
t+82 = 36
Hence option (b) is correct.

A softball is thrown into the air with an initial velocity of 5 meters per second from a height of 9 meters.
The function below models the distance of the softball from the ground in meters after t seconds.
How many seconds does it take for the softball to hit the ground?
h(t)=4.9t^2+5t+9
Answer:
0.94secs
Step-by-step explanation:
Given the function below that models the distance of the softball from the ground in meters after t seconds expressed as;
h(t)=-4.9t^2+5t+9
The ball hits the ground when the height h(t) is zero
Substitute h(t) = 0 into the expression and calculate the value of t;
0 = -4.9t²+5t+9
Multiply through by 10;
0 = 49t²+50t+90
-49t²+50t+90 = 0
Factorize;
t = -50 ±√50²-4(49)(90)/2(49)
t = -50±√2500+17640/98
t = -50±√20140/98
t = -50+141.92/98
t = 91.92/98
t = 0.94 secs
Hence it takes 0.94secs for the softball to hit the ground
The probability of a basketball player making a free throw is 76%. In practice she shoots 10 free throws. What is the probability that he makes 7 free throws?
Answer:
Probability is 0.243
Step-by-step explanation:
Probability of success p = 76% = 76/100 = 0.76
Probability of failure q = 1 - p = 1-0.76 = 0.24
We can now proceed to use Bernoulli approximation of the Binomial theorem
We have
P( X = 7) = 10 C 7 p^7 q^3
P(X = 7) = 120 * 0.1465 * 0.013824
P(X = 7) = 0.242946203712
This is approximately 0.243

Brianna is crocheting a scarf as a birthday present for her sister. She started the scarf yesterday and needs to finish it today before her sister's birthday party.
This table shows the relationship between the amount of time (in minutes) Brianna spends crocheting today, x, and the total length of the scarf (in inches), y.
x (minutes) y (inches)
10 19
50 23
60 24
80 26
According to the values in the table, do x and y have a proportional relationship?
9514 1404 393
Answer:
no, the relationship is not proportional
Step-by-step explanation:
The table says Brianna crocheted 19 inches in 10 minutes. If the relation were proportional, Brianna would have crocheted 5×19 = 95 inches in 5×10 = 50 minutes. Her actual length is only 23 inches, so length is not proportional to time.
Solve
3(2x - 5) = 9(10 - x)
Answer:
x=7
Step-by-step explanation:
3(2x - 5) = 9(10 - x)
6x-15=90-9x
6x+9x=90+15
15x=105
x=7
Answer:
[tex]x = 7[/tex]
Step-by-step explanation:
First, we need to expand the brackets:
[tex]3(2x-5)=9(10-x)[/tex] (equation given)
[tex]6x-15=90-9x[/tex]
[tex]15x -15 = 90[/tex] (add [tex]9x[/tex] on both sides)
[tex]15x = 105[/tex] (add [tex]15[/tex] on both sides)
[tex]x = 7[/tex] (divide by [tex]15[/tex] on both sides)

your father pushed a 2-kg box across the floor with a net horizontal force of 10 n. what is the acceleration of the box
Answer:
5 m/s^2
Step-by-step explanation:
Force = mass x acceleration
f = ma
We have the force of 10 N and the mass of 2 kg.
10 N = 2 kg a
divide by 2 on both sides to isolate the a
a = 5 m/s^2
Answer:
[tex]\boxed {\boxed {\sf a= 5 \ m/s^2}}[/tex]
Step-by-step explanation:
The formula for force is:
[tex]F=m*a[/tex]
If we rearrange the formula for acceleration (a) and divide both sides by m we get:
[tex]\frac{F}{m}=a[/tex]
The net force is 10 Newtons. Let's convert the units to make the problem easier later on.
1 Newton=1 kg*m/s²The net force of 10 Newtons is equal to 10 kg*m/s²The mass is 2 kilograms.
[tex]F=10 \ kg*m/s^2\\m= 2 \ kg[/tex]
Substitute the values into the formula.
[tex]\frac{10 \ kg*m/s^2}{2 \ kg} =a[/tex]
Divide. Note the kilograms (kg) will cancel each other out (this is why we converted the units)
[tex]\frac{10 \ m/s^2}{2}=a[/tex]
[tex]5 \ m/s^2=a[/tex]
The acceleration of the box is 5 meters per second squared.

Find the equation of the exponential function represented by the table below:
Answer:
The equation of the exponential function represented by the table will be:
[tex]f(x)= 2(4)^{x}[/tex]
Step-by-step explanation:
We know the equation of exponential function such as
[tex]f(x) = ab^{x}[/tex]
Put x=0, and y=2 in the function
[tex]2 = ab^{0}[/tex]
[tex]2 = a[/tex]
Also x=1, and y=8 in the function
[tex]8 = 2b^{1}[/tex]
[tex]b=4[/tex]
Thus,
[tex]f(x) = ab^{x}[/tex]
[tex]= 2(4)^{x}[/tex]
Therefore, the equation of the exponential function represented by the table will be:
[tex]f(x)= 2(4)^{x}[/tex]
