Answer:
12 hours
Step-by-step explanation:
Given
1 inch = 400 miles
1 inch = 400 miles
multiplying LHS and RHS by 9
1*9 inche = 400*9 miles
9 inches = 3600 miles
Given that on map distance from point A to point B is 9 inches
Actual distance will be 3600 miles as calculated above.
we know that
Time = distance / speed
given
speed = 300 mph
distance = 3600 miles
time = 3600 miles/300 mph = 12 hours
Thus, trip will take 12 hours.
does 4 1/2 times 2 3/4 equal 11 11/48?
4 1/2 times 2 3/4 does not equals to 11 11/48.
It actually equals to 12 3/8

f(x)=3x−4g(x)=−x2+2x−5h(x)=2x2+1j(x)=6x2−8xk(x)=3x2−x+7 Calculate (fh)(x).
Answer:
( f h ) (x) = 6 x² - 1
Step-by-step explanation:
Step(i):-
Given f(x) = 3 x - 4
g (x) = −x²+2 x−5
h (x) = 2 x² + 1
j (x) = 6 x + 2 - 8 x
K (x) = 3 x² - x + 7
Step(ii):-
( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )
= 3 (2 x² + 1 ) - 4
= 3 ((2 x² ) + 3 - 4
= 6 x² - 1
Final answer:-
∴ ( f h ) (x) = 6 x² - 1

to fall a distance
Answer:
C) 3.9 sec
Step-by-step explanation:
You have given the time formula; t = square root of d divided by square root of 4.9.
Well d = 75m
square root of 75 = 8.66
square root of 4.9 = 2.2
8.66 / 2.2 = 3.9363...
t = 3.9 sec

What steps should be taken to calculate the volume of the prism? Select three options.

Use the formula A = bh to find the area of the base.
Use the formula A= bh to find the area of the base.
Use the formula V=Bn to find the volume of the prism.
Answer:
the formula is V=BH
Step-by-step explanation:
if the prism is rectangular prism : it has three dimensions then V=length * height * width
V= L*H*W or V= base*H
or V=BH
in your question it does not show V=BH maybe it is misprint
The volume of the prism is V = Bh , where B is the base area and h is the height of the prism
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
Identify the shape of the base of the prism: The base of the prism can be any polygon, such as a triangle, rectangle, or hexagon. It is important to identify the shape of the base because the formula for calculating the area of the base will depend on the shape.
Calculate the area of the base: Once the shape of the base has been identified, calculate the area of the base using the appropriate formula. For example, if the base is a rectangle, the area would be calculated as length x width.
Multiply the area of the base by the height of the prism: Once the area of the base has been calculated, multiply it by the height of the prism to get the volume. The height is the perpendicular distance between the two parallel bases of the prism.
Hence , by following these three steps, you can calculate the volume of a prism regardless of its shape, as long as you can identify the shape of the base and calculate its area.

The volume of a stack of identical circular drink coasters, each 1 centimeter thick, can be found using the function V(r)=8pi r^2 where r is the radius of a coaster. What does the constant 8 in the function represent?
Answer:
The constant 8 represents the height of the stack and hence the number of coasters. (It represents the number of coasters.)
Step-by-step explanation:
The formula for finding the volume of a cylinder is
V = πr²h
If you we take π =3.14 and h = 1 cm, as given in the question, then we can rewrite the formula for the volume of one coaster as
V = 3.14 * r²
But the formula in this question is
V(r) = 8*3.14 * r² so this means that there are 8 coasters here hence the formula for one coaster being multiplied by 8.
Joe was promised $22.00 and a new CD for taking care of a neighbor’s dog for 7 days. But when the neighbors came home after just 5 days, Joe got the CD and only $14.00. What was the value of the CD?

Since Joe did not get the whole $22 and only $14, then it would only be fair to say that the CD was worth $8.

PLSS HELP SOON Is the sequence arithmetic? (Yes or no) If yes, please also give its common difference. 14) -2.8, -2.2, -1.6, -1.0
Answer:
The sequence is an arithmetic sequence.
Common difference = 0.6
Step-by-step explanation:
Given
-2.8, -2.2, -1.6, -1.0
Required
State if it's an arithmetic progression
Also state its common difference
To know if a sequence is arithmetic or not, we simply check for common difference
Common difference is calculated by subtracting a lower term with its immediate higher time;
In other words
[tex]Common difference = T_2 - T_1 = T_3 - T_2 = T_4 - T_3 = ......[/tex]
Where T represent Term and the number represent their positions;
So, from the given above
[tex]T_1 = -2.8\\T_2 = -2.2\\T_3 = -1.6\\T_4 = -1.0[/tex]
Calculating [tex]T_2 - T_1[/tex]
[tex]T2 - T1 = -2.2 - (-2.8)\\T2 - T1 = -2.2 + 2.8\\T2 - T1 = 0.6\\[/tex]
Calculating [tex]T_3 - T_2[/tex]
[tex]T_3 - T_2 = -1.6 - (-2.2)\\T_3 - T_2 = -1.6 + 2.2\\T_3 - T_2 = 0.6[/tex]
Calculating [tex]T_4 - T_3[/tex]
[tex]T_4 - T_3 = -1.0 - (-1.6)\\T_4 - T_3 = -1.0 + 1.6\\T_4 - T_3 = 0.6[/tex]
Notice that all the above workings gave the same result;
This shows that the sequence is an arithmetic sequence.
The result of each workings above is the common difference
Common difference = 0.6
Write an equation for the nth term of the given geometric sequence
-12,-36,-108...an
Answer:
nth term of the geometric sequence
an= -12*3^(n-1)
Step-by-step explanation:
First term
a= -12
Second term
ar= -36
-12r=-36
r=-36/-12
=3
Third term
ar^2= -108
-12(3)^2
= -12(9)
= -108
nth term of the geometric sequence
an=ar^(n-1)
= -12*3^(n-1)

Which statement is true? A. A sample statistic can never be equal to the population parameter. B. Point estimates are defined for both samples and populations. C. To calculate a sample proportion, we need to know the population size. D. To calculate a point estimate, we need to know the sample size.
Answer: A) A sample statistic can never be equal to the population parameter.
Step-by-step explanation:
The statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.
The following statements should not be considered:
The statistic of the sample should be equal to the parameter of the population as the statistic represent the attribute of the sample and the parameter represent the parameter of the population. Also, each and every sample should have an equivalent chance of using it. The estimation of the point does not define the sample & population as the estimation of the point should be predicted for the parameter of the population.For determining the point estimate, the sample size does not need as the population is required.Therefore we can conclude that the statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.

Write down the example of converting the two numbers to the same exponent:
We conclude that the _____ atom is the greater.
Answer:
2'nd atom
Step-by-step explanation:
There are two atoms one weighs
6.022*10^-29 grams
another weighs
1.66*10^-17 grams
Which atom has a greater mass?
Work:
-29-(-17)=-12
-29 is 12 decimal places smaller than ^-17
0.000000000006.022*10^-17=1.66*10^-17
0.000000000006.022=1.66
0.000000000006.022<1.66
atom 1 < atom 2
We can conclude that the second atom is the greater.
A company has 3 staff positions to fill. If there are 14 candidates, how many outcomes
are possible?
Answer:
364
Step-by-step explanation:
14!/(3!(14-3)
Answer:
364
Step-by-step explanation:
You need to choose 1 out 14 for the first position, then 1 out of the 13 left for the second position, then 1 out the 12 left for the third position.
That gives 14 * 13 * 12 = 2184.
If order mattered, that would be the answer, but in this case, since order does not matter, the 3 positions can be filled in 3 * 2 * 1 ways = 6 ways.
2184/6 = 364

Please answer now ASAP!! I have this assignment at school my teacher wants us to do but I don’t get it. Answer both questions with work!
Answer:
Step-by-step explanation:
1. If m<2 = 32°
the measure for m<4 is 148°
x + 32° = 180°
x = 148°
measure of m<6 = 148° alternate interior of m<4
2. If m<1 = 65°, then m<2 and m<3 are also 65°
Both m<2 and m<3 are vertical angles therefore they are 65°
m<1 and m<2 are corresponding angles therefore they are 65°
