The current price for gasoline is $3.049 per gallon. A customer puts 7.45 gallons in her car. How much does she pay for the gas? Round your answer to the nearest cent.
Answer:
$22.72 for gas
Step-by-step explanation:
If each gallon costs $3.049, then we multiply the cost of each gallon by 7.45
3.049 x 7.45 = 22.71505
As the question asks us to round to the nearest cent in 22.71505, we would round up.
Your answer is $22.75 for gas
Simon and Andrew see a speed limit sign that says 65 kilometers per hour. They decide to convert this speed limit to miles per hour. They each do the conversion separately and come up with different answers. Their work is shown. Who is correct? Explain.
Answer:
40.38912735 or about 40 miles per hour (rounded to the nearest whole number)
Step-by-step explanation:
1.) You want to convert kilometers per hour to miles per hour.
2.) There are 0.62137119 miles in 1 kilometer.
3.) Multiply 65 by 0.62137119
4.) That equals 40.38912735
5.) This answer can be rounded to 40 mph.

An object is traveling at a steady speed of 9 4/5 mi/h. How long will it take the object to travel 2 1/5 miles? First round to the nearest integer to find the estimated answer. Then find the exact answer.
Answer:
Time taken by the object = 14 minutes
Step-by-step explanation:
Speed of an object = [tex]9\frac{4}{5}[/tex] miles per hour ≈ 9.8 miles per hour
Distance covered by the object = [tex]2\frac{1}{5}[/tex] miles ≈ 2.2 miles
Formula to calculate the distance in the time 't' is,
Time taken by the object = [tex]\frac{\text{Distance traveled}}{\text{Speed of the object}}[/tex]
= [tex]\frac{2.2}{9.8}[/tex]
= 0.2245 hours
= 13.47 minutes
≈ 14 minutes
Therefore, distance traveled by the object to cover 2.2 miles = 14 minutes.

To get the 10% discount, a shopper must spend no less than $300.
Tell whether the blue figure is a translation of the red figure.
The blue figure !
I a translation of the red figure.
Answer:it is a translation
Step-by-step explanation:a translation is just a movement up down left or right not diagonal you’re just moving it up down left or right across the grid
Answer:
Yes
Step-by-step explanation:
Because a translation moves a shape up, down, or from side to side but it does not change its appearance in any other way. The translation is an example of a transformation. A transformation is a way of changing the size or position of a shape. Every point in the shape is translated at the same distance in the same direction.

Answer:
67/24
Step-by-step explanation:
Remember PEMDAS
First you solve the parenthesis which is 11/12.
Then do exponents 2^4=16
For division do left to right so 2/3 ÷ 16 = 1/24
and the other division is 11/12 ÷ 1/3 = 11/4
Add the two 1/24 + 11/4 = 67/24
67/24 is the answer

Katie completes 2/3 of a craft project in 3/4 of an hour. At this rate, what fraction of the craft project does Katie complete in one hour? Give your answer in fraction form. *
Divide the quantity done by the time:
2/3 / 3/4
When dividing by a fraction flip it over and change divide to multiply:
2/3 x 4/3 = (2 x4) / (3x 3) = 8/9
In 1 hour she will complete 8/9 of the project.
Answer: in one hour she will complete 8/9 of her projec!

Answer:
3900000000000000000000000000000000 multiplied by 1550000000
Step-by-step explanation:
A decillion is a number followed by 32 zeros. This would take very long to solve, so I broke down each number. A calculator cannot accept numbers this large. You could also do 6.045e+43.

x = 7 + 3y
5x + 6y = 14
Which ordered pair (x,y) is the solution to the system of equations above?
x = 7 + 3y
or, x - 3y - 7 = 0 ........ (i)
5x + 6y = 14
or, 5x + 6y - 14 = 0 .........(ii)
To Find:The value of x and y.
Solution:By dividing eq. ii by 2, we get
5/2x + 3y - 7 = 0 ........ (iii)
By adding eq. i and eq. iii, we get
15/2x = 0
or, x = 0 ........(iv)
By putting eq.(iv) in eq. (i), we get
0 - 3y - 7 = 0
or, -3y = 7
or, y = -7/3
Answer: ( 0, -7/3 )The value of x and y is 0 and -7/3 respectively.
if
f(x)=x^2+2x-4
and
g(x)=3x+1
find
f(g(x))=__x^2+__x+__
Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1
Reduce the fraction 12/24 to the simplest form. Make sure that it can not be simplified any further. *

please awnser soon
The simplest form of the number 12/24 is,
⇒ 1 / 2
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The fraction is,
⇒ 12 / 24
Now, We can simplify the fraction in simplest form as;
⇒ 12 / 24
⇒ 6 / 12
⇒ 3 / 6
⇒ 1 / 2
Thus, The simplest form of the number 12/24 is,
⇒ 1 / 2

A man (M) is standing halfway between a tree (T) and a lamppost (L). What is the value of x?
T
M
L
(2x + 8) m
(3x – 2) m
I don't understand what I have to do and how to get the answer is there anyway someone can tell me???
Answer :
The value of x is 10.
Explanation :
Given that,
TM = (2x+8) m
ML = (3x-2) m
If a man (M) is standing halfway between a tree (T) and a lamppost (L).
The half distance is TM and half distance is TL.
So, Both half distance will be equal.
We need to calculate the value of x
Using given data
[tex]TM=ML[/tex]
Put the value into the formula
[tex]2x+8=3x-2[/tex]
[tex]2x-3x=-8-2[/tex]
[tex]-x=-10[/tex]
[tex]x=10[/tex]
Hence, The value of x is 10.
