Answer:
Angle 0 is 6.28/3. or 2.093.
Step-by-step explanation:
Pie is an irrational number, so it will be repeating forever. A simple way to get pie is just 3.14. 3.14 times 2 is 6.28. Divide 6.28 by 3 to get 2.093 repeating, but simplified is 2.093.
Martin has a combination of 33 quarters and dimes worth a total of $6. Which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, Martin has?
q + d = 6 25q + 10d = 33
q + d = 6 0.25q + 0.1d = 33
q + d = 33 25q + 10d = 6
q + d = 33 0.25q + 0.1d = 6
Answer:
q + d = 33 0.25q + 0.1d = 6 Option D
Step-by-step explanation:
The system of linear equation that can be used to find the number of quarters, q, and the number of dimes, d, Martin has is as follows:
q + d = 33
0.25q + 0.1d = 6
Martin has a combination of 33 quarters and dimes worth a total of $6.
Therefore,
q = number of quarters
d = number of dimes
The linear equation can be represented below:0.1 dollars = 1 dime
0.25 dollars = 1 quarters
Therefore,
0.25q + 0.1d = 6
The quarters and dimes total 33. Therefore,
q + d = 33Therefore, the combined equation will be as follows:
q + d = 33
0.25q + 0.1d = 6

A picture that measures 10 cm long is reduced on a copy machine to 4 cm long. If the width of the original picture is 6 cm, what is the width
of the reduced picture? Set up a proportion to solve this problem?
2.4 cm
Step-by-step explanation:
10/4 = 6/x
x = width of reduced picture
24 = 10x (cross multiplication)
24/10 = x
2.4 = x
The width of the reduced picture is 2.4 cm.

Solve the equation below for x. cx-4=7
A. x=3/c
B. x=c/3
C. x=c/11
D. x=11/c
Answer:
C
Step-by-step explanation:
Answer:
D. x = 11/c

you add 4 to both sides so you can make the x by itself.
we are left with cx = 11
you divide c to both sides

A contracting company rents a generator for 6 hours and a heavy duty saw for 6 hours total cost of $48 for another job the company rents the generator for 4 hours and the saw for 8 hours for a total cost of $40 find the hourly rates
Answer:
the hourly rates are $8 and $10 respectively
Step-by-step explanation:
Given that
The generator rents for 6 hours and the total cost is $48
And, for another job The generator rents for 4 hours and the total cost is $40
We need to find out the hourly rates
For the first one
= $48 ÷ 6 hours
= $8
For the second one
= $40 ÷ 4 hours
= $10
Hence, the hourly rates are $8 and $10 respectively

which of these figures has rotational symmetry?
Answer: Choice C
We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.
The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. The correct option is C.
What is Rotational Symmetry?The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. When turned 180 degrees or with specific angles, clockwise or anticlockwise, many geometrical forms appear to be symmetrical. Examples include squares, circles, hexagons, and more.
The shape that has a rotational symmetry is option C, which is a parallelogram.
