If m is a positive integer, what is the least value of m for which 180 is a factor of 105m
Answers
Answer:
Step-by-step explanation:
If 180 is the factor of 105 m, then the factors of 180 should also be the factors of 105 m.
Factors of 180 = 15 * 12
Factors of 105 m = 15 * 7 * m
The least value of m is = 12
15*12 is 108
So m=12

A circle’s circumference is 600 m.
What is a good approximation of the circle’s area? 1. 300\ m^{2} 2. 3,000\ m^{2} 3. 30,000\ m^{2} 4. 300,000\ m^{2}
Answers
The area of the circle is approximately 30,000 \(m^{2}\)
The circumference of the circle is given as 600m.
And we know that circumference = \(2\pi r\) where r is the radius of the circle.
Therefore,
\(2\pi r = 600\)
\(r = \frac{600}{2\pi }\)
\(r = \frac{300}{\pi }\)
Now, we know that area of the circle = \(\pi r^{2}\)
Putting the value of r in this, we get
area = \(\pi (\frac{300}{\pi } )^{2}\)
area = \(\pi.\frac{300}{\pi } .\frac{300}{\pi }\)
Therefore, area of the circle = 28,647.889 \(m^{2}\)
Therefore, the correct answer is 30,000 \(m^{2}\)

Answers
Answer:
A movie is $2.5
A video game is $6
Step-by-step explanation:
Pre-SolvingWe are given that Ann had rented 2 movies and 5 video games for a total of $35.
We also know that she also rented 8 movies and 3 video games for a total of $38.
We want to know how much a movie costs, and how much a video game costs.
If a movie costs x dollars, then a video game costs y dollars.
This means that costwise, 2 movies will cost 2x, and 5 video games will be 5y.
8 movies will cost 8x, and 3 video games will cost 3y.
So, we will have two equations:
2x + 5y = 35
8x + 3y = 38
We now have this system of equations, which we can solve.
Let's solve this by elimination.
To eliminate, we need to clear one of the variables, and solve for the other one.
To do this, we need to make sure that one variable has the same coefficient with opposite signs (e.g. -3x and 3x). We might need to multiply one equation by a number in order to achieve this.
We can multiply 2x + 5y = 35 by -4.
-4(2x + 5y) = -4(35)
-8x - 20y = -140
We can rewrite the equations:
-8x - 20y = -140
8x + 3y = 38
They can be added together. The result will be:
-17y = -102
Divide both sides by 017.
y = 6
We found y, but now we need to find x.
We can substitute 6 as y into 2x + 5y = 35 or 8x + 3y = 38 to find x.
Taking 2x + 5y = 35 for instance:
2x + 5(6) = 35
2x + 30 = 35
Subtract 30 from both sides.
2x = 5
Divide both sides by 2
x = 2.5
Recall that x = price of a movie, and y = price of a video game.
Therefore, a movie is 2.5 dollars, and a video game is 6 dollars.
and a snack is $6

Answer:
The speed of a car is x miles per hour.
The total distance the car travels in
30 minutes is y. ....>>> y = 0.5x
The cost to produce a table, y, is two
times the cost to produce a chair, x. ..> y = 2x
The time required to bake a chocolate
muffin, y, is 2 minutes more than the
time required to bake a vanilla muffin, x.....>> y = x + 2
Tina’s age, y, is 5 years more than
her brother Tim’s age, x. .......>> y = x + 5
Step-by-step explanation: The only really tricky one is the "speed of the car ..." because the speed is given in miles per hour and the time is given in minutes so that is 0.5 hour times time
Otherwise, "times" means multiplication and "more than" means addition.

Answers
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

Which tree grew at a slower rate for the first year?
Two trees were planted at the same time. Tree A grew 4.15 inches per month for the first year. Tree B grew 4.2 inches per month for the first year.
Answers
4.15 is less than 4.2 and Tree A is growing at the “lesser” rate, making it the slower growing tree.
Answer:
Tree A
Step-by-step explanation:
Let me put this question a different way. Which tree will be the tallest at the end of the year?
Well, let's think about it. 12 months later, Tree A will have grown 4.15x12=49.8 inches. Tree B will have grown 4.2x12=50.4 inches. As 50.4 is greater than 49.8, we can see it is Tree B that was the tallest at the end of the year. So we can conclude that Tree B grows faster. This would mean that Tree A grew at a slower rate for the first year.

What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The triangle is shown in the picture:
The rule of reflection across the x-axis:
(x, y) → (x, -y)
The rule for the transformation is:
5 units to the left
(x, y) → (x-5, y)
A'(-1, 8) → A''(-1-5, 8) = A''(-6, 8)
B'(-2, -2) → B''(-2-5, -2) = B''(-7, -2)
C'(5, -2) → C''(5-5, -2) = C''(0, -2)
Thus, the coordinates of the vertices of the final image are A‘ (-6, -8), B‘(-7, -2), and C‘(0, -2) option (B) is correct.
