Answer:
1:1000
2,100 kg
Step-by-step explanation:
A linear scale of 1:10 means a volume scale of 1:1000.
The ratio of the volumes is model:real = 1:1000.
The mass is proportional to the volume.
The real car has a volume 1000 times the volume of the model, so its mass is also 1000 times the mass of the car.
mass of real car = 1000 × 2.1 kg = 2100 kg
Kang Tae Moo thinks of a number. He adds 13 to the number. He multiples the result by 3. This gives the same result as if he multiplied the number by 9 and then subtracted 3. What number is Kang Tae Moo thinking of?
Answer:
7
Step-by-step explanation:
We can setup this equation as x representing his number. (x+13) * 3 = 9x -3.
Now, we just need to solve for x.
3(x+13)=9x-3
x+13=3x-1
14=2x
x=7

What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The sales of a certain product after an initial release can be found by the equation,
⇒ s = 12 √4t + 10
where s represents the total sales (in thousands) and t represents the time in weeks after release.
Here, The equation is,
⇒ s = 12 √4t + 10
where, s represents the total sales (in thousands) and t represents the time in weeks after release.
We put t=1,2,3,.....,12 and create a table
t s = 12 √4t + 10

The sum of two numbers is 21. Their product is 108. What are the two numbers?
Answer:
9 and 21
Step-by-step explanation:
First we can write the factors of 108:
1,108
2,54
3,36
4,27
6,18
9,12 - these 2 numbers add up to 21 so these 2 numbers is our answer.
Answer:
12 and 9
First, divide 108 by a relatively low number, 12[tex]108 / 12 = 9[/tex]
Now that we have 9, multiply 9 by 12[tex]9 * 12 = 108[/tex]

Question 2
Do the side lengths form a Pythagorean triple?
Answer:
Soln:
Step-by-step explanation:
Here,
Base(b) =9
Opposite/Perpendicular (p)= x
Hypotenus (h) = 24
We know,
(p)^2 = (h)^2 - (b)^2
(x)^2 = (24)^2 - (9)^2
x^2 = 576 - 81
x^2 = 495
x = root under 495
Answer:
1- 22.2486 2- No
Step-by-step explanation:
1:
[tex]b = \sqrt{ c^{2}- a^{2}[/tex]
C is the hypotenuse, or longest side of the triangle (24).
A is the one length we have besides the hypotenuse(9).
[tex]b = \sqrt{ 24^{2}- 9^{2}[/tex]
b = 22.2486
2:
No, because if it was a Pythagorean triple, it would follow the equation [tex]a^{2} +b^{2} =c^{2}[/tex].
[tex]9^{2} + 22.2485^{2} \neq 24^{2}[/tex].

a) 1/10
b) 1/45
c) 17/10
d) 1/5
e) 2/5
Answer:

P=p1+p2, where p1 - when the 1st attempt is correct, p2 - when the 2d attempt is correct;
2) p1=1/10; p2=1/9, then the required probability:
P=1/10 + 1/9 ≈ 1/5.

As is often the case with multiple choice questions, you only need to find part of a correct answer to be able to make the right choice.
The number line picture shows the left-most point has a value less than -1. That means the numerator of its negative fraction will be greater than the denominator. The only fraction like that on the list is -4/3, and the only answer choice with that listed first is choice D.

Consider this dilation.
(a) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b) What is the scale factor? Explain and show your work.
ANSWER BOTH PARTS YOU MAY GET EXTRA POINTS!
Answer:
reductionscale factor 1/2Step-by-step explanation:
The usual English meanings of the words "reduction" and "enlargement" apply to geometrical figures.
(a)Figure A'B'C'D' is smaller than figure ABCD, so represents a reduction.
__
(b)Every coordinate of every image point is half as far from the origin in A'B'C'D' as in the original figure ABCD. For example, the x-coordinate of C' is 2, and the x-coordinae of C is 4. The dilation factor is the ratio of these values:
k = Cx'/Cx = 2/4 = 1/2
The scale factor is 1/2.
Which values of m and b will create a system of equations with no solution? choose 1 options.
Answer:
The graph of a linear equation is a straight line. The "solution" to a system of two linear equations is the point where the two lines cross. If the two lines are parallel, they never cross; hence parallel lines have no solution. Two lines are parallel if they have the same slope (the m value in y = mx+b). One of your equations is y = -2x + (you left the y-intercept out). The slope is -2. So any line with a slope of m = -2 will be parallel to this line and will not cross it. The second line also needs a different value of b, the y-intercept. Otherwise it is the same line and every point is a solution. So if your equation is:
y = -2x + 1
Then any equation of the form y = -2x + b, b≠1 will create a system with no solution. Hence the values of m and b are m = -2, b ≠ 1.

x=4 (Vertical angles have to be equal to each other! If one side is 46 then the side vertical to it is 46!) **Plug number in for x to verify once again!**
Step-by-step explanation:
You need to understand vertical angles!!
Vertical Angles must be congruent and equal to each other!
You need to do:
10x+6=46
Subtract 6 from both sides
10x=40
Do 40 divided by 10
x=4
To verify: plug 4 for x which should be 40 added to 6 is 46!

OD. (a+b)2 = 22 + 2ab+ b2

Answer:
A
Step-by-step explanation:
If we start from top to bottom all we have to do is check which ones are not equal.
The first one is
[tex]a^2(b+c) = a^3(\frac{b}{a}+c)[/tex]
If we multiply is out we get
[tex]a^2b+a^2c = a^3*\frac{b}{a}+a^3c\\\text{which turns into}\\a^2b+a^2c=a^2b+a^3c[/tex]
That is NOT equal to the other. Making the answer A.

The slope of a line is -1/3. Find the slope of a line that is perpendicular to this line.
Answer: 3
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of each other.
Answer:
Slope = 3
Step-by-step explanation:
The question is asking us to find the slope of the line that is perpendicular to the line whose slope is -1/3.
Main idea: Perpendicular lines have slopes that are opposite reciprocals.
So our task boils down to finding the opposite reciprocal of -1/3.
First, we change the sign from negative to positive. We get 1/3.
Then, we turn the number over. We get 3.
Therefore, the slope is 3.

The number of trees that are less than 7 trees as shown in the stem-and0leaf plot is: 7 trees.
What is a Stem-and-leaf Plot?In a stem-and-leaf plot, data points are represented in leaves and stems. For example, representing height of trees as 5 || 8, means a data point representing a height of a tree measuring 5 ft and 8 inches tall.
From the stem-and-leaf plot given, the data points that are below 7 feet are 7 in number, which range from 6 ft and 9 inches down to 5 ft and 8 inches.
