Hello! Im stuck on this math question. The two triangles displayed are scaled copies of one another. the first question is "What is the scale factor?" the second question is "what is the value of x? "
Answers
Answer:
scale factor = 2.5
x = 10
Step-by-step explanation:
to find the scale factor, divide 10 by 4.
use the answer and divide it by 25 :)
________
10÷4=2.5
25÷2.5=10
The scale factor is 2.5 and the value of x will be 10.
What is a scale factor?The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making. The scale factor is the ratio of the scaled size to the original size.
Given that one triangle has the sides x and 4 and another has 25 and 10.
The scale factor will be calculated as below:-
Scale factor = 10 / 4
Scale factor = 2.5
Use the answer and divide it by 25. The value of x will be calculated as below:-
x = 25÷2.5
x = 10
Therefore, the scale factor is 2.5 and the value of x will be 10.

What is the common difference in the arithmetic sequence 30, 27, 24, 21, 18...?
Answers
Answer:
-3
Step-by-step explanation:
To find the common difference take the second term minus the first term
27 - 30 = -3
Check by taking the third term and subtracting the second term
24 - 27 = -3
The common difference is -3
Describe how to solve 2x + 36-4x -10 ) = 10 to a middle schooler. Show all the steps and tell
us how you can check if it is correct.
Answers
Answer:
First you would have to combine the numbers that are the same, so combine all the X's and the other numbers, with out a variable (without an X). The numbers with X are 2x and -4x, so you add them, you should have 2x (2+ (-4)= 2) your equation should look like this : 2x + 36 - 10= 10
Next you need to combine the other numbers, 36 and -10, add them, and you should get 26. Your problem should look like this 2x+26=10
Next you will need to subtract 26 from each side, what you do to one side of the equal sign you must do to the other. Your problem should look like this : 2x=-16
To find X you have to get X alone, so you have to divide how many x's there are, 2, so divide both sides by 2 (rembering that what you do to one side you must do to the other). So you should have x= -8

"A clock is positioned on an auditorium wall with its center 9 feet above the floor. The second hand is 10 inches long and continuously moves around the clock. Let x represent the time in seconds measured from noon on a given day. Which f(x) represents the height above the floor, in feet, of the tip of the second hand?"
Answers
Answer: f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.
Step-by-step explanation:
When we have a circular motion, we can write this as:
f(x) = A*sin(k*x + f) + A*cos(k*x + f) + C.
where:
k is a constant that depends on the period.
f is a phase shift.
C is the mean height of the circular motion, in this case will be equal to the height of the center, that is 9ft.
C = 9ft.
A is the amplitude of the motion, in this case is equal to the radius, that is equal to the lenght of the second hand
A = 10in
But we should write both quantities in the same units, so we have:
1ft = 12in
then:
C = 9ft = 9*12in = 108in
Then our equation is:
f(x) = 10in*cos(k*x + f) + 10in*sin(k*x + f) + 108in
now, x = 0s coincides with the noon
so at x = 0s, the second hand is pointint to the twelve, this means that is in the max height, so we have:
F(0s) = 10in*cos(0 + f) + 10in*sin(0 + f) + 108 in
Now, the maximum value will be when the value inside the sinusoidals is 0.
(because cos(0) = 1 and sin(0) = 0)
then we have that f = 0.
Now, we know that it takes 60 seconds to do a full revolution, and for the sinusodial functions the period is 2*pi
Then we have:
c*60s = 2*pi
c = 2*pi/60s.
Then the equation is:
f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.

Tell whether the statement "All integers are rational numbers" is true or false. Explain your choice.
Answers
Answer:
True, all integers are rational numbers.
Step-by-step explanation:
Because each integer can be written as n/1 and integers can be positive and negative. For example, 3= 3/1 , 3 is the rational number. But all rational numbers like 1/2 =0.5 are not an integer. (fractions, decimals are not integers.)
What value of y satisfies the system of equations {9x+2y=24y=6x+19
Answers
Step-by-step explanation:
Equation 1: 9x + 2y = 24y, 9x = 22y, x = 22/9 y.
Equation 2: 24y = 6x + 19,
24y = 6(22/9 y) + 19
24y = 44/3 y + 19
28/3 y = 19
Hence, y = 19 * 3/28 = 57/28.
