Find the scale factor of trapezoid QRST if it’s dilated to Q’R’S’T’. Type your result in the empty box provided below. HELPP PLEASE!!!!!!
Answer:
5 units
Step-by-step explanation:
its hard to tell but i think it dilated 5 units
We want to find the scale factor at which QRST is dilated to form Q'R'S'T'
We will find that the scale factor is 2.
In a general dilation, we will see that all the measures change in the same way, by the scale factor.
This means that:
QR*k = Q'R'
RS*k = R'S'
And so on, where k is the scale factor.
Then we can just find one of the equivalent measures in both trapezoids and find the value of k.
For example, we have:
Q'R' = 8
QR = 4
Replacing these on the above equation we get:
4*k = 8
k = 8/4 = 2
k = 2
The scale factor of dilation is 2.

The mean of four number is 30. if three of the numbers are 12, 50, and 48 what's the fourth number?
Answer:
if the mean of 4 numbers is 30 then that means that the total of all the numbers added together must add up to 120 (30 x 4)
then you subtract the three numbers that you have from the total
120-12-50-48 = 10
so the last number is 10

Burj Khalifa in Dubai is the tallest building in the world, standing at 828 meters. An adjacent
building, 100 meters away, stands at 550 meters tall. What is the angle of depression from Burj
Khalifa to the adjacent building?
Answer:
Approximately 70 degrees
Step-by-step explanation:
If we make a right triangle connecting the two buildings, we get a triangle with height 278m and length 100m
We can connect these two values to the theta by using the inverse tan formula
arctan(278/100) = 70.21572110836 degrees.
The angle of depression is approximately 70 degrees

You want to choose the number line graph that appropriately represents the inequality 0 < x ≤ 26.
Graphing inequalitiesThe given compound inequality is conveniently written with the "arrows" pointing to the left. This means the lower limit of the variable is on the left side of the inequality, just as it is on the left end of the number line graph.
The inequality symbols used are "less than" (<) and "less than or equal to" (≤). The "less than" symbol is represented on a number line graph by an open circle. The "less than or equal to" symbol is represented by a filled dot on the number line.
This means you are looking for a graph that has an open circle on the left end of a solid line, and a filled dot on the right end. Only graphs B and C have finite-length lines, and only graph C has a filled dot at the right end.
Car seatsIn English, the word "between" often implies "and including" when it is describing an interval between two limits. Here, you are given 3 car seat specifications:
A: 0 < x ≤ 26 . . . . . up to 26 lbsB: 18 ≤ x ≤ 35 . . . . . between 18 and 35 poundsC: 26 ≤ x ≤ 75 . . . . . between 26 and 76 poundsThe seats appropriate for a 33-lb child would be seats B and C, because 33 is included in each of those intervals.
Use the percent formula, A = PB, where A is P percent of B, to answer the following question. What is 24% of 60?
It should be noted that 24 percent of 60 is 14.4.
How to calculate the percentage?The question is to calculate 24% of 60.
This will go thus:
= 24% × 60
= 24/100 × 60
= 0.24 × 60
= 14.4
Therefore, 24% of 60 is 14.4.

Brandon is going to invest in an account paying an interest rate of 5% compounded quarterly. How much would Brandon need to invest, to the nearest dollar, for the value of the account to reach $490 in 16 years?
Answer:
Brandon wants $490 in 16 years by investing "x" dollars in an account that pays 5% compounded quarterly. How much is "x"?
Principal = Total / [ (1 + (r/n) )^ n * years]
n = 4 (for compounded quarterly)
Principal = 490 / [ (1. + (.05/4)) ^ 4 * 16]
Principal = 490 / [ (1.0125)^ 64]
Principal = 490 / 2.2145324106
Principal = 221.2656710971
So, if we invested 221.27 for 16 years at 5% compounded quarterly interest, we would have a total of $490.00

Answer:
27n+66p and 12x+75y+21
Step-by-step explanation:
The greatest common factor is 3 for 27n + 66p and 12x + 75y + 21.
What are Factors?Factors of a number or an algebraic expression are the numbers or expressions which divides the given number evenly.
For example, 10 = 2 × 5
So we can say that 2 and 5 are factors of 10.
Greatest common factor of two numbers or expressions, as the name suggests is the greatest of all the common factors of the given numbers or expressions.
Consider 27n + 66p
Factors of 27n are 1, 3, 9 and 27
Factors of 66p are 1, 2, 3, 6, 11, 22, 33 and 66
Greatest common factor of both = 3
Consider 12x + 75y + 21.
Common factors of three of them are 1 and 3.
Greatest common factor is 3.
Hence the expression with greatest common factor as 3 are 27n + 66p and 12x + 75y + 21.

The graph of y= 8x² + 7x - 5/5x² + 2x + 6 has a horizontal asymptote with equation (enter the equation of the horizontal asymptote)
The horizontal asymptote of the rational function y = (8 · x² + 7 · x - 5) / (5 · x² + 2 · x + 6) is y = 8 / 5.
How to determine the equation of a horizontal asymptote
A horizontal asymptote of a rational function is an horizontal line equations to which the rational function tends to when x tends to the infinite. The horizontal asymptote exists whether the lead grade of the numerator is not greater than the lead grade of the denominator.
Now we proceed to find the value of the horizontal function by using limit properties for rational functions:
y = 8 / 5
The horizontal asymptote of the rational function y = (8 · x² + 7 · x - 5) / (5 · x² + 2 · x + 6) is y = 8 / 5.
