Which of the following capital letters results in the same letter over again when reflected about a
horizontal line? (1 point)
Ο:Α
O:Y
O:S
O:D
Answer: D
Step-by-step explanation:
When D is reflected over a horizontal line (think of it as a mirror on the ground with D on top of it), the reflection will show the letter D in the same way all over again.

Awnser:
1/2 as m, and -3 as b
Step-by-step explanation:
To find the equation of any line, you use the formula: mx+b=y, where m is the slope, y is the y coordinate, b is the y intercept, and x is the x coordinate. However, it only asks for b and m.
You'll need to first find 2 points.
I chose: (6,0) and (0,-3).
The formula to find the slope is: y2-y1/x2-x1.
0-(-3)/6-0
0+3/6
3/6
1/2
Now we need to find the y intercept. However, the graph already tells you what it is. The y intercept always has to have 0 as x.
So the awnser is 1/2 as m, and -3 as b.

During a 60-minute period, a traffic engineer counted 66 trucks and cars that crossed a bridge. The ratio of trucks to cars that travel across the bridge is usually 3:8. The equation 3 8 = t 66 − t 3 8 = t 66 − t can be used to predict the number of trucks, t, the engineer should have counted. How many trucks should the engineer have counted?
Answer:
18
Step-by-step explanation:
t = Number of trucks counted
c = Number of cars
Ratio of trucks to cars = [tex]\dfrac{t}{c}=\dfrac{3}{8}[/tex]
Total number of cars and truck = 66
[tex]t+c=66[/tex]
Divide the left and right side by the number of cars
[tex]\dfrac{t+c}{c}=\dfrac{66}{c}\\\Rightarrow \dfrac{t}{c}+1=\dfrac{66}{c}\\\Rightarrow \dfrac{3}{8}+1=\dfrac{66}{c}\\\Rightarrow \dfrac{11}{8}=\dfrac{66}{c}\\\Rightarrow c=66\times \dfrac{8}{11}\\\Rightarrow c=48[/tex]
Total number of cars is 48
so
[tex]t=66-c\\\Rightarrow t=66-48\\\Rightarrow t=18[/tex]
Total number of trucks counted is 18.

what is the value of the ratio 4:5
Answer:
You might need to be more specific, it could be 4 puppies to 5 dogs, or 4 apples to 5 oranges or 4 cups of flour to 5 cups of flour.
Step-by-step explanation:
The value of 4:5 is 4 for every 5 like 4 cups of sugar for every 5 cups of flour
The simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that the ratio is 4:5.
To convert mixed numbers into improper fractions, when A is the numerator or B is the denominator,
If either A or B is a decimal number, multiply both of their values by the same factor of 10, which will remove all decimal places.
If one value is a whole number and the other is a fraction, you should try to reduce the fraction to a whole number or convert the whole number to a fraction by giving it a denominator of 1.
= 4 / 5
We have to apply the division operation in which we have to divide the number 4 by 5 in order to obtain the improper fraction values as,
=0.8
Thus, the simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.

A number line goes from negative 10 to positive 10. An open circle appears at positive 5. The number line is shaded from positive 5 toward positive 10.
Answer:
After solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]
Option B is correct.
Step-by-step explanation:
We are given compound inequality: [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex]
We will first solve the inequalities to find the value of x, then will draw the graph.
[tex]1.5x-1>6.5 \ or \ 7x+3<-25\\1.5x-1+1>6.5+1 \ or \ 7x+3-3<-25-3\\1.5x>7.5 \ or \ 7x<-28\\x>\frac{7.5}{1.5} \ or \ x<\frac{-28}{7}\\x>5 \ or \ x< -4[/tex]
So, after solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]
Now, the number line will be as shown in figure.
The description as given in options is:
A number line goes from negative 10 to positive 10. An open circle appears at negative 4 and positive 5. The number line is shaded from negative 4 toward negative 10. The number line is also shaded from positive 5 toward positive 10.
so, Option B is correct.

Heres a set of data 2.4, 1.6, 3.2, 0.3, 1.5 each peice of data is increases by 10, what is the mean? each new peice of data is doubles, whats the new mean?
Step-by-step explanation:
Mean is the ratio of the sum of the sample data to the total sample size.
1) Given the set of data 2.4, 1.6, 3.2, 0.3, 1.5, if each piece of data is increases by 10, the new data's will be;
(10+2.4), (10+1.6), (10+3.2), (10+0.3), (10+1.5)
sum of the new data's = 59
Sample size = 5
Mean = 59/5
Mean = 11.8
Hence if the price of data is increases by 10, its new mean will be 11.8
2) If each new piece of data is doubles, the new set of data will be;
2(2.4), 2(1.6), 2(3.2), 2(0.3), 2(1.5)
= 4.8, 3.2, 6.4, 0.6, 3.0
Sum of new data = 4.8+3.2+6.4+0.6+3.0
Sum of new data = 18
sample size = 5
Mean = 18/5
Mean = 3.6
Hence the new mean if the data were doubles is 3.6
What is the image point of (-3,3) after the transformation R180° 0 T-3, -4?
Answer:
Image point → (6, 1)
Step-by-step explanation:
Given point → (-3, 3)
Transformation to be done → [tex]R_{180}0T_{-3,-4}[/tex]
Transformations to be done,
Step - (1). Translation of the given by 3 units left and 4 units down.
Step - (2). Followed by the rotation counterclockwise 180° about the origin.
Rule for step (1),
(x, y) → (x - 3, y - 4)
By this rule,
(-3, 3) → [(-3 - 3), (3 - 4)]
→ (-6, -1)
Rule for step -2,
(x, y) → (-x, -y)
(-6, -1) → (6, 1)
Therefore, following these two steps coordinates of the image point → (6, 1)

Answer:
Zack is correct
Step-by-step explanation:
when we plot out all the points we see that not all sides are the same length, which is techinally defines a square. Because of the different sides lengths we know it is a rhombus.

What is Distance Formula?In a Cartesian plane there are two points P(a, b) and Q(c, d) then the distance between two points
PQ = √(c- a)² + (d- b)²
We have the coordinates F(2, 2) O(5, -2) U(9, 1) and R(6, 5).
Now using Distance Formula
FO = √(-2 - 2)² + (5- 2)² = √16 + 9 = √25 = 5 unit
OU = √(1 + 2)² + (9-5)² = √9 + 16 = √25 =5 unit
UR = 5 unit
RF = 5 unit
and, FU = √(1 -2)² + (9- 2)² = √1 + 49 = √50 = 5√2
OR = √(5+2)² + (6-5)² = √49 +1 = 5√2
So, the given figure is square because the length of Diagonal are equal.

FREE BRAINLY! What is the equation of the line perpendicular to the line y = -3 and passing through the point (2, -1)?
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
We want the equation of the line perpendicular to y=-3.
Notice that y=-3 is a horizontal line.
Therefore, in order to be perpendicular, our new equation must be vertical.
We know that it must pass through the point (2, -1).
Since it must be vertical, it must pass through the x-coordinate.
Therefore, our line must be:
[tex]x=2[/tex]
It passes through (2, -1) and is a vertical line, so it’s perpendicular to y=-3.

You have the option to deposit $6500 into an account that pays 3.25% interest, compounded quarterly OR to deposit your money into an account that pays the same interest rate but compounds continuously. Which option yields you more money after 5 years and how much more?
OPTIONS:
Compounded quarterly, $4809.13
Compounded quarterly, $416.23
Compounded continuously, $5.02
Compounded continuously, $878.52
9514 1404 393
Answer:
Compounded continuously, $5,02
Step-by-step explanation:
Compounded quarterly, the amount in the account will be ...
A = 6500(1 +.0325/4)^(4·5) ≈ 7641.89
Compounded continuously, the amount in the account will be ...
A = 6500e^(.0325·5) = 7646.91
So, the account compounding continuously has the higher yield, by the amount of ...
$7646.91 -7641.89 = $5.02
