Points P,Q,R,and S are collinear. Point Q is between P and R, R is between Q and S. If PS=25, and PR=19, what is the value of QR
Answer:
13Step-by-step explanation:
The questions is incomplete. Here is the complete question.
Points P,Q,R,and S are collinear. Point Q is between P and R, R is between Q and S where PQ ≈ RS. If PS=25, and PR=19, what is the value of QR
If points P,Q,R,and S are collinear, this means that the four points lies on the same straight line.
If Point Q is between P and R, then PQ+QR = PR ........... 1
Also if R is between Q and S, then QR+RS = QS ...... 2
Given
PS=25
PR=19
RS = PS-PR
RS = 25-19
RS = 6
Since PQ ≈ RS
Hence PQ = RS = 6
From equation 1;
PQ+QR = PR
substituting the resulting values
6+QR = 19
QR = 19-6
QR = 13
Hence the value of QR is 13

Answer:
4+8 = 12 , 6-3 = 3 , 2 x 3 = 6 , 12/6 = 2
the answer is 2
The expression 4 + 8 / 2 x (6 - 3) is equivalent to 16.
What is BOD MAS rule?The Bodmas rule is arranged according to the letters in the acronym BOD MAS, which stand for brackets, order of powers or roots, division, and multiplication. A stands for addition and S for subtraction. According to the BOD MAS rule, mathematical equations containing numerous operators must be resolved in the BOD MAS order, starting from the left.
The given expression is,
4 + 8 / 2 x (6 - 3)
Solve by using BODMAS rule,
4 + 8 / 2 x 3
Further solve,
4 + 4 x 3
4 + 12

0.18 as a fraction simplest form
Answer:
9/50
Step-by-step explanation:
First, convert the decimal into a fraction. In this case, convert .18 to 18/100. Find a common factor between the numerator and denominator, which in this case, would be 2. Divide both the numerator and denominator by 2 to get 9/50. 9/50 can't be simplified further, so this is your answer.
Answer:
[tex]\frac{9}{50}[/tex]
Step-by-step explanation:
0.18 is [tex]\frac{18}{100}[/tex].

G (x) = left-brace (negative 9, negative 5), (negative 4, negative 3), (1, 0), (7, 3), (13, 6), right-brace. f (x) = x + 7; g (x) = x minus 7 2 2-column tables with 4 rows. Table 1 is titled f (x). Column 1 is labeled x with entries 2, 3, 4, 5. Column 2 is labeled y with entries 3, 8, 15, 24. Table 2 is titled g (x). Column 1 is labeled x with entries 5, 4, 3, 2. Column 2 is labeled y with entries 24, 15, 8, 3.

g(x) = {(-9,-5), (-4, -3), (1,0), (7,3), (13,6)}
Yes, this pair is inverse as all points of the functions have inverse values2...................................
f(x) = x + 7 is given
Inverse of f(x) is
x = f'(x) + 7 ⇒ f'(x) = x - 7Since g(x) = x - 7 it is inverse with f(x)
Yes, this pair is inverse as described above3...................................

Step-by-step explanation:
❶ It is irrational because to make it repeating it must be EXACT. In this case it is adding a 0 after every 1. So it'd be irrational since it doesn't have an end.
❷ Irrational because no one knows the end of pi. It doesn't have an ending so therefore irrational.

Carrie sees a dress she wants that usually sells for $109. The dress is on sale at 15% off and sales tax is 6.5%. How much will Carrie need to purchase the dress?
Answer:
$98.67
Step-by-step explanation:
109(.15)= $16.35 You multiply by .15 to find out what 15% of the total (109) is going to be discounted.
109-16.35= 92.65 You subtract the discount from the total to come up with the new total.
92.65(1.065)= 98.67225 =98.67 You take the discounted total, 92.65, and multiply it by 1.065 which represents how you will will be paying for sales tax.

What is the mean of the height 81,88,69,65,87
Answer:
C. 78 cm
Step-by-step explanation:
The mean of any given data set is calculated as sum of all data set divided by the number of data set given.
The data set for the height of Bella's corn given, is 81, 88, 69, 65, 87
Mean height of Bella's corn = [tex] \frac{81 + 88 + 69 + 65 + 87}{5} [/tex]
[tex] mean = \frac{390}{5} [/tex]
[tex] mean = 78 cm [/tex]
You are required to calculate the mean of the height, in other words, the average of the height
The mean of the height is 78
Given height
81, 88, 69, 65, 87
Mean = Total height / number of height
= (81 + 88 + 69 + 65 + 87) / 5
= 390 / 5
= 78
Mean of the height = 78
