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

Answers

Answer:

13

Step-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:

Step-by-step explanation:

To get rid of the coefficient of w, 3/2 in this case, we must divide the entire equation by 3/2, which is the equivalent of multiplying the entire equation by 2/3. Doing this, we get:

3/2w * 2/3 = -20 * 2/3

Step-by-step explanation:

The volume of cube 4x².

What is Volume?

Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.

We have,

Edges of cube as = 4 , x and x.

So, volume of cube

= 4 x (x . x)

= 4 . x²

= 4x²

Column 2 is labeled y with entries 24, 15, 8, 3.

Answer:

The first two pairs of functions are inverse of each other

Step-by-step explanation:

Inverse functions?

1...................................

f(x) = {(-5, -9), (-3, -4), (0,1), (3,7), (6,13)}

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 values

2...................................

f(x) = x + 7 is given

Inverse of f(x) is

x = f'(x) + 7 ⇒ f'(x) = x - 7

Since g(x) = x - 7 it is inverse with f(x)

Yes, this pair is inverse as described above

3...................................

Data of f(x) and g(x)

x = {2, 3, 4, 5}      f(x) = {3, 8, 15, 24}

x = {5, 4, 3, 2}      g(x) = {24, 15, 8, 3}

No, as both functions have same domain and rangeexample is f(2) = 3 and g(2) = 3 as per table

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?

Answers

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.
