Answer:
slope = -1.5
Step-by-step explanation:
A set of three or more points are said to be collinear if they all lie on the same straight line.
We have been given the following collinear set of points;
P(0, 3), Q(2, 0), R(4, -3)
This implies that P, Q, and R lie on the same line.
The slope of a line is defined as; (change in y)/(change in x)
Using the points P and Q, the slope of the line is calculated as;
(0-3)/(2-0) = -3/2 = -1.5
Answer:
-3/2

Step-by-step explanation:
In this question figure of pyramid is attached below the question .
Surface area of the rectangular pyramid :
Area of the Base = Length × Width
= 10 × 2 = 20 cm²
Area of Lateral #1 =
=
= 31.5 cm²
Area of Lateral #2 =
=
= 8 cm²
Surface area of the pyramid = 20 + 2(31.5) + 2(8)
= 20 + 63 + 16
= 99 cm²
Surface area of the pyramid is 99 cm²
Answer:
99cm2
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
L= 3W
Perimeter = 2(l+w) = 40
2(3w+w) = 40
2*4w = 40
8w =40
w = 5
l = 3*5 = 15
An equation is formed when two equal expressions. The cost of serving a pancake will cost $4.25.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that your total bill amount is $11.50. Also, you give a tip of 15% of your bill. Therefore, if the amount of the bill is assumed to be x then the total bill amount can be written as,
Total bill amount = Bill amount + 15% of the bill amount
$11.50 = x + 0.15x
11.50 = 1.15x
x = $11.50 / 1.15
x = $10
Therefore, the bill amount for the food was $10.
The cost of the fruit cup is $1.50, while the order was two servings of Pancakes and a fruit cup. Therefore, if the cost of a serving of pancake is assumed to be 'c'. Then we can write,
Cost of fruitcake + Cost of two pancakes = $10
$1.50 + 2c = $10
2c = $10 - $1.50
2c = $8.5
c = $8.5/2
c = $4.25
Hence, the cost of a serving of pancakes will cost $4.25.
