7p + a = 45
Adding these two equations together to get a alone we need to multiply the bottom by -1
7p + 6a = 95
-7p - a = -45
5a = 50
a = 10
Now plugging in a to which ever equation
7p + a = 45
7p + 10 = 45
7p + 35
p = 5

Michael walks 30 meters in 20 seconds. How many meters does he walk per second?
Answers
Answer:
1.5 meters per second
Step-by-step explanation:
30 meters in 20 seconds. U need to "separate" the 30 seconds into 20 parts so u have to divide:
30/20 = 1.5
Answer: 1.5 meters
Step-by-step explanation:
To find how many meters in 1 second we need to make a unit. We'll use fractions in this case...
30 meters ÷ 20 1.5 meters
-------------- = -----------------
20 seconds ÷ 20 1 second
This is a fancy was of saying 1.5 meters per 1 second.
The ocean liner Titanic lies under 12500 feet of water at the bottom of the Atlantic Ocean. (The density of water is 62.4 lb/ft3.)
(a) What is the water pressure at the Titanic? (Give your answer in both pounds per square foot and pounds per square inch.)
I got 780000 lbs/ft^2 which is equal to about 5416.67 lbs/in^2
(b) What is the total force on a circular porthole (window) of diameter 7 feet standing vertically with its center at the depth of the Titanic?
Answers
Answer:
a)[tex]780000 lb/ft^2[/tex]
b)Total force = 30017917.805 lb
Step-by-step explanation:
Depth of titanic = 12500 feet
Density of water =[tex]62.4 lb/ft^3[/tex]
a)Water pressure at the Titanic =[tex]depth \times density = 12500 \times 62.4=780000 lb/ft^2[/tex]
b)
Set up a integral that gives a total force
Diameter = 7 feet
[tex]Radius = \frac{7}{2}\\x^2+y^2=(\frac{7}{2})^2\\r^2+h^2=(\frac{7}{2})^2\\r=\sqrt{(\frac{7}{2})^2-h^2}[/tex]
Rectangular strip area =[tex]2r \Delta h[/tex]
Pressure = 62.4(12500-h)
Force =[tex]Pressure \times Area[/tex]
Force =[tex]62.4(12500-h) \times 2(\sqrt{(\frac{7}{2})^2-h^2}) \Delta h[/tex]
Total force = [tex]\int\limits^{\frac{7}{2}}_{\frac{-7}{2}} {124.8(12500-h)\sqrt{(\frac{7}{2})^2-h^2} \, dh[/tex]
Total force = 30017917.805 lb

Answers
Answer:
1.
Variable: x
Inequality: x ≤ 12
Value that matches: 12
2.
Variable: y
Inequality: y < 66
Value that matches: 60
Step-by-step explanation:
Solving (1):
Let x be the variable
Reading through the question, we have the inequality to be represented by "at most".
At most is used for less than or equal to.
Hence, the expression can be represented by:
x ≤ 12
The range of this inequality is limited to all natural number that do not exceed 12.
Examples are 8, 2, 11, 12
Solving (2):
Let the variable be y
Reading through the question, we have the inequality to be represented by "below".
Below means less than
Hence, the expression can be represented by:
y < 66
The range of this inequality is limited to all number less than 66.
Examples are 65, 1 , 60......

6*3+6*8 and 6(3 + 8).
What is the total area of a Plane figure?The total area of a plane figure refers to the addition of individual area shapes combined in that plane figure.
From the given information, we have two areas that assume the shape of a square.
The office area = 18 square feetThe living room area = 48 square feet.The total area of the two rooms now = 18 + 48 = 66 square feet.
Now, the expressions that better represent the total area of the two rooms can be written as 6*3+6*8 and 6(3 + 8).
