Step-by-step explanation:
Find the values of a and b if,
ab=12 and a+b=7
Answer:
Given
Ab = 12
A+b = 7
As a + b = 7,
A and b must be less than 7
A =6
B =2
Ab = 12
6 x 2 = 12

How many more cubic inches are in the volume of a cylinder with a diameter of 12 inches and a height of 13 inches than in the volume of a cylinder with a diameter of 10 inches and a height of 11 inches?
Answer:
Approx. 606.02 cubic inches more.
Step-by-step explanation:
[tex]Volume=\pi *(\frac{diameter}{2})^2*height[/tex]
First, let's find the volume of the first cylinder (diameter=12, height=13).
[tex]V=\pi * (\frac{12}{2})^2 * 13\\V=\pi * (6)^2 * 13\\V=\pi * 36 * 13\\V=3.14*36*13\\V=113.04*13\\V=1469.52 in^3[/tex]
Now let's find the volume of the second cylinder (d=10, h=11).
[tex]V_{2}=\pi * (\frac{10}{2})^2*11\\V_{2}=\pi * (5)^2*11\\V_{2}=\pi * 25 * 11\\V_{2}=3.14*25*11\\V_{2}=78.5*11\\V_{2}=863.5in^3[/tex]
Lastly, we can subtract the volume of the second cylinder from the volume of the first cylinder.
This gets us a solution of 606.02 cubic inches.

A man stands on his balcony, 140 feet above the ground. He looks at the ground, with his sight line forming an angle of
75 with the building, and sees a bus stop. The function d=140 sec 0 models the distance from the man to any object given
his angle of sight 0. How far is the bus stop from the man? Round your answer to the nearest foot.
The bus at an angle of sight of 75 degrees from the man is at a distance of 541 feet
How to determine the distance?The distance function is given as:
d = 140 sec(x)
Where x represents the angle of sight.
In this case,
x = 75
So, we have:
d = 140 sec(75)
Evaluate the product
d = 541
Hence, the bus at an angle of sight of 75 degrees from the man is at a distance of 541 feet

. The Flower Bouquet flower shop charges $1.50 for placing an order and $0.50 for each flower ordered. Which equation could be used to find n,the number of flowers purchased if the total bill was $9. (1 point)
A $9 = (0.50 + 1.50)n
B 0.50n + 1.50 = $9
C $9 = 50n + 1.50
D 0.50 n + 1.50n = $9
The equation that could be used to find the number of flowers purchased if the total bill was $9 is:0.50n + 1.50 = $9.
Since each flower costs $0.50, multiplying the cost per flower by the number of flowers (n) gives the total cost of the flowers then 0.50n represents the cost of the flowers.
and, 1.50 represents the fixed cost for placing the order.
and $9 represents the total bill, which includes the cost of the flowers and the fixed cost.
By adding the cost of the flowers (0.50n) to the fixed cost (1.50), the equation sets the total bill equal to $9 we get the Equation as
0.50n + 1.50 = $9

(x - 4)(x + 23) = (x + 14)(x - 1) ← expand factors on both sides using FOIL
x² + 19x - 92 = x² + 13x - 14 ( subtract x² from both sides )
19x - 92 = 13x - 14 ( subtract 13x from both sides )
6x - 92 = - 14 ( add 92 to both sides )
6x = 78 ( divide both sides by 6 )

The probability that Wesley draws an ace or a jack is 0.154 and the probability that Wesley draws a number card or a black card is 0.846
The probability of Ace or jackIn a standard deck of cards, we have:
Total = 52
Ace = 4
Jack = 4
Ace and Jack = 0
The probability is then calculated as:
P = P(Ace) +P(Jack) - P(Ace and Jack)
This gives
P = 4/52 + 4/52 - 0/52
Evaluate
P = 0.154
Hence, the probability that Wesley draws an ace or a jack is 0.154
The probability of Number card or black cardIn a standard deck of cards, we have:
Total = 52
Number card = 36
Black = 26
Number card and Black = 18
The probability is then calculated as:
P = P(Number card) +P(Black card) - P(Both)
This gives
P = 36/52 + 26/52 - 18/52
Evaluate
P = 0.846
Hence, the probability that Wesley draws a number card or a black card is 0.846

Which equation represents the line that is parallel to y = -3 and passes through (-1, 6)?
y = __
Answer:
Step-by-step explanation:
We'll look for an equation with the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
A parallel line will have the same slope as the reference line, in this case it is 0, since y = -3 has no x term in it [y is independent of x]. The line we want will have the form y=b, since m is 0. Put the given point, (-1,6) into this equation to find b:
y=b
6=b
The equation of a line parallel to y=-3 is y=6.

Solve for h
h - 3h - 8 = 14
H=?
Answer:
-22
Step-by-step explanation:
h-3h-8=14
-2h=14+8
-2h=22
h=-11
The initial step that must be taken before solving almost any problem is to understand what the problem is asking for us to do and what is provided to us to complete that goal. Looking at the problem statement, we can see that we are being requested to solve for h and we are provided an expression to do so. Let's begin solving the expression by combining like terms.
Combine like terms
[tex]h - 3h - 8 = 14[/tex][tex](h - 3h) - 8 = 14[/tex][tex](- 2h) - 8 = 14[/tex]Just a quick explanation on what combine like terms means, it basically just means to combine the coefficients of the numbers associated with the same variables. Like in this example we can combine h and -3h because they have have the variable h associated with them.
Add 8 to both sides
[tex](- 2h) - 8 = 14[/tex][tex](- 2h) - 8+ 8 = 14 + 8[/tex][tex]- 2h= 22[/tex]Divide both sides by -2
[tex]- 2h= 22[/tex][tex]\frac{- 2h}{-2}= \frac{22}{-2}[/tex][tex]h= \frac{22}{-2}[/tex]Simplify the expression
[tex]h= - \frac{22/2}{2/2}[/tex][tex]h= - \frac{11}{1}[/tex][tex]h= - 11[/tex]Therefore, after completing the steps above we were able to determine that the value of h is equal to -11.

D. If the owner wants to know the number of bottled soft drink sales for which the number of sales below it and above it were equal.
Answer:
A
Step-by-step explanation:
Well automatically we can eliminate B and D because they make no sense whatsoever. So that leaves us with A and C. A is telling us to find the mean so it has to be that one. So, with procces of elimination the answer has to be A. I know this because the owner needs to find an average to see how many bottles he will have sold daily. ;) Your very much welcome
