Answer:
Jaime = 11
Sammy = 44
Step-by-step explanation:
It is given that Sammy is eleven less than five times Jaime's age. Use parameter (S) to represent Sammy's age, and parameter (J) to represent Jaime's age. Form an equation based on this given information:
S = 5J - 11
It is given that the sum of the two girl's ages is (55), use an equation to represent this.
S + J = 55
Substitute in the expression for the value of (S) in terms of (J),
(5J - 11) + J = 55
Simplify,
6J - 11 = 55
Inverse operations,
6J - 11 = 55
6J = 66
J = 11
Backsolve for the value of (S), substitute in the value of (J) into the equation for (S) and solve,
S = 5(J) - 11
S = 5(11) -11
S = 55 - 11
S = 44

Lancelot deposited $5000 each into 2 different savings accounts. Account A earns 8% simple interest. Account B earns 8% interest compounded annually. What is the sum of the balances of both accounts at the end of 6 years?
Answer:
$15,334.37
Step-by-step explanation:
Lancelot deposited $5000 each into 2 different savings accounts.
Step 1- For simple Interest
Amount of money in the account
Account A earns 8% simple interest.
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year.
Solving our equation:
A = 5000(1 + (0.08 × 6)) = 7400
A = $7,400.00
Step 2- For Compounded Interest
Account B earns 8% interest compounded annually.
First, convert R as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 5,000.00(1 + 0.08/1)(1)(6)
A = 5,000.00(1 + 0.08)(6)
A = $7,934.37
The sum of the balances of both accounts at the end of 6 years is calculated as:
$7,934.37 + $7,400.00
=$15,334.37
f(x)= x g(x)=x+1 graph f/g
Answer:
Step-by-step explanation:
x
(f/g)(x) = -----------
x + 1
Notice that x cannot be -1, which would lead to division by zero. Thus, x = -1 is the vertical asymptote. Also notice that if x grows increasingly large, the fraction shown tends towards x/x, or 1, so we know that the horizontal asymptote is y = 1.
Draw a set of x-y axes and graph y = 1 and x = -1. Plot (0, 0). Again, note that the graph of this function never touches/crosses x = -1. So, for (-1, 0) the graph is a curve caught between x = -1 and x = 0 that increases as x increases. For (0, infinity), the graph heads upward at a slow pace and then levels off nearly parallel to y = 1 (the horizontal asymptote).
As x increases from left to right, y starts out slightly greater than y = 1 and then (while still in Quadrant II) curves upward and approaches the vertical asymptote x = -1.

Answer:
100 - 1/20 = 99.95
99.95 - 45 = 54.95
54.95 x 18/100 = 9.891, 54.95 - 9.891 = 45.059
45.059 - 12 = 33.059
33.059 divided by 2.50 = 13.2236, about 13 games

The faces of a fair 6 - sided cube are numbered 1 through 6. What is the probability that a 2 will land face up on the next roll? Give your answer as a fraction in simplest form and the percent.
Answer:
You will have a 1/6 probability of getting a 2 that will land face up on the next roll.
Step-by-step explanation:
There is only one two on the cube, which means you will have 1 chance out of 6 of getting a 2.
Is r = 9 a solution to the inequality below?
72r
yes
no
Submit
Explain how to solve problems like this please
Answer:
No.
Step-by-step explanation:
For the inequality 7 ≥ r, 9 is not a solution. This inequality states that seven is greater than or equal to r, but 7 is not greater than or equal to 9. So this makes 9 not a solution for this inequality.

Calinda is painting the design on her bedroom wall. The large circle has a diameter of 32 inches. To the nearest square inch, how much paint swill she need for the shared reign on
Answer:
804 inches
Step-by-step explanation:
Amount of paint she would need is equal to the area of the circle
Area of a circle = πr²
π = 3.14
r = 32/2 = 16
The diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x 16² = 804 in

A random variable X follows a Binomial distribution; i.E. X ~ B(12, p) with a variance of 1.92. Compute the possible values of p
==================================================
Explanation:
Any binomial distribution has two unique components to it: The number of trials n, and the probability of success p.
We're given n = 12, and we need to find p.
The variance of a binomial probability distribution is given by the formula n*p*(1-p). Plug in n = 12 and set this equal to 1.92
So the equation to solve is 12p*(1-p) = 1.92
Solve for p using a graphing calculator or you could apply the quadratic formula. Either way, you should get the two results of p = 0.2 and p = 0.8
Note that if p = 0.2, then 1-p = 1-0.2 = 0.8, and things flip around when p = 0.8.
Jamie uses exactly 18 inches of dental floss every time she flosses her teeth. The package of dental floss she just bought contains 27 yards. How many times can Jamie floss her teeth with the amount of floss in this package?
Answer:
54 times
Step-by-step explanation:
36 inches = 1 yard
Since there are 27 yards, you multiply 36 by 27 = 972
If you use 18 inches each time, you would divide 972 by 18.
972/18= 54
So, Jamie could flow her teeth 54 times.

The dimensions of a rectangle can be expressed as x−1 and x+5. If the area of the rectangle is 91 square inches, what are the dimensions of the rectangle? Make sure to enter BOTH dimensions.
Answer:
13 x 7
Step-by-step explanation:
area = L x W
91 = (x - 1)(x + 5)
x² + 5x - x - 5 = 91
combine like terms:
x² + 4x - 5 = 91
subtract 91 to each side of the equation:
x² + 4x - 96 = 0
factor:
(x + 12)(x - 8)
x = 8
x - 1 = 7
x + 5 = 13

Rotate an isosceles right triangle around a line that contains the triangle's hypotenuse
Answer:
See attachment 2 for the rotation
Step-by-step explanation:
The question has a missing figure
See attachment 1 for the missing figure of the isosceles right-triangle
Required
Rotate around the hypotenuse
From the attachment, the hypotenuse is along the blue vertical line along the y-axis.
So, when the isosceles triangle is rotated around the hypotenuse, the result of the rotation we get a composite figure that has two congruent solids.
Which is a cone of radius and height equal to half of the hypotenuse
See attachment 2 for the rotation

The terminal side of θ in standard position contains the point (–4, 3). Find the exact values of the six trigonometric functions of θ. (show all of your work) *
Answer:
When we have a rectangular point (x, y), the angle between the x-axis and a ray that connects the origin with this point is given by:
Tan(θ) = y/x.
Cos(θ) = x/(√(x^2 + y^2))
Sin(θ) = y/(√(x^2 + y^2))
So for the point (-4,3) we have:
x = -4
y = 3
√( (-4)^2 + 3^2) = √(16 + 9) = √25 = 5
Then:
Tan(θ) = 3/-4 = -(3/4)
Sin(θ) = 3/5
Cos(θ) = -4/5
And for the other 3 trigonometric functions (the inverses of the 3 above ones) we have:
Ctg(θ) = 1/Tan(θ) = -4/3
Csc(θ) = 1/Sin(θ) = 5/3
Sec(θ) = 1/Cos(θ) = -4/5
