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

Earth is approximately 9.3 × 107 miles from the sun. Saturn is approximately 8.87 × 108 miles from the sun. About how much farther is Saturn from the sun than Earth is? A. 7.94 × 107 miles B. 7.94 × 108 miles C. 4.3 × 107 miles D. 4.3 × 108 miles
Answer:
B. 7.94 × 10^8 miles
Step-by-step explanation:
Given that
Earth is approximately 9.3 × 107 miles from the sun.
Saturn is approximately 8.87 × 108 miles from the sun.
We need to find out how much farther is saturn from the sun than earth is
So,
Earth - Sun = 9.3 × 10^7 miles
Saturn - Sun = 8.87 × 10^8 miles
Now
= 8.87 × 10^8 - 9.3 × 10^7
= 88.7 × 10^7 - 9.3 × 10^7
= 79.4 × 10^7
= 7.94 × 10 ^8
= 794,000,000 miles
Hence, saturn is 7.94 × 10^8 miles farther from Sun than Earth is
Shen made $25,000 in taxable income last year.
Suppose the income tax rate is 10% for the first $7000 plus 15% for the amount over $7000.
How much must Shen pay in income tax for last year?
Answer:
3400
Step-by-step explanation:
25000
- 7000 x .10= 700 calculate 10% tax
——————
=18000 x .15 =2700 calculate tax over 7000 at 15%
total tax. = 3400

Someone plz help me giving brainliest
Answer:
B. 5 2/5
Step-by-step explanation:
Use the long division solution to convert the original fraction ( 27/ 5 ) to a mixed number. The whole number portion of the mixed number will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction ( 5 ) , and the fraction portion of the mixed number will be the remainder of the original fraction division ( 2 ) over the denominator of the original fraction ( 5 )

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

I NEED ANSWERS SOON PLS!!!
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

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.

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.

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

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.
