A banner maker was asked to redesign a squarebanner by increasing the width by 4 feet anddecreasing the length by 2 feet. The total area of thenew banner was 91 square feet.What was the length of the side of the original squarebanner?
Let:
x = original sides.
x + 4 = new width
x - 2 = new feet
So:
(x + 4)(x - 2) = 91
x² - 2x + 4x - 8 - 91 = 0
x² + 2x - 99 = 0
Factoring:
(x + 11)(x - 9) = 0
x = -11 (the lenght can't be negative so this answer is not valid)
x = 9 ft
A watermelon is placed on a digital scale. The scale reads 10.5. What could units be?
The units of weight of watermelon on the digital scale could be kilogram, gram and pounds.
According to the question,
We have the following information:
A watermelon is placed on a digital scale. The scale reads 10.5.
We know that there are several units of measurements for every physical quantity. For example, the units for measuring length are kilometers, meters, centimeters, feet, inches and many more.
In the same way, there are many units for measurements of weight. However, in most of the cases for the weight on a digital scale, it can be kilogram, gram or pound.
So, it could 10.5 kg or 10.5 g or 10.5 pounds.
Hence, the units of the weight of watermelon on the digital scale could be kilogram, gram and pounds.

A line passes through the point (−8, – 7) and has a slope of
-5/4
Write an equation in point-slope form for this line.
The equation in the point-slope form of the line is -7 = -5/4x -8.
What do we mean by point-slope form?One of the three forms we can use to express a straight line is the point-slope form, also referred to as the point-gradient form.
This form is helpful since it allows us to find the equation of the line by only knowing the slope and one point along the line.
The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.
So, the point-slope form is:
The equation of the point-slope form: y = MX + b
Where y is the y coordinate and b is the x coordinate and m is the slope.
Now, get the point-slope form as follows:
y = MX + b
-7 = -5/4x -8
Therefore, the equation in the point-slope form of the line is -7 = -5/4x -8.

if dyllan makes 7 out of 10 free throws on any given day what is the probability he will make his next free throw? ( write your answers as a precent.)
Answer:
70%
Explanation:
The probability can be calculated as the number of free throws that Dylan makes divided by the total number of free throws.
So, if Dylan makes 7 out of 10 free throws, the probability can be calculated as:
[tex]P=\frac{7}{10}=0.7[/tex]Then, to know the probability as a percent, we need to multiply 0.7 by 100% to get:
P = 0.7 x 100% = 70%
Therefore, the answer is 70%

Subtraction:
Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

x₁ = 15 y₁= 150
x₂ = 25 y₂ = 130
[tex]\text{Slope(m)}=\frac{130-150}{25-15}[/tex][tex]=\frac{-20}{10}[/tex][tex]=-2[/tex]Next, is to find the intercept.
Substitute x=15 y=150 and m=-2 into y=mx + b and solve for b
That is;
150 = 15(-2) + b
150 = -30 + b
Add 30 to both-side of he equation

The probability of winning $600 or less if you play the game 10 times, assuming that each game is independent IS 0.5630.
Define binomial distribution.A popular probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters. It totals the number of trials when each trial has an equal chance of producing a particular result. The probability of success raised to the power of the number of successes and the probability of failure raised to the power of the difference between the number of successes and the number of trials are multiplied to create the binomial distribution.
Given,
Cash prize = $100
Probability of winning the game = 0.7
Using binomial distribution,
P(4 ≤X≤ 6) = P( X = 4) + P( X = 5) + P( X = 6)
P( 4 ≤ X ≤ 6)
= 1/4(0.6)⁴(0.4)⁴ + 10/5 (0.6)⁵(0.4)⁵ + 10/6 (0.6)⁶(0.4)⁶

What is the height, x, of the equilateral triangle shown?
an equilateral triangle with the angles labeled as 60 degrees and a side length of 10 inches, the height labeled as x
Answer:
x = 5√3
Step-by-step explanation:
We will use the Pythagorean theorem with a and b as the lengths of the legs, and c as the length of the hypotenuse.
a² + b² = c²
We need two of the three lengths of a, b, and c, so we can find the third length.
The height divides the equilateral triangle into two right triangles.
Look at one of the right triangles.
One leg is half the side of the triangle.
a = 10/2 = 5
One leg is the height.
b = x
The hypotenuse is the side of the equilateral triangle.
c = 10
a² + b² = c²
5² + x² = 10²
25 + x² = 100
x² = 75
x = √75
x = 5√3
Answer: b
Step-by-step explanation:
find the value(s) of c guaranteed by the Mean Value Theorem for Integrals for the function over the given interval.
Remember that
If f is continuous over [a,b] and differentiable over (a,b), then there exists c∈(a,b) such that
[tex]f^{\prime}(c)=\frac{f(b)-f(a)}{b-a}[/tex]In this problem, we have the function
[tex]f(x)=\frac{9}{x^3}[/tex]over the interval [1,3]

f(a)=f(1)=9/(1)^3=9
f(b)=f(3)=9/(3)^3=1/3

Based on the given function,
a) The price that yields the maximum profit is $20.
b) The maximum profit is $6,050
Function
Function defines the relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.
Given,
A rock club's profit from booking local bands depends on the ticket price. Using past receipts, the owners find that the profit p can be modeled by the function p = -15t² + 600t + 50, where t represents the ticket price in dollars.
Here we need to find the price that yields maximum profit and the amount of maximum profit.
In order to find the price that yield the maximum profit, we have to find the value of t, that can be obtained by using the formula,
t = -b/2a
According to the given function the values of a = -15 and the value of b = 600
Apply these values on the given function then we get,
t = -600/ 2(-15)
t = -600/-30
t = 20
Therefore, the price that yields the maximum profit is $20.
Now, we need to find the maximum profit, by apply the value of t as 20 in the given function then we get,
p = -15(20)² + 600(20) + 50
P = -15(400) + 12000 + 50
p = -6000 + 12000 + 50
p = 6000 + 50
