Answer:
7 strips
Step-by-step explanation:
One way we can solve this is through guess and check. Let's start with 4 strips. If Joe's grandma makes 4 strips, she will have 0.75*4 = 3.00 yards of fabric. That's a really low amount of fabric. Let's double that to 8, where Joe's grandma would need 0.75*8 = 6.00 yards of fabric. That's really close! Let's remove one strip. 0.75*7 = 5.25 yards of fabric. Perfect! Joe's grandma can cut exactly 7 strips

The question is incomplete. Here is the complete question.
Lenox ironed 1/4 of the shirts over the weekend. She plans to split the remainder of the work equally over the next 5 evenings. What fraction of the shirts will Lenox iron each day after school?
Answer:
3/20
Step-by-step explanation:
Lenox ironed 1/4 of the shirts during the weekend
She plans to split the remaining work equally over the next five evenings
The first step is to calculate the number of shirts that will be left to iron
= 1-1/4
= 3/4
Therefore the fraction of the shirts that Lenox will iron each day after school can be calculated as follows
= 3/4 /5
= 3/4 × 1/5
= 3/20
Hence the fraction of shirts that Lenox will iron each day after school is 3/20

Step-by-step explanation:We know that,A function of degree 2 is called a quadratic function.For eg :- 3y² - 8y + 5 , x² + 5x - \(\frac{1}{2}\) etc.1. y = x² + 2 Yes, y = x² + 2 is a quadratic function because its degree is 2.2. y = 2x - 10No, y = 2x - 10 is not a quadratic function because it is a linear function.3. y = 9 - 2x²Yes, y = 9 - 2x² is a quadratic function because its degree is 2.4. y = \({2}^{x}\) + 2No, y = \({2}^{x}\) + 2 is not a quadratic function because it is a exponential function.5. y = 3x² + x³ + 2No, y = 3x² + x³ + 2 is not a quadratic function because it is a cubic function.6. y = \({2}^{x}\) + 3x + 2No, y = \({2}^{x}\) + 3x + 2 is not a quadratic function because it is a exponential function + a function of one degree.7. y = 2x²Yes, y = 2x² is a quadratic function because its degree is 2.8. y = (x - 2)(x + 4)First of all we can solved the function
We using the identity,
(x + a)(x + b) = x² + (a + b)x + ab
(x - 2)(x + 4)
= x² + (-2 + 4)x + (-2)(4)
= x² + 2x - 8
Yes, y = (x - 2)(x + 4) that is x² + 2x - 8 is a quadratic function because its degree is 2.9. 0 = (x - 3)(x + 3) + x² - yFirst of all we can solved the function
We using the identity,
(a + b)(a - b) = a² - b²
(x - 3)(x + 3) + x² - y
= x² - 3² + x² - y
= x² - 9 + x² - y
= x² + x² - y - 9
= 2x² - y - 9
Yes, 0 = (x - 3)(x + 3) + x² - y that is 2x²-y-9 is a quadratic function because its degree is 2.10. 3x³ + y - 2x = 0No, 3x³ + y - 2x = 0 is not a quadratic function because it is a cubic function.Express the following situation a a funstion: the population of a school is 800 and is decreasing at a rate of 2% per year

From a sample with n=36, the mean duration of a geyser's eruptions is 3. 68 minutes and the standard deviation is 0. 89 minutes. Using Chebychev's Theorem, determine at least how many of the eruptions lasted between 1. 9 and 5. 46 minutes
At least 25 of the eruptions lasted between 1.9 and 5.46 minutes.
According to Chebychev's Theorem, at least 1 - 1/k^2 of the data values will fall within k standard deviations of the mean. In this case, we want to find at least how many of the eruptions lasted between 1.9 and 5.46 minutes. This range is 1.78 standard deviations from the mean on either side (1.78 = (5.46 - 3.68)/0.89 = (3.68 - 1.9)/0.89). So, k = 1.78.
Plugging this value into Chebychev's Theorem, we get:
At least 1 - 1/k^2 = 1 - 1/1.78^2 = 1 - 1/3.1684 = 0.6846 or 68.46% of the data values will fall within this range.
Since we have a sample size of n=36, we can multiply this percentage by the sample size to find the minimum number of eruptions that lasted between 1.9 and 5.46 minutes:
0.6846 * 36 = 24.7256
Therefore, at least 25 of the eruptions lasted between 1.9 and 5.46 minutes.

Exercise 2. Let G be a group. Suppose that there exist g, h = G such that gª = = e and g³h = hg³. Prove that gh = hg.
In the given exercise, we are asked to prove that if there exist elements g and h in a group G such that g² = e (identity element) and g³h = hg³, then gh = hg.
To prove that gh = hg, we start by multiplying both sides of the equation g³h = hg³ by g². This gives us g²g³h = g²hg³. Using the property g² = e (identity element), we simplify the equation to g³h = hg³.
Next, we multiply both sides of the equation g³h = hg³ by h. This gives us g³h² = h²g³. Again, using the property g² = e, we simplify the equation to g³ = h²g³.
Now, since g³ = h²g³, we can cancel g³ from both sides of the equation to obtain h² = e. This implies that h is its own inverse.
Finally, we multiply both sides of the equation g³h = hg³ by h on the left and by g on the right. This gives us hgh = hgh, which simplifies to gh = hg.
Therefore, we have proved that if g² = e and g³h = hg³, then gh = hg.

A casserole is removed from a 375oF oven and cools to 190oF after 25 minutes in a room at 68oF. How long (from the time it is a removed from the oven) will it take the casserole to cool to 105oF
Answer:
57.3 minutes
Step-by-step explanation:
We know that the temperature as a function of time of an object is described by the equation:
\(T(t) = T_a + (T_0 - Ta)*e^{-k*t}\)
Where:
k is a constant
Tₐ = room temperature = 68°F
T₀ = initial temperature of the object = 375°F
Replacing these in our equation we will get
T(t) = 68°F + (375°F - 68°F)*e^{-k*t} = 68°F + (307°F)*e^{-k*t}
And we know that after 25 minutes, at t = 25min, the temperature of the casserole is 190°F
then:
T(25min) = 190°F = 68°F + (307°F)*e^{-k*25 min}
Now we can solve this for k:
190°F = 68°F + (307°F)*e^{-k*25 min}
190°F - 68°F = (307°F)*e^{-k*25 min}
(122°F)/(307°F) = e^{-k*25 min}
Now we can apply the natural logarithm in both sides:
Ln( 122/307) = Ln(e^{-k*25 min}) = -k*25min
Ln( 122/307)/(-25 min) = k = 0.0369 min^-1
Then the temperature equation is:
T(t) = 68°F + (307°F)*e^{-0.0369 min^-1*t}
Now we want to find the value of t such that:
T(t) = 105°F = 68°F + (307°F)*e^{-0.0369 min^-1*t}
We can solve this in the same way:
105°F - 68°F = (307°F)*e^{-0.0369 min^-1*t}
37°F = (307°F)*e^{-0.0369 min^-1*t}
(37°F)/(307°F) = e^{-0.0369 min^-1*t}
Ln( 37/307) = -0.0369 min^-1*t
Ln( 37/307)/( -0.0369 min^-1 ) = 57.3 min
So after 57.3 minutes, the temperature of the casserrole will be 105°F

Given secant of theta is equal to the square root of 6 over 2 comma what is cos?
The value of cos θ is equal to 1/3 when sec θ= √6/2.
Since we are given the value of secant of theta, we can use the relationship between secant and cosine to find the value of cosine of theta.
Let's start by recalling the definitions of secant and cosine functions. The secant of an angle is defined as the reciprocal of the cosine of that angle.
In other words, secθ = 1/cosθ
Conversely, the cosine of an angle is defined as the reciprocal of the secant of that angle.
cosθ = 1/secθ
We are given that secθ= √6/2
We can use this value to find cosθ= 1/secθ
cosθ = 1 / (√6/2)
To simplify this expression, we can multiply both the numerator and denominator by 2/sqrt(6).
cosθ = ((2/√6) / (√6/2) * (2/√6))
cosθ = (2/√6) / 1
cosθ = (2/√6 * √6/√6)
cosθ = 2/6 = 1/3
Therefore, the value of cosθ is equal to 1/3 when secθ = sqrt(6)/2.

The number of seconds will it take the ball to hit the ground will be 2.078 seconds.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
For example, 3x² + 6x + 8 = 0 here x has the highest term as 2 and the coefficient of x² is not zero.
As per the given,
h(t)=-16t² + 14t + 40
The time when the ball hit the ground h(t) = 0
-16t² + 14t + 40 = 0
-8t² + 7t + 20 = 0
8t² - 7t - 20 = 0
t = (7 ± 26.25)16
t = 2.078 seconds
Since time can never be negative thus, 2.078 seconds will be correct.

The difference of the same side interior angles of two parrelels lines is 50 degrees find all angles
Answer:
Angle 1 = 115 degrees
Angle 2 = 65 degrees
Step-by-step explanation:
Angle 1: Same-side interior angle of Line 1
Angle 2: Same-side interior angle of Line 2
We know that the difference between the angles is 50 degrees. Since the angles are supplementary, we can write the equation:
Angle 1 + Angle 2 = 180
Now, we need to express the difference between the angles in terms of Angle 1 or Angle 2. We can choose either angle, so let's express it in terms of Angle 1:
Angle 1 - Angle 2 = 50
We can rewrite this equation as:
Angle 1 = 50 + Angle 2
Now substitute this expression for Angle 1 into the first equation:
(50 + Angle 2) + Angle 2 = 180
Combine like terms:
2Angle 2 + 50 = 180
Subtract 50 from both sides:
2Angle 2 = 130
Divide by 2:
Angle 2 = 65
Now substitute this value back into the equation for Angle 1:
Angle 1 = 50 + Angle 2
Angle 1 = 50 + 65
Angle 1 = 115
Therefore, the angles are as follows:
Angle 1 = 115 degrees
Angle 2 = 65 degrees
