Answer:
She gives 16 ounces to her neighbor
Step-by-step explanation:
How much did you use to make sauce
6 * 3/4 = 18/4 =9/2 = 4.5 lbs
That leaves 6-4.5 = 1.5 lbs
She give 2/3 of this to her neighbor
1.5 * 2/3
Changing the decimal to a fraction
3/2 * 2/3 = 1
She gives 1 pound to her neighbor, but we want it in ounces
16 ounces equals 1 pound
She gives 16 ounces to her neighbor
For the expression 5x?y3 + xy2 + 8 to be a trinomial with a degree of 5, the missing exponent on the x-term must be
.
Answer:
2
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent of the variable within the expression
y³ is of degree 3
xy² is of degree 1 + 2 = 3 ← sum the exponents of the 2 variables
Thus x²y³ is of degree 2 + 3 = 5
For the expression 5x?y³ + xy² + 8 to be a trinomial with a degree of 5, then the missing exponent of the x term must be 2.

A mirror selling for $98.00, marked up 30% on cost.
M=$
C=$
Answer:
M = $22.62
C = $75.38
Step-by-step explanation:
Selling Price = $98
Markup = 30%
Selling Price = 100 + 30 = 130%
130% = $98
1% = 98/130
Markup
= 98/130 x 30
= $22.62
Cost Price
= 98/130 x 100
= $75.38
Which number is an irrational number?
A) √100
B) 1/8
C) - 2.2675
D) ∛16
For this case we have by definition, that an irrational number is a number that can not be expressed as a fraction \ frac {a} {b}, where a and b are integers and b is different from zero.
A) [tex]\sqrt {100} = 10[/tex], it is rational
B)[tex]\frac {1} {8}[/tex], it is rational
C) [tex]-2.2675[/tex], it is rational
D) [tex]\sqrt [3] {16},[/tex] it is not rational.
Answer:
Option D
The only option that represents an irrational number is D) ∛16.
An irrational number is a number that cannot be expressed as a fraction (ratio) of two integers and has an infinite decimal representation without any repeating pattern.
Let's analyze each option:
A) √100:
The square root of 100 is 10, which is a rational number. It can be expressed as the fraction 10/1.
Therefore, option A) is a rational number.
B) 1/8:
The fraction 1/8 can be expressed as a ratio of two integers. It is equal to 0.125 in decimal form.
Since the decimal representation terminates after a finite number of decimal places, option B) is not an irrational number.
C) - 2.2675:
The number -2.2675 is a decimal number, but it is not an irrational number.
It can be expressed as a rational number by writing it as a fraction. Hence, option C) is not an irrational number.
D) ∛16:
The symbol ∛ represents the cube root. The cube root of 16 is approximately 2.5198.
This number is an irrational number because it cannot be expressed as a fraction of two integers, and its decimal representation continues indefinitely without a repeating pattern.
In summary, the only option that represents an irrational number is D) ∛16.

The length of a rectangle is 2 inches more than the width. If the diagonal is radical 20 inches, find the area of the rectangle.
A) 4 in^2
B) 8 in^2
C) 16 in^2
D) 32 in^2
Answer:
B. 8 in^2.
Step-by-step explanation:
Let the width be x inches, then the length = x + 2 inches.
So by The Pythagoras theorem:
(√20)^2 = x^2 + (x + 2)^2
x^2 + x^2 + 4x + 4 = 20
2x^2 + 4x - 16 = 0
x^2 + 2x - 8 = 0
(x + 4)(x - 2) = 0
x = 2, -4 (we ignore the negative so x = 2)
So the area = 2 * (2 + 2)
= 8 in^2.
Answer:
B
Step-by-step explanation:
L = W + 2
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
(W + 2)2 + W2 = [tex]\sqrt{20} ^{2[/tex]
2[tex]w^{2}[/tex] + 4W + 4 = 20
2[tex]w^{2}[/tex] + 4W − 16 = 0
W = 2 or W = −4
And,
L = W + 2
L = 2 + 2
L = 4
Therefore,
A = LW = (4)(2) = 8
If your invest $150 at 7% interest compounded annually,in how many years will you have $400?. Give your answer of the nearest tenth of a year?
Answer:
14.5 years.
Step-by-step explanation:
Given that you invest $150 at 7% interest compounded annually. Now we need to find about in how many years will you have $400. Then round the answer ot the nearest tenth of a year.
So plug the given values into compound interest formula.
[tex]A=P\left(1+r\right)^t[/tex]
[tex]400=150\left(1+0.07\right)^t[/tex]
[tex]\frac{400}{150}=\left(1+0.07\right)^t[/tex]
[tex]\ln\left(\frac{400}{150}\right)=\ln\left(1+0.07\right)^t[/tex]
[tex]\ln\left(\frac{400}{150}\right)=\ln\left(1.07\right)^t[/tex]
[tex]\ln\left(\frac{400}{150}\right)=t\cdot\ln\left(1.07\right)[/tex]
[tex]\frac{\ln\left(\frac{400}{150}\right)}{\ln\left(1.07\right)}=t[/tex]
[tex]14.4967313882=t[/tex]

what is the solution to the equation x/2-4=6
Answer
x = 20
Explanation
Multiply the entire equation by 2 to get rid of the fraction.
x/2 * 2 = x
-4 * 2 = -8
6 * 2 = 12
Now, we have:
x - 8 = 12
To complete, add 8 to both sides
x = 20
For this case we must find the value of "x" of the following equation:
[tex]\frac {x} {2} -4 = 6[/tex]
So:
We add 4 sides of the equation:
[tex]\frac {x} {2} = 6 + 4\\\frac {x} {2} = 10[/tex]
We multiply by 2 on both sides of the equation:
[tex]x = 20[/tex]
Thus, the value of the variable x is 20
Answer:
[tex]x = 20[/tex]
Find the values of x in this equation: x – 15 x = 2 . A. -7, 3 B. -5, 2 C. -7, 5 D. -2, 5 E. -3, 5
Answer:
Step-by-step explanation:
The given expression is x- [tex]\frac{15}{x}[/tex] = 2
and we have to solve this for the value of x,
( x- [tex]\frac{15}{x}[/tex]) = (2)
[tex]\frac{x^{2}-15 }{x} =2[/tex]
x² - 15 = 2x
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x ( x-5 ) + 3(x - 5) = 0
( x+3 )( x-5 ) = 0
( x+3) = 0
x = -3
or ( x- 5 ) = 0
x = 5
Therefore, x = -3 and 5 will be the solution.

What is the length of segment AB?
A coordinate plane is shown. Point A is located at 0, 12, and point B is located at 5, 0. The two points are connected by a line segment.
Answer:
length of segment AB is 13
OR
AB = 13
Step-by-step explanation:
Use the Pythagorean Theorem with c being the length of segment AB.
a^2 + b^2 = c^2
5^2 + 12^2 = c^2
169 = c ^2 (square root both sides to get c by itself)
13 = c

Here, r = d/2 = 3 in, and h = 8 in.
V = π (3 in)² (8 in)
V = 72π in³

[tex]T.S.A = 2\pi \: r(r + h)[/tex]
The height of the cylinder is , h=10in.
The radius of the cylinder is, r=5in.

To find the polynomial of degree 3 with real coefficients and specific zeros and y-intercept, we use the fact that complex zeros occur in conjugate pairs. We can express the polynomial as f(x) = a(x-3)(x-(1+3i))(x-(1-3i)), where a is a constant. By plugging in the y-intercept value, we can solve for the constant a.
Explanation:To find the polynomial with degree 3 and real coefficients that has a y-intercept of 60 and zeros 3 and 1+3i, we can use the fact that complex zeros occur in conjugate pairs. Given that 1+3i is a zero, its conjugate 1-3i is also a zero. Therefore, the polynomial can be expressed as f(x) = a(x-3)(x-(1+3i))(x-(1-3i)), where a is a constant.
Since the polynomial has a y-intercept of 60, we know that f(0) = 60. Plugging in x=0, we can solve for the constant a:
f(0) = a(0-3)(0-(1+3i))(0-(1-3i)) = 60
Since the constant a is the only unknown variable, we can solve for it:
-3*(1+3i)*(1-3i) = 60/a
-3*(1-9i^2) = 60/a
12 = 60/a
a = 5
Therefore, the polynomial f(x) = 5(x-3)(x-(1+3i))(x-(1-3i)) has the desired properties.
