Mary drilled a hole that is 5/8 inch wide. She has a screw that is 5/6 inch wide. Is the hole wide enough to fit the screw? Explain by comparing the two fractions.
Answer:
nope the screw can't fit in the hole.
Step-by-step explanation:
because 8 is smaller than 6, the pieces of 6 are bigger. If both of the rectangles have 5 pieces colored in, that the screw is bigger that the hole

The total length of wires a b and c is 445 cm wire a is 45 cm longer then wire b and wire b is half as long as wire c how long is wire a
Answer:
[tex]a = 145\ cm[/tex]
Step-by-step explanation:
Given
[tex]a + b + c = 445[/tex]
[tex]a = 45 + b[/tex]
[tex]b = \frac{1}{2}c[/tex]
Required
Determine the length of a
Solve for c in [tex]b = \frac{1}{2}c[/tex]
[tex]2 * b = \frac{1}{2}c * 2[/tex]
[tex]2b = c[/tex]
[tex]c = 2b[/tex]
Substitute [tex]c = 2b[/tex] and [tex]a = 45 + b[/tex] in [tex]a + b + c = 445[/tex]
[tex]a + b + c = 445[/tex]
[tex]45 + b + b + 2b = 445[/tex]
[tex]45 + 4b = 445[/tex]
Solve for 4b
[tex]4b = 445 - 45[/tex]
[tex]4b = 400[/tex]
Solve for b
[tex]b = 400/4[/tex]
[tex]b = 100[/tex]
Recall that: [tex]a = 45 + b[/tex]
[tex]a=45+100[/tex]
[tex]a = 145\ cm[/tex]
A farmer has 5 cartons of eggs for sale. Each carton contains 12 eggs.
if 5/6 of the eggs are brown, what is the total number of eggs that are not brown
Answer:
10 eggs
Step-by-step explanation:
5 cartons multiplied by 12 eggs each equals 60 eggs in total.
Therefore 5/6 would be equal to 50/60 since we multiply the denominator and numerator by 10
As a result 10 of the eggs are not brown

Triangle ABC has two known angles. Angle A measures 55 degrees. Angle B measures 30 degrees. What is the measure of angle C?
Answer:
rotation spins the shape around the origin while a reflection mirrors it across an axis. Two congruent figures are two figures that are Identical but in different locations. Travis is incorrect because when Travis changes the size he changes the shapes from being congruent to being similar. Adjacent angles are angles that share a wall and a vertex. The measure of angle y is 40 degrees. The measure of angle C is 95 degrees.

When you raise an exponential expression to another exponent, you multiply the exponents. We have 8*5 = 40 as the final exponent. The rule is (x^y)^z = x^(y*z). The base stays the same.
Statement A is not true because we should be adding the exponents. The rule is x^y*x^z = x^(y+z). Note how the bases are all the same. We'll use this rule for statement C to show that it is also false.
A similar rule is (x^y)/(x^z) = x^(y-z). We subtract the exponents this time. This rule is used to show that statement D is false.

the mean lifespan is 71.45 years, and the standard deviation is 12.35 years. Mr. Rodriguez would like to know how many days, on average, presidents tend to live beyond their 70th birthday. Find the mean and standard deviation of the transformed data. Note: There are 365 days in a year.
Answer:
Standard deviation, ∂ = 64.21 days
Mean = 429.21 days
Step-by-step explanation:
Given:
Mean lifespan = 71.45 years
Standard deviation = 12.35 years
Standard deviation, ∂ = x - µ / N
Where,
∂ = standard deviation
µ = mean life span
x = size of year
x = 70 years
Standard deviation, ∂ = x - µ / N
= 70 - (71.45 / 12.35)
= 70 - 5.79
= 64.21
Standard deviation, ∂ = 64.21 days
Mean = ∑x + standard deviation
∑x = 365
Mean = ∑x + standard deviation
= 365 + 64.21
= 429.21 days
Mean = 429.21 days

-7k-4K=8-2k-8k
Answer:
-7k-4K=8-2k-8k
-11K = 8-10K (combine like terms)
8 = -11k+10k (move the -10 to combine like term with -11)
8 = -1k
k = 8/-1 (isolate the k to find its value by dividing the 8)
k = -8
How does one find the inverse function of f(x)= [tex]\frac{1}{3x-1}[/tex]
Answer:
[tex]\displaystyle f^{-1}(x)=\frac{1+x}{3x}[/tex]
Step-by-step explanation:
The Inverse of a Function
The procedure to find the inverse of the function is:
* Write the function as a two-variable equation:
[tex]\displaystyle y=\frac{1}{3x-1}[/tex]
* Solve the equation for x.
Multiply by 3x-1
[tex]y(3x-1)=1[/tex]
Divide by y:
[tex]\displaystyle 3x-1=\frac{1}{y}[/tex]
Sum 1:
[tex]\displaystyle 3x=\frac{1}{y}+1[/tex]
Operate the right side:
[tex]\displaystyle 3x=\frac{1+y}{y}[/tex]
Divide by 3:
[tex]\displaystyle x=\frac{1+y}{3y}[/tex]
* Swap the variables:
[tex]\displaystyle y=\frac{1+x}{3x}[/tex]
Write back into function form:
[tex]\boxed{\displaystyle f^{-1}(x)=\frac{1+x}{3x}}[/tex]

At 2 hours before sunset, the temperature is 0°F. At 2 hours after sunset, the temperature is −4°F. Identify the slope, y-intercept, x-intercept, and equation that represents the temperature, y, as it changes over time, x.
Answer:
[tex]Slope = -1[/tex]
[tex]y = -2[/tex] --- y intercept
[tex]x = -2[/tex] ---- x intercept
[tex]y = -x - 2[/tex] --- equation
Step-by-step explanation:
Given
Represent temperature with y and time with x
When
[tex]y = 0F; x = 2hrs\ before\ sunsets[/tex]
[tex]y = -4F; x = 2hrs\ after\ sunset[/tex]
Solving Slope;
[tex]Slope = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]Slope = \frac{-4 - 0}{2 - (-2)}[/tex]
[tex]Slope = \frac{-4 - 0}{2 +2}[/tex]
[tex]Slope = \frac{-4}{4}[/tex]
[tex]Slope = -1[/tex]
Using
[tex]Slope = \frac{y - y_1}{x - x_1}[/tex], we can get the equation
Where
[tex]Slope = -1[/tex]
[tex]x_1 = -2[/tex]
[tex]y_1 = 0[/tex]
This gives:
[tex]-1 = \frac{y - 0}{x -(-2)}[/tex]
[tex]-1 = \frac{y}{x +2}[/tex]
Cross multiply
[tex]y = -x - 2[/tex]
Take x as 0; to solve the y intercept
[tex]y = -0 - 2[/tex]
[tex]y = -2[/tex]
Take y as 0; to solve the x intercept
[tex]0 = -x -2[/tex]
[tex]x = -2[/tex]
Answer:Answer:
--- y intercept

A certain bacteria doubles in number every hour. If there are 5 bacteria

Some atomic processes can result in the emission of an electron from the atom. Electrons emitted in this way can have discrete values of kinetic energy, which depend on the atomic energy levels. The probability that the electron has a particular value depends on interacions within the atom. Suppose a particular atomic process results in three values of the electron kinetic energy: Ψ1 has Ee = 10 eV, with probability 0.2. Ψ2 has Ee = 16 eV, with probability 0.3. Ψ3 has Ee = 34 eV, with probability 0.5. The electron's wave function can be written as a quantum superposition: Ψ = aΨ1 + bΨ2 + cΨ3 What are the magnitudes of a, b, and c?
Answer:
|a| = 0.447
|b| = 0.547
|c| = 0.707
Step-by-step explanation:
From available data
Ψ1 = Ee = 10eV probability = 0.2
Ψ2 = Ee = 16eV, probability = 0.3
Ψ3 = Ee = 34eV, probability = 0.5
The magnitude of a
= a² = 0.2
= a = √0.2
|a| = 0.447
The magnitude of b
b² = 0.3
b = √0.3
|b| = 0.547
The magnitude of c
c² = 0.5
c = √0.5
|c| = 0.707
So in conclusion we have magnitude of a = 0.447
b = 0.547
c = 0.707
The magnitude of a , b and c are [tex]0.447, 0.547[/tex] and [tex]0.707[/tex] respectively.
Electron kinetic energy :The electron's wave function is given as,
[tex]\psi=a\psi _{1}+b \psi _{2}+c\psi _ {3}[/tex]
three values of the electron kinetic energy is given as,
[tex]\psi _{1}[/tex] has E = 10 eV, with probability 0.2
[tex]\psi _{2}[/tex] has E = 16 eV, with probability 0.3.
[tex]\psi _{3}[/tex] has E= 34 eV, with probability 0.5.
The value of a, b and c shown below,
[tex]a^{2}=0.2\\ \\a=\sqrt{0.2}=0.447\\ \\b=\sqrt{0.3}=0.547\\ \\c=\sqrt{0.5}=0.707[/tex]

The perimeter of a rectangle is 38 feet. The length is four more than twice the width.
Find dimensions plz
Answer:
length=14 width=5
Step-by-step explanation:
since the length is 4 more then subtract 4*2=8 which would equal 30 divide that by two since a rectangle has 4 sides two of which are the same,
than divide it by the getting 5 which is the width.
subtract 5*2=10 from 38 which would = 28
28divided by 2 is the length which is 14
Answer:
The answer are
Width=5ft
Length=14ft
Step-by-step explanation:
P=2(L+B)
P/2=2(L+B)/2
P/2=L+B
L=4+2W
38/2=4+2W+W
19=4+3W
3W=19-4
3W=15
divide both sides by 3
3W/3=15/3
W=5ft
L=4+2W
L=4+2(5)
L=4+10
L=14ft

The circumference of the circle will be C= 18.84 ft and the area of the circle will be [tex]A=28.27 ft^2[/tex]
What is area of the circle?The area of the circle is defined as the quantity of the space covered by the circle in a two-dimensional plane.
It is given in the question ;
Radius of the circle = 3 ft.
The area of the circle is given by the formula;
