Victoria that she always incorporates The Five Principles into her conversations with other businesses, government officials, and other partners and leaders. The writing core is tougher and leaves a lighter trace on the paper as the number increases.
Let number of pens =x
And number of pencils =y
⇒ x+y=40
⇒(5+y)+(x−5)=4x
⇒3x=y
Substituting in above equations ;
⇒x+3x=40

What is the value of log2 log32?
the value of log2 log32 is 0.5899 and the base of the logarithm is raised to the value that was equated earlier and this expression is equal to the logarithm.
logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.J
The logarithmic equation that has the same solution as x-4=2^3 is log2(x-4)=3.
Logarithm
The logarithm of a number can be calculated from the following relationship:
Thus, the base of the logarithm is raised to the value that was equated earlier and this expression is equal to the logarithm.
So, we have that the third expression
Therefore, this expression is the one corresponding to x-4=2^3.

Kyle and Steve start at the same point and walk in opposite directions. If Kyle walks at 2 mph and Steve walks at 2 mph, how far apart will they be after 3 hours?
Answer:
12 miles
Step-by-step explanation:
Kyle's speed = 2 mph
Steve's speed = 2 mph
Time traveled = 3 hours
Distance apart after 3 hours
Distance moved by Kyle + Distance moved by Steve
Distance = Speed * time
Distance moved by Kyle = 2 * 3 = 6 miles
Distance moved by Steve = 2 * 3 = 6 miles
Total distance apart = 6 + 6 = 12 miles

Tom got a Mr. Potato Head for his birthday. It came with $3$ hairstyles, $2$ sets of eyebrows, $1$ pair of googly eyes, $2$ sets of ears, and $2$ sets of lips, a pair of regular shoes, and a bonus pair of clown shoes. If a complete Mr. Potato Head personality includes eyebrows, eyes, ears, lips, shoes and optionally hair, how many different wacky personalities can Tom come up with? Note that Mr. Potato Head can be bald. Note: You cannot "mix and match". For example, you cannot take the left eyebrow from one pair and the right eyebrow from the other pair.
Answer: Tom can come up with 13 different wacky personalities for Mr Potato Head.
Step-by-step explanation:
Tom can come up with 3 different hairstyles for Mr Potato Head, 2 sets of eyebrows, 1 pair of googly eyes, 2 sets of ears, and 2 sets of lips. He also has 2 pairs of shoes to choose from. If Mr Potato Head can be bald, Tom can also choose to not include a hairstyle.
In total, Tom can come up with 3+2+1+2+2+2+1=13 different combinations of features for Mr Potato Head. Since each combination represents a different personality, Tom can come up with 13 different wacky personalities for Mr Potato Head.

What is an inverse function?First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.
We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.
Given, k(x) = 4 ÷ 5x - 6.
k(x) = (4/5x) - 6.
Let, y = k(x).
y = (4/5x) - 6.
(4/5x) = y + 6.
1/x = 5(y + 6)/4.
x = 4/{5(y + 6)}.
y = 4/{5(x + 6)}.
k⁻¹(x) = 4/{5(x + 6)}.
k⁻¹(8) = 4/{5(8 + 6)}.
k⁻¹(8) = 4/{5(14)}.
k⁻¹(8) = 4/70.
k⁻¹(8) = 2/35.

Hi there!
We can find the values of x using right triangle trig.
Recall: SOHCAHTOA
sin = O/H (Opposite / Hypotenuse)
cos = A/H (Adjacent / Hypotenuse)
tan = O/A (Opposite / Adjacent)
Thus:
6. A = 14, H = 15
cos x = 14/15
cos⁻¹ (14/15) = x
x = 21.04° ≈ 21°
7. O = 19, A = 23
tan x = 19/23
tan⁻¹(19/23) = x
x = 39.56° ≈ 40°
8. A = 9, H = 17
cos x = 9/17
cos⁻¹(9/17) = x
x = 58.03 ≈ 58°
9. O = 43, H = 45
sin x = 43/45
sin⁻¹(43/45) = x
x = 72.85° ≈ 73°

Factor out the greatest common factor. If the greatest common factor is 1, just retype the

20q ^10 - 10q⁹+ 30q^8 + 20q^7
The greatest common factor of 20q¹⁰ - 10q⁹ + 30q⁸ + 20q⁷ is 10q⁷.
What is the greatest common factor?The GCF stands for greatest common factor. In this case, greatest can be changed to highest, and factor to divisor. The highest common factor is often referred to as the biggest common factor, highest common factor, or highest common divisor (GCD).
The largest number among all the common factors of the given numbers is known as the GCF (Greatest Common Factor) of two or more numbers. The greatest integer that may be used to divide two natural numbers x and y without producing any remainders is called their GCF. There are three main methods for calculating GCF: division, multiplication, and prime factorization.
the factor of 20q¹⁰ is 2*2*5*q*q*q*q*q*q*q*q*q*q
the factor of 10q⁹ is 2*5*q*q*q*q*q*q*q*q*q
the factor of 30q⁸ is 2*3*5*q*q*q*q*q*q*q*q
the factor of 20q⁷ is 2*2*5*q*q*q*q*q*q*q
So that the common factor of all the above terms is 2*5*q*q*q*q*q*q*q
the common factor of all the above terms= 10q⁷
So that the greatest common factor of 20q¹⁰ - 10q⁹ + 30q⁸ + 20q⁷ is 10q⁷.

Answer:
F.
Step-by-step explanation:
y = k/x where k is a constant
given that x = 4 when y = 3, we have:
3 = k/4
So, k =12.
The equation of variation is:
y = 12/x
When x = 15
y = 12/15 = 4/5.

Which statements are necessary to prove the two triangles are congruent by SSS? (ASAP HELP PLS!!!)
Answer:
C
Step-by-step explanation:
To prove that two triangles are congruent using the SSS Congruence criterion, we must establish that all three sides of one triangle are equal to all the corresponding sides of the other.
Thus,
Side AD in ∆ADB is congruent to side AD in ∆ADC.
Side BD in ∆ADB is congruent to side CD in ∆ADC.
Side AB in ∆ADB is congruent to side AC in ∆ADC.
Therefore, based on the SSS congruence criterion, it is concluded that both triangles are congruent.

On applying the midpoint theorem the values of x, y, and z are 2, 10 and 8 respectively.
What is the mid-point theorem?
According to the midpoint theorem, the line segment connecting any two triangle sides' midpoints is parallel to and equal to half of the third side.
The outer triangle is ABC and the inner triangle is DEF.
It can be seen that sides AB, BC and AC are equally divided such that AD=DB,
BE=EC and
CF=FA.
So, this proves that point D, E and F are the middle points of AB, BC and AC respectively.
Now, according to the midpoint theorem -
DF = 1/2(BC)
Plugging in the values -
x = (5x-6)/2
2x = 5x-6
2x-5x = -6
-3x = -6
x = 2
Now, for side DE -
DE = 1/2(AC)
Plugging in the values -
12 = (2z+8)/2
24 = 2z+8
24-8 = 2z
16 = 2z
z = 8
Now, for side EF -
EF = 1/2(AB)
Plugging in the values -
y = 20/2
y = 10
Therefore, the values obtained are x=2, y=10 and z=8.

Por lo tanto, se le da 4 chocolates a cada niño y el 1 chocolate restante se divide en 5 partes iguales y se le da 1/5 a cada niño. Por lo tanto, cada niño recibe 4 1/5 chocolates.
Distribuir 10 bombones entre 3 niños;
10/3 = 3 resto 1

How do you solve a 3 by 3 system of equations using matrices?
The solutions can be read off of the diagonal entries in the reduced matrix.
To solve a 3 x 3 system of equations using matrices, first we need to create the augmented matrix for the system of equations. The augmented matrix contains the coefficients of the variables and the constants for each equation on each row. Then we can use row operations to reduce the augmented matrix to reduced row-echelon form. This can be done by adding or subtracting rows to each other, multiplying or dividing a row by a non-zero number, and swapping two rows. After reducing the matrix to row-echelon form, we can back-substitute the solutions to the system of equations. The solutions can be read off of the diagonal entries in the reduced matrix. For example, if the matrix is reduced to the form [a b c d e f g h i] then the solution to the system of equations is x = d/a, y = e/b, and z = f/c.

b. 0.95
Step-by-step explanation:
a. 5 percent increase
5% = 0.05
Because it is increasing, so we add 1
1 + 0.05 = 1.05
b. 12 percent decrease
12% = 0.12
Because it is decreasing, so subtract 1
1 - 0.05 = 0.95

Find two consecutive odd integers such that the sum between twice the smallest and the biggest is 35.
Answer:
Consecutive odd numbers will be 11 and 13.
Step-by-step explanation:
Let the two consecutive odd integers are n and (n + 2).
From the given question,
Sum between twice the smallest and the biggest is 35.
Since, smallest number is 'n' and biggest is (n + 2)
Therefore equation will be,
2n + (n + 2) = 35
(2n + n) + 2 = 35
3n + 2 = 35
3n = 33
n = 11
And (n + 2) = 13
Consecutive odd numbers will be,
11, 13
