Answer:
\(\frac{4}{5}\) or 0.8
Step-by-step explanation:
The question is asking what number multiplied by \(\frac{5}{6}\) equals \(\frac{2}{3}\). In equation form, this would be x ·
To find x, you would do \(\frac{2}{3}\) ÷ \(\frac{5}{6}\). When dividing fractions, you would use the keep-change-flip method. The first fraction stays the same, the sign flips from division to multiplication, and the numerator and denominator switch in the second fraction. Finally, multiply the fractions to find the answer.
Below is the explanation in step form.
1. \(\frac{2}{3}\) ÷ \(\frac{5}{6}\)
2. \(\frac{2}{3}\) · \(\frac{6}{5}\)
3. \(\frac{2}{1}\) · \(\frac{2}{5}\) (You can cancel out the 3 and the 6.)
3. \(\frac{12}{15}\) (You can also multiply and simplify.)

Is the statement “ for a set of whole numbers, the longest numeral will belong to the largest number” true or false? Why?
Numerals are symbols and figures that are used to denote or represent numbers.
It is false that “for a set of whole numbers, the longest numeral will belong to the largest number”
How to determine the true statementThe length of a numeral does not determine the value of the number,
The above statement means that
The whole number with the longest numeral in a set may or may not be the largest.
Take for instance the numbers 8 and 9.
In Roman numerals,
8 is represented with VIII and 9 is represented with IX
The numeral VIII is longer than the numeral IX, but IX is greater than VIII
Hence, the statement is false

What are the properties of similar triangles?In Mathematics and Geometry, two triangles are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.
Additionally, the lengths of three (3) pairs of corresponding sides or corresponding side lengths are proportional to the lengths of corresponding altitudes when two (2) triangles are similar.
Based on the side, side, side (SSS) similarity theorem, we can logically deduce the following congruent and similar triangles:
ΔCJG ≅ ΔCEA (line segment GJ is parallel to line segment AE)

how to do surface area
Answer:
Step-by-step explanation:
Multiply the length and width, or c and b to find their area. Multiply this measurement by two to account for both sides. Add the three separate measurements together. Because surface area is the total area of all of the faces of an object, the final step is to add all of the individually calculated areas together.
Answer:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Alijah's taxable income puts him in the first tax bracket, over $8,350 but not surpassing $33,950. Hence, his tax due is a base of $835 plus 15% of the income that exceeds $8,350. This results in a total tax payable of $850. Option B is the correct answer.
Alijah's taxable income falls within the first bracket of the tax table given, being over $8,350 but not over $33,950.
This bracket requires him to pay a tax of $835.00 plus 15% of the amount over $8,350.
He has a surplus of $100 over the $8,350 threshold (i.e., $8,450 - $8,350), and 15% of $100 equals $15.
Therefore, the total tax he owes would be the fixed amount of $835.00 plus the $15.00 calculated, which sums up to $850.00.
Thus, looking at the provided options, option B ($850.00) would be the correct answer.

On the past two quizzes, a student scored a 75 and 83. Write and solve a compound inequality to find the possible values for the 3rd quiz score that would give her an average between 85 and 90, inclusive.
The possible values for a third quiz score that would give her an average between 85 and 90, inclusive is: 97 ≤ x ≤ 112.
How to determine the average?In Mathematics, the average of these quiz scores can be calculated by using the following formula:
Average = Sum of quiz score/Number of quiz scores
Note: Let the variable q represent the student's score on the third (3rd) quiz.
Substituting the given parameters into the formula, we have the following;
Average = (75 + 83 + q)/3
Average = (158 + q)/3
This ultimately implies that, an average between 85 and 90, inclusive is given by this compound inequality:
85 ≤ (158 + q)/3 ≤ 90
Multiplying all through by 3, we have the following:
255 ≤ (158 + q) ≤ 270
Subtracting 158 from both sides of the inequality, we have the following:
97 ≤ x ≤ 112

The exact value of x is 2.1859 when the equation is 11ˣ=189 and the approximate to the nearest hundredth is 2.19.
Given that,
We have an equation 11ˣ=189
We have to find the exact value of x and the approximately nearest hundredth value.
Take the equation,
11ˣ=189
The x is in the power to get the x variable we have to take the logarithm here.
By taking logarithm we have a formula
log(aˣ)=xloga
So,
Taking logarithm on both sides
log(11ˣ)=log(189)
xlog11=log189
x=log189/log11
x=2.276/1/041

Compare the volume and surface area of a sphere with radius 4 in. with that of a cube with sides measuring 6.45 in
Compare the volume and surface area, it can be said that the volume of the sphere is approximately equal to the volume of the cube, but the cube has a greater surface area.
What is volume?It is the space occupied by a body, it is calculated by multiplying its dimensions, for example: length, height and width.
Information about the problem:
r(sphere) = 4 inl(cube) = 6.45 inUsing the formula of the volume and the surface area of the sphere we get:
v(sphere)= 4/3 (π * r³)
v(sphere)= 4/3 *π*(4)^3 in^3
v(sphere)= 268.08 in^3
Rounding down = 268 in^3
surface area(sphere) = 4*π*r²
surface area(sphere) = 4*π*(4)^2
surface area(sphere) = 201.062 in^2
v(cube)= l³
v(cube)=(6.45)^3
v(cube)= 268.34 in^3
Rounding down = 268 in^3
surface area(cube) = 6*l²
surface area(cube) = 6 * (6.45)^2
surface area(cube) = 249.62 in^2
Therefore:
The volume of the sphere is approximately equal to the volume of the cube, but the cube has a greater surface area.

Step-by-step explanation:
On the interval (3π/2, 2π), both the sine and cosine functions are increasing.
What are the values of sine and cosine functions at (0, π/2, π, 3π/2, 2π)?The values of sine and cosine functions at (0, π/2, π, 3π/2, 2π) are as follows:
sin (0) = 0; cos (0) = 1
sin (π/2) = 1; cos (π/2) = 0;
sin (π) = 0; cos (π) = - 1
sin (3π/2) = - 1; cos (3π/2) = 0
