Find the volume of a cube if its area of four walls is 16 cm square.

A student needs to receive 20 out of a possible 50 points on the test in order to receive a passing grade of 40%.

The term "proportionate" refers to relationships that always have the same ratio. For instance, the average number of apples per tree influences how many trees there are in an orchard and how many fruits there are in a harvest of apples. A linear relationship between two numbers or variables is referred to in mathematics as being proportionate. In the same way as the first quantity doubles, so does the other. The other decreases as well when one of the variables is reduced to 1/100th of its previous value. When two quantities are proportional, it means that when one rises, the other rises as well and that the ratio between the two quantities is constant at all values. As an example, consider a circle's diameter and circumference.

No, you cannot form a triangle with side lengths 8, 9, and 17. The sum of any two sides of a triangle must be larger than the remaining side. 8 + 9 = 17, which is not larger than 17.

1. A triangle is a three sided polygon with three angles and three sides.

2. In order to form a triangle, the sum of any two sides of the triangle must be larger than the remaining side.

3. To test if a triangle can be formed with side lengths 8, 9, and 17, we need to add two of the sides together and see if the result is larger than the remaining side.

4. 8 + 9 = 17, which is not larger than 17, so a triangle cannot be formed with side lengths 8, 9, and 17.

5. Therefore, you cannot form a triangle with side lengths 8, 9, and 17.

The degree of polynomial in 5x³ 4x² 7x is 3, since the highest power of variable is 3.

The degree of polynomials, which determines the maximum number of solutions a function could have and how frequently a function will cross the x-axis on a graph, is one of the key ideas in mathematics. Polynomials are also important because they help us understand how functions can be represented mathematically. In the equation involving polynomials, it has the highest exponential power.

In a polynomial equation, a variable's greatest power is its degree. Only the terms with variables are taken into consideration when calculating a polynomial function's degree. The polynomials degree can be determined by looking at the variable term's highest exponential power.

Answer:

10

Step-by-step explanation:

35% of x = 3.5  To change a percent to a decimal, divide by 100%

.35x = 3.5  Divide both sides by 3.5

[tex]\frac{.35x}{.35}[/tex] = [tex]\frac{3.5}{.35}[/tex]

x = 10

Check:

.35 x 10 = 3.3.5 = 3.5

Answer:

10

Step-by-step explanation:

Let the unknown number be x.

35% of x = 3.50

35/100 * x = 3.50

35x = 3.50 * 100

35x = 350

x = 350/35

x = 10

Hence, the unknown number is 10.

Saad's income tax will be N.I.L.

Here, saad's yearly income is Rs 2,36,000.

The rate of income tax on his income will be nil because,

    INCOME                                TAX RATE

0-2,50,000                                    NIL

2,50,000-5,00,000                       5%

5,00,001-10,00,000                       20%

More than 10,00,000                      30%

                          Computation of tax liability of Saad

Tax on 1st 2,36,000 = N.I.L

As his income is less than 2,50,000 no income tax shall be charged to saad's income.

Therefore, the tax liability of saad would be 0.

2 × 10 - 3 = 17

8 × 10 = 80

80 - 17

= 63

An expression that describes the given situation is; Total yards = -6 - 5 and the solution is -11

In mathematics, a positive number means we have a plus sign before the number which means if we have +2, it means that there has been a gain of 2 units. In a similar manner, a negative number represents a loss which means that if we have -3, it simply means there is a loss or reduction of 3.

Now, we are told that during a football game, the hawks lost 5 yards due to a penalty and lost 6 yards from a quarterback sack. Thus, using the concept of positive and negative numbers above, we can develop the total number of yards as;

Total yards = -6 - 5

Total yards = - 11 yards

This represents a loss.

Answer:

77.472222 etc

Step-by-step explanation:

By solving the equation 5t - 3 = 3t - 5 we get the equation is true when t = -1. So the solution is t = -1.

To solve the equation 5t - 3 = 3t - 5, you can use algebraic manipulation to isolate the variable on one side of the equation.

The first step is to get all the terms with the variable on one side of the equation and all the constant terms on the other side.

5t - 3 = 3t - 5

adding 3 to both sides:

5t = 3t - 2

subtracting 3t from both sides:

2t = -2

then divide both sides by 2:

t = -1

So the solution is t = -1, meaning that when t = -1, the equation is true.

The measure of ∠Z is 165 degrees to the nearest degree.

In a triangle, the measure of each angle is equal to the sum of the measures of the other two angles subtracted from 180 degrees. This is known as the Triangle Sum Theorem.

Given that x = 5.2 inches, y = 9.8 inches, and z = 7.1 inches in triangle XYZ, we can use the theorem to find the measure of angle Z.

∠Z = 180 - (x+y)

∠Z = 180 - (5.2+9.8)

∠Z = 180 - 15

∠Z = 165

So the measure of ∠Z is 165 degrees to the nearest degree.

Therefore, The measure of ∠Z is 165 degrees to the nearest degree.

If star A is closer to us than star B, then Star A's parallax angle is: Larger than that of Star B.

Hence, option (A) is correct choice.

The parallax of a star at a distance of 10 parsecs would be 0.1′′ since parallax is inversely proportional to distance. The parallax of Proxima Centauri, a star in the triple system of Alpha Centauri, is 0.76813′′, indicating that it is 4.24 light-years away from Earth at a distance of 1/0.76813, or 1.302 parsecs.

The apparent shift in an object's location caused by a change in the observer position is known as parallax. This apparent shift is measured (in arc seconds) is reversed to provide the distance from the background stars (in parsecs).

The definition of an object's absolute magnitude is the apparent magnitude the object would have if it were observed at a distance of precisely 10 parsecs (32.6 light-years), without light extinction.
