a salesperson has averaged $120 in commissions for each of the past ten days. For how many days must her commissions average $160 in order to bring her overall average to %150?

Answers

OKOK

A salesperson averaged $120 per 10 days sooo 120/10 is 12 so about 12 per day

So,
You guess the amount that could make up a number around 150or 160

So 12 x3 = 36 + 120=156 hallelujah!

So, 3 more days until she can average $160 in order to bring her overall average to 150%.....

Each edge of a cube measures 4.7 in. What is the surface area of the cube? Enter your answer, as a decimal, in the box.

Answers

There are 6 faces and area of each face = 4.7^2

so surface area of the whole cube = 6 * 4.7^2 = 132.54 in^2

The measure of an edge of a cube = 4.7 in

We have to determine the surface area of the cube.

The surface area of a cube is the area of the six squares that cover it. The area of one square is [tex] a^{2} [/tex]. Therefore, area of six squares = [tex] 6a^{2} [/tex].

Surface area of cube = [tex] 6a^{2} [/tex] , where a is the edge of a cube

Therefore, Surface area of this cube

= [tex] 6a^{2} [/tex]

= [tex] 6 \times (4.7)^{2} [/tex]

= 132.54 square inches.

Therefore, surface area of the cube is 132.54 square inches.

Two angles are supplementary. If one measures x and the other angle measures x+ 30, what is the value of x ?

Answers

This year Cornell’s class took one more than three times as many field trips as last years class. This year Cornell’s class took a total of 7 trips. How many trips did his class take last year

Answers

To find the number of field trips Cornell's class took last year, we set up the equation 3x + 1 = 7, where x represents the number of trips last year. Solving this, we find that Cornell's class took 2 field trips last year.

The question involves a basic mathematical equation to determine the number of field trips taken by Cornell's class last year. Since this year Cornell's class took 7 trips, and this number is one more than three times the amount of the previous year, we can set up the equation as x being the number of trips taken last year:

3x + 1 = 7

To find x, subtract 1 from both sides of the equation:

3x = 7 - 1

3x = 6

Now divide both sides by 3 to solve for x:

x = 6 / 3

x = 2

So, Cornell's class took 2 field trips last year.

how do I do identify calculate the area and perimeter for quadrilaterals

Answers

length times width for area and add all the sides up for perimeter

To calculate the area and perimeter of a quadrilateral, you need to know the shape of the quadrilateral and the lengths of its sides. The area can be calculated using different formulas depending on the shape, such as trapezoid, rectangle, parallelogram, or square. The perimeter is calculated by adding the lengths of all the sides.

To calculate the area and perimeter of a quadrilateral, we need to know the shape of the quadrilateral and the lengths of its sides.

1. Area:

Trapezoid: The area of a trapezoid can be calculated using the formula A = (base1 + base2) × height / 2, where base1 and base2 are the lengths of the parallel sides, and height is the distance between the parallel sides.Rectangle: The area of a rectangle is calculated by multiplying its length by its width, so A = length × width.Parallelogram: The area of a parallelogram is calculated using the formula A = base × height, where base is the length of one side and height is the perpendicular distance between the base and the opposite side.Square: The area of a square is calculated by multiplying the length of any side by itself, so A = side × side.

2. Perimeter:

Trapezoid: The perimeter of a trapezoid is calculated by adding the lengths of all its sides.Rectangle: The perimeter of a rectangle is calculated by adding the lengths of its four sides, so P = 2 × length + 2 × width.Parallelogram: The perimeter of a parallelogram is calculated by adding the lengths of its four sides.Square: The perimeter of a square is calculated by multiplying the length of one side by 4, so P = 4 × side.

Why is it more difficult to use repeated addition when multiplying two mixed numbers than it is to use repeated addition when you are multiplying a mixed number by a whole number?

Answers

The reason it is more difficult to use repeated addition when multiplying two mixed numbers when compared to multiplying a mixed number and a whole number is because when you are multiplying a mixed number by a whole number, you have a whole number of groups of the mixed number. Ex: 1 1/2 x 3 would be 3 groups of 1 1/2, so
1 1/2 + 1 1/2 + 1 1/2.

If this were 1 1/2 x 2 1/2, you have 2 whole groups of 1 1/2, but then you would need to represent 1/2 group which requires multiplying or dividing first.

The reason why it is more difficult to use repeated addition when multiplying two mixed numbers than it is to use repeated addition when you are multiplying a mixed number by a whole number is:

There is a whole number of groups of the mixed number. Ex: 1 1/2 x 3 would be 3 groups of 1 1/2, so 1 1/2 + 1 1/2 + 1 1/2.

This refers to the mathematical operation that involves to find the product of a set of numbers.

What is Mixed Number?

With this in mind, if we have mixed numbers like 1 1/2 x 2 1/2, and we were to use repeated addition to multiply them, we would have 2 whole groups of 1 1/2, but then we would need to represent 1/2 group which requires multiplying or dividing first.

So I'm supposed to find the average of the two middle numbers, which are 8.9 & 9.0. What does it mean when it says I'm supposed to "find the AVERAGE of the two middle values"?

Answers

it means that you add them two together and divide by 2

The average is 8.9+9=17.9
17.9/2=8.95.
So, that means the median or middle number is 8.95.

Also, you have to add the 2 middle numbers and divide it by 2 to find the median if there is an even amount of numbers.

A group of children each rode a horse to the bottom of the canyon. They had 20 eyes and 30 legs between them, how many horses were there

Answers

there were 10 horses

Final answer:

You can calculate that, since all children and horses have two eyes, and that children have two legs and horses have four, and the total number of eyes is 20 and the total number of legs is 30, there were 5 children and 5 horses.

Explanation:

This problem can be solved using basic algebra. We need to count the numberOfChildren and numberOfHorses in a manner where each child and each horse contribute two eyes and with each child having two legs while each horse has four legs.

Let's make two assumptions:

numberOfChildren = number of children numberOfHorses = number of horses

So, we can write two equations according to the question:

The total number of eyes = 20 (which implies that numberOfChildren + numberOfHorses = 10, because each creature, whether child or horse, has two eyes)The total number of legs = 30 (which implies that 2*numberOfChildren + 4*numberOfHorses = 30, as each child has two legs and each horse has four)

By solving these two equations, we find that the numberOfChildren = 5 and numberOfHorses = 5.

Answers

To find the value of 'a' when a = 37 degrees and b = 6, trigonometry principles are used to calculate 'a' as approximately 34.08 degrees.

Given: a = 37 degrees and b = 6. To find a.

Using trigonometry: We can use the trigonometric ratio tangent to find a. tan(a) = b/c, where c is the hypotenuse. So, tan(37) = 6/c. Therefore, c = 6/tan(37) = 8.37. Hence, a = tan-1(b/c) = tan-1(6/8.37) ≈ 34.08 degrees.

Answer: Therefore, a = 34.08 degrees.

if a triangle has side lengths of 22,32,and 55 units what type of triangle is it
acute,obtuse,right,no solution

Answers

Answer: No solution

A 'triangle' with side lengths of 22, 32, and 55 is no solution because it cannot form a triangle. In order for it to be a triangle, the sum of the two shorter side lengths must be greater than the longest side length.

22 + 32 < 55
54 < 55

Final answer:

A triangle with side lengths of 22, 32, and 55 units is an obtuse triangle.

Explanation:

A triangle with side lengths of 22, 32, and 55 units is an obtuse triangle.

To determine the type of triangle, we can use the Pythagorean theorem. If the sum of the squares of the lengths of the two shorter sides is greater than the square of the length of the longest side, then the triangle is obtuse. In this case, 22^2 + 32^2 = 484 + 1024 = 1508, which is greater than 55^2 = 3025, so the triangle is obtuse.

An obtuse triangle is a triangle with one angle greater than 90 degrees. In this case, the angle opposite the longest side will be greater than 90 degrees.

Chris is twice as old as Don, and next year the sum of their ages will be four times as much as Don’s age last year. Find their present ages.

Answers

Answer:

Chris is 12 years old and Don is 6 years old.

Step-by-step explanation:

;)

The present age of Don is 6 years old and Chris age is 12 years.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let's denote Don's current age as x.

As Chris is twice as old as Don, Then, Chris's current age is 2x.

Next year, their ages will be x+1 and 2x+1 respectively.

The sum of their ages will be four times as much as Don’s age last year.

(x+1) + (2x + 1) = 4(x-1).

Expanding and solving for x:

3x + 2 = 4x - 4

x = 6

So, Don is 6 years old and Chris is 2×6 = 12 years old.

Hence, the present age of Don is 6 years old and Chris age is 12 years.
