A man orders5 times as many boxes of ballpoint pens as boxes of felt tip pens. Ballpoint pens cost $4.31 per box, and felt tip pens cost$3.44. If the mans order of pens totaled $99.96 how many boxes of each pen did he buy?

Answers

Answer:

76.38

Step-by-step explanation:

x = the number of boxes of felt tip pens

5x = the number of boxes of ballpoint pens

5x*4.41 + x*3.41 = 76.38

Factor 10x2 – 42x – 108.
Question 20 options:

A)

(5x + 9)(x + 6)

B)

Answer:

B

Step-by-step explanation:

You have to know how to factor polynomials.

2(5x^2-21x-54)

2(5x^2-30x+9x-54)

2(5x(x-6)+9(x-6))

100 POINTS AND BRAINLIEST !!!!! (I need the answer ASAP) A school is planning to construct two rectangular play areas in the playground.

The length of play area A must be 1 foot longer than four times its width. The width of play area B must be 2 feet longer than the width of play area A, and the length must be 2 feet longer than three times its own width. In addition, the areas of the two play areas must be equal.

Write a system of equations to represent this situation, where y is the area of the play areas and x is the width of play area A. Which statement describes the number and viability of the system’s solutions?

A.
The system has two solutions, and both are viable because they result in positive widths.
B.
The system has only one solution, but it is not viable because it results in a negative width.
C.
The system has two solutions, but only one is viable because the other results in a negative width.
D.
The system has only one solution, and it is viable because it results in a positive width.

What is the solution to the system of linear equations?
O (-3,0)
O (-3, 3)
O (0, 2)
O (3, 1)

Answers

(0,2)

The solution would just be where these two functions cross, which is at the point (0,2) in this case.

The point of intersection of lines represents the common solution of the system of linear equations. The solution of linear equations given in the graph is (0,2).

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Linear equation represents a line on the graph.

The system of linear equations represents couple/s of linear equations or lines.

Here, The solution of system of linear equations means the common point satisfying the different linear equations.

Hence, Graphically, the point of intersection of two lines represents the common solution of these two lines or simply the solution of the system of linear equations.

So, the point of intersection from the given graph is (0,2).

Therefore, the solution of linear equations given in the graph is (0,2).

We would use the Pythagorean thrm

a=11 b=height of building c=30

What is the sector area of a sector created
by circle with a radius of 2 m and a 140°
central angle.

Answers

Answer:

Area of sector = 4.88 m ²

Step-by-step explanation:

Given:

Angle = 140°

Radius = 2 m

Find:

Area of sector

Computation:

Area of sector = [θ/360][πr²]

Area of sector = [140/360][(22/7)(2)²]

Area of sector = 4.88 m ²

When would there be only four different equations for a set of math mountain numbers?

Answers

Answer:

Only when any equation you find among those numbers can be simplified into one of the four main equations, which means you only have four different true statements and lots of equivalences. 20 = 40 - 20. As the two addends are the same, so there would be only four different equations for a set of math mountain numbe

6 foot tall man has a 9 foot shadow at the same time a tree standing next to him as a 30 foot shadow how tall is the tree?

Answers

27 feet? Or 20?
I did 9-7= 3 so 30-3=27
If not 9/7=1.5 so 30/1.5=20

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

From the right angle triangle,

The ratio of the man height and his shadow is equal to the tree height(h) and its shadow.

6/9 = h/30

h = 20 feet

Thus, the tree is 20 feet tall if the 6-foot tall man has a 9-foot shadow at the same time a tree standing next to him as a 30-foot shadow.

(Volume for a rectangular shape is length x width x height)

We can split up this 3D composite figure into two main parts (as shown in the picture I attached), and find each part’s volume before adding them together for the total volume.

Cube —> 5x5x5 —> 25x5 = 125 in^3

Rectangular Prism —> 20x5x5 —> 100x5 = 500 in^3

125 + 500 = 625

Miguel and Kat are reading the same book. Miguel reads 5 times as many
pages of the book as Kat. Together they read 54 pages. Write an equation
that can be used to find how many pages Kat read.

Answers

Answer:

[tex]k=\dfrac{m}{5}[/tex]

Step-by-step explanation:

Let Kat reads k pages of the book.

Miguel reads 5 times as many  pages of the book as Kat. So,

m = 5k ...(1)

Together they read 54 pages. i.e.

m+k = 54 ...(2)

From equation (1),

[tex]k=\dfrac{m}5{}[/tex]

Hence, the equation that can be used to find how many pages Kat read is equal to [tex]\dfrac{m}{5}[/tex].
