Area of a triangle = 1/2 (base)(height)

Side AB is common to both triangles

BC = 5(BD)

Area ABD = 8, therefore Area ABC = 5(8) = 40

Answer:

Answer:

No

Step-by-step explanation:

5+10=15, which cannot be less than 17

The Assessment Triangle and the Domains and Dimensions of the Assessment Framework.

Perimeter of A/perimeter of B = a/b

Given that triangles ABC and DEF are similar triangles, we have the following:

Perimeter of triangle ABC = x

One side length of triangle ABC = 4 cm

Perimeter of triangle DEF = 12 + 6 + 9 = 27 cm

One side length of triangle DEF = 6 cm

Therefore:

x/27 = 4/6

Cross multiply

6x = (27)(4)

6x = 108

6x/6 = 108/6

x = 18

Thus, the perimeter of tr8angle DEF that is similar to triangle ABC is: 18 cm.

The roster form of the set P is; {-2, -1, 0, 1}

The builder notation of the set P is; {x : x ∈ I, −2 < x ≤ 1}

We are told that P is the set of integers that are greater than -3 and less than or equal to 1.

Roster form of sets is done by listing the elements of the set, separated by commas, inside a set of curly brackets.

Since P is the set of integers that are greater than -3 and less than or equal to 1, then the possible numbers are; (-2, -1, 0, 1)

The roster form is; {-2, -1, 0, 1}

By solving the linear matrices we got the values X = 1000000  , Y = 800000 ,  Z = 200000

According to algebra, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 4x + 5 = 15 consists of the two equations 4x + 5 and 15, which are separated by the 'equal' sign.

According to the given information

X + Y + Z  =  2000000

0.07X + 0.085Y + 0.095Z = 157000

Y = 4Z

Y = 4Z is substituted into the first and second equations as follows:

X + 5Z = 2000000

0.07X + 0.085 (4Z) + 0.095Z = 157000

X = 2000000 - 5Z

0.07X + 0.435Z = 157000

0.07 (2000000 - 5Z) + 0.435Z = 157000

140000 - 0.35Z + 0.435Z = 157000

0.085Z + 140000 = 157000

0.085Z = 17000

Z = 200000

Y = 800000

In linear equation, The number of miles that he walked when he was covered and 2/3 of the distance to the gym will be 7/30 miles.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                     Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Patrick walks 9/10 miles to the gym.

Then the number of miles that he walked when he was covered 2/3 of the distance to the gym will be

Answer:

5 tables

Step-by-step explanation:

Let x be the number of tables the school needs to rent, and c be the total cost of renting the tables.

We can use the following equation to represent the cost of renting from the first company:

c = 20 + 12x

And we can use the following equation to represent the cost of renting from the second company:

c = 30 + 10x

As c is the same constant in both equations, we can say the following:

20 + 12x = 30 + 10x

Now we can solve this equation by simplifying:

20 + 12x = 30 + 10x

20 + 2x = 30

2x = 10

x = 5

Therefore, the school will need to rent 5 tables for the cost to be the same from both renting companies.

Answer: 5 tables

Step-by-step explanation:

The first rental company will charge $32 for one table.

The second rental company will charge $40 for one table.

So if we make a table, and keep adding $12 to the first company and $10 to the second it will look like this.

First company                          Second company                   Table

 $32                                                  $40                                     1

 $44                                                  $50                                     2

 $56                                                  $60                                     3

 $68                                                  $70                                     4

 $80                                                  $80                                     5

Therefore, the school can rent 5 tables for the same price in both companies.

The inequality which represents is 2x + 3y ≤ 12 where x is the number of daisies and y is the number of tulips.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

Suppose the cost of one daisy is x while the cost of one tulip is y.

2x + 3y will be totally spent and it can be almost $12.

2x + 3y ≤ 12

Answer: Number of small boxes = 7, Number of large boxes =3

Step-by-step explanation:

Let x= Number of small boxes , y = Number of large boxes.

As per given , 30x+55y=375  (i)

x+y=10   (ii)

Multiply (ii) by 30, we get

30x+30y=300    (iii)

Eliminate (iii) from (i), we get

25y=75

⇒ y= 3   [Divide both sides by 25]

Put y=3 in (ii), we get

x+3=10 ⇒ x=7

Hence,  Number of small boxes = 7, Number of large boxes =3

The percent increase in the total number of students on the honor roll is   9.4% .

In the question,

it is given that ,

last year , the number of boys in the honor roll is = 60 boys ,

the number of girls in the honor roll is = 100 girls ,

total number of students last year = 160

percent increase in the number of boys in the honor roll is = 20% ,

so , number of boys become = 60 + (0.20*60) = 72 boys ,

percent increase in the number of girls in the honor roll is = 3% ,

so , number of girls become = 100 + (0.03*100) = 103 girls ,

total number of students this year = 103 + 72 = 175 .

increase in number of students = 175 - 160 = 15

So , percent increase is = (15/160) × 100

= 0.09375 × 100

= 9.375 %

≈ 9.4%

Therefore , the percent increase is 9.4% .

A variable is a quantity that could change depending on the circumstances of an experiment or mathematical problem. Typically, a variable is denoted by a single letter. The general symbols for variables most frequently used are the letters x, y, and z.

A constant component of a word as opposed to a variable. a measurement of some property or characteristic using a number (as of a substance, device, or process)

The function representing the graph is f(x) = (x + 5)²(x - 3)². The correct option is (a).

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

The given graph of the function cuts x axis at (-5,0) and (3,0) and y axis at (0,225) respectively.

Since the zeros of a function is the point at which it cuts the x-axis, the zeros at of the given functions are -5 and 3.

Which implies that the factors are (x + 5) and (x - 3) respectively.

The given factors are valid for options (a) and (d).

Now, at x = 0 f(x) should be 225.

It can be checked for both the options as follows,

(a) f(x) = (x + 5)²(x - 3)²

=> f(0) = (0 + 5)²(0 - 3)²

           = 5² × -3²
