▹ Answer

2) b = 9

3) c = 5

4) d = 5

5) e = 12

6) f = 10

7) g = 16

8) h =6

9) i = 4

10) j = 4

11) k =5

12) l = 7

13) m = 3

14) n = 7

15) o = 4

16) p = 15

17) q = 15

18) r = 12

19) s = 15

▹ Step-by-Step Explanation

2) b - 1 = 8 → 1 + 1 = crossed out 8 + 1 = 9 → b = 9

3) c + c = 10 → c has to be the same so, 5 + 5 = 10 → c = 5

4) d + 6 = 11 → 6 - 6 = crossed out 11 - 6 = 5 → d = 5

5) e - 5 = 7 → 5 + 5 = crossed out 7 + 5 = 12 → e = 12

6) f + f + f = 30 → f has to be the same so, 10 + 10 + 10 = 30 → f = 10

7)  1/2 g = 8 → 8 ÷ 1/2 = 16 → g = 16

8) 2h = 12 → 2 ÷ 2 = h 12 ÷ 2 = 6 → h = 6

9) i + 9 = 13 → 9 - 9 = crossed out 13 - 9 = 4 → i = 4

10) 14 - j = 10 → 14 - 10 = 4 10 - 10 = crossed out → j = 4

11) 3k = 15 → 3 ÷ 3 = k 15 ÷ 3 = 5 → k = 5

12) 11 - l = 4 → 11 - 4 = 7 4 - 4 = crossed out → l = 7

13) 2m - 1 = 5 → 5 - 1 = 4 → 2m = 4 → 4 ÷ 2 = 2 → m = 2

14) 2n + 1 = 15 → 15 - 1 = 14 → 2n = 14 → 14 ÷ 2 = 7 → n = 7

15) 6o = 24 → 24 ÷ 6 = 4 → o = 4

16) p ÷ 3 = 5 → 5 * 3 = 15 → p = 15

17) q ÷ 5 = 3 → 3 * 5 = 15 → q = 15

18) r + 4 = 16 → 4 - 4 = crossed out 16 - 4 = 12 → r = 12

19) 20 - s = 5 → 20 - 5 = 15 → s = 15

Hope this helps!

Step-by-step explanation:

2) b-1=8

b =8+1= 9

3) c+c=10

2c=10

divide both sides by 2

c=5

4) d-6= 11

d=11+6=17

5) e-5=7

e= 7+5=12

6) f+f+f=30

3f=30

f=10

7) 1/2g=8

divide both sides by 1/2

g=16

8) 2h= 12

divide both sides by 2

h=6

9) i+9=13

i= 13-9

i=4

10) 14-j=10

-j=10-14

-j= -4

divide both sides by-1

j=4

11) 3k=15

divide both sides by 3

k=5

12) 11-I=4

-I=4-11

-I= -7

divide both sides-1

I=7

13) 2m-1=5

2m=5-1

2m=4

divide both sides by 2

m=2

14) 2n+1=15

2n=14

divide both sides by 2

n=7

15) 6o=24

divide both sides by 6

o=8

16)p/3=5

multiply both sides by the multiplcative inverse of 1/3 which is 3

p=15

17) q/5=3

multiply both sides by 5 (multiplcative inverse)

q=15

18)r+4=16

r=16-4

r=12

19) 20-s=5

-s=5-20

-s= -15

divide both sides by-1

s=15

Step-by-step explanation:

Answer:

[tex]\boxed{OptionA}[/tex]

Step-by-step explanation:

More than always indicates "ADDITION". So the mathematical operation is "+".

Answer:

A. +

Step-by-step explanation:

The key word in the phrase is "more than"

That signifies an increase of value which is addition's main function

If the number that was represented in the phrase is x, then we could write out an equation

x=q+15

Step-by-step explanation:

f(x) =  y

so f(4.999) = -5 when x = 4.999

f(5)= undefined because open circles means > or < with out the line underneath that means equal to

f(5.0001)= 7 when x=5.0001

f(9)= 7 when x=9 because the closed circle means ≥ or ≤ or equal to

Answer:

840 female students

Step-by-step explanation:

The total percentage of students is 100%, so, the percentage of female  students = 100% - 47.5%

=52.5%

Multiply the total no. of students by the percentage to get the no. of female students.

1600 x 52.5%

= 840 female students

You can also obtain the same answer by first multiplying the male percentage to find the no. of male students, then subtracting it from the total 1600.

Answer:

(a) Nominal

(b) Nominal

(c) Interval

(d) Nominal

(e) Interval

Step-by-step explanation:

There are four distinct level of measurements: nominal, ordinal, interval and ratio.

(a)

Majors of randomly selected students at a university.

Level of measurements: nominal

Because in case of nominal level of measurements the variables are classified  using names, labels, alpha numeric data, and so on.

(b)

Name of the cities in Oregon.

Level of measurements: nominal

Because in case of nominal level of measurements the variables are classified  using names, labels, alpha numeric data, and so on.

(c)

The years in which economists have deemed the U.S. to be in recession.

Level of measurements: interval

Because in case of interval level of measurement, the data is not only classified and ordered, but it also specifies that the distances between each interval on the scale that are equal throughout the scale from low to high interval.

(d)

Answer:

The area of trapezium is (x+11) cm².

Step-by-step explanation:

Given that the formula of area of trapezium is :

[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]

In the formula, a and b represents the length of trapezium and h is the height. So you have to substitute the following expressions into the formula :

[tex]let \: a = 5 \\ let \: b = x + 6 \\ let \: h = 2[/tex]

[tex]area = \frac{1}{2} \times (5 + x + 6) \times 2[/tex]

[tex]area = \frac{1}{2} \times 2 \times (x + 11)[/tex]

[tex]area = 1 \times (x + 11)[/tex]

[tex]area = (x + 11) \: {cm}^{2} [/tex]

Answer:

Area  = x+11

Step-by-step explanation:

[tex]A = \frac{1}{2} (a+b)h\\Base =5\\Height =2\\Base =x+6\\A = \frac{5+(x+6)}{2} \times 2\\A = \frac{5+x+6}{2} \times 2\\ A =\frac{x+11}{2} \times 2\\Area= x+11[/tex]

Answer:

Step-by-step explanation:

Let x be the length and y be the width

The length is 1 inch longer than the width

So : x-1 =y

●●●●●●●●●●●●●●●●●●

The diagonal is 5 inches

The diagonal, width and length are forming a right triangle where the diagonal is the hypotenus

The Pythagorian theorem:

x^2 + y^2 = 5^2

●●●●●●●●●●●●●●●●●●●●●●●

Let's calculate y the width

The system is :

x-1 = y => x =y+1

x^2 + y^2 = 25

Replace x in the second equation with y+1 :

(y+1)^2 + y^2 = 25

y^2 + 2y + 1 + y^2 = 25

2y^2 + 2y +1 = 25

2y^2 + 2y -24 = 0

This is a quadratic equation so we will use the discriminant

●●●●●●●●●●●●●●●●●●●●●●

the discriminat is b^2-4ac

● b =2

● a = 2

● c = -24

b^2 -4ac = 4-4*2(-24) =196 > 0

Since the dicriminant is positive this equation has two solutions y and y'

y = (-2-14)/4 = -16/4 = -4

y '= (-2+14)/4 = 12/4 = 3

The first solution is negative

A distance is always positive so the first solution can't be the width

Then the width is 3

Answer:

Solving equations with fractional or decimal coefficients involves an extra step. To make the equation easier to solve, the first thing you want to do is turn the fractions or decimals into whole numbers. To do so, you either multiply or divide accordingly. When solving equations with integer coefficients and constants, this extra step is not necessary.

Answer:

The number of non-congruent triangles that can be formed by connecting 3 of the vertices of the cube is 3 non-congruent triangles

Step-by-step explanation:

From the three dimensional shape of a cube, triangles can be constructed from;

1) 6 side faces

2) 4 front face to opposite vertices triangles

3) 4 rear face to opposite vertices triangles

Each face can produce ₄C₃ = 4 triangles

Therefore;

The total number of triangles that can be formed = 4 × 6 + 4 × 4 + 4  × 4 = 56 triangles

Of the 56 triangles, it will be found that all 24 triangles from the different 6 direct faces will have the same dimension of 1, 1, √2 are congruent

The 24 triangles formed by the sides of the faces and an adjacent diagonal have the same dimension of 1, √2, √3 and are congruent

The 8 triangles formed by joining the three diagonals have the same dimension of √2, √2, √2 are congruent

Therefore, the 56 triangles comprises of a combination of three non-congruent triangle.

There are only 3 observed non congruent triangles formed by connecting three of the vertices of the cube.

1. 3(x)

2. 3(x+2)

The inverse of the given function is f⁻¹(x) = 3(x + 2).

The inverse function of a function f(x) in mathematics is a function that reverses the operation of f(x).

The given function in the question:

f(x) = (x/3) - 2

f(x) + 2 = x/3

x + 2 = f⁻¹(x)/3

f⁻¹(x) = 3(x + 2)

Hence, the inverse of the given function is f⁻¹(x) = 3(x + 2).

Answer:

m∠B = 107°

Step-by-step explanation:

Since we know that all angles in a triangle add up to 180°, we have

m∠D = 180 - (32 + 41) = 107°

Since we also know by the given picture that both triangles are congruent, we know that the m∠D is equal to m∠B, so m∠B = 107°

Answer:

Choice B.

Step-by-step explanation:

Since h(x) equals (g o f)(x):

f(x) is substituted for x in the equation g(x). We can go through the answer choices and choose the most suitable choice by substitution:

A. f(x) = x, g(x) = x/ x + 1

(g o f)(x) = x / x + 1. This is incorrect.

B. f(x) = x², g(x) = x / x + 1

(g o f)(x) = x² / x² + 1. This matches h(x), so this is correct.

C. f(x) = x + 1, g(x) = 1/x²

(g o f)(x) = 1/(x² + 2x + 1). This is incorrect.

D. f(x) = x + 1, g(x) = x²

(g o f)(x) = x² + 2x + 1. This is incorrect.

Therefore, B is the correct answer.
