the sum of 2 consecutive integers is three times their difference what is the larger number
Answer:
2
Step-by-step explanation:
Let the two consecutive integers be x , x+1
Sum : x + x +1 = 2x + 1
Difference: (x +1) - 1 = x + 1 - 1 = x
Sum = 3 times their difference
2x + 1 = 3 * x
2x + 1 = 3x
1 = 3x - 2x
1 = x

Answer:
The area of a square with side length of 2 inches is 4 square inches.
The area of a circle with radius 1.2 inches is:
[tex]\pi \times (1.2) ^{2} \\ = 3.14 \times 1.44 \\ = 4.5216 \: square \: inches[/tex]
That is approximately 4.5 square inches.
Hence, the area of the square (4) is less than {<} that of the circle (4.5)!

all that apply.
13 mm, 5 mm, and 6 mm
2 cm, 7 cm, and 6 cm
2 m, 5 m, and 7 m
6 ft, 6 ft, and 12 ft
The sets of side lengths that can produce a triangle are
2 cm, 7 cm, and 6 cm2 m, 5 m, and 7 m6 ft, 6 ft, and 12 ftThe triangle inequality theorem states that the sum of any two sides of a triangle is greater than or equal to the third side.
That is, in a given triangle of sides a, b and c,
a + b ≥ c
Analysing the sets of the side lengths given,
In triangle 2 cm, 7 cm, and 6 cm,
2 + 6 = 8,
Therefore 8cm which is greater than the third side being 7cm makes this side lengths possible to produce a triangle.
In triangle 2 m, 5 m, and 7 m,
2 + 5 = 7
Addition of both sides of the triangle is equal to the third side being 7m.
In triangle 6 ft, 6 ft, and 12 ft,
6 + 6 = 12
Addition of both sides of the triangle is equal to the third side being 12ft
Therefore the sets of side lengths could produce a triangle are
2 cm, 7 cm, and 6 cm
2 m, 5 m, and 7 m

11. Name the four isosceles triangles in rhombus ABCD.
12. Name three properties of AC and BD.
Answer:
Question 11:
[tex]\angle DAC = 53^\circ[/tex]
[tex]\angle AED = 90^\circ[/tex]
[tex]\angle ADC = 74[/tex]
[tex]DB = 16[/tex]
[tex]AE = 6.03[/tex]
[tex]AC = 12.06[/tex]
Question 12:
[tex]\triangle ABD[/tex], [tex]\triangle BAC[/tex], [tex]\triangle CDA[/tex] and [tex]\triangle DAB[/tex]
Question 13:
AC and BD are perpendicular lines, and they are diagonals
Step-by-step explanation:
Question 11
Given
[tex]\angle BAC = 53^\circ[/tex]
[tex]DE = 8[/tex]
See attachment for Rhombus
Required
Determine the indicated sides
Solving (a): [tex]\angle DAC[/tex]
Diagonal CA divides [tex]\angle DAB[/tex] into 2 equal angles
i.e
[tex]\angle DAC = \angle BAC[/tex]
So:
[tex]\angle DAC = 53^\circ[/tex]
Solving (b): [tex]\angle AED[/tex]
The angles at E is 90 degrees because diagonals AC and BD meet at a perpendicular.
So:
[tex]\angle AED = 90^\circ[/tex]
Solving (c): [tex]\angle ADC[/tex]
First, we calculate [tex]\angle ADE[/tex], considering [tex]\triangle ADE[/tex]:
[tex]\angle ADE + \angle AED + \angle DAC = 180[/tex]
[tex]\angle ADE + 90 + 53 = 180[/tex]
[tex]\angle ADE + 143 = 180[/tex]
[tex]\angle ADE = -143 + 180[/tex]
[tex]\angle ADE = 37[/tex]
To calculate [tex]\angle ADC[/tex], we have:
[tex]\angle ADC = 2*\angle ADE[/tex]
[tex]\angle ADC = 2* 37[/tex]
[tex]\angle ADC = 74[/tex]
Solving (d): [tex]DB[/tex]
From the rhombus
[tex]DB = DE +EB[/tex]
Where
[tex]DE =EB[/tex]
So:
[tex]DB = 8 + 8[/tex]
[tex]DB = 16[/tex]
Solving (e): [tex]AE[/tex]
To do this we consider [tex]\triangle ADE[/tex]
Using the tan formula
[tex]tan(\angle ADE) = \frac{AE}{DE}[/tex]
[tex]\angle ADE = 37[/tex] and [tex]DE = 8[/tex]
So:
[tex]\tan(37) = \frac{AE}{8}[/tex]
[tex]AE = 8 * \tan(37)[/tex]
[tex]AE = 6.03[/tex]
Solving (f): [tex]AC[/tex]
This is calculated as:
[tex]AC = AE + EC[/tex]
Where
[tex]AE = EC[/tex]
[tex]AC = 6.03 +6.03[/tex]
[tex]AC = 12.06[/tex]
Question 12: Isosceles Triangle
In the rhombus, all 4 sides are equal;
So, the isosceles triangle are:
[tex]\triangle ABD[/tex], [tex]\triangle BAC[/tex], [tex]\triangle CDA[/tex] and [tex]\triangle DAB[/tex]
Question 13:
AC and BD are perpendicular lines, and they are diagonals

The sum of the polynomials is 3x² + 6x + 4.
What are Polynomials?Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.
Given are two polynomials whose sum has to be found.
(6x + 7 + x ²) and (2x² - 3).
The sum of the polynomials is,
(6x + 7 + x ²) + (2x² - 3)
We have to operate the like terms together.
= (6x) + (7 - 3) + (x² + 2x²)
= 6x + 4 + 3x²
= 3x² + 6x + 4
Hence the sum of the polynomials is 3x² + 6x + 4.

Answer:
13 inches
Step-by-step explanation:
A clarinet case is shaped like a rectangular prism the case is 8 inches tall 3 inches wide and has a volume of 312 cubic inches what is the length of the clarinet case
The volume of a rectangular prism = Length × Width × Height
Length of the rectangular prism = Volume/ Width × Height
= 312 in³/ 3 in × 8 in
= 312 in³/24 in²
= 13 in
Length = 13 inches

Hank and Rosa play the following game: A bag has 15 tiles in it, each with a letter from the phrase probability game on it. Hank and Rosa take turns drawing a tile, recording the letter, and placing the tile back in the bag. Hank earns a point if he draws a vowel. Rosa earns a point if she draws a consonant. They decide that the letter y can be a vowel or a consonant. Which statement best explains whether or not the game is fair?
A. The game is not fair because the probability of Hank drawing a winning letter is less than the probability of Rosa drawing a winning letter.
B. The game is fair because Hank and Rosa have the same probability of drawing a winning letter.
C. The game is fair because both Hank and Rosa will get a point if the letter y is drawn.
D. The game is not fair because the probability of Hank drawing a winning letter is greater than the probability of Rosa drawing a winning letter.
Answer:
A
Step-by-step explanation:
There are 8 consonants (not including y) and only 6 vowels (not including y), so Rosa has a higher probability of winning.
The game is not fair because the probability of Hank drawing a winning letter is less than the probability of Rosa drawing a winning letter.
What is probability?
'Probability is defined as the possibility of an event to happen is equal to the ratio of the number of outcomes to the total number of outcomes.'
According to the given problem,
There are 8 consonants (not including y) and only 6 vowels (not including y), so Rosa has a higher probability of winning.
Hence, we can conclude that the game is not fair the probability of Hank drawing a winning letter is less than the probability of Rosa drawing a winning letter.
