i dont know why i am in algebra when I dont understand it, is there anyone out there willing to help me understand it?

Answer:

Step-by-step explanation:

Step one:

given data

we are told that the sales person's earnings is 4% of the sales made.

given that the sales made is $37,000 worth of furnaces.

Step two:

we want to find 4% of $37,000

=4/100*37000

=0.04*37000

=1480

hence for $37,000 the earning will be $1480.

Now suppose sales is doubled that is 37000*2= 74000

we want to find 4% of $74,000

=4/100*74000

=0.04*74000

=2960.

the earnings is $2960.

So if sales doubles the earnings will double

Answer:

We rotate the point counterclockwise by an angle θ = tan⁻¹ (y/x)

Step-by-step explanation:

If we have the point (x, y), its reflection along the x-axis (x,-y). The reflection of the point (x, -y) along the y - axis is (-x, -y). So, the angle between the initial point (x, y) and the final point (-x, -y) is θ = tan⁻¹ [(-y - y)/(- x -x)] = tan⁻¹ [(-2y/(-2x)] =  tan⁻¹(y/x).

So, the point (x, y) is rotated counterclockwise by an angle of  θ = tan⁻¹ (y/x) to perform both reflections.

If m∠5 = x°, according to the Corresponding Angle Theorem, m∠9 will equal the same, and because 9 and 12 are vertical angles, both of these will be the same measure.

Answer:

Step-by-step explanation:

L = 10 - 1.25t

t = 1 ⇒ L = 10 - 1.25 = 8.75 inches

t = 2 ⇒ L = 10 - 1.25(2) = 7.5 inches

t = 3 ⇒ L = 10 - 1.25(3) = 6.25 inches

Answer:

- 81.04°F

Step-by-step explanation:

Given the question :

Convert - 62.8°C into F°

Using the conversion formula :

Fº = 1.8 x Cº + 32º

C = - 62.8°

Fº = (1.8 x - 62.8)+ 32º

F° = - 113.04° + 32°

= - 81.04°F

298ºK is the answer

Cº = 77º - 32º / 1.8 = 25º Kº = 25º + 273 Kº = 298º

Answer:

rational

Step-by-step explanation:

A rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] ← where a and b are integers

Given

2.88

= 2 [tex]\frac{88}{100}[/tex]

= [tex]\frac{2(100)+88}{100}[/tex]

= [tex]\frac{288}{100}[/tex] ← in rational form

Answer:

2.88 is a rational number.

Step-by-step explanation:

A rational number is a number that can be expressed as a ratio or fraction. Since we can write 2.88 as a fraction, (72/25) we know that it is a rational number.

Answer:  (x, y) goes to (1/2x, 1/2y)

Step-by-step explanation:

Answer:

x = 48 degrees

Step-by-step explanation:

Total internal angles:

180 degrees * 3

= 540 degrees

540-105-102-93

= 240

240 = 5x

x = 48

PLS GIVE BRAINLIEST

Answer:

2x = 96º

3x = 144º

Step-by-step explanation:

sum of all angles ina pentagon is 540, so:

2x+3x+105+93+102 = 540

5x+ 300 = 540

5x = 540-300

5x = 240

x = 240/5

x = 48

3x = 48.3

3x = 144

2x = 48.2

2x = 96

proof:

105+93+102+144+96 = 540

a and b

Step-by-step explanation:

Answer:

7. 2b and b are like terms, [tex]b^{6}[/tex] and 3[tex]b^{6}[/tex] are like terms

8. 6 and 7 are like terms, 2n and [tex]\frac{n}{4}[/tex] are like terms

9. m and 2m are like terms, 3³ and 2 are like terms

10. 6³ and 6² are like terms, y³ and 5y³ are like terms

Step-by-step explanation:

Let us solve from No. 7 to No. 10

#7

∵ The terms are 2b, [tex]b^{6}[/tex], b, [tex]x^{4}[/tex], 3[tex]b^{6}[/tex], 2x²

∵ 2b and b have the same variable and the same power

∴ 2b and b are like terms

∵ [tex]b^{6}[/tex] and 3[tex]b^{6}[/tex] have same variable b and same power 6

∴ [tex]b^{6}[/tex] and 3[tex]b^{6}[/tex] are like terms

#8

∵ The terms are 6, 2n, 3n², 6m², [tex]\frac{n}{4}[/tex], 7

∵ 6 and 7 are numerical rational terms

∴ 6 and 7 are like terms

∵ 2n and [tex]\frac{n}{4}[/tex] have the same variable and the same power

∴ 2n and [tex]\frac{n}{4}[/tex] are like terms

#9

∵ The terms are 10k², m, 3³, [tex]\frac{p}{6}[/tex], 2m, 2

∵ m and 3m have the same variable and the same power

∴ m and 2m are like terms

∵ 3³ and 2 are numerical rational terms

∴ 3³ and 2 are like terms

#10

∵ The terms are 6³, y³, 3y², 6², y, 5y³

∵ 6³ and 6² are numerical rational terms

∴ 6³ and 6² are like terms

∵ y³ and 5y³ have the same variable and the same power

∴ y³ and 5y³ are like terms

Lisa: 5 red beads to 3 yellow beads

Tim: 9 red beads to 6 yellow beads

5/3 & 9/6

5/3(2/2) = 10/6

10/6 & 9/6

10/6 > 9/6

10/6 is in fact greater than 9/6. So the answer is no.

Answer:

A) LaTeX: \frac{5}{6} 5 6 feet

Step-by-step explanation:

Kiran has 10 1/2 feet of lumber and wants to make a bookshelf.

Kiran needs two side panels that are each 5 2/3 feet.

1 side panel = 5 2/3 feet

2 side panels =

2 × 5 2/3

2 × 17/3

= 34/3

= 11 1/3 feet

Kiran would need 11 1/3 feet of lumber.

Kiran already has 10 1/2 feet

How much more lumber does Kiran need in order to make the side panels?

This is calculated as:

11 1/3 - 10 1/2

11 - 10 + (1/3 - 1/2)

1 + ( 2 - 3/6)

1 + (-1/6)

1 - 1/6

= 5/6

Hence, Kiran need 5/6 feet more of Lumber.

Answer:

x = 6 , y = 4 , 2 units

Step-by-step explanation:

2y - 6 = y - 2 ⇒ y = 4

3x - 16 = y - 2

3x - 16 = 4 - 2

3x = 18 ⇒ x = 6

Length of sides of square is 2 units

Answer:

3

Step-by-step explanation:

(4p-m)/4

m=-4 and p=2

Since you know what m and p represent, it shouldn't be hard to solve.

(4 [2] - [-4] )/4   The 4 would be positive since there are two negatives.

(8 + 4)/4 Do the work inside the parenthesis first...

(12)/4 now divide.

Answer:

[tex]y = \frac{19}{5} [/tex]

Step-by-step explanation:

[tex] \frac{2y - 4}{y + 7} = \frac{1}{3} [/tex]

or, 3(2y-4) = 1(y+7)

or, 6y-12 = y +7

or, 6y-y = 7+12

or, 5y = 19

or, y = 19/5
