Need Help, with steps

**Answer:**

It is **C**

**Step-by-step explanation:**

PM = QM

[tex]6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3[/tex]

**Answer:**

C.) x = 3

**Step-by-step explanation:**

The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.

The GCF of two numbers is 3.

Their LCM of the two numbers is less than 20.

Which could not be the two numbers?

**Answer:**

**Step-by-step explanation:**

Let say a and b the 2 natural integers with 0 < a< b.

Since a*b=GCF(a,b)*LCM(a,b)

a*b < 3*20=60

Citydog Screen Printers received two orders for a t-shirt designed for a math symposium. The first order was for 40 shirts at a total cost of $295 and the second order was for an additional 80 shirts at a total cost of $565. Each order included a shipping and handling charge.

1.Write the linear equation that models the equation?

2.What is the cost per T-shirt?

3.What is the standard shipping and handling bag?

**Step-by-step explanation:**

Citydog Screen Printers received two orders for a t-shirt designed for a math symposium. The first order was for 40 shirts at a total cost of $295 and the second order was for an additional 80 shirts at a total cost of $565. Each order included a shipping and handling charge.

Then we have to writer a linear equation, for which I got: y-27/4x+25. We also had to find the cost per t-shirt, for which I got: $31.75. The last part I don't understand, however: fidn the shipping and handling charge.

The second word problem is:

It costs Consolidated Cereals Corporation $1050 to produce 100 boxes of corn flakes and $1250 to produce 500 boxes. I found the cost function: c(x)=1/2x+1000 but don't know how to determine the fixed cost and the variable cost per box (mainly because I have no idea what those are.)

Cost= m x+b

x is the cost per shirt, b is the handling charge

295=40m+b

565=80m+b

subtract the first equation from the second:

370=40x solve for m, the cost of each shirt. Then solve for b, put all that into y= mx+b

One the second question,

Cost= variable cost * n + Fixedcosts or

cost= n*v+F

1250=500v+f

1050=100v+f

subtract the second equation from the first

200=400v solve for v, and it is 1/2 dollar. Solve for f, the fixed cost, and it looks as if it is 1000 dollars.

Point W is on line segment V X. Given VX = 18 and VW = 14 determine the length W X

**Answer: WX = 4**

**Concept:**

Here, we need to know the idea of segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

**Solve:**

Given information

VX = 18

VW = 14

Given expression deducted from the segment addition postulate

WX = VX - VW

Substitute values into the expression

WX = 18 - 14

Simplify by subtraction

WX = 4

Hope this helps!! :)

Write an equation in slope-intercept form of a line that passes through the point (-4,9) and has a slope of 1/2.

**Answer:**

y = 1/2x + 11

**Step-by-step explanation:**

y = 1/2x + b

9 = 1/2(-4) + b

9 = -2 + b

b = 11

What is 3(x-6)+12=6(x+1)-3x show your work.

**Answer:**

No solution.

**Step-by-step explanation:**

3(x - 6) + 12 = 6(x + 1) - 3x

3x - 18 + 12 = 6x + 6 - 3x

3x - 6 = 3x +6

-6 = 6

-6 ≠ 6

How many meters does a runner cross in a circular runway with radious of 100 meters [R=3, 14]

diameter = 2 * radius = 200m

circumference (length of the outside of the circle = diameter * pi = 200 * 3.14

= 628m

circumference (length of the outside of the circle = diameter * pi = 200 * 3.14

= 628m

The length of each side of an equilateral triangle having an area of 9√3 cm² is

**Answer:**

6 cm

**Step-by-step explanation:**

Let each side of the equilateral triangle be *a*.

Given, area of an equilateral triangle = 9√3 cm2

Area of an equilateral triangle = (√3)/4 × (Side)²

=> (√3)/4 × a² = 9√3

[tex] {a}^{2} = \frac{9 \sqrt{3} }{ \frac{ \sqrt{3} }{4} } = \frac{9 \sqrt{3} }{ \sqrt{3} } \times 4 = 9 \times 4[/tex]

=> a² = 36

[tex] \sqrt{ {a}^{2} } = \sqrt{36} \\ a = (+ - )6[/tex]

∴ Side = 6 cm [taking positive square root because side is always positive]

another easy question pls answer

**Answer:**

22.5 degrees and 67.5 degrees

**Step-by-step explanation:**

complementary angles add up to 90°

x + 3x = 90°

4x = 90

90/4 = x

x = 22.5

The first angle is 22.5

The second angle is 3 times as much

22.5 x 3 = 67.5

Hi ;-)

[tex]s=zh-2zt^3\\\\z(h-2t^3)=s \ \ /:(h-2t^3)\\\\z=\dfrac{s}{h-2t^3}[/tex]

**Answer:**

z = [tex]\frac{s}{h-2t^3}[/tex]

**Step-by-step explanation:**

Given

s = zh - 2zt³ ← factor out z from each term

s = z(h - 2t³ ) ← divide both sides by h - 2t³

[tex]\frac{s}{h-2t^3}[/tex] = z

suppose a 13 foot ladder is leaning against a building. Reaching to the bottom of a second floor window 12 ft above the ground. How far is the base of the ladder from the building? Round your answer to the nearest 10th

5 ft

4ft

3ft

6ft

**Answer: First Choice. 5ft**

**Step-by-step explanation:**

Here we need to know the idea of the Pythagorean theorem.

Since a building is straight, the base angle is a right angle, thus it would be a **right triangle**.

Pythagorean Theorem: a² + b² = c²

**NOTE** Please refer to the attachment below for the figure. (I drew it, so if it was not clear and understandable for you, please tell me.)

**Solve:**

Given information

a = 12 ft

c = 13 ft

b = unknow base length

Given formula for Pythagorean Theorem

a² + b² = c²

Substitute values into the formula

12² + b² = 13²

Simplify exponents

144 + b² = 169

Subtract 144 on both sides

144 + b² - 144= 169 - 144

b² = 25

Square root both sides

√b² = √25

Sin A 4/5.

Find

COSA + tan A

**Answer:**

**Step-by-step explanation:**

The opposite side (the one not connected to A) = 4

The hypotenuse is 5

The adjacent side needs to be found for the cosine and the tangent.

a^2 + b^2 = c^2

a = opposite side = 4

b = adjacent side = ?

c = hypotenuse = 5

4^2 + x^2 = 5^2

16 + x^2 = 25

x^2 = 25 - 16

x^2 = 9

x = sqrt(9)

x = 3

cos(A) = adjacent / hypotenuse = 3/5

Tan(A) = opposite / adjacent = 4/3

cos(A) + tan(A) = 3/5 + 4/3

cos(A) + tan(A) = 9/15 + 20/15 = 29/15

Given: SinA = 4/5

To find: CosA + TanA

Solution:

16/25 + Cos²A = 1 [Sin²A + Cos²A = 1]

Cos²A = 1 - 16/25

Cos²A = 25 - 16/25

Cos²A = 9/25

CosA = 3/5

We know that TanA = SinA/CosA

TanA = (4/5)/(3/5)

TanA = 4/3

CosA + TanA = 3/5 + 4/3 = 29/15

To find: CosA + TanA

Solution:

16/25 + Cos²A = 1 [Sin²A + Cos²A = 1]

Cos²A = 1 - 16/25

Cos²A = 25 - 16/25

Cos²A = 9/25

CosA = 3/5

We know that TanA = SinA/CosA

TanA = (4/5)/(3/5)

TanA = 4/3

CosA + TanA = 3/5 + 4/3 = 29/15
