Step-by-step explanation:

If you pay attention to the chart you will notice that medium duty fabric can last from 9000 to 15000 rubs meaning that since fabric B lasted 9200 it would be a medium duty fabric, making Fabric A light duty fabric.

A: This is INCORRECT because fabric B is medium duty

B: This is INCORRECT because Fabric B lasted longer than Fabric A

C: This is CORRECT because Fabric B is medium duty fabric

D:This is CORRECT because Fabric B lasted more rubs than Fabric A because its a more durable fabric

E: This is INCORRECT because Fabric A does not meet the requirements to be a Medium duty fabric.

Answer: $90.00

Step-by-step explanation:

Take this equation

120(n)

n will equal 0.75 since it is 75% of the original price

120(0.75)

$90.00

Answer:

$90

Step-by-step explanation:

75% = 75/100 = 0.75

120*0.75 = 90

Actually Welcome to the Concept of the variables and linear equation.

let the cost of coffee be x and cost of muffin be y.

=> Let the first equation be => 2x + 2y = 16

=> Let the second equation be => 2x + 4y = 20

let's, reduce first eqn ==> x + y = 8 , then x = y-8

now we substitute value of x in second equation,

2(8-y) + 4y = 20

==> -2y + 4y +16 = 20.

==> 2y = 4

==> y = 2

hence, now x = 8-2 ==> 6 ,

so the cost of a Coffee = 6

cost of a muffin = 2

Cost of a muffin = 6

1.) 1

Let's start with 18 degrees and then subtract 12 degrees from it

18-12=6

Now let's take 6 degrees and subtract 5 from it

6-5=1

At 2 pm the temperature was 1 degree.

2.) $125

Start with the total amount John had ($250) and then subtract his remaining amount ($125) to find out how much he withdrew.

Answer:number 5 is 21x−28

Step-by-step explanation:

Answer:

Step-by-step explanation:

The slope intercept form of a line is y=mx+b where m=slope and b=y intercept. So we should solve for y.

3x/5+25y=10, multiply all terms by 5 and the denominator cancels out

3x+125y=50, subtract 3x from each side

125y=-3x+50, divide both sides by 125

y=(-3+50)/125

slope=m=-3/125

y intercept=b=2/5

The side lengths of the triangle are x = 12.375 cm , y = 8.475 cm   .

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.

The basic trigonometric ratios formulas are given below,

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

sec θ = Hypotenuse/Base

cosec θ = Hypotenuse/Perpendicular

cot θ = Base/Perpendicular

According to the question

Hypotenuse of the triangle r = 15 cm

Perpendicular for ∠ θ  =  y

Base for ∠ θ  =  x

sin(θ)=0.565

cos(θ)=0.825

Now, using trigonometric ratio

sin θ = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]

sin(θ)=0.565  (given)

0.565 = [tex]\frac{y}{r}[/tex]

0.565 * r = y

y = 0.565 * 15

y = 8.475 cm  

cos θ = [tex]\frac{Base}{Hypotenuse}[/tex]

cos(θ)=0.825

0.825 = [tex]\frac{x}{r}[/tex]

0.825 * r = x

x = 0.825 * 15

x = 12.375 cm

Hence, the side lengths of the triangle are x = 12.375 cm , y = 8.475 cm.

Answer:

3c+12

Step-by-step explanation:

Are of rectangle = Length * Width

Given the following data

Length: (c+4) ft

Width: 3 ft

Area of the rectangle = 3 (c+4)

Expand

Area of the rectangle = 3(c) + 3(4)

Area of the rectangle = 3c  + 12

hence the expression in simplest form for the area of the rectangle is 3c+12

Answer:

m<2 = 130°

Step-by-step explanation:

m<1 + m<2 = 180° (angles on a straight line/linear pair theorem)

First, we need to find m<2.

m<1 + 90° + 40° = 180° (sum of triangle)

Add like terms

m<1 + 130 = 180

Subtract 130 from each side

m<1 = 180 - 130

m<1 = 50°

Thus:

50° + m<2 = 180°

Subtract 50° from each side

m<2 = 180 - 50

m<2 = 130°

Step 2: Solve for m

Answer:

n = √3

m = √3

Step-by-step explanation:

The triangle is an isosceles right triangle with 2 equal base angles of 45° each.

Thus:

Reference angle = 45°

Hypotenuse = √6

Opposite = m

Adjacent = n

✔️To find m, apply the trigonometric function SOH, we have:

Sin 45 = opp/hyp

Sin 45 = m/√6

√6 × 1/√2 = m (sin 45 = 1/√2)

√6/√2 = m

√(6/2) = m

√3 = m

m = √3

✔️To find n, apply the trigonometric function, CAH:

Cos 45 = adj/hyp

Cos 45 = n/√6

√6 × √2/2 = n (cos 45 = √2/2)

√12/2 = n

√(4*3)/2 = n

(2√3)/2 = n

√3 = n

n = √3
