Answer:

$7.87

Step-by-step explanation:

Step one:

given data

For each costume, he needs 2.125 yards of fabric

cost of Fabric is $3.49 a yard

Required

The total cost of making the costume

Step two:

Hence the total cost of fabric needed is = 2.125*3.49= $7.42

sales tax is 6%

= 6/100*7.42

= 0.06*7.42

=$0.45

Therefore total cost of the costume is = 7.42+0.45= $7.87

Answer:

C. l = hk

Step-by-step explanation:

the equation for direct variation is y = xk (or y/x = k) so you just replace y and x with l and h

The length of the shadow cast l represents by situation l = hk. Hence, option (C) is correct.

An equation has a linear relation if a variable from that equation varies linearly with the other variable.

for example, x is varied linearly with y then we can write

x ∝ y

x = yk where k will be the constant of variation.

Given that length, l is varies directly as the height h

Hence, l = hk will be the correct representation.

Answer:

r =5

Step-by-step explanation:

-4x - 12 = 8

     + 12  +12

-4x = 20

-4     -4

x = -5

To ensure that x equals -5, let's substitute the negative integer with x.

-4 x -5 - 12 = 8

-20 - 12 = 8

8 = 8

Therefore, the answer is x = -5 because we confirmed our answer by substituting x with -5 and solving the equation and got the both sides of the equation equal.

The solution to the equation -4x - 12 = 8 is x = -5.

To solve the equation -4x - 12 = 8, we'll isolate the variable x by performing the necessary steps.

First, we'll add 12 to both sides of the equation to eliminate the constant term on the left side:

-4x - 12 + 12 = 8 + 12

This simplifies to:

-4x = 20

Next, we'll divide both sides of the equation by -4 to isolate x:

(-4x)/-4 = 20/-4

This yields:

x = -5

Hence, the solution to the equation -4x - 12 = 8 is x = -5.

By performing the necessary operations of addition, subtraction, and division, we have determined that x is equal to -5, satisfying the equation. This can be verified by substituting x = -5 back into the original equation and confirming that both sides are equal.

Step-by-step explanation:

Challenge # 1

Line has a negative slope with positive slope.

Therefore, equation will be,

y = 1.5x - 6

Parallel line to the given line will have same slope = 1.5 but with different y-intercept.

Equation of the parallel line → y = 1.5x + 6

Challenge # 2

Line has a negative y-intercept = -1 (Approx.)

Slope of the line = negative

Therefore, equation of the line will be,

y = -3.7x -1

Line parallel to the given line will have same slope but different y-intercept.

Equation of the parallel line → y = -3.7x + 1

Challenge # 3

Line with negative slope and no y-intercept.

y = -0.8x

Parallel line to the given line will have same slope and different y-intercept.

Equation of the parallel line → y = -0.8x + 1

Challenge # 4

Line in the graph has positive slope and negative y-intercept.

y = -5 + 4.2x

Line parallel to the given line will have same slope but different y-intercept.

Equation of the parallel line → y = - 7 + 4.2x

Step-by-step explanation:

Answer:

Option 2

Step-by-step explanation:

We will use the substitution method, as the question asks for. The second equation (where x or y is isolated on one side) will be susbstituted as the x or y in the first equation.

2x-3y=-29

x+4y=13

let's isolate x onto one side in the second equation.

Subtract 4y from both sides

x=-4y+13

now we can substitute the expression as x in the first equation

2(-4y+13)-3y=-29

it's the 2nd option

Answer:

The maximum distance between posts is 8 m

Step-by-step explanation:

There is a rectangle-shaped plot where we have to place equidistant posts at the maximum possible distance. The dimensions of the plot are 608 m and 264 m.

The maximum distance between posts is given by the maximum possible divisor of 608 and 264. That number is called the greatest common divisor (GCD).

It can be found by factoring both numbers:

[tex]608 = 2^5*19[/tex]

[tex]264 = 2^3*33[/tex]

The GCD is the product of all common factors with the least exponent. The only common factor is 2 and the least exponent is 3. Thus the GCD is 2*2*2=8.

Distance between points [tex](a,b)\,,\,(c,d)[/tex] is given by [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]

The trail starts at P(−2, 2) and goes to Q(5, 2).

[tex]PQ=\sqrt{(5+2)^2+(2-2)^2}=\sqrt{7^2}=7[/tex] units

It goes from Q to R(5, −5)

Take [tex](a,b)=(5,2)\,,\,(c,d)=(5,-5)[/tex]

[tex]QR=\sqrt{(5-5)^2+(-5-2)^2}=\sqrt{(-7)^2}=7[/tex] units

It goes from R to S.

Take [tex](a,b)=(5,-5)\,,\,(c,d)=(8,-5)[/tex]
