amy uses 2/3 of a yard of fabric for each pillow she makes. she has 5 yards of fabric. does she have enough to make 8 pillows

Answer:

0 < x < 6

Step-by-step explanation:

triangle sides:

other sides subtracted < third side < other sides added

4-3 < x+1 < 4+3

1 < x+1 < 7

1-1 < x+1-1 < 7-1

0 < x < 6

Hope this helps :)

The value of the measure of angle B will be;

⇒ ∠ B = 87.13°

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The value is,

⇒ cos B = 0.05

Now,

Since, The value is,

⇒ cos B = 0.05

Taking cos inverse both side, we get;

⇒ cos⁻¹ cos B = cos⁻¹ 0.05

⇒ B = 87.13°

Thus, The value of angle B = 87.13°

Complete question:

Ren built a birdhouse with a volume of 224 in³ Find the height of the birdhouse. A square pyramid. The square base has side lengths of 8 inches and the height is unknown.

Answer:

the height of the birdhouse is 10.5 in.

Step-by-step explanation:

Given;

volume of the square pyramid, V = 224 in³

length of a side of the square base, a = 8 in

The volume of square pyramid is calculated as;

[tex]V = \frac{a^2h}{3} \\\\where;\\h \ is \ height \ of \ the \ birdhouse \ (Pyramid)\\\\a^2h = 3V\\\\h = \frac{3V}{a^2} \\\\h = \frac{3 \times 224}{8^2} \\\\h = 10.5 \ in[/tex]

Therefore, the height of the birdhouse is 10.5 in.

Answer:

Cost of article before tax is 120.

Step-by-step explanation:

It says cost of an article including 15% tax is 138.

So, let the cost of article without tax as 'x'

So, we can set up equation as

x+15%(x)=138

Simplify it

x+0.15x=138

1.15x=138

Divide both sides by 1.15

x=120

So, cost of article before tax is 120.

Answer:

The lines are perpendicular.

Step-by-step explanation:

If the lines are parallel, then the slopes are equal

If the lines are perpendicular, then the slopes are negative reciprocals

If neither of the above occur, then the lines are neither parallel or perpendicular.

y = 2x + 3  is in slope-intercept form, so the slope = 2

2y + x = 6

Solve for y:    2y = -x + 6

                        y = -1/2(x) + 3    so the slope = -1/2

2 and -1/2 are negative reciprocals, so the lines are perpendicular.

Note:  Negative reciprocals have a product of -1.  2(-1/2) = -1

yes

Answer:

26ft

Step-by-step explanation:

Complete Question:

The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet. Find its length

Formula for calculating the area of a rectangle is expressed as shown;

Area of a rectangle = Length * Width

Given the equation a = 26w that gives the area of a rectangle

On comparing with the formula;

Length * Width = 26w

Length = 26ft (by comparison)

Hence the length of the rectangle is 26ft

Answer:

210in^3

Step-by-step explanation:

Given data

Dimension

Length= 5in

Width= 6in

Height= 7in

The expression for the volume of a rectangle is given as

Volume= L*W*H

Substitute

Volume= 5*6*7

Volume= 210in^3

Answer:

no, because the first=12-x

and the second=-1x+2

Step-by-step explanation:

Answer:

No, they are not equivalent.

Step-by-step explanation:

First, we simplify the two expressions.

3(4 - x) = 12 - 3x  We multiply everything inside the bracket by 3.

6(x + 2) - 7x = 6x + 12 - 7x = 12 - x  Using BODMAS/BIDMAS, we first multiply everything in the brackets by 6 and then simplify.

If we compare 12 - 3x to 12 - x, we can clearly notice that they aren't equivalent. If they were to be equivalent, they would have to be exactly the same values as each other. The 12 is common in both expressions, but the -3x and -x differ, therefore the following two expressions aren't equivalent.
