Brittney has 2 and 3/4 yards of fabric. She wants to make wreaths that require 1/8 yards. What is the maximum number of wreaths she can make?
Answer: 22
Step-by-step explanation:
Given
Brittney has 2 and [tex]\frac{3}{4}[/tex] yards of fabric
Converting it to a fraction
[tex]\Rightarrow 2\ \dfrac{3}{4}=\dfrac{8+3}{4}\\\\\Rightarrow \dfrac{11}{4}[/tex]
Wreath require [tex]\frac{1}{8}[/tex] yards
Number of wreaths that can be made
[tex]\Rightarrow n=\dfrac{\frac{11}{4}}{\frac{1}{8}}\\\\\Rightarrow n=\dfrac{11}{4}\times \dfrac{8}{1}\\\\\Rightarrow n=22[/tex]
She can make 22 wreaths

Find the perimeter of the figure to the nearest hundredth.
Answer:
61.68cm
Step-by-step explanation:
Perimeter of the semicircle = 2πr
r is the radius = 12/2 = 6cm
Perimeter of the semi circle = 2(3.14)(6)
Perimeter of the semi circle = 37.68cm
Adding the remaining sides of the polygon
Perimeter of the figure = 37.68+ 10 + 6 + 8
Perimeter of the figure = 61.68cm
Hence the perimeter of the figure is 61.68cm

Option BStep-by-step explanation:
Given function:
H(s) = 0.003s² + 0.07s - 0.027Average rate of change in the interval s = 80 and s = 100:
[H(100) - H(80)] / (100 - 80) = [0.003(100²) + 0.07(100) - 0.027 - 0.003(80²) - 0.07(80) + 0.027] / 20 = 12.2 / 20 = 0.61Correct choice is B. 0.61

Answer:
Step-by-step explanation:
Complete the square
[tex]x^{2}[/tex] + 2x - 13 = 0
[tex]x^{2}[/tex] + 2x = 13
[tex]x^{2}[/tex] + 2x + [tex]1^{2}[/tex] = 13 +1 (take 1/2 of the b term , the 2 )
[tex]x^{2}[/tex] + 2x + 1 = 14
(x +1)^2 = 14
Answer:
Complete the square:
x² + 2x - 13 = 0x² + 2x + 1 - 14 = 0(x + 1)² - 14 = 0(x + 1)² = 14x + 1 = ± √14x = -1 ± 3.74x = 2.74, x = -4.74Which expressions are equivalent to 2.25x ?

Answer:
The correct answer is [tex]108\pi (yd^3)[/tex].
Step-by-step explanation:
The formula to find a volume of a cone is [tex]\pi r^2*\frac{h}{3}[/tex], where [tex]r[/tex] represents the radius and [tex]h[/tex] represents the height of the cone. By substituting the values in, you'll get that the volume of the cone is equivalent to [tex]\pi*6^2*\frac{9}{3}[/tex] = [tex]36\pi * 3[/tex] = [tex]108\pi (yd^3)[/tex], so that is the answer.
Answer:
108 cu. yd.
Step-by-step explanation:
V = [tex]\frac{\pi r^{2} h}{3}[/tex] = [tex]\frac{ \pi 6^{2} *9}{3}[/tex] = [tex]\frac{36(9)\pi }{3}[/tex] =[tex]\frac{ 324\pi }{3}[/tex] = 108 cu. yd.

Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
Step-by-step explanation:
180° = m∠A + m∠B + m∠C
180° = 85° + 53° + m∠C
180° = 138° + m∠C
m∠C = 180° - 138°
= 42°

In a computer catalog, a computer monitor is listed as being 27 inches. This distance is
the diagonal distance across the screen. If the screen measures 15 inches in height,
what is the actual width of the screen to the nearest inch?
Answer:
The actual width of the screen = 22.45 inches
Step-by-step explanation:
From the above question, we are given the following parameters
Diagonal = 27 inches
Height (Length) = 15 inches
Width = ???
To solve this question we would be using Pythagoras Theorem.
Diagonal² = Length² + Width²
Width² = Diagonal² - Length²
Width = √Diagonal² - Length²
Width = √27² - 15²
Width = √729 - 225
Width = √(504)
Width = 22.449944321 inches
Approximately to the nearest inch,
The actual width of the screen = 22.45 inches

Answer:
146 mm²
Step-by-step explanation:
First, let's start with the formula for the surface area of a rectangular prism.
A = 2(wl + hl + hw)
Plug in everything that you know.
A = 2[(4 · 5) + (7 · 5) + (7 · 4)]
Simply the equation.
A = 2(20 + 35 + 28)
A = 2(73)
A = 146

What equation do I write for a line that has a y intercept of 2 and is perpendicular to y=2/3x+4?
Answer:
y = -3/2x + 2
Step-by-step explanation:
The equation has the format y = mx + b where m is the slope and b is the y-intercept.
The question gives you the y-intercept, so b = 2.
As for the slope, you need the fact that perpendicular lines have slopes that are opposite ("negative") reciprocals of each other.
The slope of the line given in the question is 2/3. The opposite reciprocal of 2/3 is - 3/2.
The equation for the line is y = -3/2x + 2
-3.5x + 8.5x - 4 =26
Answer:
x = 6
Step-by-step explanation:
-3.5x + 8.5x - 4 = 26
-3.5 + 8.5x = 26 + 4
5.0x = 30
x = 30/5
x = 6
Answer:
x=6
Step-by-step explanation:
First, add -3.5x and 8.5x to combine like terms, which would then look like 5x-4=26.
Next, add 4 to both sides of the equation, which would then be 5x=30.
Finally, divide both sides of the equation by 5 and then simplify.
The final answer would be x=6.

In ΔUVW, w = 5.3 inches, v = 3.6 inches and ∠V=32°. Find all possible values of ∠W, to the nearest 10th of a degree. Answer: 51.3∘ and 128.7∘ DeltaMath
Answer:
Answer: 51.3∘ and 128.7∘
Step-by-step explanation:
In ΔUVW, w = 5.3 inches, v = 3.6 inches and ∠V=32°. Find all possible values of ∠W, to the nearest 10th of a degree.
We solve the above question using sine rule formula. This is given as:
w/sin W = v/sin V
w = 5.3 inches
v = 3.6 inches
∠V=32°.
5.3/sin W = 3.6/sin 32
Cross Multiply
sin W × 3.6 = 5.5 × sin 32
sin W = 5.5 × sin 32/3.6
W = arc sin (5.5 × sin 32/3.6)
W = 51.28° or 128.72°
Approximately
= 51.3° or 128.7°
Answer:
128.7
