Answer:
3 pieces
Step-by-step explanation:
Given: Figure
To find: Number of 8.5 in. × 11 in. pieces used to cover the floors of a room and a hallway in her dollhouse
Solution:
In the given figure, AC = 22 in.
AB + BC = 22 in.
AB + EF = 22 (As BC = EF being opposite sides of rectangle)
AB + 10 = 22
AB = 22 - 10 = 12 in.
Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches
(area of rectangle = length × breadth )
CE = CD + DE = AH + GF (As CD = AH and DE = GF)
CE = 5 + 15 = 20 inches
Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches
(BC = EF = 10 in.)
Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches
Area of pieces of felt = 8.5 × 11
So,
Number of pieces required = Total area of the figure / Area of pieces of felt = 3 pieces

Answer:
Area of circle - Area of square
radius of circle is 8m
side of squre os 12m
Step-by-step explanation:
Area of circle is pie r^2
22/7 × 8 × 8
22/ 7 × 64
= 201.14m^2
Area of square is side ^2
12 ×12
= 144m^2
hence 201.14 - 144
= 57.14m^2 is the area of shaded figure

Answer:
[tex]x=\frac{21}{4}[/tex]
[tex]y=\frac{21}{2}[/tex]
Step-by-step explanation:
equation (1): [tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]
equation (2): y=2x
solve the system by substitution
step1: sub (2x) for y in equation 1:
[tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]
[tex]\frac{1}{2} (2x+2x)=\frac{21}{2}[/tex]
step2: simplify the expression:
[tex]\frac{1}{2} (4x)=\frac{21}{2}[/tex]
[tex]2x=\frac{21}{2}[/tex]
(divide by 2 for both sides)
[tex]x=\frac{21}{4}[/tex]
To find the value for y sub 21/4 for x in equation 2:
y=2x
y=2×(21/4)
[tex]y=\frac{21}{2}[/tex]

Read the excerpt from "The Tell-Tale Heart."
Which statement best explains how the reader can
determine that the narrator is unreliable?
But you should have seen me. You should have seen
how wisely I proceeded—with what caution—with what
foresight—with what dissimulation I went to work! I was
never kinder to the old man than during the whole week
before I killed him. And every night, about midnight, I
turned the latch of his door and opened it-oh so
gently! And then, when I had made an opening
sufficient for my head, I put in a dark lantern, all closed,
closed, that no light shone out, and then I thrust in my
head. Oh, you would have laughed to see how
cunningly I thrust it in!
O The narrator is very kind to the old man during the
whole week before the murder.
O The narrator checks on the old man every night at
midnight to ensure his well-being.
O The narrator closes the lantern tightly so the old
man is not awakened by the bright light.
O The narrator believes that his audience will approve
of and even laugh at his plot to murder the old man.
Answer:
The narrator checks the old man at every night at midnight

Mike installed the window shown. How many square feet is the window? Use 3.14 for pi. Round to the nearest tenth.
Answer: 3.9ft²
Step-by-step explanation:
Find the area of the rectangle first:
= Length * Width
= 2 * 1.5
= 3 ft²
Find the area of the semi-circle by finding the area of a circle and dividing it by 2:
= πr²
= 3.14 * 1.5/2 * 1.5/2
= 1.76625ft²
Divide by 2:
= 1.76625/ 2
= 0.88 ft²
Add the area of the rectangle to the semi-circle:
= 3 + 0.88
= 3.9ft²
A 8-kg load stretches an elastic belt 0.02 m. How much will a 12-kg load stretch the belt?
Answer:
A 12-kg load stretches an elastic the belt 0.03m
Step-by-step explanation:
we know A 8-kg load stretches an elastic belt 0.02 m.
=> 0.02 / 8 = 0.0025
so A 1-kg load can stretch an elastic belt 0.02 m.
=> 12 * 0.0025 = 0.03 m
A 12-kg load stretches an elastic the belt 0.03m

FIND BC
round to the nearest HUNDREDTH
Answer:
CB = 30.15
Step-by-step explanation:
180-58-93 = 29 degrees for angle B
draw a line perpendicular to BC down to point A, lets call the perpendicular point D.
now you've got 2 similar, smaller triangles
angle A is split into two angles, 29 degrees above and 58 degrees below.
sin 29 =CD/16
CD = 7.75
cos 29 = AD/16
AD = 14
tan 58 =DB/AD = DB/14
DB = 22.40
CD + DB = 7.75 + 22.40 = 30.15
Which equation is equivalent to
1/5x-3=2/3
A 5X-45=3
B 3x - 15=10
C 3x-45 = 10
D X-15 = 10
Answer:
c) 3x - 45 = 10
Step-by-step explanation:
[tex]\frac{1}{5}x-3=\frac{2}{3}\\\\\frac{1}{5}x-\frac{3*5}{1*5}=\frac{2}{3}\\\\\frac{x-15}{5}=\frac{2}{3}\\[/tex]
Cross multiply,
3*(x - 15) = 2*5
3*x - 3*15 = 10
3x - 45 = 10

Any helppp pLeAsE? T^T
answer:
c = 7.6 kilometers
step-by-step explanation:
you can use the pythagorean theorem for this since this is a right triangleknow the formula: a^2 + b^2 = c^2now plug in what we know, also remember:
a = legb = the other legc = hypotenusea^2 + b^2 = c^2
3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
c = 7.6157
rounded: c = 7.6 kilometers

Answer: C. [tex]\sqrt[3]{5}[/tex]
Step-by-step explanation: Plato/ Edmentum
The simplified form of square root 45 is 3√5. Therefore, the correct answer is option C.
The given number is √45.
The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.
Here, factors of 45 = 3×3×5
√45 = √3×3×5
= 3√5
Therefore, the correct answer is option C.
