Answer:
103.62
Step-by-step explanation:
a = πr^2
Area large circle
a = π7²
a = π(49)
a = 153.86
Area inner circle
a = π4²
a = 50.24
Area shaded = large cicle - inner circle
a = 153.86 - 50.24
a = 103.62
Dennis and Eduardo are studying transformations using triangles. A ABC and A DEF are both plotted on a coordinate plane
Dennis notices that if he reflects A ABC across the y-axis and then translates it down 4 units, the result is A DEF.
Eduardo says that he can first translate A ABC down 4 units and then reflect it across the y-axis in order to get A DEF.
Is Eduardo correct? Explain your answer and tell whether A ABC and A DEF are congruent.
Type your answer in the box below.
Answer:
i think they are
Step-by-step explanation:
The translation of the 4 units right then a reflection across the x-axis will map triangle ABC onto triangle DEF.
What are the translation and reflections of an image?Translation of an image indicates the horizontal or vertical movement of that image. The reflection of an image indicates the mirror image of the given image along with a fixed-line.
Here, when we translate the triangle ABC to the right by 3 units, then point A will be at (2, 6), point B will be at (2, 3), and point C will be at (4, 3.).
Hence, after reflecting the triangle ABC, we get the triangle DEF.

QUESTION: Find the value for x for the diagram below. Explain how you got your answer
Answer:
x = 2.8 units
Step-by-step explanation:
volume = width x length x height
23.52 = 1.5 x 5.6 x height
height = 23.52/(1.5 x 5.6) = 23.52/8.4 = 2.8 units
A box containing a present is shown.
How much wrapping paper is needed to wrap the present?
A. 41 in2
B. 82 in2
C. 11.5 in2
D. 44 in2
The answer is:
D. 44in2
Answer:
82 in²
Step-by-step explanation:
Surface area =
2(5.5x4) in² + 2(5.5x2) in² + 2(4x2) in²
= 44 in² + 22 in² + 16 in²
= 82 in²

what's the missing measurement ? pls help :]
Answer:
first one: 33 degress
second one: 67 degrees
Step-by-step explanation:
the total measurement for every triangle is 180 so js add up what they give you and subtract it from 180.
hope this helps
Answer:
Step-by-step explanation:
Sum of all angles of a triangle = 180
1) 60 + 87 + b = 180
147 + b = 180 {Subtract 140 from both sides}
b = 180 - 147
b = 33
2) b + 83 + 30 = 180
b + 113 = 180 {Subtract 113 from both sides}
b = 180 - 113
b = 67
Samantha went to a bike store to purchase a new bike. The store was having a sale. If the total purchase, not including tax was over $200, you got 25% off your purchase. And, if your total was over $250, you got 30% off your purchase. Samuel picked out a bike for $189, two t-shirts for $28 each, and a water bottle for $5.50. What was his total purchase price before tax?
Answer: 250.2
Step-by-step explanation: 250.50 divided by 30% = 0.30 Meaning subtract 30 cents from 250.5

Answer:
108
Step-by-step explanation:
So, to start, we can calculate the fuel used in March by using the following equation:
(40x240)/100
Which is 96. So the furnace burned 96 gallons of fuel in March and was left with 144 gallons. Now we need to find out how much of its remaining fuel it burned in April, so we use this:
(25x144)/100
Which is 36. So it burned another 36 gallons of fuel in April, leaving it with 108 gallons still in the tank.
Answer: i think is 108 i hope this help sorry.....

Answer:
question 5 = 167.5ft^3 so yeah correct
question 6 = the 4th answer = 2388ft^3
Volume using full pi = ; 2389.2ft^3 or 2389 ft^3 to 4sf.
Step-by-step explanation:
question 6 =
We have 13 Diameter. Which is 6.5 radius
D = 13
R = 6.5
H = 18
Surface area a of cylinder pi x 6.5^2 = 132.73229
or 42.25pi
Then we just multiply by the height to get the volume.
42.25x 18 = 760.18 pi
or 132.73229 x 18 =2389.18122
Volume = 2389.2ft^3 or 2389 ft^3 to 4sf.
As the answer given is 2388ft^3 then show your pi workings as 3.14 or 3.1459
