Answer:
213.042 km
Step-by-step explanation:
We need to convert 213 km 42 m to km.
We know that,
1 km = 1000 m
or
1 m = (1/1000)km
So,
42 m = (42/1000) km
It means,
[tex]213\ km\ 42\ m=213\ km+\dfrac{42}{1000}\ km\\\\=213.042\ km[/tex]
So, the required answer is 213.042 km.
What is the value of 2a3 - a, when a = 4?
The value of the given equation is 124.

So, the value of a is
[tex]= 2a^3 - a\\\\= 2(4)^3 - 4\\\\= 128 - 4[/tex]
= 124
Hence, The value of the given equation is 124.

Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 42m-by-42m square. Val says the area is 1005.48 m^2. Find the area enclosed by the figure. Use 3.14 for pi. What error might Val have made?
Thanks in advance!
I don't have anymore points so please make a good and accurate answer.
Answer:
Area of the enclosed figure = 3148.74 [tex]m^{2}[/tex]
Step-by-step explanation:
Area enclosed by the figure = 2 x area of the semicircle + area of the square
For the semicircle,
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{42}{2}[/tex]
= 21 m
area of a semicircle = [tex]\frac{1}{2}[/tex] x [tex]\pi r^{2}[/tex]
= [tex]\frac{1}{2}[/tex] x 3.14 x [tex](21)^{2}[/tex]
= 692.37 [tex]m^{2}[/tex]
area of a square = length x length
= 42 x 42
= 1764 [tex]m^{2}[/tex]
Thus,
area enclosed by the figure = 2 x 692.37 + 1764
= 3148.74 [tex]m^{2}[/tex]
The total area enclosed bu the figure is 3148.74 [tex]m^{2}[/tex]

How many small cubes are needed to to completely fit in this rectangular prism?
Answer:
it has to be over 100
Step-by-step explanation:
i think this because if the 1 fraction cube is 1/3*1/3*1/3 big and the cube itself is 2 1/3*3 2/3*3 times long you would have to multiply that and the answer you get for the both of them divide them and see what you get

Ms. Wang and her class are selling bags of cookies to raise money for a field trip.
Each bag weighs 140 grams and has 6 cookies.
Each cookie has the same amount of dough that weighs 14 grams.
Each cookie has the same amount of candy
If a bag of candy has 20 grams of Candy, how many bags of candy does the class need to make 18 cookies?
Answer:
9 bags of candy
Step-by-step explanation:
6 cookies at 14 grams each = 84 grams meaning the remaining grams of the 140 have to be the weight of the candy which = 56 grams (140-84). To find out how much candy is in one cookie divide 56 by 6 which = 9.33333. You then divide 20 by 9.3333 which = 2.14 (rounded to nearest 10th). Since you can get just over 2 cookies worth of candy per bag you only need half the number of cookies in bags of candy (9 bags)
What are the coordinates if (-5,-6) is rotated by 180?
25 pts?
Answer:
(5,6)
Step-by-step explanation:
Initial Coordinate rotated 180° is just a sign change new coordinate
coordinate (x, y) rotated 180° is just a sign change (-x, -y)
if (-x, y) rotated 180° is just a sign change (x, -y)
if (x, -y) rotated 180° is just a sign change (-x, y)
if (-x, -y) rotated 180° is just a sign change (x, y)

What is the measure of angle D?
Answer:
m<D = 26
Step-by-step explanation:
<D = x
x + 122 + 32 = 180
x + 154 = 180
x = 180 - 154
x = 26
Answer:
Step-by-step explanation:
<D + 122° + 32° = 180° ( being sum of angles of triangle )
< D = 180° - 154°
< D = 26°

The angle measure of angle LNM is __Degrees
Answer:
90 Degrees
Step-by-step explanation:
<LMN is an interior angle whose measure is equal to one-half the measure of its intercepted arc. Since the intercepted arc LN is the diameter of the circle, its measure is 180 degrees, so m<LMN = 90.

Answer:B
Step-by-step explanation:
help please! find m∠bcf
Answer:
BCF = 140°
See attached image.
Answer:
m<BCF=140°
Step-by-step explanation:
first find m<BCD
m<BCD=180-50-90
m<BCD=40°.
to find m<BCF, we can do 180-m<BCD, since m<BCD and m<BCF add up to 180° (they form a straight angle)
180-m<BCD=m<BCF
180-40=m<BCF
m<BCF=140°
