Answer:
w = (0, 15)
Step-by-step explanation:
w²-15w =0
w(w-15)=0
w=0 , w=15
if w=0
0(0-15)=0
0(-15)=0
0=0
if w=15
15(15-15)=0
15(0)=0
0=0

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°

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]

if you cycled for 3 hours and travelled 54 km calculate your average speed
Answer:
162 km per hour
Step-by-step explanation:
Hi!
Speed=Distance x Time
So... 3 x 54 = 162
Hope this helps :)
Answer:
18km/h
Step-by-step explanation:
Well. Speed = Distance x Time
So if she travelled for 3 hours. In that time, she must have travelled 54km.
Average speed is given as kilometres per hour or km/h
So all we need to do is 54/3 which gives us 18km/h
I hope that helps! ^-^

The cost of a pen and a pencil used to be the same, but recently the cost of the pen was increased by ₹4, whereas, the cost of pencil became ₹6 less than 5 times its original value. After the revised cost, if the pen was more expensive than the pencil, what could have been the possible original value of both the products, if the initial price was a natural number?
Answer:
The possible original values of both products are ₹2 or ₹1
Step-by-step explanation:
The question is a word problem leading to simultaneous equations
Let 'x' represent the initial value of the pen and pencil
Therefore;
The final cost of the pen = x + ₹4
The final cost of the pencil = 5·x - ₹6
x + ₹4 > 5·x - ₹6
∴ ₹4 + ₹6 > 5·x - x
₹10 > 4x
₹10/4 > x
₹2.5 > x
Given that x is a natural number, therefore
x ≤ ₹2
The possible original values of both products are ₹2 or ₹1
The possible original value of both products is ₹ 1 and ₹ 2.
The question is a word problem
Let x represent the initial cost of the pen and pencil since they were initially the same price.
When the costs of the pen was increased by ₹4, its new price is x' = x + 4.
Also, the cost of pencil became ₹6 less than 5 times its original value. So, the new price of the pencil is x" = 5x - 6.
After the revised cost, if the pen was more expensive than the pencil, then we have x' > x".
So, x + 4 > 5x - 6
x - 5x > - 4 - 6
-4x > - 10
x < -10/-4
x < 2.5
Since the initial price of the both products was a natural number, the two natural number less than 2.5 are 1 and 2.
So, the possible original value of both products is ₹ 1 and ₹ 2.

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

Step-by-step explanation:
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)
