a bicyclist traveling at an average speed of 18 km/h takes 3 hours and 30 minutes to complete his journey. How many hours less will he take if he bicycles at a speed which is 3 km/h faster
Answers
Answer:
It will take him 0.5 (30 minutes) less hours if he bicycles at a speed that is 3km/h faster.
Step-by-step explanation:
18 km/h x 210 minutes = 3,780
3,780/21km = 180 minutes = 3 hours
If we multiply the speed by the time we can find the distance, using that we can find the time it takes to travel the same distance with more speed (21km/s this time).
Therefore, it will take 30 minutes less if he travels 2 km/s faster or 0.5 less hours

Answer:
Answer B
Step-by-step explanation:
You need to first find the surface area of the triangular prism.
In order to do that, we need to first know the length of the base of the triangles on both side. So, I used the pythagorean theorem (a²+b²=c²) after making the triangle a right triangle by cutting it in HALF.
a²+b²=c²
a²+2.6²=3²
a²+6.76=9
Subtract 6.76 on both sides
a²=2.24
a=√2.24
a=1.49666295471
Now, we know that the base of HALF of the triangles on both sides of the prism is 1.496......
We need to MULTIPLY this by 2 to get the full length. So, the length of the bases of both triangles is 2.99332590942
The height of the triangles is 2.6
We are going to first find the area of one triangle and multiply it by 2, to get the area of both triangles.
Area of a triangle = base x height ÷ 2
2.6 x 2.99332590942= 7.78264736449
7.78264736449 ÷ 2 = 3.89132368224
3.89132368224 x 2 (because we have 2 triangles) =7.78264736449 cm squared
Now, we know the area of both triangles, but we now need to add the add the surface area of the rectangles in the net.
Area of a rectangle = length x width
We know that all of the three rectangles are equal in size, and that the length of each one of them is 15 cm. However, the width/height of each one is unknown. We will find out the height of each one by looking at the length of the base of the triangle attached to the first one. We know that because of the base of the triangles = 2.99332590942, the width of the attached rectangles are 2.99332590942. We found this using the Pythagorean theroem (look above).
15 x 2.99332590942= 44.8998886413
44.8998886413 x 3 (because we have 3 of the same rectangles)= 134.699665924 cm squared
Now, we must ADD the surface area of the rectangles AND the triangles.
7.78264736449 (triangles) + 134.699665924 (the three rectangles)= 142.482313288 cm squared.
The CLOSEST OPTION to the answer we got is ANSWER B because it is 142.8 cm squared, which is the closest to the answer we got which was 142.482313288 cm squared.

Container A was filled with water to the brim. Then, some of the water was poured into an empty Container B until the height of the water in both containers was the same. Find the new height in both water containers
Answers
The new height of the water container is equal to 66.7 centimeters.
For Container A:
Height = 40 cm.Length = 25 cm.Width = 30 cm.For Container B:
Length = 18 cm.Width = 25 cm.First of all, we would determine the volume of the water in Container A:
The volume of a rectangular prism.Mathematically, the volume of a rectangular prism is given by this formula:
[tex]V = L \times W \times H[/tex]
Where:
V is the volume.L is the length.W is the width.H is the height.Substituting the given parameters into the formula, we have;
[tex]V = 25 \times 30 \times 40[/tex]
V = 30,000 cubic centimeters.
Note: The volume of the two containers must be the same.
The new height:
[tex]30000=18\times 25 \times h\\\\30000=450h\\\\h=\frac{30000}{450}[/tex]
h = 66.7 centimeters.

Matt had $125 but needs to buy no-slip shoes for work. Meaning u have to subtract $50 from $125. Getting u $75
And Amy has $230 and has to buy clippers which is $30. So just like Matt subtract $30 from $230 and ur left with $200

If y - 2x = 3 and y - x = 1, what are the values of x and y?
Answers
Answer:
x = -2
y = -1
Step-by-step explanation:
y - 2x = 3 and y - x = 1
Subtract the second equation from the first
y - 2x = 3
- ( y - x = 1)
––––––––––
-x = 2
Multiply both sides by -1
x = -2
Sustitute x = -2 into the first equation
y - 2(-2) = 3
y + 4 = 3
Subtract 4 from both sides
y = -1

Answer:
-2.9°F
Step-by-step explanation:
First subtract the temperature from Tuesday to Monday because it is getting colder, and you get 6.6 (-5.4 - 1.2 = -6.6)
Then add 3.7 because it is getting warmer and you get
-6.6 + 3.7 = -2.9

One pound costs 1.26, two costs 1.47, three costs 1.68, and four costs 1.89. So we calculate how much it increases in each pound.
1.26 + 21 = 1.47
1.47 + 21 = 1.68
1.68 + 21 = 1.89
1.89 + 21 = 2.10
2.10 + 21 = 2.31
2.31 + 21 = 2.52
2.52 + 21 = 2.73
8 pounds cost: 2.73
