The shortest route from London to Cambridge is 60 miles. A lorry is expected to take 1.5 hours to travel this route. The lorry actually travels by a different route which increases the distance by 20%, but it still arrives in 1.5 hours. By how many more mph than the expected speed does the lorry travel?
Answers
Answer:
8 mph
Step-by-step explanation:
The lorry's shortest route:
60 miles in 1.5 hours
speed = distance/time = (60 miles)/(1.5 hours) = 40 mph
The longer route:
time = 1.5 hours
distance = 20% more than 60 miles = 1.2 * 60 miles = 72 miles
speed = distance/time = (72 miles)/(1.5 hours) = 48 mph
Difference in speeds: 48 mph - 40 mph = 8 mph

the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?
Answers
Explanation
The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.
(angle ABD) + (angle DBC) = 180
(134) + (2x) = 180
2x = 180-134
2x = 46
x = 46/2
x = 23
Answer: x=23 and the angle relation used was supplementary angles
Step-by-step explanation:
first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Tatyana is planting 20 flowers and 6 bushes in rows. If she wants all the rows to be exactly the same, with no plants left over, what is the greatest number of rows Tatyana can plant?
Answers
Answer:
she can plant 3 rows
Step-by-step explanation:
6×3=18 if you want an equal amount do 18, if you want to plant them all its four rows
Answer:
Tatyana can plant 2 rows of plants for the rows to be the same without left over plants.
Step-by-step explanation:
So you need to know the greatest number that you can plant for flowers and bushes, the bushes you can do 6 but the flowers cant be divided into 6, so now you look at the next number, well its 3 right? yeah, but again, 20 cant be divided into three groups. The next number is 2, and 20 can be divided into 2, so the answer is 2.

Arthur sits park reading a newspaper, then starts walking home at a constant pace he stops for bagels then walks the rest of the way home
1.what does the x-axis represent in this situation?
2. What’s does the y-axis represent?
Answers
Answer:
1. What does the x-axis represent in this situation?
The x-axis represents time.
2. What does the y-axis represent?
The y-axis represents distance.
3. During which parts of the graph does Arthur's distance from home decrease?
Sections 2 and 4.
4. When is Arthur waiting for bagels? Explain how you know.
Section 3. The flat areas represent times when Arthur is not moving. We know that the first flat area shows Arthur reading his newspaper, and the third is when he reaches home; so the second flat area represents the time in which Arthur is waiting for bagels.
5. If Arthur's pace had not been constant after leaving the bagel shop, which part of the graph
would change? Explain how that part of the graph would change.
The part of the graph that would change is part 4. If his pace was not constant, section 4 would not be uniform, and would have many abnormalities. Essentially, Arthur would be randomly speeding up and slowing down.
6. If Arthur had spent less time reading his newspaper, which part of the graph would change? How would that part change?
If Arthur had spent less time reading his newspaper, the whole graph would change. Section one would be shorter, and the entire line would also be shorter. The distance on the graph from the beginning of section 1 to the end of section 5 would be reduced.
Find the surface area of the cube
Answers
Answer:
150cm²
Step-by-step explanation:
cube has 6 sides of equal area.
each side is a square.
area of square = length X width (or length X height, width X height).
area of one side = 5 X 5 = 25cm².
6 sides, so total surface area = 6 X 25 = 150cm²
Answer:
of the entire cube: 150
Step-by-step explanation:
how you find the surface area of a cube is to find the area of just one side then timesing it by 6. so one square is 5 by 5. five times five is 25. then 25 times 6 is 150.

If cos x=−6/7, and 90°
Answers
Answer: 0.4693877
Step-by-step explanation:
Given that:
cos x=−6/7,
From trigonometry :
Cosx + sinx = 1
Cos2x = cos(x + x)
Recall the double angle identity:
Cos2x = 2cos^2x - 1
Sin2x = 1 - 2sin^2x
Since cosx = - 6/7
Then
Cos2x = 2cos^2x - 1
Cos2x = 2cosx^2 - 1
Cos2x = 2(-6/7)^2 - 1
Cos2x = 2(36/49) - 1
Cos2x = 2 * (72/98) - 1
Cos2x = (2 * 0.7346938) - 1
Cos 2x = ( 1.4693877 - 1)
Cos2x = 0.4693877
