125 km are traveled when traveling at a pace of 75 km/h.
The entire travel time to complete 300 km is 1.14 hours, with an average travel speed of 263.15 km/hr.
Given that,
The first 85 kilometers are traveled at a 51 km/hr pace.
A pace of 135 km/hr is used to cover the second 90 km stretch.
75 km/hr is used to cover the remaining distance.
Journey distance is 300 kilometers.
Distance traveled at 75 km/hr is equal to 300 - (85 + 90) = 125 kilometers.
The total time required was 300/261 miles per hour, or 1.14 hours.
The distance traveled divided by the time required equals 300/1.14, or 263.15 kilometers per hour, as the average speed for the whole trip.
Thus, 125 km are traveled when traveling at a pace of 75 km/h.
The entire travel time to complete 300 km is 1.14 hours, with an average travel speed of 263.15 km/hr.

A 20 feet tree casts a shadow that is 32 feet long. What is the distance from the top of the tree to the tip of the shadow?
Answer:
37.7359
Step-by-step explanation:
first you visualize the shape created
if you visualize it... it will look like a right angled triangle
and we are looking for the longest side
remember the pythagoras theorem c^2= a^2 + b^2
in this case we are looking for c
a^2= 20^2
b^2= 32^2
400+ 1024= 1424
therefore c^2= 1424
then you square root 1424
to get 37.7359

The coordinate bridge shows the cost of different numbers of bookmarks how many sense do for bookmarks cost.
Answer:
54 cents
Step-by-step explanation:
The cost of bookmarks relating to the number of bookmarks is given by the graph shown. Therefore:
From the graph, we can determine the relationship between the cost of bookmarks and the number of bookmarks by using two points. The equation of a line passing through points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\[/tex]
From the graph, y represents the cost of bookmarks in cents and x represent the number of bookmarks. we can see that it passes through the point (2, 30) and (7, 90). Hence:
[tex]y-30=\frac{90-30}{7-2}(x-2)\\\\y-30=12(x-2) \\\\y-30=12x-24\\\\y=12x+6[/tex]
The cost of 4 bookmarks (x = 4):
y = 12(4) + 6
y = 54 cents
52.7 × 12= ?

Dan is stocking up on AA and AAA batteries. He bought 10 packages of batteries for a total of 72 batteries. The AA batteries are sold in packages of 6, and the AAA batteries are sold in packages of 8. Write, but do not solve, a system of equations that can be used to find how many packages of each type of battery Dan bought.
Answer:
x + y = 10
6x + 8y = 72
Step-by-step explanation:
Number of packages = 10
Total batteries = 72
For AA:
batteries per package = 6
Let number of packages = x
For AAA:
batteries per package = 8
Let number of packages = y
Number of AA packages + number of AAA packages = 10
Sum of AA + sum of AAA equals 72 batteries
x + y = 10
6x + 8y = 72
Answer:Answer:
x + y = 10
6x + 8y = 72
Step-by-step explanation:
Number of packages = 10
Total batteries = 72
For AA:
batteries per package = 6
Let number of packages = x
For AAA:
batteries per package = 8
Let number of packages = y
Number of AA packages + number of AAA packages = 10
Sum of AA + sum of AAA equals 72 batteries
x + y = 10
6x + 8y = 72

Find the product (x + 4)
Answer:
4x
Step-by-step explanation:
It would be 4x because you have no value given of the variable "X"
therefore, your answer would just be adding the x to the 4 making it 4x

Evaluate 10m + n²/4 when m=5 and n=4
Answer:
16.5
Step-by-step explanation:
Break down the equation:
10*5=50
4 with an exponent of 2= 16
Then you have: 50+16 / 4
You can simplify it to 66/4
Finally, divide 66 by 4 which equals 16.5

Due in 10 minutes please help !! ASAP Erin buys 2 packs of potatoes costing £2 each, 3 packs of carrots for £3 per pack, and 3 turnips costing 90p each.
If she pays with a £20 note, how much change would she get in pounds, £?
Answer:
£7.3
Step-by-step explanation:
2 x £2=£4
3 x £3 = £6
3 x 90 = 270 = £2.7
£4+£6+£2.7= £12.7
20-12.7=7.3
7 pounds and 3
Answer: 4.3
Step-by-step explanation:
2(2)+3(3)+3(.9)=
4+9+2.7=15.7
20-15.7= 4.3
I'm assuming that 100 p is 1 £, if that's not the case this would be wrong

help please!!!!!!!!! Which image is a reflection of the black polygon in quadrant I?
On a coordinate plane, the black polygon is reflected across the y-axis to form the red polygon.
the black polygon in quadrant I
the red polygon in quadrant II
the blue polygon in quadrant III
the green polygon in quadrant IV
Answer:
The red polygon
Step-by-step explanation:
Think of the quadrants:
The "top right" one is quadrant I
The "top left" one is quadrant II
The "bottom left" one is quadrant III
The "bottom right" one is quadrant IV
When it says "reflected across y-axis", think of the y-axis as a "mirror"
Since the black polygon is in quadrant I, think of it looking into the mirror, or y axis. It is reflecting into quadrant II.
The red polygon is in quadrant II.
Sorry! I know this is a really weird explanation, but hope it helps!
Answer: The answer is the red polygon in quadrant ll (B)!

Step-by-step explanation:
Given: A regular hexagon; M is the midpoint of angle NO and RP. Prove: Angle NRM = Angle OPM
Answer:
Step-by-step explanation:
Since it is a regular hexagon, the length of its sides are equal. And same as the distance across its flats.
So that;
NR ≅ OP (property of a regular polygon)
PM ≅ RM (half of the distance across flats of a polygon)
NM ≅ OM (half of the distance across flats of a polygon)
<NMR ≅ <PMO (vertically opposite angles)
<NRM ≅ <OPM (alternate angle property)
<RNM ≅ <POM (alternate angle property)
This therefore proves that: ΔNRM = ΔOPM

Write as a fraction and fractional model model: there is one container of fruit juice and 2 people want juice
Question seems incomplete but we would make assumptions in order to answer and explain
Answer and explanation:
If we wish to model this situation in the form of a fraction: there is one container containing 30 cans of fruit juice and 2 people want fruit juice, we would be finding how many fruit juice each person would get from the container.
Given one container= 30 cans of fruit juice
Number of persons that require fruit juice = 2
Therefore fraction of fruit juice in relation to required fruit juice= 30/2
Kim got to the grocery store at 11:19 in the morning. She spent 24 minutes in the store. Find the points on the number line that show the number of minutes after 11:00 when she got to and left the store.
Answer:
43 minutes
Step-by-step explanation:
Arrival time at grocery store = 11:19 a.m
Time spent in store = 24 minutes
Number of minutes after 11:00 a.m when she arrived and left the store :
Time she left the store :
11:19 a.m + 24 minutes = 11:43 a.m
Minutes after 11:00 when she left :
11:43 - 11:00
= 43 minutes

At which root does the graph of f(x) = (x – 5)2(x + 2)2 touch the x-axis?
-5
0-2
2
05
Answer:
Option B & D
Step-by-step explanation:
Function is;
f(x) = (x - 5)³(x + 2)²
We want to find the point in thich the graph of this function touches the x-axis.
Usually, the point at which the graph touches the x-axis means that y is 0 at that point.
Thus;
(x - 5)³(x + 2)² = 0
This means that;
x - 5 = 0 and x + 2 = 0
Thus,x = -5 and x = -2
