Out of a journey of 300km;the firt part of ditance 85km i covered at a peed of 51km/h, the econd part of 90km at a peed of 135km/h and the remaining ditance at a peed of 75km/h. Find:
(1) the ditance covered at a peed of 75km/h. (2) the total time taken. (3) the average peed for the whole journey

Answers

Answer 1

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.

Write as a fraction and fractional model model: there is one container of fruit juice and 2 people want juice

Answers

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

The coordinate bridge shows the cost of different numbers of bookmarks how many sense do for bookmarks cost.

Answers

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

Given: A regular hexagon; M is the midpoint of angle NO and RP. Prove: Angle NRM = Angle OPM

Answers

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

At which root does the graph of f(x) = (x – 5)2(x + 2)2 touch the x-axis?
-5
0-2
2
05

Answers

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

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.

Answers

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

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

Answers

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.
