Ра:
Calculate the time it takes for the car travel this distance,
Give your answer in seconds​

Answers

Answer 1

Answer:

The answer is 20 hours

Step-by-step explanation:

This is becuase 1280 divided by 64 equals 20.  There are no unit coversions.

Answer 2

In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

Given that,
A car travels a distance of 1280 meters at an average speed of 64 kilometers per hour.

What is speed?

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
Time  = distance/speed
Time. t = 1.280 / 64

t = 0.02 hours

Thus, In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

Question Says:-

An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?

Answer:-

See, let us consider the sides as l as per question.

And, perimeter as p as per question.

We know that:-

The sum of all the boundary gives us the perimeter of the figure.

It is Equilateral Triangle, so the equation will be:-

[tex]l + l + l = p[/tex]

Now, adding it up, we get

[tex]3l = p[/tex]

So, 3l=p relates the side and perimeter.

Find the slope of the line through the given points. (1,3) and (0,−9)

Thank you so much :)

Answers

Answer:

The answer is 12

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(1,3) and (0,−9)

The slope is

[tex]m = \frac{ - 9 - 3}{0 - 1} = \frac{ - 12}{ - 1} = 12 \\ [/tex]

The roots of a quadratic equation are 7 and -3. Which quadratic equation has these roots?
(x + 7) (x – 3) = 0

(x - 7) (x + 3) = 0

(x – 7) (x – 3) = 0

(x + 7) (x + 3) = 0

Answers

The answer is (x - 7) (x + 3) = 0

Explanation: Put both equations equal to 0, so it looks like this: (x - 7) = 0 (x + 3) = 0
It doesn’t matter what you do first but I’ll start with (x - 7) = 0
First you remove the parenthesis
x - 7 = 0
Next you add the 7 on both sides. You do this to cancel the 7 so that the x is by itself.
x = 7
It’s the same thing for the (x + 3) = 0 but I’ll show you anyways
Remove parentheses
x + 3 = 0
Subtract the 3 from both sides that way the 3 cancels out and the x is on its own
x = -3

b) s > 94, Emmerson must earn above a 94 on his final test to earn an "A" in his class.

d) s 294, Emmerson must earn at least a 94 on his final test to earn an "A" in his class.

Answers

Answer:

D) Emerson must earn at least a 94 on his final test to earn an “A” in his class

Step-by-step explanation:

We calculate this using mean in this format:

Test Scores / # of Test ≥ 90 (which is an A)

Substitute:

(92 + 86 + 88)+ x / 4 ≥ 90

Add:

266 + x / 4 ≥ 90

Get Rid of the Denominator:

(4) 266 + x / 4 ≥ 90 (4)

Multiply:

266 + x ≥ 360

Isolate x (Subtract 266 From Both Sides):

x ≥ 94

This means that x (His final test score) has to be greater than (above) or equal to 94. A term for greater than or equal to is “at least.” Hope this helps :)

The Story of Native American CornEdward Eggleston1 When the Pilgrims came to Cape Cod, they sent out Miles Standish and some other men to look through the country and find a good place for them to settle. Standish tried to find some of the Native Americans in order to make friends with them, but the Native Americans ran away whenever they saw him coming. One day he found a heap of sand. He knew it had been lately piled up, because he could see the marks of hands on the sand where the Native Americans had patted it down. Standish and his men dug up this heap. They soon came to a little old basket full of Native American corn. When they had dug further, they found a very large new basket full of fine corn, which had been lately gathered.2 The Europeans, who had never seen it before, thought Native American corn was very beautiful. Some of the ears were yellow, some were red. On other ears blue and yellow grains were mixed. Standish and his men said it was a "very goodly sight."3 They wanted the corn for seed. They made up their mind to pay the Native Americans whenever they could find them. The next summer they found out who were the owners of this buried corn, and paid them for all the corn they had taken. If they had not found this corn, they would not have had any to plant the next spring, and so they would have starved to death.4 The people that were with Miles Standish settled at Plymouth. They were the first that came to live in New England. A Native American named Squanto came to live with the white people at Plymouth. Squanto was born at this very place. He had been carried away to England by a sea captain. Then he had been brought back by another captain to his own country. When he got back to Plymouth, he found that all the people of his village had died from a great sickness. As he could speak some English, and as all his own tribe were dead, he now came to live with the white peopleChoose the sentence that BEST summarizes the story.A) The Indians and Miles Standish were friends.
