A car initially moving at 4 m/s accelerates to a new velocity of 10 m/s in a time of 3
seconds. What was the acceleration of the car?

Answers

Step-by-step explanation:

Hey there!

Given;

Initial velocity (u) = 4m/s

Final velocity (v) = 10m/s.

Time(t) = 3s

Acceleration (a) = ?

We know;

[tex]a = \frac{v - u}{t} [/tex]

Keep all values.

[tex]a = \frac{10 - 4}{3} [/tex]

Simplify it.

[tex]a = \frac{6}{3} [/tex]

Therefore, acceleration is 2m/s^2.

Answers

Answer:

Step-by-step explanation:

Given: He needs 8ft and 6 ft

The trim costs 2.95 per foot

so if we do 8 times 2.95 we get 23.60

Next we do the same with 6 and we get 17.7

Add then together and we get $41.30

i need help with multiplying decimals i ust dont get it i also need help with dividing decimals

Answers

Answer:

To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.

To divide a decimal by another decimal: Move the decimal point in the divisor to the right until it is a whole number. Move the decimal point in the dividend to the right by the same number of places as the decimal point was moved to make the divisor a whole number. Then divide the new dividend by the new divisor.

Answer:

Step-by-step explanation:

Okay, first multiplying decimals:

If you want to multiply decimals first you have to put the 2 decimals one on top of each other

for example:

  2.27

x 4.89

Then multiply it just like if you were multiplying a regular number without the decimals

  227

x 489

This equals 111,003 now to figure out the answer we can count that there are 4 numbers after the decimal point so you move the decimal point 4 to the left so the answer would be 11.1003

Two trains leave stations 204 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at miles per hour. How long will it take for the two trains to meet?

Answers

Answer:

t = 1.23 hours

Step-by-step explanation:

Given that,

Distance between two stations is 204 miles

One train travels at 90 miles per hour while the other travels at 75 (let) miles per hour.

We need to find how long will it take for the two trains to meet.

As both cars travel toward each other, it means they approach with a speed of 90 mph + 75 mph = 165 mph.

Let t is the time when they meet. So,

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{204}{165}\\\\t=1.23\ h[/tex]

It will take 1 hour 23 minutes for the trains to meet.

Denver is planting strawberry seedlings in a new garden. He can plant 3 rows of a certain length with 2 seedlings left over or 4 rows of the same length with 3 seedling spots left empty. What is the length, x, of each row in meters?

Answers

Answer:

The length of each row is 5 m.

Step-by-step explanation:

It is given that,

Denver can plant 3 rows of a certain length with 2 seedlings left over and 4 rows of the same length with 3 seedling spots left empty.

Let the length of each row is x.

Case 1,

Total number of seeds = 3x+2

Case 2,

Total number of seeds = 4x-3

From both of the cases,

3x+2 = 4x-3

Taking like terms together,

3x-4x=-3-2

-x=-5

x=5

So, the length of each row is 5 m.

If you are trying to decide whether a system of equations has a solution, would you rather have the equations or the graphs? Why?

Answers

Graphs because it makes it easier

When determining if the set of equations has a solution, this is when graphing is the best method to be used.

What are linear equations in two variables?

If an equation is written in the form axe + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables.

When there is a system of equations, there are mainly three solutions for equations that are,

no solution, unique solution, and infinitely many solutions,

these solutions can be found by solving the equations or comparing their variables, hence the process takes more time,

but the same process for finding the solutions can be done by graphing method and it is easy as compared to the above method because,

As it offers the visual to record what they have actually looked for, it was seen to be the greatest way at the time it was taught to new students for solving the system of two equations in two variables.

Hence graph method is best to find the solution to equations.

Answer:

13. x = 21; y = 15

14. x = 8; y = 11

15. x = 16; y = 23

Step-by-step explanation:

13. (3x - 16)° + (6x + 7)° = 180° (same side interior angles are supplementary)

Solve for x

3x - 16 + 6x + 7 = 180

Collect like terms

9x - 9 = 180

Add 9 to both sides

9x = 180 + 9

9x = 189

Divide both sides by 9

x = 189/9

x = 21

(6x + 7)° = (11y - 32)° (vertical angles are congruent)

Solve for y by substituting x = 21 into the equation

6(21) + 7 = 11y - 32.

126 + 7 = 11y - 32

133 = 11y - 32

Add 32 to both sides

133 + 32 = 11y

165 = 11y

Divide both sides by 11

165/11 = y

15 = y

y = 15

14. (11x - 25)° = (8x - 1)° (alternate exterior angles theorem and corresponding angles theorem)

Solve for x

11x - 25 = 8x - 1

Collect like terms

11x - 8x = 25 - 1

3x = 24

Divide both sides by 3

x = 24/3

x = 8

(8x - 1)° + (15y - 48)° = 180° (linear pair theorem)

Substitute x = 8 into the equation and solve for y

8(8) - 1 + 15y - 48 = 180

64 - 1 + 15y - 48 = 180

15 + 15y = 180

Subtract 15 from both sides

15y = 180 - 15

15y = 165

Divide both sides by 15

y = 165/15

y = 11

15. (7x - 44)° = (4x + 4)° (alternate exterior angles theorem)

Solve for x

7x - 44 = 4x + 4

Collect like terms

7x - 4x = 44 + 4

3x = 48

Divide both sides by 3

x = 48/3

x = 16

39° + (8y - 43)° = 180° (corresponding angles theorem and linear pair theorem)

Solve for y

39 + 8y - 43 = 180

Collect like terms

-4 + 8y = 180

Add 4 to both sides

8y = 180 + 4

8y = 184

Divide both sides by 8

y = 184/8

y = 23

We will be reading the Monkey's Paw tomorrow, one of the first three-wishes-gone-bad stories every written. I'd like you to start your own three-wishes story in your writing journals today. (Journal #10) Start in today's writing piece by figuring out how you get the wishes. Put a modern twist on it. Examples: do you wake up to your cell phone buzzing announcing you have three wishes,? do you open your locker at school, and they fall out?

Be creative I look around the market trying to see what I should buy when I come around a table with magic Items. Now Im 16 I know that magic isnt real, but I couldnt help myself. I felt drawn to one particular object or paw I should say. I could see the merchant looking at me to the monkey's paw. I felt ridiculous asking this but I wanted to know: What does this do? As in like magic? Ah this is a rare artifact only known as the wisher curse. Everyone who has ever owned it- he stops. Everyone who has ever owned it will get 3 happy wishes, and live happily ever after. he smiled. So there is a genie in there? I asked. No, there is not, but I will give it to you for 50 euros if you want. I thought about it, and 50 euros for a monkey's paw? I wanted to say no, but then the merchant lowered the price to 15 euros. I agreed and he gave me a bag for the monkey's paw and I paid him some of my work money. Not exactly how I thought I would spend my money, I thought. Before I left the merchant whispered something to his employee: She doesnt even know half of it. but before I could ask what that meant my phone rang and my mom was calling, probably to ask where in the world am I. When I got home the first thing I did was go directly to my room and lock my door. I slid down to my soft carpet and opened my bag to where the monkey's paw layed. I grabbed it and held it into my hands and examined it very closely. Before I could even make a wish my mom banged on my door. Ayn! Unlock your door! I sighed and wished she would just leave me alone for once. I unlocked the door and expected her to be there in her pajamas and have a look that could kill anyone. I opened the door but she was nowhere to be found. Mom! I yelled. No answer. I left my room and looked at our apartment. I looked in her room, no one. I looked in the bathroom, the kitchen, the closet, the tiny hallway, she wasnt there! She was just there, I thought! I gasped the monkey's paw! I still had it in my hand without realizing. I thought back to what could have made my mom disappear. It's not like I said I wished for her to disappear I only said just to leave me alone. Wait another word for leave is to disappear! I just poofed my mom! I wish my mom was still here! I said. Nothing. Sweetie Im home! Mom! I sighed with relief. I gave her a hug. I looked at her and that wasnt my mom! Who are you!
