An object is moving east, and it’s velocity changes from 65 m/s to 25 m/s in 10 seconds.which describes acceleration

Answers

Answer 1

Answer:

The acceleration of object is -4 ms⁻²

Step-by-step explanation:

We are given:

Initial Velocity = 65 m/s

Final Velocity = 25 m/s

Time t = 10 seconds

We need to find acceleration.

The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]

Putting value in the formula and finding acceleration:

[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]

So, acceleration of object is -4 ms⁻²

The two prisms below are similar. What is the value of x?
24
4
16
A. 4
B. 24
C. 16
D. 1

Answers

Answer:

A

Step-by-step explanation:

Since the prisms are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{16}{4}[/tex] = [tex]\frac{x}{1}[/tex] ( cross- multiply )

4x = 16 ( divide both sides by 4 )

x = 4 → A

The value of x on the prism is 4.

What are Similar Figures?

Similar figures are those figures which are having the same shape, but the sizes are different.

Given are two prisms.

We have to find the length of x.

Given that they are similar.

So the ratio between their dimensions is equal.

So,

x / 1 = 16 / 4

x = 4

Hence the value of x is 4.

i would really appreciate if someone could explain the process to solve it

Answers

Answer:

x = 12°

Detailed explanation down below.

Step-by-step explanation:

Ill be delighted to help

8° + 6x is an exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

In this situation, those two angles are 30° and 4x+2°

So lets put this in an equation

30° + 4x + 2° = 8° + 6x

4x + 32° = 6x + °8

Now lets subtract 8° from both sides to make it simpler

New equation =

4x + 24° = 6x

Lets evaluate X=

6x - 4x = 24°

2x = 24°

x= 24/2

x= 12°

One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 468 ​, find the numbers

Answers

Answer:

Step-by-step explanation:

Givens

Let the first number = x

Let the second number = 2x

Let the third number = x + 100

Total = 468

==============

Solution

x + 2x + x + 100 = 468                    Combine the xs

4x + 100 = 468                                Subtract 100 from  both sides

4x = 468 - 100

4x = 368                                          Divide by 4

x = 368/4

x = 92

===============

Answer

First number =                     92

Second num = 2 * 92=       184

Third number = 92 + 100= 192

Total                                    468

Q: Find Jeff's total earnings if his sales are$948.

Answers

Answer:

His total earnings for sales of $948 is $425.84

Step-by-step explanation:

Let the percentage of his commission be a percentage with its value represented as x and b be his base salary , y as his total earnings

So we have;

y = x% of sales + base salary

for 849 sales and 417.92 , we have

417.92 = 8.49x + b •••••••(i)

for 1011 sales and 430.88 servings

430.88 = 10.11x + b ••••••(ii)

Subtract i from ii

12.96 = 1.62x

x = 12.96/1.62

x = 8

To get b, we substitute

430.88 = 10.11(8) + b

b = 430.88 - 10.11(8) = 350

Commission is 8% , base earnings is $350

So for total sales of 948;

y = 8% of 948 + 350

y = $425.84
