What is the value of 15 + x2 when the value of x is 3? also there's a tiny 2 above the 15

Answers

Answer 1

Answer:

231

Step-by-step explanation:

So the tiny 2 above the 15 means 15 is squared

15 squared = 225

225 + x(2)

If x = 3, then simply plug that into the equation

225 + 3(2)

225 + 6

231 is your answer

Answer 2

Answer:

231

Step-by-step explanation:

I put the equation as 15^2+2(3) I'm guessing the x was suppose to be after the 2 because it doesn't make sense putting x in front of the two....

Which of the following statements about JK and JL is true?


A. JK is longer than JL
B. JK and JL are the same length
C. JL is longer than JK
JK IS 9 units long

Answers

Answer:

jk is longer than jl

Step-by-step explanation:

The distance between J and L is more than J and K hence, the correct option will be (A).

How to find the distance between any two points?

To find the distance between any two points first assign any one point by (1) whose coordinates will be (x₁, y₁) and assign the remaining point with (2) whose coordinates will be (x₂,y₂).

Now, use the below formula to find out the distance

[tex]\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}[/tex]

Let's assign J by (1) whose coordinate (2,4) work like (x₁,y₁) and assign L by (2) whose coordinate (1,-1) work like (x₂,y₂).

Now by the distance formula, the distance JL is

⇒  [tex]\sqrt{(1-2)^2 +(-1-4)^2}[/tex]

⇒   [tex]\sqrt{(-1)^2+(-5)^2}[/tex]

⇒    [tex]\sqrt{26[/tex] = 2.236

Now again assign J by (1) whose coordinate (2,4) work like (x₁,y₁) and assign K by (2) whose coordinate (7,-8) work like (x₂,y₂).

Now by the distance formula, the distance JK is

⇒   [tex]\sqrt{(7-2)^2 +(8-4)^2}[/tex]

⇒   [tex]\sqrt{(5)^2 +(4)^2}[/tex]

⇒[tex]\sqrt{(41)}[/tex] = 6.403

Hence, it's clear that the JK is longer than JL.

Step-by-step explanation:

The two ordered pairs are (0.05, 0.1) and (0.1, 0.2).

The graph is shown below.

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y = 4x

y = number of miles

x = number of hours

4 miles per hour.

Now,

The rate is 2 miles per hour.

This means,

y = 2x

Now,

x = 3 minutes = 3/60 hour = 1/20 hour = 0.05 hour

y = 2 x 1/20 = 1/10 miles = 0.1 miles

The ordered pair is (0.05, 0.1)

x = 6 minutes = 6/60 hour = 1/10 hour = 0.1 hour

y = 2 x 1/10 = 1/5 miles = 0.2 miles

The ordered pair is (0.1, 0.2)

Thus,

The ordered pairs are (0.05, 0.1) and (0.1, 0.2).

Roscoe hit a ball straight up at a speed of 96 ft/s. His bat hit the ball at a height 3 ft above the ground. After how many seconds did the ball hit the ground? (Give your answer to the nearest hundredth of a second.)

Answers

Answer:

t = 6.031 seconds

Step-by-step explanation:

Roscoe hit a ball straight up at a speed of 96 ft/s.

His bat hit the ball at a height 3 ft above the ground.

We need to find how many seconds did the ball hit the ground.

Using equation of motion to find height of the ball.

[tex]h=-16t^2+96t+3[/tex]

When it hits the ground.

h = 0

[tex]-16t^2+96t+3=0[/tex]

It is a quadrctic equation where a = -16, b = 96 and c = 3

[tex]t=\dfrac{-96\pm \sqrt{96^2-4(-16)(3)} }{2(-16)}\\\\t=-0.031\ s, 6.031\ s[/tex]

Neglecting negative value.

So, after 6.031 seconds the ball will hit the ground.

Given :

Roscoe hit a ball straight up at a speed of 96 ft/s.

His bat hit the ball at a height 3 ft above the ground.

To Find :

After how many seconds did the ball hit the ground.

Solution :

When the ball reaches the same height from which it is thrown ( i.e. 3 ft ) its displacement will be zero.

So, using equation of motion :

[tex]s = ut + \dfrac{at^2}{2}\\\\96t - \dfrac{10t^2}{2} = 0\\\\5t^2 - 96t = 0\\\\t( 5t - 96 ) = 0\\\\t = \dfrac{96}{5}\\\\t = 19.2 \ s[/tex]

Now, time taken to reach ground from 3 feet of height is :

[tex]s = ut + \dfrac{at^2}{2}\\\\3 = 96t + 5t^2 \\\\5t^2 + 96t - 3 = 0[/tex]

t = 0.03 s

Therefore, time taken is T = 19.2 + 0.03  = 19.23 seconds.

Joshua is writing a novel. He wrote the same number of pages each day for a 8 days. At the end of 8 days he had 136 pages complete. Write an equation relating x, the number of days, to y, the total pages.

Answers

Answer:

8x = 136

Where: x = 17

Step-by-step explanation:

Joshua is writing a novel. He wrote the same number of pages each day for a 8 days. At the end of 8 days he had 136 pages complete. Write an equation relating x, the number of days, to y, the total pages.

Let the number of pages read per day = x

Hence, the number of pages after 8 days = 8 × x = 8x

Total number of pages = y= 136

Therefore:an equation relating x, the number of days, to y, the total pages.

= 136 = 8x

Solving for x

136/8 = x

x = 17

Answers

Given:

The expression is

[tex]2x-5y+3[/tex]

To find:

The equivalent expressions.

Solution:

We have,

[tex]2x-5y+3[/tex]

In option 1,

[tex]x+x-y+1+1+1-y-y-y-y[/tex]

[tex]=(x+x)+(-y-y-y-y-y)+(1+1+1)[/tex]

[tex]=2x-5y+3[/tex]

So, the expression in option 1 is equivalent to the given expression.

Similarly,

In option 2,

[tex]-2+2x+3+(-2y)-y[/tex]

[tex]=2x-3y+1\neq 2x-5y+3[/tex]

So, the expression in option 2 is not equivalent to the given expression.

In option 3,

[tex]-5y-x-x+2+1[/tex]

[tex]=-2x-5y+3\neq 2x-5y+3[/tex]

So, the expression in option 3 is not equivalent to the given expression.

In option 4,

[tex]y+y+y+y+y-2x-1-1-1[/tex]

[tex]=-2x+5y-3\neq 2x-5y+3[/tex]

So, the expression in option 4 is not equivalent to the given expression.

In option 5,

[tex]2+1+x-y+x-2y[/tex]

[tex]2x-3y+3\neq 2x-5y+3[/tex]

So, the expression in option 5 is not equivalent to the given expression.

In option 6,

[tex]x-y+x+1-y-3y+2[/tex]

[tex]=2x-5y+3[/tex]

So, the expression in option 6 is equivalent to the given expression.

Therefore, the correct options are 1 and 6.

Maddie can not decide which of two Ski sets to buy. The original price of each is $850. The first ski set is marked 50% off. The second was marked down by 30% then a few days later an additional 20% off. 1. Find the sale price of the first ski set... 50% off. Show your work. 2. Find the Sale Price of the Second Ski Set Marked 30% then 20%. Show your work. 3. Which one is a better deal for Maddie and why?

Answers

Answer:

$425i. $595             ii. $476First ski

Step-by-step explanation:

1. The first ski was valued at $850 but was then given a 50% discount. The sales price will therefore be:

= 850 * ( 1 - 50%)

= 850 * 50%

= $425

2. The first one was first discounted by 30% so the sales price was:

= 850 * ( 1 - 30%)

= 850 * 70%

= $595

It was then marked down by a further 20%:

= 595 * ( 1 + 20%)

= $476

3. The first ski is a better option because the discount makes it cheaper than the second ski even after the second ski had been discounted twice.

Which expression uses the greatest common factor and the distributive property to rewrite the sum 64 + 32? 16(4+2) ​ 8(8+4) 32(2)+1 ​ 32(2+1) ​

Answers

Step-by-step explanation:

Since 64 = 32 * 2 and 32 = 32 * 1,

64 + 32 = 32(2 + 1).

16(4 + 2) is wrong as 4 and 2 have a GCF of 2.

8(8 + 4) is wrong as 8 and 4 have a GCF of 4.

32(2) + 1 is the wrong application of the distributive property.

Rajesh and his brother Mohib are each mailing a birthday gift to a friend. Rajesh package weighs three more pounds than twice the weight of mohib's package The combined weight of both packages is 15 pounds

Answers

Answer:

Weight of Mohib package = 4 pounds

Weight of Rajesh package = 11 pounds

Step-by-step explanation:

Let

Weight of Mohib package = x

Weight of Rajesh package = 2x + 3

Total weight = 15

Total weight = Weight of Mohib package + Weight of Rajesh package

15 = x + (2x + 3)

15 = x + 2x + 3

15 - 3 = x + 2x

12 = 3x

x = 12/3

x = 4 pounds

Weight of Mohib package = x

= 4 pounds

Weight of Rajesh package = 2x + 3

= 2(4) + 3

= 8 + 3

= 11 pounds
