Answer:

There are two equivalent formulas to choose from when solving work-rate problems. If two people are working together on a job then their work rates add and they can perform the job working together in a shorter amount of time. If we let x = the time it takes a person to complete a task then his work rate is 1/x. In other words, he can complete the 1 job in x number of hours. If we let y = the time it takes a second person to complete the task and t = the time it takes for both people working together we get the following work-rate formulas:

Answer:

$60, because if $10 is half, then before lunch Hunter had $20.

If Hunter used 2/3 of his money to buy that video game, and remained with $20 that means that 1/3 of the original amount of money he had was $20.

$20 * 3 = $60. Hunter began with $60.

Given:

16 emails to 6 text messages- 10 emails to 4 text messages

To find:

Whether 16 emails to 6 text messages- 10 emails to 4 text messages proportional or not.

Solution:

Check the ratio of emails to text. If the ratios are equal then the relation is proportional.

16 emails to 6 text messages.

[tex]\dfrac{Emails}{Text}=\dfrac{16}{6}[/tex]

[tex]\dfrac{Emails}{Text}=\dfrac{8}{3}[/tex]

[tex]\dfrac{Emails}{Text}=8:3[/tex]

10 emails to 4 text messages.

[tex]\dfrac{Emails}{Text}=\dfrac{10}{4}[/tex]

[tex]\dfrac{Emails}{Text}=\dfrac{5}{2}[/tex]

[tex]\dfrac{Emails}{Text}=5:2[/tex]

Since [tex]\dfrac{8}{3}\neq \dfrac{5}{2}[/tex] or [tex]8:3\neq 5:2[/tex], therefore, it is not proportional.

Answer: y-1=-1/2(x-5)

Step-by-step explanation:

[tex]\frac{2-1}{3-5}[/tex]

-1/2 slope

y-[tex]y_{1}[/tex]=m([tex]x-x_{1}[/tex])

y-1=-1/2(x-5)

y-1=-1/2x +5/2

y=-1/2x+7/2

Hi there!

So we know that the two train together is a total of 192 tons and the difference of their weights is 120 tons...

Ok let think...

When we’re looking at the once place, you’ll see a two... this means that the two train both have a ending of 1 since 2 is split into 1...

That would be another clue..

Now let think again...

If it would be 151 and we subtract by 120.. we would get...

[tex]151-120=31[/tex]

Well it ends with a 1 so it would be perfect but we have to see if 151 and 31 together adds up with the total of 192..

[tex]151+31=192[/tex]

This means that train A could be 151 tons or 31 tons and train B can also be wither 151 tons or 31 tons...

Answer:

by Pythagoras theorm

H² = B² + P²

H². = 40² + 42²

= 1600 + 1764

= 3364

= 58²

H = 58

Step-by-step explanation:

Answer:y=Mx+b

Step-by-step explanation:

Answer:

Step-by-step explanation:

(3,2),(-9,6)

slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3

y = mx + b

slope(m) = -1/3

use either of ur points...(3,2)....x = 3 and y = 2

now we sub into the formula and find b, the y int

2 = -1/3(3) + b

2 = -1 + b

2 + 1 = b

3 = b

so ur equation is : y = -1/3x + 3 <==

Answer:

C~7

Step-by-step explanation:

The value of x is 7 if the equation can be reduced to (x + 9)³ = 4096 after applying the properties of the integer exponent option (C) 7 is correct.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The equation is:

[tex]\rm 3(x + 9)^{3/4} = 24[/tex]

After solving:

[tex]\rm (x + 9)^{3/4} = 8[/tex]

(x + 9)³ = 4096

x + 9 = ∛4096

x + 9 = 16

x = 7

Thus, the value of x is 7 if the equation can be reduced to (x + 9)³ = 4096 after applying the properties of the integer exponent option (C) 7 is correct.

Answer:

6.3 in.^2

Step-by-step explanation:

The diameter of the circle is 4 in., so the radius of the circle is 2 in.

[tex] A_{sector} = \dfrac{n}{360^\circ} \pi r^2 [/tex]

The two central angles have a total measure of 60 deg + 110 deg = 170 deg.

The central angle of the shaded sector is 360 deg - 170 deg =  190 deg.

We will use n = 190 deg in the area formula.

[tex] A_{sector} = \dfrac{190^\circ}{360^\circ} \pi (2~in.)^2 [/tex]

[tex] A_{sector} = 6.3~in.^2 [/tex]

Answer:

24.2

Step-by-step explanation:

There is but one answer to this. It appears below.

Let's try it out and see what happens. We'll do it the way it sits.

Sin 40/8 = sin(x) / 7             Multiply both sides by 7

7* Sin(40) / 8 = sin(x)

Sin(40) = 0.6428

7 * 0.6428 / 8 = sin(x)

.56245 = sin(x)

x = sin-1(0.56245)

x = 34.23

Rounded to the nearest tenth, it is 24.2
