answer asap, Ill give brainliest, show work

Steve can paint a room three times as fast as Billy. When they work together, Steve and Billy can paint a large room in 4 hours. How many hours would it take Billy to paint it by himself?

Answers

Answer 1
Hey there! :D

If Steve does 3 times the work, we can conclude that he did 3/4 of the job. Billy did 1/4 of the job in 4 hours. We only painted 1/4 of the room in 4 hours. 

That means it would take him 16 hours to complete one room. 4*4= 16. 

It would take him 16 hours to paint a large room by himself. 

I hope this helps!

What is the value of x? Enter your answer in the box. x = . Triangle G E H with segment E D such that D is on segment G H, between G and H. Angle G E D is congruent to angle D E H. E G equals 99.2 feet, G D equals 62 feet, D H equals left parenthesis x plus 2 right parenthesis feet, and E H equals 112 feet.

Answers

Corresponding sides on either side of ED are proprotional, so
.. (x+2)/112 = 62/99.2
.. x +2 = 112*62/99.2 = 70

x = 68 . . . . feet

Answer:

The value of x is 68 ft.

Step-by-step explanation:

Given information: [tex]\angle GED\cong \angle DEH[/tex]

Bisector of an angle of a triangle theorem states that an angle bisector of a triangle divides the opposite side into segments that are proportional to the adjacent sides.

In triangle FEH, ED is an angle bisector

[tex]\frac{EH}{EG}=\frac{DH}{GD}[/tex]

[tex]\frac{112}{99.2}\times 62=x+2[/tex]

[tex]70=x+2[/tex]

[tex]70-2=x[/tex]

[tex]68=x[/tex]

Therefore the value of x is 68 ft.

Two travellers spend from 12 o'clock to 6 o'clock walking along a level road, up a hill and back again. Their pace is 4 mph on the level, 3 mph uphill, and 6 mph downhill.

How far do they walk and at what time do they reach the top of the hill?

Answers

12 oclock to 6 oclock is 6 hours

d = distance
r = rate of speed

time to walk uphill : t1 = d/3
time to walk downhill: t2 = d/6
total distance = 2d ( up hill and down ill)
2d = (d/3 + d/6)r
2/(1/3 +1/6) = r
r = 4
average speed up and down the hill was 4 mph

total distance = (2/3 x 6 x 4) + (1/3 x 6 x 4)
total distance = 16 + 8 = 24 miles total

Average speed to top of hill = 2/(1/4 +1/3) = 3.43 mph

to top of hill = 24/2 = 12 miles

12 / 3.43 = 3.5 hours
12 oclock + 3.5 hours = 3:30

total miles was 24
arrived at top of hill at 3:30
ime to walk uphill : t1 = d/3
time to walk downhill: t2 = d/6
total distance = 2d ( up hill and down ill)
2d = (d/3 + d/6)r
2/(1/3 +1/6) = r
r = 4
average speed up and down the hill was 4 mph

total distance = (2/3 x 6 x 4) + (1/3 x 6 x 4)
total distance = 16 + 8 = 24 miles total

Average speed to top of hill = 2/(1/4 +1/3) = 3.43 mph

to top of hill = 24/2 = 12 miles

12 / 3.43 = 3.5 hours
12 oclock + 3.5 hours = 3:30

total miles was 24
arrived at top of hill at 3:30

Tan θ = 30/100
       θ =  16.70, but since it is in an anticlockwise direction it will be -16.7
using Pythagoras theorem

thus, c²=100²+30²

Answers

Laptops are 1200 each and cameras are 500 each.

Using elimination:
3c+l=2700
5c+2l=4900

We will make the coefficients of l the same by multiplying the top equation by 2:
2(3c+l=2700)
6c+2l=5400

Our system is now
6c+2l=5400
5c+2l=4900

Subtract the bottom equation:
6c+2l=5400
-(5c+2l=4900)

We have
1c=500
So each camera is 500.

Substitute that in our original first equation:
3(500)+l=2700
1500+l=2700
1500+l-1500=2700-1500
l=1200

A rectangle has a a perimeter of 72 ft. The length and width are scaled by a factor 3.5.



What is the perimeter of the resulting rectangle?



Enter your answer in the box.

Answers

Formula for perimeter of rectangle:
P=2(L+w)
P=2L+2w
Here Perimeter, p= 72 ft
And scale factor of length and width=3.5 which means rectangle is enlarged.
So perimeter of rectangle= 3.5 x 72
P=252ft 

Answer: 252 ft

We know the perimeter of the original rectangle is 72ft.
We also know that the perimeter P of the rectangle is defined as:
P=2L+2W.
So P is directly proportional to L+W. This means that if L or W were to get bigger, P will get bigger, and if L or W were to get smaller P will get smaller.

The question also states that both L and W are scaled by the same factor of 3.5 .
This means the sum of the dimensions L+W is scaled by 3.5
It also means that the perimeter is upscaled by 3.5 as it is proportional to L+W.
P = 72 ft × 3.5 = 252 ft.

252 ft is the answer.

The positive integer is [tex]3[/tex]

Let the number be [tex]a[/tex]

square of [tex]a = a^{2}[/tex]

Square of [tex]3[/tex] more than [tex]a[/tex] = [tex](3+a)^{2}[/tex]

[tex](3 + a)^{2} = (3+a)(3+a) = 9 + 3a + 3a + a^{2} = a^{2} + 6a + 9[/tex]

[tex]a^{2} + a^{2} + 9a + 9 = 45[/tex]

[tex]2a^{2} + 6a + 9 = 45[/tex]

Subtract 9 from both sides :

[tex]2a^{2} + 6a = 45 - 9[/tex]

[tex]2a^{2} + 6a = 36[/tex]

Divide through by 2

[tex]a^{2} + 3a = 18\\a^{2} + 3a - 18 = 0[/tex]

Factorize :

[tex]a^{2} + 6a - 3a - 18 = 0\\a(a + 6) - 3(a + 6) = 0\\a + 6 = 0\\or\\a - 3 = 0[/tex]

[tex]a = 3 ;\\or\\a = - 6[/tex]

since, a is a positive integer, then [tex]a = 3[/tex]

In two or more complete sentences, explain whether or not the domains of the two functions are the same.

Answers

We have that the logarithmic function has a domain from 0 (without including 0) to plus infinity. That is because of the property that e=2.71 raised to any power is positive. We also have that the square root function is defined only from 0 to plus infinity, since every square of a number is positve or 0. The answer is that the domains differ; they are almost equal, except for the fact that the domain of the square root function additionally contains 0.

Jackson currently has $35 in his bank account , he is saving $15 a week to eventually buy a new cell phone. He can represent the amount in his account with the equation y=15x+35.
I also need help answer the other questions to

Answers

X represents the number of weeks he has been saving Y is the total money in his account the slope is $15 and the Y intercept is $35 for the the starting balance in his account

Answer:

1. We have our function y = 15x + 35

a) Where the x represents the numbers of weeks since each week he is saving $15, which is the independent variable.

b) Where the y represents the total money he has, which is the dependent variable.

c) the slope is 15, as x increments, the slope goes up by 15.

d) The y-intercept is 35, because when x = 0, y = 35.

2. To create the table you have to find the value of y, knowing the values of x.

Using our function, when x = 0

y = 15(0) + 35

y = 0 + 35

y = 35

Using our function, when x = 1

y = 15(1) + 35

y = 15 + 35

y = 50

Using our function, when x = 2

y = 15(2) + 35

y = 30 + 35

y = 65

Using our function, when x = 3

y = 15(3) + 35

y = 45 + 35

y = 80

Using our function, when x = 4

y = 15(4) + 35

y = 60 + 35

y = 95

Using our function, when x = 5

y = 15(5) + 35

y = 75 + 35

y = 110

Yes, the table is proportional, because for each week, the value of his money is increasing by 15.

3. To create the graph, you can put the values of the table into the graph

And the graph is not proportional because to be proportional the relationship between “x” and “y” should be constant, meaning that, if “x” changes, “y” changes by the same percentage.

In this case our function has an intercept of 35 meaning that at week 0, he has $35 saved,

after a week: $50,

after two weeks: $65,

So, although is linear, is not proportional because when you double the weeks saved, you don't double the money saved.

Answer: The answer is  1 and 3.

Step-by-step explanation:  We are to select the correct options about the number of real roots of a cubic function.

We know that there are three roots of a cubic function, out of which one must be real because the least number of real roots of an odd degree function is 1.

Also, if the second root is real, then the third one must also be real because the complex roots of a function occur in pairs.

Therefore, there is one real root or three real roots for a cubic function.

Thus, the answer is 1 and 3.
