Mohammed built a building that can carry up to 5 tons. If each person weighs about 150 pounds, how many people can fit onto the building that Mohammed built?
Answer:
Step-by-step explanation:
To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).
2,000 lbs. = 1 T.
X 5 X 5
10,000 lbs. = 5 T.
Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.
10,000/150=66.6666666667

Leroy wants to buy a new racing bicycle that costs $168. To earn money, he can either do yardwork for his grandmother or babysit his brother and sister. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting. How much longer will it take him to earn the money if he only does yardwork for his grandmother?
______ hours
PLEASE HELP DUE AT 11:59 PLEASE
Answer:
7 hours
Step-by-step explanation:
This is because 24/3=8
48/4=12
168/12=14
168/8=21
21-14=7
It take him 7 hours to earn the money if he only does yardwork for his grandmother.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Leroy wants to buy a new racing bicycle that costs $168. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting.
We need to find the time take to earn the money if he only does yardwork for his grandmother.
Thus, $24 for 3 hours of yardwork
24/3=8
Again, $48 for 4 hours of babysitting.
48/4=12
Now, 168/12=14
168/8=21
The time difference is;
21-14=7

Michelle simplified an expression for the perimeter of the rectangle below and got 5/6x + 35. Explain her error, and include the correct expression for the perimeter.
The width is 5/6x+23 and the Height is 12.
Answer:
Michelle didn't double the height and width for the perimeter and the correct expression is:
[tex]\frac{5}{3}x+70[/tex]
Step-by-step explanation:
Given
Length = l = 5/6x+23
Width = w = 12
The perimeter of a rectangle is given by:
[tex]P = 2(l+w)[/tex]
Putting the values, we get
[tex]P = 2\{(\frac{5}{6}x+23)+12\}\\\\P = 2(\frac{5}{6}x+23+12}\\P =2(\frac{5}{6}x+35)\\P = 2*\frac{5}{6} + 2* 35\\P =\frac{5}{3}x+70[/tex]
The length and width had to be doubled for the perimeter which Michelle didn't.
Hence,
Michelle didn't double the height and width for the perimeter and the correct expression is:
[tex]\frac{5}{3}x+70[/tex]
Answer:

3x-y=5
write each equation in slope-intercept form
Answer:
y = 3x - 5
Step-by-step explanation:
3x-y=5
-3x -3x
-y= -3x + 5
divide each number by -1
-y/-1 = y
-3x/-1 = 3x
5/-1 = -5
The equation 3x - y = 5 can be converted to slope-intercept form as follows: y = 3x - 5
Given is an equation 3x - y = 5, we need to convert it in slope-intercept form.
To convert the equation 3x - y = 5 into slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate the variable "y" on one side of the equation.
Let's rearrange the given equation step by step:
Starting with 3x - y = 5, we can begin by moving the term involving "x" to the other side:
3x - y + y = 5 + y
Simplifying:
3x = y + 5
Now, let's isolate "y" by subtracting "y" from both sides:
3x - y = y + 5 - y
Simplifying:
3x - y = 5
To eliminate the "y" term on the left side, we can add "y" to both sides:
3x - y + y = 5 + y
Simplifying:
3x = 5 + y
Next, let's rearrange the equation to have "y" on the right side:
3x = y + 5
We can write this equation as:
y = 3x - 5
Now the equation is in slope-intercept form (y = mx + b), where the slope "m" is 3, and the y-intercept "b" is -5.

parents are late.
t=150 +0.5m
Which of the following solutions shows an amount of money Lili can
reasonably expect to earn each day?
Answer:
$150
Step-by-step explanation:
[tex]t=150 + 0.5m\\t=150+0.5*0\\t=150[/tex]
This is as we don't know how often the parents are late, nor if they are late. So we assume that the parents are never late.

what is the rate of change in y= 2x+3
Answer:
The Answer is 2
EXPLANATION:
y(x)=2x+3
y(x+Δx)=2(x+Δx)+3
=2x+2Δx+3
Δy=y(x+Δx)−y(x)
=(2x+2Δx+3)−(2x+3)
=2Δx
⇒Δy=2Δx, Δy/Δx =2
The rate of change in the equation of a line in slope-intercept form
y = 2x + 3 is 2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An equation of a line y = 2x + 3.
This is in slope-intercept y = mx + b, where 'm' is the slope.
Therefore, The rate of change in y = 2x + 3 is 2.

So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one

how can I find the slope to this I need help
Answer:
Your slope is -1
Step-by-step explanation:
Find the change in x and the change in y and put it in change in y over change in x.
Δx = -1 - -2 = 1
Δy = -1 - 0 = -1
Slope = rise over run = Change in y over change in x = Δy/Δx = -1/1
Therefore the slope is -1/1 which is written as just -1
