Henry saved 25% of his paycheck last week. If his paycheck was $800, how much did he save?
this is almost due so i really need the help thank you
You need to paint your house to sell it. You can choose between two different painters, George and Henry. George will charge 90$ for the paint, and then $40 per hour. Henry will charge $120 for the paint and then $35 per hour.
After how many hours will the cost be the same?
If you estimate it will take about 10 hours to paint the room, who should you choose?
Answer:
At 6 hours the cost is the same. At 10 hours of service Henry is cheaper.
Step-by-step explanation:
This is simple. Follow my lead!
First we must create an equation for George
He charges $90 initially and then $40 per hour
So George's equation is:
[tex]y = 40x + 90[/tex]
Now let's find Henry's equation!
He charges $120 initially and then $35 per hour
So Henry's equation is:
[tex]y = 35x + 120[/tex]
1) To find when they will be the same, just set them equal to each other and solve for x.
[tex]40x + 90 = 35x + 120 \\ - 35x \\ 5x + 90 = 120 \\ - 90 \\ 5x = 30 \\ \div 5 \\ x = 6[/tex]
This means that when x = 6 or at 6 hours in the cost is the same!
2) Just solve both equations with x = 10
[tex]y = 40(10) + 90 \\ y = 400 + 90 \\ y = 490[/tex]
At 10 hours George's service costs $490!
[tex]y = 35(10) + 120 \\ y = 350 + 120 \\ y = 470[/tex]
At 10 hours Henry's service costs $470!
$470 is less than $490 so that means Henry is more cheaper!
Yay! We did it!

what is the equation of the line that passes through the point (-3,-8) and has a slope of 4?
please help
Step-by-step explanation:
the easiest approach with a given point and the slope of the line is the point-slope form :
y - y1 = a(x - x1)
where "a" is the slope, and (x1, y1) is a point on the line.
so, we get
y - -8 = 4(x - -3)
y + 8 = 4(x + 3)
if we need the slope-intercept form
y = ax + b
we now simplify the point-slope form
y + 8 = 4x + 4×3 = 4x + 12
y = 4x + 4

Answer:
Step-by-step explanation:
If we think about a right triangle, we get that the hypotenuse is 24ft or the length of the ladder. The base of the ladder is 15ft away from the building which is the leg of the right triangle. The screenshot is the diagram (my drawing isn't that good lol:))
Thus we can use cosine function with the angle between the ladder and the ground since we need to find the angle and we get
[tex]cos\alpha = \frac{15}{24}[/tex]
and [tex]\alpha = 51.3 degrees[/tex]
The angle is 51.3 degrees hope that helps!

What’s the correct one? I have no idea please help
Answer:
22π cm³
Step-by-step explanation:
Let's start with the formulas for volume:
volume of cylinder = πr²h
volume of cone = (1/3)πr²h
Notice the formulas above for the volume of a cylinder and the volume of a cone. The only difference is that the volume of the cone has the fraction 1/3 multiplying the rest, and the rest is exactly the same as in the volume of the cylinder.
That means that if a cylinder and a cone have the same radius and height, the volume of the cone is 1/3 the volume of the cylinder.
Here, the cylinder and cone do have the same radius and height. That means the volume of the cone is 1/3 the volume of the cylinder.
The volume of the cylinder is 66π cm³.
The volume of the cone is 1/3 of that volume, so divide 66π cm³ by 3 to find it.
volume of cone = 66π cm³ / 3 = 22π cm³
Answer: 22π cm³

James is seeking a loan with a simple interest rate of 3% per year. If he wants to borrow $8,000, then how much will he be charged in interest after 4 years?
Answer:
960
Step-by-step explanation:
I used a calculator but its 3% of $8,000 (which I'm pretty sure is 8,000 divided by 3) x 4 so in that's 240x4 which equals 960. Hope this helps have a good day!
Answer:
$960
Step-by-step explanation:
Simple interest is interest that goes up the same amount each period. The formula for simple is A=P(1+rt), where is A is the total amount, P is the principal (aka initial amount), r is the rate (in decimal form), and t is the time.
So, to solve we can use the equation, A=8000(1+0.03*4). In this equation A=8960, meaning that in 4 years the total amount owed, including the initial loan, will be $8960. Since the difference between the principal and the total amount is 960, $960 is the amount paid in interest.

What is the future value if $18733 is invested at 5.1% for 10 years, compounded quarterly
Answer:
Step-by-step explanation:
The compound interest formula is [tex]P(1+r/n)^{nt}[/tex]
P: the initial amount of cashr: interest raten: # of times that interest is compounded per time periodt: # of time periodsKnown information:
P: 18733r: 5.1% or 0.051n: quarterly or 4t: 10 yrsNow let's set up the equation:
Future amount: [tex]18733 (1+\frac{0.051}{4} )^{4*10}[/tex] [tex]=31,095.49[/tex]
Thus the future amount is $31.095.49.
