Answer:
e = -4
step-by-step explanation:
2e + 3 + 7 = 2
2e + 10 = 2
2e = 2 - 10
2e = -8
e = -8/2
e = -4
verification:
2e + 3 + 7
2(-4) + 3 + 7
-8 + 10
2 ... Therefore proved.
Answer:
e = -4
Step-by-step explanation:
2e + 3 + 7 = 2
2e + 7 = -1
2e = -8
e = -4
First I subtracted the 3 off both sides to keep the equation equal getting me -1. Then i subtracted off the 7 from both sides getting me -8. Finally, i divide both sides by 2 and get -4. E will equal -4.
Have an amazing day!!!

Once a week, Dianne spends 5 hours making windchimes.
It takes her 30 minutes to make a small windchime and 40
minutes to make a large windchime. This week, Dianne
will make twice as many small windchimes as large
windchimes. How many of the small windchimes will
Dianne make this week?
Let's take No. of large windchime be x
then no. of small windchime be 2x
now, time taken to make one large windchime is 40min and time taken to make one small windchime is 30min.
Total time is 5 hours = 300 min
so time taken to make all large chimes= 40x
time taken to make small chimes = 30*2x= 60x
total time = 300 min
40x + 60x = 300
100x = 300
x = 300/100
x = 3
total small windchimes = 2x = 2*3=6
total large windchimes = x = 3.
so I hope it's helpful. It really took some time

What is the perimeter?
Answer:
19.25 inches
Step-by-step explanation:
x^2 + 5^2 = 8^2= 64
25+ x^2 = 64
x^2 = 64-25= 39
x = 6.24
perimeter = 19.24

BC = 5 inAC = 8inAB = x (in)[tex] \\ [/tex]
☆To find :[tex] \\ [/tex]
Perimeter of triangle[tex] \\ [/tex]
☆Solution:[tex] \\ [/tex]
So to find perimeter of triangle first we have to find value of x.
[tex] \\ [/tex]
As it's Given one angle is 90°
So we can find value of x by using this formula:-
[tex] \\ [/tex]
Hypotenuse ² = Base² + perpendicular ²
[tex] \\ [/tex]
Where :-
Hypotenuse is AC
Base is BC
Perpendicular is AB
[tex] \\ [/tex]
So:-
[tex] \\ [/tex]
⇢AC² = BC² + AB²
[tex] \\ [/tex]
⇢8² = 5² + x²
[tex] \\ [/tex]
⇢64 = 5² + x²
[tex] \\ [/tex]
⇢64 = 25 + x²
[tex] \\ [/tex]
⇢25 + x² = 64
[tex] \\ [/tex]
⇢x² = 64 - 25
[tex] \\ [/tex]
⇢x² = 39 in.
[tex] \\ [/tex]
⇢x = √(39)
[tex] \\ [/tex]
⇢x = 6.2
[tex] \\ [/tex]
Now Let's find perimeter of triangle.
We know :-
Perimeter of triangle = Side one + side two + side 3
[tex] \\ [/tex]
So:-
[tex] \\ [/tex]
⇢Perimeter of triangle = AB + BC + AC
[tex] \\ [/tex]
⇢Perimeter of triangle = 5 + 8 + 6.2
[tex] \\ [/tex]
⇢Perimeter of triangle = 13 + 6.2
[tex] \\ [/tex]
⇢Perimeter of triangle = 19.2 in.

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.

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 are the values of b and c?
Since a= 10, we know that b = 4a - 5
--> b = 4(10) - 5 = 40 - 5 = 35
By looking at the table at the left, the value of of c that goes with a when a = 10 is
--> 19.
So b = 35 and c = 19.

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
