An equilateral triangle has a perimeter of 15x3 + 33x5 feet. What is the length of each side? x3 feet
Answers
Next, we know that the perimeter of the equilateral triangle= side+side+side,so
P=x+x+x with the P=15x^3+33x^5 feet
15x^3+33x^5=3x
Divided both side by 3
(15x^3+33x^5)/3=3x/3
x=5x^3+11x^5
x=x³(5+11x²) feet. As a result, the length of each side is x³(5+11x²) feet. Hope it help!

Also, the price of the bottles depending on the number of bottles is:
Y=17x
According to Brand A the price of 8 bottles is: y=11×8=$ 88

The weight of 10 identical samples of a substance is 0.01 pound what is the weight of 10,000 samples
Answers
For every 10 samples, the total weight is 0.01 lb.
We write
10 / 0.01.
We want to find the weight of 10,000 samples.
We write
10,000/?
These two ratios must equal each other.
(10 / 0.01) = (10,000 / ?)
If you know how to cross-multiply, then we can do that here.
0.01 * 10000 = 10 * ?
100 = 10 * ?
The unknown value is 10, which is your answer.
The weight of 10,000 samples is:
10 pounds.
Step-by-step explanation:It is given that:
The weight of 10 identical samples of a substance is 0.01 pound.
i.e. 10 samples= 0.01 pound.
Now we are asked to find the weight of 10,000 samples.
Since,
10 samples= 0.01 pound.
1000×10 samples= 1000×0.01 pounds
i.e.
10000 samples= 10 pounds.
Hence, the answer is: 10 pounds.
−5=−8−x What is x? Solve for x
Answers
-5 = -8 -x
First, we need to get x isolated (put on one side of the equation by itself), and then divide by -1 to get rid of the negative sign.
Add 8 to both sides.
-5 + 8 = 3
-8 + 8 = 0
You are left with:
-x = 3
Now, we must divide both sides by -1 to solve for x.
-x / -1 = x
3 / -1 = -3
You are now left with the following solution:
x = -3

(–2, –16), (0, –12)
(–6, 0), (–2, –16), (2, 0)
(0, –12), (–6, 0), (2, 0)
Answers
Answer:
x-intercepts are (-6,0 and (2,0)
First option is correct.
Step-by-step explanation:
The given equation is [tex]y=x^2+4x-12[/tex]
For x-intercept, y=f(x)=0. Thus, we have
[tex]0=x^2+4x-12[/tex]
We can split the middle term as 4x = 6x-2x
Thus, the equation becomes
[tex]x^2+6x-2x-12=0[/tex]
Now, we make group
[tex](x^2+6x)+(-2x-12)=0[/tex]
Take GCF from each of the group
[tex]x(x+6)-2(x+6)=0[/tex]
Factored out the common term
[tex](x+6)(x-2)=0[/tex]
Apply the zero product property,
[tex]x+6=0,x-2=0[/tex]
Solve for x
[tex]x-6,x=2[/tex]
Thus, x-intercepts are (-6,0 and (2,0)
First option is correct.

C+1/c-2 = 4/7 please show how you got the answer which is 5
Answers
(c+1)/(c-2) = 4/7
7*(c+1) = 4*(c-2) ... cross multiply
7c+7 = 4c-8
7c+7-7 = 4c-8-7 ... subtract 7 from both sides
7c = 4c-15
7c-4c = 4c-15-4c ... subtract 4c from both sides
3c = -15
3c/3 = -15/3 ... divide both sides by 3
c = -5
----------------------------
Check:
(c+1)/(c-2) = 4/7
(-5+1)/(-5-2) = 4/7 ... replace every copy of 'c' with '-5'
(-4)/(-7) = 4/7
4/7 = 4/7 .. true equation; answer checks out
So the answer of c = -5 has been confirmed.

an airplane is flying from montreal to vancouver. the wind is blowing from the west at 60km/h. the airplane flies at an airspeed of 750km/h and must stay on a heading of 65 degrees west of north. what heading should the pilot take to compensate for the wind? what is the speed of the airplane relative to the ground?
Answers
In order for the airplane to maintain a heading of 65° west of north, it actually heads at (65° +x) west of north at a speed of 750 km/h, to compensate for the wind blowing from west t east at 60 km/h.
The actual speed of the airplane relative to the ground is V km/h.
From geometry, obtain the triangle shown.
The speed of 750 km/h is opposite an angle of 155°, and the unknown angle x is opposite the wind speed of 60 km/h.
From the Law of Sines, obtain
[tex] \frac{sin(x)}{60}= \frac{sin(155^{o}}{750} \\ sin(x)= (\frac{60}{750})sin(155^{o})=0.0338[/tex]
[tex]x=sin^{-1}0.0338=1.937^{o}[/tex]
The heading that the pilot should take is 65 + 1.937 = 66.94° west of north.
The third angle of the triangle is 180 - (155 + 1.937) = 23.063°.
Use the Law of Sines to calculate V.
[tex] \frac{V}{sin(23.063^{o})}= \frac{750}{sin(155^{o})} [/tex]
[tex]V=( \frac{sin(23.063)}{sin(155)} )750=695.21\,km/h[/tex]
Answer:
The pilot heads approximately 67° (nearest integer) west of north.
The speed of the airplane relative to ground is 695.2 km/h (nearest tenth)

The number 6,007,200 in expanded form is written as 6,000,000 + 7,000 + 200, breaking down the number by each digit's place value.
To write the number 6,007,200 in expanded form, we break it down based on the place value of each digit. Here is how you would write it:
Identify the value of each digit in the number.
Starting from the left, write each digit multiplied by its place value.
Add each of these values together.
Applying this to the number 6,007,200, we get:
6,000,000 (6 millions) + 7,000 (7 thousands) + 200 (2 hundreds)
Therefore, the expanded form of 6,007,200 is:
6,000,000 + 7,000 + 200
Roman mixes 12 liters of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. Find the number of liters of 20% acid solution in the new mixture. Construct a table to organize the information, and show all of your work to solve the problem

(0.96+0.2x)/(12+x)=0.16 multiply both sides by (12+x)
0.96+0.2x=1.92+0.16x subtract 0.16x from both sides
0.96+0.04x=1.92 subtract 0.96 from both sides
0.04x=0.96 divide both sides by 0.04
x=24
So 24 liters of 20% acid solution is in the new mixture.
