Estimate the circumference of the circle to the nearest hundredth. Use 3.14 the diameter is 11

Answers

Answer 1

Recall the circumference formula:
[tex]c= \pi D[/tex]
Now, plug in pi as 3.14 and D as 11:
[tex]3.14 * 11 = 34.54[/tex]
Your answer is 34.54.

Answer 2

Final answer:

The circumference of a circle with a diameter of 11 using 3.14 for pi is estimated to be 34.54 to the nearest hundredth.

Explanation:

To estimate the circumference of a circle to the nearest hundredth, we use the formula C = πd, where C is the circumference and d is the diameter of the circle. Given that the diameter is 11 and we should use 3.14 for π, the calculation is C = 3.14 × 11. Performing the multiplication gives us a result of 34.54, which is the estimated circumference of the circle to the nearest hundredth.

14x-(6+7x)

(Simplify answer)

Answers

14x-(6+7x)
=14x-6-7x
=14x-7x-6
=(14x-7x)-6
=7x-6x

We can simplify an expression by distributing if needed and combing terms if needed.

In the expression 14x - 6 + 7x the terms 14x and 7x are like terms. Because they both have the same variable and are to the same power.

14x - 6 + 7x
21x - 6

So, 21x - 6 is the answer.

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

Answers

(12(0.08)+x(0.2))/(12+x)=0.16 perform indicated multiplication on left side

(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.

How many dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil?

Answers

the answer is 48 dollars more

Answer:

The number of dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil is:

$ 48

Step-by-step explanation:

Brand A--

Number of bottles (x) Price (dollars) y

2 22

3 33

4 44

5 55

The function that represents the relation between the price of the bottles and the number of bottles is:

y=11x

Brand B--

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

and according to Brand B the price of 8 bottles is: y=17×8= $ 136

Also, the difference in the price of Brand B to that of Brand A for 8 bottles is:

$ 136-$ 88

= $ 48

Starting at home, Jessica traveled uphill to the grocery store for 18 minutes at just 20 mph. She then traveled back home along the same path downhill at a speed of 60 mph.

What is her average speed for the entire trip from home to the grocery store and back?

Answers

The average speed is 40 miles per hour.

Based on the formula [tex]distance = velocity*time[/tex] we can find the distance from the grocery store:

[tex]distance = velocity * time = 20mph * \frac{18}{60}hrs = 6 miles[/tex]

Based on this distance we can find the time it took her to get back using the formula [tex]time = \frac{distance}{velocity}: [/tex]

[tex]time = \frac{distance}{velocity} = \frac{6 miles}{60mph} = \frac{1}{10}hrs = 6 minutes[/tex]

After this you just take the average of Jessica going at 20 mph for 18 minutes and 60 mph for 6 minutes:

[tex]\frac{20mph * 18min + 60mph*6min}{24min} = 30mph[/tex]

C+1/c-2 = 4/7 please show how you got the answer which is 5

Answers

Assuming the equation is (c+1)/(c-2) = 4/7, the answer is actually c = -5

(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.

The weight of 10 identical samples of a substance is 0.01 pound what is the weight of 10,000 samples

Answers

We use ratios here.

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.

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.

A man owned 5/8 of an interest in a house. He sold 1/5 of his interest, at a cost for $1000. What is the total value of the house? Explain how u solved it.

Answers

First you would have to find a common denominator with 1/5 and 5/8, which would be 40. So, they would now be 8/40 and 25/40. If 8/40 is $1,000, then you need to figure out how many 8/40 you need to get 40/40. You need 5 8/40, so you multiply $1,000 by 5 to get $5,000, which is the answer.

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

Refer to the diagram shown below.

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)

Hello there!

-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

Answers

In any case, divide by three: equilateral=same sides, triangle=3 sides

Let x represent one side of equilateral triangle.
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!
