If MN = x+4 and DE = 3x-2, find x. (More info in pic)

Answers

Answer:  D) 10

============================================================

Explanation:

I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.

So,

DE = 2*(MN)

3x-2 = 2*(x+4)

3x-2 = 2x+8

3x-2x = 8+2

x = 10

. If you walk around a circular path TWICE, and the circle has a diameter of 100 m, how far did you walk in TOTAL?

Answers

The total distance traveled was 638.3m.

How to calculate the distance traveled?

To calculate the perimeter of a circle we perform the following operations:

We must keep in mind that the radius of a circle is equal to half the diameter, so the radius of this circle is 100m divided by 2.

100m ÷ 2 = 50m

So the radius of this circle is 50m.

Subsequently, to find the perimeter of the circle we apply the following formula:

2 × π × radius of the circle = perimeter of the circle.

2 × 3.14 × 50 = 314.15m

According to this operation, the distance traveled in one lap would be 314.15m. So in two turns it would be:

314.15m × 2 = 638.3m

Let's look at the statement.

7y = 14x  and  y = 2x does have infinitely many solutions. Why? Because the first equation can be rearranged to look like the second one. If you divide 7y and 14x by 7, you end up with y = 2x. Look familiar? This means the set of equations has infinitely many solutions.

Suppose that a homeowner notices a 20 percent increase in the water bill for July. The homeowner traces this increase to four sources: a running toilet, a dripping faucet, a guest who visited for two days, and a broken sprinkler head. Further study shows that the broken toilet accounts for 8 percent of the increase, the faucet 2 percent, and the visiting guest 4 percent. The homeowner concludes that the remaining 8 percent is attributable to the broken sprinkler head. What method did the homeowner use in drawing this conclusion

Answers

Answer:46

Step-by-step explanation:

Homeowner should use in drawing the conclusion is method of residues.

What is method of residues?

A complex series of occurrences is removed from all known causes. The reason is supposed to be what is left over.

If a set of factors is thought to create a set of phenomena, and all but one of them matches all the phenomena, the remaining phenomenon can be attributed to the remaining factor.

A method of agreement is a way of comparing different examples of the same phenomenon under different conditions.

The method of concurrent variation states that if a specific effect occurs in a variety of settings,

Thus, homeowner should use in drawing the conclusion is method of residues.

A cyclist is riding a bicycle whose wheels have a diameter of 2.1 feet. Suppose the wheels turn at a rate of 260 revolutions per minute. (a) Find the angular speed of the wheels in radians per minute. (b) Find the speed of the cyclist in feet per minute. Do not round any intermediate computations, and round your answer to the nearest whole number.

Answers

Answer:

a.1633rad/min

b.1715feet/min

Step-by-step explanation:

We are given that

Diameter of wheel, d=2.1 feet

Radius of wheel, r=[tex]\frac{d}{2}=\frac{2.1}{2}[/tex]feet

Rate=260 rev/min

a. We have to find the angular speed of the wheel in rad/min

1 rev=[tex]2\pi[/tex]radian

Where [tex]\pi=3.14[/tex]

Using the value

Angular speed=[tex]260\times 2\times 3.14/min[/tex]

Angular speed,[tex]\omega=1633rad/min[/tex]

(b)

Speed=[tex]r\omega[/tex]

Using the formula

Speed of  the cyclist=[tex]\frac{2.1}{2}\times 1633[/tex]feet/min

Speed of  the cyclist=1714.65[tex]\approx 1715[/tex]feet/min

37 1/2 is what percent of 5

Answers

Answer:

750%

Step-by-step explanation:

We know that 100% of 5 is 5,

200% of 5 is 10,

300% of 5 is 15,

400% of 5 is 20,

500% of 5 is 25,

600% of 5 is 30,

700% of 5 is 35,

800% of 5 is 40.

So 37 1/2 percent of 5 must be between 700 and 800 percent of 5. We also know that 2.5 is 50% of 5, and 35 + 2.5 = 37.5. So 37 1/2 is 750% of 5

Write an exponential function in the form y=ab^x that goes through points (0,6) and (5, 6144)

Answers

Given:

An exponential function goes through points (0,6) and (5, 6144).

To find:

The exponential function.

Solution:

The general form of an exponential function is

[tex]y=ab^x[/tex]          ...(i)

It goes through points (0,6) and (5, 6144). It means the equation must be satisfied by these two points.

Putting x=0 and y=6, we get

[tex]6=ab^0[/tex]

[tex]6=a[/tex]

Putting a=6, x=5 and y=6144, we get

[tex]6144=6b^5[/tex]

[tex]\dfrac{6144}{6}=b^5[/tex]

[tex]1024=b^5[/tex]

Taking 5th root on both sides, we get

[tex]\sqrt[5]{1024}=b[/tex]

[tex]4=b[/tex]

Putting a=6 and b=4, we get

[tex]y=6(4)^x[/tex]

Therefore, the required exponential function is [tex]y=6(4)^x[/tex].
