how many solutions does the system of equations have explain 2.5(x+4)=4.1x+16-1.6x

Answer:

B) -8

Step-by-step explanation:

Slope is rise/run, or the difference in y over the difference in x, so to solve this:

Take the y value of one of the points and subtract it from the other, and divide it by the same thing with the x values

[tex]\frac{9-1}{6-7} =\frac{8}{-1} =-8[/tex]

No, Brianna is not correct.

The distance around the pool is 131.4 ft

The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius, and, 2r=d is diameter.

P=(πr + 2r)

here, we have,

1) Semi circle with a diameter equal to the side opposite it, 20 ft.

Find the length of half the circle:

Circumference of semi-circle = (1/2)(πd)

Where:

π = 3.14

d = 20 ft.

Circumference of semi-circle = (1/2)(3.14)(20 ft) = 31.4 ft.

2) Vertical lengths from the endpoint of semi-circle to the endpoints of horizontal lengths, 40 ft each ⇒ 2 × 40 ft. = 80 ft.

3.) Horizontal length at 20 ft.

Add the semi-circle, vertical, and horizontal lengths:

Distance around the pool = 31.4 ft + 80 ft. + 20 ft.

Distance around the pool = 131.4 ft.

Answer:

one blue candle. 1/12 probability.

Step-by-step explanation:

if they are as likely as not to select a green candle, then there are 6 green ones. so now we have accounted for 11 if I am right, so only one can be blue

It is equally likely as not that the customer will select a blue candle.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

Let the number of green candles on the tray be G, and the number of blue candles be B.

We know that there are 12 candles in total on the tray, so:

G + B = 12 (total number of green and blue candles is 12)

G/(G+B) = 1/2 (as the probability of selecting a green candle is equal to the probability of selecting a non-green candle)

We can use these two equations to solve for G and B:

G + B = 12

G = (12 - B)

Substituting into the second equation:

(12 - B) / (12 - B + B) = 1/2

(12 - B) / 12 = 1/2

12 - B = 6

B = 6

So there are 6 blue candles on the tray.

Since there are 12 candles in total, and 6 of them are blue, the probability of selecting a blue candle at random is:

P(selecting blue) = B / (G + B) = 6 / 12 = 1/2

Therefore,

It is equally likely as not that the customer will select a blue candle.

This means that the probability of selecting a blue candle is 50-50, which is neither impossible nor certain, but rather equally likely as selecting a green candle.

Answer:

13.2 miles

Step-by-step explanation:

To solve this, we will need to first solve for the base of the triangle and then use the information we find to solve for the shortest route.

(5.5 + 3.5)² + b² = 15²

9² + b² = 15²

81 + b² = 225

b² = 144

b = 12

Now that we know that the base is 12 miles, we can use that and the 5.5 miles in between Adamsburg and Chenoa to find the shortest route (hypotenuse).

5.5² + 12² = c²

30.25 + 144 = c²

174.25 = c²

13.2 ≈ c

Therefore, the shortest route from Chenoa to Robertsville is about 13.2 miles.

Answer:

(−6)²

Step-by-step explanation:

(−6)⋅(−6)

This means the numbers are being multiplied.

A number is being multiplied by the same number. You can write an exponent for the number of times it's being multiplied by itself.

Example:

x = x¹

x·x = x²

x·x·x = x³

You are multiplying (−6) twice.

(−6)⋅(−6) = (−6)²

if she uses 1/3 for one she uses 2/3 for 2 because 1/3 times 2 is 2/3

step 1 Address formula, input parameters & values

1/3 and 2/1

1/3 times 2= ?

step 2 Multiply both numerators
