You traveled up the river at 56 feet a minute and down the river at 47 feet a minute.

The question is asking us to simply convert the speed traveled in feet per second to feet per minute. To do that, we say,

28 feet in 30 seconds, if we multiply both by two. We have 56 feet in 60 seconds. Also remember that 60 seconds make 1 minute. Thus, you must have kayaked up the river at 56 feet in a minute.

423 feet in 9 minutes, if we divide both by nine. We have 47 feet in a minute. This means that you kayaked 47 feet a minute down the river.

Answer:

  6/45 and 20/45

Step-by-step explanation:

The least common denominator is the least common multiple (LCM) of 9 and 15.

The factors of those numbers are ...

  9 = 3·3

  15 = 3·5

The LCM is the product of the unique factors to their highest powers:

  3·3·5 = 45

__

To make 2/15 have a denominator of 45, we need to multiply by 3/3:

  2/15·3/3 = 6/45

To make 4/9 have a denominator of 45, we need to multiply by 5/5:

  4/9·5/5 = 20/45

The desired fraction pair is 6/45 and 20/45.

Step-by-step explanation:

If the males make up 60% of the class then

The females make up 100 - 60 = 40% of the class.

Females = 40% * x        where x = the class size.

380 = 40/100 * x

Answer:

correct.

Step-by-step explanation:

Answer:

Parallel

Step-by-step explanation:

So if they have the same slope but different y-intercepts, it would be parallel because the slope stays the same so the line doent change, just the starting point

for example use the following equations

y = x + 2

y = x + 3

In the graph, these equations are parallel

Answer:

Neither

Because the y intercepts, or the (point on the y axis) is different

Step-by-step explanation: T = 6(2d-1)

Dilation involves changing the size of a shape (i.e. a circle)

The scale of dilation is 4

The circle passes through the origin.

So, one of the points is (0,0)

When dilated it passes through the point (4,0).

The scale factor (k) is calculated by calculating the distance between the new point and the old point.

So, we have:

[tex]\mathbf{k = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}}[/tex]

This gives

[tex]\mathbf{k = \sqrt{(4- 0)^2 + (0-0)^2}}[/tex]

Simplify

[tex]\mathbf{k = \sqrt{16 +0}}[/tex]

Add 16 and 0

[tex]\mathbf{k = \sqrt{16}}[/tex]

Take the square root of 16

[tex]\mathbf{k =4}[/tex]

Hence, the scale of dilation is 4

Answer:

y = ±2i

Step-by-step explanation:

6y^2 + 24 = 0

Divide both sides by 6

y^2 + 4 = 0

Subtract 4 from both sides

y^2 = -4

Take the square root of both sides

y = ±√-4

y = ±2√-1

y = ±2i

Step-by-step explanation:

we see f(x), which is |x|.

and we see g(x), which is clearly the same basic graph, it is just shifted 3 units down in y direction.

shifts are simply done by keeping the original function definition and then add it subtract a certain constant that then adapts every original functional value.

so, a shift down by 3 units is done by adding -3.

therefore, C is the correct answer (the original f(x) - 3).

2 − 3 = −5

First we need to Add 3 to both sides of the equation:

2 − 3 + 3 = −5 + 3

Then we simplify:

2 = −5 + 3

 2 = −2

Now we divide both sides of the equation by the same term:

2 / 2 = −2 / 2

Final answer: = −1

Answer:

Y= - 1

Step-by-step explanation:

2y-3= - 5

  +3    +3

   2y= -2

   /2    /2

Y= -1

Step 1: Add 3 to both sides because you want to cancel out the 3 so you do the opposite of what is say's. For example, if it says 2y-3 add 3 or 2y+3 subtract 3 from both sides.

Step 2: Add 3 to -5 which would be -2

Step 3: Since you're "multiplying" Y to 2 you're going to divide 2 to get Y by itself. So 2/2 cancels out and now you're left with y

Step 4: Divide 2 form -2 and you get -1

Step-by-step explanation: the dude is correct

Based on the information given, the area of the triangle is 291.85.

From the information given,

A = 26

A = 26B = 27

A = 26B = 27C = 25

Firstly, we'll add the sides given and divide them by 2. This will be:

S = (26 + 27 + 25) / 2

S = 78/2

S = 39

Then we will use the formula:

= s(s - a)(s - b)(s - c)

= 39(39 - 26)(39 - 27)(39 - 25)

= 39(13 × 12 × 14)

= 85176

Lastly, we'll find the square root of the value gotten. This will be:

= ✓85176

= 291.85.

Therefore, the area is 291.85.
