A boat travels 39 miles in 4 hours and 20 minutes. What is the speed of the boat in miles per hour?

Answers

Answer 1

Answer:

Answer:

9.01 miles in 1 hour

Step-by-step explanation:

to get the answer first u need to do is turn the 20 mins to hours

well we can also turn the hour to mins and then turn it into hours

260 mins= 4.33 hours (rounded)

then 39/4.33= x/1

divided the top and bottom by 4.33

9.01/4.33 (rounded)

Pls help What is true about the following sequence: 2.7, 6.5, 10.3, 14.1, 17.9*A. It has a common ratio of approximately 2.4
B. It is neither a geometric nor an arithmetic sequence
C. It has a common difference of -3.8
D. It has a common difference of 3.8

Answers

Answer:

D.) It has a common difference of 3.8

Step-by-step explanation:

When you subtract $a_(2) -a_(1)$ you get a common difference, the same goes for the other values: when you subtract the previous term from the next, you get a common difference of positive 3.8

To determine the area of a rectangle, one strategy is to split the rectangle into smaller pieces, and determine the smaller areas first. Explain how this strategy relates to binomial multiplication.

Answers

Area of the rectangle is determined by Binomial Multiplication as given below.

What is Binomial Multiplication ?

Binomial Multiplication follows FOIL method , Firsts , Outer terms , Inner Terms , Last Terms.

A rectangle is given and area of the rectangle has to be determined by splitting it into smaller rectangles.

Let the rectangle is of 5*3 ft

To determine the area the rectangle has been split into rectangles of 15 rectangles as seen in the figure attached.

Area of the smaller rectangle is given by Length * Breadth = 1*1

Let us consider x = 1

Then

The side of the rectangle will be ( x+4) ( x+2)

On solving this by FOIL

x² + 6x +8

Area = x² + 6x +8

Area = 1 + 6 + 8 = 15 sq.ft

Area of the bigger rectangle =

= ( Area of 1st rectangle + Area of 2nd Rectangle + ...... + Area of 15th Rectangle)

= 15 * ( Area of the smaller rectangle)

Area of the bigger rectangle = 15 * ( 1 * 1)

Say you have a big rectangle. You can split that big rectangle up into little rectangles, say unit rectangles whose areas are 1, and then count up all those little rectangles to find the area of the larger rectangle. So for instance:
I have a rectangle that has an area of 4ft^2
I can split up that rectangle to smaller rectangles of 1ft^2
Then I can count how many smaller rectangles I have and deduce the area of the larger rectangle form that -> 1ft^2 * 4 = 4ft^2

What is the solution to the system of equations graphed below? y = x - 2 y = 4x - 5

Answers

There are 3 available methods - Substitution , Elimination and Matrix.

The substitution method is used to eliminate one of the variables by replacement.

The elimination method is used for solving linear systems.

A Matrix is an array of numbers.

Lets use Substitution to solve this system.

$x-2=4x-5$

$-2=4x-5-x$

$-2=(4x-x)-5$

$-2=3x-5$

$-2+5=3x$

$3=3x$

$3=3x / 3$

$x=1$

Now substitute $x=1$

$y=x-2$

$y=1-2$

$y=-1$

Hence - $x=1 y=-1$
