Answer:

[tex]48m^2-72mn[/tex]

Step-by-step explanation:

We need to solve [tex](8m-3n)^2 - (4m+3n)^2[/tex]

We know that,

[tex](a+b)^2=a^2+b^2+2ab\\\\(a-b)^2=a^2+b^2-2ab[/tex]

Using the above formula,

[tex](8m-3n)^2 - (4m+3n)^2=(8m)^2+(3n)^2-2(8m)(3n)-[(4m)^2+(3n)^2+2(4m)(3n)]\\\\=64m^2+9n^2-48mn-(16m^2+9n^2+24mn)\\\\=64m^2+9n^2-48mn-16m^2-9n^2-24mn\\\\=48m^2-48mn-24mn\\\\=48m^2-72mn[/tex]

So, the final answer is [tex]48m^2-72mn[/tex].

Answer:

$637.50

Step-by-step explanation:

P = $3000

t= 5years

r = 4.25% per annum

Interest = (p×r×t)/100

= (3000×4.25×5)/100

= $637.50

Answer: To do that you divide the top to the bottom so 4,102 divided by 7 which is 586

Answer: 586

Step-by-step explanation:

The decimal notation is 586.0

A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.

Given:  4,102/7

Now to write the above fraction into decimal we have to divide the fraction

as

4102/7= 586

As, the divides the fractions completely.

Hence, the decimal notation is 586.0

Answer:

5 hours

Step-by-step explanation:

737mi / 11hr = 67mph

335mi / 67mph = 5hr

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

Here are two ways to solve

Method 1

First determine her speed if she goes 737 miles in 11 hours.

distance = rate*time

d = r*t

737 = r*11

737 = 11r

11r = 737

r = 737/11

r = 67

Her speed is 67 mph. Use this to find how long it would take if she drove 335 miles.

d = r*t

d/r = t

t = d/r

t = 335/67

t = 5 hours is the time it takes to drive 335 miles assuming Martina drives at the same speed.

---------------------------------------------------------------------

Method 2

We can use a proportion to solve

(distance 1)/(time 1) = (distance 2)/(time 2)

(737 miles)/(11 hours) = (335 miles)/(x hours)

737/11 = 335/x

737*x = 335*11 .... cross multiply

737x = 3685

x = 3685/737 ..... divide both sides by 737

x = 5

We get the same answer of 5 hours.

Answer:

7

Step-by-step explanation:

hey there,

< Here's how you do subtraction in fractions!

Make sure you find a least common denominator. Here, it's given to you to be 15. Usually, you can just multiply the two denominators but then it would be quite large at times, so you kind of just have to guess.

How did they go from  [tex]\frac{4}{5} x-\frac{1}{3} x[/tex]  to [tex]\frac{?}{15} x[/tex]?

Well, they used a least common denominator. 5 was multiplied by 3 to create 15, and 3 was multiplied by 5. But when you multiply the bottoms, you have to multiply the tops of the fraction too (the numerators).

So 4/5x was multiplied by 3. Denominator turned out to be 15, and now the top is 4x3 = 12. So the fraction is 12/15.

1/3x, on the other hand, was multiplied by 5. Denominator was also 15 so they're the same, and top is 1x5 = 5. So the fraction is 5/15.

Now, let's put them together.

[tex]\frac{12}{15}x-\frac{5}{15} x[/tex]

When subtracting x, the x just stays there, so if it was 10x-4x, the answer would've been 6x. So now let's subtract!

12-5 = 7, and the denominator stays the same.

The answer is [tex]\frac{7}{15} x[/tex]. So the numerator, or answer to your question, would be 7.

Answer: 2.204

Step-by-step explanation:

Answer:

Length = 12

Step-by-step explanation:

L × W = Area

84 / 7 = 12

12 × 7 = 84

The required length of the given rectangular garden is given as 12 feet.

Given that,
A rectangular garden has an area of 84 square feet. If the width of the park is 7 feet, what is length is to be determined.

The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.

here,
Let the measure of the length of the rectangular garden be l,
Since,
Area of the rectangle  = length × width

Area of the rectangle = l × 7
l × 7 = 84
l = 84 / 7
l = 12 feet

Thus, the required length of the given rectangular garden is given as 12 feet.

Answer:

  1.5 cm

Step-by-step explanation:

The midpoint of OB is 9/2 = 4.5 cm from O

The midpoint of OA is 12/2 = 6.0 cm from O

Since O is not on AB, we must have B on OA, so the distance between midpoints is ...

  6 cm -4.5 cm = 1.5 cm . . . . distance between midpoints

Answer:

Step-Smallest angle = 40

by-step explanation:

Angle sum property:Sum of all three angles of triangle is 180

2x - 6 + 3x + 5 + 2x + 20 = 180   {Combine like terms}

2x + 3x + 2x - 6 + 5 + 20 = 180

                     7x  + 19       = 180            {Subtract 19 from both sides}

                                      7x = 180 - 19

                                      7x = 161               {Divide both sides by 7}

                                         x = 161/7

x = 23

2x - 6 = 2*23 - 6 = 46 - 6 = 40

3x + 5 = 3*23 + 5 = 69 + 5 = 74

2x + 20 = 2*23 + 20 = 46 + 20 = 66

Answer:

4 to 3

Step-by-step explanation:

Colton wrote a ratio comparing the number of sports video games that he owns to the number of driving video games that he owns as 4:3. Which ratio is equivalent to Colton’s ratio?

Three-sevenths

Four-sevenths

3 to 4

4 to 3

Ratio of the number of sports video games that he owns to the number of driving video games that he owns = 4 : 3

number of sports video games that he owns : number of driving video games that he owns = 4 : 3

4 : 3 = 4 / 3

Three-sevenths = 3 / 7

Four-sevenths = 4 / 7

3 to 4 = 3 / 4

4 to 3 = 4 / 3

The equivalent ratio to Colton’s ratio is 4 to 3
