Harvey is reading a map of the Rocky Mountains. The map is drawn to scale so that 1.1 inches represents
88 miles. How many miles does 1.3 inches represent?

Step-by-step explanation:

A playing card is in the form of a rectangle whose perimeter is equal to 28 cm and area is 45 cm².

If l and b are length and breadth of the rectangle.

Area,

[tex]A=lb[/tex]

[tex]45=lb\\\\l=\dfrac{45}{b}\ .....(1)[/tex]

Perimeter,

[tex]P=2(l+b)\\\\28=2(l+b)\\\\14=(l+b)\ ....(2)[/tex]

Put the value of l from equation (1) to equation (2). So,

[tex]14=\dfrac{45}{b}+b\\\\14=\dfrac{45+b^2}{b}\\\\14b=45+b^2\\\\b^2-14b+45=0\\\\b^2-9b-5b+45=0\\\\b(b-9)-5(b-9)=0\\\\b=5\ cm, 9\ cm[/tex]

Put the value of b in equation (1),

If b = 5 cm

[tex]l=\dfrac{45}{5}=9\ cm[/tex]

If b = 9 cm

[tex]l=\dfrac{45}{9}=5\ cm[/tex]

So, the dimensions of the playing card is 9 cm by 5 cm.

Answer:

the total length of his drive is 42

Answer:

0.57

Step-by-step explanation:

Step 1: Count the total amount of squares

10 by 10 square, so 100 squares in total

Step 2: Count how many rows have been filled

5 rows of 10, so 50 out of 100, or 0.50

Step 3: Count the rest

7 out of 100, so 0.07

Step 4: Add

0.07 + 0.50 = 0.57

Answer:

0.57

Answer:

t = 13.2 s

Step-by-step explanation:

Given that,

An athlete ran the 100 meter sprint in 13.245 seconds. We need to round off the time to the nearest tenth.

Here, t = 13.245 s

In order to round off to the nearest tenth, thousandths place and hundredth place gets eliminated.

So, t = 13.2 s

So, time is 13.2 seconds.

Answer: 13.2

Step-by-step explanation:

The answer would be: x=9

(Below is how I got ‘x=9’)

Here are the steps to solve this problem/equation.

1. Simplify both sides to the equation.

⇒10x +-21=61

⇒10x -29=61

2. Now add 29 to both of the sides

⇒ (you will end up with: 10x=90

3. And finally you divide both sides by 10

⇒ so x=9

Answer:

154

Step-by-step explanation:

To find the percentage, we can set up a percentage proportion, where x is 7% of 2200.

[tex]\frac{x}{2200} = \frac{7}{100}[/tex].

Now we can cross multiply to find the value of x.

Answer:

2x^3 - 10x^2 +12x

Step-by-step explanation:

p(x)= 2x^2 -4x

q(x) = x-3

(p•q)(x) = (2x^2 -4x) * ( x-3)

        FOIL

first 2x^2 *x = 2x^3

outer  2x^2 *-3 = -6x^2

inner -4x *x = -4x^2

last  -4x*-3 = 12x

Add together

2x^3 -6x^2 -4x^2 +12x

Combine like terms

2x^3 - 10x^2 +12x

Answer:

Step-by-step explanation:

p(x) =2x² - 4x

q(x) = x - 3

In order to find (p•q)(x) substitute q(x) into p(x) that's replace every x in p(x) by q(x)

That's

(p•q)(x) = 2( x - 3)² - 4( x - 3)

Expand the terms

That's

(p•q)(x) = 2( x² - 6x + 9) - 4x + 12

= 2x² - 12x + 18 - 4x + 12

Group like terms

(p•q)(x) = 2x² - 12x - 4x + 18 + 12

Simplify

We have the final answer as

(p•q)(x) = 2x² - 16x + 30

-9x6n=-54

-9x-4= -54n

-72-54n+36

-72+36=-36

-54n-36

Answer

So changing 1/4 by multiplying top and bottom by 9 gives 9/36 and changing 2/9 by multiplying top and bottom by 4/4 gives 8/36 and adding 9/36 to 8/36 gives 17/36 - a rational number.

Answer: The answer is: it is a fifth degree binomial or 'quintic binomial'.

Step-by-step explanation:

Is the expression 3x^2-5x^3 a polynomial?

So, we have to know what polynomial means. A polynomial is... "an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables."

So let's take a look at this expression.

Does it consist of variables and coefficients? YES

Does it only involve operations of addition, subtraction, multiplication, and non-negative integer exponents of variables? YES

Therefore, it is a polynomial.

Now, we have to figure out what degree this polynomial is.

The degree of the polynomial is the degree of the monomial with the largest degree.

So the largest degree would be the 3rd degree, because it is, of course, the largest out of the two powers listed.

And also, keep in mind that this is a binomial (made up of two monomials).

Therefore, it is a fifth degree binomial or 'quintic binomial'.

Answer:

The first thing you need to do here is create an equation.

I've created it for you: 6x = 8x - 4

If you want to solve it, you have to move the like terms to one side so...

4 = 2x

and x = 2

Answer:

the height of the candle before it is lit

Step-by-step explanation:

When the candle is first lit, time is 0.

At tome 0, x = 0 and the height is -0.25(0) + 5 = 5.

The height is 0 at time zero, so the constant term, 5, represents the height of the candle before it is lit.

The answer is

2^6(1-3n)×2^4(3n-3)=2^6(-3n-3).

2^(6-18n)×2^(12n-12)=2^(-18n-18).

(6-18n)×(12n-12)=(-18n-18).

6-18n×12n-12=18n-18.

6-12×-18n-12n=18n-18

-6×-30n=18n-18.

-6×18=-18+30

-108=48n.

n= -108/48.

n=-2.25.

Answer: Supplementary, 3 and 2, substitution, 2.

Step-by-step explanation: just did it .

The ∠1 is congruent to ∠3 by definition of congruency.

An angle is formed from the intersection of two lines. Types of angles are acute, obtuse and scalene.

m∠1 + m∠2 = 180°  (given)

m∠2 + m∠3 = 180°  (given)

Hence:

m∠1 + m∠2  = m∠2 + m∠3  (equality property)

Subtract m∠2 from both sides to get:

m∠1  = m∠3

Answer:

1.5

Step-by-step explanation:

First find 1 3/4 and 1 1/6 as an improper fraction. 1 3/4 = 7/4 because 1 times 4 plus three. 1 1/6 = 7/6 because 1 times 6 plus 1, so now you have 7/4 divided by 7/6. You change 7/6 to it's reciprocal, which is 6/7. Now it's like multiplication with fractions. 7*6=42. 4*7=28, so it's 42/28.

Now we want to simplify. It can be simplified to 1 1/2, which is also 1.5. Hope this helps.

Answer:

8

Step-by-step explanation:

10 + 8 = 18

18 x 2 = 36

Answer:

So we know the sum of two numbers, let them be x and y, is equal to 36:

x + y = 36

And on of them, for example, y, is equal to 10:

x + 10 = 36

Now, the only thing we need to do is solving the equation to find x:

x + 10 = 36

We pass the 10 substracting to the right:

x = 36 - 10

And now, we substract:

x = 26

Now we know one number is 10 and the other is 26, so we can verify we have done all correctly

26 + 10 = 36 (TRUE)

Now we know we have done the exercise well.
