Answer:

See answers below

Step-by-step explanation:

Given the following ratios. We are to express them in their simplest forms

15:12

= 15/12

= (3*5)/(3*4)

= 3/3 * 5/4

= 5/4

b) 42:1

= 42/1

= 42

Given that  2:x :: 4:6​

2/x = 4/6

Cross multiply

4x = 2*6

4x = 12

x = 12/4

x = 3

Hence the value of x is 3

Answer:

1. All real numbers

2. All real numbers

3.x>=0

4.y>=-6

Step-by-step explanation:

The domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a functions g(x) and k(x)

g(x) = x - 6

The domain of the function:

D: x ∈ (-∞, ∞) or

All real numbers.

k(x) = √x

The domain of the function k(x) is x ≥ 0

The range of the function k(x) is y ≥ 0

The sum of the functions:

= g(x) + k(x)

= x - 6 + √x

= x + √x - 6

The domain of the function is x ≥ 0

The range of the function is y ≥ -6

Thus, the domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.

Answer:

3.605 ft is the answer.

Step-by-step explanation:

Applying Pythagoras theorem,

a^2 + b^2 = c^2

2^2 + 3^2 = c^2

4 + 9 = c^2

13 = c^2

3.605 = c

therefore, the answer is 3.605.

Answer:

6. 141

7. 28

Step-by-step explanation:

Time to rewrite the expressions!

6. (8 + 45/9)² - 14(2)

First, we need to solve what's in the parentheses.

45/9 is 5. So 8 + 5 is 13. 13² - 14(2)

Now, the exponent. 13² = 169 (nice)

169 - 14(2) Multiply 14 and 2...

169 - 28 = 141

Now to rewrite 7.

12 + 36/2 - 3(1)²

Exponents first...

3² = 9 (the 1 isn't included 'cause 3 multiplied by 1 is still 3.)

12 + 36/2 - 12

Divide... 36/2 = 18

12 + 18 - 2

30 - 2

28

Answer:

Step-by-step explanation:

Distributive property can be defined as :

a(b+c)= (a*b) + (a*c)                            

So, the given expression 3xy+6yz can be written as :                                    

1st way :                                          

= 3xy+6yz

2nd way :                

= 3xy+6yz    

On Monday Mark ran for a distance of  [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of  [tex]\frac{106}{15}[/tex] miles.

What is a fraction ?

A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.

It is given that on Monday , Mark ran [tex]1\frac{1}{3}[/tex] miles to school and then [tex]2\frac{1}{5}[/tex] miles to his grandmother's house.

This meant the total distance he ran on Monday can be calculated by adding both the distances he travelled on the particular day i.e.,

=  [tex]1\frac{1}{3}[/tex] miles + [tex]2\frac{1}{5}[/tex] miles

= [tex]\frac{4}{3}[/tex] miles + [tex]\frac{11}{5}[/tex] miles

Now , to add two fractions we need to equal denominator.

= [tex]\frac{20+33}{15}[/tex]

= [tex]\frac{53}{15}[/tex] miles

Now , on Tuesday he ran twice as much as Monday. So , the distance he ran on Tuesday is equal to :

= 2 × [tex]\frac{53}{15}[/tex] miles

= [tex]\frac{106}{15}[/tex] miles

Therefore , on Monday Mark ran for a distance of  [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of  [tex]\frac{106}{15}[/tex] miles.

Answer: The initial elevation of the plane was 8.75 miles.

Step-by-step explanation:

Suppose that the initial elevation of the plane is E.

Then the plane descends 3.5 miles.

Then the new elevation of the plane will be:

E - 3.5 miles.

Now, we know that the new elevation of the plane is 5.25 miles, then:

E - 3.5 miles = 5.25 miles.

Now we need to solve this for E.

To solve this, we can add the same number to both sides of the equation, so we can add 3.5 miles to both sides to get:

(E - 3.5 miles) + 3.5 miles = 5.25 miles + 3.5 miles

E + (3.5 miles - 3.5 miles) = 5.25 miles + 3.5 miles

E = 8.75 miles.

The initial elevation of the plane was 8.75 miles.

Answer:

39.12

Step-by-step explanation:

One of the properties of a rectangle is that every angle in it is congruent. This means that when a diagonal is drawn (a segment connecting opposite corners), a right triangle is formed. One can apply the Pythagorean theorem, this theorem states the following;

[tex]a^2 + b^2 = c^2[/tex],

Where (a) and (b) are the legs, or segments adjacent (next to) the right angle, and (c) is the hypotenuse (the side opposite the right angle).

The legs of the right triangle formed by the diagonal in a rectangle will be the sides of the rectangle. Using this knowledge, one can state the following,

[tex]a^2 = b^2 = c^2\\\\21^2 + 33^2 = c^2[/tex]

Simplify,

[tex]441 + 1089 = c^2\\\\1530 = c^2[/tex]

Inverse operations,

[tex]1530 = c^2\\\\39.1152=c[/tex]

Answer:

5(2m+3)-4m is 3 less than 5(2m+3)-4m

Step-by-step explanation:

How does 5(2m+3)-4mcompare to 5(2m+3)-4m when m is a postive intenger .

Expand 2(3m+6) and 5(2m+3)-4m

For 2(3m+6)

= 2(3m)+2(6)

= 6m+12

For 5(2m+3)-4m

= 5(2m)+5(3)-4m

= 10m+15-4m

= 10m-4m+15

= 6m+15

Take their difference

6m+15 -(6m+12)

=6m-6m+15-12

= 3

Hence 5(2m+3)-4m is 3 less than 5(2m+3)-4m

Answer:

3( -8 + 1) = 3( -8) + 3(1)

Step-by-step explanation:

That is distributive property

Answer:

3(-8+1)=(3(-8)+(3(1)

Step-by-step explanation:

In this case, distributive property is when a number or you could call it integer, multiplies with another set of number inside parentheses ().

Your answer was wrong, because 6 x 7=42, and that's not equal to the other side of numbers.

The top one is addition, so that's a no.

The second one's not exactly in the form you want it to be for it to be the same as the left side.

The third one shows distributive property in two ways, which give you the same result, so that would be the correct answer.
