1) 2/5= 0.4

2) 2 1/8= 2.1

3) 4/33= 0.12

4) -6/11= -0.54

Explanation:

In fractions, the numerator is the number above the line and the denominator is the number below.

The line in a fraction that separates the numerator and the denominator represents division.

To convert a fraction to a decimal, divide the numerator by the denominator.

The given lines n: y = -2x-4 and line m: y = -2x+8 are neither parallel nor perpendicular

The slope of the parallel line is 0 and the slope of the perpendicular line is undefined.

The lines are parallel if their slopes are the same but their y-intercepts differ. The lines are not parallel if the slopes differ. Perpendicular lines, unlike parallel lines, do intersect. Their intersection creates a 90-degree angle.

Here given line ,

y = -2x - 4

= y = 2x + 4

Since this is in mx + b form ,

m is the slope

So slope = 2.

Given another line = -2x + 8

Slope = -2

Since slopes are not equal they are not parallel .

Since slopes are not negative reciprocal they are not perpendicular .

Answer:

The conclusion of the conditional statement is;

it is an integer and a prime number

Step-by-step explanation:

The statement that the argument claims to be true or the statement that the rest of a conditional statement leads to is the conclusion of a conditional statement

Given a conditional statement, also known as an if-then statement, which can be represented symbolically as p → q, such that the hypothesis is p and the conclusion is q.

In the given statement, the hypothesis, p = a number is odd, while the conclusion, q =  it is an integer and a prime number

Therefore, the conclusion of the conditional statement is it is an integer and a prime number.

However, only the converse of the statement is true, which is given as follows;

If a number is an integer and a prime number, then it is an odd number

Answer: 210

Step-by-step explanation:

We know that the number of combinations of n things taken r at a time is given by :-

[tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]

So, number of ways to select 3 plants out of 7 = [tex]C(7,3)=\dfrac{7!}{3!4!}=\dfrac{7\times6\times5\times4!}{6\times 4!}=7\times5=35[/tex]

Also number of ways to arrange them in 3 positions = 3! = 6

Now , total number of arrangements with 1 plant in each spot = (number of ways to select 3 plants out of 7) x (number of ways to arrange them in 3 positions)

= 35 x 6

=210

Hence, required number of ways = 210

Since, the arrangement does not matter, we use the principle of combination, Hence, the number of display arrangement possible is 210

This could be defined thus as : (7C3) × 3! ;

3! = number of ways to arrange the 3 plants into the 3 spots

Recall :

7C3 = [tex] \frac{7!}{(7-3)!3!} = \frac{7!}{4!r3!} [/tex]

7C3 = [tex] \frac{7×6×5}{6} = 35 [/tex]

3! = 3 × 2 × 1 = 6

(7C3) × 3! = 35 × 6 = 210 ways

Therefore, there are 210 possible arrangements which can be made.

Answer:

28°

Step-by-step explanation:

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

m∠TUV = m∠TUQ + m∠QUV

m∠TUQ = 5*7° - 7° = 28°

x + 21 + 3x + 9 = 90

Combine like terms

4x + 30 = 90

Subtract 30 from both sides

4x = 60

Divide both sides by 4

x = 15

Answer:

x = 15

Step-by-step explanation:

You can use the opposite angles property to solve this problem. By using the property, the opposite angle of x+21 must also be x+21. So therefore, you can setup the equation x+21+3x+9=90. Simplify and you should get 4x+30=90. Subtract 30 on both sides and you get 4x=60. Divide 4 on both sides and you get x=15.

Answer:

x = - 2

Step-by-step explanation:

Given

- x - 4 + 3x = - 5x - 18 , that is

2x - 4 = - 5x - 18 ( add 5x to both sides )

7x - 4 = - 18 ( add 4 to both sides )

7x = - 14 ( divide both sides by 7 )

x = - 2

Step-by-step explanation:

(7/8) / (6/9)

= (7/8) / (2/3)

= (7/8) * (3/2)

= (7 * 3) / (8 * 2)

= 21/16.

The result is: 7/8 divided by 6/9 is equal to 21/16.

To divide one fraction by another, we can multiply the first fraction by the reciprocal (inverse) of the second fraction.

The reciprocal of a fraction is obtained by flipping it upside down.

we have to find 7/8 divided by 6/9:

now we find the reciprocal of 6/9.

Reciprocal of 6/9 = 9/6 (Flip the fraction upside down)

Multiply 7/8 by the reciprocal of 6/9.

(7/8) × (9/6)

To simplify the fraction, first, check if both the numerator and denominator share any common factors and then divide both by their greatest common divisor (GCD).

Now, let's calculate:

(7/8) × (9/6)

Multiply the numerators: 7 × 9 = 63

Multiply the denominators: 8 × 6 = 48

The result is 63/48.

Find the greatest common divisor (GCD) of the numerator and denominator, which is 3 in this case (GCD of 63 and 48).

Divide both the numerator and denominator by the GCD (3):

63 ÷ 3 = 21

48 ÷ 3 = 16

The simplified fraction is 21/16.

So, 7/8 divided by 6/9 is equal to 21/16.

Answer:

B. 4 tablespoons

Step-by-step explanation:

Let’s make a proportion using the following setup:

tablespoons/servings=tablespoons/servings

We know that 12 tablespoons are needed for 60 servings.

12/60=tablespoons/servings

We don’t know how many tablespoons are needed for 20 servings. We can say x tablespoons make 20 servings.

12/60=x/20

Want want to solve for x, so we must isolate x. x is being divided by 20. The inverse of division is multiplication. Multiply both sides of the proportion by 20.

20*(12/60)=(x/20)*20

20*12/60=x

20*0.2=x

4=x

x= 4 tablespoons

4 tablespoons of butter are used to make 20 servings.

Answer: [tex]\overline{VW}=15[/tex] units.

Step-by-step explanation:

Since Point W is on line segment [tex]\overline{VX}[/tex].

That means V,W,X  are collinear such that [tex]\overline{VX} = \overline{WX}+\overline{VW}[/tex]  (i)

Given[tex]\overline{ WX}=2[/tex] units. ,  [tex]\overline{ VX} = 17[/tex] units.

To determine :  length of [tex]\overline{ VW}[/tex].

Substitute all the given values in (i), we get

[tex]17=2+\overline{VW}\\\\\Rightarrow\ \overline{VW} =17-2=15\\\\\Rightarrow\overline{VW}=15[/tex]

Hence, the length of [tex]\overline{VW}=15[/tex] units.
