What is equivalent to 9/7 ?

Answer:

Answer: D

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

Where

an = nth term

a1 = first term

r   = common difference

n  = number of the term

We are given the arithmetic sequence:

10, 12, 14, 16, ...

Where a1=10 and

r = 12 - 10 = 2

Thus the general term is:

[tex]a_n=10+(n-1)2[/tex]

Operating:

[tex]a_n=10+2n-2[/tex]

[tex]a_n=8+2n[/tex]

Answer: D

Answer:

d(n)=8+2n for n >1

Answer:

Step-by-step explanation:

Let :

x = number of Pizza's

y = number of burritos

x + y = 20 - - (1)

2.75x + 3.50y = 61 - - (2)

From (1) :

y = 20 - x

2.75x + 3.50(20 - x) = 61

2.75x + 70 - 3.50x = 61

-0.75x = 61 - 70

-0.75x = - 9

x = 9/0.75

x = 12

Answer:

Option (2)

Step-by-step explanation:

Given equation of a line → y = [tex]\frac{1}{2}x+3[/tex]

Slope of the line 'm₁' = [tex]\frac{1}{2}[/tex]

Let the equation of a line perpendicular to the given line is,

y = m₂x + b

Here, m₂ = Slope of the perpendicular line

b = y-intercept

By the property of perpendicular lines,

m₁ × m₂ = -1

Therefore, [tex]\frac{1}{2}\times m_{2}=-1[/tex]

m₂ = -2

Equation of the perpendicular line will be,

y = -2x + b

Since the perpendicular line passes through a point (-3, 4)

4 = 6 + b

b = -2

Therefore, equation of the perpendicular line wiil be,

y = -2x - 2

Option (2) will be the answer.

Answer:

4 gallons

Step-by-step explanation:

multiply 1/2 by 8 to find the number

Answer:

One gallon of paint can cover [tex]\frac{1}{4}[/tex] of a wall.

Step-by-step explanation:

start by writing the ratio:

[tex]\frac{1}{2\\}[/tex] : [tex]\frac{1}{8}[/tex]

There are two halfs in one gallon so you multiply the [tex]\frac{1}{2\\}[/tex] by 2. And whatever you do to one side must be done to the other so:

[tex]\frac{1}{2\\}[/tex]×2 : [tex]\frac{1}{8}[/tex]×2

Evaluate.

1: [tex]\frac{2}{8}[/tex]

this can be further simplified to

1: [tex]\frac{1}{4}[/tex]

Answer: 7/15

Step-by-step explanation:

1. Most probability questions are asking to find the favourable outcomes over the number of total outcomes.

The favourable outcomes will be green marbles.

There are 7 green marbles, so there are seven favourable outcomes.

There 6 + 7 + 2 = 15 total outcomes.

Thus, there are 7/15 favourable outcomes.

Answer:

x= 0.6

Step-by-step explanation:

i guess you consider this answer as a positive solution

To solve for this answer, solve the equation like so:

x/7 ≥ -6

Because you have x over 7 (meaning it is a fraction), do the opposite of the fraction (dividing), and multiply

x/7 ≥ -6

x7    x7

x ≥  -42

Answer:

1/6

Step-by-step explanation:

2/9 x 3/4

if you multiply together, it would be 6/36, if you simplify, it would be 1/6

Answer:

1/6

Step-by-step explanation:

You multiply fractions straight across. This means numerator to numerator and denominator to denominator.

2 x 3 = 6

9 x 4 = 36

So, it will be 6/36. Now you simplify by dividing by the greatest common factor (GCF). Both can be divided by six.

6/6 = 1

36/6= 6

The final answer is 1/6

Answer:

yes, it is a right triangle and ∡Q is the right angle

Step-by-step explanation:

if the slope of QR is the opposite reciprocal of QS then the two segments are perpendicular and form a 90° angle

slope of QR:  -3 - (-1) ÷ 2 - 0  = -2 ÷ 2 = -1

slope of QS:  -3 - (-1) ÷ 2 - 4  = -2 ÷ -2 = 1

-1 and 1 are opposite and reciprocal so m∡Q = 90°

Answer:

[tex]\frac{1}{10}[/tex]

Step-by-step explanation:

note that in terms of the given fraction

1 = [tex]\frac{10}{10}[/tex] , then

[tex]\frac{9}{10}[/tex] + [tex]\frac{1}{10}[/tex] = [tex]\frac{10}{10}[/tex] = 1

Answer:

[tex] \frac{9}{10} + x = 1 \\ x = 1 - \frac{9}{10} \\ x = \frac{(10 - 9)}{10} \\ \boxed{x = \frac{1}{10} } \: is \: the \: required \: number[/tex]

Answer:

x = 37

Step-by-step explanation:

Use the theorem formula

a^2+b^2=c^2

35^2 + 12^2 = c^2

1225 + 144 = c^2

1369 = c^2

divide by square root

c = 37

so x = 37

Answer:

Since it’s negative it will have a negative slope so it would be down to a, b, c

Then look at the y intercept which is 2 and it’s positive so it would be c
