i am not a natural number

i am less than -13

what number am i?

Answers

Answer:Any number less than -13.

Step-by-step explanation:

If the number is real and rational and non-natural, this means that it can be any number in the negative number space.

Additionally, since the number has to be less than -13, then the number could be any number less than -13.

With all these things considered, the number is any number less than -13 that is real and rational.

Henry needs 2 pints of red paint and 3 pints of yellow paint to get a specific shade of orange. If he uses 9 pints of yellow paint and wants the same orange color, how many pints of paint will he need altogether? Explain how you know.

Answers

3 yellow - 2 red
9 yellow - ? red
3 * 3 - 2 * 3
He needs 6 red

Answer:

Henry will need a total of 15 pints of paint. The 3 pints of yellow were multiplied by 3 to get 9 total, so 2 pints of red would be multiplied by 3 to get 6 total.

Line segment EG is partitioned by point F in the ratio 1:2. Point E is at E (0, 4), and point F is at (1, 3). What are the coordinates of point G?

(−1, 5)
(2, 2)
(3, 1)
(4, 0)

Answers

Answer:

(3, 1)

Step-by-step explanation:

The coordinates of point G is (c) (3,1)

The coordinate points are given as:

[tex]\mathbf{E = (0,4)}[/tex]

[tex]\mathbf{F = (1,3)}[/tex]

The ratio is given as:

[tex]\mathbf{m : n = 1 :2}[/tex]

Line ratio is given as:

[tex]\mathbf{(x,y) = \frac{mx_2 + nx_1}{m + n}, \frac{my_2 + ny_1}{m + n}}[/tex]

Point F is at the partitioned point.

So, we have:

[tex]\mathbf{(1,3) = \frac{1 \times x_2 + 2 \times 0}{1 + 2}, \frac{1 \times y_2 + 2 \times 4}{1 + 2}}[/tex]

[tex]\mathbf{(1,3) = \frac{x_2 }{3}, \frac{y_2 + 8}{3}}[/tex]

Multiply through by 3

[tex]\mathbf{(3,9) = (x_2, y_2 + 8)}[/tex]

By comparison, we have:

[tex]\mathbf{x_2 = 3}[/tex]

[tex]\mathbf{y_2 + 8= 9}[/tex]

Subtract 8 from both sides

[tex]\mathbf{y_2 = 1}[/tex]

Hence, the coordinates of point G is (c) (3,1)

Step-by-step explanation:

Answer:

A. 0.318 and 0.3444...

Step-by-step explanation:

Rational numbers are numbers that can be expressed as fractions. Rational numbers include finite values and repeating decimals that have a pattern.

Because all of the answer choices include decimals that have no predictable pattern of decimals, A must be correct.

0.318 is rational because it is finite. 0.3444... will continue to add 4 on to the end of the number, meaning it is repeating predictably, and it is rational.

A new shopping mall is gaining in popularity. Every day since it opened, the number of shoppers is 20% more than the number of shoppers the day before. The total number of shoppers over the first 4 days is 671

Answers

Answer:

First term = a = 125

Step-by-step explanation:

Question: find the number of shoppers on the first day

This is a geometric progression question

The sum of the terms = 671

Sum of a geometric sequence,Sn = (ar^n - 1) / (r - 1)

Where,

n = number of term in the sequence.

a = first term in the sequence.

r = common ratio

r = 1 + 20%

= 1 + 20/100

= 1 + 0.2

= 1.2

n = 4 (first 4 days)

Sn = (ar^n - 1) / (r - 1)

Sn = 671 where n = 4

671 = {a × 1.2^(4) - 1} / 1.2 - 1

671 = {a × 2.0736 - 1} / 0.2

671 = (2.0736a - a) / 0.2

671 = 1.0736a / 0.2

671 = 5.368a

Divide both sides by 5.368

a = 671 / 5.368

a = 125

Gavin plays a soccer video game. He earns 2 stars for every goal he scores and loses 1/2 star every time he misses the goal. He scores 7 goals and misses the goal 6 times.
how many stars does he have?

Answers

Answer:

Step-by-step explanation:

If he scored 7 goals with each goal being worth 2 stars, that's 14 stars. If he missed 6 times, then he lost 3 stars. So the answer is 11.

11 because 7*2=14 and 6/3=2 so 14-2=11 and that’s you answer

Write an equation for a line parallel to
y = 3x - 1 and contains the point (-2, 8).

Answers

Answer:

y=3x+14

Step-by-step explanation:

Answer:

y = 3x + 14

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 1 ← is in slop- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation

To find c substitute (- 2, 8) into the partial equation

8 = - 6 + c ⇒ c = 8 + 6 = 14

y = 3x + 14 ← equation of parallel line

what is the area of a rectangle 2m long and 40cm wide

Answers

Answer:

8000 cm^2 or 8 m^2

Step-by-step explanation:

We can convert 2 meters to centimeters, simply by multiplying the ,meters value by 100. So, the converted dimensions of the rectangle are 200 cm by 40 cm. Multiplying to get the area, we have 8000 cm^2. This could also be expressed in terms of m^2 as 8 m^2.

24,29,32 determine whether the triangle is obtuse, right, acute, or not a triangle

Answers

Answer:

When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:

1) Square all 3 sides.

24^2= 576

29^2= 841

32^2= 1,024

2) Sum the squares of the 2 shortest sides.

576 + 841 = 1,417

3) Compare this sum to the square of the 3rd side.

if sum > 3rd side² Acute Triangle

It's an acute triangle.

if sum = 3rd side² Right Triangle

if sum < 3rd side² Obtuse Triangle
