Answer:

-1

Step-by-step explanation:

Any number less than -2 (ex -3, -4, -5) are less than -2

Answer:

-1

Step-by-step explanation:

If you look at a number line, you will see that -1 comes before -2. Since -2 is a negative number, then the lower the number, the greater it is.

Answer:

Step-by-step explanation:

π/2 < 4π/5 < π

4π/5 is in Quadrant II

sin(4π/5) = y-coordinate of A

The coordinates is equal to sin(4π/5) = y-coordinate of A.

We need to find the coordinates is equal to sin (4pi/5).

In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.

In second quadrant(π/2 < θ < π), only sin and cosec are positive.

In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.

In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.

Then, we have π/2 < 4π/5 < π

So, 4π/5 is in Quadrant II

Hence,  the coordinates is equal to sin(4π/5) = y-coordinate of A.

20×22×2= 880m cube

Answer:

a= 38°

b=52°

c=40°

Step-by-step explanation:

hope it helped:)))))))))))))))))))

Answer:

For the first group we have the pairs:

year           population

0                20

1                 80

2                320

3                 1,280

4                 5,120

5                 20,480

Here we can see that the population quadruples each year

(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)

then the population equation is:

P(0) = 20

P(1) = 20*4

P(2) = (20*4)*4 = 20*4^2

We already can see the pattern, then we can write this relationship as:

P(t) = A*(4)^(t)

Where:

t represents time in years, and A is the initial population, that we know it is 20, then:

P(t) = 20*(4)^t

This is the function that represents the table.

B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:

Q(t) = 20*(3)^t

C) Now, if the initial population of the second group is 40, the equation becomes:

Q(t) = 40*(3)^t

The population by year 3 is given by replacing t by 3, then:

Q(3) = 40*(3)^3 = 1080

And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:

1,280 - 1,080 = 200

So the first group is larger by 200 squirrels.

Answer:

24°

Step-by-step explanation:

[tex]r \degree = 180 \degree - (34 + 122) \degree \\(vertical \: \angle s) \\ \\ r \degree = 180 \degree - 156 \degree \\ \\ r \degree = 24 \degree \\ \\ r = 24[/tex]

Answer and Step-by-step explanation:

The answer is 24 degrees.

We see the angle 34 and 122. To find that angle in between, we subtract those numbers from 180.

180 - 34 - 122 = 24 = r

By the vertical angles theorem, r is equal to 24.

Answer:

Yes, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.

Step-by-step explanation:

For the given vessel without a lid,

diameter = 0.4 x 1.5

               = 0.6 m

radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{0.6}{2}[/tex]

           = 0.3 m

Total external surface area of the vessel = 2[tex]\pi[/tex]rh + [tex]\pi[/tex][tex]r^{2}[/tex]

                             = [2 x [tex]\frac{22}{7}[/tex] x 0.3 x 1.5] + [[tex]\frac{22}{7}[/tex] x [tex](0.3)^{2}[/tex]]

                             = 2.8286 + 0.2829

                             = 3.1112

Total external surface area of the vessel is 3.1112 square meter.

Total internal and external surface area = 2 x 3.1112

                                                              = 6.2224 [tex]m^{2}[/tex]

But for 1 square meter, 150 g of paint is consumed. Thus;

for 6.2224 [tex]m^{2}[/tex] = 6.2224 x 150 g

                       = 933.36 g

Thus, 6.2224 [tex]m^{2}[/tex] of area would require 933.36 g of paint.

So that,

[tex]\frac{933.36}{1000}[/tex] = 0.93336 kg

Therefore, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.

Answer:

Step-by-step explanation:

Liam saved $8 each week for 6 weeks.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's represent the amount of money Liam saves each week as x.

According to the problem, Liam saves an equal amount of money each week for 6 weeks, so the total amount he saves is 6x.

If we add this to the amount he started with, we get the total amount he has now: 6x + 62.

We also know that he now has $110, so we can set up an equation:

6x + 62 = 110

Subtracting 62 from both sides gives:

6x = 48

Dividing both sides by 6 gives:

x = 8

Therefore,

Liam saved $8 each week for 6 weeks.
