Answer:

44%

Step-by-step explanation:

The  percent increase would be calculated as the increase in insects caught divided by the original number of insects caught from the first week:

13-9 = 4 more insects caught.

4/9 = .44444

When doing percentages we multiply the decimal by 100, or move it over two places to the right, so it will be 44.4%

Numbers 4 and under round down.

Therefore,

44% is the increase

Answer:

slope = - [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, - 4) and (x₂, y₂ ) = (- 6, - 2)

m = [tex]\frac{-2+4}{-6+3}[/tex] = [tex]\frac{2}{-3}[/tex] = - [tex]\frac{2}{3}[/tex]

Answer:

slope= 2/-3

Step-by-step explanation:

Equation of the line: y=2/-3x-6

the slope being 2/-3

the y-intercept being -6

putting the slope as -0.66667 will still get you the same line going.

Answer:

-5

Step-by-step explanation:

f(x) = -x - 5

did before

f(-5)= 5-5

Answer - the answer should be:

-3x+4

down below is how i did it,

Step-by-step explanation:

use the formula mx+b=y

y is f(x)

m = -3

x = x

b = 4

so,

mx+b is -3x+4

Answer:

f(x)=-3x+4

Step-by-step explanation:

Slope= -3

(1-(-2))/(1-2)=3/-1= -3

Y-intercept= 4

Answer:

Answer:

B all square are regular polygons

Answer:

30, 85, 85

Step-by-step explanation:

(first, look at the photo)

3x - 5 = x + 55

3x - x = 55 + 5

2x = 60

x = 30

1) x = 30

2.angle = 3x-5

3.30 - 5 = 90 -5 = 85

3.angle= x + 55

30 + 55 = 85

hope this helps ^-^

Answer:

1/9x+1/9y-1/9z

Step-by-step explanation:

The given equation can be written as w = x/9 + y/9 + z/9.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given the linear equation,

w = 1/9 (x + y + z)

We have the distributive property which states that,

For any three numbers, p, q and r, p (q + r) = (p q) + (p r)

So applying distributive rule in the expression given, we get,

w = (1/9 x) + (1/9 y) + (1/9 z)

w = x/9 + y/9 + z/9

Hence the given linear equation w = 1/9 (x + y + z) can be written as w = x/9 + y/9 + z/9.

7.8=15/V

V=15/7.8

≈1.92 cm³

Answer: 8 percent

Step-by-step explanation:

120,000 - 110,400 = 9,600

9,600/120,000 = 0.08

0.08 * 100 = 8 percent

Answer:

D:8%

Step-by-step explanation:

If your starting value is $120,000 then it is marked down to $110,400 then the difference between the two is $9,600. Taking this value and dividing it by the starting value gives you the percentage. The number your calculator spits out is 0.08, so reading as a decimal, it is an 8% markdown.

A. 10 cm

Step-by-step explanation:

Answer: 14 oz

Step-by-step explanation:

CH/CR 3:2

3x/3=21/3

x=7

2*7=14 oz.

If you use 21 oz of chocolate, 14 oz cream cheese is needed.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

You can compare any two amounts that have the same units.

Given:

ratio of chocolate and cream cheese = 3:2

let the common ratio be x

Chocolate= 3x and Cream cheese = 2x

So,  21 oz of chocolate used

3x=21

x- 21/3

x=7

then, the cream cheese used

= 2 x 7

=14 oz.

Answer:

a. 3:4

b) 63 players

Step-by-step explanation:

From the question, we know that: Three out of seven soccer players wore headbands in a soccer league.

This means Number of soccer players who did not wear head bands = 7 - 3

= 4

a. Write the ratio of soccer players who wore headbands to soccer players who did not.

Soccer player who wore headbands : Soccer players who did not

= 3:4

b. If there were 36 players in the league who did not wear headbands, how many players were in the league?

Soccer player who wore headbands : Soccer players who did not

= 3:4

36 players in the league who did not wear headbands

Hence, number of players in the league who wore head bands is calculated as:

3/4 = x/36

Cross Multiply

4x = 3 × 36

x = 3 × 36/4

x = 27

The total number of players in the league

= 27 + 36

= 63 players

Answer:

B

Step-by-step explanation:

The average rate of change is synonymous with the slope.

So, essentially, we want to find the average slope of our function f(x) from x=0 to x=10.

So, we will use the two following points: (0,5) and (10, -20).

Recall the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, 5) be (x₁, y₁) and (10, -20) be (x₂, y₂). Substitute. This yields:

[tex]m=\frac{-20-5}{10-0}[/tex]

Subtract and reduce:

[tex]m=-25/10=-5/2[/tex]

So, the average slope of f(x) between x=0 and x=10 is -5/2.

Our answer is B.

And we're done!
