Step-by-step explanation:

0+0+32

Answer:

The answer is 32

The number of 5-cent deposit containers the ecology club collected is 192.

a - b = 40 equation 1

0.05a + 0.1b = $24.80 equation 2

Where:

The first step is to multiply equation 1 by 0.1

0.1a - 0.1b = 4 equation 3

Add equation 3 and equation 1

$28.80 = 0.15a

a = $28.80 / 0.15

a = 192

Answer:

6b + 3a - 39n

Step-by-step explanation:

Expanding using the distributive property :

-3(-2b + 5a + 7n - 10a + 6n +4a)

Multiply all values in the bracket by - 3

6b -15a - 21n + 30a - 18n - 12a

Collect like terms

6b - 15a + 30a - 12a - 21n - 18n

6b + 3a - 39n

Step-by-step explanation:

domain is all real numbers

range is -2

Answer:

Domain: (-∞,∞)

Range: [-2,∞)

Step-by-step explanation:

The domain is (-∞,∞) because any real input for x works for any output of y.

The range is [-2,∞) because no y-value can be less than -2 for any real input x, but the range does include -2 (for example if x=3).

The number of data values between the lower quartile and the median is less than the number of data values between the upper quartile and the median.

Answer:

a₆ = 21875

Step-by-step explanation:

Using the recursive rule and a₁ = 7 , then

a₂ = 5a₁ = 5 × 7 = 35

a₃ - 5a₂ = 5 × 35 = 175

a₄ = 5a₃ = 5 × 175 = 875

a₅ = 5a₄ = 5 × 875 = 4375

a₆ = 5a₅ = 5 × 4375 = 21875

Answer:

Step-by-step explanation:

Here, we want to write as a single logarithm

Recall;

Log a + Log b = Log ab

Log a - Log b = Log (a/b)

so starting with the bracket, we have;

Log 2 + Log X - Log 3y

Furthermore, we have;

Log 2x - Log 3y

Finally, we have;

Log (2x/3y)

Answer:

5.8 feet

Step-by-step explanation:

this problem uses a 30-60-90° triangle

the ratio of sides in a 30-60-90° triangle, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2

let 'h' = height of ramp

we can use this proportion, then cross-multiply:

10/h = [tex]\sqrt{3}[/tex]/1

[tex]\sqrt{3}[/tex]h = 10

h = 10/[tex]\sqrt{3}[/tex]

after rationalizing the denominator we get:

(10[tex]\sqrt{3}[/tex] ) ÷ 3 which is approximately 5.8 feet

Using the trigonometric ratio, the height of the ramp is 5.77 feet.

Length of bicycle ramp = 10 feet

Angle with the ground = 30°

The tangent of an angle is the ratio of the opposite side to the adjacent of the triangle.

Suppose the height of the ramp is h.

So, [tex]tan30=\frac{h}{10}[/tex]

[tex]h=10tan30[/tex]

[tex]h=\frac{10}{\sqrt{3} }[/tex]

[tex]h=5.77[/tex] feet.

So,  the height of the ramp is 5.77 feet.

Hence, using the trigonometric ratio, the height of the ramp is 5.77 feet.

Answer: C. tan 307°<0

Step-by-step explanation: Quizzed

Given:

The functions are:

[tex]f(x)=|3x-5|+7x[/tex]

[tex]g(x)=-2x+9[/tex]

To find:

The function [tex](f+g)(x)[/tex].

Solution:

We have,

[tex]f(x)=|3x-5|+7x[/tex]

[tex]g(x)=-2x+9[/tex]

We know that,

[tex](f+g)(x)=f(x)+g(x)[/tex]

On substituting the values of given functions, we get

[tex](f+g)(x)=|3x-5|+7x+(-2x+9)[/tex]

[tex](f+g)(x)=|3x-5|+7x-2x+9[/tex]

[tex](f+g)(x)=|3x-5|+5x+9[/tex]

Therefore, the required function is [tex](f+g)(x)=|3x-5|+5x+9[/tex].

Answer:

36.87° and 53.13°

Step-by-step explanation:

the legs of the right triangle are 3 and 4 and the hypotenuse is 5

tan x = 3/4

x = arctan (3/4)

  = 36.87° =  measure on one acute angle

90 - 36.87 = 53.13° = measure of the other acute angle
