Answer:

2.25 feet

Step-by-step explanation:

Alright so the scale is 1:3

(1 represents the diagram and 3 represents the actual doghouse)

In the diagram the length is 0.75ft

We can use this Information to set up this equation:

[tex]\frac{1}{3}=\frac{0.75}{x}[/tex]

Simplify: (cross multiply, if confused scroll down, I explained)

x=3(0.75)

x=2.25

Hope this helps

*************************

Cross multiplying:

It's simply this:

If   [tex]\frac{a}{b}=\frac{x}{y}\\[/tex]

Then we can say

a(y)=b(x)

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:

y=4x³ is not linear

Step-by-step explanation:

All of the equations produce lines, one of the characteristics of a linear function, except for y=4x³ where the graph is a curve. Refer to the graph attached to see this.

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:

22 km

Step-by-step explanation:

Well if sides of the triangle are 20 km and 21 km then it has to be 22 km

Respuesta:

Los 47.85m

Explicación paso a paso:

Altura máxima = u²sin²Ф / 2g

Dado

velocidad u = 40 m / s

Ф = 50 °

g = 9,81 m / s²

Sustituir'

H = 40²sin²50 / 2 (9,81)

H = 1600 (0,7660) ² / 19,62

H = 1600 (0,5868) /19,62

H = 938,8096 / 19,62

H = 47,85 m

Por lo tanto, la altura máxima es de 47,85 m.

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:

99 pages.

Step-by-step explanation:

First divide 165 by 5, to get 1/5th of the book. The answer is 33

Now, multiply 33 by 3 in order to get 3/5ths of the book.

You get 99 pages.

Answer:

22/17

Step-by-step explanation:

If a/b = 3/4, then a = 3 and b = 4.

6a + b/3a + 2b

Substitute the variables.

6(3) + 4/3(3) + 2(4)

Multiply 6 and 3, 3 and 3, and 2 and 4.

18 + 4/9 + 8

Add 18 and 4, 9 and 8.

22/17.

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

Hello I am an ace! answer: 8

Step-by-step explanation:

Volume for a cube is just length × width × height so you only need to know 1 for a cube because they will all be the same number so 8 is the answer because 8 × 8 × 8 = 512 Hope this helps!

Answer:

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).

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

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.
