I’m stuck on this question

Answer:

You will have to pay $22.05.

Step-by-step explanation:

We can solve this problem by making a proportion:

4.78 gallons/11 dollars = 9.58 gallons/x dollars

By cross-multiplying, we can solve for x:

4.78x = 105.38

x = 22.05

It is constant because otherwise it wouldn't be proportional

Given :

A building is of unknown height. At a distance of 400 feet away from the building .

An observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º .

To Find :

How far is the poster from the roof of the building .

Solution :

Height is given by :

[tex]h=d\times tan\theta[/tex]

( Here , [tex]\theta[/tex] is angle of elevation )

So , height of tower :

[tex]H=400\times tan 35^o\\\\H=280.08 \ feet[/tex]

For height of poster :

[tex]h=400\times tan 15^o\\\\h= 107.18\ feet[/tex]

Therefore , distance of poster from the roof of the building is :

[tex]( 280.08-107.18) = $$172.9\ feet[/tex]

Hence , this is the required solution .

Answer:

There's two ways to solve this.

Step-by-step explanation:

First way:

Let's divide the width and length by 2.3.

46÷2.3=20

69÷2.3=30

20×30

600 ft²

Second Way:

Let's find the area of the actual room.

46×69

3,174 ft²

Let's find the scale drawing squared.

2.3²=5.29

3,174÷5.29

600 ft²

Answer:

600

Selena is correct because she simplified correctly and then evaluated correctly after substituting the values for the variables.

Step-by-step explanation:

Answer:

Age of Cathy = 19

Step-by-step explanation:

Find:

Sum of their ages = 54

Assume;

Age of Andrea = x

Age of Beth = x + 1

Age of Cathy = x + 2

Sum of their ages = x + x + 1 + x + 2

54 = 3 x + 3

3 x = 51

x = 17

Age of Cathy = x + 2

Age of Cathy = 17 + 2

Age of Cathy = 19

Answer:

16x=1 x=1/16 or 0.0625

2/5x=1 x=5/2 or 2.5

Step-by-step explanation:

for 16x=1 divide both sides by 16, 1 divided by 16 is 1/16 or 0.0625

for 2/5x=1 multiply by the reciprocal of 2/5 which is 5/2. 5/2 times 1 is just 5/2 or 2.5.

Answer:

12

Step-by-step explanation:

the absolute value of any negative number is the number in positive form.

Answer:

Hello!

The value would 12 cause it is the absolute value

For example:

If the is negative 12 the absolute value would be the opposite, so it would be positive 12.

But if it was

|12| then it would stay the same

Answer:

B. p varies inversely as r

Step-by-step explanation:

Since, p varies directly as q

[tex] \therefore p\:\:\alpha \:\:q\\

\therefore p= kq.. (k = constant)... (1)\\

[/tex]

Since, q varies inversely as r

[tex] \therefore q\:\:\alpha \:\:\frac{1}{r} \\

\therefore q= \frac{k}{r} .. (k = constant)... (2)\\

[/tex]

From equations (1) & (2)

[tex] p = k\times \frac{k}{r}\\

p = \frac{k^2}{r}\\

p\:\:\alpha \:\: \frac{1}{r}\\

[/tex]

Hence, p varies inversely as r.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{1}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ \frac{1}{2} \times 2}[/tex]

Multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term.

[tex] \dashrightarrow{ \sf{ \frac{1 \times 2}{2 \times 1} }}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{2}{2} }}[/tex]

[tex] \dashrightarrow{ \sf{1}}[/tex]

Or, You can simply reduce the fraction with 2, which results to 1.

Hope I helped!

Step-by-step explanation:

The square root of -4 is the imaginary number: 2i The -6 stays the same. So add,, but don't combine real and imaginary numbers.

-6 + 2i

Answer:

30°

Step-by-step explanation:

[tex] \because \: \sin(90 \degree - \theta) = \cos \theta \\ \therefore \: \sin(90 \degree - 5 \theta) = \cos 5\theta....(1) \\ \\ \sin(90 \degree - 5 \theta) = \cos(180 \degree - \theta)...(2) \\ from \: (1) \: and \: (2) \\ \cos 5\theta = \cos(180 \degree - \theta) \\ 5 \theta = 180 \degree - \theta \\ 5 \theta + \theta= 180 \degree \\ 6\theta= 180 \degree \\ \theta = \frac{180 \degree}{6} \\ \\ \huge \red{ \boxed{\theta = 30 \degree}}[/tex]
