Answer:

d = 20

Step-by-step explanation:

2d + 10 = 50 ( subtract 10 from both sides )

2d = 40 ( divide both sides by 2 )

d = 20

Answer:d=20

Step-by-step explanation:

Step 1: Subtract 10 from both sides.

2d+10−10=50−10

2d=40

Step 2: Divide both sides by 2.

2/d=40/2

d=20

Answer:

A) -8/5

Step-by-step explanation:

First, convert -8/5 and -5/8 to decimals

-8/5 = -1.6

-5/8 = -0.625

-0.5 is greater than -0.625 because it is closer to 0.

So, the only number less than -0.625 is -8/5, which is equivalent to -1.6

So, the correct answer is A) -8/5

Answer:

11.12 %

Step-by-step explanation:

Given that,

There are 90 early admission tickets.

There are 810 regular tickets.

We need to find the percentage of the tickets sold were early-admission tickets.

[tex]P=\dfrac{90}{810}\times 100\\\\=11.12\%[/tex]

So, the required percentage is 11.12 %.

Step-by-step explanation:

Answer:

10inches

Step-by-step explanation:

Let the length of one side of the square be  a

If the diagonal of a square is 10√2 inches

According to pythagoras theorem

a²+a² = (10√2)²

2a² = 100(2)

2a² = 200

a² = 200/2

a² = 100

a = √100

a = 10

Hence the length of one side of the square is 10inches

Answer:

13m

Step-by-step explanation:

[tex]d=50tan(15)=13m[/tex]

The required distance from the boat to the foot of the light house, which is at sea level is 13meter

Given that,

The top of a light house 50 meters high,

The angle of depression of a boat out at sea has a measure of 15°.

We have to determine,

To the nearest meter the distance from the boat to the foot of the light house, which is at sea level.

According to the question,

The angle of depression may be found by using this formula = opposite/adjacent.

The opposite side in this case is usually the height of the observer or height in terms of location.

Therefore, angle of depression = 15degree

Height of the light house = 50m

The distance from the boat of the light house is denoted by d.

Then the distance from the boat of the light house is given as.

[tex]tan15 = \frac{d}{50} \\\\d = 50 \times tan15\\\\d = 50\times0.26\\\\d = 13[/tex]

Hence, The required distance from the boat to the foot of the light house, which is at sea level is 13meter

Answer: 129°

m∠A  + m∠B =180°

51° + m∠B =180°

m∠B=129°

The angle measure of B in the parallelogram is 129°.

A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.

Given:

ABCD is a parallelogram.

And m∠A = 51°.

m∠A + m∠B = 180°

m∠B = 129°

Therefore, the angle measure of m∠B = 129°

Answer:

[tex]\displaystyle \frac{dS}{dt}=\frac{3}{50r}[/tex]

Step-by-step explanation:

Water is being pumped into an inflated rubber sphere at a constant rate of 0.03 cubic meters per second.

So, dV/dt = 0.03.

We want to show that dS/dt is directly proportional to 1/r.

In other words, we want to establish the relationship that dS/dt  = k(1/r), where k is some constant.

First, the volume of a sphere V is given by:

[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]

Therefore:

[tex]\displaystyle \frac{dV}{dt}=4\pi r^2\frac{dr}{dt}[/tex]

Next, the surface area of a sphere S is given by:

[tex]\displaystyle S=4\pi r^2[/tex]

Therefore:

[tex]\displaystyle \frac{dS}{dt}=8\pi r\frac{dr}{dt}[/tex]

We can divide both sides by 2:

[tex]\displaystyle \frac{1}{2}\frac{dS}{dt}=4\pi r\frac{dr}{dt}[/tex]

We can substitute this into dV/dt. Rewriting:

[tex]\displaystyle \frac{dV}{dt}=r\Big(4\pi r\frac{dr}{dt}\Big)[/tex]

So:

[tex]\displaystyle \frac{dV}{dt}=\frac{1}{2}r\frac{dS}{dt}[/tex]

Since dV/dt = 0.03 or 3/100:

[tex]\displaystyle \frac{3}{100}=\frac{1}{2}r\frac{dS}{dt}[/tex]

Therefore:

[tex]\displaystyle \frac{dS}{dt}=\frac{3}{50r}=\frac{3}{50}\Big(\frac{1}{r}\Big)[/tex]

Where k = 3/50.

And we have shown that dS/dt is directly proportional to 1/r.
