A camel can drink 12L in 8 minutes.

Answer:

D

Step-by-step explanation:

an = 3/4 × an-1

let's see for n = 2

a2 = 3/4 × a1 = 3/4 × 4

n = 3

a3 = 3/4 × a2 = 3/4 × 3/4 × a1 = 3/4 × 3/4 × 4 = 9/16 × 4

so, we see, we multiply 3/4 one time less than n by itself and then by 4.

that makes D the correct answer.

the multiplication by (n - 1) in answer C would add 3/4 n-1 times instead of multiplying it n-1 times.

to apply n-1 multiplications we need to use n-1 as exponent.

Using proportions, it is found that the cat has to go 9/16 further to reach the gate.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

An entire distance is represented by the proportion of 1 = 100%. The cat has gone 7/16 of the distance, hence the fraction corresponding to the remaining distance that he has to go is given by:

1 - 7/16 = 16/16 - 7/16 = 9/16.

Hence the cat has to go 9/16 further to reach the gate.

The sum of the terms till infinity of the sequence 1, 1 / 4, 1 / 16, 1 / 64 will be 4 / 3.

We have the sequence:

1, 1 / 4, 1 / 16, 1 / 64. ​

Initial term = a

a = 1

Common ratio = d

d = 1 / 4

The formula for the sum of the terms to infinity is given by:

S_∞ = a / (1 – r)

S_∞ = ( 1 ) / (1 – 1 / 4)

S_∞ = 1 / ( 3 / 4 )

The average yearly salary of the final year is 67000 in dollars.

An average is a single number selected to stand in for a collection of numbers; it is frequently the product of the sum of the numbers divided by the total number of the collection. For example, the average of the integers 2, 3, 4, 7, and 9 is 5.

Let x = the average salary of an individual with the bachelor's degree, in dollars.

Then the average salary of an individual with master's degree is (2x - 35000)in dollars.

According to the sum of these salaries is 118000 dollars:

x + (2x-35000) = 118000

by solving we get

x = 153000/3

x = 51000

Hence, The average salary of an individual with the bachelor's degree is 51000 in dollars.  

the average salary of an individual with the master's degree (2*51000 - 35000) = 67000 in dollars.

Answer:

Step-by-step explanation:

The rate of change of the cost in dollars with respect to the number of t-shirts printed is $0.75 per shirt.

An equation is an expression that shows the relationship between two or more numbers and variables.

A linear function is in the form:

y = mx + b

Where m is the rate of  change and b is the initial value of y.

Given that the cost f(x) in dollars for printing x, t-shirts is given by:

f(x) = 100 + 0.75(x - 50)

f(x) = 0.75x + 62.5

Comparing with linear function, the rate of change is 0.75

The rate of change of the cost in dollars with respect to the number of t-shirts printed is $0.75 per shirt.

Let's consider an rational number for a moment. If I tell you that the fraction you used was 1/3 and gave you the first couple of numbers as in

1/3 = 0.33333.....

and asked you what the next number is, you should be able to tell me that the number to write down is 3.

Even something like 1/7 is well behaved.

1/7 = 0,142857142857142857 .... and tell you I want the next number, you should be able to see it as 1.

But an irrational number can't be handled that way. If I ask for the next digit after 5 when taking the square root of 2, you would have no idea what I was talking about without the help of a calculator.

Now if you multiply a rational by an irrational, you just get a bigger irrational, but it remains irrational.

The one time fee is -$17 and the one-time fee cannot not be applicable to this scenario because it is negative

The given parameters are

Hourly rate, r = 20.00

Number of hours, h = 5.5

Total amount = 93.00

The total amount is calculated as:

Total amount = One time fee + Hourly rate * Number of hours

So, we have

93.00 = One time fee + 20.00 * 5.5

Evaluate the product

So, we have

93.00 = One time fee + 110

Subtract 110 from both sides

So, we have

One time fee = 93.00 - 110

Evaluate the difference

So, we have

One time fee = -17

Hence, the one time fee is -$17

Amount cannot be negative.

Answer:

6.  ∠PVU = 58°

7.  y = 74°

Step-by-step explanation:

Angles on a straight line sum to 180°.

⇒ ∠USP + ∠PSV = 180°

⇒ 148° + ∠PSV = 180°

⇒ 148° + ∠PSV - 148° = 180° - 148°

⇒ ∠PSV = 32°

The interior angle of a rectangle at each vertex is 90°.

⇒ ∠VPS = 90°

Interior angles of a triangle sum to 180°.

⇒ ∠PVS + ∠PSV+ ∠VPS = 180°

⇒ ∠PVS + 32° + 90° = 180°

⇒ ∠PVS + 122° = 180°

⇒ ∠PVS + 122° - 122° = 180° - 122°

⇒ ∠PVS = 58°

From inspection of the given diagram:

⇒ ∠PVU = ∠PVS

⇒ ∠PVU = 58°

Opposites sides of a rectangle are parallel.

Therefore, GF is parallel to AB:

⇒ ∠CFG = ∠CBA = 32°

Interior angles of a triangle sum to 180°.

⇒ ∠FGC + ∠GCF + ∠CFG = 180°

⇒ y + 74° + 32° = 180°

⇒ y + 106° = 180°

⇒ y + 106° - 106° = 180° - 106°

⇒ y = 74°

After rounding, we can say that there are about 1,140 candles in the 22 packets.

First let's get the exact number, and then round it as we need to do.

We know that each packet contains 52 candles, and there are 22 packets, so the total number of candles is given by the product between these two values, which gives:

C = 52*22 = 1,144 candles.

Now we want to round it to the nearest ten, to do so, we need to look at the digit at the right of the tens unit (in this case the ones digit) and see, if it is 5 or more, we round up, if it is 4 or less, we round down.

We can see that it is a 4, so we round down here:

The scale from a playground to this drawing is 5 ft to 1 cm. The scale from the same playground to another drawing is 8 ft to 1 cm. What are the side lengths of the playground in the other scale drawing?

The side lengths of the playground in the other scale drawing is [tex]\frac{5a}{8}[/tex].

By using geometry we answer this question.

Geometry is nothing but  the branch of mathematics which deals with measurements of shapes.

Here, we take the scale from a playground to this drawing as "a" and The scale from the same playground to another drawing as "b".

First, we see the scale from a playground to this drawing.

[tex]\frac{a}{l}= \frac{1}{5}[/tex]

[tex]l=5a[/tex]

Now we see the scale from the same playground to another drawing.

[tex]\frac{b}{l} =\frac{1}{8}[/tex]

[tex]b=\frac{l}{8}\\[/tex]

Step-by-step explanation:

the slope is a line is always the factor of x.

and it is the ratio (y coordinate difference / x coordinate difference) when going from one point to another.

y = 2x + 4

has the slope 2. which is 2/1. so, for every increase of x by 1 unit, y increases by 2 units.

and this line has a y-intercept of 4 (the y-value when x = 0).

remember, the slope-intercept form of a line is

y = ax + b

a is the slope, b is the y-intercept.

a perpendicular slope (90°) turns that ratio upside down and flips the sign (because if the original line was going up, the perpendicular line is going down and vice versa).

so, the slope of the perpendicular line is -1/2.

the y-intercept was already given to us, so the desired line equation is

y = -1/2 x + 3

or

y = -x/2 + 3

Considering the definition of an equation and the way to solve it, the smallest four integers are 8, 10, 12, 14.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear.

The members of an equation are each of the expressions that appear on both sides of the equal sign.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being "x" n any integer, and knowing that:

So, the equation in this case is:

(2n + 2n +2 + 2n +4 + 2n + 6)÷ 4= 11

Solving:

(8n +12)÷ 4=11

8n +12= 11× 4

8n +12= 44

8n= 44 -12

8n= 32

n= 32 ÷ 8

n= 4

Then, the smallest four integers can be calculated as:

Finally, the smallest four integers are 8, 10, 12, 14.
