First we need to find 60% of 20,000 sq ft.

so 20,000 x .60 = 12,000 sq ft.

since the parking space needs to be 12,000 sq ft, you'd have 8,000 sq ft. of the 20,000 left to construct the building.

Answer:

[tex]8,000ft^2[/tex]

Step-by-step explanation:

If 60% of the land area is destined to be a parking area, the other 40% of the total 100% remains for the construction.

So what we need is to find how much 40% of the  [tex]20,000ft^2[/tex]  is:

[tex]\frac{20,000}{100}*40=200*40=8,000[/tex]

or what is the same

[tex]20,000*0.4=8,000[/tex]

The space left to construct the building is [tex]8,000ft^2[/tex]

Answer:

y = (3 × 10^8 m/s)/x

Step-by-step explanation:

Speed of a wave is given by the product of wavelength and frequency.

Thus; speed = frequency × wavelength

If  x = wavelength and y = frequency then speed will be;

speed = yx

Thus to get wavelength, y;

y = speed/x , but speed is 3 × 10^8 m/s

Thus;

y = (3 × 10^8 m/s)/x

Answer:

The Answer is D y= x/3x10squareroot8 m/s

Semiannually means twice a year, so you multiple $67,000 by 2.

The annual salary is $134000

Semiannual is a term that describes something that is paid twice each year, typically once every six months.

Since semiannually salary is $67,000 so the annual salary will be

$67,000 x 2 = $134000

8.25 rounded off to the nearest whole number is 8, because the digit after the decimal point (2) is less than 5, which implies that we do not increase the whole number part.

To round off 8.25 to the nearest whole number, we look at the digit to the right of the decimal point, which is 2. Since this digit is less than 5, we keep the digit before the decimal point as it is. Therefore, 8.25 rounded off to the nearest whole number is 8.

When rounding numbers, such as rounding off 0.028675 to 0.0287 or 92.85 to 92.8, a key rule to remember is that if the dropped digit is greater than or equal to 5, you round up; if less, you round down. Applying this principle, we see that because 2 is less than 5, 8.25 rounds down, leaving us with 8 as the rounded result.

The equation is [tex]\[ 130x + 150y = 1920 \end{cases} \][/tex]

Let's represent the number of months Lance lived in Portugal as x and the number of months he lived in Brazil as y.

Since Lance lived in Portugal for x months and learned 130 words per month, the total number of words he learned in Portugal is 130x.

Similarly, since Lance lived in Brazil for y months and learned 150 words per month, the total number of words he learned in Brazil is 150y.

We're given that the total number of words Lance learned is 1920. So, the system of equations representing this situation is:

[tex]\[ \begin{cases} 130x + 150y = 1920 \\x + y = 14 \end{cases} \][/tex]

The first equation represents the total number of words Lance learned, and the second equation represents the total number of months he spent in both countries combined.

3x + 6y = 36

+ 3x - 6y =0

------------------------

6x = 36

x = 36/6

x = 6

3(6) - 6y = 0

18 - 6y = 0

-6y = -18

y = 3

Answer:

Solution (6 ,3).

Step-by-step explanation:

Given : 3x + 6y = 36 and 3x - 6y = 0

To find : use the elimination method to solve the system of equations.

Solution : We have given

3x + 6y = 36 ------(1)

3x - 6y = 0------(2)

_______________       (On adding both equations)

6x + 0 = 36 .

On dividng both sides by 6

x = 6.

On plug x = 6 in equation 1

3 ( 6) + 6y  = 36.

18 + 6y = 36 .

On subtracting both sides by 18

6y = 36 -  18.

6y = 18

On dividing both sides by 6

y = 3

Solution (6 ,3)

Therefore, Solution (6 ,3).

Answer:

1) [tex]b=12[/tex]

2) [tex]tan(22.6\°)=\frac{a}{12}[/tex] (Third option)

Step-by-step explanation:

Remember that:

[tex]cos\alpha=\frac{adjacent}{hypotenuse}\\\\tan\alpha=\frac{opposite}{adjacent}[/tex]

1) Given that:

[tex]cos(22.6\°)=\frac{b}{13}[/tex]

You know that b is the adjacent side of the right triangle.

To solve for b you must multiply both sides of the expression by 13. Then, the value of b is:

[tex]13*cos(22.6\°)=\frac{b}{13}*13\\13*cos(22.6\°)=b\\b=12[/tex]

2) Then, you have that the equation correctly uses the value of b  ( adjacent side) to solve for a (opposite side) is:

[tex]tan(22.6\°)=\frac{a}{12}[/tex]

The value for b is 12 and  [tex]tan(22.6 ^{\circ \:} )=\frac{a}{12}\\[/tex].

RIGHT TRIANGLE

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  

For solving this question, you need to apply trigonometric ratios for the right triangle.

This question informs [tex]cos (22.6)=\frac{b}{13}[/tex]. Here, you should remember that cos of an angle is calculated by the ratio between the adjacent side from the angle and the hypotenuse of the right triangle. Therefore, [tex]cos=\frac{adj}{hyp}[/tex].

From a calculator, you find cos(22.6°)=0.92321. Thus,

                                       [tex]cos (22.6)=\frac{b}{13}\\ \\ 0.92321=\frac{b}{13}\\ \\ b= 0.92321*13\\ \\ b=12.002\\ \\ b=12[/tex]

The second part of question asks how to find the tangent value. The tangent can be calculated by formula presented below:

                               [tex]tan(\alpha )=\frac{opposite \;side\;angle}{adjacent\;side\;angle}[/tex]

For the angle 22.6°, you have:

Therefore,  [tex]tan(22.6 ^{\circ \:} )=\frac{a}{12}\\[/tex]

Concept is trigonometry. The tangent of 30° is √3.

To find the tangent of 30°, we can use a special right triangle. One type of special right triangle is a 30-60-90 triangle. In this triangle, the ratio of the lengths of the sides opposite the angles are 1:√3:2.

Since we want to find the tangent of 30°, which is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle, we can set up the equation:

tan 30° = opposite/adjacent = (√3)/1 = √3

Answer: [tex]\dfrac{2}{13}[/tex]

Step-by-step explanation:

Given : A bag contains 6 red balls, 4 green balls, and 3 blue balls.

Total balls = 6+4+3=13

Probability of drawing first ball as green :

[tex]P(G)=\dfrac{\text{Number of green balls}}{\text{Total balls}}\\\\=\dfrac{4}{13}[/tex]

If the first ball will be green, then the total balls left in bag = 13-1=12 and number of red balls remains the same.

Now, The conditional probability of drawing a red ball given that first ball was green :-

[tex]P(R|G)=\dfrac{\text{Number of red balls}}{\text{Total balls left}}\\\\=\dfrac{6}{12}=\dfrac{1}{2}[/tex]

Now,  the probability that the first ball will be green and the second will be red will be :-

[tex]P(G\cap R)=P(G|R)\times P(G)\\\\=\dfrac{4}{13}\times\dfrac{1}{2}=\dfrac{2}{13}[/tex]

Hence, the required probability = [tex]\dfrac{2}{13}[/tex]

Answer:   32

Step-by-step explanation:

[tex]F(C)=\dfrac{9}{5}C+k\\\\-40=\dfrac{9}{5}(-40)+k\\\\-40=9(-8)+k\\\\-40=-72+k\\\\.\quad32=k[/tex]

Answer:

k = 32

Step-by-step explanation:

To get the value of k from expression:

[tex]F(C) = \frac{9}{5}C +k[/tex]

for F = -40 and C = -40, then:

[tex]-40 = \frac{9}{5}(-40)+k[/tex]

[tex]k =-40+\frac{9}{5}.40[/tex]

[tex]k = 72 - 40[/tex]

[tex]k = 32[/tex]

therefore, k should be 32 to get these answers.

The expression 7(3sqrt(2x)) - 3(3sqrt(16x)) - 3(3sqrt(8x)) simplifies to 3sqrt(2x) - 36sqrt(x) by first simplifying the square roots where possible, then distributing the coefficients, and finally combining like terms.

The expression given is 7(3sqrt(2x)) - 3(3sqrt(16x)) - 3(3sqrt(8x)). To simplify it, let's perform each operation step by step keeping in mind the properties of square roots and distributive property of multiplication.

Firstly, simplify inside the square roots where possible. sqrt(16x) = 4sqrt(x) and sqrt(8x) = 2sqrt(2)*sqrt(x) = 2*sqrt(2x). Now substitute these back into the equation:

7(3sqrt(2x)) - 3(3*4sqrt(x)) - 3(3*2sqrt(2x))

Now distribute the coefficients:

21sqrt(2x) - 36sqrt(x) - 18sqrt(2x)

Next, combine like terms.

21sqrt(2x) - 18sqrt(2x) - 36sqrt(x)

This results in:

3sqrt(2x) - 36sqrt(x)

Therefore, the simplified form of the expression is 3sqrt(2x) - 36sqrt(x).

Factoring is written as the product of simpler expressions/factors.

Step-by-step explanation:

Factoring (called "Factorising" in the UK) is the process of finding the factors.

Factoring is the method of finding what to multiply together to get an expression.

It is like "splitting" an expression into a multiplication of simpler expressions.

Example: factor [tex]2y+6[/tex]

Both [tex]2y[/tex] and 6 have a common factor of 2:

[tex]2y[/tex]  is 2 × y

6 is 2 × 3

So we can factor the whole expression into:

[tex]2y+6 = 2(y+3)[/tex]

So [tex]2y+6[/tex]  has been "factored into" 2 and y+3.

5.20 (8-pints) - 4.85 (gallon jug) = .35

The correct answer is (D).

Answer:

The correct answer option is 'then'.

Step-by-step explanation:

The "to prove" part of the information is the 'then' of the "if-then" statement.

For example, we have this problem:

[tex] y = 2 x - 1 [/tex]

If [tex] x = 3 [/tex], then find the value of y.

Here in this problem, we are asked that 'if' the value of x is true then prove it by substituting in the value.

Answer:

The answer is Then.

Step-by-step explanation:

The "to prove" part of the information is the THEN of the "if-then" statement.

If is the question like, it is not validated. You are asking something if it holds true.

For example: If it rains heavily, then water bodies fill up.

So, here you are proving that water bodies fill if rains are heavy.

Another example: If a = 3 and b = 6 then a+b = 9

We can see that 3+6=9

Then it is proved that a + b = 9

Answer:

A

Step-by-step explanation:

A is correct. Subtract 8 from both sides and then divide both sides by 3.

The inequality 3x + 8 ≥ 11 is represented by a line having a close circle at

x = 1 and going towards infinity.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, an inequality of line which is 3x + 8 ≥ 11.

3x ≥ 11 - 8.

3x ≥ 3.

x ≥ 3/3.

x ≥ 1.

This will be represented on a line with a close circle at x = 1 and the line will go towards infinity.
