hence, value of x = 8°

Answer: 100 weeks

Step-by-step explanation: I think this is like a trick question or what not. I’m going to give you my best answer. It takes 1 week to stack a block and he wants it to be 100 meter tall. 1 block is one meter tall and since it takes 1 week per stack you would do 100 x 1 equals to 100 weeks. I know it says the shortest time but thats my best guess

It will take 100 weeks to build the tower.

Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:

Therefore, it will take 100 weeks to build the tower.

Answer:

300x - y = -900

Step-by-step explanation:

The values of A, B, and C are 300, -1, and -900 respectively when the standard form of the equation is 300x - y = -900.

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The formula for a one-variable linear equation is written as Ax + BY = C, where a and b are constants and x is the variable.

Given equation is y = 900 + 300x, the standard form of the equation can be written as:-

Ax + Bx = C

y = 900 + 300x

Convert the above equation into standard form.

-300x + y = 900

Compare the equation to get A, B, and C.

A = -300

B = 1

C = 900

Therefore, the values of A, B, and C are 300, -1, and -900 respectively when the standard form of the equation is 300x - y = -900.

Kayla is wrong because the calculation will give different amounts since one gave $13.77 while the other one was $13.50.

Taking 10% off and then 15% off will give a price that will be calculated thus:

= $18 - (10% × $18)

= $18 - $1.80

= $16.20

Taking 15% off will then be:

= $16.20 - (15% × $16.20)

= $16.20 - $2.43

= $13.77

Now taking 25% off directly firm $18.00 will give:

= $18.00 - (25% × $18.00)

= $18.00 - $4.50

= $13.50

Therefore, Kayla is wrong.

Answer:

Perpendicular

slope Ab = undefined

slope Cd = 0

Step-by-step explanation:

slope AB = undefined, a vertical line has no slope

slope CD = 0 (a horizontal line has no slope)

Answer:

AB: Undefined

CD: 0

Perpendicular

Step-by-step explanation:

Slope is the change in y over the change in x

(sometimes called "rise over run")

Formula looks like this:

[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]

First let's find the slope of AB

[tex]\frac{7-3}{-5 --5 }[/tex]

[tex]\frac{7-3}{-5 +5 }[/tex]

[tex]\frac{4}{0}[/tex]

Undefined

Then the slope of CD:

[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]

[tex]\frac{9 -9}{-10 - 1 }[/tex]

[tex]\frac{0}{-11 }[/tex]

0

         If they are parallel they will have the same slope, perpendicular lines have negative reciprocals as the slope, and neither is neither

         Comparing the slope of our lines lead us to know that the two lines are perpendicular because AB is vertically up + down and CD is horizontally right + left

I hope this is correct and helps, have a nice day :D

Answer:

6/14

Step-by-step explanation:

divide the numerator and denominator by 3. 18 / 3 is 6 and 42 / 3 is 14. So your answer is 6/14.

Answer:

6/14

Step-by-step explanation:

Scaling the numerator and denominator means to multiply or divide both numbers by some number. "Scaling down" means to divide both the numerator and denominator by some value (in this case, 3). So you would have to divide the numerator by 3 and the denominator by 3.

18 / 3 = 6

42 / 3 = 14

So you would get the equivalent fraction 6/14 when you scale down the numerator and denominator by 3.

Answer: 5[tex]\sqrt{3\\}[/tex]

Step-by-step explanation:

This triangle is a 30-60-90 triangle. This means that: x = 2a where a is the shorter leg of the triangle and x is the hypotenuse, and b = a[tex]\sqrt{3\\}[/tex] where b is the longer leg of the triangle.

Hypotenuse = 2 * the length of the shorter leg

Longer leg = [tex]\sqrt{3\\}[/tex] * the length of the shorter leg.

Since just visually speaking, y is the longer leg and 5 is the shorter leg, let's substitute y and 5 into the equation solving for the length of the longer side:

y = [tex]\sqrt{3\\}[/tex] * 5

y = 5[tex]\sqrt{3\\}[/tex]

-3.5 / 7 = -.5

The value is -1/2.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

-3.5 ÷ 7

This can be written as a fraction.

= -3.5/7

Remove the decimal point.

= -35/70

Divide both the numerator and denominator with 7.

= -5/10

Divide both the numerator and denominator with 5.

= -1/2

Thus,

The value is -1/2.

Answer:

Step-by-step explanation:

It would be 120 because 4% of 125 is 5, so you subtract 5 from 125 to get 120. I am pretty sure that's how you do it.

5

Explanation:

We're multiplying each coordinate by 0.75, which is a value between 0 and 1. Whenever the scale factor is between 0 and 1, we always have a reduction. In this case, the linear dimensions are decreasing by 25% because 1-0.75 = 0.25 = 25%

So for instance, if the preimage had a side length of 12, then 0.75*12 = 9 is the corresponding image length. This is a reduction of 12-9 = 3. Then note how 3/12 = 0.25 = 25% is how much of a reduction we're dealing with.

The distance between 2 points is calculated with this formula:

[tex] \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} } [/tex]

• in the first exercise:

- the leftmost point has values (-5; 1), where -5 is the value of x1 and 1 is the value of y1

- the rightmost point has values (4; 0), where 4 is the value of x2 and 0 is the value of y2

then apply the formula:

[tex] \sqrt{(4 - ( - 5)) {}^{2} + (0 - 1) {}^{2} } [/tex]

[tex] \sqrt{(4 + 5) {}^{2} + (- 1) {}^{2} } [/tex]

• in the second exercise:

- the highest point has values (-4; 2), where -4 is the value of x1 and 2 is the value of y1

- the lower point has values (-4; -4), where -4 is the value of x2 and -4 is the value of y2
