Find the value of xx, yy, and zz in the rhombus below.

Answer:

20

Step-by-step explanation

use the formula a²+b²=c²

since a=21 and c=29 you need to solve for b

Put 21 in for a and 29 in for c

21²+b²=29²

21²=441

29²=841

so then the equation would be 441+b²=841

subtract both sides by 441

then you have b²=400

now just find the square root of 400

√b²=√400

b=20

Answer:

Step-by-step explanation:

Area=bh/2=64, b=2h --->h2=64 --> h=8 (positive root) and b=16.

Answer:

250 watts

Step-by-step explanation:

If 16 floodlights together use 4000 watts of power, each floodlight uses 250 watts.

1. 16 floodlights use 4000 watts together

2. 4000÷16=250

3. 250 watts used by each floodlight

The answer might be incorrect, as power may not be straight forward to calculate with division, but hopefully the explanation helps!

Step-by-step explanation:

The  functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is  A = 500(1.1)^4

In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.

given:

P= $500

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 500.00[tex](1 + 0.1/1)(1)^4[/tex]

A = 500.00[tex](1.1)^4[/tex]

A = $732.05

Hence, the functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is  A = 500(1.1)^4

Answer:

Answer: D

Step-by-step explanation:

To compare the two lines, we want to a=make sure that they are in the same form.

3y-x=-7           [add both sides by x]

3y=x-7            [divide both sides by 3]

y=1/3x-7

Now that the equations are in the same form, we can compare them.

In order for the equations to have the same y-intercept, the "b" must be the same. The y-intercept for the first equation is -4, while the y-intercept for the second equation is -7. Therefore, A is not the answer.

If the lines are parallel, they must have the same slope. Parallel lines NEVER touch or cross, hence the slope has to be the same. The slope for the first equation is -13, while the slope for the second equation is 1/3. Therefore, B is not the answer.

We know that E is not the answer because the paragraph above proved that the slope are not equal.

We also know that the equations do not represent the same line. If they are the same line, the equations would be identical.

We know that D is the correct answer. A system of linear equaitons can only have ONE solution. We set the equations equal to each other to find the solution. The intersection point is the solution.

Therefore, we know that D is the right answer.

Answer:

y = 2/7x + 13/7 (slope intercept : y = mx + b)

Given two points (4, 3), and (-3, 1) You can start off with point slope because you are just given points.

Point slope: y - y1 = m(x - x1).

Point 1 : (4, 3) → (x1, y1). Point 2 : (-3, 1) → (x, y).

→ 1 - 3 = m(-3 - 4)

-2 = m ( -7 )

-2 = -7m

2/7 = m

m = 2/7.

Since you have the slope, all you need is one point.

y - 3 = 2/7 ( x - 4 )

y = 2/7 ( x - 4 ) + 3

y = 2/7x - 8/7 + 3

y = 2/7x - 8/7 + 21/7

y = 2/7x + 21/7 - 8/7

y = 2/7x + 13/7

*taydah*

______________

or if you don't like point slope, you can just find the slope between the two points, and then find the y intercept.

m = y2-y1/x2-x1

m = 3-1/4--3

m = 2/7

Then multiply the slope by the x of one of the coordinates, and subtract one of the y values from the coordinates from the slope multiplied by the x of the same coordinate.

let's use (-3, 1)

→ 1 - -3 ( 2/7 )

1 + 3 ( 2/7 )

1 + 6/7

13/7

*Here is the y intercept*.

Then just put this in the form y = mx + b and you are done!

y = mx + b → y = 2/7x + 13/7

Answer:

Step-by-step explanation:

Use the SOH-CAH-TOA method.

We are given an angle (37°).

We know a side that is opposite of the angle.And we are trying to find the hypotenuse.

So we use SOH

[tex] \sin(x) = \frac{o}{h} [/tex]

[tex] \sin(37) = \frac{0.6}{h} [/tex]

Isolate h

[tex]h = \frac{0.6}{ \sin(37) } [/tex]

Which gives us 1.

So the answer is 1.

The length of the rectangle is 18 cm, and the width is 24 cm as per the concept of perimeter.

Let the length of the rectangle be 3x and the width be 4x, where x is a common factor.

The perimeter of a rectangle is given by the formula:

Perimeter = 2 × (Length + Width)

Given that the perimeter is 84 cm, we can write the equation as:

84 = 2 × (3x + 4x)

Now, let's solve for x:

84 = 2 × 7x

42 = 7x

x = 42 / 7

x = 6

Now that we have the value of x, we can find the length and width of the rectangle:

Length = 3x = 3 × 6

           = 18 cm

Width = 4x = 4 × 6

          = 24 cm

Therefore, the length of the rectangle is 18 cm, and the width is 24 cm. The length and width are in the ratio 3:4, and the perimeter of the rectangle is indeed 84 cm.

Answer:

Step-by-step explanation:

The slope of the line passing through the given points is  [tex]\frac{2}{-9}[/tex]

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given are two points (2, 6) and (-7, 8) from which a line passes. We need to find the slope of the line.

We know that, the slope of a line passing through points (x₁, y₁) and (x₂, y₂) = (y₂-y₁) / (x₂-x₁)

In the given points, y₂ = 8, y₁ = 6, x₂ = -7 and x₁ = 2

Therefore, the slope of line = 8-6 / -7-2 = [tex]\frac{2}{-9}[/tex]

Hence, the slope of the line passing through the given points is  [tex]\frac{2}{-9}[/tex]
