Answer:

104

Step-by-step explanation:

A rhombus diagonal bisect each other so that means half of the diagonal is equal to the other half.

Applying that, this means

Since they are equal we can divide AC by 2 to find AE and EC.

20/2=10

AE=10, EC=10

Same for DB

48/2=24

DE=24, EB=24

A rhombus diagonals are perpendicular to each other so each middle angle will measure 90 degree.

Looking closer, a rhombus has 4 right triangles. We only need to use one.

Look at triangle AEB. We know AE=10 and EB=24 and Angle E=90. We can apply pythagorean theorem to find side AB.

[tex] {ae}^{2} + {db}^{2} = {ab}^{2} [/tex]

[tex] {10}^{2} + {24}^{2} = {ab}^{2} [/tex]

[tex]100 + 576 = ab {}^{2} [/tex]

[tex]676 = {ab}^{2} [/tex]

[tex] \sqrt{676} = 26[/tex]

The perimeter of rhombus is equal to

4a, where a is the length of one side.

One side measures 26 so we can plug that in.

[tex]26 \times 4 = 104[/tex]

Answer: A

One a normal a curve the mean or average always occurs in the middle/ top of the curve.

Answer:

the answer is six and two

9514 1404 393

Explanation:

"Like" radicals can be added and subtracted in the same way any like terms can be combined. It can be helpful to simplify the radical as much as possible so that it can be seen whether the radicals are "like" or not.

Examples:

  √2 +√3 . . . . cannot be combined

  √2 +√8 = √2 +2√2 = 3√2 . . . . the simplified radicals can be combined

Answer:

The numerical value is 7.

Step-by-step explanation:

If 4 x is 3 y, then 8 x must be 3 x 2, which is obviously 6.

6y + y = 7y

--

7y/y

=7

[tex] \sf \red \: a = 6 \\ \sf \: b = 4[/tex]

Step-by-step explanation:

Answer:

the slope is 1 up and 7 left (mx part of the equation) and the 2 is where you start on the y axis. So you start at 2 on the vertical axis, and move up one and left 7, and put a point on where you land and continue.

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

Use the distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = \sqrt{(-7 - 5)^2 + (-7 - 9)^2}\\d = \sqrt{(-12)^2 + (-16)^2}\\d = \sqrt{144 + 256}\\d = \sqrt{400} = 20[/tex]

The distance between the points (5,9) and (-7,-7) will be 20 units.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D² = (x - p)² + (y - q)²  

The points are given below.

(5,9) and (-7,-7)

Then the distance between the points will be

D² = (5 + 7)² + (9 + 7)²  

D² = 12² + 16²  

D² = 144 + 256

D² = 400

D = 20 units

Answer:

40,000

Step-by-step explanation:

The computation of the amount spend by the customers is shown below:

For every 120 dollars will donate $3 dollars

Now for 1,000 it would spend

= 1000 × 120 ÷ 3

= 40,000

Answer:

Step-by-step explanation:

Look at the third line. The division would take place only if the 0 was ln(0). It isn't. It's just 0.

ln(x^2) = 2 * ln(x)

ln(3x) = ln3 + ln(x)

2 * ln(x) = ln(x) + ln(3)           Subtract ln(x) from both sides

ln(x) = ln(3)

Answer: the answer is x=4 so its option D

Step-by-step explanation:

i first set up a equation which looks like:

8x-12=20

then i have added 12 both sides so 20+12= 32 now im

left with: 8x=32

Now we divide so 32/8= 4

which why x=4

Answer:

47.74

Step-by-step explanation:

(tax is 8.5% of 100%, so you turn it into a fraction)

44 x .085 = 3.74

44 + 3.74 = 47.74

Answer:

v = -1 1/4

Step-by-step explanation:

1. -5 x -1 1/4 = 3 3/4

2. -5 x -2 = +10

3. 8 x 1 1/4 = 10

4. 5 x 1 1/4 = 6 1/4

5. 5 x 5 = 25

Now just substitute the values.

Hope that helps!

Step-by-step explanation:

Answer:

x = 3.6 in

Step-by-step explanation:

4/circumference = 1.1/6.28 radians in a full circle

circumference = 22.85 inches

22.85/3.14 = 7.28 inch diameter

7.28/2 = 3.6 radius

Answer:

y = -3x - 2

Step-by-step explanation:

Y = Mx + b

[slope = m, y-intercept = b]

plug in values:

y = -3x - 2

(P.S. - I saw your last question, sorry people aren't answering. I'll try my best to answer your questions if you have any others :) )

Without the y provided alongside the slope and y intercept, this problem can not be solved.
