Step-by-step explanation:

Answer:

A   20°

Step-by-step explanation:

Explanation:-

Given graph

The corresponding angles are congruent (equal to each other)

(x+60)° = 4 x°

x + 60 = 4x

4x-x = 60

3x =60

x = 20°

The value of x=20°

Answer:

24 + c

Step-by-step explanation:

Answer:

134 degrees

Step-by-step explanation:

3x-6=180

3x=186

x=62

2x+10

=124+10

=134

Answer:

x-16+2x+10=180 x=62

Step-by-step explanation: 2(62)+10=134

Angle FDG=134

Answer:

h

Step-by-step explanation:

Answer: the volume would be 384 but if you want it separately it would 8*4= 32

8*12=96

4*12=48

but the total cost would be 176 after you add up the equations

and the surface area would be 352

hope this helped :D

Answer: It is 384 is for volume and  352 for surface area

Step-by-step explanation: 384 square inches for volume because you multiply all the numbers together.  V = LWH (volume=lengh+with+hight)

352 for surface area.

V = (8) x (4) x (12)

V = 384 inches squared

SA = 2(LH)+2(LW)+2(WH)

SA = 2(8x12) + 2(8x4) + 2(4x12)

SA = 192 + 64 + 96

SA = 348 inches squared

I hope this helps! =3

Answer:

a. S = {A,B,AB,O}

b. P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45

c. 0.45 = 45% probability that the person chosen at random has either type A or type AB blood

Step-by-step explanation:

a List the sample space for this experiment.

All possible blood types(A, B, AB or O). So

S = {A,B,AB,O}

b Make use of the information given above to assign probabilities to each of the simple events.

The proportions of blood phenotypes, A, B, AB, and O, in the population of all Caucasians in the United States are approximately .41, .10, .04, and .45, respectively.

So

P(A) = 0.41, P(B) = 0.1, P(AB) = 0.04, P(O) = 0.45

c What is the probability that the person chosen at random has either type A or type AB blood

P(A) + P(AB) = 0.41 + 0.04 = 0.45

0.45 = 45% probability that the person chosen at random has either type A or type AB blood

Answer:

Make sure you are using a perfect circle. This method won't work with ellipses, ovals or anything but a real circle. A circle is defined as all the points on a plane that are an equal distance from a single center point. The lids of jars are good household objects to use for this exercise.You should be able to calculate pi roughly because in order to get exact results of pi, you will need to ...

Measure the circumference of a circle as accurately as you can. The circumference is the length that goes around the entire edge of the circle. Since the circumference is round, it can be difficult to measure (that's why pi is so important). Lay a string over the circle as closely as you can. Mark the string off where it circles back around, and then measure the string length with a ruler.

Measure the diameter of the circle. The diameter runs from one side of the circle to the other through the circle's center point.

Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.[3] X Research source

Repeat this process with several different circles, and then average the results.

Step-by-step explanation:

Answer:

To find the area of a circle the equation is pir^2

To find the circumference of a circle it is 2pir

Step-by-step explanation:

Use formula

[tex] (\frac{b}{2} ) {}^{2} [/tex]

To add a third new term and factor to find the answer. Example

[tex]x {}^{2} + 6x = 18[/tex]

[tex]( \frac{6}{2} ) {}^{2} [/tex]

Which equal 9. so our equation look like

[tex] {x}^{2} + 6x + 9 = 18 + 9[/tex]

The only number that multiply to 9 and add up to 6 is 3. So we write our equation like this.

[tex](x + 3) {}^{2} = 27[/tex]

Take the sqr root of both sides

[tex]x + 3 = \sqrt{27} [/tex]

Subtract 3 from both sides

[tex]x = \sqrt{27} - 3[/tex]

Since a sqr root of a number can be positive or negative, the answer is

[tex] \sqrt{27} - 3[/tex]

or

[tex] - ( \sqrt{27} ) - 3[/tex]

Answer:

-1

Step-by-step explanation:

When solving a problem like this, you should do addition and subtraction from left to right. 2 +2 = 4, and 4-5=-1. Hope this helps!

Answer:

x = 2 and y = 2

Step-by-step explanation:

The given system of equations are :

12x+8y = 40 ...(1)

4x+5y = 18  ....(2)

Multiply equation (2) by 3.

12x+15y = 54 ...(3)

Subtract equation (1) by (3).

12x+15y-(12x+8y) = 54-40

12x+15y-12x-8y = 14

7y = 14

y = 2

Put the value of y in equation (2).

4x+5(2) = 18

4x+10 = 18

4x = 8

x = 2

The solutions of the given equations are x = 2 and y = 2

Answer:

3 skiers will be on the last chair

Step-by-step explanation:

Divide 609 skiers by 6 people per chair:

609 ÷ 6 = 101.5 (also can write as 101 and remainder of 3)

Multiply 101 • 6 = 606

609 - 606 = 3

Answer:

x= 16    y= -4

Step-by-step explanation:

So for the x intercept we get positive 16, or (16,0). And then for the y intercept we get negative 4, or (0,-4). Have a great day!! :)

12/5=2 1/6 lbs in each bag

Answer:

The relation (13,14), (13,5). (16,7). (18,13) is not considered a function

Step-by-step explanation:

Relations are only considered functions if each x value, which is the first number in each ordered pair or set of parentheses, has only one corresponding y-value, which is the second number in each ordered pair. The third option has two y-values, 14 and 5, for one x-value, 13. This means that it does not satisfy the requirements to be a function and therefore it is not a function.

The questions is basically saying make x isolated.

First add 3 to both sides.

y+3=2x-3+3

y+3=2x

Now divide both sides by 2

(y+3)/2=x

x=(y+3)/2

Done!

Answer:

Step-by-step explanation:

a) Volume of small cube box = 8 in³

      side³ = 8 = 2³

Side of small box = 2 in

b)  Side of larger box = 2 + 6 = 8 in

Volume of larger box = 8*8*8 = 512 in³

c) Number of balls to be shipped in the larger box = Volume of larger box ÷ Volume of smaller box

= 512 ÷ 8

= 64 golf balls
