Phillip writes the following equation to show how many hours h he needs to work to earn $108 at $12 per hour: h12=108. Is his equation correct? Explain.

Answer:

x = 11.31

y = 13.86

z = 19.60

Step-by-step explanation:

8/x = x/16

x^2 = 128

x = 11.31

x^2 + 8^2 = y^2

128 + 64 = y^2 = 192

y = 13.86

x^2 + 16^2 = z^2

128 + 256 = z^2

z^2 = 384

z = 19.60

Answer:

x = 6

Step-by-step explanation:

(8x - 4)° + (3x + 17)° = (17x - 23)° => exterior angle theorem

Solve for x

8x - 4 + 3x + 17 = 17x - 23

Add like terms

11x + 13 = 17x - 23

11x - 17x = -13 - 23

-6x = -36

Divide both sides by -6

x = 6

Answer:

(9×3÷4)+y

Step-by-step explanation:

(9×3÷4)+y = y+9 × 3/4

3/4 = 3:4

9× 3/4 = 9×3÷4

there is y+ (9× 3 ÷ 4)

yes I am pretty sure that's correct

Answer:

A. [tex]\frac{4}{10}[/tex]

B. [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Given - Box A contains 3 red and 2 blue marbles while Box B contains 2

            red and 8 blue marbles. A fair coin is tossed. If the coin turns up

            heads, a marble is chosen from Box A; if it turns up tails, a marble

            is chosen from Box B.

To find -  A. Find the probability that a red marble is chosen.

              B. Referring to above information, suppose that the person who

                  tosses the coin does not reveal whether it has turned up

                  heads or tails (so that the box from which a marble was

                  chosen is not revealed) but does reveal that a red marble was

                  chosen. What is the probability that Box A was chosen (i.e.,

                  the coin turned up heads)?

Proof -

As given ,

Box A : 3 red marbles and 2 blue marbles.

Box B : 2 red marbles and 8 blue marbles.

a.)

As we have to find the probability that a red marble is chosen.

A red marble is chosen in two different ways - either it can be from Box A or Box be .

If Box A is chosen , then Probability of red ball is [tex]\frac{3}{5}[/tex]

If Box B is chosen , Then Probability of Red ball is [tex]\frac{2}{10} = \frac{1}{5}[/tex]

Now,

Probability of Box A is Chosen = [tex]\frac{1}{2}[/tex]

Probability of Box B is chosen = [tex]\frac{1}{2}[/tex]

∴ we get

Probability that a Red marble is chosen =  [tex]\frac{1}{2}[/tex]×[tex]\frac{3}{5}[/tex] + [tex]\frac{1}{2}[/tex]×[tex]\frac{1}{5}[/tex] = [tex]\frac{3}{10} + \frac{1}{10} = \frac{4}{10}[/tex] = 0.4

b.)

Now,

Probability that Box A is chosen given that Red marble is chosen is

P(Box A | Red marble ) = [tex]\frac{(\frac{3}{5})(\frac{1}{2}) }{(\frac{3}{5})(\frac{1}{2}) + (\frac{1}{5})(\frac{1}{2})} = \frac{\frac{3}{10} }{\frac{3}{10} + \frac{1}{10} } = \frac{\frac{3}{10} }{\frac{4}{10}}[/tex] = [tex]\frac{3}{4}[/tex]

Answer:

Step-by-step explanation:

Add all the beads together to get your total amount of beads (This will be your denominator)

1+2+2+1=6 beads in total

You only want to focus on the amount of green beads. (Which is 2 and that will be you numerator)

[tex]\frac{Numerator}{Demonator}=\frac{green beads}{Total amount of beads}[/tex]

Answer:

B, 140

Step-by-step explanation:

Alright so if you know to do volume this should be a breeze!

First off what you want to do is find the volume of the outside prism.

V=whl=4·5·8=160

160

Then find the smaller prisms volume.

V=whl=1·5·4=20

20

Minus the smaller from the bigger

160-20=140

The answers B!

Answer: A. That order is taken into account​ (consider rearrangements of the same items to be different​ sequences).

Step-by-step explanation:

The combination is usually given by the formula below:

C n,x = n! / x! (n-x)!

We should note that the requirements for a combination rule include:

• That r of the n items are selected​ (without replacement).

• That there be n different items available.

• That order is not taken into account​ (consider rearrangements of the same items to be the​ same).

Therefore, the option that is not a requirement of the Combinations​ Rule, ​, for the items that are all​ different will then be option A"That order is taken into account​ (consider rearrangements of the same items to be different​ sequences).

Answer:

when x=1

3x+5.=3×1+5=8

when x=0

3x+5.=3×0+5=5

Step-by-step explanation:

when x=-1

3x+5.=3×-1+5=-3+5=2

Step-by-step explanation:

solution

here,

let the value of x be 1, then

3x+5

=3*1+5

=8

let the value of x be 2, then

3x+5

=3*2+5

=6+5

= 11

Step-by-step explanation:

This is the answer link: https://socratic.org/questions/how-do-you-divide-66-253-div-317  

The solution is, 600g of pasta cost £ 0.9.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

given that,

Pasta costs £1.50 per kg.

now we have to find,

How much does 600g of pasta cost

we know,

1 kg = 1000 grm.

so, we get,

1000 g Pasta costs £1.50

so, 1 g  Pasta costs £1.50/1000

so, 600 g  Pasta costs £1.50/1000 * 600

                                     = £ 0.9

Hence, The solution is, 600g of pasta cost £ 0.9.

Answer:

a = 6.65

Area = 15.84

Step-by-step explanation:

By cosine rule in the given triangle,

BC² = AC² + AB² - 2(AC)(AB)cos(C)

a² = 5² + 9²- 2(5)(7)cos(28°)

a² = 25 + 81 - 61.81

a = [tex]\sqrt{44.19}[/tex]

a = 6.65

Area of a triangle with given three sides = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Here, s = Average of lengths of all sides

a, b and c are the measures of the respective sides of the triangle.

s = [tex]\frac{6.65+7+5}{2}[/tex]

s = 9.325

a = 6.65, b = 5 and c = 7

Now substitute these values in the formula to get the area,

Area = [tex]\sqrt{9.325(9.325-6.65)(9.325-5)(9.325-7)}[/tex]

        = [tex]\sqrt{9.325\times 2.675\times 4.325\times 2.325}[/tex]

        = [tex]\sqrt{250.8313}[/tex]

        = 15.838

        = 15.84

Step-by-step explanation:

Answer:

y=-(x+11)(x-23)

Step-by-step explanation:

y=-(x+11)(x-23)

use the x intercepts they give you, and make it the opposite i.e. if it positive, then make it negative if it is negative make it positive

i.e. -11 equals 11

thus (x+11)

then, the graph is concave down, so it is negative at the front
