Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

[tex] \sin(45) = \frac{opposite}{hypotenuse} [/tex]

[tex] \sin(45) = \frac{3 \sqrt{2} }{x} [/tex]

[tex](x) \sin(45) = \frac{3 \sqrt{2} }{x} (x)[/tex]

[tex](x) \sin(45) = 3 \sqrt{2} [/tex]

[tex] \frac{(x) \sin(45) }{ \sin(45) } = \frac{3 \sqrt{2} }{ \sin(45) } [/tex]

[tex]x = \frac{3 \sqrt{2} }{ \sin(45) } [/tex]

[tex]x = 6[/tex]

Answer:

4 people

Step-by-step explanation:

plug 18+10.5x into your calculator, or just make a table labelling x and y.

note that x must not exceed $60 but can be equal to or less than $60. x=4 gives you the exact number of people, which is 4.

Answer:

(z - 2) (z^2 + 9)

Step-by-step explanation:

Factor the following:

z^3 - 2 z^2 + 9 z - 18

Hint: | Factor pairs of terms in z^3 - 2 z^2 + 9 z - 18 by grouping.

Factor terms by grouping. z^3 - 2 z^2 + 9 z - 18 = (z^3 - 2 z^2) + (9 z - 18) = z^2 (z - 2) + 9 (z - 2):

z^2 (z - 2) + 9 (z - 2)

Hint: | Factor common terms from z^2 (z - 2) + 9 (z - 2).

Factor z - 2 from z^2 (z - 2) + 9 (z - 2):

Answer: (z - 2) (z^2 + 9)

Answer:

The price of each big peach is: $0.45

Step-by-step explanation:

Given that

Total peaches = 270

The ratio of small to medium to big peaches

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

Now

[tex]Small\ peaches = \frac{2}{9} * 270 = 60\\Medium\ peaches = \frac{4}{9}*270 = 120\\Big\ peaches = \frac{3}{9} *270 = 90[/tex]

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

So,

Price of one small peach = $0.25

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

[tex]Price\ of\ all\ medium\ peaches = Total\ cost-(Cost\ of\ small\ peaches+ Cost\ of\ medium\ peaches)\\= 91.50 - (15+36) \\=91.50-51\\=40.5[/tex]

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches

So,

[tex]Cost\ of\ one\ peach = \frac{40.5}{90} = 0.45[/tex]

Hence,

The price of each big peach is: $0.45

0.45 cent

Given that

Total peaches = 270

The ratio of small to medium to big peaches.

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

So,

Price of one small peach = $0.25

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches.

So the price of each big peach is: $0.45

Answer:

C

Step-by-step explanation:

This is because 30d would be multiplying whatever the cost by 30, however with 0.3d you are taking 0.3 or 30% off of the whole number.

Jeremy factored the given expression and his steps are given.

To find:

The error in his solution.

Solution:

We have,

[tex]144x^2-100[/tex]

It can be written as

[tex]=12^2x^2-10^2[/tex]

[tex]=(12x)^2-10^2[/tex]

[tex]=(12x+10)(12x-10)[/tex]             [tex][\because a^2-b^2=(a+b)(a-b)][/tex]

Taking out common factors from each parenthesis.

[tex]=2(6x+5)2(6x-5)[/tex]

[tex]=4(6x+5)(6x-5)[/tex]

So, Jeremy was incorrect because the common factor is [tex]2\times 2=4[/tex] instead of 2.

Therefore, Jeremy made his mistake in his last step.

Answer:

3z < -4.8

* be sure to use the less than or equal to sign

Step-by-step explanation:

The inequality for the A number z times 3 is at most -4.8 is 3x < -4.8

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

A number z times 3 is at most -4.8

Now, the mathematical expression is

3z < -4.8

and, z< -1.6

Hence, the inequality is 3x < -4.8

Given:

The equation is

[tex]8x-1=-50[/tex]

To find:

The value of x by separating the variable.

Solution:

We have,

[tex]8x-1=-50[/tex]

Here, -1 is not next to the variable. So, move -1 to the other side of the equation by using the opposite operation. After moving -1 to the right side of the equation it will become +1.

[tex]8x=-50+1[/tex]

[tex]8x=-49[/tex]

Divide both sides by 8.

[tex]x=\dfrac{-49}{8}[/tex]

Therefore, the value of x is [tex]\dfrac{-49}{8}[/tex].

Answer:

1. 3 + 4 = 7 (they gave m already)

2. 9 - 4 = 5 (they gave both m and z)

3. 12 * 1/6 = 12/6 = 2 (they gave r)

4. 4(4) - 2 = 16 - 2 = 14 (they gave m)

5. 60 1/6 - 4 = 60/6 - 4 = 10 - 4 = 6

6. 3 1/6 * 1/6 = 3 * 1/12 = 3/12 = 1/4

All you have to do is substitute the variable with what they gave to u as a value
