Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of packages of mix A nuts and let y represent the number of packages of mix B nuts

Since 8 ounces (oz.) of peanuts is used to produce a package of mix A and 6 ounces (oz.) of peanuts is used to produce a package of mix B. Also, No more than 120 oz. of peanuts can be used each day. This can be represented by the inequality:

8x + 6y ≤ 120             (1)

4 ounces (oz.) of cashew is used to produce a package of mix A and 6 ounces (oz.) of cashew is used to produce a package of mix B. Also, No more than 96 oz. of peanuts can be used each day. This can be represented by the inequality:

4x + 6y ≤ 96            (2)

The inequality from equation 1 and equation 2 is graphed using geogebra online graphing.

If x, y ≥ 0, the solution to the problem is:

(0, 0), (0, 16), (15,0), (6, 12)

Answer:

It should be that they both have the same area.

Step-by-step explanation:

since it's HALF the paper, the area should be the same. If you said the width of the paper was 8 inches and the length was 10, then the area would be 80 inches squared. Cut it in half for Calvin's paper and the area would be 40 inches squared, the same with Matthew's.

I hope that makes sense :)

Answer:

x = 8.6 cm

Step-by-step explanation:

Reference angle = 35°

Opposite side length = x

Hypotenuse = 15 cm

Apply trigonometric ratio to find x

Thus:

[tex] sin(35) = \frac{x}{15} [/tex]

Multiply both sides by 15

[tex] sin(35)*15 = x [/tex]

8.60364654 = x

x = 8.6 cm (nearest tenth)

Answer:

Fractions equivalent to 1/4 are 2/8, 3/12, 4/16, 5/20 so any of other fractions are not equivalent

Answer:

$38.48

Step-by-step explanation:

To find the sales tax you add 4% to 100%, which is 104%

Then you turn that into a fraction, which is 104/100

Then you multiply 104/100 by 37

You should get 38.48

Answer:

sin 4 x = 4 ( sin x − 2 sin 3 x ) √ 1 − sin 2 x

explanation: sin 4 x = 2 sin 2 x cos 2 x = 2 × 2 sin x cos x × ( 1 − 2 sin 2

= 4 sin x cos x − 8 sin 3 x cos x

Answer:

It would be 1/34 or 1/16.

Step-by-step explanation:

Add up how many kids there are in total and then see how many girls there are and write it like this: 18/34. Since it says a girl then you would do it as 1/34 or 1/16 it depends on how you look at it and or how you understand what the question is talking about.

Answer:

B. City P is above sea level and City R is below sea level

Step-by-step explanation:

A. City R is negative meaning it is below sea level however City Q is 0 meaning it is at sea level, so this statement is false.

C. Once again, City P is positive meaning it is above sea level but City Q is 0 meaning it is at sea level, so this statement is false.

D. Like before, City P is above sea level and City Q is at sea level not below, so this is, once again, false.

Answer:

85 degrees

Step-by-step explanation:

To start we can call the angle x and make an equation.

The complement of the angle would be 90 degrees - x

The supplement of the angle would be 180 degrees - x

Therefore, the difference between the measures of its supplement and nine times its complement is

180 - x - 9(90 - x) = 50

Solving,

180 - x - 810 + 9x = 50

8x - 630 = 50

8x = 680

x = 85 degrees.

Answer:

After three years you have earned $3,755.60

Step-by-step explanation:

The first year you start with $15,500 on account and earn $1,162.50 as interest

At the end of the first year the bank account is $16,662.50

The second year you start with $16,662.50 and earn $1,249.69 as interest

So at the end of the second year you have a sum of $17,912.19

Then on the third year you start with $17,912.19 and earn an interest of $1,343.41

So at the end of the third year the total of the bank account is $19,255.60

Now, if you sum the three interests $1,162.50+$1,249.69+$1,343.41 the total is $3,755.60 and this is your answer.

Answer:

y = 5x -7

Step-by-step explanation:

first find the slope using the formula y2-y1/x2-x1

-12 -3    -15

--------- = ----   =  5

-1 -2       -3

slope: 5

Now to find the intercept plug in the slope and the numbers into the equation then solve

y-y1=m(x-x1)

y - 3 = 5 (x -2)

y -3 = 5x -10

 +3          +3

y = 5x -7

Answer:

A) 1790.85

Step-by-step explanation:

Hi there!

In order to solve this problem, you’ll need to use the compound interest formula [tex]x = p(1 + \frac{r}{n} )^n^t[/tex]

p will be your principle, or starting amount, which is 1,000.

r will be your percentage, which is 0.06.

n will be the amount of times interest is compounded, since this question says compounded anually, your compound will be 1.

t is the time in years it is compounded, which is 10.

When the numbers are plugged in, we get [tex]x = 1,000(1 + \frac{0.06}{1})^1^0[/tex]

When we solve for this, we get 1790.85.

Hope this helps! :)
