classify the triangle by its sides and by measuring of its angles

Step-by-step explanation:

Given that,

Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.

(a) Cost of c CDs = 12c

Cost of b books = 7b

Cost of p purse = 24p

Total amount = 12c+7b+24p

(b) Cost of 4 CDs = 12(4) = $48

Cost of 3 books = 7(3) = $21

Hence, this is the required solution.

Answer:

B

Step-by-step explanation:

Answer:

a. subtract 6 from both sides

Step-by-step explanation:

Given the algebraic expression;

-5c + 6 = 4

First of all, we would subtract 6 from both sides. This would eliminate the "6" on the left side.

-6 - 5c + 6 = 4 - 6

-5c = -2

5c = 2

Dividing both sides by 5, we have;

c = 2/5

Answer:

The least accurate statement regarding elements of a model for this setting is:

4 The unsatisfied demand in a year is max(Z – 45,000, 0).

Step-by-step explanation:

Expected annual demand for Prisdol = 50,000

Annual Plant Capacity = 45,000 units of drugs

Cost of building the plant = 45,000 * $16

Annual maintenance cost = 45,000 * $0.40

Production cost per unit = $0.20

Selling price per unit = $3.70

Sales revenue in a year = Z * $3.70,

where Z denotes the random demand in a year

b) Statements 1, 2, and 3 are accurate in this model setting.  However, statement 4 sets up a model that does not concur with the setting.  The unsatisfied demand in a year should be Z minus 45,000 if the plant produced full capacity.  Otherwise, it is Z minus annual production units.

Answer: (2,8)

Step-by-step explanation:

The origin is the point (0,0), so when you move two units right you land on the x-value of 2. From there you then add 8 units, putting you at the y-value of 8. Therefore, you end with the point (2,8) after this translation.

Answer:

x = 10

MB = 16

CM = 16

CB = 32

Step-by-step explanation:

Since it's the mispoint

2x - 4 = x + 6

Subtract x from both sides

x - 4 = 6

Add 4 to both sides

x = 10

MB = 2x - 4

MB = 20 - 4

MB = 16

CM = x + 6

CM = 16

CB = 16 + 16

CB = 32

Answer:

"0.0373" seems to be the appropriate solution.

Step-by-step explanation:

The given values are:

n₁ = 43

n₂ = 35

[tex]\bar{x_1}=217800[/tex]

[tex]\bar{x_2}=204700[/tex]

[tex]\sigma_1=30300[/tex]

[tex]\sigma_2=33800[/tex]

Now,

The test statistic will be:

⇒  [tex]Z=\frac{\bar{x_1}-\bar{x_2}}\sqrt{\frac{\sigma_1^2}{n_1} +\frac{\sigma_2^2}{n_2} }[/tex]

On substituting the given values in the above formula, we get

⇒      [tex]=\frac{217800-204400}{\sqrt{\frac{(30300)^2}{43} +\frac{(33800)^2}{35} } }[/tex]

⇒      [tex]=\frac{217800-204400}{\sqrt{\frac{918090000}{43} +\frac{1142440000}{35} } }[/tex]

⇒      [tex]=\frac{13400}{7347.93}[/tex]

⇒      [tex]=1.7828[/tex]

then,

P-value will be:

Step-by-step explanation:

The perimeter is determined by two times the length plus two times the width.

We will use the formula P = 2L+2W:

P = 2L+2W

P = 2(5x-y)+2(2x+3y)

P = (10x-2y)+(4x+6y)

P = 14x+4y

Given:

The slope of the line joining points (3,2) and (0,a) is -1.

To find:

The value of a.

Solution:

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], the slope of a line is:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The slope of the line joining points (3,2) and (0,a) is -1. So,

[tex]\dfrac{a-2}{0-3}=-1[/tex]

[tex]\dfrac{a-2}{-3}=-1[/tex]

Multiply both sides by -3.

[tex]a-2=-1(-3)[/tex]

[tex]a-2=3[/tex]

[tex]a=3+2[/tex]

[tex]a=5[/tex]

Therefore, the value of a is 5.

Answer:

Adult=58

Step-by-step explanation:

c=child, a=adult

6.4c+9.7a=1145 equation 1

c+a=149 equation 2

a=149-c modified equation 2 to isolate a

6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2

6.4c+1445.3-9.7c=1145

-3.3c=-300.3

c=91

solve for a

c+a=149

91+a=149

a=58

Check answer:

6.4c+9.7a=1145

6.4(91)+9.7(58)=1145

582.40+562.60=1145

1145=1145

Answer:

Step-by-step explanation:

Tan(theta) = Sin(theta) / cos(theta)

1/4 = sin(theta) / sqrt(1 - sin^2(theta) )    Cross multiply

sqrt(1 - sin^2(theta)) = 4*sin^2(theta)      Square both sides.

1 - sin^2(theta) = 16 * sin^4 (theta)         Transfer the left side to the right side.

0 = 16 sin^4(theta) + sin^2(theta) - 1

Use the quadratic formula to find a value for sin^2(theta)

a = 16

b = 1

c = - 1

I'll leave solving the quadratic to you.

There are two answers

sin^2(theta)= .22069

The other root is - 0.28 which you cannot use.

Sin(theta) = +/- 0.4698

Cos(theta) is < 0 in quads 2 and 3

So sin(theta) is positive in quad 2

and sin(theta) is minus in quad 3

Answer:

y-intercept: [tex](0,-\frac{5}{2} )[/tex]

x-intercept: [tex](-2,0)[/tex]

Step-by-step explanation:

Hi there!

Important things to note:

1) Find the y-intercept

[tex]-5x-4y=10[/tex]

Substitute x with 0

[tex]-5(0)-4y=10\\0-4y=10\\-4y=10[/tex]

Divide both sides by -4

[tex]\frac{-4y}{-4} =\frac{10}{-4} \\y=-\frac{5}{2}[/tex]

Therefore, the y-intercept is [tex]-\frac{5}{2}[/tex]. When written in (x,y) form, x will always be 0 while y is the y-intercept:

[tex](0,-\frac{5}{2} )[/tex]

2) Find the x-intercept

[tex]-5x-4y=10[/tex]

Substitute y with 0

[tex]-5x-4(0)=10\\-5x-0=10\\-5x=10[/tex]

Divide both sides by -5

[tex]-5x=10\\\frac{-5x}{-5}= \frac{10}{-5} \\x=-2[/tex]

Therefore, the x-intercept is -2. When written in (x,y) form, x will always be the x-intercept while y is always 0:

[tex](-2,0)[/tex]

I hope this helps!

Answer: 9000

Step-by-step explanation:

3500+5500=9000

5500=10years x 550/year

Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers. The balance that the account will have after 10 years is $9,000.

Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.

When Houa was born her parents started a college fund for her. They initially put $3500 in the account. They saved an additional $550 per year.

Therefore, the balance of the account after 10 years is,

Balance after 10 years = $3500 + $550(Number of years)

                                      = $3500 + $550(10)

                                      = $9,000

Hence, the balance that the account will have after 10 years is $9,000.

Answer:The zeros are 6, -5, 9

Step-by-step explanation:

The zeros of the polynomial function are x = 6, x = -5, and x = 9. The correct option is A.

In mathematics, a polynomial is an expression that solely uses the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables. It is made up of coefficients and indeterminates.

The zeros of the polynomial function are the values of x that make f(x) equal to zero.

The polynomial f(x) is written in factored form as:

f(x) = (x - 6)(x + 5)(x - 9)

The zeros of the polynomial are the values of x that make any of the factors equal to zero. Therefore, the zeros are:

x - 6 = 0, which gives x = 6

x + 5 = 0, which gives x = -5

x - 9 = 0, which gives x = 9

Thus, the zeros of the polynomial function are x = 6, x = -5, and x = 9.
