Answer:

The last angle is 60 degrees

Step-by-step explanation:

All triangles add up to 180 degrees

Step 1:  Make an equation

What is the angle of a triangle if one angle is 68 and the other is 52.

68 + 52 + x = 180

Step 2:  Combine like terms

68 + 52 + x = 180

120 + x = 180

Step 3:  Subtract 120 from both sides

120 + x - 120 = 180 - 120

x = 60

Answer:  The last angle is 60 degrees

The sum of the angles in a triangle will be equal to 180°.

68 + 52 = 120°

180 - 120 = 60° (This is the 3rd angle)

Best of Luck!

The degree of the sum and difference of the polynomials.

3x⁵y - 2x³y⁴ - 7xy³ and -8x⁵y + 2x³y⁴ + xy³

The degree of sum = monomial with the highest power = 5 + 1 = 6

The degree of difference = monomial with the highest power = 3 + 4 = 7

Answer:

8 gallons of gasoline costs $30.63.

Step-by-step explanation:

Set up a proportion to solve for x, or the cost of 8 gallons of gasoline. The $47.86 goes on top of the first ratio, and 12.5 goes on top of the second. This is because the $47.86 is the cost of the 12.5 gallons of gasoline. Next, put x on the bottom of the first ratio and 8 on the bottom of the second ratio. This is because the amount of money you are trying to find, x, is the cost of the 8 gallons of gasoline. The proportion should look like this: [tex]\frac{47.86}{x} = \frac{12.5}{8}[/tex]

To solve the proportion, use cross multiplication. To do that, multiply 8 by 47.86 to get 382.88. Then, divide 382.88 by 12.5. The answer is 30.6304‬, so round to the nearest cent to get a total of $30.63.

Final answer:

The x-intercept of the line 5x - y = 10 is (2, 0), the y-intercept of the line 9x + 3y = -18 is (0, -6), and the equation 6x - 4y = -12 has an x-intercept at (-2, 0) and a y-intercept at (0, 3).

Explanation:

To find the x-intercept of a line, we set the value of y to zero and solve for x. For the equation 5x - y = 10, we set y to 0:

5x - (0) = 10

5x = 10

x = 2

The x-intercept is therefore the point (2, 0).

To find the y-intercept of a line, we set the value of x to zero and solve for y. For the equation 9x + 3y = -18, we set x to 0:

(0) + 3y = -18

3y = -18

y = -6

The y-intercept is therefore the point (0, -6).

For the equation 6x - 4y = -12, the x-intercept and y-intercept can be found similarly. Let's start with the x-intercept. Set y to 0:

6x - (0) = -12

6x = -12

x = -2

The x-intercept is the point (-2, 0). Now, for the y-intercept, we set x to 0:

(0) - 4y = -12

-4y = -12

y = 3

The y-intercept is the point (0, 3). Thus, for 6x - 4y = -12, the intercepts are x = -2 and y = 3.

Answer:

x=95

Step-by-step explanation:

320x+11400=440x

320*95+11400=440*95

30,400+11,400=41,800

41,800=41,800

The manufacturer needs to sell approximately 95 cell phones to cover its fixed costs of $11,400 per month. The profit per month depends on the number of units sold, with a contribution margin of $120 per unit after covering variable costs.

Answer:

100cm

Step-by-step explanation:

since the circumference is 20cm and formula for finding a circumference of a circle is c=2(pi)r, where r is radius and pi is constant value which is equivalent to 22/7. so the radius of 20cm circumference is 3.1847 by using this eqn c/2(pi)=r. now the calculated radius will b multiply by 5 to get 15.92cm which is put in cirumference formula i.e. c=2(pi)r we get 100cm circumference.

Answer:

In circle D, angle ADC measures (7x + 2)°. Arc AC measures (8x - 8)°.

Circle D is shown. Points A, B, and C are on the circle. Point C is on the opposite side of points A and C. LInes are drawn from point A to point B, from point B to point C, from point C to point D, and from point D to point A. Angle A D C measures (7 x + 2) degrees. Arc A C measures (8 x minus 8) degrees.

What is the measure of Angle A B C ?

36° *****

43°  

72°  

144°

Step-by-step explanation:

its 36°

Applying the central angle theorem, the measure of angle ABC is: a. 36°

Given:

m∠ADC = (7x + 2)° (central angle)

measure of intercepted arc AC = (8x - 8)°

Therefore:

(7x + 2)° = (8x - 8)°

7x + 2 = 8x - 8

8 + 2 = 8x - 7x

10 = x

x = 10

Thus:

m∠ABC is an inscribed angle = half of measure of intercepted arc AC

m∠ABC = 1/2(8x - 8)°

m∠ABC = 1/2[8(10) - 8]

m∠ABC = 36°

The answer is 9.1

To round to 2 significant figures, we have to find the first significant figure. We find the first sig fig by looking for the first nonzero digit in the number (it can be before or after the decimal point), which is "9"

The next digit is "0". This will also be a significant figure in our answer.

It may seem we are done now since we found the two significant figures. However, let's look at the digit after "0" to see if we need to round up or down.

The digit after "0" is "7". Since 7 is greater than 5, we round up the "0" to a "1" in our final answer, making the answer 9.1

Side note:

The definition and concept of significant figures can be very confusing overall, so please continue to ask questions if you are still struggling with them.

Step-by-step explanation:

We first need to find the slope of the graph of the lines passing through these points using:

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

The slope of the line that passes through (−12, 15) and (4, −5) is

[tex] m_{1} = \frac{ - 5 - 15}{4 - - 12} [/tex]

[tex]m_{1} = \frac{ - 20}{16} = - \frac{5}{4} [/tex]

The slope of the line going through (−8, −9) and (16, 21) is

[tex] m_{2} = \frac{21 - - 9}{16 - - 8} [/tex]

[tex] m_{2} = \frac{21 + 9}{16 + 8} [/tex]

[tex]m_{2} = \frac{30}{24} = \frac{5}{4} [/tex]

The product of the two slopes is

[tex]m_{1} \times m_{2} = - \frac{4}{5} \times \frac{5}{4} = - 1[/tex]

We can conclude -

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

y = mx also represents direct proportionality. We can write [m] as -

m = y/x

OR

y₁/x₁ = y₂/x₂

Given is a straight line.

The equation of a straight line is written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Now, from this we get -

m = -A/B     {Slope}

c = - C/A     {y - intercept}

So, the equation will be -

y = mx + c

We can also calculate slope by -

m = (y₂ - y₁)/(x₂ - x₁)

Therefore, we can write -

m = -A/B   → unit rate of change of [y] with respect to [x].

c = - C/A   → the point where the graph cuts the [y] axis.

Equation  → y = mx + c
