Answer:

Answers: 46, 23, and 111

Step-by-step explanation:

To answer, we need to know the angles. Therefore, give each angle a name. Angle 1 will be x, 2 will be y, 3 will be z. So, using this system of equations:

x=2y

z=y+88

x+y+z=180

Substituting, z = 1/2(x)+88, now plug z into the third equation:

x+1/2(x)+1/2(x)+88=180

this simplifies to 2x+88=180

subtracting 88 from both sides leaves 2x=92

x=46

plug this in to the first equation: 46 = 2y, so y = 23

plug this into the third one leaves z = 111

Hope this helps!

Final answer:

Using the sum of the interior angles formula for a polygon, S = (n - 2) x 180 degrees, and substituting the provided sum of 2280 degrees, it is calculated that the polygon has 14 sides.

Explanation:

To solve for the number of sides n in a polygon given the sum of the interior angles, we use the formula:

S = (n - 2) × 180°

where S is the sum of the interior angles in degrees. Given that the sum of the interior angles S is 2280 degrees, we can set up the equation:

2280 = (n - 2) × 180

Divide both sides of the equation by 180:

2280 ÷ 180 = n - 2

12 = n - 2

Now, add 2 to both sides of the equation to find n:

n = 12 + 2

n = 14

So, the polygon has 14 sides.

The percentage decrease(loss) of selling sweatshirts is 28%.

To find the percentage change of any value we need to divide by that change to the original value and then multiply by 100.

Percentage change = (change in value × 100)÷(riginal value).

Given that the selling cost of sweatshirts is $18.

The cost of the sweatshirt was $25.

Change of value

$25 - $18 = $7

By the formula

Percentage decrease = ($7)×100÷ ($25) %

Percentage decrease = 28% Hence,the percentage decreases is 28$.

Answer: [tex]x=2[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope of the line and "b" is the y-intercept.

We know that the slope of this line is:

[tex]m=-\frac{3}{2}[/tex]

And the y-intercept is:

[tex]b=3[/tex]

Since the line intersects the x-axis when [tex]y=0[/tex],  we can substitute values into  [tex]y=mx+b[/tex]:

 [tex]0=-\frac{3}{2}x+3[/tex]

The final step is to solve for "x", then:

[tex]-3=-\frac{3}{2}x\\\\(-3)(-2)=3x\\\\6=3x\\\\x=\frac{6}{3}\\\\x=2[/tex]

The x-intercept of the line is 2.

We must figure out the value of x when the y-coordinate is 0, in order to identify the x-intercept of a line.

We can express the equation of the line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept,

Given that the slope of the line is -3/2 and the y-intercept is 3.

Substituting the given values into the equation, we have y = (-3/2)x + 3.

To find the x-intercept, we set y = 0 and solve for x:

0 = (-3/2)x + 3

Subtracting 3 from both sides:

(-3/2)x = -3

To isolate x, we multiply both sides by -2/3:

x = (-3)(-2/3)

x = 2

Therefore, the x-intercept of the line is 2.

Answer:

The mass of each cereal box is 500 grams

Step-by-step explanation:

Remember that

1 K=1,000 g

we know that

The total mass of 8 cereal boxes is 4 kilograms

4 k=4*1,000=4,000 g

therefore

The total mass of 8 cereal boxes is 4,000 grams

To find the mass of each box, divide the total mass by eight

so

[tex]\frac{4,000}{8}=500\ g[/tex]

Answer:

f(x)  = ax + b;

f(0) = -5;

a·0 + b = -5;

b = -5;

f(1) = -3;

a·1 + (-5) = -3;

a - 5 = -3;

a = 5 - 3;

a = 2;

f(x) = 2x - 5;

Step-by-step explanation:

The linear function with the values f(0)=−5 and f(1)=−3 is f(x) = 2x - 5

The linear function can be represented as follows:

y = mx + b

where

m = slope

b = y-intercept

The y-intercept is the value of y when x = 0

Since,

f(0) = -5

Therefore,

b = -5

The equation will be as follows

f(x) = mx - 5

lets find the slope(m) using the f(1)=−3

-3 = m - 5

m = -3 + 5

m = 2

Therefore,

f(x) = 2x - 5

Step-by-step explanation:

70 combinations of four books can be made from eight different books.

Answer:

A. [tex]y = \frac{4}{3} x - \frac{3}{2}[/tex]

Step-by-step explanation:

First, we have to turn 4x - 3y = -12 into slope-intercept form (y = mx + b). To do this, we first have to isolate 3y.

4x - 3y = -12

    +3y    +12     Add 3y to both sides and add 12 to both sides

4x + 12 = 3y

3y = 4x + 12

Isolate y by dividing 3 from both sides.

y = [tex]\frac{4}{3}[/tex]x + 4

The graph that is parallel will have the same slope as this equation, which is [tex]\frac{4}{3}[/tex].

Therefore, A. [tex]y = \frac{4}{3} x - \frac{3}{2}[/tex] would be the correct answer.

Answer:

A

Step-by-step explanation:

Solve for y.

4x – 3y = -12

4x + 12 = 3y

y = 4/3 x + 4

Final answer:

The product rule for exponents allows you to add the exponents when multiplying two terms with the same base, simplifying the calculation. Examples include multiplying powers of the same number, or dealing with terms in scientific notation.

Explanation:

Understanding the Product Rule for Exponents

The product rule for exponents states that when you multiply two expressions with the same base, you can simply add the exponents. This rule simplifies the multiplication of exponentiated quantities.

Examples of Using the Product Rule

For instance, if you have 53 multiplied by 54, the product rule allows you to add the exponents: 53+4 = 57. Another example involves numbers in scientific notation. When you multiply 3.2 x 103 by 2 x 102, the result is 6.4 x 103+2 = 6.4 x 105.

If both terms have exponents, multiply the digit terms as usual and then add the exponents of the exponential terms. This concept also applies to logarithms, where the logarithm of a product of two numbers equals the sum of their individual logarithms.

Answer:

[tex](x-6)(x+1)[/tex]

Step-by-step explanation:

Factoring is usually just a bit of guess and check.  [tex]x^2-5x-6[/tex] is written in the form [tex]a^2+b+c[/tex], where [tex]a=1[/tex], [tex]b=-5[/tex], and [tex]c=-6[/tex].

Now, put them together in the form [tex](x-6)(x+1)[/tex].  We will now check this answer using the FOIL method.

First term in each parentheses: [tex]x * x = x^2[/tex]

Outside terms: [tex]x * 1 = x[/tex]

Inside terms: [tex]-6 * x = -6x[/tex]

Last term in each parentheses: [tex]-6 * 1 = -6[/tex]

Now, add these together: [tex]x^2 + x - 6x - 6 = x^2 - 5x - 6[/tex]

Step-by-step explanation:

1 bar of candy = $0.20

3 bars of candy = $0.50

To solve, multiply for both:

If you pay for each candy bar individually, they each cost $0.20. Multiply 9 with 0.20:

9 x 0.20 = $1.80

If you pay for the candy bars by 3's, they cost $0.50 each pack. Divide 9 with 3, then multiply by 0.50:

9/3 = 3

3 x 0.50 = $1.50

Answer:

The answer to this question is the first option:

Line segment TU is parallel to line segment RS because 32/36=40/45

Answer:

The correct option is 1.

Step-by-step explanation:

From the given figure it is clear that QT=32, TR=36, QU=40 and US=45.

The converse of side splitter theorem states that if a line divides two sides proportionally, then that line is parallel to the third side.

The ratio in which TU divides the two sides is

[tex]\frac{QT}{TR}=\frac{32}{36}=\frac{8}{9}[/tex]

[tex]\frac{QU}{US}=\frac{40}{45}=\frac{8}{9}[/tex]

[tex]\frac{QT}{TR}=\frac{QU}{US}=\frac{8}{9}[/tex]

It means the line TU divides two sides proportionally.

Using converse of side splitter theorem, Line segment TU is parallel to line segment RS because

[tex]\frac{32}{36}=\frac{40}{45}[/tex]

Therefore the correct option is 1.

Answer:

12 cm.

Step-by-step explanation:

The distance between the opposite sides is a perpendicular line so we can form a right angled triangle by drawing a perpendicular line from one corner of the parallelogram  to the opposite 24 cm side.

So  one angle of the parallelogram will have a sine of 8/16 = 1/2 so this angle =  30 degrees.

In a similar way to the above we form a right angled triangle  from the same corner by drawing a perpendicular line to the opposite 16 cm side.

This has an angle of 30 degrees (  opposite angles in a parallelogram are congruent).

So sine 30 = x / 24

1/2 = x /24

x = 12 feet.

Another way to do this is by noting that the 2 triangles are similar (because  2 corresponding angles are equal).

So  8/ 16 = x/24

16x = 192

x = 12 feet.

Final answer:

The distance between the 16 cm sides of the parallelogram is 12 cm, determined by calculating the area of the parallelogram and then using it to find the missing dimension.

Explanation:

The student in the question is dealing with a geometrical problem involving the calculation of the distance between sides of a parallelogram. To solve the problem, we must understand that the opposite sides of a parallelogram are equal in length, and the area can be calculated as the product of the base and the height (the distance between the parallel sides). The question is analogous to finding the height of a parallelogram when the area and the base are known and can be approached in a similar way to finding dimensions of scaled geometric figures.

Therefore, the distance between the 16 cm sides of the parallelogram is 12 cm.

Answer:

20°

Step-by-step explanation:

They are Vertically Opposite angles and hence are equal.

So, x + 40 = 3x.

Answer:

a. 20

Step-by-step explanation:

You are solving vertical angles. Put the measurements equal to each other:

x + 40 = 3x

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract x from both sides.

x (-x) + 40 = 3x (-x)

40 = 3x - x

40 = 2x

Isolate the variable x. Divide 2 from both sides:

(2x)/2 = (40)/2

x = 40/2

x = 20

a. 20 is your answer.
