Angle A and angle B are supplementary. The measure of angle A is 4 less than 7 times the measure of angle B. Find the measure of A and B.

Answers

A = 157, B = 23 The definition of supplementary angles is that they add up to 180 degrees. So A+B = 180. And A = 7B - 4. So write down the formula A + B = 180 Substitute the formula for A in terms of B 7B - 4 + B = 180 Combine terms 8B - 4 = 180 Add 4 to both sides 8B = 184 Divide both sides by 8 B = 23 Now calculate A in terms of B A = 7B - 4 A = 7 * 23 - 4 = 161 - 4 = 157 Verify that A and B add up to 180 157 + 23 = 180

The volume of a pyramid is 27 cubic centimeters and its height is 6 cm. Find the area and the base of the pyramid.

Answers

Final answer:

The area of the base of a pyramid with volume 27 cubic cm and height 6 cm is 13.5 square cm. If the base is a square, the length of each side of the base is approximately 3.67 cm.

Explanation:

The volume of a pyramid can be given by the formula V = (1/3) * Area of the base * Height. In your question, you have been provided that the volume V is 27 cubic cm and the height h is 6 cm. Then Area of the base would be (3 * V) / h = (3 * 27 cubic cm) / 6 cm = 13.5 square cm. Since the base of a pyramid can be of various shapes, we have only calculated the area here. Now I assume that the base is a square for simplicity. If the area A of a square is given by the formula A = side^2, we can find the side length of the base by taking the square root of the area = sqrt(A) = sqrt(13.5 square cm) = 3.67 cm approximately.

ABCD is a parallelogram. A is the point (2,5), B is the point (8,8) and the diagonals intersect at (3.5, 2.5). What are the coordinates of C and D? How do I work this out?

Answers

Midpoint of diagonals: [tex]\( (3.5, 2.5) \)[/tex]. Using midpoint formula, [tex]\( C(5, 0) \) and \( D(-1, -3) \)[/tex].

Since [tex]\(ABCD\)[/tex] is a parallelogram, its diagonals bisect each other. So, the midpoint of the diagonals gives the center of the parallelogram, which is the midpoint of [tex]\(AC\) and \(BD\)[/tex].

Given that the midpoint of the diagonals is [tex]\((3.5, 2.5)\)[/tex], we can find the midpoint of [tex]\(AC\) and \(BD\)[/tex].

The midpoint formula is given by [tex]\(\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)\).[/tex]

For the midpoint of [tex]\(AC\)[/tex]:

[tex]\[\left(\frac{2+x_C}{2}, \frac{5+y_C}{2}\right) = (3.5, 2.5)\][/tex]

From this, we get:

[tex]\[2+x_C = 7 \quad \text{and} \quad 5+y_C = 5\][/tex]

which gives [tex]\(x_C = 5\) and \(y_C = 0\)[/tex].

For the midpoint of \(BD\):

[tex]\[\left(\frac{8+x_D}{2}, \frac{8+y_D}{2}\right) = (3.5, 2.5)\][/tex]

This yields:

[tex]\[8+x_D = 7 \quad \text{and} \quad 8+y_D = 5\][/tex]

which results in [tex]\(x_D = -1\) and \(y_D = -3\)[/tex].

So, the coordinates of [tex]\(C\) are \((5, 0)\)[/tex] and the coordinates of [tex]\(D\) are \((-1, -3)\)[/tex].

17 − 2v = 41 solve v

Answers

Final answer:

To solve the equation 17 - 2v = 41, subtract 17 from both sides to get -2v = 24. Then divide both sides by -2 which gives v = -12.

Explanation:

To solve the equation 17 - 2v = 41 for v, first we need to isolate v on one side of the equation. We can start by subtracting 17 from both sides to rid the left side of numbers without the variable v. This gives us the equation:

-2v = 41 - 17

-2v = 24

Now, to solve for v, we divide both sides of the equation by -2:

v = 24 / (-2)

v = -12

Therefore, the solution to the equation is v = -12.

Integers = 6, 8, IO
Final answer:

The question is about finding three consecutive even integers whose sum is 24. The integers are determined to be 6, 8, and 10 by setting up and solving a simple algebraic equation.

Explanation:

To solve for the three consecutive even integers whose sum is 24, let's assume that the first even integer is x. Because we know that even integers occur 2 units apart, we can say that the next two consecutive even integers are x + 2 and x + 4 respectively.

Now, we know that the sum of these three integers is equal to 24. Therefore, we can set up an equation:

x + (x + 2) + (x + 4) = 24

By simplifying and solving the equation, we obtain x = 6. Therefore, the three consecutive even integers are 6, 8, and 10.

The value of expression 4m + 23 + np - 3 for m = 7, n = 2, and p = 8 is 64.

To solve the given expression, we substitute the given values of m, n, and p into the expression:

4m + 23 + np - 3

Given m = 7, n = 2, and p = 8, we substitute these values into the expression:

Answers

Answer: Second option.

Step-by-step explanation:

In order to find the degree of the power function represented in the given table, you must find the difference of the y-values (values of [tex]h(x)[/tex]) until they diferences are constant.

1) First differences:

[tex]-2-(-8)=6\\\\0-(-2)=2\\\\-2-0=-2\\\\-8-(-2)=-6[/tex]

2) Second differences:

You must find the differences between the First  differences. Then, you get:

[tex]2-6=-4\\\\-2-2=-4\\\\-6-(-2)=-4[/tex]

You can notice that the second differences are constant. This means that the degree of the power function  represented in the given table is:

[tex]Degree=2[/tex]

The degree of the power function represented in the table is [tex]\boxed2[/tex].Option (b) is correct.

Further explanation:

Given:

The options are as follows,

(a). 1

(b). 2

(c). 3

(d). 4

Explanation:

The highest power of the polynomial function is known as the degree.

The value of x is -2 and the value of the function is -8.

The value of x is -1 and the value of the function is -2.

The value of x is 0 and the value of the function is 0.

The value of x is 1 and the value of the function is -2.

The value of x is 2 and the value of the function is -8.

The function from the table can be expressed as follows,

[tex]f\left( x \right) = - 2{x^2}[/tex]

Substitute [tex]-2[/tex] for [tex]\text{x}[/tex] in equation [tex]f\left( x \right) = - 2{x^2}.[/tex]

[tex]\begin{aligned}h\left( { - 2}\right) &= - 2\times {\left( { - 2} \right)^2}\\&= - 2 \times 4\\&= - 8\\\end{aligned}[/tex]

The degree of the power function represented in the table is [tex]\boxed2.[/tex]Option (b) is correct.

Can someone answer questions 8-14 asap and show their work on a piece of paper thanks

Answers

8. So here, you know the angle of elevation and the adjacent, and you're looking for the opposite. So first, put the angle into a tan calculator, because tan is the opposite/adjacent.

What you get is 8.64 ish.

So now, since you know the adjacent, just multiply the two together. 

8.64 * 20 = 172.8, or about 173.

9. a.  You can use the pythagorean's theorem to find this, or a ^ 2 + b ^ 2 = c ^ 2.

Basically, as long as you know the two legs' lengths in a right triangle, or a and b, you can find the hypotenuse, or c.

The two legs' lengths are 35 and 58.

So 35 ^ 2 + 58 ^ 2 = c ^ 2

1225 + 3364 = c ^ 2

4589 = c ^ 2

Then, you can square root both sides

[tex] \sqrt{4589} [/tex] = c

About 68 = c

68 km

b. To do this, just divide the two together, to find the ratio of opposite / hypotenuse (sin), or 58 / 68, which equals about 0.85

Put that in the sin ^ -1 in a calculator to get about 58.211, or 58 degrees.

10. I'm sure there's a more efficient way to do this that I don't know about but I'm stupid. 

a. Whelp, me not knowing how to find the angle of indication/elevation leads to me just using tan because why not. 3.83 is about the answer, or 4.

b. Just multiply 15 by 15, to get 225 m.

11. umm, is there a b to this question?

a: sorry I don't know how to do this one :(

12. a. pythagorean's theorem, a ^ 2 + b ^ 2 = 5.6 ^ 2

Or a ^ 2 + b ^ 2 = 31.36

Since a = b,

a ^ 2 + a ^ 2 = 31.36

[tex]2a^{2} [/tex] = 31.36

/2                             /2

a ^ 2 = 15.68

a = [tex] \sqrt{15.68} [/tex]

about 3.96 = a

3.96 + 3.96 + 5.6 = 13.52

b. Use sin here. 28 degrees in one of those sin calculators is 0.47.

That means the opposite / hypotenuse = 0.47.

So just multiply 0.47 by the hypotenuse, or 10.7, to get about 5.

So the short side of the rectangle is 5.

So you can either do the same with cosine or use the pythagorean's theorem. Either way, you should get about 9.4.

So the perimeter is 5 + 5 + 9.4 + 9.4 = 28.8 (ish)

13. To find the outside length of one of the four triangles or the hypotenuse, since you know the opposite, use sine. Sine is opposite / hypotenuse. 50 degrees in a sin thing is about 0.77. So that means 1.4 / hypotenuse = 0.77, or 1.4 / 0.77, which equals about 1.82.

So the length of the hypotenuse is about 1.82. That times 4 is 7.28, or about 7.3.

14. I'm sorry I don't know how to do this one, I can try tho :(

inches per year - this could make sense as well because you could easily measure the number of inches a tree grew in a year. 

millimeters per week- I suppose this makes sense how fast the specific tree grew. So, if you are alllowed to pick two answers I think you could make a strong case to your teacher that this unit has the potential to be logical rate unit for tree growth. 

milliliters per minute - NO. I think that this would be an illogical rate unit to use for trees because their growth is so slow that it wouldn't change by a measurable amount in just a minuet.  

miles per hour - NO. Trees do not grow fast enough for this to be a logical unit rate to use.

Geometry proofs - paragraph proofs to formal proofs! Prove RS = TU

Answers

it is proven true using the definition of congruent segments :)
Final answer:

To prove RS = TU, we can use the congruence of corresponding parts of congruent triangles. By the side-angle-side (SAS) congruence postulate, if two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent. Therefore, RS = TU.

Explanation:

To prove that RS = TU, we need to show that the lengths of RS and TU are equal. In order to do this, we can use the congruence of corresponding parts of congruent triangles. Let's assume that triangles RST and TUV are congruent.

By the side-angle-side (SAS) congruence postulate, if two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

Since RST and TUV are congruent, we can conclude that RS and TU are congruent as well. Therefore, RS = TU.

The perimeter is minimum when the differentiation is equal to 0.2 - 84/x^2 = 02x^2 - 84 = 0x^2 = 42 x = 6.48
Thus, the minimum yards of string lights the manager need to enclose the area is  2(6.48) + 84 / 6.48^2 = 12.96 + 12.96 = 25.92 so it is approximately 26 yards

Alright, so we have 3.69/0.3. What I personally like to do is expand it so we have whole numbers, so we can multiply the equation by 100/100 to get 
369/30. 


and we know that 30 goes into 300 10 times due to that you simply add another 0. After that, we're left with 369-300=69. We know that 30*2=60, and 69-60=9. Therefore, we can add the 10 and the 2 up to get 12, and the remainder is therefore 9.

Now you have three answers add all together and here is your perimeter of a triangle.
Final answer:

The perimeter of a triangle with vertices at X(-2, -1), Y(2, 5) and Z(4, 3) is calculated using the distance formula to find the lengths of each edge. After calculating the lengths of the edges (XY, YZ and ZX), they are summed to produce the perimeter, which is 2√52 + √8.

Explanation:

To calculate the perimeter of a triangle with vertices at given coordinates, we must first compute the distances between each pair of points. Using the distance formula, d= √[(x₂-x₁)²+ (y₂-y₁)²], we find the distances between points X(-2,-1), Y(2,5) and Z(4,3).

Specifically, XY = √[(2 - -2)² + (5 - -1)²] = √[4² + 6²] = √52, YZ = √[(4 - 2)² + (3 - 5)²] = √[2² + -2²] = √8, and ZX = √[(4 - -2)² + (3 - -1)²] = √[6² + 4²] = √52.

Together, these line distances constitute the edges of the triangle. Adding these distances together (two √52 and √8), we find the perimeter of the triangle is 2√52 + √8.
