A counter top is in the shape of a trapezoid. The lengths of the bases are 70 1/2 and 65 1/2 inches long. The area of the counter top is 1,244 square inches. Write and solve an equation to find the height

Answers

Answer:

height = (area x 2) / sum of bases

18.29 inches

Step-by-step explanation:

height = area x 2 / sum of bases

sum of lengths = 70 1/2 = 65 1/2 = 136

(1244 X 2) / 136 = 18.29

Triangle RST is made of points R(-10, 5.6), S(0, 7) and T(-6, -34).

If it is rotated 180° to form triangle R'S'T', enter the coordinates of T'.

?_? HELP

Answers

Answer:

Step-by-step explanation:

In the absence of additional information, will assume rotation is about the origin.

A 180° rotation about the origin has the equation

(x,y) => (-x,-y)

Therefore

R(-10, 5.6) => R'(10, -5.6)

S(0, 7) => S'(0, -7)

T(-6, -34) => T'(6, 34)

Answers

500 area

"Size" is ambiguous, so I'm giving you two answers.

When you hear that a TV is 40 inches, the length from one corner to the opposite corner diagonally is 40 inches. To solve, we use formula for hypotenuse, a^2 + b^2 = c^2.

20^2 + 25^2 = 32.02^2.

If that is what they mean by size, your answer is 32.02. However, size could refer to the area of the screen, which is calculated by length * width.

20 * 25 = 500

The answer in this case is 500.

Answer: Choice B

vertex = (3, -4)y intercept = (0, 5)x intercepts = (1, 0) and (5, 0)axis of symmetry:  x = 3

========================================================

Explanation:

The vertex is the lowest point for parabolas that open upward like this. The lowest point is (3, -4). If the parabola is flipped upside down, then the vertex would be the highest point.

--------

The y intercept is where the graph crosses the y axis. For any function, it will have at most one y intercept (some don't have any at all but the most you can have is 1 y intercept). The graph crosses the vertical y axis at (0,5). We can say in short "the y intercept is 5". The y intercept always occurs when x = 0.

--------

On the flip side, the x intercept always occurs when y = 0. This is where the graph crosses or touches the x axis. We have two such locations of (1,0) and (5,0). In short, we could say "the x intercepts are 1 and 5". The term "root" is another word we could use in place for "x intercept". Unlike the y intercept, we can have as many x intercepts as we want.

--------

The axis of symmetry is the vertical line through the parabola. It is the x coordinate of the vertex. So it's not a coincidence that the vertex is at (3,-4) and the axis of symmetry is x = 3, with those '3's repeated twice.

Fossil fuel resources are plentiful in areas that had certain types of ecosystems millions of years ago.

Step-by-step explanation:

Answer Choice 1. Incorrect. Minerals can be found all over the world in the crust of the earth, but generally in such small quantities that they are not worth extracting.

Answer Choice 2. Correct. Fossil fuels can be found more in areas that had a lot of plant growth because, after a long time, the heat and pressure changed the plants into fossil fuels.

Answer Choice 3. Incorrect. Minerals, fresh water, and biosphere resources are distributed unevenly around the planet as a result of past geologic processes.

Answer Choice 4. Incorrect. It depends more on the geological processes to produce large mineral deposits compared to the location of where they are.

Part 1: What percent of the eligible students voted for Carlos?

Part 2: How many votes did LaToya receive?

Part 3: How many votes did Stepanie recieve?

Part 4: Who won the election?

Answers

Answer:

Part 1) 30%

Part 2) 80 students

Part 3) 57 votes

Part 4) LaToya

Step-by-step explanation:

75 divided by 250 = 0.30 = 30%

32% = 0.32 and then 0.32 times 250 = 80 students

250 - 75 - 80 = 95 students that didn't vote for Carlos or LaToya. Then 0.60 times 95 = 57

LaToya had 80 votes, the most votes.

Harold found a job through a friend that works in HR for a large company. The job pays a yearly salary of $39K. What is the weekly salary based on this annual salary?

Answers

Answer:

Weekly salary of Harold = $750 (Approx.)

Step-by-step explanation:

Given:

Annual salary of Harold = $39K = $39,000

Find:

Weekly salary of Harold

Computation:

Number of weeks in a year = 365 / 7

Number of weeks in a year = 52.1425

Number of weeks in a year = 52 week (Approx.)

Weekly salary of Harold = Annual salary of Harold / Number of weeks in a year

Weekly salary of Harold = 39,000 / 52

Weekly salary of Harold = 750

Weekly salary of Harold = $750 (Approx.)

Answer:  y = 9sqrt(3)

"sqrt" is shorthand for "square root". If you need x as well, it is x = 18

=============================================================

Explanation:

This is a 30-60-90 triangle. The hypotenuse is twice that of the short leg, so the hypotenuse is x = 2*9 = 18 units.

The long leg is sqrt(3) times the short leg, so y = 9sqrt(3)

You could use the trig ratios (sine, cosine, tangent) to help find these values.

Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio, si avanza medio kilómetro en bus y lo demás a pie ¿Cuánto le falta caminar?

Answers

Answer:

Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.

Step-by-step explanation:

Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio. Dos tercios equivale a la fracción [tex]\frac{2}{3}[/tex] .

El estudiante avanza medio kilómetro en bus. Un medio equivale a la fracción [tex]\frac{1}{2}[/tex], por lo tanto un medio es la mitad de una cantidad.  Para calcular la distancia recorrida en bus se realiza la siguiente multiplicación:

[tex]\frac{1}{2} *\frac{2}{3}[/tex]

Resolviendo:

[tex]\frac{1}{2} *\frac{2}{3} =\frac{1*2}{2*3} =\frac{2}{6} =\frac{1}{3}[/tex]

Entonces, la distancia recorrida en bus es [tex]\frac{1}{3}[/tex] de kilómetro.

Para calcular la distancia recorrida a pie se calcula la diferencia entre la distancia total a recorrer por el estudiante y la distancia recorrida en bus. Esto es:

[tex]\frac{2}{3} - \frac{1}{3}[/tex]

Resolviendo:

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

Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.

Which of the following is the graph of:
(x-3)^2+(y+1)^2=9?​

Answers

Answer: Choice A

center = (3, -1)

radius = 3

==================================================

Explanation:

Rewrite the y+1 as y-(-1). Rewrite the 9 as 3^2

Then compare to the general form (x-h)^2+(y-k)^2 = r^2

You should find that h = 3, k = -1 and r = 3.

The center is (h, k) = (3,-1) and the radius is r = 3.

Choice A matches with that description.

Answer:

x = 16

Step-by-step explanation:

We know that the 2 given angles are same side interior angles, and therefore are supplementary (add up to 180°). The equation to solve for "x" would be written as:

(Angle 1) + (Angle 2) = 180°

(8x - 10) + (62) = 180°

8x + 52 = 180

8x = 180 - 52

8x = 128

x = 16

Therefore, x = 16
