What does interior angle A of the polygon in the figure equal?

Answers

Answer 1

Answer: Based on the attached image, the interior angle A of the polygon in the figure equal 110 degrees. If you can see the image the angle A is equal to the angle on the other side. The angle A is an example of obtuse angle because has the size of more 90 degrees and less than 180 degrees. All the angles in the image are obtuse except the one angle in the top that measures 50 degrees.

Find the volume of an object with a mass of 63 grams and a density of 9 g/cm

Answers

you have to divide it 63 divide by 9 = 7

Final answer:

To find the volume of an object, divide its mass by its density.

Explanation:

The volume of an object can be found by dividing its mass by its density. In this case, the mass is given as 63 grams and the density is given as 9 g/cm. To find the volume, divide the mass by the density: Volume = Mass / Density.

Substituting the given values, we get Volume = 63 g / 9 g/cm. Simplifying the equation, we find that the volume of the object is 7 cm³.

Have vehicles gotten more fuel-efficient over the years? Between 1960 and 1999 the size and shape of automobiles in the United States has changed almost annually. The amount of fuel consumed by these vehicles has also changed. The following table describes the average fuel consumption per year per passenger car in gallons of gasoline.

Answers

This is correct. The changes in shapes imply changes in aerodynamics which means that the car takes less effort to move. This in turn means that it spends less gasoline. Also, the quality of the gasoline is higher due to increased number of octanes which also means that fuel is consumed less. Many other factors are included, but the final answer is: Yes, they have.

Devyn, Jessica, & Ashley earned a total of $228. Ashley earned $12 more than Jessica and Devyn earned $20 less than twice the amount Jessica earned. How much did each girl earn babysitting?

Answers

Answer:

Jesicaa=$59

Ashley=$71

Devyn=$98

Step-by-step explanation:

Let Jessica's earning be x:

$Jessica=x\n\nAshley=x+12\n\nDevyn=2x-20$

-Given that the total earnings for the three was$228. earnings per person is calculated as:

#Equate their earnings to the 228 to solve for x:

$x+(x+12)+(2x-20)=228\n\n4x-8=228\n\n4x=236\n\nx=59$

#Substitute for x in each earning equation to determine individual earnings:

$Jessica=x=59\n\nAshley=x+12=59+12=71\n\nDevyn=2x-20=59* 2-20=98$

Jaleel and Lisa are simplifying the expression 2(x - 2)^2. Jaleel’s method: 2(x - 2)^2 = 2x - 4 Lisa’s method: 2(x - 2)^2 = 2x. Whose method is correct and why? a) Lisa’s method is correct because 2(x - 2) equals 2x - 2. b) Lisa’s method is correct because 2(x - 2) equals 2x. c) Jaleel is correct because 2(x - 2) equals 2x - 2. d) Jaleel is correct because 2(x - 2) equals 2x - 4.

Answers

Answer:

The correct method is **c) Jaleel is correct because 2(x - 2) equals 2x - 2.**

Here's why:

Jaleel's method correctly expands the expression 2(x - 2)^2. When you square (x - 2), you get (x - 2)(x - 2), which simplifies to x^2 - 4x + 4. Then, multiplying this by 2 gives you 2(x^2 - 4x + 4), which simplifies further to 2x^2 - 8x + 8.

Lisa's method, on the other hand, incorrectly simplifies it as 2x. This is not the correct expansion of 2(x - 2)^2, as it neglects the square of (x - 2) and simplifies it incorrectly.

So, Jaleel's method is the correct one.
