Answer:

Any angle that is on the inside of a shape is called an interior angle.

Step-by-step explanation:

Any angle that is on the outside of a shape is called an exterior angle. An exterior angle is made by extending one of the lines of the shape beyond the intersection point. ... Notice that the two angles make a straight line.

The correct choices are 29 feet = 348 inches, 352 yards = 0.2 miles, 372 feet = 124 yards, and 2 miles = 10560 feet.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have the ratio conversion table given.

mile: yard = 1: 1,760

yard: foot = 1 : 3

foot: inch = 1: 12

From the given conversion table:

29 feet = 29×12 inches

29 feet = 348 inches

Similarly,

352 yards = 0.2 miles   (1 yard = 1,760 miles)

372 feet = 124 yards

2 miles = 10560 feet  

Thus, the correct choices are 29 feet = 348 inches, 352 yards = 0.2 miles, 372 feet = 124 yards, and 2 miles = 10560 feet.

Answer:

First we divide 24 by 7.

24÷7=3.42

now we multiply 3.42 by 3 since that was the length of the mans shadow

3.42x3=10.26

The trees shadow is 10.26 feet long.

By the way, that is a very tall man

Step-by-step explanation:

7x - x

X by itself is the same thing as 1x.

So, if we rewrite the equation using 1x instead of just x:

7x - 1x

Now, we can subtract like we normally would.

7x - 1x = 6x

Step-by-step explanation:

The measure of each of the smaller angles is 60 degrees. The correct answer would be an option (A).

A polygon is a two-dimensional flat form with straight, completely closed sides. Straight, not curved, sides are required. Polygons, on the other hand, can have any number of sides.

Let's represent the measure of each of the four congruent interior angles of the pentagon "x". Then the fifth angle would have a measure of 5x.

The sum of the interior angles of a pentagon is equal to 180(n-2) degrees, where n is the number of sides of the polygon. In this case, n = 5, so the sum of the interior angles is equal to 180(5-2) = 540 degrees.

Therefore, the equation for the measures of the interior angles of the pentagon is:

x + x + x + x + 5x = 540

Simplifying the equation, we get:

9x = 540

Dividing both sides by 9, we find:

x = 60

So, each of the smaller angles has a measure of 60 degrees, and the larger angle has a measure of 5x = 5 × 60 = 300 degrees.

Step-by-step explanation:

100x8=800, 4*7=28, multiplied by 25 is 700, therefore making 800 greater than 700. Whenever comparing two multiplication problems, multiplying large numbers produces large results, so whichever starts larger will have an end result that is larger. 100 was large and it is smaller to its counter 25.

36 elevens really means 11x36, which is 396. 40 elevens really means 40x11, which is 440 minus 11x3 which is 407. 407 is greater than 396. The same logic applies here as the previous answer, the only difference is that the removal of three elevens is still larger than 36 elevens in this case.

12x24=288, 6x24=144, doubled makes it 288. In this case, the six is half of the twelve to begin with and then is made up for later by the fact that it is doubled.

When I solve math questions like these, I ignore the fact that it doesn't want a mathematical answer, do the math anyway and pull logic from it. (If your teacher checks, do it on a separate piece of paper, and then toss it.)

Answer:

6.25% of the day commuting

Step-by-step explanation:

45+45=1 hour 30 minutes

1.5/24

0.0625

6.25%

Answer:

6.25% of the day is spent commuting

Step-by-step explanation:

45+45=90 minutes

turn this into hour form because you want to make it easier to find out how much of a 24-hour day is spent commuting so 90 minutes = 1.5 hours

then you use 24 hours as the denominator since that is how many hours are in the day so 1.5/24=0.0625

to get this into a percentage, you multiply by 100 so 0.0625*100=6.25%

you can also solve this using solely minutes but converting to hours makes it easier in my opinion

Step-by-step explanation:

The solution of an equation is x= -1.11 and x = 2.11.

A polynomial equation of the second degree is quadratic, which means that at least one of its terms must be squared. Quadratic equations are another name for it. The quadratic equation generally looks like this:

ax² + bx + c = 0, where x is a numerical coefficient and a, b, and c are unknown variables.

Given equation -3x² + 2x + 4 = -x - 3

simplify the equation we get

3x² - 2x - 4 -x -3 = 0

3x² - 3x - 7 = 0

The equation is solved by the Quadratic formula

x =  (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex])/2a

a = 3, b = -3, c = -7

x = [-(-3) ± [tex]\sqrt{(-3)^{2} - 4(3)(-7)}[/tex]]/2(3)

x = (3 ± 9.643)/6

taking positive sign

x = 12.643/6 = 2.1072 = 2.11

taking negative sign

x = -6.643/6 = -1.1072 = -1.11

Hence the values of x are -1.11 and 2.11

The equation that describes the relationship is option A. y = 8 - 7x.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given are the values of x and y.

x : 0  1  2  3

y : 8  1  -6  -13

Equation of a line can be written as y = mx + d in slope intercept form.

m is the slope and d is the intercept along Y axis.

Slope of a line with two points (x, y) and (x', y') is,

Slope = (y' - y) / (x' - x)

Consider the points (0, 8) and (1, 1).

Slope, m = (1 - 8) / (1 - 0) = -7 / 1 = -7

Since we already have the point (0, 8), y intercept, d = 8.

Substituting these, we get the equation of line as,

y = -7x + 8 or

y = 8 - 7x

Hence the equation of the line is y = 8 - 7x.

The system of equations is represented by lines m and n are x - 3y = 6 and 5x − y = 10 option (B) is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

These tables of ordered pairs represent some points on the graphs of lines m and n.

Line m
