Eric spends 45 minutes getting to work and 45 minutes returning
home. What percent of the day does Eric spend commuting?
plz help and if you know the awnser pleasee tell me how to get thereee
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

At a zoo, 3 pandas eat a total of 181 1 2pounds of bamboo shoots each day. The male panda eats 3 times as much as the baby. The female eats twice as much as the baby. How many pounds of bamboo shoots does the female panda eat?
Answer:
6037.2 pounds of bamboo shoots does the female panda eat.
Step-by-step explanation:
Total pandas = 3
Total bamboo shoots eaten = 18112 pounds
Let baby panda eats bamboo = x
Male panda eats bamboo= 3x
Female panda eats bamboo = 2x
So, the equation will become
[tex]x+3x+2x=18112[/tex]
Now solving the equation to find value of x
[tex]x+3x+2x=18112\\6x=18112\\x=\frac{18112}{6}\\x=3018.6[/tex]
The value of x we get : x=3018.6
So, baby panda eats bamboo shoots = 3018.6 pounds
Male panda eats bamboo shoots = 3x = 3(3018.6) = 9055.8 pounds
Female panda eats bamboo shoots = 2x = 2(3018.6)= 6037.2 pounds
So, 6037.2 pounds of bamboo shoots does the female panda eat.
Use the table to answer the following question. What is an equation that describes this relationship?
The equation that describes the relationship is option A. y = 8 - 7x.
What is Slope?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.

What is a Quadratic equation?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

Compare the two expressions using <, >, or =. For each, explain how you can determine the answer without calculating.
1. 100 x 8 ____ 25 x (4 x 7)
2. 36 elevens ____ 40 elevens - 3 elevens
3. 12 x 24 ____ 6 twenty fours, doubled
Answer:
1. >
2. <
3. =
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.)

What is a polygon?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.
