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.

your answer in fully reduced form.
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.

A grocery store sells oranges by the crate. An empty crate weighs 1,000 grams. Each orange weighs at least 300
grams. Which inequality best describes the total weight in grams, w, of the crate of oranges in terms of, g, the
number of oranges in the crate?
A) w 300g + 1,000
B) w 2 300g - 1,000
C) w S 300g - 1,000
D) W S 300g + 1,000
Answer:
A.
[tex] w \ge 300g + 1000 [/tex]
Step-by-step explanation:
weight of empty crate = 1000 grams
weight of an orange = at least 300 grams
That means that the weight of an orange is equal to or greater than 300 grams.
Weight of g oranges = at least 300g
Total weight of crate and oranges = w
[tex] w \ge 300g + 1000 [/tex]

If LaTeX: P\left(6,-2\right),\:Q\left(-2,\:8\right),\:R\left(-4,\:3\right),\:P ( 6 , − 2 ) , Q ( − 2 , 8 ) , R ( − 4 , 3 ) ,and LaTeX: S\left(-9,\:y\right)\:S ( − 9 , y )find the value of LaTeX: yy so that LaTeX: PQ\bot RS.
Answer:
y = -1Step-by-step explanation:
First let us get the slope of the line PQ and RS
For PQ;
Given P(6, -2) and Q(-2,8)
slope m = 8-(-2)/-2-6
slope of pQ = 10/-8
slope of PQ = -5/4
For RS
R ( − 4 , 3 ) and S(-9, y)
slope of RS = y-3/-9+4
slope of RS = y-3/-5
For PQ to be perpendicular to RS, the product of their slope must be -1
Hence -5/4 (y-3/-5) = -1
y-3/4 = -1
cross multiply
y-3 = -4
y = -4+3
y = -1
Hence the value of y for PQ to be perpendicular to RS is -1

An art museum opens at 9 a.M. And closes at 5 p.M. The function V gives the number of visitors in a museum h hours after it opens. Explain what this statement tells us about the situation: V(1.25)=28
Answer:
What the equation is telling us is that after opening for 1 hour 15 minutes, there were 28 visitors
Step-by-step explanation:
The function we are given is ;
V(1.25) = 28
what this mean is that the number of visitors in the museum after 1.25 hours of opening is 28
1.25 hours is same as 1 hour (0.25 * 60) minutes
What is in the bracket is trying to convert the 0.25 hours to minutes
Since 1 hour is 60 minutes, 0.25 will be (0.25 * 70)
Which is 1 hour 15 minutes
So after opening for 1 hour 15 minutes, the museum had 28 visitors
A statement is convert into the equation by keeping the conditions equal in the form of expressions.
The given function tells that, in 1 hour, 15 minutes of the number of visitors, visit the museum is 28.
To identify the statement in the form of equation we need to know about the equation of statement.
How to make equation using statement?A statement is convert into the equation by keeping the conditions equal in the form of expressions.
Given information-
The art museum opens at 9 A.M.
The art museum closes at 5 P.M.
The function [tex]V[/tex] gives the number of visitors in a museum [tex]h[/tex] hours after it opens.
The statement in the form of equation given in the problem is,
[tex]V(1.25)=28[/tex]
As the above equation is the function of visitors visit the museum in to the number of hours.
Here bracket value (1.25) of function [tex]V[/tex] tells the number of hours in which 28 visitors visit the museum.
Convert 1.25 hours is the 1 hour and 0.25 hours.
AS one hour equal to 60 minutes thus, the number of minutes in 0.25 hours,
[tex]=0.25\times60\\=15[/tex]

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.
