Using percentages we know that 30% of students did not go on the field trip.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.So, the percentage of children that did not go to school:
The total number of students is 100.Students that went on the trip are 70.Students that did not go:
100 - 70 = 30 students30 students are % of 100:
30/100 × 100.30 × 10030%Therefore, using percentages we know that 30% of students did not go on the field trip.

Answer:
I believe drink A
Step-by-step explanation:
because it has more sugar in less ounces
Answer:
Drink A
Step-by-step explanation:
Ms. Raab and Ms. Levy both drink coffee in the
mornings.
Ms. Raab adds 1 more teaspoon to each cup of
coffee than Ms. Levy. Together, they both add 5
teaspoons of sugar to their coffees.
How many teaspoons of sugar does Ms. Raab add?
How many teaspoons does Ms. Levy add?
Set up an equation to show this, and then solve.
Answer:
Ms Levy = 2
Ms Rabb = 3
Step-by-step explanation:
Let :
Number of teaspoons taken by Ms Levy = x
Number of teaspoons taken by Ms Rabb = x + 1
Total number of teaspoons taken by both = 5
(Number of teaspoons taken by Ms Rabb + Number of teaspoons taken by Ms Levy) = total number of teaspoons taken
x + 1 + x = 5
2x + 1 = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2
Hence,
Number of teaspoons of sugar added by Ms Levy = x = 2
Number of teaspoons of sugar added by Ms Rabb = x + 1 = 2 + 1 = 3

A stereo speaker in the shape of a triangular pyramid has a height of 6 inches. The area of
the base of the speaker is 11 square inches.
What is the volume of the speaker in cubic inches?
Answer:
[tex]V=22\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
Height of a triangular pyramid = 6 inches
The area of the base of the speaker is 11 square inches
We need to find the volume of the speaker.
The formula for the volume of triangular pyramid is given by :
[tex]V=\dfrac{1}{3}Ah[/tex]
A is area of base and h is height
[tex]V=\dfrac{1}{3}\times 11\times 6\\\\=22\ \text{inches}^3[/tex]
So, the volume of the speaker is [tex]22\ \text{inches}^3[/tex].

The equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2
How to determine the function g(x)?The equation of the function f(x) is given as:
f(x) = x^3
The function g(x) is shifted down by 2 units and shifted left by 3 units, to get the function g(x)
This means that:
g(x) = f(x + 3) - 2
So, we have:
g(x) = f(x + 3) - 2
Hence, the equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2

The winning time for the men's 400-meter race in each of the Olympic Games from 1976 to 1996 can be modeled by the equation y = −0.054x + 44.54 , where x is the number of years after 1976 and y is the winning time in seconds. If the relationship continues, which equation could be used to predict the winning time in the year 2020?
Answer:
D. y = −0.054(44) 44.54
Step-by-step explanation:
The difference in years from 1976 to 1996 is 20 years
But from 1976 to 2020 the years would be 44
So here put the value of x as 44
Therefore the equation that could be used for predict the winning time for the year 2020 is y = −0.054(44) 44.54
Hence, the correct option is d.

Emily and Olivia are selling chocolate bars. Emily sold twice as many as Olivia. They sold a total of 48 bars. How many chocolate bars did they each sell?
Answer:
Olivia sold 16 chocolate bars and Emily sold 32.
Step-by-step explanation:
Let's set the amount of chocolate bars Olivia sold as x.
Since Emily sold twice as many, she would have sold 2x chocolate bars as a result.
Therefore, since the total is 48 bars, the equation would be [tex]x + 2x = 48[/tex].
[tex]x + 2x = 48[/tex]
[tex]3x = 48[/tex]
[tex]x = 16[/tex]
Hence, Olivia sold 16 chocolate bars.
Substituting the new value into the equation, we would find that Emily had sold 2x = 2(16) = 32 chocolate bars.
Checking the answer, we would find that (16 + 32) chocolate bars is indeed 48 chocolate bars, which fits the question.
Finally, we can arrive at the conclusion that Olivia sold 16 chocolate bars and Emily sold 32.

x+5y=5
-x+6y=-5
Please Help Me Thank you :)
Answer:
(5, 0)
Step-by-step explanation:
For the first line, we can isolate x by subtracting 5y on both sides.
x=5-5y.
Now we can use substitution on the second line!
-(5-5y)+6y=-5
= -5+5y+6y=-5
=-5+11y=-5
=11y=0
y=0
We subsitute y for the first line,
x+5(0)=5
x+0=5
x=5
We can check our work by plugging in x and y
5+5(0)=5 ✔
