Out of a total of 125 students surveyed, 48 said they did not like ice cream. Out of the total number of students surveyed, what percent said they did like ice cream?
Answer:
62% said they like ice cream
The percentage of students who liked the ice cream is given by the equation A = 61.6 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the percentage of students who liked ice cream be A
Now , the equation will be
The total number of students = 125 students
The number of students who didn't like ice cream = 48 students
The number of students who liked ice cream = 125 - 48
The number of students who liked ice cream = 77 students
So ,
The percentage of students who liked ice cream A = ( number of students who liked ice cream / total number of students ) x 100
Substituting the values in the equation , we get
The percentage of students who liked ice cream A = ( 77/125 ) x 100
On simplifying the equation , we get
The percentage of students who liked ice cream A = 0.616 x 100
The percentage of students who liked ice cream A = 61.6 %
Therefore , the value of A is 61.6 %
Hence , the percentage is A = 61.6 %

Angel uses 1/8 cup of sugar for 1/3 of a recipe. How much sugar is needed if Angel makes the entire recipe twice?
Answer:
3/4 cups of sugar
Step-by-step explanation:
So we know that 1/8 cup of sugar is for 1/3 OF a recipe.
So if we want the full recipe we jsut have to multiply 1/8 by 3 since its only worth 1/3 of the recipe.
You’ll get 3/8 cups of sugar for a whole recipe. The question asks for 2 full recipes and since we already know it takes 3/8 cups for one we can multiply that by 2 to find the amount of sugar needed for 2 full recipes.
You’d get 6/8 cups of sugar.

Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)
Answer:
Step-by-step explanation:
From points (-5,0),(1,0),(4,0) we know it has the form
y=(x+5)(x-1)(x-4)
y=(x^2+4x-5)(x-4)
y=x^3-4x^2+4x^2-16x-5x+20
y=x^3-21x+20
Then it must pass through the point (2,-2) so
-2=[2^3-21(2)+20]b
-2=[8-42+20]b
-2=[-14]b
b=1/7 so the equation is
y=(x^3-21x+20)/7

(This question is about trigonometric ratios)
9514 1404 393
Answer:
(b) 15.32
Step-by-step explanation:
You can use your triangle sense to answer this.
The side x will always be shorter than the hypotenuse, 20. This eliminates the last two choices.
If the angle is 45°, then the sides are equal at about 0.707 times the length of the hypotenuse. That would make them 0.707×20 = 14.14. Since the angle is greater than 45°, the opposite side will be greater than 14.14. Only one answer choice fits between 14 and 20: the second choice -- 15.32.
__
The mnemonic SOH CAH TOA reminds you of the relation ...
Sin = Opposite/Hypotenuse
sin(50°) = x/20
x = 20×sin(50°) . . . . multiply by 20 to find x
x ≈ 15.32 . . . . . . . . . use your calculator to evaluate

Answer: The answer is A
Step-by-step explanation:
Answer:
The answer is 34.6, or A.
Step-by-step explanation:
The formula for area is pi*r*r. This means that you will have to take the area, or A, and do this: [tex]\sqrt{\frac{a}{pi} }[/tex]. That would be that radius, so then multiply that by 2*pi, and that would give an answer of approximately 34.6.

You buy a new video game for $60.
The sales tax is 8%.
What is the total cost for the game including sales tax?
Answer:
$64.8
Step-by-step explanation:
To determine the tax, you want to make the percent into a decimal by moving the decimal point over two times the the left, which means 8% would be 0.08. Then, multiply the new decimal by the price. 60 times 0.08 is 4.8. Now, add the tax to the original price. 60+4.8=64.8, so therefore the total cost is $64.8

Find the mean absolute deviation for this data set.
2, 3, 1, 5, 4
The mean absolute deviation of the given data set is 1.2.
How to calculate the mean absolute deviation of a data set?Mean absolute deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. The formula for MAD is:
MAD =∑|x-m| / n
∑ is known as Sigma and means to sum up
| | are vertical bars that mean absolute value
x is each value
m is the mean
n is the total number of data points in your data set
Given: 2, 3, 1, 5, 4
n = 5
m = 2 + 3 + 1 + 5 + 4 = 15/5 = 3
∑|x-m| = |2-3| + |3-3| + |1-3| + |5-3| + |4-3| = 6
MAD =∑|x-m|/n = 6/5 = 1.2
Therefore, the mean absolute deviation of the set data is 1.2

Andres y Jorge fueron a una dulcería, Andrés compró 5 chocolates y 1 paleta por lo que pagó $26 y Jorge compró 2 chocolates y 1 paleta y pagó $14, ¿Cuál es el precio de cada chocolate y cada paleta?
Answer:
Precio del chocolate = x = $ 4
Precio de la paleta = y = $ 6
Step-by-step explanation:
Vamos a representar
Precio del chocolate = x
Precio de la paleta = y
Andrés y Jorge fueron a una tienda de dulces, Andrés compró 5 chocolates y 1 paleta por la que pagó $ 26
= 5x + y = 26 ...... Ecuación 1
Jorge compró 2 chocolates y 1 paleta y pagó $ 14.
2x + y = 14 ....... Ecuación 2
Combinando ambas ecuaciones juntos resolvemos usando el método de eliminación
Restamos la Ecuación 2 de la Ecuación 1
5x + y = 26 ...... Ecuación 1
2x + y = 14 ....... Ecuación 2
3 veces = 12
x = 12/3
x = $ 4
Resolver para y usando la Ecuación 1
5x + y = 26 ...... Ecuación 1
5 (4) + y = 26
20 + y = 26
y = 26 - 20
y = $ 6
Por lo tanto, el precio de cada chocolate y cada paleta:
Precio del chocolate = x = $ 4
Precio de la paleta = y = $ 6

Answer:
330
Step-by-step explanation:
Hello There!
The shown figure is a trapezoid with the following dimensions:
Height - 11m
Base 1 - 41m
Base 2 - 19m
Given this information we need to find the area
Remember the formula for the area of a trapezoid is
[tex]A=\frac{a+b}{2} h[/tex]
where a and b are bases and h is the height
Because we are given all of the information needed to calculate the area all we have to do is plug in the values into the formula
So...
[tex]A=\frac{19+41}{2} 11\\19+41=60\\\frac{60}{2} =30\\30*11=330\\A=330[/tex]
In conclusion the area of the figure is 330 square units
