Josh spent $30 at the movies. 1/5 was spent on a drink, 45% on a ticket and the rest on food. How much did he spend on food?
Answer:
$10.5
Step-by-step explanation:
Given data
Total amount=$30
Drink = 1/5*30= $6
Ticket= 45% of 30
=45/100*30
=0.45*30
=$13.5
The remainder is for food
=30-6-13.5
=$10.5

The number of trees are between 150 cm and 200 cm tall is 30 trees.
It is required to find the number of trees are between 150 cm and 200 cm tall.
What is histogram?A histogram is a graph that shows the frequency of numerical data using rectangles. It is used to summarize discrete or continuous data that are measured on an interval scale.
Given:
The histogram graph the number of trees are arranged in vertical direction or y -axis and height of trees are arranged in horizontal direction or x -axis.
According to given question we have,
The number of trees are between 150 cm and 200 cm tall
=30
Therefore, the number of trees are between 150 cm and 200 cm tall is 30 trees.

Step-by-step explanation:
Omar is driving to Denver. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Omar has 55 miles to his destination after 44 minutes of driving, and he has 41.5 miles to his destination after 62 minutes of driving. How many miles will he have to his destination after 74 minutes of driving?
Answer:
After 74 minutes of driving, he still has 32.5 miles to his destination.
Step-by-step explanation:
A linear relationship can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that a line passes through the points (x₁, y₁) and (x₂, y₂), then we can write the slope as:
a = (y₂ - y₁)/(x₂ - x₁)
Now let's go to the question.
We know that the distance to his destination is a linear function of his total driving time.
We know that he has 55 miles to his destination after 44 minutes of driving. We can write this as the point (44 min, 55mi)
We know that he has 41.5 miles to his destination after 62 minutes of driving, we can write this as (62 min, 41.5mi)
Then the slope of this equation will be:
a = (41.5mi - 55mi)/(62min - 44min) = -0.75 mi/min.
Then the linear equation is something like:
y = (-0.75 mi/min)*x + b
to find the value of b we can use the fact that this line passes through the point (44 min, 55mi)
This means that when x = 44 min, we must have y = 55mi
Then:
55mi = (-0.75 mi/min)*44min + b
55mi + (0.75 mi/min)*44min = b
88mi = b
Then the equation is:
y = (-0.75 mi/min)*x + 88mi
Now we want to know how many miles will he have to his destination after 74 minutes of driving, then we need to replace x by 74 min.
y = (-0.75 mi/min)*74min + 88mi
y = 32.5mi
After 74 minutes of driving, he still has 32.5 miles to his destination.

find the equation of the exponential function represented by the table below
x y
0 3
1 9
2 27
3 81
Answer:
y = 3^(1 + x)
Step-by-step explanation:
Notice that each time x increases by 1, y increases by a factor of 3.
Thus, the required equation has the form y = 3^x.
Check: If x = 0, do we get 3? No. Therefore we must modify the exponent:
y = 3^(1 + x)
Check: If x = 0, do we get 3? 3^(1 + 0) = 3 (correct)
If x = 2, do we get 27? 3(1 + 2) = 3^3 + 27 (correct)

Uma professora de artes pediu aos alunos para montarem mosaicos unindo peças. Nesse mosaico, essas peças deveriam ficar sempre ligadas pelos vértices, não poderiam se sobrepor e não deveria sobrar espaço entre elas. Além disso, para fazer esse mosaico, essa professora solicitou que todos os alunos utilizassem octógonos regulares, como o que está apresentado abaixo.
M100839H6_1
Para compor esse mosaico, junto com esses octógonos, os alunos tinham à sua disposição as peças do quadro abaixo.

Answer:
coloquei a letra d- II, III e IV
Step-by-step explanation:
Answer:
é a letra D (II, III e IV)
Step-by-step explanation:
se você reparar no ângulo interno da figura do octógono está mostrando 135º e a primeira figura que no caso não encaixa mostra 60º, fazendo essa soma daria um total de 195º, o que passa de 180º que é a metade de uma circunferência, então não daria certo, ficaria uma parte sobrando, não se encaixando no mosaico.

A box contains 4 pair of sunglasses. How many outcomes are in the sample space for pulling out a single pair, not returning it, then drawing out a second set of glasses.
a. 8
b. 12
c. 6
d. 9
Answer:
B.12
Step-by-step explanation:
For your first draw you have 4 possible options, then on your second draw you have 3 possible options since you took out a pair. So to figure out the number of possible outcomes you simply multiply the possibilities by each other to get the number of possible outcomes.
What is the intersection (x, y) of the two lines generated by the 2 equations:
y= x+3
y=-x +7
Answer:
x=2
y=5
Step-by-step explanation:
y= x+3...(1)
y= -x+7...(2)
(1) + (2):
y+y= (x+3) + (-x+7)
2y= (x-x) + (3+7)
2y= 10
y= 5
By substituting y=5 into (1),
we have
5= x+3
x+3=5
x= 5-3
x= 2

I don’t understand what I’m suppose to do. Can someone please help?
From the 64 values in the table on the left, count how many fall within the given ranges under the "classes" column in the table on the right. The "frequency" is the number of values in the data that belong to a given "class".
For example, "< -16.0" means "values below -16.0". Only one number satisfies this: -16.2 (first row, third column). So the frequency for this class is just 1.
Then for the range "-15.9 - 13.0", which probably means "numbers between 15.9 and -13.0, inclusive", the frequency is 0 because every number in the table is larger than the ones in this range.
And so on.

Determine whether the measures 2, √8, and √12 can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse,
or right. Justify your answer.
Answer:
C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = [tex]\sqrt{12}[/tex] and ([tex]\sqrt{12}[/tex] )² = 12
2² + ([tex]\sqrt{8}[/tex] )² = 4 + 8 = 12
Thus the triangle is right → C
Answer:
C.
Step-by-step explanation:
Squaring the numbers we get 2^2 = 4, 8 and 12.
Lets look at the relation between 4 8 and 12:-
12 = 4 + 8
- so it obeys the Pythagoras theorem.
It is a right triangle and the answer is C.

Henry painted a picture of his house on canvas. The actual width of
the driveway is 20 feet. If it is represented with a width of 4 inches on
the canvas, what was the scale factor used?
Answer:
The scale factor would be -5.
Step-by-step explanation:
If the driveway is 20 feet but 4 foot on the canvas. Then 20/4 is 5. But since the width is going from 20 to 4, the numbers are going down to it would be a negative scale factor. If it was going from 4 width to 20 width, the scale factor would be a positive 5.

Find the area of the figure
Answer:
16.28 m^2
Step-by-step explanation:
The bottom portion of this figure is a trapezoid with lengths 4 m and 6 m.
Thus, the average length of this trapezoid is 5 m, and the height is 2 m. This leads to (5 m)(2 m) = 10 m as the area.
The upper portion is a semicircle of radius 2 m. The area of this semicircle is
A = (pi)r^2 / 2, which here is A = (pi/2)(2 m)^2, or approximately 6.28 m^2.
Thus, the area of the entire purple figure is 16.28 m^2.

Chris tosses two number cubes labeled 1 to 6. What is the probability of rolling
double 4s?
Answer:
1/36
Step-by-step explananation:
The probability of rolling a 4 on one cube is 1/6. Any following throws are completely independent, so if we want the probability of rolling
double 4s, we multiply 1/6 by 1/6, obtaining 1/36.
The probability of rolling double 4s is 1/36.
