Answer:
Yes, the price the school pays each year in entrance fees is proportional to the number of students entering the zoo
Step-by-step explanation:
Relationships between two variables is proportional if their ratios are equivalent.
In 2010, the school paid $1,260 for 84 students to enter the zoo.
Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1260:84=15:1[/tex]
In 2011, the school paid $1,050 for 70 students to enter the zoo.
Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1050:70=15:1[/tex]
In 2012, the school paid $1,395 for 93 students to enter the zoo.
Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1,395:93=15:1[/tex]
As [tex]1260:84=1260:84=1,395:93=15:1[/tex],
the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.
Answer:
yes
Step-by-step explanation:
the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.
The perimeter of a rectangle is 54 feet. The width is 1 less
than the length. What are the dimensions of the rectangle?
Step-by-step explanation:
length=x
width=x-1
x + x + (x-1) + (x-1) = 54
4x - 2 = 54
4x = 56
x = 14 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
x = 14 ft
x - 1 = 14 - 1 = 13 ft
Perimeter= x + x + (x-1) + (x-1)
54 ft = 14 + 14 + (14 - 1) + (14 - 1)
54 ft = 28 + (13 +13)
54 ft = 54 ft
A bacteria colony starts with 5 bacteria at the beginning and triples every hour. How would
you write an explicit equation to model this situation?
A. f(x) = 3.5*
B. f(x) = 3x + 5
C. f(x) = 5x + 3
D. f(x) = 5.3%
Answer:
B. f(x) = 3x + 5
Step-by-step explanation:
Initial amount of bacteria N0 = 5 bacteria's
If the triple every hour,
The increase in bacteria in the colony after x hour will be 3*x =3x
x is the amount of hour.
Total amount of bacteria in the colony after x hour will be N0 + 3x
Let f(x) be the total amount of bacteria in the colony after x hour
f(x) = N0+3x
Since N0 = 5
f(x) = 5+3x
Re-arrange
f(x) = 3x + 5
Hence an explicit formula to model the equation is f(x) = 3x + 5

Find the x- and y-intercepts of the graph of the linear equation 3x+6y=24.
Answer:
y=0,4 and x=8,0
The x and y-intercept of the linear equation 3x + 6y = 24 will be (8,0) and (0,4) respectively.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given linear function,
3x+6y=24
At x-intercept, y = 0
3x = 24
x = 8 thus it will be (8,0).
At y-intercept , x = 0
6y = 24
y = 4 thus it will be (0,4)
Hence "The linear equation 3x + 6y = 24 will have x-intercepts of (8, 0) and (0, 4) correspondingly".

There are 4 pints of green paint in a gallon bucket. The paint is made from equal amounts of yellow paint and blue paint. To create a different shade of green, the mixture needs to be 80% yellow. How many pints of yellow paint need to be added to the bucket to make the mixture 80% yellow? Brandon says to get that shade of green, 6 pints of yellow paint need to be added to the bucket. Bianca says that won't work. In two or more complete sentences, explain who is correct and why. In your explanation, include the calculations to support the correct answer.
Answer:
Brandon is correct.
Step-by-step explanation:
Initially, there id 4 pints of green paint in the bucket.
As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket is 2 pint each.
Let x pints of yellow paint to be added to the bucket to make the desired shade.
Total amount of the paint in the bucket, after addition of [tex]x[/tex] pints of yellow color become [tex]4 + x[/tex] pint, in which the ampunt of yellow color is [tex]2+x[/tex] pints.
As, the ampunt of yellow color is 80% of the total amount of the mixture, so
[tex](4+x)\times 80\%=2+x[/tex]
[tex]\Rightarrow (4+x)\times \frac{80}{100}=2+x[/tex]
[tex]\Rightarrow 4(4+x)=5(2+x)[/tex]
[tex]\Rightarrow x=6[/tex]
So, 6 pints of yellow paint to be added to the bucket to make the desired shade.
Hence, Brandon is correct.
Answer:
Brandon is correct that the mixture needs 6 more pints of yellow paint.
50%(4 pints) + 100%(x pints) = 80%(4 + x pints)
2 + x = 3.2 + 0.8x
0.2x = 1.2
x = 6
Bianca is correct because adding the 6 pints won't fit in the gallon bucket. Adding 6 pints of yellow to the original 4 pints of green is 10 pints, which will not fit in the 1-gallon bucket. (1 gallon = 8 pints)

Given m angle7=38^ and m angle10=102^ find the measure of each missing angle
please show work to help me
[tex]\angle 1 = 78\\\angle 2 = 102\\\angle 3 = 78\\\angle 4 = 102\\\angle 5 = 38\\\angle 6 = 142\\\angle 7 = 38\\\angle 8 = 142\\\angle 9 = 78\\\angle 10 = 102\\\angle 11 = 78\\\angle 12 = 102\\\angle 13 = 38\\\angle 14 = 142\\\angle 15 = 38\\\angle 16 = 142[/tex]
The measure of the angles will be ∠1 = 78°, ∠2 = 102°, ∠3 = 78°, ∠4 = 102°, ∠5 = 38°, ∠6 = 142°, ∠7 = 38°, ∠8 = 142°, ∠9 = 78°, ∠10 = 102°, ∠11 = 78°, ∠12 = 102°, ∠13 = 38°, ∠14 = 142°, ∠15 = 38°, and ∠16 = 142°
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
The type of angles is given below.
Two angles are said to be supplementary angles if their sum is 180 degrees.If two lines are parallel then the third line. The corresponding angles are equal angles.When two lines intersect, then their opposite angles are equal.The measure of angle 7 is 38°. Angles 7 and 8 are supplementary angles.
∠7 + ∠8 = 180°
38° + ∠8 = 180°
∠8 = 142°
The measure of angle 10 is 102°. Angles 9 and 10 are supplementary angles.
∠9 + ∠10 = 180°
102° + ∠9 = 180°
∠9 = 78°
Then the measure of the remaining angles will be
∠1 = 78°
∠2 = 102°
∠3 = 78°
∠4 = 102°
∠5 = 38°
∠6 = 142°
∠7 = 38°
∠8 = 142°
∠9 = 78°
∠10 = 102°
∠11 = 78°
∠12 = 102°
∠13 = 38°
∠14 = 142°
∠15 = 38°
∠16 = 142°

how many serving were in the Container?
...................15?
====================================================
Explanation:
5 & 1/3 is the mixed number with 5 as the whole part and 1/3 as the fractional part
Let's convert to an improper fraction
5 & 1/3 = 5 + 1/3
5 & 1/3 = 5*(3/3) + 1/3
5 & 1/3 = 15/3 + 1/3
5 & 1/3 = (15+1)/3
5 & 1/3 = 16/13
The mixed number 5 & 1/3 is equivalent to the improper fraction 16/3
-------------------
Each serving is 7/8 cup
x of these servings is (7/8)x
x is the number of servings in a full container, so
(7/8)x = 16/3
x = (16/3)*(8/7)
x = (16*8)/(3*7)
x = 128/21
x = 6.0952 approximately
x = 6 when rounding to the nearest whole number
So the container is about 6 servings.

What is tje equation of the function?
Answer:
It is relatively easy to determine whether an equation is a function by solving for y. When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x.

The length y of a rectangle is four less than three times the width x. The perimeter of the rectangle is 16 cm.
Answer:
y = 1 cm
x = 7 cm
Step-by-step explanation:
x = 3y + 4
perimeter = 2 * ( y + x ) = 16
x + y = 8 by using x = 3y + 4
y + 3y + 4 = 8
4y = 4
y = 1
1 + x = 8
x = 7
y = 1 cm
x = 7 cm
Pentagon ABCDE and Pentagon A''B''C'D''E are shown on the coordinate plane below.
which two transformations are applied to Pentagon ABCDE to create A"B"C"D"E"?
A) Translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the y-axis
B) Translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the x-axis
C) Translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the y-axis
D) Translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis
Answer:
D) Translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.
If a point X(x, y) is translated a units right and b units down, it new location is X'(x + a, y + b)
If a point X(x, y) is reflected across x axis, it new location is X'(x, -y)
Pentagon ABCDE is at A(-4, 5), B(-6, 4), C(-5, 1), D(-2, 2), E(-2, 4) while pentagon A"B"C"D"E" is at A"(4, -7), B"(2, -6), C"(3, -3), D"(6, -4), E"(6, -6)
If pentagon ABCDE is Translated according to the rule (x, y) → (x + 8, y + 2), the new points would be A'(4, 7), B'(2, 6), C'(3, 3), D'(6, 4), E'(6, 6). If a reflection across the x axis is the done, the new points are A"(4, -7), B"(2, -6), C"(3, -3), D"(6, -4), E"(6, -6)
