Answer:
a. Fraction of earnings that Mariano put into each piggy bank is 1/12
b. Mariano earns $28.8
Step-by-step explanation:
Mariano divides his earning in a saving account and 3 piggy banks.
First , we have to know the fraction that we divide in the 3 piggy banks.
Piggy banks =Total earning-Saving account
Saving account 3/4,
Total earning is 1
to rest both term we have to get the same denominator , so we can say that the total earning is 4/4
Piggy banks =4/4-3/4=( 4-3)/4=1/4
Piggy banks =1/4
Each piggy bank will be 1/3 of that 1/4
1/3 x 1/4=
For fraction multiplication, multiply the numerators and then multiply the denominators to get
1×1/3×4=1/12
This fraction cannot be reduced.
b. Mariano adds $2.40
1/12 is 2.40
total earning is ?
We use cross-multiplication
a/b=c/d replacing (1/12)/2.40 = 1/ ?
So, the total earning (?) is 1 x 2.40/ (1/12)
= 2.40 x 12=$28.8
Mariano puts 3/4 of his earnings in his savings account and divides the rest equally into 3 piggy banks. The fraction of his earnings that he puts into each piggy bank is (1/12)x dollars. Mariano earns 0 dollars per week delivering papers.
Explanation:To find the fraction of Mariano's earnings that he puts into each piggy bank, we need to calculate 3/4 of his earnings first. Let's assume he earns x dollars per week. Therefore, he puts 3/4 of x dollars into his savings account, which is (3/4)x dollars. The remaining (1/4)x dollars is divided equally into 3 piggy banks. So, each piggy bank gets (1/12)x dollars.
To find out how much Mariano earns per week delivering papers, we need to solve the equation (3/4)x + (1/12)x = x. Simplifying the equation, we get 9x/12 + x/12 = x. This is equivalent to (10/12)x = x. Multiplying both sides by 12, we get 10x = 12x. Subtracting 10x from both sides, we get 2x = 0. Therefore, x = 0.

Use the point-slope formula to write an equation of the line that passes through (-5,3) and
(4,6). Write the answer in slope-intercept form (if possible).
Answer:
The equation in point slope form is [tex]y-6=\frac{1}{3}(x-4)[/tex]
The equation in slope intercept form is [tex]y=\frac{1}{3}x-\frac{14}{3}[/tex]
Step-by-step explanation:
step 1
Find the slope m
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
[tex](-5,3),(4,6)[/tex]
Substitute the values
[tex]m=\frac{6-3}{4+5}[/tex]
[tex]m=\frac{3}{9}[/tex]
simplify
[tex]m=\frac{1}{3}[/tex]
step 2
Find the equation of the line in point slope form
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=\frac{1}{3}[/tex]
[tex](4,6)[/tex]
substitute
[tex]y-6=\frac{1}{3}(x-4)[/tex] ---> equation in point slope form
step 3
Find the equation of the line in slope intercept form
[tex]y=mx+b[/tex]
[tex]y-6=\frac{1}{3}(x-4)[/tex] ----> convert to slope intercept form
[tex]y-6=\frac{1}{3}x-\frac{4}{3}[/tex]
[tex]y=\frac{1}{3}x-\frac{4}{3}+6[/tex]
[tex]y=\frac{1}{3}x-\frac{14}{3}[/tex]
a fraction that is a repeating decimal between 0.5 and 1
The fraction [tex]\( \frac{2}{3} \)[/tex] results in a repeating decimal [tex]\( 0.\overline{6} \)[/tex], which falls between 0.5 and 1.
Sure, here's a step-by-step explanation:
1. Start with the fraction: We begin with the fraction [tex]\( \frac{2}{3} \)[/tex].
2. Convert to decimal: To convert this fraction to a decimal, divide the numerator (2) by the denominator (3).
[tex]\[ \frac{2}{3} = 0.66666... \][/tex]
The decimal representation of [tex]\( \frac{2}{3} \) is \( 0.\overline{6} \)[/tex], which means the digit 6 repeats infinitely.
3. Determine where it falls between 0.5 and 1: Since the decimal [tex]\( 0.\overline{6} \)[/tex] is greater than 0.5 and less than 1, the fraction [tex]\( \frac{2}{3} \)[/tex] indeed fits the criteria of being a fraction with a repeating decimal between 0.5 and 1.

Adhy, Ben and Clayson shared a bag of chocolates. The ratio of Adhy's share to Ben's share is 3:4 while
the ratio of Ben's share to Clayson's share is 3:5.
Given that Ben has 9 more chocolates than Adhy, find the difference between the number of chocolates
that Adhy and Clayson has.
Answer: 33
Step-by-step explanation:
The ratio of Adhy's to Ben's is 3:4 so let
Adhy = 3x
Ben = 4x
Since Ben = Adhy + 9
then 4x = 3x + 9
--> x = 9
So, Adhy = 3x = 3(9) = 27
Ben = 4x = 4(9) = 36
*************************************************************
The ratio of Ben's to Clayson's is 3:5
How do we get Ben's ratio of 3 equal to 36? by multiplying by 12
Ben : Clayson
3 x 12 5 x 12
36 60
So, Clayson = 60
***********************************************************
The difference between Adhy and Clayson is:
Clayson - Adhy

7X²-26X-8=0
Solving polynomial equations with factoring, algebra. Please help me!
Answer: [tex]\bold{x=\bigg\{4,-\dfrac{2}{7}}\bigg\}[/tex]
Step-by-step explanation:
7x² - 26x - 8 = 0
Find two numbers whose product equals (7)(-8) and sum equals -26.
-28 × 2 = 56, -28 + 2 = -26
Replace -26x with -28x + 2x: 7x² - 28x + 2x - 8 = 0
Factor the left two terms & right two terms: 7x(x - 4) + 2(x - 4) = 0
Notice that both sides have a common factor of (x - 4) --> This is one of the factors. The other factor is what is on the outside of (x - 4) --> 7x + 2
Rewrite the expression as two factors: (x - 4)(7x + 2) = 0
set each factor equal to zero and solve for x.
x - 4 = 0 7x + 2 = 0
x = 4 7x = -2

An airplane descended 4,000 feet before landing. The integer that represents how many feet the airplane was above the ground before it’s descent is ?
Answer:
Since, an airplane descended 4,000 feet before landing.
Now, we have to determine the integer which represents the number of feet, the airplane was above the ground before its descent.
Before the descent, airplane was at the height of 4,000 feet.
And the distance above the ground is represented by the positive integers and distance below the ground is represented by the negative integers.
Since, 4,000 feet is the distance of airplane above the ground.
So, the airplane was +4,000 feet above the ground before its descent.

For which of the following statements is the inverse false? A. If a triangle is an equilateral triangle, then one angle equals 60°. B. If a triangle is a right triangle, then the other two angles add up to 90°. C. If a triangle is an equilateral triangle, then each of the angles equals 60°. D. If a triangle is a right triangle, then one angle equals 90°.
The statement for which the inverse is false is A, because if one angle of a triangle equals 60°, the triangle is not necessarily equilateral.
The question asks for which statement the inverse is false. To answer this, we analyze each statement and its inverse:
A. If a triangle is an equilateral triangle, then one angle equals 60°. Inverse: If one angle of a triangle equals 60°, then the triangle is equilateral. This could be false if the triangle is not equilateral but one angle happens to be 60°.
B. If a triangle is a right triangle, then the other two angles add up to 90°. Inverse: If two angles of a triangle add up to 90°, then it is a right triangle. This is true, given the geometric principle that the sum of angles in a triangle is 180°.
C. If a triangle is an equilateral triangle, then each of the angles equals 60°. Inverse: If each angle of a triangle equals 60°, then it is an equilateral triangle. This is true, as by definition, an equilateral triangle has all angles equal.
D. If a triangle is a right triangle, then one angle equals 90°. Inverse: If one angle of a triangle equals 90°, then it is a right triangle. This is true, as by definition, a right triangle has one 90° angle.
Therefore, the statement for which the inverse could be false is A.
Evaluate f(x) = -4x + 7 when x = 2 and x = -2.
Answer:
f(x)=-1 and 15
Step-by-step explanation:
What you do is you put -2 and 2 into the x.
f(x) = -4(-2) + 7 = -1
f(x) = -4(2) + 7 = 15
f(x)=-1 and 15 are your answers.
After substituting the values of x into the function f(x)=-4x + 7, when x = 2 the result is -1, and when x= -2 the result is 15, indicating specific points on the graph of the function.
Explanation:To evaluate the function f(x) = -4x + 7 for specific values of x, we need to substitute the x values provided into the function.
When x = 2, f(2) = -4(2) + 7 = -8 + 7 = -1.
When x = -2, f(-2) = -4(-2) + 7 = 8 + 7 = 15.
So, f(2) = -1 and f(-2) = 15. These values represent specific points on the graph of the function f(x) = -4x + 7.

The graph depicts a logistic growth model, signified by an S-shaped curve, which represents population growth that begins exponentially, slows as resources deplete, and stabilizes at the carrying capacity.
Explanation:
The graph you are referring to seems to describe a logistic growth model, which is characterized by an S-shaped curve. This type of growth is common in populations where initially there is exponential growth due to plenty of resources and few individuals. However, as the population increases, resources become limited, slowing the growth rate; eventually, the population size stabilizes at the carrying capacity of the environment. When categorizing the graph:
Initially, the growth is exponential.
Over time, as resources become scarce, the growth rate decreases.
Finally, growth becomes nearly zero as the population reaches the environment's carrying capacity.
At different time intervals, we can annotate changes in the growth rate:
During the first phase, growth rate increases linearly with the number of individuals (exponential growth).
During the second phase, the growth rate decreases in proportion to the square of the number of individuals.
In the third phase, when carrying capacity is reached, the rate of growth is zero (no net increase in population).
This can be contrasted with the exponential growth model which is represented by a J-shaped curve and shows unbounded growth over time.

The perimeter of a rectangle is 44 m. The length is 4 m more than the twice the
width. Find the dimensions.
Final answer:
The dimensions of the rectangle with a perimeter of 44 m, where the length is 4 m more than twice the width, are 6 m for the width and 16 m for the length.
Explanation:
The perimeter of a rectangle is given as 44 m, and the length (L) is said to be 4 m more than twice the width (W). To find the dimensions, we can set up the following equations based on the properties of a rectangle:
Perimeter P = 2(L + W)
L = 2W + 4
Since the perimeter is 44 m, we can substitute the length expression into the perimeter equation:
44 = 2((2W + 4) + W)
By solving this equation for width (W), we get:
44 = 2(3W + 4)
44 = 6W + 8
36 = 6W
W = 6 m
Now that we have the width, we can determine the length using the expression for L:
L = 2(6) + 4 = 16 m
Therefore, the final answer for the width is 6 m and the length is 16 m.
The base of a triangle exceeds the height by 3 feet. If the area is 350 square feet, find the length of the base and the height of the triangle.
Answer:

From the conditions given, we set up an equation (1/2) * (h + 3) * h = 350. By solving for h, we find the height of the triangle is 20 feet and the base, which is 3 feet more, is 23 feet.
Explanation:In this problem, we are given that the base of a triangle exceeds the height by 3 feet and the area of the triangle is 350 square feet. We need to use the formula for the area of a triangle, which is (1/2)bh, where b is the base and h is the height. We can set up an equation from the given conditions: (1/2) * (h + 3) * h = 350. Solving for h, we get h = 20 feet. Therefore, the base b = h + 3 = 20 + 3 = 23 feet. So, the height of the triangle is 20 feet and the base is 23 feet.
