Answer: The total volume of all the tanks at the aquarium after the new dolphin tank is installed will be 1.25x10^6 gallons + 250,000 gallons = 1.5x10^6 gallons.

This is the equivalent of 1,500,000 gallons.

Step-by-step explanation:

The original cardboard measures 25 cm by 40 cm. By cutting out a 10 cm by 10 cm corner square, the new measurement of the cardboard will be 15 cm by 30 cm. The volume of the container will be 4500 cm^3.

The goal of this project is to build a container out of a rectangular piece of cardboard measuring 25 cm by 40 cm. To do this, a square must be cut out of each corner of the cardboard and the sides must then be bent up. In order to produce a container with the most internal volume, the corner square should be 10 cm by 10 cm. This will result in four equal sides and a larger internal volume. The larger internal volume will allow the container to hold more material, thus making it more efficient for the project.

The unit rate of cup of powered mix per gallon for each person by

Maria: 3 cups

Franco: 1/3 cups

Rate of powdered mix = number of cups ÷ number of gallons of water

Keep the values in formula to find the unit rate of cup of powdered mix

Rate of powdered mix by Maria = (3/4)÷3

Rate of powdered mix by Maria = 3/(4×3)

Cancelling 3 as it is common

Rate of powdered mix by Maria = 3 cups per gallon

Firstly converting the amount of cups from mixed fraction to fraction

Amount of cups = 1 [tex] \frac{2}{3} [/tex]

Amount of cups = 5/3 cups

Rate of powdered mix by Franco = (5/3)÷5

Rate of powdered mix by Franco = 5/(5×3)

The set of all possible y-x values is between 3 and 6, excluding both endpoints.

===================================================

Explanation:

The y-x value is smallest when:

I recommend to draw out a number line. The idea is to place x and y as close as possible to each other.

Based on those two conditions, we use y = 10 and x = 7 respectively. That gives y-x = 10-7 = 3 as the smallest possible difference. Keep in mind we can't actually reach this value so we would write y-x > 3 which is the same as 3 < y-x.

--------------------

Similarly, y-x is largest when:

Like earlier, use a number line to see why this would be the case. We're trying to space x and y out as far as possible.

The largest y value and smallest x value are y = 12 and x = 6 in that order. So the upper bound is y-x = 12-6 = 6. Like before, we can't actually reach this number which means we write y-x < 6.

--------------------

Recap:

Put those two results together in a tidy compound inequality to get the final answer    3 < y-x < 6

It says: The expression y-x is between 3 and 6, excluding both endpoints.

A mathematical function called a probability distribution explains the likelihood of many alternative values for a variable. Graphs or probability tables are frequently used to represent probability distributions. The probability distribution of X is defined as the function f(x) p(x)= P(X=x) for any x falling within the range of X. The probability mass function for the discrete random variable X is another name for it.

A unique type of normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution, or z-distribution. By transforming the values of any normal distribution into z scores, it is possible to standardize it. Z scores provide the number of standard deviations from the mean that each value falls within.

The value that Helen wants to use is Pi = C/D. The lower bound value is 3.065, and the upper bound for Helen's value is 3.165.

What is circumference?

The circumference is the perimeter of the circle.

Given, the circumference, C, at 405 mm to three significant numbers.

She correctly estimates the diameter, d, to be 130 mm to two significant numbers.

Helen wants to find the value of Pi using the formula pi=C/D

We have, the circumference of the circle = C = 405 mm

The diameter of the circle = d = 130 mm

Pi = C/D

= 405 mm / 130 mm

= 405 / 130

= 3.115

3.115, measured to the nearest 0.1.

The degree of accuracy is nearest 0.1.

0.1/2 = 0.05

Upper bound = 3.115 + 0.05 = 3.165

Lower bound = 3.115 - 0.05 = 3.065

Therefore, the lower bound and upper bound for Helen's value are 3.165, and 3.065.

Answer:

y = 3x + 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 2, - 2) ← 2 points on the line

m = [tex]\frac{-2-4}{-2-0}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3

the line crosses the y- axis at (0, 4 ) ⇒ c = 4

y = 3x + 4 ← equation of line

Answer:

y=3x+4

Step-by-step explanation:

The formula used is point slope, or y=mx+b

here, the m is the slope, and the b is the y-intercept

The y-intercept is where the graph crosses the y-axis, also known as when x=0

In this case, the y intercept is at the point (0,4) so you'd plug in 4 for the 'b' in the equation

To find the slope, use the rise over the run of the graph.

To do this, pick two points along the graph, and count how many units up/down, and to the left/right between the two points

The units up/down goes on top, being positive if they're up, and negative if they're down

The units left/right go on bottom, being positive if they're right, and negative if they're left

In this case you go 3 units up, and 1 unit right, so the slope would be 3/1 or 3

What the slope and the y-intercepts represent are;

Slope means that the rate at which the number of miles people in the U.S. traveled per year increased was 0.048

y-intercept means that the number of vehicle-miles traveled in 1975 is; 1.345 (in trillions)

A reasonable prediction for the number of miles people in the U.S. will travel in 2022 is; 3.601 (in trillions)

The equation for the line of best fit is given as;

y = 0.048x + 1.345

where;

x is the number of years since 1975

y is the number of vehicle-miles traveled in trillions

The equation of a line in slope intercept form has the general form as;

y = mx + c

where;

m is slope

c is y-intercept

Thus;

Slope = 0.048 which is the rate at which the number of miles people in the U.S. traveled per year increases.

y-intercept = 1.345 (in trillions) which is the number of vehicle-miles traveled in 1975

The year 2022 will be 47 years since 1975 and so the prediction is;

y = 0.048(47) + 1.345

y = 3.601 (in trillions)

The properties of the triangles created from the original triangle based on triangle congruency rules are as follows;

SSS: The triangle created using the lengths of the three sides of the original should have the same length and angles as the original

The triangle formed using SSS is a unique triangle and no other triangle has similar dimensions

SAS: The lengths of the sides and the measure of the angles should be the same

The triangle created using SAS is a unique triangle and there is not a way to have a third side that has a different length

ASA; The triangle formed using the ASA of the original triangle should have the same length as the same lengths and angles as the original triangle

The triangle formed using ASA is a unique triangle and there is not a way to create a triangle that has a different side length.

Two triangles are congruent if the lengths of the three sides of one triangle are congruent to the three sides of the other triangle or if they meet the other conditions of triangle congruency.

Length of first measured side of the triangle = 52 units

Angle made by the first measured side with the horizontal = 41°

Length of the second measured side of the triangle = 87 units

Angle the second measured side makes with the horizontal = 33°

Length of the third measured side of the triangle = 113 units

Angle the third side makes with the horizontal ≈ 6.5°

Let the vertices of the first side be A and B, we get;

∠A = 180° - (41° + 33°) = 106°

∠C = 33° - 6.5° = 26.5°

∠B = 41° + 6.5° = 47.5°

SSS: The SSS (Side-Side-Side) congruency postulate states that if the three sides of one triangle are congruent to the three sides of another triangle, then the two triangles are congruent.

Therefore, the lengths of the sides and the measures of the angles of the triangle created using the lengths of the three sides of the original triangle will be the same as the original triangle.

The SSS congruency postulate indicates that the triangle created using the same lengths of the three sides of the original triangle is a unique triangle and there are no other triangles having the same side lengths but different angles

SAS: The Side-Angle-Side, SAS, congruency postulate states that if the adjacent sides and an included angle of a triangle are congruent to two adjacent sides and an included angle of another triangle, then the two triangles are congruent.

Therefore, the triangle formed using two sides of the original triangle and the included angle between them will have the same length as the sides of the original triangle, and the triangle formed using the SAS of the original triangle is unique

The length of the third side of the triangle created using the SAS measurement is always the same as the length on the original triangle

ASA: The Angle-Side-Angle, ASA, congruency postulate states that if two angles and the included side of one triangle are congruent to two angles and an included side of another triangle, then the two triangles are congruent.

The triangle formed using the ASA is a unique triangles and therefore and there is no way to create a triangle that has a different side length
