By taking a product, we can see that the total energy consumed by the console is 42,504 watt-hours.
How many watt-hours of energy the console used?Here we know that the console uses 154 watt-hours of energy each hour.
So, if you use it for x hours, the energy consumed is given by the product:
E = ( 154 watt-hours)*x
In this case, we know that the console is used for 276 hours, then we can write:
E = (154 watt-hours)*276 = 42,504 watt-hours.
Which is the product between the hourly consumption and the number of hours used.

A painting in the shape of a rectangle has side lengths of 30 inches and
21 inches. You buy a print of the painting with side lengths of 10 inches and
7 inches. Is the print similar to the original painting? Explain your reasoning
Answer:
Yes! The painting is similar.
Step-by-step explanation:
The sides of the original painting are 30 and 21. If you divide this by 3, it equals 10 and 7 which are the sides of the print. This means that the ratio is right so the paintings are similar.

He number of nano-related patents that are granted in the us increases by a factor of 1.21.21, point, 2 every year. in 199119911991, there were 606060 nano-related patents. which expression gives the number of patents in 199819981998?
The exponential function y = 60(1.2)7 yields the number of patents in 1998.
The formula for an exponential function is f (x) = ax, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis. Let y be the number of nanotechnology-related patents issued in the US in year x following 1991.
There were 60 patents on nanotechnology in 1991, and since then there has been a factor of 1.2 increase.
y = 60(1.2)ˣ
y = 60 in 1998 (7 years ago) (1.2)⁷
The exponential function is used to calculate the number of patents in 1998.
y=60(1.2)⁷

Evaluate. Write your answer as a whole number or as a simplified fraction.
x^2 - xy = 14
y^2 +xy = 60
The answer is
x = 7, -7, √2, -√2
Add the two equations to get
x2 + y2 = 74
Eliminate y from the first by solving for y and using that result:
(x2 − 14) = x√74 - x2
square both sides, then condense:
x4 − 51x2 + 98 = 0
These ready factors:
(x−7)(x+7)(x−√2)(x+√2)=0
I'll let you handle it from there, but keep in mind that if we square all sides, we might find roots that need to be pulled out afterward.

three friends ate at a restaurant. they ordered nachos for $19.95 and jalapeno poppers. each friend paid $9.73, not including sales tax or tip, which was one third of the total. determine the cost of the jalapeno poppers. $6.65 $9.24 $18.48 $29.19
The cost of the jalapeno poppers was $9.24 if each friend paid $9.73.
The cost of the jalapeno poppers can be determined by using multiplication followed by subtraction.
First, we determine the total amount paid by the three friends;
If each friend paid $9.73, then;
Total amount = 9.73 × 3
Total amount = $29.19
Now to find the cost of jalapeno poppers, we subtract the cost of nachos from the total amount paid by the three friends;
cost of jalapeno poppers = total amount - cost of nachos
cost of jalapeno poppers = 29.19 - 19.95
cost of jalapeno poppers = $9.24
Therefore, the cost of jalapeno poppers is calculated to be $9.24.

Nura made a square poster with a side length of 13 inches. Latrice made a square poster with a side length of 15 inches. Whats the difference in square inches between the area of Latrice's poster and the area of Nura's poster?
The difference between the areas of the posters is 56 in².
QuadrilateralsThere are different quadrilaterals, for example: square, rectangle, rhombus, trapezoid, and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, in a square, all angles are 90° and all sides present the same value.
The area of a square is given by: A= a², where a=the length of the side.
Area of square poster's NuraA=(13 in)²
A= 169 in²
Area of square poster's LatriceA=(15 in)²
A= 225 in²
Therefore, the difference in square inches between the area of Latrice's poster and the area of Nura's poster is 225 - 169=56 in²

Below are ten scores for two different students. Students have a choice: they can take the median of their scores as their final grade, or they can take the mean of their scores as a final grade. Scores are rounded to the nearest whole number. For each student tell which option would result in the highest grade.
Student A: 25, 78, 80, 82, 85, 86, 88, 89, 96, 99
Student B: 71, 77, 77, 79, 79, 80, 88, 89, 91, 96
Find the median and mean for both students.
Answer:
Step-by-step explanation:
Student A:
Mean 80.8
Median: 85.5
The Median is a higher score.
Student B:
Mean 82.7
Median: 79.5
Mean is a higher score
Answer:
Student A's median and Student B's mean would result in the highest grade.
Step-by-step explanation:
How to find the mean:
The mean is the average.
Therefore, you must add all numbers listed, then divide the added numbers by the amount of numbers you added together. Lastly, as instructed round to the nearest whole number.
- Student A : Mean = 81
Step 1 : 25+78+80+82+85+86+88+89+96+99 = 808
Step 2: 808 ÷ 10 = 80.8
Step 3: 80.8 ---> 81
- Student B: Mean = 83
Step 1: 71+77+77+79+79+80+88+89+91+96 = 827
Step 2: 827 ÷ 10 = 82.7
Step 3: 82.7 ---> 83
How to find the median:
The median is the middle number in a sorted list of numbers.
Therefore, you list all of the numbers from least to greatest. Then, you get rid of a number from each side until you finally get to the center number. If there are two numbers left in the center you then find the mean(average) of those numbers.
- Student A: Median = 86
Step 1: Knock off a number from each side until you reach the center number(s)
25, 78, 80, 82, 85, 86, 88, 89, 96, 99 ---> 85, 86
Step 2: Find the mean(average) of the two central numbers
85 + 86 = 171 ---> 171 ÷ 2 = 85.5
Step 3: Round your answer
85.5 ---> 86
- Student B: Median = 80
Step1: Knock off a number from each side until you reach the center number(s)
71, 77, 77, 79, 79, 80, 88, 89, 91, 96 ---> 79, 80
Step 2: Find the mean(average) of the two central numbers
79 + 80 ---> 159 ÷ 2 = 79.5
Step 3: Round your answer
79.5 ---> 80

(1) PQRS is a rhombus. Prove that APQT = APST by using all four conditions of congruency.
Four conditions of congruency are: SSS, ASA, SAS, RHS
Using SSS congruency,
Side: PS = PQ (by the rule, all sides of rhombus are equal)
Side: ST = TQ (by the rule, diagonals bisect each other)
Side: PT = PT (common)
Therefore, Area(PQT) = Area(PST) by SSS congruency
Using ASA congruency,
Angle: ∠TPS = ∠TPQ (diagonals bisect the angles)
Side: PS = PQ (by the rule, all sides of rhombus are equal)
Angle: ∠PST = ∠PQT (opposite angles are equal, and diagonals bisect the angles)
Therefore, Area(PQT) = Area(PST) by ASA congruency
Using SAS congruency,
Side: ST = TQ (by the rule, diagonals bisect each other)
Angle: ∠PTS = ∠PTQ (by the rule, diagonals bisect each other at 90°)
Side: PT = PT (common)
Therefore, Area(PQT) = Area(PST) by SAS congruency.
Using RHS congruency,
Right angle: ∠PTS = ∠PTQ (diagonals bisect each other at 90°)
Hypotenuse: PS = PQ (all sides of rhombus are equal)
Corresponding Side: ST = TQ (by the rule, diagonals bisect each other)

Perpendicular to y=-5x+1 passing through (2,-1)
The equation of the line perpendicular to the given line will be equal to 5y = x - 3.
A line may be defined as a straight figure which is drawn and has no end points. The equation of line in slope intercept form may be written as y = mx + c where m is the slope and c is the y intercept. The equation of line passing through a point (x₁, y₂) will be given as (y - y₁) = m(x - x₁). The slope of line perpendicular to a line having slope m is given by -1/m. The equation of line in the question is y = -5x + 1. The slope of the line is -5. The slope of line perpendicular to this line is 1/5. Equation of line passing through (2, -1) and slope 1/5 is given by

Write the quadratic function [tex]f(x)=\frac{1}{7} (x^{2} +14x+35)[/tex] in standard form and use it to find the axis of symmetry and the vertex.
Answer:
f(x) = 1/7 * (x + 7)^2 - 2
axis of symmetry: x = -7
vertex: (-7 | -2)
Step-by-step explanation:
f(x) = 1/7 * (x^2 + 14x + 35)
f(x) = 1/7 * (x^2 + 14x) + 5
f(x) = 1/7 * (x^2 + 14x + 7^2 - 7^2) + 5
f(x) = 1/7 * (x^2 + 14x + 7^2 - 49) + 5
f(x) = 1/7 * (x^2 + 14x + 7^2) + 5 - 7
f(x) = 1/7 * (x + 7)^2 + 5 - 7
f(x) = 1/7 * (x + 7)^2 - 2
