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)

Therefore, Area(PQT) = Area(PST) by RHS congruency

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.

Answer: 1 1/2 in a hour

Step-by-step explanation:

1/2 every 1/3 so if we add one more half it is 1 and 2/3 the last one is 1 1/2 is 1 full hour.

The difference between the areas of the posters is 56 in².

There 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.

         A=(13 in)²

         A= 169 in²

         A=(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

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.

Therefore,

Answer:

Step-by-step explanation:

Supposing:

Coloured marbles = x

Glass marbles = y

According to Question

x = 3y

As,

x + y = 60

3y + y = 60 (putting value of x = 3y)

4y = 60

y = 60/4

y = 15

Hence, Leo has 15 Clear-glass marbles

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

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

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

The speed for maximum car mileage will be 48 mph. The maximum gas mileage will be 29.5 mpg.

We are provided with an equation for mileage of car as

m(x) =  -0.028x² + 2.688x  -35.012

here , variable 'x' is the speed of the car.

Now

for the maximum speed of the car we have to first take the derivative of m(x) and then for the boundary value condition by  putting the derivative equal to zero.

comparing to the equation  ax² + bx + c , if the value of

'a' is positive, then we have minimum value at 1st derivative = 0

'a' is negative we have maximum value .

in this case a = -0.028 ( -ve) so we will have a maxima at 1st derivative.

so, dm/dx = -0.056x + 2.688

putting the 1st derivative = 0 , we have

x = 48

therefore , car gets maximum gas mileage at speed of 48 mph.

Also , putting this value in equation (1) we will get max. mileage.

so max. mileage = -0.028 (48)² + 2.688 x 48 - 35.012

                           = -64.512 + 129.024 - 35.012

                           = 29.5

so the maximum gas mileage will be 29.5 mpg .

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
