Answer:
Isosceles Triangle; Acute Triangle
Step-by-step explanation:
Review your definitions of the different types of triangles:
acute triangle- a triangle that has three acute (less than 90 degrees) angles
obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.
right triangle- a triangle that had one right (90 degrees) angles
isosceles triangle- a triangle with two congruent sides and one unique side and angle.
equilateral triangle- a triangle with three congruent sides and three congruent angles.
scalene triangle- a triangle with no congruent sides and no congruent angles.
With these definitions, we can classify ΔPQR as an isosceles acute triangle.

Step-by-step explanation:
George is 31 years older than Leo who is 15 years younger than Carol. In how many years will Carol be the same age as George is now?
Answer:
16 years
Step-by-step explanation:
Break the problem down:
George = 31 + Leo
Leo = Carol - 15
Carol = ?
The problem is asking for the number of years it will take for Carol to be George's current age.
Leo is 15 years younger than Carol which means Carol is 15 years older than Leo.
George is 31 years older than Leo. Carol is older than Leo by 15 years.
This means we have to find the difference between 31 and 15.
31 - 15 = 16
Since the difference between George and Carol's age is 16 years, it will take Carol 16 years to be the same age as George is now.

Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15
Answer:
Roots are : 1, -7 and -7
Step-by-step explanation:
When we put x = -1 in F(x) it is equal to 0
Thus, (x + 1) is factor of given function.
When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)
factorizing the work x² - 6x - 7 by middle term splitting.
> x² - 6x - 7 = x² - 7x + x - 7
> x(x - 7) + 1(x - 7)
> (x + 1) (x - 7)
then, x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)
x = -1, -1, 7 the factor.

1. 57 is the constant rate of change
2. The ratio for Ms. Bojorquez is 32:28 which simplified is 8:7. The ratio for Ms. William is 104:98 which simplified is 52:49. So they are not equivalent ratios.
3. No, it will take almost 10 minutes.

The average cost of Purell in 2019 was $8.99 for a bottle. In 2020, the cost of Purell on Amazon jumped to $58.99. What is the percent change? Round to the nearest tenth of a percent.
Answer:
556.2% change
Step-by-step explanation:
Percentage change = (p2-p1)/p1 * 100%
= (58.99 - 8.99) / 8.99 * 100%
= 556.2% change

Use the given line of best fit to approximate the rate of change relative to the scatter plot below.
A. 1/20 errors per word translated
B. 1/5 errors per word translated
C. 1/10 errors per word translated
D. 3/20 errors per word translated
Answer:
C. 1/10 errors per word translated
Step-by-step explanation:
According to this graph, we can see that every 100 words-translated, there are about 10 errors (red line). The red line continues at this slope/ratio, and so it would be 10/100 or 1/10 simplified.
The rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
For the given condition, we have to find the rate of change relative to the scatters plot below.
The given graph is in between the total error and the translation error. This graph shows that there are around 10 translation mistakes for every 100 words (red line). Given that the red line continues at this slope and ratio, it would be expressed as 10/100 or 1/10.
Thus, the rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.

y/x = 8
Show wether x and y show direct variation
Help I don’t wanna go to summer school
Answer:
y/x = 8 shows DIRECT variation.
Step-by-step explanation:
y varies directly as x if y = kx for some constant, k. In other words, y/x is constant.
help me plsssssssss!!
Answer:
y= -5x/-4 - 3
Step-by-step explanation:
The first thing you need to do is write down the problem 5x-4y=12.
You will then want to solve as shown below:
5x-4y=12
-4y=-5x+12 you want to isolate the y value
-4y/-4=-5x/-4+12/-4 you want to divide everything by negative 4
y= -5x/-4 - 3 you wan to clean your eqution up
