HELP MEE!!!! Are the triangles at right congruent? If so, describe a series of rigid transformations that maps one triangle onto the other?
Answer:
No
Step-by-step explanation:
The missing angle of the 90-55-x triangle is 180-90-55=90-55=35
The missing angle of the 90-35-x triangle is 180-90-35=90-35=55.
Because both triangle have angles 90º, 55º, and 35º, they should be congruent, right?

The center of a circle is located at (2, 3) and has a radius of 6 units. Which equation represents this circle?
A- (x - 2)2 + (y - 3)2 = 6
B-(x - 2)2 + (y - 3)2 = 36
C- (x + 2)2 + (y + 3)2 = 36
D- (x + 2)2 + (y + 3)2 = 6
By using the general equation for a circle, we will see that the correct option is:
(x - 2)^2 + (y - 3)^2 = 36
How to find the equation for a circle?
The general equation for a circle centered at the point (a, b) of radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
In this case, the center is (2, 3) and the radius is R = 6 units, replacing that in the above equation we get:
(x - 2)^2 + (y - 3)^2 = 6^2
(x - 2)^2 + (y - 3)^2 = 36
So the correct option is B.

Student Council is selling t-shirts and hats for $15 and $12, respectively. The club needs to raise at least $1980. They have received pre-sale orders of 80 t-shirts and 20 hats. Graph a system of linear inequalities that shows the number of t-shirts and hats they must sell in order to reach their goal. Use x for the number of t-shirts and y for the number of hats.
Answer:
the possible combinations are (86,98) and (160,39)
The possible combinations are (86,98) and (160,39)
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Student Council is selling t-shirts and hats for $15 and $12, respectively.
let number of t- shirts sold be x and number of hats be y.
So, 15x+ 12y ≥ 1980
From the graph the inequality gives
x= 130 and y= 165.
Hence, 130 t shirts and 165 hats must be sold.

Step-by-step explanation:
Hey there! To find the 20th term of arithmetic sequence, we can do by using general terms.
General Term - Arithmetic
[tex]\displaystyle \large{a_n = a_1 + (n-1)d}[/tex]
where a_n is nth term, a_1 is the first term and d is our common difference.
We know the first term which is 12 and we want to find the 20th term which is our desired term.
Hence, the equation is [tex]\displaystyle \large{a_{20} = 12+(20-1)d}[/tex]
However, we don’t know the value of d yet which is common difference. To find the common difference, we can do by subtracting next term with previous term.
15-12 = 3
18-15 = 3
21-18 = 3
If we keep doing it, we’ll always get 3. Therefore, 3 is our common difference.
[tex]\displaystyle \large{a_{20}=12+(19)3}\\\displaystyle \large{a_{20}=12+57}\\\displaystyle \large{a_{20}=69}[/tex]
Thus, the 20th term is 69.

Answer:
la altura es irracional, y se multiplica por las otras dimensiones racionales.
Step-by-step explanation:
Dado que un trapezoide tiene bases de 3,6 cm y 12 1/3 cm.
Pero la altura es irracional como raíz cuadrada de 5 cm.
El área del trapezoide es irracional porque se encuentra agregando las dos bases y multiplicando por la mitad de la altura.
La suma de las bases sería racional, siendo la suma de dos números racionales
Pero como la altura es irracional, el área sería el producto de una

What is the average of 237, 482, 375, and 210?
The answer to the question is 326.
(237+482+375+210) ÷ 4

so, again, the average or mean value is created by adding up all values and then dividing that by the number of values.
we have 4 values here.
they add up to

Find the values of the variables. then find the side lengths of the square.
x = 2, y = 9, and the side length of the square is 6 units.
What is a Square?A square is a quadrilateral that has four equal lengths, that is, all its sides are equal.
Thus:
y - 6 = 2y - 15
Combine like termsy - 2y = 6 - 15
-y = -9
y = 9
Also:
3x - 3 = y - 6
Plug in the value of y3x - 3 = 9 - 6
3x - 3 = 3
3x = 3 + 3
3x = 6
x = 2
Therefore, the sides would be:
y - 6 = 9 - 6 = 3 units
In summary, x = 2, y = 9, and the side length of the square is 6 units.

One method which I find easier is converting both into fractions.
8/9 = 8/9 , and 0.9 = 9/10
Now, you have to find the least common denominator, which is 90 (9*10)
Now you have 80/90 and 81/90.
You have finished 80/90.
Your friend has finished 81/90.
81/90 > 80/90 so your friend is correct, they have done more of their project.

You mix 2/3 quart of blue paint for every 3/4 quart of red paint to make 4 quarts of purple paint. How
much blue paint and How much red paint do you use?
Answer:
1.8828 quarts of blue paint
2.1172 quarts of red paint
(check the explanation for more round off variations)
Step-by-step explanation:
Convert both fractions to decimals
[tex]\frac{2}{3}[/tex] = 0.667
[tex]\frac{3}{4}[/tex] = 0.75
Then turn the decimals to percentages
66.7%
75%
Then rewrite it as a fraction to find the missing percentages
75% : 1.417 = x : 1
Solve for x
x = 52.93
Then do this again for 66.7%
66.7% : 1.417 = x : 1
Solve for x
x = 47.07
Then find the values of these percentages relating to 1
47.07% of 1 is 0.4707
52.93% of 1 is 0.5293
Now we have how much blue paint and red paint is in each quart of purple paint
Multiply them by 4 to get the total
0.4707 x 4 = 1.8828
0.5293 x 4 = 2.1172
Now we have:
1.8828 quarts of blue paint
2.1172 quarts of red paint
Now if you want it to be rounded off to the nearest tenths or hundredths
1.8828 = 1.9 (hundredths = 1.88)
2.1172 = 2.1 (hundredths = 2.12)
