Are the triangles similar?
And why?
Answer:
No
Step-by-step explanation:
The first triangle is smaller and the second one is bigger. The first is 60 degrees and the second is about 89. (Maybe, ask your parents. I'm not quite sure of the angles.)
solve 2r+3<7 and -r+9≤2
Answer:
r<2
r greater than or equal to 7
Step-by-step explanation:
The solution for r in the two of the given inequalities is r<2 and r ≥ 7, respectively.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given inequalities can be solved as shown below.
1.)
2r + 3 < 7
Subtract 3 from both sides of the inequality,
2r + 3 - 3 < 7 - 3
2r < 4
Divide both the sides of the inequality by 2,
2r/2 < 4/2
r < 2
2.)
-r + 9 ≤ 2
Subtract 9 from both sides of the inequality,
-r + 9 - 9 ≤ 2 - 9
-r ≤ - 7
Multiply from both sides of the inequality by -1,
(-r × -1) ≤ (-7 × -1)
r ≥ 7
Hence, the solution for r in the two of the given inequalities is r<2 and r ≥ 7, respectively.

On his way to the office each workday (Monday through Friday), Darrell walks by a charitable foundation with a donation bucket set out front. He has decided that he nts to try to be more charitable, so starting next week, he plans to put $1 in donation bucket every day he walks by. He has also estimated that he has already donated $23 to the foundation, Part if x represents the number of weeks thłt Darrell has been making a donation, write a recursive function to represent the total amount he has donated Explain your work
Answerer: Darrell has already donated $23 to the foundation, so f (0) =$23.
Because x represents the number of weeks, and Darrell is contributing $1 every day, Monday through Friday, he will contribute a total of $5 per week. So, the total amount donated will increase by $5 each week. Therefore, the recursive function will be f (x) =f(x - 1) + $5, where f ($23).
The following are trinomial EXCEPT.

Two stores are having a sale on the
same dress. One store is offering
30% off the regular price of $82.40.
The other store is offering 20% off
the regular price of $63.60.
What is the difference between the
sales prices of the two stores?
DONT ANSWER IF U DONT KNOW.!
Answer:
6.8
Step-by-step explanation:
30% of 82.40 = 24.72
20% of 63.60 = 12.72
--------------------------------
82.40 - 24.72 = 57.68
63.60 - 12.72 = 50.88
57.68 - 50.88 = 6.8

Please answer! Will give brainiest! Which of the following side lengths could form a right triangle? Circle all that apply
A. 3, 7, 10 B. 4, 9, 10 C. 5, 12, 13 D. 6, 8, 10
Answer:
C. 5, 12 and 13
D. 6, 8 and 10
Step-by-step explanation:
To see if three side lengths would give you a right triangle, you have to use the Pythagoras Theorem which is a² + b² = c², where c is the hypotenuse (longest side) and a and b are adjacent to the right angle.
A. 3² + 7² ≠ 10²
9 + 49 ≠ 100
58 ≠ 100
B. 4² + 9² ≠ 10²
16 + 81 ≠ 100
97 ≠ 100
C. 5² + 12² = 13²
25 + 144 = 169
169 = 169
D. 6² + 8² = 10²
36 + 64 = 100
100 = 100
Find the equation of each line in slope intercept form , the slope is 5 and it goes through the point (2-1)
y - -5 = (5/2)(x - 3)
y + 5 = (5/2)x - 15/2
y = (5/2)x - 15/2 - 5
y = (5/2)x - 15/2 - 10/2
y = (5/2)x - 25/2
Answer:
y = 5x - 9
Step-by-step explanation:
point-slope equation:
y - y1 = m(x - x1)
y + 1 = 5(x - 2)
y + 1 = 5x - 10
- 1 - 1
y = 5x - 9
