Answer:
12s^2 - s - 20
Step-by-step explanation:
It's simplest form is when it's fully expanded.
To expand: (3s-4)(4s+5)
(3s * 4s) + (3s * 5) + (-4 * 4s) + (-4 * 5)
= 12s^2 + 15s -16s -20
= 12s^2 - s - 20
What is the probability of the spinner stop on an even number?
Answer:
Depends on what numbers are there.
Step-by-step explanation:
If the numbers are 0-10 then there is a 50% chance of the spinner stopping on an even number because there is 5 even numbers and 5 uneven numbers.
The probability of the spinner stopping on an even number will be equal to 5/10.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
The total number on the spinner is 10
The total even number on the spinner is 5.
Probability = 5/10
Therefore, The probability of the spinner stopping on an even number = 5/10

Respuesta: el deberá $8.43 de interés en un mes.
Explicación paso a paso:
Regla de 3
$562 -- 100%
x --- 18%
x = 101.16
$101.16 es la cantidad de intereses que deberá en un año, pero ¿en un mes?
Para saberlo solo lo dividimos entre la cantidad de meses en un año (12)
101.16 ÷ 12 = 8.43

a. Are triangles ABC and DEF similar?
Show or explain your reasoning.
Yes, the triangles are similar to each other by AA rule and EF = 8.
What is similarity in triangles?When two triangles have congruent corresponding angles and corresponding sides in equal ratio, then they are said to be similar.
Given are the triangles, Δ ABC and Δ DEF,
In Δ ABC,
∠A + ∠B + ∠C = 180°
∠B = 180°- (60°+20°)
∠B = 100°
In Δ DEF,
∠D + ∠E + ∠F = 180°
∠F = 180° - (60°+100°)
∠F = 20°
∠A ≅ ∠D
∠B ≅ ∠E
∠C ≅ ∠F
We see, all the corresponding angles are congruent.
Therefore, according to definition of similar triangles Δ ABC ~ Δ DEF,
And,
AB/DE = BC/EF = AC/DF = 3/4
BC/EF = 3/4
6/EF = 3/4
EF = 8
Hence, the triangles are similar to each other by AA rule and EF = 8.

Two sides of a rectangle are both 4 inches. If the
perimeter is 30 inches, write and solve a two-step
equation to find the missing lengths. Help
Answer: 2(4)+2b=30 /missing lenght=11
Step-by-step explanation: We know the equation of a rectangle is 2a+2b=perimeter "a" and "b" both represent a side length
2(4)+2b=30 <--- Plug in the know side lenght
8+2b=30
8(-8)+2b=30(-8) <--- Subtract "8" from both sides to further solve
2b=22
2b/2=22/2 <--- Divide each side by "2"
b=11

You have the beginning right.
However, it is X squared, so once you have the answer from adding the two fractions together, you have to Square Root that answer.
Answer:
x= √(10/25)
Step-by-step explanation:
From what you've written, you're on the right track. The formula is a^2+b^2=c^2. our two sides are a and b (doesn't really matter here which is which). And the hypotenuse, the longest leg the diagonal, is always c. Based on your substitution, everything is correct, except x. x should be squared. so the equation you should have is (1/5)^2 + (3/5)^2=x^2. From there, solve for x by adding a^2 and b^2 to get 10/25 = x^2.
Take the square root of each side to find √(10/25)=√(x^2). This is simplified as x equals plus or minus √(10/25). it's plus or minus because you took the square root. It's important to write that when solving square root. However, since this is a triangle your answer will be positive(you can't have negative distance).

Mr. Hudkins wants his 6th grade math class to memorize their multiplication facts. He decides to increase the number of facts they are expected to memorize each week and creates the following table.
Usingw = number of weeks and m = number of multiplication facts, which of the following equations is represented by the table Mr. Hudkins created?
A
m = 30 × 2w
B
m = 15 + w
C
w = 15m
D
m = 15w
Answer: m = 15w
Step-by-step explanation: The reason why the answer is m = 15w is because since he said "He decides to increase the number of facts they are expected to memorize each week." Which makes it so that only the multiplication fact increased to 15 since they wouldn't put it lower then that. And there is a 2nd reason why the multiplication fact is 15. the reason why is because theres only one answer with 30 and its completely wrong. So therefore,, The answer is Multiplication Fact = 15weeks.
Answer:
m = 15w

-2(x - 2) = -3 - 21 I need help with that question, I've been trying to solve it for hours but i cant find the answer
Answer:
x = 14
Step-by-step explanation:
you would first distribute the -2 with x - 2, which should give you -2x + 4, and you want to do the -3 - 21, which would give you -24, then subtract 4 from -2x + 4, then you should have -2x = -28, then divide it by -2, which should give you x = 14
Answer:
x = 14
Step-by-step explanation:
In this problem, we must isolate x
Given: -2(x - 2) = - 3 - 21Simplify the right side: -2(x - 2)= - 24Distribute the -2 to x and -2 (multiply): -2x + 4 = -24Subtract 4 from both sides: -2x = -28Divide both sides by -2: x = 14Two fifth grade classes are attending an amusement park as a field trip. Their teachers
purchased the tickets for the class and the parent chaperones. Mrs. Huffman purchased 25
child tickets and 30 adult tickets, which cost a total of $1,115. Mr. Snyder purchased 25 child
tickets and 2 adult tickets, paying a total of $471. What are the ticket prices?
The price of a child ticket is $
and the price of an adult ticket is $
Answer:
Price of child ticket: 17.
Price of adult ticket: 23
Step-by-step explanation:
25 times 17 equals 425.
1,115 minus 425 equals 690.
690 divided by 30 is 23.
425 plus the 2 adult tickets (23 plus 23 which is 46) would be 471, therefore 17 per child ticket and 23 per adult.

Step-by-step explanation:
A. $24.50 × 5 weeks = $122.5
- He only deposited one time each week so take the amount he puts in every week and multiply it by the amount of times he did it which is 5
B. $85.20 × 4 = $340.8
- 4 friends get the same amount of money just multiply that money amount they earned by all of them which is 4.
