The correct answers are B, D and E
Explanation:
The best way to find if each of the statmenet is true or false is to find the percentage in each case. To do this, follow this general formula: Total number / 100 (100 representes the total) x specific percentage. Now, let's apply this formula in each statement
A)
30 ÷ 100 = 0.3 x 15 = 4.5 (This statement is false)
B)
80 ÷ 100 = 0.8 x 25 = 20 (This statement is true)
C)
50 ÷ 100 = 0.5 x 30 = 15 (This statment is false)
D)
60 ÷ 100 = 0.6 x 30 = 18 (This statement is true)
E)
20 ÷ 100 = 0.2 x 40 = 8 (This statement is true)
Answer:
The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two.
Answer:
D) 4 E) 15 F) 30 G) 30 H) 70
Step-by-step explanation:
D) the square root of 4 is 2. We do 2 x 2 = 4.
E) the square root of 9 is 3. We do 3 x 5 = 15.
F) the square root of 25 is 5. We do 5 x 6 = 30.
G) the square root of 36 is 6. We do 6 x 5 = 30.
H) the square root of 100 is 10. We do 10 x 7 = 70.

Answer:
p = 200 - 35w
Step-by-step explanation:
Let's represent
Number of weeks = x
Amount of money Jane still owes her parents = p
From the above question, we are told:
Jane borrowed = $200
She agreed to pay = $35 each week. Therefore, the equation that represents the amount of money Jane still owes her parents, p, after w weeks is written as:
p = $200 - $35 × w
p = 200 - 35w
B or a because they are negative numbers
