Hey there! :)
For this, you have to use the Pythagorean Theorem.
a² + b² = c² is the same as c² - a² = b²
c = 26
26² = 26 × 26 = 676
a = 10
10² = 10 × 10 = 100
676 - 100 = 576
√576 = 24
b = 24 cm
Hope this helps :)
Answer:
The annual rate of interest is 2.56%
Step-by-step explanation:
Given as :
Principal Amount investing every week = $25
Principal Amount investing in 5 years = $25 × 5 × 52 = p = $6500
The Amount adds after 5 years = A = $7380
Time period = t = 5 years
Let annual rate of interest = r %
<u>Now, According to question</u>
Amount after 5 years = Principal ×
Or, A = p ×
Or, $7380 = $6500 ×
Or, =
Or, 1.135 =
Or, = 1 +
Or, 1.0256 = 1 +
Or, 1.0256 - 1 =
Or, 0.0256 =
∴ r = 0.0256 × 100
i.e r = 2.56
So, The rate of interest = r = 2.56
Hence, The annual rate of interest is 2.56% Answer
17. The variable "a" represents the age of the child
18. The variable "A" represents the adult dosage
19. The prescribed dosage of the medicine for the 6-year-old child is 60 milligrams.
Work: C=6/(6+12)·180
C=6/(18)·180
C=60
Answer:
Ada is correct.
Step-by-step explanation:
Problems with Naman:
Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Division
Addition
Subtraction
~
The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.
Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.
