Answer:
c. 52
Step-by-step explanation:
since that triangle QRE is a right angle triangle
therefore QE = root 5²_3² = 4 cm " pythagorean "
since triangle PQE is a right angle triangle
therefore PQ= root 4²+6²= 2 root 13 = root 52
Answer:
B
Step-by-step explanation:
Each histogram section represents all values from the left value, to the right value of each section (i.e the section after 10 represents all values from 10 to 20).
If we break all the weights into categories by this principle, with frequencies in parenthesis, we get;
0-10: (0)
10-20: (0)
20-30: 21, 24 (2)
30-40: (0)
40-50: 42, 47 (2)
50-60: 54, 56 (2)
60-70: 65 (1)
70-80: 72 (1)
80-90: 83, 86 (2)
90-100: (0)
with these numbers, we know for certain that the correct answer is B
7/10 is 17th term of sequence a₁₆ = 1/5, d= 1/2.
Given the 16th term and the common difference, we add the common difference from the 16th term to determine the 17th term:
a₁₇ = a₁₆ + d
= 1/5 + 1/2
= 7/10
<h3>How to solve an equation?</h3>
To solve linear equations, utilize the steps that are provided below.
- Remove parentheses from each side of the equation and combine similar terms to make it simpler.
- To separate the variable term on one side of the equation, use addition or subtraction.
- To find the variable, use division or multiplication.
- The common denominator can be multiplied by each side of the equation to eliminate fractions.
Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.
