A piece of string 85 cm is divided into three pieces in the ratio 2 : 3: 5. Calculate: i) shortest piece
Answer: 17 cm
Step-by-step explanation:
First step is to add up the numbers in the ratio:
= 2 + 3 + 5
= 10
The shortest piece according to the ratio is the 2 in the ratio. To find out the length this 2 corresponds with, use two as the numerator and 10 as the denominator:
= 2 / 10 * 85 cm
= 17 cm

The equation y = -20x + 275 represents the balance of Cassie's bank account y after x months. Which of the following statements regarding Cassie's account is not true?
The rate of change of the function is the slope of the line, -20.
The rate of change of the function is the slope of the line, -20.
The initial value of the function is the y-intercept of the line, 275.
The initial value of the function is the y-intercept of the line, 275.
Initially, Cassie has $20 in her account.
Initially, Cassie has $20 in her account.
Each month after the initial month, Cassie withdraws $20 from the account.
Please help
Answer: The answer that is false is “Initially, Cassie has $20 dollars in her account.”
Step-by-step explanation: The reason why this is false is because the first statement that the slope of the line is -20 is true. The formula for slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Next the initial value is 275 because in these problems the y-intercept is technically the starting value in these problems. So since the initial value is 275 the last statement is false.

Whats LN? *with picture*
Answer:
LN = 15 in
Step-by-step explanation:
We can say that arc PL plus arc LM is equal to arc PM:
arcPL + arcLM = arcPM
We can substitute what we have:
10 + 14 = arcPM
arcPM = 24.
Since both arcPM and arcLN equal 24, we can say they are congruent.
In circles, congruent arcs create congruent chords, so, we can say PM = LN.
Since PM is 15, LN = 15 in

Find the missing angle
Answer:
105
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to the exterior angle
25+80 = ?
105 = ?
Answer:
105
Step-by-step explanation:
The missing angle is supplementary to the missing inside angle of the triangle shown.
to find the missing angle in the triangle, set up your formula as
180=25+80+x
180-25-80=x
75=x
The missing angle is then 180-75=105

Andy estimated that he would need 73 feet of lumber for a tree house project. He later found that the actual amount of lumber needed was 62 feet. What was the percent error of Andy's estimation?
Answer:
17.74%
Step-by-step explanation:
The formula for percent error is given as:
|Estimated value - Actual value|/Actual value × 100
From the above question:
Estimated value = 73 feet
Actual value = 62 feet
Hence,
Percent error = |73 - 62|/62 × 100
= 11/62 × 100
= 17.741935484%
Approximately , percent error = 17.74%
Therefore, the percent error of Andy's estimation is 17.74%
