Answer:

The percentage error of measurement is 5.63 %

Step-by-step explanation:

Given as :

The measure length of the fence = 150 feet

The actual length of the fence = 142 feet

Let the percentage error in measurement = x

So, x = $\dfrac{\textrm measured value - \textrm actual value}{\textrm actual value}$ ×100

Or, x = $\dfrac{\textrm 150 - 142}{142}$ ×100

or, x = $\dfrac{\textrm 8}{142}$ ×100

or, x = 5.63 %

Hence The percentage error of measurement is 5.63 % Answer

liq [111]

Answer:

$8\frac{1}{2}$ cups

Step-by-step explanation:

To determine the quantity of snack mix Jared guest ate, we multiply the quantity of snack mix the guest ate by the quantity of snack mix Jared made. i.e we determine $\frac{2}{3}of12\frac{3}{4}$ by multiplying both fractions together

quantity of snack mix Jared guest ate = $\frac{2}{3}of12\frac{3}{4}=\frac{2}{3}*12\frac{3}{4}=\frac{2}{3}*\frac{51}{4}=\frac{17}{2} =8\frac{1}{2}$

During the summer, the height of the water in the pool decreased by 5 inches each week due to evaporation. What is the change in

rjkz [21]

Answer:

40 inches

Step-by-step explanation:

We know that the height of water in a pool decreased 5 inches per week.

This means that we can form the equation $y=-5x$ , since the amount of water remaining is proportionate to the amount of weeks that have passed.

We know $x=8$ , since we need to find the change for 8 weeks.

$y = -5\cdot 8$

$-5 \cdot 8 = -40$

$y=-40$

The change will be the absolute value of -40, which just makes it positive, so 40.

Hope this helped!

5 % of what number is 12

allochka39001 [22]

Answer: 240

Step-by-step explanation:

Let the missing number be represented by p

5% of p = 12, where 5% = 5/100

Therefore, we can rewrite the expression as:

5/100 x p = 12

= 0.05p = 12

Divide both sides by 0.05 to get the value of p

0.05p/0.05 = 12/0.05

p = 240

Therefore, 5% of 240 = 12

Helga [31]

The cost of each t-shirt is <u>$7</u>, using the equation formed from the given conditions.

In the question, we are given that the drama club is printing t-shirts for its members. The printing company charges a certain amount for each shirt plus a setup fee of $40.

We are aske to find the cost of each t-shirt if there are 21 students in the club and the t-shirt order costs a total of $187.

We assume the cost of one t-shirt to be $x.

Thus, the cost of printing 21 t-shirts = $21x.

The setup fee is given to be $40.

Thus, the total cost of printing 21 t-shirts for the dram club = $21x + 40.

But, we are given that the total cost is $187.

Thus, we get an equation,

21x + 40 = 187.

This equation can be solved as follows:

21x + 40 = 187,

or, 21x = 187 - 40,

or, 21x = 147,

or, x = 147/21,

or, x = 7.

Thus, the cost of each t-shirt is <u>$7</u>, using the equation formed from the given conditions.
