Part AEstimate 10/12 - 3/8 using benchmark values. Your equation must show the estimate for each fraction and the final estimate
ser-zykov [4K]

ANSWER

\text{The final estimate for the expression is }\frac{11}{24}

STEP-BY-STEP EXPLANATION

Given information

\text{Estimate }\frac{10}{12}\text{ - }\frac{3}{8}

To estimate the above expression, we need to find the factors of the denominators to get the LCM

Factors of 12 = 2 x 2 x 3

Factors of 8 = 2 x 2 x 2

From the above factors, the LCM is 2 x 2 x 2 x 3 = 24

Therefore, LCM is 24

\begin{gathered} \frac{\frac{10}{12}\text{ - }\frac{3}{8}}{24} \\  \\ =\text{ }\frac{\text{ 24(}\frac{10}{12})\text{ - 24(}\frac{3}{8})}{24} \\  \\ =\text{ }\frac{2(10)\text{ - 3(3)}}{24} \\ =\frac{20\text{ - 9}}{24} \\ =\text{ }\frac{11}{24} \end{gathered}

The class president collected data on 150 randomly selected 17-year-olds at his school. He surveyed students on if they had a jo
telo118 [61]

Answer:

Step-by-step explanation:

Part A can be seen in the attached picture below. Since there are 76 students that have both a license and a job we need to subtract 76 from each to get the amount that only have either a license or a job as seen in the table. Also we can see from the table that it sums up to 145 students, meaning that 5 students do not have neither a job or a license.

Part B, to calculate this we need to divide the amount of students that ONLY have a job by the total amount of students that have a job (since the rest of those students also have a license) Therefore:

17 / 93 = 0.1828

Now we can multiply this result by 100 to get the percentage.

0.1828 * 100 = 18.28%

The diagram shows a sketch of a survey done by a civil engineering student .Find the value of x,giving your answer correct to 1
Hatshy [7]

You can do this by drawing one line through parallel to PQS to meet RQ at T

Now calculate length of RT:-

cos 70 = RT / 70 giving RT = 23.94m

sin 70 = ST/70 giving ST = 65.78 m

draw a line from S perpendicular to PQ to meet PQ at U.

PU = 110 - 65.78 = 44.22 m

tan 50 = SU / 44.22 giving SU = 52.70 m

TQ = SU = 52.70 m

So x = TQ + RT = 52.70 + 23.94 = 76.6 m to 1 dec place.
