Answer:
5.25 feets
Step-by-step explanation:
Given the question :
Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Length of one side of Square poster = 1 1/2 Feets = 3/2 feets
Length of wall = 12 feets long
Since Abdul wants the poster to be centered in the wall; then the picture should be placed such that there must be equal space left on either side of the wall after hanging.
Hence, (12/2 - 1 1/2) = (6 - 0.75) feets
= 5.25 feets
Distribute -3.2 through the parentheses
Cancel equal terms on both sides of the equation
Add the decimals
<em>Thus, The expression are equivalent at b = 9.12...~</em>
Answer:
a) 2.5 km
b) 1836 m ≈ 1.8 km (rounded)
Step-by-step explanation:
a) just add the two distances of the vertical and horizontal road. 900m + 1600m = 2500m = 2.5 km
b) Apply Pythagoras (a²+b²=c², where a and b are the vertical and horizontal roads, and c is the diagonal road).
c = √(1600²+900²) ≈ 1836m (rounded)
Using the 2x+2y=P formula, it equals 34
The percentage of students who spend less than 4 hours a week on screens which reported a grade average below 80 is 50%
Given, we have the report representing children spending time online, on social media or watching T.V, which has there effect on there grades as above or below 80.
By the question we know that the number of students who spends less than 4 hours a week on screen is:
9 + 9
= 18
And among the 18 students there are 9 students whose grade average is below 80.
So the percentage of the students who spends 4 hours a week on screen is:
= 9 ÷ 18 × 100%
= 100/2
= 50%
hence 50% students spend less than 4 hours a week on screens.
