The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
Answer:
105 sweets
Step-by-step explanation:
4×15 = 60
2×15=30
1×15=15
60-15 =45
60+30+15=105
45 minutes * 6 days = 270 minutes at the gum
but we need to change minutes to hours
1 hours = 60 minutes
270 minutes * 1 hr/60 minutes =
270/60 hours
divide top and bottom by 10
27/6
divide top and bottom by 3
9/2
4.5 hours
Answer:
Step-by-step explanation:
Given
Bisector: QS
Required
Determine PQR
Since PQR is bisected to PQS and RQS, we have that
Substitute expressions for PQS and RQS
Collect Like Terms
Divide both sides by 3
Solving for PQR;
Substitute 2 for x
