Answer: 12.5 cm
Step-by-step explanation:
Equation would be:
1:80
?:1000
So you'll just have the cross multiply the equation above to find ? ( scale drawing lake). It'll be 1000*1/80 which will be 12.5 cm.
Answer: taking the bus to work takes 13 minutes longer.
Step-by-step explanation:
It usually took josh 2/5 of an hour to ride his bike to work. This means that the number of hours that it took Josh to ride his bike to work is
2/5 × 60 = 24 minutes
But on Monday, his bike was broken, so he took the bus to work which took 5/8 of an hour. This means that the amount of time that it took Josh spent on the bus to work is
5/8 × 60 = 37.5 minutes
The difference between the time spent riding the bike and time spent on the bus is
37.5 - 24 = 13 minutes
Let me try . . .
When two lines intersect, they form four (4) angles, all at the same point.
There are two pairs of angles that DON't share a side, and a bunch of other
ones that do share sides. A pair of angles that DON't share a side are called
a pair of "vertical angles".
A pair of vertical angles are equal, but this problem isn't even asking you about
that; it's just asking you to find a pair of vertical angles.
Since you and I are not sitting together at the same table, I can't point to
the drawing and point out different angles to you. You just have to go
through the choices, and find a choice where both angles are formed from
the same two lines.
The first choice (KRE and ERT) is no good, because KR, RE, and RT
are parts of three different lines.
Check out the other 3 choices, and you're sure to find the only one where
both angles are formed by the same two lines.

Answers in step-by-step.
Step-by-step explanation:
We are going to make Sarah the variable "s."
Using the given information, the following equation is derived to calculate Sarah's distance.
And the following equation will be used to calculate what Sarah collected using "p" for pledged money.
If Sarah collected $450 in pledges, we can use the preceding formula to calculate her distance.
- P=18S
- 450=18S
- 450/18=S
- 25 miles = S
Using Sarah's distance, we can calculate Semir's either the first equation.
- S=2n-5
- 25=2n-5
- 30=2n
- 15=n
- Semir walked 15 miles.
We already found Sarah's distance to be 25 miles.
Now SungSo is making the same amount as Sarah. He collects $450 total, but he got $72 from his grandmother initially, so subtract 72 from 450 to get the amount he collected from walking.
His formula is the same as Sarah's, but we'll use SS for his variable.
- P=18SS
- 378 = 18SS
- 378/18=SS
- 21= SS
- SungSo walked 21 miles.
The area of the square is 14*14 = 168 ft^2.
The area of the circle is πr^2. The radius is diameter/2 = 7. The area of the circle is 3.14*(7)^2 = 3.14*49 = 153.86 ft^2.
The area of the shaded part is the area of the square minus the area of the circle = 168 - 153.86 = 14.14 ft^2.
