circumference of circle: 2πr ("r" is the radius)
==========
2πr 2π(2.5)5π15.7 cmAnswer:
15.7 cm²
Step-by-step explanation:
Given:
[tex]\text{Radius of circle: 2.5 cm}[/tex]
Formula:
[tex]\text{Circumference:} \ 2\pi r[/tex]
Substitute the radius in the circumference formula:
[tex]\implies \text{Circumference:} \ 2\pi r[/tex]
[tex]\implies \text{Circumference:} \ 2\pi (2.5)[/tex]
Take π as 3.14 (Approx. value of π):
[tex]\implies \text{Circumference:} \ 2(3.14)(2.5)[/tex]
Simplify the circumference:
[tex]\implies \text{Circumference:} \ (3.14)(5)[/tex]
[tex]\implies \text{Circumference:} \ 15.7 \ \text{cm}^{2}[/tex]

The first bricklayer can build a wall in 15 days, the second bricklayer can build the same wall in 10 days. How long will it take them to build the wall together?
Please help fast ASAP!!
Will mark brainiest!!!
Answer:
6 days
Step-by-step explanation:
If the first bricklayer can build a wall in 15 days, he can build 1/15 of a wall in one day.
If the second bricklayer can build a wall in 10 days, he can build 1/10 of a wall in one day.
Therefore, if they work together, in one day they will complete
1/15 + 1/10 = 1/6
of the wall.
Since they can complete 1/6 of the wall in one day, they can complete 6/6 or one wall in 6 days.

Answer:
B -- Recipe 2 (Gluten-Free)
Step-by-step explanation:
Recipe 1
5 / 16 = 0.3125
Recipe 2
3 / 8 = 0.375
Recipe 2 (Gluten-Free) has a higher ratio so it must have a stronger taste.
Answer:
Your answer would be:
B.) The gluten-free batch has the stronger butterscotch
Regular batch:
5 / 21
5 / 21 = 25 / 110
Gluten-free batch:
3 / 11
3 / 11 = 30 / 110
Solution:
30 / 110 > 25 / 110
In conclusion, the gluten-free batch has the stronger butterscotch.

How much more does the student need to save to buy the laptop
Answer:
A
Step-by-step explanation:
Starting amount = 307.50
1 month saving = 100
5 month saving = 5*100 500.00
Total so far 807.50
Let the total amount be x
75% *x = 807.50
75/100 x = 807,59 Multiply both sides by 100
75 x = 807.50 * 100
75 x = 80750 Divide by 75.
x = 80750 / 75
x = 1076.67
That is not the answer. That's the total cost of the laptop.
The amount needed is
Amount needed = Total Cost - what has been saved
Amount needed = ????
Total Cost = 1076.67
What has been saved = 807.50
Answer
Amount needed = 1076.67 - 807.50 = 269.17

Dana just finished paying off the $15,400 loan she took out four years ago. the loan had 6.68% interest, compounded monthly. if dana paid a total of $18,321.60, how much did she pay in service charges? a. $730.08 b. $366.49 c. $1,028.72 d. $266.76 please select the best answer from the choices provided a b c d
If Dana paid a total of $18,321.60, then the amount that she paid for in service charges will be $730.08
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
For service charge
[tex]\rm Pv = PMT[(1 - (1 + (r/k))^{-kn}) / (r/k)][/tex]
Where;
Pv is the amount of the loan = $15400
PMT is monthly payment
R is interest rate = 6.68% = 0.0668
K is number of times compounded monthly = 12
N is time = 4years
PMT the subject of the formula gives
[tex]PMT = Pv/ [(1 - (1 + (r/k))^{-kn}) /(r/k)][/tex]
PMT = 15,400 ÷ ((1 − (1 + 0.0668 ÷ 12)^(−12 × 4)) ÷ (0.0668 ÷ 12))
PMT = 366.49
Thus, the total amount paid
A = 366.49 × 12months × 4years
A = $17,591.52
Thus, the Service charge is
S.C = 18,321.60 − 17,591.52
S.C = $730.08

Answer:
9.
Step-by-step explanation:
6 9 12 15:- multiplying by 3.
Answer:
B) 9
Step-by-step explanation:
When looking in both the horizontal and vertical direction of the missing space, we can see that the difference between the two numbers, 12 and 15, is 3.
15 - 12 = 3
Using this, we can see that each space on the second row and second column change by 3. Therefore, when looking at the missing space in the sequence, we can figure out that it is 9 by adding 3 to 6.

What is mZRST in degrees? O 78° O 84° O 120° O 156°
Answer:
rst = ust + usr
6x+12 = 78 + 3x - 12
3x = 54
3x+66 = 54 + 66
3x +66= 120
thus rst = 120
The measure of angle ∠RST in degree is 156°
What is measure of an angle?The measure of angle is the amount of rotation performed by initial side to get the terminal side. A complete angle is divided by 360 equal parts we get 360 number of small angles. Each of these small angle has measure 1 degree.
Given that, ∠RSU=78° , ∠UST=(3x - 11)° and ∠RST=(6x + 12)°
Now, ∠RSU+UST=∠RST
Putting the values of ∠RST and ∠UST we get,
78 + (3x - 12) = 6x + 12
78 + 3x - 12 - 6x - 12 = 0
54 - 3x = 0
3x = 54
So, x = 54/3=18
Therefore, (6x + 12)°=(6×18 + 12)°
=(144 + 12)°
=156°
Hence the measure of angle ∠RST is 156°
