Answer:
A= 41° a=9.84... b=11.32...
Step-by-step explanation:
given B = 49° and C = 90°
and A + B + C = 180
so 49+90+A=180
A= 41°
we also know c (small) is 15 units
and maybe you know this SOH CAH TOA? no, i'm not calling anyone names :P this is just the mnemonic to memorize how sin , cos and tan fit sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj
Hyp is the hypontenuse of the triangle ( the long side). Opposite (Opp) means the side opposite from what ever angle you are starting at..adjacent (Adj) means what ever angle is next to where you are starting from.
use Cos(49) to find the side a
a is an adjacent side to the 49 angle. We know the Cos and we know the Hyp .. so solve for adj...
Cos(Ф)=Adj/ Hyp
Hyp*Cos(Ф)=Adj
15*Cos(49)= Adj
9.84...=Adj=a
now lets' use sin for the opposite side or b
sin(Ф)=Opp/Hyp
Hyp*Sin(Ф) = Opp
15*sin(49)= Opp
11.32...= Opp =b

Preston started the summer owing $15 to his brother and $20 to his sister. He earned $75 mowing lawns, and paid his brother and sister back what he owed them. Which expression represents the amount of money that Preston has after paying back his brother and sister?
Answers
Answer:
$75 - $15 - $20 = $40
Step-by-step explanation:
Given that:
Money owed by Preston to his brother = $15
Money owed by Preston to his sister = $20
Total money earned by Preston = $75
Now, the money is paid back that he owed to his sister and brother.
To find:
The expression to represent the amount of money left with Preston after clearing all his dues?
Solution:
Once Preston pays back the money that he owed to his brother and sister, he will not have all $75 left with him.
He will have lesser amount of money.
Money left with Preston = Total money earned by Preston - Money owed to brother - Money owed to sister
Putting the values given as per the question statement, we get:
Money left with Preston = $75 - $15 - $20 = $40
Therefore, the expression to represent the amount of money left with Preston = $75 - $15 - $20 = $40

1. A music club membership costs $17.00 and $7.00 per CD.
2. The total cost of a carpet is $3.00 times the number of square feet.
3. The amount of money you earn for allowance is $20 times the number of months.
4. The cost of belonging to a fitness club is $200 to join and $30 a month in membership dues.
Answers
Answer:
1. $17 + $7C.
This equation provides the total cost if you want to purchase a music CD along with a music club membership. C represents the amount of CDs you wish to purchase, and since each CD costs $7, the amount of money you would need to purchase C amount of CDs is $7C.
2. $3A.
This equation provides the total cost of the area of carpet you want to purchase. A represents the area of the carpet that you want to purchase, measured in square feet as provided by the question, and since each square foot costs $3, the total cost is $3A.
3. $20M.
This equation provides the total money you earn for allowance after M months. M is the number of months that have passed, and since you earn $20 for allowance every month, the total allowance you have earned is $20M.
4. $200 + $30M.
This equation provides the total cost for joining and staying in a fitness club for M months. The initial cost, $200, is applied no matter how many months you join, so we add it from the start; since each month, M, you have to pay $30, the total amount of membership dues is $30M.

In a cricket match, Rajat scored thrice as many runs as Devansh.
Together they fell short of 8 runs of a triple century. Find their scores.
Answers
Answer:
let jivesh score x runs so rajat scores 3x runs
total runs = 300-8 = 292 runs
so x+3x = 292
4x = 292
x = 292/4
x = 73
so jivesh score 72 runs and rajat scores 216 runs
Step-by-step explanation:
Answer:
73 for Devanesh. 219 for Rajat
Step-by-step explanation:
If a triple century is 300 then 300-8 = 292 runs that they made. They made a total of 3t+t=292. Means 4t=292. Means t=73. So 73 is the runs for Devanesh.219 for Rajat.
Find the width w of a box with volume V = 120 cm3, l = 3 cm and h = 5 cm.
Answers
Answer:
8
Step-by-step explanation:
the volume of a box is L x W x H
so if you take the length x height, you can divide the volume by that to get your width.
hope this helps!! :)
The width of the rectangular box will be; 8cm
What is the volume of a rectangular box?Given that the formula for calculating the volume of a rectangular box is expressed as:
V= w l h
Where L is the length
w is the width
h is the height
Given the following parameters;
Length l = 3 cm
Volume V = 120cm³
Height = 5cm
Find the width of the box as :
V= w l h
120 = w x 3 x 5
w = 120/ 15
w = 8
Hence, the width of the rectangular box will be 8 cm.

what is 100000x5+900-705=?
Answers
Answer:
500195
Step-by-step explanation:
The required value of the given expression 100,000 × 5 + 900 - 705 is 500,195.
The expression is given as follows:
100,000 × 5 + 900 - 705
To evaluate the expression 100,000 × 5 + 900 - 705, we follow the order of operations (also known as PEMDAS). Here's how we can solve it step by step:
Perform the multiplication: 100,000 × 5 = 500,000.
Add the result from the multiplication to 900: 500,000 + 900 = 500,900.
Subtract 705 from the previous result: 500,900 - 705 = 500,195.
Therefore, the value of the expression 100,000 × 5 + 900 - 705 is 500,195.
