Step-by-step explanation:
sorry I can only explain as there are no labels to each diagram
The first diagram is single and can solved using triangular formular given as 1/2 ×base × height
A = 1/2 × 5 × 12
A = 30cm^2..
as for the second one...it consist of 2 diagrams which will be solved separately before adding ...it can simply be done using Pythagoras theorem..
To get the smaller part ...out tita is 45degrees while our adjacent is 4 and opposite is x we are to find x which is the height...
using SOH CAH TOA...
WE HAVE TAN45= opp/adj
Tan45= x/ 4
Tan 45 =1 ...so
1 = x/ 4
and x= 4 ...
so...having our height as 4 and base as 4 ..
Area of smaller triangle become 1/2 × 4 × 4
A = 8cm^2 ...
......SOLVING FOR THE SECOND DIAGRAM ..
WE HAVE the height as ( dotted spot + undotted spot ) = 4 + 4 = 8cm
and our base can be gotten from
Tan45 = opp / adj
1 = 8/x ..
x = 8cm ....so the base is 8 and the height is 8
..
The Area becomes 1/2 × 8×8 = 32cm ...
Total area becomes 32cm + 8cm = 40cm^2
your answer should be C) y= -3/5x
because y=mx+b
the m=slope
b= y-intercept
Answer: 2/15
Explanation :
1 - (1/5 + 2/3)
1 - (3/15 + 10/15)
1 - 13/15
15/15 - 13/15
= 2/15
$160.00 earned per week divided by the $8.00 paid per hour equals how many hours worked ...
$160.00 / $8.00 = x
160 / 8 = x
20 = x
Answer:
Step-by-step explanation:
Answer is 5 candies.
$25 is her total amount so you need to subtract the $8 that she paid for her ticket with.
The answer to that subtraction is $17.
With $17, you divide by $3.25 (price of candy) to get the number 5.2. Except, you can't buy a small bit of a candy, so you would be able to buy 5 in total.
