From the problem we know that Hanna saves one-half of her paycheck each week, so she saves
. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is
.
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>
representing the number of weeks, we can model the situation as follows:
Answer:
Step-by-step explanation:
Use Pythagoras theorem
a = √ 8² + 5² = 9.4
b = √ 17² - 12² = 12.0
Answer:
7a²/16
Step-by-step explanation:
Area of the triangle PTS
½ × a × a
a²/2
Length of PS:
sqrt(a² + a²)
asqrt(2)
Length of MS:
¼asqrt(2)
Triangles MCS and TPS are similar
With sides in the ratio:
¼asqrt(2) : a
sqrt(2)/4 : 1
Area of triangle SMC:
A/(a²/2) = [(sqrt(2)/4)]²
2A/a² = 1/8
A = a²/16
Area of PTMC
= a²/2 - a²/16
= 7a²/16
Answer:-52
Step-by-step explanation:
-4x-40-6=-3x+6
-4x-46=-3x+6
-52=x
