Plug in 8 for g(8) to get 8(2) + 1 which is equal to 17, plug in 7 for f(x) to get 10-7 which is equal to 3. 17 + 3 is equal to 20 which means g(8) + f(7)= 20

The trinket store is open for 14 hours per day. They sell an average of 5 trinkets per hour. The back storeroom currently has 56
tekilochka [14]
Q1)
write the equation that estimates the number of trinkets T that will be in the storeroom after H hours
Initially the number of trinkets available = 560
every hour they sell an average of 5 trinkets 
therefore in H hours, number of trinkets that will be sold = 5 trinkets/hr * H hrs
number of trinkets sold in H hours = 5H
the remaining number of trinkets = T
T = number of trinkets initially available - number of trinkets sold 

T = 560 -5H

Q2) 
How many days will it take to run out of trinkets 
number of trinkets sold per hour - 5 
number of hours the shop is open for - 14 hours / day
during one day number of trinkets sold - 5 trinkets/hr x 14 hrs/ day
                                                              = 70 trinkets per day
there are 560 trinkets available 
and if 70 trinkets are sold per day 
number of days it takes to sell 560 trinkets 
days = 560 trinkets / 70 trinkets/day 
         = 8 days 

the third response is correct - 1) T = 560 -5H
                                                2) 8 days

Sebuah balok berukuran panjang 3 cm, lebar 4 cm, dan panjang diagonal ruang 13 cm. Volume balok adalah
kramer

Answer:

V=144\ cm^3

Step-by-step explanation:

#We use the base diagonal and the height diagonal to calculate the beam's height:

h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm

#The volume of the beam can then be calculated as:

V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3

Hence, the beam's volume is 144\ cm^3

What is the solution to the following equation 4(3x-6)+15=27
Svetlanka [38]

Answer:

x = 3

Step-by-step explanation:

4(3x - 6) + 15 = 27 \\ 12x - 24 + 15 = 27 \\ 12x - 24 = 27 - 15 \\ 12x - 24 =1 2 \\ 12x = 12 + 24 \\ 12x = 36 \\  \frac{12x}{12}  =  \frac{36}{12}  \\ x = 3
