Answer:
a) a to the power of 2
b) c
Step-by-step explanation:
E Value of the Expression a. 50 times the sum of 64 and 36. 50 x(64+36)
Let us say that:
x = mass of 10% titanium alloy required
y = mass of 20% titanium alloy required
To solve this problem, we set-up two mass balances or
equations.
Overall mass balance: x
+ y = 100
x
= 100 – y ---> 1
Titanium mass balance: 0.10 x + 0.20 y = 0.17 (100)
0.10
x + 0.20 y = 17 ---> 2
Now we combine equations 1 and 2:
0.10 (100 – y) + 0.20 y = 17
10 – 0.10 y + 0.20 y = 17
0.10 y = 7
y = 70 g
Calculating for x using equation 1:
x = 100 – y
x = 100 – 70
x = 30 g
Answer:
x = 30 g of 10% titanium alloy required
y = 70 g <span>of 20% titanium alloy required</span>
Answer:
771₈ added to 511₈ equals 1,282.
A-y=4.50x ,4.50 is the slope because for each shirt she sells that is how much she makes and she doesn't have an original value for a y-intercept.
B- 1 ,each tee-shirt she makes she will profit 4.50 for a single so she makes money after the first one.
C-129 ,because you need to find how much each tee-shirt costs in the bunch of 70 and divide it from 800 and round to 129.
