Answer:
<u>2047.5 cubic inches</u>
Step-by-step explanation:
Volume of the storage chest :
<u><em>Length × Width × Height</em></u>
<u><em /></u>
============================================================
Given :
⇒ Length = 26 in.
⇒ Width = 7.5 in.
⇒ Height = 10.5 in.
===========================================================
Solving :
⇒ Volume = 26 × 7.5 × 10.5
⇒ Volume = 273 × 7.5
⇒ Volume = <u>2047.5 cubic inches</u>
Answer:
first of all the formula
y = mx+c
where m is slope and c is y-intercept.
now substitute the values-
y = 2x - 5
(for the slope here is 2 and the part where the line intercepts y axis is -5
therefore
y = 2x-5

Answer:
We have 40% antifreeze and 70% antifreeze and we need to make 240 liters of 64% antifreeze.
We set up 2 equations where "f" is the 40 % and "s" is the 70%
A) f + s = 240
B) .40f + .70s = (.64 * 240) (or 153.6)
To solve both equations we multiply A) by -.40
A) -.40 f - .40 s = -96.00 then we add this to B)
B) .40f + .70s = 153.60
.30s = 57.6
s = 192
f = 48
48 liters of 40% = 19.20 liters of antifreeze
192 liters of 70% = 134.40 liters of antifreeze
That equals 153.60 liters of antifreeze in a TOTAL liquid amount of 240 liters.
Double Check
153.60 / 240 = 64% antifreeze.
