Answer:
D AND E
Step-by-step explanation:
Try this:
1) note that weight of pure antifreeze before mixing and after mixing is the same. So, if 'x' is weight of pure antifreeze in 50% solution, it is possible to make up equation before mixing: 0.5x+0.2*90.
2) there are 0.2*90=18 gal. of pure antifreeze in the 20% solution. If 'x' gal. is the weight of pure antifreeze in 50% sol. and 18 gal. is the weight of pure antifreeze in 20% sol., it is possible to make up an equation after mixing: 0.4(x+18).
3) using the both parts: 0.5x+0.2*90=0.4(x+18) ⇒ x=54 gal. of <u>pure</u> weight.
4) to find 50% solution of 54 gal. pure weight just 54:0.5=108 gal.
Answer: 108 gal.
Answer:
D. AG ≅ NP
Step-by-step explanation:
Given that quadrilateral ACEG is congruent to quadrilateral NMRP, this means that all the corresponding sides of both quadrilaterals are congruent to each other.
Considering the arrangement of the letters we can reduce the following:
AC corresponds to NM, therefore AC ≅ NM.
CE corresponds to MR, therefore, CE ≅ MR.
AG corresponds to NP, therefore AG ≅ NP.
EG corresponds to RP, therefore, EG ≅ RP.
The only statement that is true among the options given is:
AG ≅ NP
pretty sure its y=2^x aka B
