Hi, the answer is ;
Answer:
12 dimes and 27 nickels
Step-by-step explanation:
.05N + .1d = 2.55
N= 3d - 9
0.05 (3d-9) + 0.1d = 2.55
0.15d - 0.45 + 0.1d = 2.55
0.25d = 2.55 + 0.45
0.25d = 3
D = 12
N = 3 (12) - 9
N = 36 - 9
N = 27
Horse- 50l
sheep-4l
chicken-200ml
first you have to convert all the symbols into one, so we'll convert liters into milliliters,
1000ml=1l
horse= 50 ×1000=50000ml
sheep=4×1000=4000ml
chicken= 200ml
so now we have to multiply them by the number of animals,
h=50000ml×3=150000ml
s=4000×15=60000ml
c=200×12=2400ml
now add them together,
150000+60000+2400=212400ml
convert it into litres,
212400÷1000=212.4l
answer= 212.4 l
Answer:
$186.2
Step-by-step explanation:
38 kg costs $144.40
∴ 1 kg costs = 
= $3.8
49 kg costs = 3.8 x 49
= $186.2
Answer:
1. 30°
2.90°
3. 12 units
Step-by-step explanation:
I can't believe there's nothing confirming that this is a parallelogram/a rhombus?! Assuming is awful, and I wish you could say you can't know for sure lol but for the sake of this answer, let's just call it a rhombus. (There was probably some context elsewhere that you didn't put over here, hopefully.)
1.
The reason I say this is: in a rhombus, the diagonals bisect the angles. This means that the diagonals split the angles they meet into two equal parts. That way, it would make sense. m∠QPR=m∠SPR=30°.
2.
If it is a rhombus, the diagonals are perpendicular to each other, so m∠QTP should be 90°.
3.
Diagnonals in a rhombus (and in any parallelogram) bisect each other, so PT=TR=6, and RP=PT+TR=12 units.
Sorry if this is all dreadfully wrong, and I hope I helped you!
