The true value is 25.7 ml.
The calculated error is 15.6%.
Thus, the error amount equals 0.156 times 25.7, which calculates to 4.0092 ml.

The percentage error indicates that the student's measurement could either exceed or fall short of the true value by this error amount.

This leads to two potential readings:
one possibility is: 25.7 + 4.0092 = 29.7092 ml
the other possibility is: 25.7 - 4.0092 = 21.6908 ml

To calculate 15.6% of 25.7, multiply 25.7 by 15.6% in its decimal equivalent, which is 0.156.
Thus, 25.7 multiplied by 0.156 equals 3.9936.
The outcomes for the student's measurements are 25.7 plus or minus 3.9936, resulting in two possible figures of 29.4936 and 21.7064.

A recipe for salsa uses 65% tomatoes. If a batch contains 5.2 cups of tomatoes, how large is the batch of salsa.
AnnZ [12381]

The salsa consists of 65% tomatoes, which amounts to 5.2 cups.

Let’s denote the total salsa as "x" cups, representing 100%. Given that 5.2 cups makes up 65%, we have:

\bf \begin{array}{ccll} cups&\%\\ \cline{1-2} 5.2&65\\ x&100 \end{array}\implies \cfrac{5.2}{x}=\cfrac{65}{100}\implies \cfrac{5.2}{x}=\cfrac{13}{20}\implies 104=13x \\\\\\ \cfrac{104}{13}=x\implies 8=x

20 POINTS Compost costs $10 per cubic yard and topsoil costs $2 per cubic yard. Maria needs more than 10 cubic feet of topsoil.
Inessa [12570]
I can't view the graph, but let’s apply reasoning
hmm, since it requires more than 10 cubic feet of topsoil, the first and second options aren’t feasible

let’s analyze the costs
third option
10*1=10
2*12=24
10+24=34 and 34<50, that works

fourth option
3*10=30
2*12=24
30+24=54
54>50, that's too high


the answer is the third one
the one with 1 cubic yard of compost and 12 cubic yards of topsoil

f Khan had an army of 10,000 soldiers at the lowest level, how many men in total were under him in his organization? (b) If Khan
babunello [11817]

Cette question est incomplète, la question complète est;

Gengis Khan organisait ses hommes en groupes de 10 soldats dirigés par un « leader de 10 ». Dix « leaders de 10 » étaient sous un « leader de 100 ». Dix « leaders de 100 » étaient sous un « leader de 1 000 ».

(a) Si Khan avait une armée de 10 000 soldats au niveau le plus bas, combien d'hommes en tout étaient sous son commandement dans son organisation?

(b) Si Khan avait une armée de 5 763 soldats au niveau le plus bas, combien d'hommes en tout étaient sous son commandement dans son organisation?

On suppose que les groupes de 10 doivent contenir 10 si possible, mais qu'un groupe à chaque niveau peut avoir besoin de témoigner moins

Réponse:

a) = 11110 soldats

b = 6404 soldats

Explication étape par étape:

Étant donné que Khan a disposé ses hommes en groupes de 10 sous un « leader de 10 », dix « leaders de 10 » étaient supervisés par un « leader de 100 », et dix « leaders de 100 » étaient dirigés par un « leader de 1000 »

alors

a) Si Khan avait une armée de 10 000 soldats au niveau le plus bas, combien d'hommes au total étaient sous son organisation?

MAINTENANT

Nombre de soldats = 10 000

Rang le plus bas (soldat) = 10000

troisième plus haut (leader de 10) = 10000/10 = 1000

deuxième le plus élevé (leader de 100) = 1000/10 = 100

Le plus haut (Leader de 1000) = 100/10 = 10

donc le total = 10000 + 1000 + 100 + 10 = 11110 soldats

b) Si Khan avait une armée de 5 763 soldats au rang le plus bas, combien d'hommes au total étaient sous son commandement dans son organisation? On suppose que les groupes de 10 doivent contenir 10 si possible, mais qu'un groupe à chaque niveau peut avoir besoin de témoigner moins

MAINTENANT

Nombre de soldats = 5 763

Rang le plus bas (soldat) = 5763

troisième plus haut (leader de 10) = 5763/10 = 576.3 = 577 (nombre entier requis pour un humain)

deuxième le plus élevé (leader de 100) = 577/10 = 57.7 = 58

Le plus haut (Leader de 1000) = 58/10 = 5.8 = 6

donc le total = 5763 + 577 + 58 + 6 = 6404 soldats
