A company makes two calculator models, one designed specifically for financial use and the other designed for scientific use. Th

mihalych1998 [28]

Answer:

280 financial
20 scientific

Step-by-step explanation:

The linear programming problem can be formulated as ...

minimize 10f +12s subject to ...

10f +20s ≥ 3200 . . . . number of chips used

f + s ≥ 300 . . . . . . . . . .number of switches used

f ≥ 100 . . . . . . . . . . . . .minimum number of financial calculators

Graphing these inequalities, we find the feasible region to be bounded by the points (f, s) = (100, 200), (280, 20), (320, 0). The one of these that minimizes the number of production steps is ...

f = 280, s = 20

280 financial and 20 scientific calculators should be produced to minimize the number of production steps.

1. A drawing of a triangular park shows that the sides measure 12 m, 30 m, and 18 m. Can these dimensions be correct?

Varvara68 [4.7K]

Answer: 1. It is not possible to construct a triangle of given measure sides.

2. The value of ∠A is 44°

Step-by-step explanation:

Given: Three sides of a triangle

Let a= 12 m , b=30 m and c= 18 m

Now as we know

The sum of two sides of a triangle is always greater than the third side

Therefore we need to show

a+b>c -----(i)

b+c>a -----(ii)

c+a>b -----(iii)

(i a+b= 12+30 = 42>18= b ⇒ a+b>c

ii) b+c=30+18= 48 >12=a ⇒ b+c>a

iii) c+a=18+12=30=b ⇒ c+a= b

Therefore the third condition does not verified

Hence, it is not possible to construct a triangle of given measure sides.

As we now triangle sum property which states that the sum of all the three angles of a triangle is 180°

So we have

$x+59+84+x+51=180\\\\\Rightarrow 194 +2x=180\\\\\Rightarrow 2x= 180-194\\\\\Rightarrow 2x=-14\\\\\Rightarrow x= -7$

Therefore

$\angle A = x+51= -7+51= 44^\circ$

Hence, the value of ∠A is 44°

Donte used mental math to find the exact sum of 386 and 14. Which strategy could Donte have used?

Nostrana [21]

Answer:

380 + 6 + 14

Step-by-step explanation:

The sum of 386 and 14 is 386 + 14 = 400.

To find which stategy he used, we find the results of each sum, and it has to be 400.

380 + 6 + 14

380 + 6 + 14 = 386 + 14 = 400

So this is the strategy that he could have used.

380 + 14 + 14

380 + 14 + 14 = 394 + 14 = 408

Result different of 400, which means that this was not the strategy

386 + 10 + 4 + 14

386 + 10 + 4 + 14 = 386 + 14 + 14 = 408

Result different of 400, which means that this was not the strategy

386 + 14 + 80 + 6

386 + 14 + 80 + 6 = 400 + 86 = 486

Result different of 400, which means that this was not the strategy
