Answer:

3^-3 we can write if the power is in negative sign in fraction it will be positive like if a^-2=1/a2

so if the power of 3 is -3 like 3^-3 then we can write it as 1/3^3 or we can write 1/3*3*3

3^-3=1/27

Write the next whole number after 6748nine in the base-nine system.

ale4655 [162]

Answer:

Step-by-step explanation:

$6748_9 = 6 *(9^3) + 7 * 9^2 + 4 * 9^1 + 8 * 9 ^ 0 = 4994_{10}$

Hence, on base 10, the next whole number is 4995 and if we convert back to base 9, we will have

$6* 9^3 + 7*9^2 + 5*9*1 = 4374 + 576+45 = 4995_{10}$

Therefore, the number on base 9 will be 6750

Find the value of y if the value of x is 2 for each equation and match it with the appropriate result.

Xelga [282]

Answer:

3, 0, 2, -2

Step-by-step explanation:

Put x=2 into each equation and solve for y.

y = 5 -2

y = 3

3·2 +2y = 6

2y = 6 -6 = 0

y = 0

2·2 +y = 6

y = 6 -4

y = 2

5·2 +3y = 4

3y = 4 -10 = -6

y = -2

A government buys `x`fighter planes at `z` dollars each, and `y` tons of wheat at w dollars each. It spends a total of `B`dollar

Veronika [31]

The equation whose solution is the given quantity is 90,000,000 = 2,000,000w + 15,000w where w = $44.67

<h3>Equation</h3>

B = xz + yw

Where,

B = Total cost = 90
x = number of fighter plane = 20
y = tons of wheat = 15,000
w = cost of each tons of wheat
z = cost of fighter plane
z = 100,000w

B = xz + yw

90,000,000 = (20 × 100,000w) + (15,000 × w)

90,000,000 = 2,000,000w + 15,000w

90,000,000 = 2,015,000w

w = 90,000,000 / 2,015,000

= 44.6650124069478

Approximately,

w = $44.67
