An ant weighs 2 x 10^-3 grams, and a lion weighs 1 x 10^5. The lion's weight is 5 x 10^x times greater than the ant's weight. Wh

julsineya [31]

Answer:

x=7

Step-by-step explanation:

Information provided

Weight of ant= $2*10^{-3} grams$

Weight of lion= $1*10^{5}$ but units are not provided, assuming this unit is also grams

How many times lion's weight exceed an ant

$\frac {1*10^{5}}{2*10^{-3}}=50000000$

= $5*10^{7}$

Therefore, the value of x=7 if the unit for weight of lion is assumed to be same as unit for weight of an ant

What is the value of z in the equation 2(4z − 6 − 6) = 170 − 46? 12.5 15.5 16.5 18.5

vivado [14]

2(4z - 6 - 6) = 170 - 46

2(4z - 12) = 124 |use distributive property: a(b - c) = ab - ac

8z - 24 = 124 |add 24 to both sides

8z = 148 |divide both sides by 8

z = 18.5

Aki's Bicycle Designs has determined that when x hundred bicycles are built, the average cost per bicycle is given by C(x)equa

Alenkinab [10]

Answer:

20 Bicycles

Step-by-step explanation:

The function for the average cost,C(x) [in hundred of dollars] per bicycle whenever x hundred bicycles are built is given as:

$C(x)=0.5x^2-0.2x+6.756$

The minimum value of C occurs at the axis of symmetry.

Axis of Symmetry, $x=-\frac{b}{2a}$

Comparing with the standard form of a quadratic equation $ax^2+bx+c=0$

a=0.5, b=-0.2

$x=-\frac{(-0.2)}{2*0.5}\\x=0.2$

x=0.2 Hundreds =0.2 X 100 =20

When Aki's Bicycle Designs produces 20 Bicycles, the cost is minimized.
