Answer:

84 grams and 5 ounces

Step-by-step explanation:

because one ounce equals 28 grams, that means 3 ounces = 3 * 28 = 84

because 28 grams equals 1 ounce, 140 grams = 140 / 28 = 5 ounces

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
saw5 [17]

Using exponential function concepts, it is found that it represents a decay of 0.9%.

<h3>What is an exponential function?</h3>

A decaying exponential function is <em>modeled </em>by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function is:

A(t) = 9300(0.991)^{6t}

Hence:

1 - r = 0.991

r = 0.009

Thus, it represents a decay of 0.9%.

Mike's truck engine holds 1 and 1/4 gallons of oil if there are 3 quarts of oil in the engine now how many more quarts of oil do
HACTEHA [7]

Answer:

2 more quarts of oil is needed to fill

the engine to capacity

Step-by-step explanation:

Here, we want to calculate how many more quarts of oil is required to fill the engine to capacity

We have to convert the capacity to quarts

Mathematically, 1 gallon = 4 quarts

So 1 1/4 gallon will be 5/4 * 4 = 5 quarts

So the number of quarts needed to fill the engine to capacity will be 5 quarts - 3 quarts = 2 quarts

The Pyraminx is a Rubik's cube-type toy in the shape of a tetrahedron. The Pyraminx shown below has edges 15\,\text{cm}15cm long
____ [38]

Answer:

8.727

Step-by-step explanation:

Since the below edge, d = 15 cm, and the height, h = 12.2 cm, we will use the Pythagorean  theorem to find the distance r.

d^2=r^2+h^2

(15)^2 = r^2+(12.2)^2

r^2 = (15)^2-(12.2)^2=225-148.84=76.16

r=\sqrt{76.16}=8.727
