Determine an equation that describes the number of bacteria in both the foods when they are mixed.
Leto [7]

The equation that describes the number of bacteria in both the foods when they are mixed is; Option C: 35T₂ + 55T + 450

<h3>How to simply quadratic Equations?</h3>

We are given the equations that describes the number of bacteria in both the foods when they are mixed.

Equation for first bacteria is;

N₁(T) = 15T₂ + 60T + 300

Equation for second Bacteria is;

N₂(T) = 20T² - 5T + 150

The equation that describes the number of bacteria in both the foods when they are mixed is;

N₁(T) + N₂(T) = 15T₂ + 60T + 300 +  20T² - 5T + 150

⇒ 35T₂ + 55T + 450

What is Steven’s slugging average if his stats are- Show steps. 25 singles 10 doubles 3 triples 10 homeruns 140 at-bats
kap26 [50]
<h2>Hello!</h2>

The answer is:

The correct answer is c.

SluggingAverage=\frac{25(1)+10(2)+3(3)+10(40)}{140}=\frac{94bases}{140times}=0.671

<h2>Why?</h2>

To calculate the slugging average or slugging percentage, we need to divide the number of total bases by the total times at bat.

SluggingAverage=\frac{TotalBases}{TimesAtBat}

We know that:

A single means 1 base.

A double means 2 bases.

A triple means 3 bases.

A homerun means 4 bases.

So, we know that:

Singles=25=25bases\\Doubles=2*10=20bases\\Triples=3*3=9bases\\Homeruns=10*40=40bases\\TimesAtBat=140

Then, substituting and calculating we have:

SluggingAverage=\frac{25bases+20bases+9bases+40bases}{140}

SluggingAverage=\frac{94bases}{140times}=0.671

Hence, the correct answer is c.

SluggingAverage=\frac{25(1)+10(2)+3(3)+10(40)}{140}=\frac{94bases}{140times}=0.671

Have a nice day!

Use trigonometry ratio to solve the problem, the ratio we use is tan ratio
tan α = \dfrac{\text{opposite}}{\text{adjacent}}

plug in the numbers to find α
tan α = \dfrac{\text{opposite}}{\text{adjacent}}
tan α = \dfrac{500}{400}
tan α = \dfrac{5}{4}
tan α = 1.25
α = tan⁻¹ (1.25)
α = 51.340...
α = 51.3

The answer is second option
