How u write an inequality for brigitte is shorter than 5 feet (brigitte height =h)
padilas [110]
You have said that Brigitte is shorter than 5 feet. Translating your statement into rigorous mathematical terminology, we would write "Brigitte's height is less than 5 feet.". Then, using 'h' to represent Brigitte's height, and '<' to represent the words "less than", we can write the statement symbolically as [ h < 5 feet ].

sattari [20]

Answer:

After four years the house was worth $128,891.03

Step-by-step explanation:

170828(x)^12 = 73828

solve for x

x = 0.932 (House depreciates by 6.8% yearly)

plug in x and change into function and substitute 4 for 12 because it's 4 years

170828(0.932)^4

I WILL GIVE BRAINLIEST IF CORRECT !!!!
rosijanka [135]

Answer:

C. 3.2\times 10^{1}

Step-by-step explanation:

d_r = Diameter of a red blood cell = 0.0008\ \text{cm}

d_w = Diameter of a whooping cough virus = 2.5\times 10^{-5}\ \text{cm}

Ratio of the diameter of the red blood cell to the diameter of the whooping cough virus

\dfrac{d_r}{d_w}=\dfrac{0.0008}{2.5\times 10^{-5}}=\dfrac{0.0008}{25\times 10^{-6}}=\dfrac{0.0008\times 10^6}{25}\\\Rightarrow \dfrac{d_r}{d_w}=\dfrac{800}{25}\\\Rightarrow \dfrac{d_r}{d_w}=32=3.2\times 10^{1}

The required ratio is 3.2\times 10^{1}.
