Answer:

The cost of 16 oz of granola should be $16.16

Step-by-step explanation:

Given that,

The cost of 3 oz of granola is $3.03

We need to find the cost of 16 oz of granola..

As 3 oz = $3.03

1 oz = (3.03/3) = $1.01

The cost of 16 oz will be :

16 oz = 16×1.01

= $16.16

Hence, the cost of 16 oz of granola should be $16.16.

It took 48 minutes to drive downtown An app estimated it would be less than that If the error was 20% what was the apps estimate

Zina [86]

Answer:

The app's estimate was 38.4 minutes.

Step-by-step explanation:

Suppose, the app's estimated time was $t$ minutes.

Given that, it took 48 minutes to drive downtown. So, the error in estimated time by the app $=(48-t)$ minutes.

It is also given that the error was 20%. So, the amount of error $= (48*0.20)=9.6$ minutes.

Thus, the equation will be......

$48-t= 9.6\\ \\ -t=9.6-48\\ \\ -t=-38.4\\ \\ t= 38.4$

So, the app's estimate was 38.4 minutes.

Find the values of x and y. y 45

Mila [183]

Answer:

x = $\sqrt{2}$

y = 2

Step-by-step explanation:

By applying tangent rule in the given triangle,

tan(45°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

1 = $\frac{\sqrt{2}}{x}$

x = √2

By applying sine rule in the given triangle,

sin(45°) = $\frac{\text{Opposite side}}{\text{Hyotenuse}}$

$\frac{1}{\sqrt{2}}=\frac{\sqrt{2}}{y}$

y = $(\sqrt{2})^2$

y = 2
