Determine if each pair of ratios or rates is equivalent. Explain your reasoning. 288 miles on 12 gallons of fuel; 240 miles 10 g

lesantik [10]

Yes they are equivalent. This is because if you simplify each fraction : 288/12 and 240/10 they both equal 24.
$\frac{288}{12} = 24$
$\frac{240}{10} = 24$

Solve for A ? <br><br> Anyone willing to help me :)

GrogVix [38]

Answer:

Step-by-step explanation:

Use the cosine law:

$BC^2=AB^2+AC^2-2(AB)(AC)\cos(\angle A)$

We have:

$BC=a\\\\AB=4\\\\AC=3\\\\m\angle A=32^o\to\cos32^o\approx0.848$

Substitute:

$a^2=4^2+3^2-2(4)(3)(0.848)\\\\a^2=16+9-20.352\\\\a^2=4.648\to a=\sqrt{4.648}\\\\a\approx2.2$

a piece of wood weighing 10 ounces is found to have a weight of 8 ounces after drying. the moisture content was:

tiny-mole [99]

Moisture content should be the difference of the weight of the object wet (10 oz.) and the weight of the object when it was dry(8 oz.)
So,
10 oz. - 8 oz. =moisture content, or 2 oz.
