2 answers:

5 0

Answer
A. Rectangle
D. Parallelogram

Explanation
The four choices are all quadrilaterals with with at least a pair of parallel sides.
A rectangle, a square, and a rhombus have opposite sides been parallel.
For a square and a rhombus, the diagonals are perpendicular.

The diagonals of a rectangle and a parallelograms are not perpendicular.

A gas engine is 6% efficient. What portion of a 12 gallon tank of gas is wasted?

Softa [21]

Answer:19.74 gallons of the gas in the tank is wasted.

Step-by-step explanation:

Since the efficiency of the gas engine is 6%, wastage is #= 100 - 6 = 94%.

Therefore wastage = 94% x 21=94 x21/100=19.74 gallons

An anthropologist finds that a prehistoric bone contains less than 8.1% of the amount of Carbon-14 the bones would have containe

stealth61 [152]

Answer:

20,944 years

Step-by-step explanation:

The formula you use for this type of decay problem is the one that uses the decay constant as opposed to the half life in years. We are given the k value of .00012. If we don't know how much carbon was in the bones when the person was alive, it would be safer to say that when he was alive he had 100% of his carbon. What's left then is 8.1%. Because the 8.1% is left over from 100% after t years, we don't need to worry about converting that percent into a decimal. We can use the 8.1. Here's the formula:

$N(t)=N_{0} e^{-kt}$

where N(t) is the amount left over after the decay occurs, $N_{0}$ is the initial amount, -k is the constant of decay (it's negative cuz decay is a taking away from as opposed to a giving to) and t is the time in years. Filling in accordingly,

$8.1=100e^{-.00012t}$

Begin by dividing the 100 on both sides to get

$.081=e^{-.00012t}$

Now take the natural log of both sides. Since the base of a natual log is e, natural logs and e "undo" each other, much like taking the square root of a squared number.

ln(.081)= -.00012t

Take the natual log of .081 on your calculator to get

-2.513306124 = -.00012t

Now divide both sides by -.00012 to get t = 20,944 years

A recipe calls for One-fourth cup of broth. The largest volume-measuring tool that Tabitha has is a teaspoon. She knows that the

djverab [1.8K]

Answer:

Tabitha will use 12 teaspoons.

Explanation:

According to the question, Tabitha has a largest volume-measuring tool teaspoon, and she wants to use one-fourth cup of broth.

Given that 1 cup consists of 16 tablespoons and 1 tablespoon has 3 teaspoons.

From the data, we can calculate that;

16 tablespoons will be equal to (3*16) = 48 teaspoons.

Therefore, 1 cup = 48 teaspoons.

Substituting the data and we can calculate that 1/4 cup = 48/4 = 12 teaspoons.

1. In Suri's coin purse she has 6 dimes and

ollegr [7]

Answer:

The ratios are not equal

Step-by-step explanation:

Let

x ----> the number of dimes

y ----> the number of quarters

we know that

 Suri's coin purse

x=6, y=4

The ratio of dimes to quarters is

$\frac{x}{y} =\frac{6}{4}$

 Martha's coin purse

x=5, y=3

The ratio of dimes to quarters is

$\frac{x}{y} =\frac{5}{3}$

Compare the ratios

$\frac{6}{4}=\frac{5}{3}\\6(3)=4(5)\\18\neq 20$

therefore

The ratios are not equal
