8 corners would be the answer
dimaraw [331]2 years ago
3 0

Answer:

8

Step-by-step explanation:

What an interesting question. From the outside, look at two faces opposite one another. You get 8 corners.

It cannot be any different from the inside. Imagine you are right at the center of the cube. Pick 2 faces that are opposite each other. You get 8 corners.

The answer is 8 from both places.

Each loop is of a different size, so we can't rotate the figure some angle x to have it line up with itself (0 < x < 360). Therefore, it doesn't have any rotational symmetry. That rules out choice A and choice C. Point symmetry is the same as saying "rotational symmetry of 180 degrees"

The figure doesn't have any line symmetry either. There is no line we can draw and reflect the figure over to have it match up with itself. That rules out choice B and points to choice D

Answer: D) It has no reflectional symmetry.

The sales tax on a $20 hammer is 7 percent, or $1.40. why is this tax a bigger burden for josh, who has a $15,000 income, than f
Bond [772]

Answer:

The ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

Step-by-step explanation:

As given

The sales tax on a $20 hammer is 7 percent, or $1.40.

As income of the  josh is 15000 and the income of the aaron is $150000 .

Now the ratio of the sales tax to the josh income .

\frac{Sales\ tax}{Josh\ income} = \frac{1.40}{15000}

\frac{Sales\ tax}{Josh\ income} = \frac{14}{15000\times 10}

\frac{Sales\ tax}{Josh\ income} = \frac{7}{75000}

In decimal form

\frac{Sales\ tax}{Josh\ income} = 0.000093\ (Approx)

Now the ratio of the  sales tax to the aaron income .

\frac{Sales\ tax}{aaron\ income} = \frac{1.40}{150000}

\frac{Sales\ tax}{aaron\ income} = \frac{14}{150000\times 10}

\frac{Sales\ tax}{aaron\ income} = \frac{7}{750000}

In decimal form

\frac{Sales\ tax}{aaron\ income} = 0.0000093\ (Approx)

Thus as the ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

Lana71 [14]
Newton's Law of Cooling

Tf=Ts+(Ti-Ts)e^(-kt)   where Tf is temp at time t, Ts is temp of surroundings, Ti is temp of object/fluid.  So we need to find k first.

200=68+(210-68)e^(-10k)

132=142e^(-10k)

132/142=e^(-10k)

ln(132/142)=-10k

k=-ln(132/142)/10

k≈0.0073  so 

T(t)=68+142e^(-0.0073t)  so how long until it reaches 180°?

180=68+142e^(-0.0073t)

112=142e^(-0.0073t)

112/142=e^(-0.0073t)

ln(112/142)=-0.0073t

t= -ln(112/142)/(0.0073)

t≈32.51 minutes
