30% = 0.30
100 - 100(0.30) = 70

20% = 0.20
70 - 70(0.20) = 56

the answer is c

Answer:

C. $56

Step-by-step explanation:

We have been given that a DVD player with a list price of $100 is marked down 30%.

Let us find the price of DVD player after marked down by figuring out 70% (100-30) of $100.

\text{Price of DVD player after marking down}=\frac{70}{100}\times \$100

\text{Price of DVD player after marking down}=\$70

Therefore, the price of DVD player after marking down by 30% will be $70.

As John gets an employee discount of 20% off the sale price, so to find the amount paid by John we need to figure out 80% (100%-20%) of $70.

\text{The amount paid by John for DVD player}=\frac{80}{100}\times \$70

\text{The amount paid by John for DVD player}=8\times \$7

\text{The amount paid by John for DVD player}=\$56

Therefore, John paid $56 for the DVD player and option C is the correct choice.

Two circles with different radii have chords AB and CD, such that AB is congruent to CD. Are the arcs intersected by these chord
emmainna [20.7K]

The arcs intersected by these chords are not congruent.

Given that two circles with different radii have chords AB and CD, such that AB is congruent to CD.

Let r₁ and r₂ be the radii of two different circles with centers O and O' respectively.

Assuming that the each of the ∠АОВ  and ∠CO'D is less than or equal to π.

Then, we have isosceles triangle AOB and CO'D such that,

AO = OB = r₁,

CO' = O'D = r₂,

Let us assume that r₁< r₂;

We can see that arc(AB) intersected by AB is greater than arc(CD), intersected by the chord CD;

arc(AB) > arc(CD)      .......(1)

Indeed,

arc(AB) = r₁ angle (AOB)

arc(CD) = r₂ angle (CO'D)

So, we have to prove that ;

∠AOB >∠CO'D       ......(2)

Since each angle is less than or equal to π, and so

∠AOB/2  and ∠CO'D/2 is less than or equal to π

it suffices to show that :

tan(AOB/2) >tan(CO'D/2) ......(3)

From triangle AOB :

tan(AOB/2) = AB/(2*r₁)

tan(CO'D/2) = CD/(2*r₂)

Since AB = CD and r₁ < r₂ (As obtained from the result of (3) ), therefore, arc(AB) > arc(CD).

Hence, for two circles with different radii have chords AB and CD, such that AB is congruent to CD but the arcs intersected by these chords are not congruent.

Twenty less than 8 times a number is the same as 15 more than the number.
Nezavi [6.7K]
X-number
8x-20=15+x (subtract x)
7x-20=15 (then add 20)
7x=35 (then divide by 7)

I think you've got it from now, if not, just do 35 divided by 7. But go over the steps, so that you know how to do these types of questions.
