In first figure there is reflection but it is not present in the second figure due to absence of bouncing back of ray of light.

In the first figure which is given the image shows the inverted image of the triangle A that is the reflection of Figure A . Reflection as per the definition is the bouncing back of light wave when it is touched to a thing or obstacle. It form a image in opposite direction.

So according to it Figure A in first pair is the reflection of figure B.

Whereas in figure B there is no reflection as the mirror image is shown and not the opposite or inverted image is there.

Mirror image is the image same as the object shown or kept. so its not the reflection of Figure A. In Pair 2 Figure A is not a reflection of Figure B.

Answer:

X=10, x=4

Step-by-step explanation:

first, divide 14 by 2, and square it; giving you

x^2-14x+(7)^2=-40

Because 7^2 is 49, you have to add 49 to the other side; giving you

x^2-14x+(7)^2=9

Then factor the left side; giving you (x-7)^2=9

Take the square root of both sides, giving you

(x-7)^2= plus or minus 3

Then solve to get two solutions, 10 and 4

Beverley has quarters and dimes in her pocket. She has 21 coins with a total value of $3.00. How many of each type of coin does

kondaur [170]

Answer:

Step-by-step explanation:

If all 21 coins were dimes, she'd have $2.10. But she has 90 more cents than that. Now for each coin that's a quarter, not a dime, she has 15 cents more. 90/15= 6. So there are 6 quarters, and 21-6 = 15 dimes.

Now we do it backwards to see if it's right. 6 quarters is $1.50, 15 dimes is $1.50, add those together and you get $3. So it's right. 6 quarters, 15 dimes.

(3.8 x 10 ^ -6) x (2.37 x 10 ^ -3)<br><br> Enter the answer in science notification

Black_prince [1.1K]

Multiply the coefficients and the powers of 10 with each other:

$(3.8 \times 10^{-6}) \times (2.37 \times 10^{-3}) = (3.8\times2.37) \times (10^{-6} \times10^{-3})$

The numeric part simply yields

$3.8\times2.37 = 9.006$

As for the powers of 10, you have to add the exponents, using the rule

$a^b \times a^c = a^{b+c}$

So, we have

$10^{-6} \times10^{-3} = 10^{-6-3} = 10^{-9}$

So, the final answer is

$9.006\times 10^{-9}$

The cost of cabin lodging is $25 per lodger. The equation y = 25x relates the total lodging cost (y) to the number of lodgers (x

dalvyx [7]

Answer: The unit rate is $25

Step-by-step explanation: We know that the cost of cabin lodging is 25 dollars per lodger.

Then the equation y = 25x models this relation.

Here the cost is y, and the number of lodgers is x.

We want to find the unit rate.

The actual equation should be in dollars, and the number of lodgers is just a scalar number.

so the equation should be:

y = $25*x

Now, the unit rate is defined as the rate with 1 in the denominator, in this case, is the price for each unit of x (lodgers) so is the price per lodger.

We already know that the price per lodger is $25, so the unit rate is $25.
