Answer:

1/625

Step-by-step explanation:

5^ -1 * 5^-3

The bases are the same, so we can add the exponents

5^ (-1+-3)

5^-4

We know that a^-b = 1/ a^b

1/5^4

1/625

Answer:

1/625

Step-by-step explanation:

When you multiply, you add the exponents. You now have $6^{-4}$ . This is equivalent to $\frac{1}{5^{4} }$ which equals 1/625.

The vertices of parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0). ABCD is reflected over the x-axis to create parallelogr

So, coordinates of QRST will be:

Q(2,−1),R(3,−4),S(5,−3),T(4,0)

Option D is correct.

Step-by-step explanation:

The vertices of given parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0).

ABCD is reflected over the x-axis to create parallelogram QRST

We need to find coordinates of QRST.

When the graph is reflected across x-axis, the x-coordinate remains the same, while y-coordinate becomes opposite i.e the sign is changed of the given coordinate.

So, coordinates of QRST will be:

Q(2,−1),R(3,−4),S(5,−3),T(4,0)

All the y-coordinates have been converted to their opposite signs

So, Option D is correct.

Sally is buying new school supplies she uses a 15% off coupon on the set of markers that was originally $3 she also bought some

timurjin [86]

[(100-15)/100 * $3]
= $2.55
$5.35 - $2.55
= $2.80 |80% paper|

80/100 = 2.80/x
4/5 = 2.80/x
4x = 14
x = 3.5

Original price of the paper = $3.50

A rectangular park is 40 m long and 24 m wide. A path 3m wide is constructed outside the park. Find the area of the path?

satela [25.4K]

Answer:

area of path is area of park with path - area of rectangular park

area of park =l x b= 45 x 30=1350 cm2

area of park with path is =45+2.5+2.5 x 30+2.5+2.5 = 1750cm2

area of path = 1750-1350=400 cm2
