Answer:

$8^7$

Step-by-step explanation:

$\dfrac{8^{15}}{8^7 \cdot 8} =$

Remember that $8 = 8^1$ .

$= \dfrac{8^{15}}{8^7 \cdot 8^1}$

When you multiply powers with the same base, add the exponents. Do this in the denominator.

$= \dfrac{8^{15}}{8^{7+1}}$

$= \dfrac{8^{15}}{8^{8}}$

When you divide powers with the same base, subtract the exponents.

$= 8^{15-8}$

$= 8^7$

WILL GIVE BRAINLIST 2 BEST ANSWER

kolezko [41]

Answer:

Step-by-step explanation:

We have been given side AB and BC

AB must be 6 as it is between 4 and -2 and that distance is 6 (we have been given no units).

BC must be also 6 as it starts at -4 and ends at 2.

Pythagoras Theorem = a^2 + b^2 = c^2 (^2 means squared)

C is the hypotenuse (longest side) and this is what we are trying to find...

6^2 + 6^2 = 36+36=72

So AC is 72, however we need to square root this to get our final answer.

72 doesn't square easily, so we will use surds. 72 is 36*2 and 36 is a square number hence why...

AC is 6 root 2

Hope this helps!

To make cherry turnovers, a cook cuts the dough into triangles with a base of 6 inches and a height of 3 inches. How many turnov

Inessa [10]

Answer:

24 turnovers can be cut from the rectangular piece of dough.

Step-by-step explanation:

Given:

A rectangular piece of dough is 12 inches wide and 18 inches long.

To make cherry turnovers, a cook cuts the dough into triangles with a base of 6 inches and a height of 3 inches.

Now, to find the number of turnovers can be cut from the dough.

So, we find the area of the triangle the cook cuts from the dough by putting formula:

Base (b) = 6 inches.

Height (h) = 3 inches.

$Area=\frac{hb}{2} \\\\Area=\frac{h\times b}{2} \\\\Area=\frac{3\times 6}{2} \\\\Area=\frac{18}{2} \\\\Area=9\ inches^2.$

Thus, the area of the triangle cut from the dough is 9 inches².

Now, to get the area of rectangular piece of dough by putting formula:

Length = 18 inches.

Width = 12 inches.

$Area=length\times width\\\\Area=18\times 12\\\\Area=216\ inches^2.$

Hence, the area of the rectangular dough is 216 inches².

Now, to get the number of turnovers can be cut from the rectangular piece of dough we divide the area of the rectangular dough by the area of the triangle cut from the dough:

$\frac{216}{9} \\\\=24\ turnovers.$

Therefore, 24 turnovers can be cut from the rectangular piece of dough.

Solve the system using substitution.

dedylja [7]

Okay sub equation 2 into equation 1:
so it becomes

x + 3x = 8
4x = 8
x = 2

then 2 + y = 8, therefore y = 6
So the answer is B
