Answer:

104 Inches

Step-by-step explanation:

Alyssa's blanket contains 7 pink stripes and 6 white stripes.

Total Number of Stripes =7+6=13

Since each stripe is 8 inches wide.

The width of Alyssa's blanket will be the product of the number of stripes by the width of each stripe.

Therefore:

Width = 13 X 8 Inches =104 Inches

Alyssa's blanket is 104 Inches wide.

The count of the equilateral triangle is an illustration of areas

There are 150 small equilateral triangles in the regular hexagon

<h3>How to determine the number of equilateral triangle </h3>

The side length of the hexagon is given as:

L = 5

The area of the hexagon is calculated as:

$A = \frac{3\sqrt 3}{2}L^2$

This gives

$A = \frac{3\sqrt 3}{2}* 5^2$

$A = \frac{75\sqrt 3}{2}$

The side length of the equilateral triangle is

l = 1

The area of the triangle is calculated as:

$a = \frac{\sqrt 3}{4}l^2$

So, we have:

$a = \frac{\sqrt 3}{4}*1^2$

$a = \frac{\sqrt 3}{4}$

The number of equilateral triangles in the regular hexagon is then calculated as:

$n = \frac Aa$

This gives

$n = \frac{75\sqrt 3}{2} \div \frac{\sqrt 3}4$

So, we have:

$n = \frac{75}{2} \div \frac{1}4$

Rewrite as:

$n = \frac{75}{2} *\frac{4}1$

$n = 150$

Hence, there are 150 small equilateral triangles in the regular hexagon

Find AT AND RC. 80 points

stealth61 [152]

Answer:

AT=6, RC=5

Step-by-step explanation:

Perpendicular bisector intersect at T that is the circumcenter.

since RT is a bisector or AC and AR=5 then RC=5

Circumcenter is equidistant from the vercices of the triangle so

AT≅BT≅CT

but CT is given to be CT=6 so AT=6

Hi there!

This should be easy,lol!

Answer:

$\sqrt[3]{-128} = \boxed{-128 \sqrt{3} }$ (Decimal: -221.702503)

$\sqrt[3]{162} = \boxed{162 \sqrt{3} }$ (Decimal: 280.592231)

$\sqrt[3]{-1000x^4} = \boxed{-1732.050808x^4}$

Sorry bout the explanation thingy. Their really long -.-!

But the last one is short so i'll put it for you!

Step-by-step explanation:

∴!For the last one!∴

$\sqrt[3]{-1000x^4}$

Simplifies to:

$= - 1732.050808 * x^4$

$= - 1732.050808 * ( x * x * x * x)$

$= - 1732.050808x^4$

Have a great day/night!

Can someone please help me ASAP

Dima020 [189]

Answer:

B ( 3.7 , -1.1)

Step-by-step explanation:

<h3>Given</h3><h3>x + y = 2.6.......equation 1</h3>

y = 3x - 12.2.......equation 2

Putting equation 2 I. equation 1

x + 3x - 12.2 = 2.6

4x = 2.6 + 12.2

4x = 14.8

Therefore x = 3.7

Now

y = 3 * 3.7 - 12.2

= 11.1 - 12.2

= -1.1
