Answer:

The answer to your question is:

x = 18

m∠ABD = 36°

m∠DBC = 54°

Step-by-step explanation:

m∠ABD + m∠DBC = 90°

2x + 3x = 90°

5x = 90°

x = 90/5

x = 18

m∠ABD = 2(18)

= 36°

m∠DBC = 3(18)

= 54°

A leprechaun places a magic penny under a girl's pillow. The next night there are 2 magic pennies under her pillow. Each night

Answer:

tn = 2097152 pennies
tn = 20971.52 dollars.

Step-by-step explanation:

A surprisingly large amount of money.

The question is "Does the amount of money just double or do the previous amounts add to the present amount?"

I think it just doubles. Not only that, but she can't spend any of it until night 22 is reached.

tn = a*2^(n - 1)
a = 1 She starts with 1 penny.
n = 22
tn = 1*2^(22 - 1)
tn = 1*2^21
tn = 2097152 pennies
tn = 20971.52 dollars.

Equality Properties

Step-by-step explanation:

Step 1: Define equation

4x - 5 = x - 1 + 3x

Step 2: Solve for x

Combine like terms: 4x - 5 = 4x - 1
Subtract 4x on both sides: -5 ≠ -1

Here we see that -5 does not equal -1.

∴ This equation has no solutions.

If a spherical ball is enlarged so that its surface area is 9 times greater than its original surface area, then the original ra

luda_lava [24]

The surface area of a sphere is $A = 4 \pi r^{2}$ and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.

For example, let us assign values.
Let A=90

A= 90*9 = 810

$90 = 4 \pi r^{2} 

$ and $810 = 4 \pi r ^{2}$

the first r is 2.68 and the second r is 8.03

then, $\frac{8.03}{2.68} = 2.99626$ or rounded off to 3.
