If 8 cents are needed to buy 10 pebbles, how many dollars are needed to buy 205 pebbles?
Answers
Answer:
Hello There!!
Step-by-step explanation:
If 8 cents=10 pebbles then do 205 divided by 10 which is 20.5 . So, 8×20.5=164 dollars.
(8×20.5=164) 8 cents=10 (10×20.5=205)
164 dollars=205
Therefore,the answer is 164 dollars.

What is a logarithm?The logarithm is exponentiation's opposite function in mathematics.
This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.

For the right triangles below, find the exact values of the side lengths a and c. If necessary, write your responses in simplified radical form.
Answers
Answer:
First triangle: [tex]a = 5\sqrt{2}[/tex], second triangle: [tex]c = \frac{8\sqrt{3}}{3}[/tex]
Step-by-step explanation:
In the first triangle, the value of [tex]a[/tex] is equal to the following trigonometric relation:
[tex]a = \frac{5}{\cos 45^{\circ}}[/tex]
[tex]a = \frac{5}{\frac{\sqrt{2}}{2} }[/tex]
[tex]a = \frac{10}{\sqrt{2}}[/tex]
[tex]a = \frac{10\sqrt{2}}{2}[/tex]
[tex]a = 5\sqrt{2}[/tex]
In the second triangle, we obtain the value of [tex]c[/tex] is equal to the following trigonometric relation:
[tex]c = 8\cdot \tan 30^{\circ}[/tex]
[tex]c = 8 \cdot \left(\frac{\sin 30^{\circ}}{\cos 30^{\circ}} \right)[/tex]
[tex]c = 8\cdot \left(\frac{\frac{1}{2} }{\frac{\sqrt{3}}{2} } \right)[/tex]
[tex]c = \frac{8}{\sqrt{3}}[/tex]
[tex]c = \frac{8\sqrt{3}}{3}[/tex]

Describe how to solve x−6=−12.
Answers
Answer:
See explanation.
Step-by-step explanation:
You have to use the inverse operation of -6 to get x by itself. So you have to add 6 to each side to get rid of the -6. And -12+6=-6. So, x=6.
Answer:
X is -6
Step-by-step explanation:
You have to add 6 to both sides like -6+6 and -12+6
-12+6=-6 which is the answer because -6-6 is -12
explain the differnce between -3^4 and (-3)^4

Answer:
[tex] { - 3}^{4} = - (3 \times 3 \times 3 \times 3) \\ {( - 3)}^{4} = ( - 3 \times - 3 \times - 3 \times - 3)[/tex]
The difference is that (-3)^4 has a negative 3 with parenthesis around it, which means that if it was in PEMDAS, you would work that out first.
