Its x = 6
If (0.2)x = 2 and log 2 = 0.3010, then the value of x to the nearest tenth is:
(a) -10.0, (b) -0.5, (c) -0.4, (d) -0.2, (e) 10.0
Answer:
Solution:
(0.2)x = 2.
Taking log on both sides
log (0.2)x = log 2.
x log (0.2) = 0.3010, [since log 2 = 0.3010].
x log (2/10) = 0.3010.
x [log 2 - log 10] = 0.3010.
x [log 2 - 1] = 0.3010,[since log 10=1].
x [0.3010 -1] = 0.3010, [since log 2 = 0.3010].
x[-0.699] = 0.3010.
x = 0.3010/-0.699.
x = -0.4306….
x = -0.4 (nearest tenth)
Answer is option (c) -0.4
The value of x to the nearest tenth is -0.4
Logarithmic expressionGiven the following expressions
(0.2)x = 2 and log 2 = 0.3010
Taking log of both sides of (0.2)x = 2
log (0.2)x = log 2.
x log (0.2) = 0.3010,
x [log 2 - log 10] = 0.3010.
Note that log2 2 = 1
x [log 2 - 1] = 0.3010
x [0.3010 -1] = 0.3010, [since log 2 = 0.3010].
x[-0.699] = 0.3010.
x = 0.3010/-0.699.
x = -0.4306
Hence the value of x to the nearest tenth is -0.4

Step-by-step explanation:
John bought new headphones originally listed for $ 80.99 . They are \(35\%)| off. Which equation can be used to find the amount John will save?
Answer:
$28.35
Step-by-step explanation:
The headphones are $80.99 and are 35% off. To find the amount he will save, change the 35% to a decimal by moving it two times to the left, which is 0.35. Multiply 80.99 and 0.35 to get 28.3465. Round to get $28.35.
Evaluate. Express your answer to the nearest tenth, if necessary.
a) 5.3 ÷ (−8.4)
b) −0.25 ÷ (−0.031)
c) −5.3 + 2.4[7.8 + (−8.3)]

Suppose y varies directly with x. If y = 3 when x = 2, find y when x = 3.
A *9/2
B *2/3
C *3/2
D *2/9
Answer:
9/2
Step-by-step explanation:
Direct variation is
y = kx where k is the constant of variation
Substitute into the equation to find k
y=3 and x=2
3 = k*2
Solve for k
3/2 = k
y = 3/2 x
We know x =3
y = 3/2 * 3
y = 9/2
Answer:
A
Step-by-step explanation:
given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 2 , then
3 = 2x ( divide both sides by 2 )
[tex]\frac{3}{2}[/tex] = k
y = [tex]\frac{3}{2}[/tex] x ← equation of variation
When x = 3 , then
y = [tex]\frac{3}{2}[/tex] × 3 = [tex]\frac{9}{2}[/tex] → A
Solve for x.

How to find the median of 30 37 8
Answer:
to find the median, divide the odd number by 2 and round it up
for even numbers, only divide by 2.
Average the numbers with the number in the next highest position.
You have a median.
In this case, the median is 30.
The median of the numbers 30, 37, and 8 is 30.
To find the median of a set of numbers, you first need to arrange the numbers in either ascending or descending order and then determine the middle value.
Given the numbers: 30, 37, 8
Arrange the numbers in ascending order:
8, 30, 37
Determine the middle value:
Since there are three numbers, the middle value is the second number, which is 30.
