Answer:
162 5th term
Step-by-step explanation:
Answer:
5th term =162
Step-by-step explanation:
It is a geometric progression whose nth term = ar^n-1
Where a = 1st term =2
r=ratio of two term= -6/2=-3
n =nth term
So 5th term= 2x-3^5-1
=2x-3^4

which shows the price of a $35 video game after a mark up 27%
Answer:
Step-by-step explanation:
35*27%=9.45 mark up
35+9.45= 44.45 total cost
Answer:
The answer is $44.45
Step-by-step explanation:
You change the percent into a decimal so it would be .27 then multiply the .27 to the $35 and you will get $9.45. Then you add the $9.45 to the $35 and you will get the answer.

6.432 X 105
6.432 X 106
64.32 x 105
64.32 X 106
(9.6 X 6.7) X (103 X 10)
the equivalent expressions are:
(9.6*6.7)*(10³*10) 64.32*10⁴ 6.432*10⁵And the expression in scientific notation is the last one in the bullet points.
Which are the values equivalent to the given expression?Here we start with the expression:
(9.6*10³)*(6.7*10)
Where both numbers are in scientific notation, notice that we can write that product as:
(9.6*10³)*(6.7*10) = (9.6*6.7)*(10³*10) = 64.32*10⁴
Now, remember that in scientific notation, we only can have a single digit in the left of the decimal point, so we can rewrite:
64.32*10⁴ = 6.432*10⁵
So the equivalent expressions are:
(9.6*6.7)*(10³*10) 64.32*10⁴ 6.432*10⁵And the expression in scientific notation is the last one in the bullet points.

Several paint mixtures are made by mixing blue paint and white paint. Paint Colors Blue Paint White Paint Mixture A 5 cups 12 cups Mixture B 6 cups 6 cups Mixture C 4 cups 12 cups Mixture D 5 cups 6 cups Which mixture has the lowest ratio of blue paint to white paint? mixture A mixture B mixture C mixture D
Answer:
The mixture C is the correct option
Step-by-step explanation:
According to the given scenario, the calculation is as follows:
For Mixture A
Blue Paint - 5 cups
White Paint - 12 cups
The ratio between them is 5:12
For Mixture B
Blue Paint - 6 cups
White Paint - 6 cups
The ratio between them is 6:6 = 12:12
It came by multiply the numerator and denominator by 12
For Mixture C
Blue Paint - 4 cups
White Paint - 12 cups
The ratio between them is 4:12
For Mixture D
Blue Paint - 5 cups
White Paint - 6 cups
The ratio between them is 5:6 = 10:12
It came by multiply the numerator and denominator by 12
As it can be seen that in all four mixtures the denominator is the same so for calculating the lowest ratio we have to see the small value in the numerator
As it can be seen that there is a small value of 4
hence, the mixture C is the correct option

tan∅ = opposite over adjacentStep-by-step explanation:
Step 1: Set up equation
tan55° = 19/x
Step 2: Solve for x
Multiply x on both sides: xtan55° = 19Divide tan55° on both sides: x = 19/tan55°Evaluate: x = 13.3039Round: x ≈ 13.3And we have our final answer!
Answer:
13.3
Step-by-step explanation:
This is trigonometry
So for this one, we use a basic ratio. We need to use 19 and 55 degrees for the answer. We are given that the leg adjacent to the 55-degree angle is x and the opposite leg to the 55-degree angle is 19.
So we use tangent(opposite leg/adjacent leg) for this (TOA of SOH CAH TOA)
tan(55 degrees)=19/x
SO then solve for x and then evaluate using a scientific calculator and you should get 13.30394322

[tex]2 \: XCV \: \: angle = XWV \: \: arc[/tex]
[tex]XWV \: \: arc = 2 × XCV \: \: angle \\ [/tex]
[tex]XWV \: \: arc = 156°[/tex]
_________________________________
[tex]XWV \: \: arc + VCX \: \: arc = 360° \\ [/tex]
[tex]156° + VCX \: \: arc = 360°[/tex]
Subtract sides 156°
[tex]-156° + 156° + VCX \: \: arc = -156° + 360° \\ [/tex]
[tex]VCX \: \: arc = 204°[/tex]

Sum of the interior angles of XWVC equal 360° .
Thus in XWVC :

[tex](9y) + (17x) + (6y) + (78°) = 360° \\ [/tex]
[tex]15y + 17x + 78° = 360°[/tex]
[tex]15y + 17(6) + 78° = 360°[/tex]
[tex]15y + 102° + 78° = 360°[/tex]
[tex]15y + 180° = 360°[/tex]
Subtract sides 180°
[tex]15y + 180° - 180° = 360° - 180° \\ [/tex]
[tex]15y = 180°[/tex]
Divide sides by 15
[tex] \frac{15y}{15} = \frac{180}{15} \\ [/tex]
[tex]y = 12[/tex]

What is an equation of the line that passes through the point (−2,−2) and is parallel to the line 5x−y=4?
Answer:
It is -5
Step-by-step explanation:
Answer: y=5x+8
Step-by-step explanation:
first you solve for y:
5x - y = 4
-5x -5x
↓
[tex]\frac{-y}{-1}[/tex] = [tex]\frac{-5x+4}{-1}[/tex]
↓
y = 5x - 4
slope of given line: 5
slope of a parallel line: 5
plug in slope:
y = 5x + b
find b, which is 8 :)
plug it in!
y = 5x + 8

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.
From this graph we should determine two points so we can work out the slope. Let's take points (3, -4) and (6, -2).
The equation to find the slope is:
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's substitute in our values:
m = [tex]\frac{-2 - -4}{6 - 3}[/tex]
Remember that two negatives make a positive, let's solve for m:
m = [tex]\frac{2}{3}[/tex]
Okay, now we have the value of m. Now we need the value of b. We can determine this by looking at the graph and looking where the line passes through the y-axis. In this graph, we can see the line pass through the y-axis at point (0, -6).
Therefore we can determine that b = -6.
Let's substitute our value for m and our value for b into the slope-intercept formula:
y = mx + b
y = [tex]\frac{2}{3}[/tex]x + -6
There's your final answer! I hope this helps, have a great night. :)
