The logarithm equation is equivalent to the exponential equation is c = log₃27

A logarithm is the power to which a number must be raised in order to get some other number.

Given that, exponential equation, [tex]3^{c}[/tex]=27

By the exponential form of logarithm:

[tex]x^{a} =m[/tex] then logarithm form is a = logₓ m

Therefore,

[tex]3^{c}[/tex]=27

Taking logarithm both sides,

[tex]3^{c}[/tex]=27

c = log₃27

Hence, the logarithm equation is equivalent to the exponential equation is c = log₃27

He washes 7 cars and gets $4.00 for each one :

So it's the number of cars times the money he gets for each one - 7 times 4 = 28

He fills 10 bags of leaves and gets $1.00 for each bag:

So it's the number of bags times the money he gets for each one - 10 times 1 = 10

Than you add the money from the cars to the money of bags : $10 + $28 =

uhhhhh, your question seems a bit unclear. could you make it a bit more readable?

1st and 5th are true.

The elevation of Smallville is calculated by multiplying the elevation of Longfield by 4. Longfield's elevation is -144 1/2 feet, which is equivalent to -289/2 as an improper fraction. Multiplying this by 4 gives the elevation of Smallville as -578 feet.

To find Smallville's elevation, we first take the elevation of Longfield, which is -144 1/2 feet below sea level. Since Smallville is 4 times farther below sea level than Longfield, we have to multiply the elevation of Longfield by 4.

First, convert -144 1/2 to an improper fraction: -144 1/2 = -289/2.

Now, multiply by 4:

(-289/2) × 4 = -289 × 2 = -578 feet

So the elevation of Smallville is -578 feet below sea level.

To find the 8th term of the pattern 1, 2, 5, 10, 17, analyze the differences between consecutive terms and find the common difference. Add that common difference to the 7th term to find the 8th term.

To analyze the pattern, we can observe that the difference between consecutive terms is increasing by 1 each time. Let's find the common difference:

From these differences, we can see that the common difference is increasing by 2 each time. So the difference between the 7th term and the 6th term would be 7 + 2 = 9. Using this pattern, we can find the 8th term:

Answer: D. About [tex]\frac{1}{2}[/tex] inches per hour.

Step-by-step explanation:

1. The city received [tex]12^{\frac{1}{4}}[/tex] inches of rain in [tex]25^{\frac{1}{2}}[/tex] hours.

2. Let's write the mixed number as decimal numbers:

[tex]12^{\frac{1}{4}}in=12.25in[/tex]

[tex]25^{\frac{1}{2}}h=25.5h[/tex]

3. To find the approximate rainfall rate in inches per hour, you must divide 12.25 inches by  25.5 hours, as following:

[tex]\frac{12.25in}{25.5h}=0.48\frac{in}{h}[/tex]

4. If you round the result to the nearest tenth, you obtain:

[tex]0.5\frac{in}{h}=\frac{1}{2}\frac{in}{h}[/tex]

5. Therefore, the answer is the option D.

The approximate rainfall rate is closest to 0.5 inches per hour therefore the correct answer is Option D.

To determine the approximate rainfall rate in inches per hour, we need to divide the total amount of rainfall by the duration over which it fell.

Using the formula for intensity:

The approximate rainfall rate is closest to 0.5 inches per hour, so the correct answer is Option D: about 1/2 inch per hour.

The total area is 21 (15+6=21)

Answer:

Area of the given figure is 21 square units

Step-by-step explanation:

Area of the rectangle formula is length times width

Area of the top rectangle  

Length = 5 and width = 3

So area of top rectangle =5 times 3 is 15 square units

Area of bottom rectangle  

length =2 and width =3

So area of bottom rectangle is 2 times 3 is 6 square units

Total area =[tex]15+6= 21[/tex] square units

The equation is [tex]\sqrt{x-2 \\ \\[/tex] -[tex]\sqrt{2x}[/tex] = [tex]\sqrt{x +2}[/tex]

Solution

Step 1:

Take square on both sides, we get

3x - 2[tex]\sqrt{x-2}[/tex][tex]\sqrt2{x}[/tex] -2 = x +2

Step 2:

Subtract 3x - 2 from both sides, we get

-2[tex]\sqrt{x-2} \sqrt{2x} = -2x + 4[/tex]

Step 3:

Again, square on both sides in order to get rid of the square root from the above equation, we get

[tex]8x^{2}-16x = 4x^{2} -16x +16[/tex]

Now we have to simplify it,

[tex]4x^{2} -16 = 0[/tex]

Step 4:

Now we have to solve this quadratic equation, in order to get the solution.

We get x = 2 and x = -2, When we verifying solution in the original given equation, the solution does not satisfy the equation.

Reason: We get negative number in the square root.

Therefore, it has no Roots.

Answer: b) No roots

Final answer:

The equation of a vertical line passing through the point (5,2) is x = 5. This type of line has an undefined slope and is defined by its x-coordinate, not dependent on the y-coordinate.

Explanation:

The equation of a vertical line that passes through the point (5,2) can be determined by understanding that a vertical line has an undefined slope and does not depend on the y-coordinate for its location on a coordinate plane. Instead, a vertical line's location is solely determined by its x-coordinate. Therefore, the equation of a vertical line that passes through (5,2) will have the same x-coordinate for all its points. This means that the equation for the vertical line through (5,2) is simply x = 5.

This equation is different from the conventional y = mx + b, which defines a straight line with a slope m and y-intercept b. In the case of a vertical line, the slope is undefined, and therefore, the standard linear equation cannot be applied. Instead, the equation is independent of y and is expressed only in terms of the constant x-value of the vertical line.

Answer:

The medium-sized can is the cheaper by the oz, and is $0.005 per oz. cheaper.

Step-by-step explanation:

Medium can:  $0.92/(46 oz) = $0.020/oz

Large can:   $3.60 / (144 oz) = $0.025/oz

Surprisingly, the medium can price per oz. is lower than that of the large can.  The difference is $0.005 per oz.

The medium can of tomato juice has the lower unit price at $0.02 per ounce, which is $0.005 lower per ounce than the large can's unit price of $0.025 per ounce.

To determine which can of tomato juice has the lower unit price, we need to calculate the cost per ounce for each can. For the medium can, we divide the cost by the number of ounces:

Medium can unit price = $0.92 / 46 ounces = $0.02 per ounce

For the large can, we perform a similar calculation:

Large can unit price = $3.60 / 144 ounces = $0.025 per ounce

The medium can has a lower unit price of $0.02 per ounce compared to the large can's unit price of $0.025 per ounce. The difference in unit price is $0.025 - $0.02 = $0.005, or half a cent per ounce.

On Saturday Nikki and Tyler walked to the local farmers market Nikki bought 8 apples for $6 dollars and Tyler brought 3 fewer apples than Nikki. How much did Tyler spend on apples?​

Tyler brought 8 apples - 3 apples = 5 apples.​

​To calculate the price of 5 apples we have to establish a proportion :

If 8 apples cost $6​

Then 5 apples will cost $X​

​X = 5apples * $6/8apples = $3.75

​Answer : Tyler spent on apples $3.75

N x 7 +3 = 45

N = 6    Hope this helps.

Hi GueenSilia,

Answer: (n x 7) + 3

45 - 3 = 42

42 / 7 = n

n x 7 + 3 = 45

----------------------------

42 / 7 = 6

6 x 7 = 42

42 + 3 = 45

n = 6

1. expand using place value.

337,060 = 300,000 + 30,000 + 7,000 + 000 + 60 + 0

Next, we will use exponents:

300,000 = 3 * 10^5

30,000 = 3 * 10^4

7,000 = 7 * 10^3

000 = 0 * 10^2

60 = 6 * 10

0 = 0 * 10^0

then after combing these exponents, we can write the number as:

337,060 = 3 * 10^5 + 3 * 10^4 + 7 * 10^3 + 0 * 10^2 + 6 * 10 + 0 * 10^0

Finally, removing the meaningless zeroes, we would end up with:

337,060 = 3 * 10^5 + 3 * 10^4 + 7 * 10^3 + 6 * 10
