Good morning can y’all help me

Answer:

Well I got 9 log 10 (2)/ 3-3log10 (5)

Please correct me if I am wrong

Step-by-step explanation:

You have to apply the rule alogc (b) (b^a)

= [tex]\frac{log10(\sqrt{8))^{4}-log10((\frac{1}{2}))^{3}) } }{3-6log10(\sqrt{5}) }[/tex]

\frac{\log _{10}\left(\frac{\left(\sqrt{8}\right)^4}{\left(\frac{1}{2}\right)^3}\right)}{3-6\log _{10}\left(\sqrt{5}\right)}

Answer:

Step-by-step explanation: Am not sure if this is the answer you guys are looking for but my in 9th grade and this is how my math teacher taught me how to do it.

one chocolate cake=?=x

one lemon cake=?=y

$270 spent

need to buy total of 18 cakes

1-chocolate cake =$7

lemon cake = $5

cakes 18=x+y

money $110=$7x+$5y

When i graphed it on the demos calculator i got (10,8).

So 10= the number of chocolate cake brought and 4= the number of lemon cake brought

Step-by-step explanation:

y = 1 / (cx + a) - b

At the x-axis intercept, y = 0.

=> 1 / (cx + a) - b = 0

=> 1 / (cx + a) = b

=> b(cx + a) = 1

=> bcx + ab = 1

=> bcx = 1 - ab

=> x = (1 - ab) / (bc)

Hence the answer is Option B.

Answer:he ran 23 miles / XXIII miles more in February than March

Step-by-step explanation:

February = He ran XLVII ---   converting to numbers  becomes

XL= 40

VII=   7

XLVII= 47

In march he ran  XXIV--- converting to numbers becomes

XX= 20

IV= 4

XXIV= 24

Step 2

To find how many more he ran in February than March

Miles ran in February - Miles ran in March

47- 24=23.

Therefore he ran 23 miles / XXIII miles more in February than March

Answer:

[tex]\frac{2}{k+2}[/tex]

Step-by-step explanation:

Given the expression:

[tex]\frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}[/tex]

We are to find the product as shown:

[tex]= \frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{k^2-2^2} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{(k-2)(k+2)} * \frac{k-2}{2k+1}\\\\= \frac{2}{k+2} * 1\\\\= \frac{2}{k+2}[/tex]

Hence the required function is [tex]\frac{2}{k+2}[/tex]

Answer:

Slope = -4

Step-by-step explanation:

The slope is negative because the line is going down.

The line goes down 4 times and goes right once = 4

The required slope of the given graph would be - 4 which is a negative slope.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The graph is given in the question

Each square on a grid represents one unit on each side.

We have to determine the slope of the given graph D

According to the given graph, we take two points (4, 12) and (7, 0)

The slope of a line is defined as the gradient of the line.

It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

Slope m = (0 - 12)/(7 -3 )

Slope m = -12/3

Slope m = -4

Thus, the required slope of the given graph would be - 4

Answer:

The first amount invested at 3%= x = $7500

The second amount Invested at 5% = y = $17500

Step-by-step explanation:

Juelle had $25,000 to invest.

She invested part of that amount at 3% interest and part at 5% interest for one year.

The amount of interest she earned for both investments was $1100.

The formula for Simple Interest =

Principal × Rate × Time

Let us represent

The first amount invested at 3%= x

The second amount Invested at 5% = y

x + y= $25,000....... Equation 1

x = 25,000 - y

3% × x + 5% × y = $1100...... Equation 2

0.03x + 0.05y = 1100...... Equation 2

We substitute 25000 - y for x in Equation 2

0.03x + 0.05y = 1100

0.03(25000 - y) + 0.05y = 1100

750 - 0.03y + 0.05y = 1100

Collect like terms

- 0.03y + 0.05y = 1100 - 750

0.02y = 350

y = 350/0.02

y = 17500

Solving for x

x = 25,000 - y

x = 25000 - 17500

x = 7500

Therefore:

The first amount invested at 3%= x = $7500

The second amount Invested at 5% = y = $17500

Answer: There are 3 quarters , 9 dimes and 14 pennies.

Step-by-step explanation:

Let x= Number of quarters

Then, Number of dimes = 3x

Number of pennies = 3x+5

1 quarter = $ 0.25

1 dime = $0.10

1 penny = $ 0.01

So, Total amount = 0.25x+ 0.10(3x) + 0.01(3x+5)

= 0.25x+0.30x+ 0.03x+0.05

= 0.58x+0.05

Since Total amount = 1 dollar and 79 cents = $ 1.79  [1 cent = $ 0.01]

So,

[tex]0.58x+0.05=1.79\\\\\Rightarrow\ 0.58x= 1.74\\\\\Rightarrow x=\dfrac{1.74}{0.58}\\\\\Rightarrow x=3[/tex]

Thus, there are 3 quarters , 9 dimes , 14 pennies.

Step-by-step explanation:

there are 3 quarters , 9 dimes , 14 pennies.

Step-by-step explanation:

Answer:

The length of the road in the model is 60 m.

Step-by-step explanation:

Given: scale = 1:19

         real-life length of the road = 1.14 km

                                                      = 1140 m

Let the length of the road in the model be represented by d. A scale is a representative fraction that can be used to either increase or decrease the length of an object.

Scale = [tex]\frac{length on drawing}{actual length}[/tex]

The actual length is the real-life length given as 1140 m.

So that,

[tex]\frac{1}{19}[/tex] = [tex]\frac{d}{1140}[/tex]

19d = 1140

⇒ d = [tex]\frac{1140}{19}[/tex]

       = 60

Therefore, the length of the road in the model is 60 m.

Answer:

Let x equal “a number”

3x+5=9

Answer:

x = 4/3 or 1.33333333333333333333333(infinite 3)

Step-by-step explanation:

3 times a number =  3x

sum = addition

3x + 5 = 9

now balance equation, get numbers without x on same side. Subtract 5 from both sides, this will leave 3x on one side, and 9-5 on the other side.

3x = 4, now divide by 3 on each side to get x on one side

3x/3 = 4/3

x=4/3

4/3 = 1.33

3 x 1.33 +5 = 9

Answer:

8.9 meters

Step-by-step explanation:

this seems like a problem where you can use the pythagorean theorem:

you know one of the two legs (6m) and  the hypotenuse (9m), you must find the other leg

a^2 + 6^2 = 9^2

a^2 + 36 = 81

a^2 = 45

a = [tex]\sqrt{45}[/tex] or [tex]\sqrt{9}[/tex] · [tex]\sqrt{5}[/tex] which simplifies to be 3[tex]\sqrt{5}[/tex] or approx. 8.9 meters

Answer:

The cost of one rose is $11., and the cost of one geranium is $5.

Step-by-step explanation:

The cost of one rose bush and one geranium can be determined by the use of simultaneous equation. Let the cost of a rose bush be represented by x, and the cost of one geranium by y.

So that,

13x + y = 148 .............. 1

9x + 14 y = 169 ............... 2

From eqaution 1,

y = 148 - 13x ............... 3

substitute the value of y in equation 2

9x + 14(148 - 13x) = 169

9x + 2072 - 182x = 169

2072 - 169 = 182x - 9x

1903 = 173x

x = [tex]\frac{1903}{173}[/tex]

  = 11

x = 11

substitute the value of x in equation 3

y = 148 - 13x

  = 148 - 13(11)

  = 148 - 143

y = 5

x = 11, y = 5

Thus, the cost of one rose is $11., and the cost of one geranium is $5.
