The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicate that you took 7350 steps today.

Let x be the actual number of steps. Then the equation will be given as,

(1 + 0.05)x = 7350

x = 7350 / 1.05

x = 7,000

The actual number of steps you took today will be

(1 + 0.05)x = 7350

x = 7350 / 1.05

x = 7,000

The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.

Answer:

Company C

Step-by-step explanation:

You divide the amount of money it all costs to the number of plushies they are selling it for.

A: 34.08/12 = $2.84 each

B: 42.90/15 = $2.86 each

C: 50.58/18 = $2.81 each

So C has the least amount of money spent for a greater amount of plushies so C would be the Best Buy.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.

here,
Sue deposited $1,500 into two different accounts. - She deposited $600 into an account that pays 7.5% simple interest. - She deposited $900 into an account that pays 6% compounded annually.

Investment 1,
Amount = P(1 + rt)
Amount = 600(1 + 0.075×5)
Amount = $825

Investment 2,
Amount = P(1 + rt)
Amount = 900(1 + 0.06×5)
Amount = $1170

Total balance = 825 + 1170
Total balance = $1995

Thus, the required total balance at the end of the 5 years is given as $1995.

Step-by-step explanation:

The 1000ths place is the 1 in 0.01

Answer:

A: 5

Step-by-step explanation:

4x + y = 17 --> y = 17 - 4x

5x + 2y = 22

<=> 5x + 2 . (17 - 4x) = 22

<=> 5x - 8x + 34 = 22

<=> 34 - 3x = 22

<=> 3x = 34 - 22 = 12

<=> x = 4

y = 17 - 4x = 17 - 4 . 4 = 17 - 16 = 1

So, x + y = 4 + 1 = 5

Answer:

Let the number be x.

8 times that number would be 8x, and taking away 18 from it 8x - 18. Knowing the result of doing this is 30, we can write the following equation:

8x - 18 = 30

And solve it. First we pass the -18 to the sight umming:

8x = 30 + 18

8x = 48

Then the 8 which is multiplying to the right dividig:

x = 48/8 = 6

Now we verify we have done it preporly:

8x - 18 = 30

8 * 6 - 18 = 30

48 - 18 = 30 TRUE

Answer:

x =6

Step-by-step explanation:

Translate into algebraic equation =

[tex]8(x)-18= 30\\= 8x-13=30[/tex]

Let's solve for x

[tex]\mathrm{Add\:}18\mathrm{\:to\:both\:sides}\\8x-18+18=30+18[/tex]

Simplify

[tex]8x=48[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}=\frac{48}{8}[/tex]

Simplify

Answer:

0.2 pounds of milk

0.3 pounds of sugar

1.5 pounds of flour

Step-by-step explanation:

If we have the ratio [tex]2:3:15[/tex], then we know that all of these ingredients together will be [tex]15+3+2=20[/tex]. If we want the whole thing to weight 2 pounds, then the total weight of everything else will be [tex]20\div2=10[/tex] percent of the original.

So,

[tex]2\cdot0.1=0.2\\\\3\cdot0.1=0.3\\\\15\cdot0.1=1.5[/tex]

We can confirm this is correct because [tex]1.5+0.3+0.2=2[/tex].

Hope this helped!

Step-by-step explanation:

Simple formula [tex]\frac{item ratio}{total ratio}[/tex]×total amount

milk powder;  ×2= 0.2 lb

sugar; [tex]\frac{3}{20}[/tex]×2= 0.3 lb

flour; [tex]\frac{15}{20}[/tex]×2= 1.5 lb

Answer:

[tex]f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}[/tex]

Step-by-step explanation:

So, we need to find the equation of a parabolic function that goes through the points (-3,67) and (-1,1) and has a stretch factor of 9.

In other words, we want to find a quadratic with a vertical stretch of 9 that goes through the points (-3,67) and (-1,1).

To do so, we first need to write some equations. Let's use the vertex form of the quadratic equation. The vertex form is:

[tex]f(x)=a(x-h)^2+k[/tex]

Where a is the leading coefficient and (h,k) is the vertex.

Since a is the leading coefficient, it's also our stretch factor. Thus, let a equal 9.

Also, we have two points. We can interpret them as functions. In other words, (-3,67) means that f(-3) equals 67 and (-1,1) means that f(-1) equals 1. Write the two equations:

[tex]f(x)=a(x-h)^2+k\\f(-3)=67=9((-3)-h)^2+k[/tex]

And:

[tex]f(x)=a(x-h)^2+k\\f(-1)=1=9((-1)-h)^2+k[/tex]

Now, we essentially have a system of equations. Thus, to find the original equation, we just need to solve for the vertex. To do so, first isolate the k term in the second equation:

[tex]1=9(-1-h)^2+k\\k=1-9(-1-h)^2[/tex]

Now, substitute this value to the first equation:

[tex]67=9(-3-h)^2+k\\67=9(-3-h)^2+(1-9(-1-h)^2)[/tex]

And now, we just have to simplify.

First, from each of the square, factor out a negative 1:

[tex]67=9((-1)(h+3))^2+(1-9(((-1)(h+1))^2)[/tex]

Power of a product property:

[tex]67=9((-1)^2(h+3)^2)+(1-9((-1)^2(h+1)^2))[/tex]

The square of -1 is positive 1. Thus, we can ignore them:

[tex]67=9(h+3)^2+(1-9(h+1)^2)[/tex]

Square them. Use the trinomial pattern:

[tex]67=9(h^2+6h+9)+(1-9(h^2+2h+1))[/tex]

Distribute:

[tex]67=(9h^2+54h+81)+(1-9h^2-18h-9)[/tex]

Combine like terms:

[tex]67=(9h^2-9h^2)+(54h-18h)+(81+1-9)[/tex]

The first set cancels. Simplify the second and third:

[tex]67=36h+73[/tex]

Subtract 73 from both sides. The right cancels:

[tex]67-73=36h+73-73\\36h=-6[/tex]

Divide both sides by 36:

[tex](36h)/36=(-6)/36\\h=-1/6[/tex]

Therefore, h is -1/6.

Now, plug this back into the equation we isolated to solve for k:

[tex]k=1-9(-1-h)^2[/tex]

First, remove the negative by simplifying:

[tex]k=1-9((-1)(h+1))^2\\k=1-9((-1)^2(h+1)^2)\\k=1-9(h+1)^2[/tex]

Plug in -1/6 for h:

[tex]k=1-9(-\frac{1}{6}+1)^2[/tex]

Add. Make 1 into 6/6:

[tex]k=1-9(-\frac{1}{6}+\frac{6}{6})^2\\ k=1-9(\frac{5}{6})^2[/tex]

Square:

[tex]k=1-9(\frac{25}{36})[/tex]

Multiply. Note that 36 is 9 times 4:

[tex]k=1-9(\frac{25}{9\cdot4})\\ k=1-\frac{25}{4}[/tex]

Convert 1 into 4/4 and subtract:

[tex]k=\frac{4}{4}-\frac{25}{4}\\ k=-\frac{21}{4}[/tex]

So, the vertex is (-1/6, -21/4).

Now, plug everything back into the very original equation with 9 as a:

[tex]f(x)=a(x-h)^2+k\\f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}[/tex]

And this is our answer :)
