Answer:

267 miles

please vote me brainliest. Thank you.

At the end of 12 weeks, Ai Mi has run 22 miles.

As mentioned in the question, Ai Mi just started a running plan where she runs 12 miles the first week and then increases the number of miles she runs by 5% each week.

The function which is in format f(x) =a^x  where a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).

here,
Let the total run be x, for 12 weeks
According to the question,

x = 12×(1 + 5%/100)¹²
x = 12(1.05)¹²
x = 21.55
x ≈ 22 miles

Thus, At the end of 12 weeks, Ai Mi has run 22 miles.

Answer:

5

Step-by-step explanation:

Divide the expression by r on both times; d/r=rt/r. You'll remain with t=d/r.

then substitute t=40/8 which equals to 5.

Answer:

  A. 14040 cubic inches

  B. 61 gallons

Step-by-step explanation:

The volume of a cuboid is given by the formula ...

  V = LWH

__

One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.

One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.

The volume of the fish tank is ...

  V = (39 in)(18 in)(20 in) = 14,040 in³

The volume is 14,040 cubic inches.

__

One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.

976 cups equals 61 gallons.

_____

Additional comment

One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

Answer:

g(f(x)) = 9x² + 15x + 4

Step-by-step explanation:

Given :

⇒ f(x) = 3x + 4

⇒ g(x) = x² - 3x

=============================================================

Solving :

⇒ g(f(x))

⇒ g(3x + 4) = (3x + 4)² - 3(3x + 4)

⇒ g(3x + 4) = (3x)² + 2(3x)(4) + (4)² - 9x - 12

⇒ g(3x + 4) = 9x² + 24x + 16 - 9x - 12

⇒ g(f(x)) = 9x² + 15x + 4

Answer:

C is 6.3

Step-by-step explanation:

We can apply the pythagorean theorum to find C.

A is 2, B is 6

A^2 + B^2 = C^2

2^2 + 6^2 = C^2

C^2 = 40

C = 6.32455532

Answer:

50.24

Step-by-step explanation:

Area = 200.96

Let's find the raidus from the area formula.

200.96 =  π · r^2

Divide both sides by  π !

64 = r^2

square root both sides

r = 8.

Now since we know the raidus we can find the circumferewnce.

-

c=2πr

c=2*3.14*8

c= 50.24

Answer:

first you have to order the numbers

8, 10, 13, 18, 23, 25, 26, 30

Median is between 18 and 23 so we add them then divide the sum by 2

Median: (18 + 23)/2 = 20.5

First Quartile is between 10 and 13 so we add them then divide the sum by 2

First Quartile: (10 + 13)/2 = 11.5

Third Quartile is between 25 and 26 so we add them then divide the sum by 2

Third quartile: (25 + 26)/2 = 25.5

Range: 30 - 8 = 22

Answer:

5

Step-by-step explanation:

Imagine a triangle with two of the corner points being the points (5,5) and (8,1)

The length and width would be 3 and 4 to find the hypotenuse (distance) do

3^2+4^2=x^2

9+16=x^2

25=x^2

x=5

[tex]here \: is \: your \: answer...[/tex]

Step-by-step explanation:

Let (x1,y1) = (5,5) and (x2,y2) = (8,1)

By using distance formula,

[tex]d \: = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]

[tex]d = \sqrt{ {(8 - 5)}^{2} + {(1 - 5)}^{2} } [/tex]

[tex]d = \sqrt{ {(3)}^{2} + {( - 4)}^{2} } [/tex]

[tex]d = \sqrt{9 + 16} [/tex]

[tex]d = \sqrt{25} [/tex]

[tex]d = 5 \: units[/tex]

Therefore, the distance between (5,5) and (8,1) is 5 units

Step-by-step explanation:

Number of males is

Number of males not enrolled

Number of females not enrolled

(a)

The table based on data is

                Enrolled        Not enrolled      Total  

Male            82                  36                     118    

Female        102                56                     158  

Total            184                 92                     276

(b)

Percentage of students were males that went to magic college

(c)

Percentage of females went to magic college

Answer:

a)  see below

b)  29.7%  (1 d.p.)

c)  64.6%  (1 d.p.)

Step-by-step explanation:

Part (a)

Using the given information to create a two-way table:

[tex]\begin{array}{|l|c|c|c|}\cline{1-4} & \sf Female & \sf Male & \sf Totals\\\cline{1-4} \sf Enrolled & 102 & 82 & \\\cline{1-4} \sf Not\:enrolled & & &\\\cline{1-4} \sf Totals & 158 & & 278\\\cline{1-4}\end{array}[/tex]

Calculations to fill the table:

Therefore:

[tex]\begin{array}{|l|c|c|c|}\cline{1-4} & \sf Female & \sf Male & \sf Totals\\\cline{1-4} \sf Enrolled & 102 & 82 & 184 \\\cline{1-4} \sf Not\:enrolled & 56 & 38& 94 \\\cline{1-4} \sf Totals & 158 &120 & 278\\\cline{1-4}\end{array}[/tex]

Part (b)

[tex]\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100[/tex]

Number of students who are male and enrolled = 82

Total number of students = 278

[tex]\begin{aligned} \implies \sf Percentage\:students\:enrolled & = \sf\left(\dfrac{82}{278}\right) \times 100\\& = \sf 29.7\%\:\:(1\:d.p.) \end{aligned}[/tex]

Part (c)

Total number of females enrolled = 102

Total number of females = 158

[tex]\begin{aligned} \implies \sf Percentage\:students\:enrolled & = \sf\left(\dfrac{102}{158}\right) \times 100\\& = \sf 64.6\%\:\:(1\:d.p.) \end{aligned}[/tex]

Answer:

Ingredient Percentage=Ingredient Weight/Total Flour x 100%

Step-by-step explanation:

For example, if a formula calls for 60 pounds of water and 100 pounds of flour, the baker's percent would be 60% water. If there are two types of flour being used, the combination of the weight of both flours will be 100%.

Answer:

length = 9 cm

Step-by-step explanation:

perimeter = p =26 cm

width = w=  4 cm

perimeter of a rectangle= 2*w+2*L

L= length

so we have:

26 = 2*(4) +2*L

26= 8 +2L

26-8 = 2L

18 = 2L

L= 18/2

L =9 cm = length

Answer:

1.65

Step-by-step explanation:

equation will be 12(f−0.55)=13.20

12f−6.6=13.20

12f = 19.8

f = 19.8/12 = 1.65

So, each can of soup at full price is $1.65.

Answer:

∠b=82°

Step-by-step explanation:

Step-by-step explanation:

6+10+8=24=iscolecles triangle

Answer:

A

Step-by-step explanation:

cosθ  = 8/10

θ = arcCos(8/10)

θ  =36.87

cot(36.87) = 8/x

1.33 = 8/x

x1.33 = 8

x = 6

Therefore , A is the correct Answer

That mean the new values of horsepower is equal to the previous value.

Answer:

-12

Step-by-step explanation:

Answer:

let the unknown number be 'x'

x + (-12) = -24

x = -24+12

x = -12

Answer:

x=10

y=[tex]10\sqrt{3}[/tex]

Step-by-step explanation:

Since there is a 30 degree angle, it is a special right triangle, 30 60 90 triangle. The shorter leg represents "a," the longer leg represents "a√3", and the hypotenuse represents 2a.

The triangle has a hypotenuse of 20 and we are trying to find x and y. x=10 because x is the opposite side of 30 degrees and x is half of the hypotenuse. y=[tex]10\sqrt{3}[/tex] because we already know the x value and y is opposite of 60 degrees. As mentioned before, the longer leg represents a√3.

Hope this helps and have a good day.  

Hey there!

(6^3 * 2^6) / 2^3

= (6 * 6 * 6 * 2 * 2 * 2 * 2 * 2 * 2) / 2 * 2 * 2

= (36 * 6 * 4 * 4 * 4) / 4 * 2

= (216 * 16 * 4) / 8
= 3,456 * 4 / 8

= 13,824 / 8

= 1,728

Looking for something that gives you the result of: 1,728

Option A.

= 2,985,984

2,985,984 ≠ 1,728

Option C. is also incorrect

Option D.
2^6 * 2^3

= 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

= 4 * 4 * 4 * 4 * 2

=======================================================

Explanation:

1 gallon = 4 quarts

2 gallons = 8 quarts

1/4 of 8 quarts = 2 quarts

She used 2 quarts for her bedroom and 3 for the hallway. Therefore, she used 2+3 = 5 quarts total.

That leaves 8 - 5 = 3 quarts for the living room.

Answer:

A: 3 Quarts

Step-by-step explanation:

1 gallon = 4 quarts

1/4 of 2 gallons = 1/4 × 2

                         = 1/2 gallon

⇒ 1/2 gallon = 2 quarts

Therefore, Mieko used 2 quarts of paint to paint her bedroom.

If she used 3 quarts to paint the hallway, then

⇒ total number of quarts used = 2 + 3 = 5 quarts

As she bought a total of 2 gallons of paint:

⇒ 2 gallons = 2 × 4 = 8 quarts

Therefore the remaining unused paint (to paint the living room) is:

⇒ total paint - used paid = 8 quarts - 5 quarts

                                         = 3 quarts
