A High School Track Is Shaped As A Rectangle With A Half Circle On Either Side.A Rectangle Has A Length

Answers

Answer 1

Answer:

Option (3)

Step-by-step explanation:

Track is shaped as a rectangle with a semicircle on either side.

Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.

= 2(96) + 2πr

= [tex]192+2\pi (\frac{35}{2})[/tex]

= 192 + 35π

= 192 + 109.9

= 301.9 m

Since, Jake plans to run four laps.

Therefore, distance covered by Jake = 4 × 301.9

                                                              = 1207.6 m

Option (3) will be the correct option.

Answers

Answer:

30 degree

Step-by-step explanation:

x + x + 60 + 60 = 180 degree (being sum of interior angles of a triangle )

2x  120 = 180

2x = 180 - 120

x = 60/2

x = 30 degree

Answer:

I'm not quite sure but there is 180 degrees in a triangle and they give us two 60 degrees which add up to 120. So, I'm assuming x = 60 or either 30 degrees if we're solving for both the x's at the top.

Find the selling price of a $32 item after a 50% markup.
The selling price is $

Answers

Answer:

The seelijg price is $48.

Step-by-step explanation:

Markup is the amount a store adds to its cost of an item to come up with the selling price.

store cost + markup = selling price

If the markup on an item is 50%, then the store adds 50% of its cost to its cost to arrive at the selling price.

$32 + 50% of $32 =

= $32 + 0.5 * $32

= $32 + $16

= $48

Answer:

50% of 32 is 16 so it it 16$

Answers

Answer:

The trade discount is

$235.4

Step-by-step explanation:

Given data

Slacks= $22

Jumpers= $37

Number of orders for Slacks= 30

Number of orders for Jumpers= 40

Total cost

22*30=$660

37*40=$1480

=$2140

11% discount can be computed as

=11/100*2140

=$235.4

I will give brainliest. ​

Answers

Answer:

21 times 660 and then you will get the answer

Mark Brainliest please

Answer: 5 cm

Step-by-step explanation:

Curved Surface area of a cylinder formula :-

2.pie*r*h (where r is the radius)
Height = 21 cm

Curved Surface area of the cylinder = 660 cm2

So, 2* pie* r* h = 660 (Here I will assume pie to be 22/7)

And 2* 22/7 * 21* r = 660

And 132 * r = 660
Therefore, r = 660/132 = 5cnn

Therefore radius of the cylinder = 5 cm

Answers

Answer:

Options (1) and (5)

Step-by-step explanation:

Expression that defines the function is,

[tex]f(x)=\frac{1}{2}x+\frac{3}{2}[/tex]

Option 1

[tex]f(-\frac{1}{2})=\frac{1}{2}(-\frac{1}{2})+\frac{3}{2}[/tex]

          [tex]=-\frac{1}{4}+\frac{3}{2}[/tex]

          [tex]=-\frac{1}{4}+1+\frac{1}{2}[/tex]

          [tex]=1+\frac{1}{4}[/tex]

          [tex]=1\frac{1}{4}[/tex]

So, [tex]f(-\frac{1}{2} )=-2[/tex] is false.

Option 2

f(0) = [tex]\frac{1}{2}(0)+\frac{3}{2}[/tex]

     = [tex]\frac{3}{2}[/tex]

True.

Option 3

f(1) = [tex]\frac{1}{2}(1)+\frac{3}{2}[/tex]

    = [tex]\frac{3+1}{2}[/tex]

    = 2

Therefore, f(1) = -1 is false.

Option 4

[tex]f(2)=\frac{1}{2}(2)+\frac{3}{2}[/tex]

       [tex]=1+1+\frac{1}{2}[/tex]

       [tex]=2\frac{1}{2}[/tex]

Therefore, f(2) = 1 is false.

Option 5

f(4) [tex]=\frac{1}{2}(4)+\frac{3}{2}[/tex]

     [tex]=2+\frac{3}{2}[/tex]

     [tex]=\frac{4+3}{2}[/tex]

     [tex]=\frac{7}{2}[/tex]

True.

Options (1) and (5) are the correct options.

Answers

Part A

Answer: Choice B (upper right corner)

Explanation: Simply add the fractions mentioned, plus the g term, and that leads to a total of 4 gallons overall.

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

Part B

Answer: Choice A. 7/8 of a gallon (upper left corner)

Explanation:

The mixed number 1 & 1/2 converts to the improper fraction 3/2

Adding the fractions gets us to

(3/2) + (7/8) + (3/4)

(12/8) + (7/8) + (6/8)

(12+7+6)/8

25/8

So far, 25/8 of a gallon is accounted for. Add on the g to get (25/8)+g

Set this equal to the 4 gallons we want and solve for g

(25/8)+g = 4

g = 4 - (25/8)

g = (32/8) - (25/8)

g = (32-25)/8

g = 7/8

She needs 7/8 of a gallon of ginger ale

Answers

Answer:

12.25

Step-by-step explanation:

Expression

x^2 + 2y

x = 2.5

y = 3

x^2 = 6.25

2y = 3*2 = 6

x^2 + 2y = 6.25 + 6

x^2 + 2y = 12.25

Answer:

12.25

Step-by-step explanation:

We find the equation x^2 + 2y when x = 2.5 and y = 3.

We just have to replace x with 2.5 and y with 3 in the equation:

x^2 becomes 2.5^2

2y becomes 2 * 3 (When a variable is next to a number it means multiply)

So we get 2.5^2 + 2 * 3

We first do 2.5^2. 2.5^2 is the same as 2.5 * 2.5, which equals 6.25

Next we do 2 * 3 which equals 6

So it is 6.25 + 6, which is 12.25
