Answer:

Red

Step-by-step explanation:

Let x = number of laps and Let y = time taken to complete laps

She is able to run one lap in 7 minutes

Given this information we want to create an equation

the equation would be

7x = y

Now that we have created an equation we want to find how many laps she can run in 56 minutes.

The time is represented by 7 so we plug in 56 into y

so now we have

7x = 56

Finally we solve for x

*divide each side by 7*

56/7 = 8

7x / 7 = x

we're left with x = 8 meaning that she can run 8 laps in 56 minutes

In conclusion the answer is the Red one

Answer:

∠ B = 80.5°

Step-by-step explanation:

Since AB = AC then the triangle is isosceles with base angles congruent, so

∠ B = ∠ C , then

∠ B = [tex]\frac{180-19}{2}[/tex] = [tex]\frac{161}{2}[/tex] = 80.5°

Answer: The value of x is 6.

Step-by-step explanation:

In the figure we have two secants.

A secant is a line that intersects a circle in exactly two points.

For the figure attached below:

[tex]a\times b=c\times d[/tex]

So for the given figure,

[tex]x\times 8=4\times (4+8)\\\\\Rightarrow\ x=\dfrac{4\times12}{8}\\\\\Rightarrow\ x=6[/tex]

Hence, The value of x is 6.

x=6

Answer:

the first one

Step-by-step explanation:

Answer:

i ) $96120

ii ) Singular adult fee in 2012: $186.91

Step-by-step explanation:

( i )

To find the costs of all 560 peoples you:

Multiply the amount of people by the fee,

440 × 198 = $87120

120 × 120 = $9000

Add these go get the sum of member fees: $96120

( ii )

First calculate what 1% of the adult fee would be:

198 ÷ 100 = 1.98 = 1%

Then calculate what 0.1% of the fee:

1.98  ÷ 10 = 0.198 = 0.1%

Now multiply 5 by the value of 1% to get 5% :

5 × 1.98 = 9.9

Then multiply 6 by the  0.1% to get 0.6% :

0.198 × 6 = 1.188

Add these numbers together to get:

1.188 + 9.9 = $11.088 = 5.6%

Due to the fact this question is referring to money we will round this number 2 decimal places (as money does not exceed 2dp)

$11.09

We now subtract this from the 2013 fee to find out the 2012 fee

$198 - $11.09 = $186.91

$186.91 was the cost of a singular adult fee in 2012

She got it for 24% off

$500 - 24% = $380

Answer:

28

Step-by-step explanation:

2x28 = 56 -7 = 49

my answer has to be 20 characters long so don't mind the sentence with words

Answer:

t= 27

Step-by-step explanation:

2t-7=49

   +7+7

2t=56

t=27

Answer: zero real solutions

Step-by-step explanation: constants from equation are a= 2 , b= -4 and c= 7.

Discriminant D= b^2 -4ac = (-4)^2 -4x2x7= 16 - 56 = -40 <0 so there's no solution

For equation g(x)= 0

the formula is a^2+b^2=c^2

A and B are the sides doesn't matter which

C is always across from the right angle

so fill x in accordingly

4^2+3^2=x^2

16+9=

25= x^2

square root both 25 and x^2

25 becomes 5

x^2 becomes x

x=5

and just apply this to the other problems

Answer:

11. c > 5

12. option 1

Step-by-step explanation:

Answer:

Length of Rectangle is 3 cm less than twice the width

Area is 44 m2 ; let W = width;  2W - 3 = Length

Arect = L times W

44 = W ( 2W - 3 )

44 = 2W2 - 3W

0 = 2W2 - 3W - 44

Factoring

0 = ( 2W - 11 )( W +4)

2W - 11 =0   ;            W + 4 = 0

       W = 11/2                 W = -4  (width can not be a negative number)

Therefor: width is 11/2  and length is 8

Answer:

1/2

Answer: $1,467.80

Step-by-step explanation:

The formula for the future value given annual compounding is:

= Amount * ( 1 + rate) ^ number of years

The amount after 3 years at 5.5% is therefore:

= 1,250 * ( 1 + 5.5%)³

= 1,250 * 1.174241375

= $1,467.80

Answer:

[tex]\frac{3}{20}[/tex] = 0.15

Step-by-step explanation:

15 + 20 + 40 + 15 + 10 = 100

[tex]\frac{15}{100} = \frac{3}{20}[/tex] = 0.15

midpoint is (-1 and -1.5)

Answer:

Step-by-step explanation:

midpoint rule is    x2+x1 / 2  , y2+y1 / 2

where point one is P1 = (x1,y1) = (4,3)

and point two is P2 = (x2,y2) = -6,-6

for x   then,  -6+4 / 2 = -2 / 2   =  - 1

for y then,  -6+3 / 2 = -3 / 2  =  - [tex]\frac{3}{2}[/tex]

mid point is  ( -1 ,  - [tex]\frac{3}{2}[/tex] )

Answer:

x = 7 , y = 3 , or 7 free throws, and 3 3-pointers.

Step-by-step explanation:

James scored a total of 16 points during a basketball. Only free throws and 3-point baskets are used. Free throws = 1 point (x), 3-pointers = 3 points (y).

Set the equations:

16 = x + 3y

10 = x + y

First, isolate the variable x in the second equation. Divide y from both sides of the equation:

10 (-y) = x + y (-y)

x = 10 - y

Next, plug in 10 - y for x in the first equation:

16 = x + 3y

16 = (10 - y) + 3y

Simplify. Combine like terms:

16 = 10 - y + 3y

16 = 10 + (-y + 3y)

16 = 10 + 2y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, subtract 10 from both sides of the equation:

16 (-10) = 10 (-10) + 2y

2y = 16 - 10

2y = 6

Next, divide 2 from both sides:

(2y)/2 = (6)/2

y = 6/2 = 3

Plug in 3 for y in one of the equations:

16 = x + 3y

16 = x + 3(3)

16 = x + 9

Isolate the variable, subtract 9 from both sides of the equation:

16 (-9) = x + 9 (-9)

x = 16 - 9

x = 7

x = 7 , y = 3 , or 7 free throws, and 3 3-pointers.

Plug in to check:

16 = x + 3y

10 = x + y

16 = (7) + 3(3)

16 = 7 + 9

16 = 16 (True)

10 = (7) + (3)

10 = 10 (True).

Answer:

x = 7 , y = 3  or 7 free throws, and 3 3-pointers.

Answer:

FV= $1,397.1

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $1,250

Interest rate (i)= 2.25% compounded annually

Number of periods (n)= 5 years

To calculate the future value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 1,250*(1.0225^5)

FV= $1,397.1

Answer:

1.5

Step-by-step explanation:

Given:

The figure of a trapezium.

To find:

The measures of missing angle [tex]m\angle K, m\angle M[/tex].

Solution:

In the given figure [tex]JK\parallel ML[/tex].

If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.

[tex]m\angle J+m\angle M=180^\circ[/tex]         (Supplementary angles)

[tex]87^\circ+m\angle M=180^\circ[/tex]

[tex]m\angle M=180^\circ-87^\circ[/tex]

[tex]m\angle M=93^\circ[/tex]

Similarly,

[tex]m\angle L+m\angle K=180^\circ[/tex]         (Supplementary angles)

[tex]51^\circ+m\angle K=180^\circ[/tex]

[tex]m\angle K=180^\circ-51^\circ[/tex]

[tex]m\angle K=129^\circ[/tex]

Therefore, [tex]m\angle M=93^\circ[/tex] and [tex]m\angle K=129^\circ[/tex].

im not sure i think its 14.2

Answer:

15

Step-by-step explanation:

Total quantity of clay = 5 pound

Now, Reynolds  divides the clay into 1 third pound pieces.

this means each piece of clay weighs = 1/3 pounds

Therefore, number of pieces of clay = Total weight of clay/ weight of each piece

= 5/(1/3) = 15

Answer:

[tex]SA = 70\pi[/tex]

Step-by-step explanation:

Given

See attachment for cone

Required

The total surface area

This is calculated as:

[tex]SA = \pi r\² + \pi rl[/tex]

From the attached cone:

[tex]r = 5[/tex] -- radius

[tex]l = 9[/tex] --- slant height

So, we have:

[tex]SA = \pi * 5^2 + \pi * 5*9[/tex]

[tex]SA = 25\pi + 45\pi[/tex]

[tex]SA = 70\pi[/tex]

Answer:

The multiplicity of the root is 1

Step-by-step explanation:

Firstly, we need to understand what multiplicity is

By multiplicity, we simply refer to the number of times we have the certain root repeating itself

From the factorization, each of the given roots were only repeated once

That indicates that the given multiplicity is 1
