Answer:

Jordan ran for 720 Seconds.

Step-by-step explanation:

X minutes multiplied by 60 gives you how many seconds. X is your variable, meaning it stands in for a number. Since you have 12 minutes, you would replace x with 12, giving you 12 multiplied by 60= seconds. 12x60=720, meaning Jordan ran for 720 seconds.

wel

Given :

A one-year membership to a gym costs $725.

The registration fee is $125.

To Find :

How much new members pay each month.

Solution :

Remaining fee = Total fee - Registration fee

R = $( 725 - 125 )

R = $600

Amount of fee paid monthly is :

C=\dfrac{R}{12}\\\\C = \dfrac{600}{12}\\\\C = \$50

Therefore, monthly fee is $50.

Hence, this is the required solution.

Evaluate the function f(x)=x^2+2x+3 at the given values of the independent variable and simplivy
tatyana61 [14]

Answer: i) f(-9)= 66

ii) f(x+1)=x^2+4x+6.

iii) f(-x)=x^2-2x+3

Step-by-step explanation:

The given function : f(x)=x^2+2x+3.

i) For f(-9) , the independent variable is x= -9.

Put x= -9 in given function , we get

f(-9)=(-9)^2+2(-9)+3

=81-18+3=66

Thus ,  f(-9)= 66

ii) For f(x+1) , the independent variable is x= x+1.

Replace x  by x+1 in given function , we get

f(x+1)=(x+1)^2+2(x+1)+3.

=(x^2+1+2x)+2x+2+3  [\because\ (a+b)^2=(a^2+b^2+2ab)]

=x^2+1+2x+2x+5

=x^2+4x+6

Thus ,  f(x+1)=x^2+4x+6.

iii)For f(-x) ,  the independent variable is x=-x.

Replace x  by -x in given function , we get

f(-x)=(-x)^2+2(-x)+3.

=x^2-2x+3  [∵ (+)(-)=(-)]

Thus , f(-x)=x^2-2x+3

Mackenzie picked 20 strawberries, 5 blueberries, and 15 raspberries. What was the ratio of the number of strawberries to the tot
Korvikt [17]

Answer:

20:40

Step-by-step explanation:

Because part of the ratio is the total number of berries, we need to add up all of the berries.

20+15+5=40

The number of strawberries picked is 20, so the ratio is 20:40

Hiya please leave formulas x
Mekhanik [1.2K]

Answer:

angle c = 107°

angle b = 107°

angle a = 73°

Step-by-step explanation:

Given:

Two line XY and WZ intersect each other and make four angle [a, b, c, d]

Given that Angle d = 73°

Find:

angle a

angle b

angle c

Computation:

We know that angle c and angle d situated on same line XY

So,

angle c + angle d = 180°

angle c + 73° = 180°

angle c = 107°

We know that angle b and angle d situated on same line WZ

So,

angle b + angle d = 180°

angle b + 73° = 180°

angle b = 107°

angle a and angle d are vertical opposite angle

So,

angle a = angle d

angle a = 73°
