At Clint's next birthday, he will he will be twice the age of his cousin Elizabeth. Elizabeth is now two thirds the age of he br

tigry1 [53]

Ken:

Ken's Age = 18

Elizabeth:

Elizabeth's Age = 2/3 x Ken's age

Elizabeth's Age = 2/3 x 18

Elizabeth's Age = 12

Clint:

-Note: At Clint's next birthday. So we need to subtract 1 from the age.

Clint's Age = (2 x Elizabeth's Age) - 1

Clint's Age = (2 x 12) - 1

Clint's Age = 24 - 1

Clint's Age = 23 right now

Hope this helps!! :)

20/60+15/60=35/60> What dose it equal

stepladder [879]

Answer:

$\dfrac{7}{12}$

Step-by-step explanation:

1. Find the Greatest Common Factor of the numerator and denominator.

The prime factors of 35 are 5, 7, 35

The prime factors of 60 are 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The only common factor of 35 and 60 is 5.

2. Divide the numerator and denominator by the Greatest Common Factor.

$\dfrac{35}{60} = \mathbf{\dfrac{7}{12}}$

Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a star

n200080 [17]

Answer:

x=25/16

Step-by-step explanation:

Approximate Roots of Functions:

We are required to find the root of

$\displaystyle 5^{-x}+7=\ 2x+4$

Let's construct a function

$\displaystyle f(x)=\ 5^{-x}+7-2x-4$

Reducing:

$\displaystyle f(x)= 5^{-x}-2x+3$

The equation will have a solution when f(x)=0. We'll start from the approximate crossing point given in the graph (x=1.5)

$\displaystyle f(1.5)=5^{-1.5}-2(1.5)+3\ =0.089$

We'll move up on x=1.52

$\displaystyle f(1.52)=5^{-1.52}-2(1.52)+3=\ 0.046$

We are closer to the solution, let's try some more up

$\displaystyle f(1.54)=5^{-1.54}-2(1.54)+3=\ 0.0038$

This value x=1.54 is close enough to the solution of the original equation

From the options given, $\frac{25}{16}$ is the closest to our solution

$\boxed{Answer:\ x=25/16}$

The perimeter of a triangle is 27.1 feet. The sides of the triangle measure 9.8 feet, 10.9, and x feet

Novay_Z [31]

Answer:

x = 6.4 feet.

Step-by-step explanation:

If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).

Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,

And its sides are 9.8 feet, 10.9 feet, and x feet.

Therefore, 27.1 = ( 9.8 + 10.9 + x )

⇒ 27.1 = 20.7 + x

⇒ x = 6.4 feet (Answer)
