K is the midpoint of JL. JK = 2x + 5 and JL = 50.

Sergeu [11.5K]

Steve set the equation equal to 50 which is the entire length of JL. instead he should've set the equation equal to 25, since it's half of 50 and would represent the midpoint. he should've said 2x + 5 = 25

If Shannon wants to fill a spherical balloon so that it has a circumference of 8π in, how much air will she need to use to fill

lapo4ka [179]

The Volume of air needed for a spherical balloon of radius 4 inch and circumference 8π is 85.3 cubic inch

<h3>Volume of Sphere</h3>

Given Data

Circumference = 8π

Let us find radius

circumference = 2πr

8π = 2πr

8 = 2r

r = 8/2

r = 4 inch

Let us find the volume of the sphere

Volume = 4/3πr^3

Volume = 4/3* π*4^3

Volume = 4/3*π64

Volume = 256π/3

Volume = 85.3 cubic inch

Estimate the limit.

Bezzdna [24]

Answer:

a. 0.25

Step-by-step explanation:

The given expression is

$\lim_{x \to 2} \frac{x-2}{x^2-4}$

Factor the denominator using difference of two squares.

$\lim_{x \to 2} \frac{x-2}{(x-2)(x+2)}$

Cancel out common factors;

$\lim_{x \to 2} \frac{1}{(x+2)}$

We plug in 2 to get

$\lim_{x \to 2} \frac{1}{(x+2)}=\frac{1}{2+2}$

$\lim_{x \to 2} \frac{1}{(x+2)}=\frac{1}{4}=0.25$

Solving a decimal word problem using a linear equation of the for...

Sindrei [870]

Answer:

5 pounds of coffee

Step-by-step explanation:

Let the number of pounds of coffee bought be 'x'.

Given:

Value on gift card = $90

Value of coffee per pound = $8.09

Money left after buying coffee = $49.55

Now, using unitary method,

1 pound cost = $8.09

∴ 'x' pounds cost = $8.09x$

Now, Money left = Total money on gift card - Cost of coffee.

$49.55=90-8.09x\\\\8.09x=90-49.55\\\\8.09x=40.45\\\\x=\frac{40.45}{8.09}=5$

Therefore, Lashonda bought 5 pounds of coffee.
