Answer:

False

Answer:

<h2>FALSE</h2>

Step-by-step explanation:

The definiton of an absolute value:

|a|=\left\{\begin{array}{ccc}a&for&a\geq0\\-a&for&a

The absolute value of any real number is a non-negative number.

|-25| = -(-25) = 25 > 0

a chef uses 4 3/4 cups of broth for 10 servings of soup. How much broth is used in one serving of soup?
mafiozo [28]
Set up a proportion. 4 3/4 cup broth is to 10 servings as x cups broth is to 1 serving soup.

x= amount of broth in one serving

(4 3/4)/10= x/1
cross multiply

(4 3/4)(1)= 10x
convert 4 3/4 to improper fraction

(19/4)(1)= 10x

19/4= 10x
divide both sides by 10

19/4 ÷ 10= x
to divide fractions, multiply by reciprocal of 10

19/4 * 1/10= x
multiply numerators; multiply denominators

(19*1)/(4*10)= x

19/40 cup= x


ANSWER: 19/40 cup in one serving

Hope this helps! :)

Aaron says that all
Softa [21]

Answer:

NO

Step-by-step explanation:

Look at the figure attached below, we know that the area of the cone is the sum of area of circle part and cone part of the figure.

to find the surface area of the cone, first measure the radius of the base and find the area of the circle part by  formula \pi r^2. Then measure the side (slant height) length of the cone part and find the area of the cone part by the formula \pi rl.

Now the surface area of the cone is circumference of the circle plus area of the cone part.

i.e. surface\ Area\ of\ the\ cone=\pi r^{2}+\pi rl

From the above discussion we concluded that surface area of the cone does not depend only on the circumference of the base but also we need side length of the cone part as well thus <em>all  cones with a base circumference of 8 inches  will </em><em>not </em><em>have the same surface area.</em>
