Jen is 4/10 meters taller than her sister. Her sister is 9/10 meters tall. How tall is Jen?
mariarad [96]

Add 4/10 to 9/10.

9/10 + 4/10 = 13/10

Simplify 13/10 into a mixed number by subtracting 10 from the numerator and turning it into a whole.

13/10 ⇒ 1 3/10

<h2>Answer:</h2>

<u>Jen is </u><u>1 3/10 meters</u><u> tall.</u>

A toxic radioactive substance with a density of 7 milligrams per square centimeter is detected in the ventilating ducts of a nuc
uysha [10]
For this case we have an equation of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease rate
 t: time in years.
 Substituting values we have:
 7 = A * (0.5) ^ ((1/20) * t)
 For t = 45 years we have:
 7 = A * (0.5) ^ ((1/20) * 45) 
 Clearing A:
 A = 7 / ((0.5) ^ ((1/20) * 45))
 A = 33.3
 Answer:
 
the density of the substance when it was deposited 45 years ago was:
 
A = 33.3 milligrams per square centimeter

Given two points M &amp; N on the coordinate plane, find the slope of MN , and state the slope of the line perpendicular to MN .
telo118 [61]

Answer:

Problem 1)       m = \dfrac{1}{4}     slope_{perpendicular} = -4

Problem 2)      m = \dfrac{1}{3}     slope_{perpendicular} = -3

Step-by-step explanation:

slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}

slope_{perpendicular} = \dfrac{-1}{m}

Problem 1) M(9,6), N(1,4)

slope = m = \dfrac{6 - 4}{9 - 1} = \dfrac{2}{8} = \dfrac{1}{4}

slope_{perpendicular} = \dfrac{-1}{\frac{1}{4}} = -4

Problem 2) M(-2,2), N(4,-4)

slope = m = \dfrac{4 - 2}{4 - (-2)} = \dfrac{2}{6} = \dfrac{1}{3}

slope_{perpendicular} = \dfrac{-1}{\frac{1}{3}} = -3
