to prepare for a math test Eric study three times as long as Kendra and 1/2 as long as Geraldo. How long did Geraldo study if Ke
sp2606 [1]

Let

x---------> time in minutes used by Eric to study

y---------> time in minutes used by Kendra to study

z---------> time in minutes used by Geraldo to study

we know that

x=3y------> equation 1

x=0.5z

z=2x--------> equation 2

y=20 minutes --------> equation 3

substitute equation 3 in equation 1

x=3*20=60 minutes

find the value of z in equation 2

z=2*60=120 minutes

therefore

<u>the answer is</u>

The time in minutes used by Geraldo to study was 120 minutes

What two numbers can equal to 70 when added in 34 when subtracted.
lina2011 [118]

Answer:

18 and 52

Step-by-step explanation:

x + Y = 70

X - Y= 34 find the value of X interms of Y to find the answer:

X - Y= 34

X = 34 +Y

x + Y = 70

(34 + Y ) + Y = 70

34 + Y +Y = 70

2Y =70-34

2Y/2=36/2

Y = 18

x + 18 = 70

x=70 - 18

x= 52

check:

18 + 52= 70

52 - 18= 34

Four plumbers estimated the length of the radius of a cylindrical pipe. the estimates made by the plumbers are listed. • plumb
myrzilka [38]

The correct order of the radius  \sqrt{3} /11 \ , \pi /24 ,  3/25  ,  9/100 .

What is decreasing and increasing order?

A set of data is said to be in descending order, often referred to as decreasing order, when it is arranged from highest to lowest or largest to smallest.

The same concepts apply regardless of the type of information you're working with, whether it's letters, dates, sizes of things or any other group of information like numbers or dates.

For instance, arranging a group of numbers in descending order means doing so from biggest to smallest value.

Ascending order, often known as ascending order of importance, is the exact opposite of declining order.

The order of the items is lowest to highest value. The lowest value is placed first in the order, while the highest value is placed last.

The value of \sqrt{3} = 1.732

so \sqrt{3} / 11 = 1.732/11

=1732/11000

The value of pi = 3.14

so \pi / 24  = 3.14/24

= 314/2400
