Answer:
The area is 90 sq. cm
Step-by-step explanation:
Given
The variation can be represented as:
[tex]A\ \alpha\ l * w[/tex]
Area = 60, when l = 4 and w = 3
Required
Find Area, when l = 6 and w = 3
Represent the variation as an equation
[tex]A = k(l * w)[/tex]
Where k is the constant of variation.
Substitute 60 for A, 4 for l and 3 for w
[tex]60 = k * (4 * 3)[/tex]
[tex]60 = k * 12[/tex]
Make k the subject
[tex]\frac{60}{12} = k[/tex]
[tex]5=k[/tex]
[tex]k=5[/tex]
To get the value of Area when l = 6 and w = 3.
Substitute 5 for k, 6 for l and 3 for w in [tex]A = k(l * w)[/tex]
[tex]A = 5 * 6 * 3[/tex]
[tex]A = 90[/tex]
The area is 90 sq. cm

What is the best way to answer this mixed number 7 3/4 + 1 5/6
9514 1404 393
Answer:
9 7/12
Step-by-step explanation:
12 is a suitable common denominator.
(7 3/4) + (1 5/6) = (7 9/12) + (1 10/12) = (7+1) +(9/12 +10/12)
= 8 + 19/12 = 9 + 7/12 . . . . . . change 19/12 to 1 7/12
= 9 7/12

My calculator works with mixed numbers very nicely, as many graphing calculators do.
Step-by-step explanation:
convert the fractions to whole numbers. the first one is:
4 × 7, then add 3, or 31/4.
the second one is 6 × 1, then add 5, or 11/6.
then you have 31/4 + 11/6. then you make a common denominator, which would be 12 (6 and 4 both go into 12).
3 × 31 = 93, so then the first fractions becomes:
93/12
second fraction becomes 11 × 2 = 22, then:
22/12.
so now you have 93/12 + 22/12 = 115/12, or 9 7/12
A hotel manager is adding a tile border around the hotel's rectangular pool. let n represent the width of the pool, in feet. the length is 3 more than 3 times the width, as shown. Write two expressions that represent the perimeter of the pool.
Answer:
[tex]2(4n+3)[/tex]
[tex]8n+6[/tex]
Step-by-step explanation:
We are given that
Let n represent the width of pool
Length of pool=[tex]3n+3[/tex]
We have to find two expression which represent the perimeter of the pool.
We know that
Perimeter of rectangle=[tex]2(l+b)[/tex]
Where l=Length of rectangle
b=Width of rectangle
Using the formula
Perimeter of pool=[tex]2(n+3n+3)[/tex]
Perimeter of pool=[tex]2(4n+3)[/tex]
Perimeter of pool=[tex]8n+6[/tex]
Hence, two expressions that represent the perimeter of the pool is given by
[tex]2(4n+3)[/tex]
[tex]8n+6[/tex]
simplify (-4/5)^9/(-4/5)^10
Answer:
[tex]-\frac{5}{4}[/tex]
Step-by-step explanation:
We are given two fractions and are asked to simplify it.
So
[tex](-\frac{4}{5} )^9 / (-\frac{4}{5} )^{10}[/tex]
We can follow the exponent rule of subtracting them since both fractions are the same value.
[tex](-\frac{4}{5} )^{9-10}[/tex]
[tex](-\frac{4}{5} )^{-1}[/tex]
Now do the negative exponent rule :
[tex]\frac{1}{-\frac{4}{5} }[/tex]
Move the negative in between the fraction :
[tex]-\frac{1}{\frac{4}{5} }[/tex]
And apply the fraction switcharoo :
[tex]\frac{5}{4}[/tex]

Answer:
[tex]x = \frac{y}{3} - \frac{5}{3}[/tex]
Step-by-step explanation:
Given
[tex]y = 5 + 3x[/tex]

Solve for x
Subtract 5 from both sides
[tex]y-5 = 5 -5+ 3x[/tex]
[tex]y-5 = 3x[/tex]
Divide through by 3
[tex]\frac{y}{3} - \frac{5}{3} = x[/tex]

A bacteria with an initial size of 180in2 grows by 27% every minute. What will the size of the bacteria be after 8hours
Answer:
The size of the bacteria after 8 hours will be of [tex]1.2 \times 10^{52}[/tex] squared inches.
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
[tex]F(t) = F(0)(1+r)^{t}[/tex]
In which F(0) is the initial value and F is the growth rate.
A bacteria with an initial size of 180in2 grows by 27% every minute.
This means that [tex]F(0) = 180, r = 0.27[/tex]. So
[tex]F(t) = F(0)(1+r)^{t}[/tex]
[tex]F(t) = 180(1+0.27)^{t}[/tex]
[tex]F(t) = 180(1.27)^{t}[/tex]
In which t is measured in minutes,
What will the size of the bacteria be after 8hours
8 hours has 8*60 = 480 minutes, so this is F(480).
[tex]F(480) = 180(1.27)^{480} = 1.2 \times 10^{52}[/tex]
The size of the bacteria after 8 hours will be of [tex]1.2 \times 10^{52}[/tex] squared inches.

Step-by-step explanation:
A data scientist studying a manufacturing process classifies each item produced by the process as either Poor, Acceptable, or Excellent. Assume that the classes of different items are independent of each other and that each item falls into the classes according to the following probabilities:
Poor Acceptable Excellent
0.25 0.6 0.15
The data scientist receives three items produced by the manufacturing process.
Find the chance that:
a. all of items are Acceptable
b. none of the items is Acceptable
c. at least one of the items is Excellent
d. not all of the items are Excellent
e. there is one item of each class
Answer:
0.214 ; 0.064 ; 0.3859 ; 0.9966 ; 0.135
Step-by-step explanation:
Given the distribution :
Poor ___ Acceptable ____ Excellent
0.25 _____ 0.6 _________ 0.15
The data scientist receives three items produced by the manufacturing process.
Find the chance that:
a. all of items are Acceptable
0.6 * 0.6 * 0.6 = 0.6^3 = 0.214
b. none of the items is Acceptable
P(not acceptable) = 1 - p(acceptable) = 1 - 0.6 = 0.4
0.4 * 0.4 * 0.4 = 0.4^3 = 0.064
c. at least one of the items is Excellent
P(atleast one) = 1 - P(none)
P(not excellent) = 1 - 0.15 = 0.85
P(none is excellent) = 0.85^3 = 0.614125
Hence,
P(atleast one is excellent) = 1 - 0.614125 = 0.3859
d. not all of the items are Excellent
P(not all) = 1 - p(All)
P(all excellent) = 0.15^3 = 0.003375
P(not all are excellent) = 1 - 0.003375 = 0.9966
e. there is one item of each class:
P(poor) * p(acceptable) * p(excellent) * (number of classes)!
0.25 * 0.6 * 0.15 * 3!
= 0.135

find the positive zero of the function f(x)=x^(2)-5x-7 and round two decimal places
Answer:
6.14
Step-by-step explanation:
Given the function f(x)=x^(2)-5x-7, when f(x) = 0
x^(2)-5x-7 = 0
Using the general formula
x = 5±√5²-4(-7)/21(1)
x= 5±√25+28/2
x = 5±√53/2
x = -5±7.28/2
x = 5+7.28/2 and 5-7.28/2
x = 12.28/2 and -2.28/2
x = 6.14 and -1.14
Hence the positive zero is 6.14
