Answer:
x = 2
Step-by-step explanation:
Given the equation as;
log 3 + log x - log(x + 1) = log 2
collect like terms
log x - log(x + 1) = log 2-1og 3
Re-write the equation by applying laws of logarithms in that when you subtract logs you divide the numbers/terms. This will give
log [ x / x+1 ] = log [2/3]
Cancel log on both sides to remain with;
x/ x+1 = 2/3
Apply cross-product
3{x} = 2{x+1}
3x = 2x + 2
3x-2x = 2
x = 2

A bag contains 2 red,5 blue,6 yellow, and 3 green crayons. What is the probability of selecting a red crayon, then without replacing it selecting an odd number that is (red, then green)
A.0
B.0.25
C.01
D.0.025
Answer: D.0.025
Step-by-step explanation:
Given: A bag contains 2 red,5 blue,6 yellow, and 3 green crayons.
Total crayons: 2+5+6+3=16
Probability of getting red crayon= [tex]\dfrac{\text{Number of red crayons}}{\text{Total}}[/tex]
[tex]=\dfrac{2}{16}=\dfrac18[/tex]
Without replacement, the probability of getting green crayon = [tex]\dfrac{\text{Number of green crayons}}{\text{Total}-1}[/tex]
[tex]=\dfrac{3}{15}=\dfrac15[/tex]
Required probability P(red then green)= [tex]\dfrac18\times\dfrac15=\dfrac1{40}=0.025[/tex]
Hence, correct option is D.0.025

The length of the missing side is: ?m
Answer:
85 ft
Step-by-step explanation:
for all right triangles, triangles with a 90 degree angle, the sides are equal to [tex]a^{2} + b^{2} = c^{2}[/tex] where c is the hypotenuse, or the longest side.
so... [tex]40^{2} + 75^{2} = c^{2}[/tex]
[tex]7225 = c^{2}[/tex]
c= 85

Answer:
y = - 1/2x - 3.5
Step-by-step explanation:
Can you find the y=mx+b?
Answer:
y=-2x+7
Step-by-step explanation:
Slope is y(2)-y(1)/x(2)-x(1)
I chose (1,5)(0,7) as my two points and got -2 as my slope
Then, I got (0,7) as my y-intercept because it was in the table.
So, the equation is y=-2x+7

A plumbing company charges a $95 fee for each job, plus $65 foreach hour that the job lasts. The expression 65h + 95can be used to calculate the cost of a job in dollars, where hrepresents the number of hours the job takes to complete. Part A.What is the cost of a job that lasts 1.5 hours?
Answer:
the answer would be 160H
The cost of a job that lasts 1.5 hours is $ 192.5
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The charge of each job by the plumbing company = $ 95
The charge on each hour for each job = $ 65
The equation for the cost of a job is = 65h + 95
where h is the number of hours for the job
Now , to calculate the cost of job that lasts 1.5 hours ,
substitute the value of h as 1.5
And , the equation becomes
= 65h + 95
= 65 ( 1.5 ) + 95
= 97.5 + 95
= $ 192.5
Hence , the cost of a job that lasts 1.5 hours is $ 192.5

Priscilla is drawing a map of her school that uses a scale in which 1.5 cm on the map represents 3 feet. If the first hallway has a length of 120 feet, what should the length of the hallway be on the map?
1 point
a. 40 cm
b. 60 cm
c. 30 cm
d. 45 cm
Answer: 60 cm
Step-by-step explanation: The conversion from 1.5 cm to 3 feet or 91.4 cm is 60.9 and 120 feet or 3657.6 cm divided by 60.9 is 60 cm so therefore the length of the hallway on the map should be 60 cm
Eiman borrowed $8000 at a rate of 14.5%, compounded semiannually. Assuming she makes no payments,
how much will she owe after 6 years?
Do not round any intermediate computations, and round your answer to the nearest cent.?
Answer:
1,717,351cents
Step-by-step explanation:
Using the compound interest formula
A = P(1+r/n)^nt
P = 8000
r = 14.5% = 0.145
n = 6/12 = 1/2 (semi annually)
t = 6years
Substitute
A = 8000(1+ 0.145/0.5)*(0.5)(6)
A = 8000(1+0.29)^3
A = 8000(1.9)^3
A = 8000(2.146689
A = 17,173.512
Hence the amount owned to the nearest cent is 1,717,351cents
The length of a rectangle is eight more than twice it's width. the perimeter is 96 feet. find the dimensions
Variables:
equation:
Solution:
Answer:
the length and width be 13.33 feet and 34.67 feet respectively
Step-by-step explanation:
The computation is shown below:
Let us assume the width be x
So, the length be 2x + 8
As we know that
The perimeter of the rectangle = 2(length + width)
96 = 2(2x + 8 + x)
96 = 4x + 16 + 2x
96 - 16 = 6x
80 = 6x
x = 80 ÷ 6
= 13.33 feet
So, the length would be
= 2 × 13.33 + 8
= 34.67 feet
Hence, the length and width be 13.33 feet and 34.67 feet respectively

The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day. The number of red carnations sold was 3 more than 2 times the number of pink carnations sold. Red Carnations were sold for $ 0.50 each and Pink Carnations sold for $0.75 exh . The club made $600.00 . How many of each carnation were sold?
Answer:
The number of :
Red carnations sold = x = 687 carnations
Pink carnations sold = y = 342 carnations
How many of each carnation were
Step-by-step explanation:
Let us represent
The number of :
Red carnations = x
Pink carnations = y
The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day.
The number of red carnations sold was 3 more than 2 times the number of pink carnations sold.
x = 3 + 2y .....Equation 1
Red Carnations were sold for $ 0.50 each and Pink Carnations sold for $0.75 exh . The club made $600.00 .
$0.50 × x + 0.75 × y = $600
0.5x + 0.75y = 600...... Equation 2
Using substitution method:
Let us substitute, 3 + 2y for x in Equation 2
0.5(3 + 2y) + 0.75y = 600
1.5 + y + 0.75y = 600
y + 0.75y = 600 - 1.5
1.75y = 598.5
y = 598.5/ 1.75
y = 342 carnations.
Solving for x
x = 3 + 2y .....Equation 1
x = 3 + 2(342)
x = 3 + 684
x = 687 carnations
Therefore, The number of :
Red carnations = x = 687 carnations
Pink carnations = y = 342 carnations
