Step-by-step explanation:
We have logb(8) = 3 and logb(0.5) = -1.
=> b³ = 8 and 1/b = 0.5
=> b = 2.
Therefore,
logb(4b) = log2(8) = 3.
Answer:
We have, logb(8)=3 and logb(0.5)=-1
→b³=8 and 1/b=0.5
→b=2
Therefore,
logb(4b) = log2(8)=3.
the length of a rectangle is 1 1/8 cm longer than the width. The perimiter of the rectangle is 13 1/4 cm. What are the width and length?
Answer:
Length = 3 7/8cm
Width = 2 3/4 cm
Step-by-step explanation
Let the length of the rectangle by L
Let the width be W
If the length of a rectangle is 1 1/8 cm longer than the width, then;
L = W + 1 1/8
L = W +9/8
perimeter of the rectangle = 2(L+W)
perimeter of the rectangle = 2(W + 9/8 + W)
13 1/4 = 2(2W + 9/8)
53/4 = 4W + 9/4
4W = 53/4 - 9/4
4W = 44/4
4W = 11
W = 11/4
Hence the width of the rectangle is 11/4 or 2 3/4 cm
Recall that L = W + 9/8
L = 11/4 + 9/8
L = (2(11) + 9)/8
L = 31/8
L = 3 7/8cm
hence the length is 3 7/8 cm
Answer:
Length = 3 7/8cm
Width = 2 3/4 cm

Step-by-step explanation:
At the market, you buy a soda for
$1.75 plus 3 bags of chips. If your
total was $4.72 without tax, how
much did each bag of chips cost?
WRITE AN EQUATION and solve.
Please hurry
Answer:
Each bag of chip costs 0.99 (99 cents)
Step-by-step explanation:
Soda = 1.75
Bag of chips = x
1.75 + 3x = 4.72
Subtract 1.75 from both sides;
3x = 2.97
Divide both sides by 3;
x = 0.99
Evaluate this expression. (6.4 × 103) ÷ (3.2 × 102) Express your answer in scientific notation.
The expression (6.4 × 10³) ÷ (3.2 × 10²) can be simplified to 0.2 × 10² in scientific notation.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
To evaluate this expression, you can first divide the numerator by the denominator:
(6.4 × 10³) ÷ (3.2 × 10²) = (6.4 / 3.2) × (10³ / 10²)
Next, you can simplify the fraction in the numerator:
(6.4 / 3.2) × (10³ / 10²) = 2 × (10³ / 10²)
Finally, you can simplify the fraction in the exponent:
2 × (10³ / 10²) = 2 × 10¹
2 × 10 = 20 = 0.2 × 10²
Therefore, in scientific notation, the expression (6.4 × 10³) ÷ (3.2 × 10²) can be written as 0.2 × 10².

Tom's Landscaping charges a flat fee for supplies, plus $25 per hour of work. Tom charged a customer $90 for a job that required 3 hours of work. Which equation would calculate the total amount Tom's Landscaping charges for a job that requires x hours of work?
Answer:
c=15+25x
Step-by-step explanation:
From the information given, you can say that the total amount Tom's Landscaping charges for a job would be equal to the flat fee plus the result of multiplying the charge per hour for the number of hours and this would be:
c=y+25x (1), where:
c is the total cost
y is the flat fee
x is the number of hours
Now, as you know that Tom charged a customer $90 for a job that required 3 hours, you can replace c with 90 and x with 3 and solve for y to find the flat fee:
90=y+25(3)
90=y+75
90-75=y
y=15
Finally, as you know that the flat fee is 15, you can replace this value in (1) to establish the equation that would calculate the total amount that Tom's Landscaping charges for a job that requires x hours of work:
c=15+25x
Shaunda answered 86% of the questions on her test correctly. If there were 50 questions on the test, how many did she NOT answer correctly?
Answer:
Shaunda answered 7 questions incorrect
Step-by-step explanation:
86% can be written as 86/100 or .86
When you multiply .86 or 86/100 by 50, you get 43 questions, which are how many questions she answered correctly.
50-43 = 7, so she answered 7 questions incorrectly.

If bricks are each 3 inches × 4 inches × 8 inches, how many bricks can be fit into a space which is 1 foot × 4 feet × 8 feet?
A 1 to 250
B 251 to 500
C 501 to 750
D 751 to 1000
E >1000
Answer:
The correct option is B.
Step-by-step explanation:
Consider the provided information.
The dimensions of bricks are in inches so convert foot into inches.
1 foot = 12 in
4 feet = 48 in
8 feet = 96 in
To calculate the number of bricks that fit into space we divide the space's volume by the volume of 1 brick.
[tex]\text{Number of bricks in space}=\dfrac{12\times 48 \times96}{3\times 4 \times8}[/tex]
[tex]\text{Number of bricks in space}=576[/tex]
Hence, 576 bricks can be fit into a space.
Therefore the correct option is B.

Answer:
x = (3 + 8y) / (y - 1)
Step-by-step explanation:
y = (x + 3) / (x - 8)
Make x the subject
y = (x + 3) / (x - 8)
Cross product
y * (x - 8) = (x + 3)
xy - 8y = x + 3
xy - x = 3 + 8y
Factorize the left hand side of the equation
x( y - 1) = 3 + 8y
Divide both sides by (y - 1)
x = (3 + 8y) / (y - 1)

6x^2+18x+12 is the right answer.A sum of $4000 is invested at 5.5% interest per year. Find the amount of time needed to double the money if it’s compounded monthly.
A) 12y
B) 12y 4m
C) 12y 8m
D) 13y
9514 1404 393
Answer:
C) 12y 8m
Step-by-step explanation:
The amount of principal P at compound monthly at interest rate r per year is given by ...
A = P(1 +r/12)^(12t) . . . . after t years
Here, we want to find t, so ...
A/P = (1 +r/12)^(12t)
log(A/P) = (12t)·log(1 +r/12)
t = log(A/P)/(12·log(1 +r/12))
Filling in the given values, we find t to be ...
t = log(8000/4000)/(12·log(1 +0.055/12)) ≈ 12.6315 ≈ 12 years 7.6 months
It will take about 12 years 8 months to double the money.

Due to the closure of the pulp and paper mill, the population of the small town is
decreasing at a rate of 12% annually. If there are now 2400 people living in the town,
what will the town's projected population be in eight years?
Answer:
The population will be 863 in the next eight years
Step-by-step explanation:
Here, we want to know the population of the town in 8 years, given the percentage decrease and the present population
The exponential equation to use is that;
P = I( 1 - r)^n
where P is the future population we want to calculate
I is the present which is 2,400
r is the percentage of decay given as 12% = 12/100 = 0.12
n is the number of years which is 8
Substituting these values, we have that
P = 2,400(1 - 0.12)^8
P = 2,400(0.88)^8
P = 863
