Answer:
0.527
Step-by-step explanation:
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term
The sequence given in the above Question is a geometric sequence.
The formula for the nth term of a geometric sequence is given as:
an = a × r ^n - 1
Where
a = First term
r = Common ratio
n = nth term
From the above question, we are asked to find the 7th term
Hence:
a = 6
Common ratio = Second term/first term
= 4/6 = 2/3
n = 7
The 7th term = 6 × (2/3 )^7 - 1
= 6 × (2/3)^6
= 6 × (2/3)⁶
= 0.5267489712
Approximately to the nearest thousandths the 7th term = 0.527

A shoe box has a length of 14.5 inches, a width of 7 inches, and a height of 5 inches. What is the surface area, in square inches, of the shoe box?
Answer:418 and heres why
Step-by-step explanation:
2(14.5 times 7 = 101.5 times 2 = 203
next
2(14.5 times 5 =72.5 times 2=145
then last
2(7 times 5= 35 times 2=70 add them all together then get 418
hope this help (:
The surface area of the shoe box is,
⇒ SA = 418 square inches
We have to given that,
A shoe box has a length of 14.5 inches, a width of 7 inches, and a height of 5 inches.
Since, We know that,
Surface area of cuboid is,
SA = 2 (lw + lh + hw)
Here, we have;
Length = 14,5
Width = 7 inches
Height = 5 inches
Hence, We get;
The surface area of the shoe box is,
SA = 2 (14.5 x 7 + 14.5 x 5 + 5 x 7)
SA = 2 (101.5 + 72.5 + 35)
SA = 2 (209)
SA = 418 square inches
Thus, The surface area of the shoe box is,
⇒ SA = 418 square inches

2x+3y = 18
3y = 18-2x ..... subtract 2x from both sides
3y = -2x+18
y = (-2x+18)/3 .... divide both sides by 3
y = (-2x)/3 + 18/3
y = (-2/3)x + 6

From the equation y−3=−2(x+1), identify the slope and a point on the line.
Answer:
slope = - 2, point on line = (- 1, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 2(x + 1) ← is in point- slope form
with slope m = - 2 and (a, b ) = (- 1, 3 )
The slope of equation y−3=−2(x+1) is -2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y−3=−2(x+1)
Using Slope- Intercept form
y= mx + b
So, the slope for the equation is -2.
Hence, the slope is -2.

If a thousand dollars is put into a bank account each year the account earns 7% simple interest in 4 years how much interest would it have gained
Answer:
$280
Step-by-step explanation:
According to the problem, calculation of the given data are as follows:
Principal amount (P) = $1,000
Rate of interest (r) = 7%
Time period (t) = 4 years
Here we use simple interest formula to calculate interest after 4 years.
I = P × r × t
By putting the value, we get
I = $1,000 × 7% × 4
= $70 × 4
= $280

What is the difference x/x^2+3+2 - 1/(x+2)(x+1)
Answer:
#4, x-1/(x^2+3x+2)
Step-by-step explanation:
x/(x^2+3x+2) - 1/((x+2)(x+1))
Convert the 1/((x+2)(x+1)) to 1/(x^2+3x+2)
now you have a common denominator to subtract
x/(x^2+3x+2) - 1/(x^2+3x+2)
results x-1/(x^2+3x+2)
Evaluate (2.4x10^4) (4.5x10^3)
Answer:
108000000x^2
Step-by-step explanation:
The given expression (2.4 × 10⁴) (4.5 × 10³) becomes 1.08 × 10⁸ after performing the operations.
To evaluate the expression (2.4 × 10⁴) (4.5 × 10³), we use the properties of exponents.
When multiplying numbers written in scientific notation, we multiply the coefficients and add the exponents.
(2.4 × 10⁴) (4.5 × 10³) = (2.4 × 4.5) × (10⁴ × 10³)
= 10.8 × 10⁷
Next, we simplify the result by adding the exponents since the base (10) is the same:
10.8 × 10⁷ = 1.08 × 10⁸
Therefore, the final result of the expression is 1.08 × 10⁸.

If the surface area of a sphere is 144pi square centimeters, what is the length of the radius of the sphere, in centimeters
Answer:
6cm
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
From the Question, we are given:
The surface area of a sphere = 144pi square centimeters = 144π cm²
The length of the radius of the sphere, in centimeters is calculated by:
4πr² = 144π
Divide both sides by 4π
4πr²/4π = 144π/4π
r² = 36
Square root both sides
√r² = √36
r = 6cm
Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.
