Answer:
14.8 pounds
Step-by-step explanation:
Here, we want to get the actual value made of fat from the body weight
What we have to do here is to multiply the percentage by the body weight
Mathematically, we have this as;
18.8% of 127 pounds
= 18.8/100 * 127 = 14.80 pounds
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.

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)

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

Work Shown:
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

As a quick shortcut, anything in the form Ax+By = C will convert to y = (-A/B)x+(C/B) when you solve for y.
The slope is -A/B and the y intercept is C/B
convert 2x-y=-7 into slop-intercept form
Answer:
y=2x+7
Step-by-step explanation:
2x-y=-7
add y to each side
2x=-7+y
add 7 to each side
2x+7=y
and just flip the sides to make it look nice
y=2x+7

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

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 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.
