A gannet flies 24 1/2ft above sea level. It increases its elevation by 5ft. Then it dives and changes its elevation by -47 2/3ft. After it dives, what is the gannets elevation relative to sea level?
Answer:
Its elevation relative to the sea level is -18 1/6 ft (it is 18 1/6 below sea level)
Step-by-step explanation:
Here, we want to calculate the elevation relative to sea level
The sea level refer to the base of the sea
We follow the flight procedure;
distance of 24 1/2 ft above sea level , then go further up by 5
its elevation now is 24 1/2 + 5 = 29 1/2 ft
A change of -47 2/3 ft
So the elevation now will be;
29 1/2 - 47 2/3
= 59/2 - 143/3
= (177-286)/6 = -109/6
= -18 1/6 ft

write an equation in slope-intercept form of the line that passes through the given points (-4,-2) (8,-2)
Answer:
y=-2
Step-by-step explanation:
First, find the slope using the slope formula: m=y2-y1/x2-x1
Plug the numbers into the equation and get 0
Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)
y+2=0(x+4)
Distribute and simplify to get the final answer.
y+2=0+0
y=-2

Which of the following is not a polynomial? 7−z 2p3q2− pq3 −5x+ 6y −3/x
The algebraic expression -5x+6y-3/x is not a polynomial.
The given polynomials are 7-z, 2p³q²-pq³ and -5x+6y-3/x.
What is the polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.
Here,
In 7-z has non-negative integer as exponent
So, it is a polynomial
In 2p³q²-pq³ has non-negative integer as exponent
So, it is a polynomial
In -5x+6y-3/x has negative integer as exponent, which is [tex]x^{-1}[/tex]
So, it is not a polynomial
Hence, the algebraic expression -5x+6y-3/x is not a polynomial.

Sara is ordering a circular rug for her living room. The area of the rug is 157 feet squared. What is the radius of the rug to the nearest tenth of a foot?
Answer:
157/ pi= 49.97 which is r squared, so the square root of 49.97= 7.06 or 7.1
so the radius of the rug is 7.1 ft

subtract 7x2+4x-9 from 5x2+10x-5
Answer:
2x^2-6x-4
Step-by-step explanation:
(7x2 + 4x - 9)
-(5x2 + 10x - 5)
=
7x^2-5x^2=2x^2
4x-10x=-6x
-9-(-5)=-4

The price of a television is $245. The sales tax rate is 8%. What is the amount of sales tax?
Answer:
$19.60
Step-by-step explanation:
245 is 100% of the total.
x is 108% of the total.
245/100 = x/108
245(108) = 26460
26460/100 = 264.6
264.6 - 245 = 19.6

You have 2,112 grams of a radioactive kind of mercury. How much will be left after 188 days if it's half-life is 47 days?
Answer:
132 gStep-by-step explanation:
Initial amount = 2112 gTime = 188 daysHalf-life = 47 days188 days / 47 days = 4 periods
Mercury left after 188 days:
2112 * (1/2)^4 = 2112* 1/16 =2112/16 =132 gIs the slope-intercept form and standard form of the same line equivalent?
Answer:
Linear equations can take several forms, such as the point-slope formula, the slope-intercept formula, and the standard form of a linear equation. These forms allow mathematicians to describe the exact same line in different ways.
