Answer:
d = 637 ft below the surface
Step-by-step explanation:
Given
P = 14 + [tex]\frac{6}{13}[/tex] d
To find d when P = 308, then
14 + [tex]\frac{6}{13}[/tex] d = 308 ( subtract 14 from both sides )
[tex]\frac{6}{13}[/tex] d = 294 ( multiply by 13 to clear the fraction )
6d = 3822 ( divide both sides by 6 )
d = 637 ft
Answer:
637 feetStep-by-step explanation:
[tex]P=14+\dfrac6{13}d\\\\\\P=308\,,\qquad\qquad d=??\\\\\\308=14+\dfrac6{13}d\\\\ 308-14=\dfrac6{13}d\\\\294=\dfrac6{13}d\\\\d=294:\frac6{13}\\\\ d=294\cdot\frac{13}6\\\\d=637\,ft[/tex]

Answer:
[tex]\sqrt{80}[/tex]
Step-by-step explanation:
Pythagorean theorem (Gougu theorem) states that the hypotenuse squared is equal to the sum of the squares of two other sides. (a^2 = b^2 + c^2). Hence x^2 = 4^2 + 8^2 = 80.
As x squared is 80, x is the square root of 80.
You can factorise this into 4[tex]\sqrt{5}[/tex]
The half-life of a radioactive kind of neodymium is 11 days. If you start with 2,616 grams of it, how much will be left after 22 days?
Answer:
654 grams
Step-by-step explanation:
When you set up this equation you want the number of grams you start with, 2616, and the factor by which it is decreasing, which is half, or 1/2. Because the half life is 11 days, but you want to find the amount left over after 22 days, you can make 22/11 as the exponent on the 1/2. The equation should look like this : 2616(1/2)^22/11. With these kinds of equations you always want to multiply the starting value by the factor of increase/decrease, and raise that factor to the time eclipsed divided by the set time(like the 11 day half life).

Which of these systems of equations is shown in the graph?
Answer:
C) y = -x - 2; y = 4x + 3
Hope this helps
The solution is Option C.
The system of equations is y = - x - 2 ; y = 4x + 3
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 ,
Let the first equation be represented as A
Let the second equation be represented as B
Now , the value of A is
y = - x - 2 be equation (1)
Now , the value of B is
y = 4x + 3 be equation (2)
On simplifying the equation , we get
The point of intersection on the graph is ( -1 , -1 )
Substituting the values in the equation , we get
when x = -1 and y = -1
y = - x - 2
-1 = - ( -1 ) - 2
-1 = + 1 - 2
-1 = -1
So , the solution to the equation is ( -1 , -1 )
And ,
y = 4x + 3
-1 = 4 ( -1 ) + 3
-1 = -4 + 3
-1 = -1
So , the solution to the equation is ( -1 , -1 )
Hence , the equations are y = - x - 2 and y = 4x + 3

Determine in which direction the parabola below opens.
y=x2-7x + 18
Answer:
upwards
Step-by-step explanation:
Whether a parabola opens upwards or downwards depends on "a". (A as in ax^2+bx+c). If A is greater than zero it opens upwards. Less than zero it opens downwards. In this case, A is one so it opens up

A donation center has 44 small bins with 24 caned food in them they wanna give each food bank the same amount of food there are 4 food banks
Complete question :
A donation center has 44 small bins with 24 caned food in them they wanna give each food bank the same amount of food there are 4 food banks. How many cans should they give to each food bank?
Answer:
264 cans
Step-by-step explanation:
Number of bins = 44
Number of canned food per bin = 24
Total number of canned foods = (number of bins * number of canned food per bin)
Total number of canned foods = 44 * 24 = 1056
Food is to be distributed equally among 4 banks :
Number of food per bank = 1056 / 4 = 264

True or False? Will these lengths form a triangle?
Answer:
False.
Step-by-step explanation:
Since The angle sum property of traingke is 180°.
Answer:
No, these lengths will not form a triangle.
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of two sides must always be greater than the third side.
55 + 76 = 131
131 is not greater than 112.
Therefore, these lengths will not form a triangle.
