Answer:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.
Step-by-step explanation:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.
Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.
Let x represent the number of bull shark teeth.
So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.
18 = 6 + 8 + x
18 = 14 + x
subtracting 14 from both sides, we have
18 - 14 = 14 - 14 + x
4 = 0 + x
4 = x
x = 4
So, the number of bull shark teeth is 4.

Prism A is a triangular prism. The triangular base has a base of 7 meters and height of 9 meters. The prism has a height of 4 meters. Prism B is a rectangular prism with length of 8 meters, width of 2 meters, and height of 8 meters. Which prism has the least volume? Prism '
*see attachment for the diagram of the prisms
Answer:
Prism A
Step-by-step explanation:
✔️Volume of triangular prism (Prism A) = ½×bhl
b = 7 m
h = 9 m
l = 4 m
Volume of Prism A = ½ × 7 × 9 × 4
Volume of Prism A = 126 m³
✔️Volume of rectangular prism (Prism B) = L × W × H
L = 8 m
W = 2 m
H = 8 m
Volume of Prism B = 8 × 2 × 8 = 128 m³
✔️Prism A has the least volume
Answer:
Prism A has the least volume!

How do you graph a quadratic function?
Answer:
Step-by-step explanation:
Compare the equation with the standard form, y=ax2+bx+c . Since the value of a is positive, the parabola opens up.
So, y=0 implies, by the zero product property, x+4=0 or x−2=0 .
Substitute x=−1 in the equation y=−x2−2x+8 to find the y -coordinate of the vertex.

Answer:
k = -10.5
Step-by-step explanation:
k + 7.5 = -13
Subtract 7.5 from both sides
k + 7.5 - 7.5 = -13 - 7.5
k = -20.5

Can a solution to this equation be 3, because then both sides would have divide by 0?
Answer:
Step-by-step explanation:
If we multiply x - 7 by x - 3, we get x^2 - 10x + 21. This shows that the LCD is x^2 - 10x + 21, or (x - 7)(x - 3). Let's convert each of the two fractions on the right to their equivalents, with the LCD in the denominator.
Multiplying both the numerator and the denominator of 6/(x - 7) by (x - 3), we get 6(x - 3) over x^2 - 10x + 21, which is the LCD.
Similarly, we get 5(x - 7) over x^2 - 10x + 21.
Now all three of the original fractions have the same denominator, x^2 - 10x + 21. We can now "drop" the LCD, which leaves us with:
x^2 - 29 = 6(x - 3) + 5(x - 7)
Performing the indicated multiplications, we get:
x^2 - 29 = 6x - 18 + 5x - 35. Combining like terms:
x^2 - 29 = 11x - 53, or x^2 - 11x + 24 = 0
This factors as follows: x^2 - 11x + 24 = 0 = (x - 3)(X - 8) = 0
Then the preliminary solutions are x = 3 and x = 8. Unfortunately, we cannot substitute x = 3 into the original equation, because that would lead to division by zero. The only valid solution is x = 8, since every term of the original equation is defined at x = 8, and the equation is true for this value.
Repeat: 3 cannot be a solution because the 3rd fraction is undefined at
x = 3. So we have only one valid solution (8) with no other solution to multiply by 8.
Answer: You may divide by a variable. But only if you know the variable is non-zero. So, if setting the variable to zero makes both sides of the equation zero, we have a solution that that variable is 0, or the equation with the variable divided out holds. E.g. solve x(x-1) = 0.

a diagram with line m parallel to line n is shown express the value of y in terms of x
Answer:
y = 170 - 3x
Step-by-step explanation:
l // m
y + 3x + 10 = 180 {co interior angles are supplementary}
y + 3x = 180 - 10 {Subtract 10 from both sides}
y+ 3x = 170 {Subtract 3x from both sides}
y = 170 - 3x

A buyer borrowed $85,000 to be repaid in monthly installments of $823.76 at 11.5% annual interest. How much of the buyer's first-month payment was applied to reducing the principal amount of the loan?
Answer: $9.18
Step-by-step explanation:
The payment of $823.76 will go towards both interest and principal repayments.
Find out the interest paid from the amount and deduct it from the monthly payment to find the principal repayment.
Monthly interest payment:
= (85,000 * 11.5%) / 12 months
= $814.58
Principal repayment = 823.76 - 814.58
= $9.18

A and C are equivalent.
6d+6=2(3d+3)
6d+6=3d+3+3d+3=(3d+3)+(3d+3)
Answer:
A and C
Step-by-step explanation:
Given
4d + 6 + 2d ← collect like terms
= 6d + 6
Comparing the following
A
2(3d + 3) ← distribute parenthesis by 2
= 6d + 6
B
6(d + 6) ← distribute parenthesis by 6
= 6d + 36 ≠ 6d + 6
C
(3d + 3) + (3d + 3) ← remove parenthesis
= 3d + 3 + 3d + 3 ← collect like terms
= 6d + 6
Thus A and C are equivalent to the original expression

The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?
an = 4 · ( ) n - 1
an = 2 · 4 n - 1
an = 32 · 2 n - 1
an = 4 · 2 n - 1
Answer:
a(n) = 4*(2)^(n - 1)
Step-by-step explanation:
The correct version of this formula is a(n) = a(1)*r^(n - 1). Must use the " ^ " symbol to indicate exponentiation, and enclose the "n - 1" inside parentheses.
Here, if 4, 8, 16, 32, ..., then a(1) = 4 and r = 2 (e. g., 16/8 = 2, 32/2 = 16, and so on).
Then the correct formula for this geometric sequence is
a(n) = 4*(2)^(n - 1), where use of the parentheses as indicated is mandatory.

a(n) = 4*(2)^(n - 1)

Work out m and c for the line: y=3x
Answer:
m = 3, c = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x , or y = 3x + 0 ← is in slope- intercept form
with m = 3 and c = 0
