The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot, where S is the speed in kilometers per hour and d is the average depth of the water in kilometers. A tsunami is traveling at 140 km/hr. What is the approximate average depth of the water? 0.133 km 0.145 km 0.155 km
Answer:
0.155 km
Step-by-step explanation:
Given the tsunami speed relation :
S = 356√d
Given a tsunami speed of 140/hr
s = 140km/hr
S = 356√d
Make d the subject
Divide both sides by 356
s / 356= √d
Hence,
140 / 356 = √d
0.3932584 = √d
Square both sides
0.3932584² = d
d = 0.1546 km
d = 0.155 km
Answer:
0.155 km

The radius of a cylindrical construction pipe is 3.5ft . If the pipe is 38ft long, what is its volume? Use the value 3.14 for (pie symbol) , and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer:
1462 cubic ft
Step-by-step explanation:
The volume of a cylinder can be found using the equation [tex]\pi r^{2}h[/tex]=V. The radius is 3.5 ft and the height is 38ft.
[tex](3.14)(3.5^{2})(38)[/tex]=V
(3.14)(12.25)(38)=V
1461.67=V and rounded to the nearest whole numbe, 1462 cubic ft=V

24 is 44% of what number?
yall i have exams tomorrow and i have no clue how to do percentages TwT helppp
Answer:
24 is 44% of 54.55
Step-by-step explanation:
24 ÷ 44% = y ÷ 100%
Solve for y - To do so, we will use cross multiplication.
44y = 24 × 100
44y = 2400
y = 2400 ÷ 100
y = 54.55
3. Given that ∆RSV - ∆RTU, find the coordinates of S and the scale factor. R(0, 0) T(16,0) V(0, --6) U(0, -8)
Answer:
I'll give the scale factor and you can compute the coordinates of S
Step-by-step explanation:
the dilation if centered about the origin is the scale factor multiplied by each coordinate.
so looking at points V and U, the scale factor F is found by solving for F:
-6xF= -8
F=8/6=4/3
Now you can compute the coordinates for S

Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent
Answer:
Please specify what the three expressions are.
Step-by-step explanation:
From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:
[tex]2(x-3)=2x-6[/tex]
Then, by evaluating it, you would get:
[tex]2x-6=2x-6[/tex] by distribution over subtraction.
[tex]2x-6+6=2x-6+6[/tex] by the additive property of equality
[tex]2x=2x[/tex] Simplify.
[tex]x=x[/tex] by the reflexive axiom.
Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.
Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.
Sorry I could not be of more help, but you did not specify what the expressions were.

Answer:
87,069.6 cm³
Step-by-step explanation:
V = (4/3)πr³
r = d/2 = 55 cm/2 = 27.5 cm
V = (4/3)(3.14)(27.5 cm)³
V = 87,069.6 cm³

Perimeter = 30 in.
Area = ?
Answer:
56
Step-by-step explanation:
the length of the missing side is 7
so 7 x 8 = 56
To find the missing side:
You must add 8 + 8 = 16
Subtract 16 from the total perimeter = 14.
Divide 14 by 2 = 7 you divide by two since there are two missing lengths and when you add them they have to equal to 14.

Write the polynomial in standard form. Then name the polynomial based on its degree and
number of terms.
6x² + 6x² – 2x²
O 6x2 – 2x – 2: second-degree
O 6x2 + 6x4 – 2x2, not a polynomial
O 6x4 Nx: fourth-degree binomial
6x4 + 4x2, fourth-degree binomial
Answer:
[tex]10x^2[/tex]
Second degree polynomial
Step-by-step explanation:
Given
[tex]6x^2 + 6x^2 -2x^2[/tex]
Solving (a): In standard form
[tex]6x^2 + 6x^2 -2x^2[/tex]
Solve
[tex]6x^2 + 6x^2 -2x^2 = 10x^2[/tex]
Hence, the standard form is: [tex]10x^2[/tex]
Solving (b): The name
The above has a single term and the power of x is 2,
Hence, it is a second degree polynomial
