Answer:
417
Step-by-step explanation:
count 1, 3, 5, (7) is the fourth one
it needs to be rounded to 400 so it is between 350 and 450
lets try in the 300s, 12 -(3 + 7) = 2. but 327 does not round to 400 so it does not work
lets try in the 400s, 12 - (4 + 7) = 1. put that one in the middle and you get 417 which fits the entire description
Answer:
Cannot be determined since the question is wrong.
Step-by-step explanation:
The fourth odd number is: 1, 3, 5, 7
h+t+o=12
h+t+7=12
Subtract 7 from both sides
h+t=5
If it rounds up to 400, h must be 3.
3+t=5
Subtract 3 from both sides
t=2
So our number is 327? It doesn't round up to 400 so the question is probably wrong. You probably got a typo in their like the numbers adding up to 12 or rounding to 300.

A. David notices that the shape of the Ligersville toxic dump site is somewhat like a triangle. He claims that he can approximate the perimeter of the dump site without doing any extra measurements. What assumption about side AB of the dump site would David need to make in order to justify his claim?
B. Based on the assumption in part A, determine the approximate length of side AB of the dump site. Explain your reasoning in at least two sentences.
C. Determine the approximate perimeter of the Ligersville toxic dump site. Explain your reasoning.
Answers and Step-by-step explanations:
A. David would need to assume that side AB is the hypotenuse of the almost-right triangle that A, B, and C make. That way, he can use the Pythagorean Theorem to solve for AB.
B. AB² = 24² + 32² = 1600 ⇒ AB = √1600 = 40 yards
We can use the Pythagorean Theorem because we assume that ABC is in the form of a right triangle, with AB as the hypotenuse. Then since whenever we have a right triangle, we can use the Pythagorean Theorem to solve for an unknown side, that applies here as well.
C. The approximate perimeter is 24 + 32 + 40 = 96 yards. Using the approximation of AB from part B, we simply add up all the side lengths of this "triangle", as that is the definition of "perimeter". Thus, when we add them all together, we get a total of 96 yards.
Answer:
A. Assumption: length of the curve AB is equal to the hypotenuse of the triangle formed AB was a straight line.
B. 40 yards
C. 96 yards
Step-by-step explanation:
A. Assumption: length of the curve AB is equal to the hypotenuse of the triangle formed AB was a straight line.
B. AB² = 32² + 24²
AB² = 1600
AB = 40
Since we have assumed that AB is equal to the hypotenuse, we can use pythagoras theorem to find an approximate length of AB
C. Perimeter is the sum of all lengths:
32 + 24 + 40 = 96
Line AB is tangent to circle O at B. Find the length of the radius r for AB = 8 and AO = 11.7. Round to the nearest tenth if necessary. The diagram is not to scale.13.7, 3.7, 8.5, 14.2
Answer:
8.5
Step-by-step explanation:
So the line segment that is tangent to the circle is 8, and AO is 11.7.
When you connect them, they are perpendicular, so you have a right triangle with one unknown leg that we will call X, a leg that is 8, and a hypotenuse that is 11.7.
If you use the Pythagorean Theorem, you will find that the leg is √72.89, which is approximately 8.5.
That leg is the radius.

Step-by-step explanation:
Una catedral esta situada en la cima de una colina. Cuando la punta de su torre se observa desde el ple de la loma, el angulo de elevacion es de 48°. Cuando se ve desde un punto a una distancia de 6096 m del pie del promontorio, el angulo de elevacion es de 41° la cuesta de la colina forma un angulo de 32° Aproxima la altura de la catedral
Answer:
La altura de la catedral es de 15119,97 m.
Step-by-step explanation:
Para una respuesta única, la pregunta se formula de la siguiente manera:
Una catedral se encuentra en la cima de una colina. Cuando se ve la parte superior de su torre desde la parte inferior de la colina, el ángulo de elevación es de 48 °. Cuando se ve desde un punto a 6096 m del pie del promontorio, el ángulo de elevación es de 41 °, la pendiente de la colina forma un ángulo de 32 ° Se aproxima a la altura de la catedral
Deje que la base de la colina = C
El punto 6096 m de la base = A
La cima de la catedral = B
∴ ∠A = 41 °
∠C = 180-48 = 132 °
∠B = 180 - (41 + 132) = 7 °
[tex]\dfrac{6096}{sin7} = \dfrac{CB}{sin41}[/tex]
∴ CB = 32816.59 m.
Punto E = Base de la catedral.
Punto D = Punto debajo de la base de la catedral al nivel del pie de la colina
Por lo tanto, la altura de la catedral = BE
∡ABE = 90-41 = 49 °
∡CED = 90-32 = 58 °
∴ ∡CEB = 180 - 58 ° = 122 °
De la regla seno tenemos;
[tex]\dfrac{CB}{sin(\angle CEB)} = \dfrac{BE}{sin(\angle ECB)}[/tex]
∠EBA = 90 - 48 = 42°
∠EBC = 42 - 7 = 35°
∠ECB = 180 - 35 - 122 = 23°
[tex]\therefore \dfrac{32816.59 }{sin(122)} = \dfrac{BE}{sin(23)}[/tex]
[tex]BE = \dfrac{32816.59 }{sin(122)} \times sin(23) = 15119.97 \ m[/tex]
La altura de la catedral = 15119,97 m.

Find the length of the third side to the nearest tenth.
Answer:
5.3
Step-by-step explanation:
You use the Pythagoras theorem which is a^2+b^2=c^2.
Since you're solving for a side length that's not the hypotenuse you will manipulate the equation to c^2-a^2=b^2. From here you just plug in numbers.
8^2 - 6^2 = b^2
64 - 36 = b^2
b = sqrt(28)
b = 5.2915.... = 5.3

If using the method of completing the square to solve the quadratic equation x^2+15x+25=0x
2
+15x+25=0, which number would have to be added to "complete the square"?
Answer:
x = -15/2 ± (1/2)*5√5
Step-by-step explanation:
I will assume that you meant x^2+15x+25=0.
To complete the square, take half of the coefficient of x, square the result, add this square into the equation after '15x,' and then subtract the square from the result:
x^2+15x+25=0 => x^2 + 15x + (15/2)^2 - (15/2)^2 + 25 = 0.
Rewrite the first two terms as (x + 15/2)^2 - 225/4 + 100/4 = 0, or
(x + 15/2)^2 - 125/4 = 0
Taking the square root of both sides, we obtain the solutions:
x + 15/2 ±√[125/4], or
x = -15/2 ± (1/2)*5√5
The quadratic equation x²+15x+25=0, (15/2)² is a number to be added to "complete the square"
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The quadratic equation x²+15x+25=0
x²+15x+(15/2)²+25-(15/2)²=0
(x+15/2)²+25-225/4
(x+15/2)²+(100-225)/4
(x+15/2)²+(-125/4)
(x+15/2)²-(√125/√4)²
(x+15/2+√125/√4)(x+15/2-√125/√4)
(x+15/2+√125/2)(x-15/2-√125/2)
(x+(15+√125)/2)(x-(15+√125)/2)
Hence (15/2)² is a number to be added to "complete the square"

What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
From the given graph, the coordinate points are (1, 8) and (0, 2)
Using the formula [tex]y=a\times(b)^x[/tex]
Where, a is x-intercept
Substitute, a=2 and (x, y)=(1, 8) in [tex]y=a\times(b)^x[/tex], we get

(8,15,17)
(9,40,41)

A trucking company needs to move a pile of dirt. The dirt is stored in a pile shaped like a cone. The pile is 12 yards high, and its base has a diameter of 8 yards. How many truckloads will the company need, if each truck holds 6.28yd3 of dirt?
Answer:
it will take 96 truckload trips to move the entire pile of dirt.
Step-by-step explanation:
The formula for the volume of a cone of height h and radius r is
V = πr²h. Here, the radius, r, is half the given diameter, or r = d/2, or r = (8 yds)/2, or 4 yds, and the height is 12 yds. Thus, in this case, the volume of the conical pile of dirt is
V = π(4 yd)²·12 yd, or
V = 3.14(16 yd²)(12 yd), or
V = 602.88 yd³
If each truck holds 6.28 yd³ and we want to know how many truckloads the company needs in order to move the conical pile, we divide the above volume (V) by 6.28 yd³:
V 602.88 yd³
------------- = --------------------------------------- = 96
6.28 yd³ (6.28 yd³ per truckload)
We interpret this to mean that it will take 96 truckload trips to move the entire pile of dirt.
The number of truckloads the company will need is A = 32 truckloads
What is a Cone?A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.
The volume of a cone is given by the equation
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
Surface area of the cone = πr ( l + r )
where l = √ ( b² + r² )
Given data ,
The first step is to find the volume of the pile of dirt using the formula for the volume of a cone: V = ( 1/3 ) πr²h, where r is the radius of the base and h is the height.
The height of the cone is given as 12 yards, and the diameter of the base is 8 yards, so the radius is half of that, or 4 yards. Plugging in these values, we get:
V = (1/3)π (4 yards)² (12 yards)
V ≈ 201.06 yards³
Next, we need to find out how many truckloads the company will need.
We know that each truck can hold 6.28 cubic yards of dirt, so we can divide the total volume of dirt by the volume of one truckload to find the number of truckloads needed:
201.06 cubic yards / 6.28 cubic yards/truckload ≈ 31.99 truckloads
Since the company can't order a fractional number of truckloads, they will need to round up to the nearest whole number.
Hence , the company will need 32 truckloads to move the pile of dirt

Answer: 15cm.
Step-by-step explanation:
Hi, to answer this question we have to multiply the real height of the kite (1.5m) by the scale factor of the drawing (10):
Mathematically speaking:
Since 1 m = 10 cm
So:
1.5 m x 10 cm/m = 15 cm
The kite is 15 centimeters tall in the drawing.

Answer:
9 packages
Step-by-step explanation:
Each package will have 6 sheets, so to find the number of packages for 55 sheets, we can just use a rule of three:
1 package -> 6 sheets
x packages -> 55 sheets
x * 6 = 55 * 1
x = 55 / 6 = 9.17
Rounding down, we have x = 9 packages.
So it can be done a total of 9 packages, and there will be (55 - 9*6) = 1 sheet left.
