Step-by-step explanation:
Solve the equation by completing the square. If necessary, round to the nearest hundredth. x2+10x=18
To solve the quadratic equation x² + 10x = 18 by completing the square, we rearrange the equation, complete the square, solve for x by taking the square root of both sides, and then isolate x. The two solutions are x = -5 + √43 and x = -5 - √43, which can be approximated if necessary.
To solve the equation x² + 10x = 18 by completing the square, we first need to move all terms to one side to get the equation in the form of ax² + bx + c = 0.
Subtracting 18 from both sides, we have x² + 10x - 18 = 0.
To complete the square, we take the coefficient of x, which is 10, divide it by 2 to get 5, and then square it to get 25. We add 25 to both sides of the equation and then subtract it right back to maintain the balance:
x² + 10x + 25 - 25 - 18 = 0
Now we group the perfect square trinomial and simplify:
(x + 5)² - 43 = 0
Next, we add 43 to both sides:
(x + 5)² = 43
Then we take the square root of both sides:
(x + 5) = √43
Subtract 5 from both sides to solve for x:
x = -5 ± √43
The solutions are x = -5 + √43 and x = -5 - √43.

= (1/3) x pi x radius^2 x height
= (1/3) x pi x 2^2 x 4
= 16.76 (mi3)
Option D is correct
Hope this helps!
:)
Answer:
16.76
Step-by-step explanation:
Volume= πr^2 h/3
so its π (2)^2 4/3
which equals 16.76 mi^3

The system of equations shown below is graphed on a coordinate grid:
3y + x = 4
2y − x = 6
Which statement is true about the coordinates of the point that is the solution to the system of equations?
It is (−2, 2) and lies on both lines.
It is (−5, 3) and lies on both lines.
It is (−5, 3) and does not lie on either line.
It is (−2, 2) and does not lie on either line.
Answer:
A) (-2,2) lies on both lines
Step-by-step explanation:
Your answer would be the first option, (-2, 2).
We can solve this system of equations by adding them together, as the +x and -x will cancel:
3y + x = 4
+2y - x = 6
5y = 10
y = 2
Now we can find the x value by substituting the y value into one of the equations:
3(2) + x = 4
6 + x = 4
x = -2
Therefore your answer is (-2, 2). We know that it is the first option and not the last option because the point (-2, 2) does lie on both lines as it satisfies both equations when substituted in.

If P(not yellow) = StartFraction 4 over 15 EndFraction, which best describes the probability of the complement of the event?
Answer:
The P(yellow) = 11/15
Step-by-step explanation:
Here, we have;
P(not yellow) = 4/15
Mathematically, the addition of the probability of an event and its complement adds up to be 1
The complement we have here is P(yellow)
Thus, mathematically we have;
P(not yellow) + P(yellow) = 1
P(yellow) = 1 - P(not yellow)
From the question P(not yellow) = 4/15
Plugging this value, we have;
P(yellow) = 1 - 4/15 = 11/15
Answer:
C. 11/15

If a car can drive 62 miles on 3 gallons of gas, how many gallons of gas will it use to travel 231 miles?
Answer:
11 gallons of gas is needed to travel 231 miles.
Step-by-step explanation:
We can set up a proportion for this problem.
For every 62 miles, you use 3 gallons of gas.
[tex]\frac{62}{3}*\frac{231}{?}[/tex]
Now, let's cross multiply.
[tex]\frac{693}{62}[/tex] ≈ [tex]11[/tex]
So, you will need about 11 gallons of gas to travel 231 miles.

The two right triangular prisms are congruent. What is the area of their bases?
15 in.
V = 90 in.
The two cylinders are congruent What is the height of cylinder B?
Step-by-step explanation:
3. The prisms are congruent, so they have the same base, height, and volume.
Volume of a prism is:
V = Ah
Plugging in values and solving for A:
90 in³ = A (15 in)
A = 6 in²
4. The cylinders are congruent, so they have the same radius, height, and volume.
Volume of a cylinder is:
V = πr²h
Plugging in values and solving for h:
176π cm³ = π (4 cm)² h
h = 11 cm
If y - 12 = 23, what would you do to solve for x? *
option 1 - add the 12 to both sides
option 2 - subtract the 12 from both sides
option 3 - subtract 23
Answer:
Option 1 - add the 12 to both sides.
Step-by-step explanation:
If you meant solve for the variable, y, then you should:
Option 1 - add the 12 to both sides.
y - 12 = 23
Isolate the variable, y. Add 12 to both sides:
y - 12 (+12) = 23 (+12)
y = 23 + 12
Simplify:
y = 23 + 12
y = 35

The top of a ladder rest at a height of 15 feet against the side of a house. If the base of a ladder is 6 ft from the house what is the length of the ladder? round to the nearest foot.
Answer:
16 feet
Step-by-step explanation:
We use Pythagorean Theorem to find the height.
leg of triangle= height of ladder = 15 feet
The hypotenuse of the formed triangle = length of ladder = L
base = 6 feet
What is length of ladder?
L^2 = 15^2 + 6^2 = 225 + 36 = 261
L = root(261) = 16.155 feet
Which equations explain why Mya's claim must be true?
Answer:
(4) (M∠1 + m∠2) = 180 and (m∠3 + m∠4 + m∠2) = 180
Step-by-step explanation:
The correct equation which represent Mya's claim must be true is,
⇒ m ∠1 + m ∠2 = 180°
And, m ∠3 + m ∠4 + m ∠2 = 180°
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degree.
Given that;
Mya claims that,
⇒ m ∠3 + m ∠4 = m ∠1
We know that;
Sum of all interior angles in triangle are 180 degree.
And, Sum of opposite angles of a triangle is equal to its exterior angle.
Hence, We get;
The correct equation which represent Mya's claim must be true is,
⇒ m ∠1 + m ∠2 = 180°
And, m ∠3 + m ∠4 + m ∠2 = 180°

The caribou’s spring migration takes 2 weeks. The longest recorded migration was 838 miles. How far did the caribou travel per day?
Answer:
59.85714285714286 miles a day ≈ 60 miles a day
Step-by-step explanation:
To find this, we'd have to make the weeks into days.
2 weeks * 7 days = 14 days
Now we need to divide the miles traveled by the days:
838/14=59.85714285714286 miles a day or about 60 miles per day
Answer:
~ 60 days
Step-by-step explanation:
We have 2 weeks. Since there are 7 days a week, 2 weeks is 14 days.
To find the number of miles walked per day, we need to divide the total number of miles by the total number of days:
838 / 14 ≈ 59.9 ≈ 60 days
