Answer:
Yes, this is a right triangle.
Step-by-step explanation:
The Pythagorean Theorem states that if the sum of the squares of the two small sides of a triangle add up to the square of the longest side, then the triangle is a right triangle: a² + b² = c², where a and b are the smallest sides (called legs) and c is the longest side (called the hypotenuse).
Here, the two smallest sides are 10 and 49.5, so let's square them, add them up, and see if they add up to 50.5²:
10² = 100
49.5² = 2450.25
100 + 2450.25 = 2550.25
50.5² = 2550.25
Since 10² + 49.5² equals 50.5², we know that this is a right triangle.
Thus, yes, this is a right triangle.

At a sandwich shop, they charge $2.75 for the basic sandwich and then $0.45 per ounce for the toppings. If
Willa paid for her sandwich with a $5 bill, how many ounces of toppings could she have ordered?
Answer: 3 toppings
Step-by-step explanation: If 2 topping equals $1 then its would come out to $3.75.$0 .75+$0.45= $1.20 the.n $3.75+ $1.20 = $4.95. That comes up to 3 toppings

The radius of a cylindrical water tank is 4 ft , and its height is 10 ft . What is the volume of the tank?
Use the value 3.14 for , π and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer:
2010 cu ft to the nearest whole number.
Step-by-step explanation:
Volume = π r^2 h
= 3.14 * 4^3 * 10
= 2009.6
The volume of the water tank is approximately 502 cubic feet.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
The volume V of a cylinder can be calculated using the formula V = πr²h, where r is the radius of the base and h is the height.
Substituting the given values, we get:
V = π (4 ft)² (10 ft)
V = 3.14 (16 ft²) (10 ft)
V = 502.4 ft³
Rounding this answer to the nearest whole number gives a final answer of V = 502 ft^3.
Therefore,
The volume of the water tank is approximately 502 cubic feet.

Answer: x = 12 degrees.
Step-by-step explanation:
The triangle ABC is a right triangle, which means that it has a right angle of 90 degrees.
This is represented by the small square on the bottom-left corner of the triangle.
The angle DBC is 78 degrees. There is also the angle of ABD, which is represented by X.
The right angle is equivalent to 78 degrees and x. You can represent this in an equation, where the sum of 78 degrees and x = 90 degrees, the right angle:
78 + x = 90
x = 12

Hello!
Answer:[tex]\boxed{ \bf The~area~of~the~shaded~region~is~B.~24 mm^2}[/tex]

Explanation:To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.
Outer:
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex](12 · 5)

Answer:
3.2 (and the equation is 3.4 + x = 6.6)
Step-by-step explanation:
the word problem is written as:
3.4 + x = 6.6
we want to solve for x.
to isolate x by itself, subtract 3.4 from both sides. (3.4 - 3.4=0 & 6.6 - 3.4 = 3.2)
now we have x = 3.2
so x equals 3.2

What is the y-value of the vertex of the function f(x)=-(x+8)(x-14)?
3
6
112
121
Answer:
121
Step-by-step explanation:
Given
f(x) = - (x + 8)(x - 14) ← expand factors using FOIL
= - (x² - 6x - 112) ← distribute by - 1
= - x² + 6x + 112
Given a quadratic in standard form. y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = - x² + 6x + 112 ← is in standard form
with a = - 1 and b = 6, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{6}{-2}[/tex] = 3
Substitute x = 3 into f(x) for corresponding value of y
f(3) = - (3)² + 6(3) + 112 = - 9 + 18 + 112 = 121
vertex = (3, 121 ) ← with y = 121

Step 2 :
Pulling out like terms :
2.1 Pull out c+2d
After pulling out, we are left with :
(c+2d) • ( (c+2d) +( (-1) * (3c-7d) ))
Answer:
(c+2d)(9d - 2c) = [tex]5dc - 2c^{2} + 18d^{2}[/tex]
Step-by-step explanation:
[tex](c+2d)^{2} - (c+2d)(3c-7d)[/tex]
[tex](c+2d)(c+2d) - (c+2d)(3c-7d)[/tex]
Both sides have (c+2d) so pull out (c+2d)
Rule: a.b + a.c = a(b+c)Rule: a.b - a.c = a(b-c)(c+2d) [(c+2d) - (3c-7d)]
(c+2d) [c+2d - 3c +7d]
(c+2d) [-2c + 9d] = (c+2d)(9d - 2c)
Rule: (a+b)( c + d) = ac + ad + bc + bd ==> Foil method(c+2d)(9d - 2c) = [tex]9dc - 2c^{2} + 18d^{2} -4dc[/tex] = [tex]5dc - 2c^{2} + 18d^{2}[/tex]

Answer:
A. Inside the circle
Step-by-step explanation:
K(0, 0), U (6, - 4), V ([tex] \sqrt 2,\: 7)[/tex]
In order to determine whether point V lie inside, outside or on the circle, first we will find the distances between points K & U and then K & V.
KU would be radius of the circle.
If KV is smaller than KU, then V will lie inside. If KV is larger than KU, then V will lie outside And If KV = KU, then V will lie ion the circle.[tex]d(KU) = \sqrt{ {(6 - 0)}^{2} + {( - 4 - 0)}^{2} } \\ = \sqrt{ {6}^{2} + {( - 4)}^{2} } \\ = \sqrt{36 + 16} \\ \red{ \bold{ d(KU)= \sqrt{52} }} \\ \\ d(KV) = \sqrt{ {( \sqrt{2} - 0)}^{2} + {( 7 - 0)}^{2} } \\ = \sqrt{ {( \sqrt{2)} }^{2} + {(7)}^{2} } \\ = \sqrt{2 + 49} \\ \purple{ \bold{ d(KV)= \sqrt{51} }} \\ \\ \because \: d(KU) > d(KV) \\ [/tex]
Hence point V lie inside of the circle.

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. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Given data ,
Let the equation be f ( x )
The equation f ( x ) is x² - 10 = 26
Now , adding 10 on both sides , we get
x² = 36
Taking square roots on both sides , we get
x = ±6
We know , (-6)² = 36 and (+6)² = 36
Therefore , x can have 2 solutions , which is ±6
Hence , the two values which x can have will be +6 and -6
