Answer:
X = 12.21
Step-by-step explanation:
Since this is a right triangle, use the formula A^2 + B^2 = C^2 and plug in appropriate values.
(10)^2 + (7)^2 = C^2
100 + 49 = C^2
149 = C^2
12.2065 = C
Rounded to two decimal places, this makes X equal to 12.21.
The required value of x is 12.21 for the given right triangle.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
Since this is a right triangle, use the formula A² + B² = C² and substitute appropriate values.
(10)² + (7)² = x²
100 + 49 = x²
149 = x²
x = √149
x = 12.2066
Rounded to two decimal places,
x = 12.21
Therefore, the required value of x is 12.21.

Solve the system of linear equations below, using substitution method.
8x+9y=368x+9y=36
3x+4y=163x+4y=16
Answers
Given:
The system of equations is
[tex]8x+9y=36[/tex]
[tex]3x+4y=16[/tex]
To find:
The solution of the given system of equations using the substituting method.
Solution:
We have,
[tex]8x+9y=36[/tex] ...(i)
[tex]3x+4y=16[/tex] ...(ii)
From (ii), we get
[tex]3x=16-4y[/tex]
[tex]x=\dfrac{16-4y}{3}[/tex] ...(iii)
Putting this value in (i), we get
[tex]8\left(\dfrac{16-4y}{3}\right)+9y=36[/tex]
Multiply both sides by 3.
[tex]8(16-4y)+27y=108[/tex]
[tex]128-32y+27y=108[/tex]
[tex]-5y=108-128[/tex]
[tex]y=\dfrac{-20}{-5}[/tex]
[tex]y=4[/tex]
Putting y=4 in (iii), we get
[tex]x=\dfrac{16-4(4)}{3}[/tex]
[tex]x=\dfrac{16-16}{3}[/tex]
[tex]x=\dfrac{0}{3}[/tex]
[tex]x=0[/tex]
Therefore, the solution of given system of equations is (0,0).
Un objeto tiene una masa de 0.044Lb cuando se sumerge en una probeta que inicialmente contiene 0.350L de agua, el nivel de agua se eleva a 0.485L. ¿Cuál es la densidad (g/mL) del objeto?
Answers
Answer:
147.84 g/L
Step-by-step explanation:
Paso 1
El volumen del objeto se calcula como:
0.485L - 0.350L
= 0.135 litros
Paso 2
Convertimos la masa del objeto de libras a gramos
1 libra = 453.592 gramos
0.044 libras (lb) = x
Cruz multiplicar
x = 0.044 × 453.592 gramos
x = 19.958064 gramos
Paso 3
Densidad del objeto
= Masa (gramos) / Volumen (L)
= 19.958064 gramos / 0.135L
= 147.837511111 g / L
Aproximadamente = 147.84 g / L
Por lo tanto, la densidad (g / mL) del objeto es 147.84 g / L

Answers
Answer:
4
Step-by-step explanation:
The diagonals are equal length:
[tex]6x - 14 = 8x - 20\\-2x = -6\\x = 3[/tex]
[tex]BD = 6x - 14\\BD = 6 * 3 - 14\\BD = 18 - 14\\BD = 4[/tex]
The length of diagonal BD in rectangle ABCD is 4 units.
RectangleA rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal to each other. All the angles of a rectangle measure 90 degrees.
The diagonals of a rectangle are equal to each other.
AC = BD (diagonals of rectangle are equal)
6x - 14 = 8x - 20
2x = 6
x = 3
BD = 6(3) - 14 = 4 units
The length of diagonal BD in rectangle ABCD is 4 units.

Christi alters a skirt. She cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge. Which expression best represents the final length of the skirt?
Answers
Answer: ( x -2 ) inches
Step-by-step explanation:
Let x = length of skirt.
Given: Christi first cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge.
Cutting of length will be represented by a negative integer.
The expression best represents the final length of the skirt = x-7+5 inches
= x -2 inches
Hence, the expression best represents the final length of the skirt = ( x -2 ) inches

Answer:

Step-by-step explanation:
We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.
5x+6=16x-27
Continue to solve . . .
33 = 11x
x=3
Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get
(16 x 3) - 27, which is equal to 21°.
