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:
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.

In an equilateral triangle, all the angles measure 60 degrees. Knowing this, we can set the following equations:
[tex]60=y-10\\60=x+5[/tex]
[tex]60=y-10[/tex]
Add 10 to both sides
[tex]60+10=y-10+10\\70=y[/tex]

Answer:
x is 55° & y is 70°.
Step-by-step explanation:
This is an equilateral triangle.
In an equilateral triangle all sides are 60°
So,
1) x+5 = 60
x = 55°.
2) y-10 = 60
y = 70°.
Answer: x is 55° & y is 70°.
Find m<YQR pls need grade gud.
Answers
Answer:
21°
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°.

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

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]

Answer:

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.
