Jesus tiene un terreno cuadrado y su hermano uno rectángulalar,El Largo Del Terreno De Su hermano mide 5 metros más que el lado que el terreno que Jesús.mientras que el ancho del terreno de Si hermano mide lo mismo que el ancho del terreno cuadrado. ¿Cual es el area total de los terrenos?
Answer:
El terreno de Jesus es cuadrado.
El terreno del hermano es rectangular.
Definimos las variables:
Lh = Largo del terreno del hermano.
Ah = Ancho del terreno del hermano
Lj = Largo del terreno de Jesus.
Sabemos que:
Lh = 5m + Lj
Ah = Lj.
Sabemos que el area de un quadrado de lado L es igual a L^2.
Entonces el area del terreno de Jesus es Lj^2.
El area de un rectangulo de largo L y ancho A es igual a A*L.
El area del terreno del hermano de Jesus es:
Lh*Ah = (5m + Lj)*Lj
= 5m*Lj + Lj^2.

Let the ages be r and m
We have:
r + m = 1175r = 9 + 3mSubstitute m in the second equation and solve for r:
m = 117 - r5r = 9 + 3( 117 - r)5r = 9 + 351 - 3r5r + 3r = 3608r = 360r = 360/8r = 45Then m is

if a normal dice is rolled 900 times how many times is the number 4 expected
Answer:
125 times
Step-by-step explanation:
Here, we are required to determine how many times is the number 4 expected if a normal dice is rolled 900 times.
The number of times the number 4 is expected when a normal dice is rolled 900 times is; 900(1/6) = 150times.For a normal dice, there are six faces labelled numbers; 1, 2, 3, 4, 5, 6.
The probability of obtaining the number 4 each time the die is rolled is; 1/6
At the first roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the first roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the second roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the first roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the second roll of the normal dice, the probability of obtaining the number 4 is 1/6.At the third roll of the normal dice, the probability of obtaining the number 4 is 1/6.The probability of obtaining 4 in all 3 rolls is;
(1/6 + 1/6 + 1/6) = 3(1/6).
Ultimately, the number of times the number 4 is expected when a normal dice is rolled 900 times is; 900(1/6) = 150times.

What are the coordinates of the vertices of a dilation for triangle ABC at A (-1,-1) B(4,0) and C(2,3). A'B'C'
with scale factor 2.5 centered at the origin?
Answer:
The coordinates of the image of Δ ABC are:
A' (-2.5, -2.5), B' (10, 0), C' (5, 7.5)
Step-by-step explanation:
Let us revise the rule of dilation
If the point (x, y) dilated by scale factor k centered at the origin, then the image of the point is (k x, k y)
We will use this rule to solve the question
∵ The vertices of triangle ABC are A (-1, -1), B (4, 0), C (2, 3)
∵ The scale factor of a dilation is 2.5
∴ k = 2.5
∵ The center is the origin
→ That means multiply each coordinate of the points by 2.5
∴ A' = (-1 × 2.5, -1 × 2.5)
∴ A' = (-2.5, -2.5)
∴ B' = (4 × 2.5, 0 × 2.5)
∴ B' = (10, 0)
∴ C' = (2 × 2.5, 3 × 2.5)
∴ C' = (5, 7.5)
The coordinates of the image of Δ ABC are:
A' (-2.5, -2.5), B' (10, 0), C' (5, 7.5)

Given the function f(x) = -0.5|2x + 2| + 1, for what
values of x is f(x) = 6?
Answer:
No values of x can make f(x)=6
Step-by-step explanation:
Equation with Absolute Value
The absolute value of a number is always positive. That condition must be met when solving equations. Any condition that goes against the rule, must be discarded and not part of the solution.
The function provided in the question is:
[tex]f(x) = -0.5|2x + 2| + 1[/tex]
We need to find the value(s) of x that make:
f(x)=6
It needs to solve the equation:
[tex]-0.5|2x + 2| + 1=6[/tex]
Subtracting 1:
[tex]-0.5|2x + 2| =6-1=5[/tex]
Dividing by -0.5:
[tex]|2x + 2| =5/(-0.5)=-10[/tex]
We reach to this equation to solve:
[tex]|2x + 2| =-10[/tex]
As stated above, the absolute value is always positive, and the equation forces the absolute value to be negative. There is no possible value of x that makes the absolute value negative, thus:
No values of x can make f(x)=6
Answer:
No Solution

What is binomial theorem?
" Binomial theorem is a way of expanding a binomial expression with exponent n, where n is any positive integer."
Formula used
Binomial Expansion
(a - b) ⁿ = ⁿC₀ aⁿb⁰+ ⁿC₁ aⁿ⁻¹ (-b)¹ + ⁿC₂ aⁿ⁻² + ....... + (-1)ⁿ ⁿCₙ a° bⁿ
According to the question,
Given,
(4 -2z)³
a = 4
b = 2z
Substitute the value in the formula of binomial expansion we have,
= ³C₀ (4)³ (-2z)⁰ +³C₁ (4)² (-2z)¹ +³C₂ (4)¹ (-2z)² + ³C₃ (4)⁰ (-2z)³
= (4)³ - 3 (4)² (2z) + 3 (4) (2z)² -(2z)³
= 64 -96z +48z² -8z³
Hence, expansion of ( 4- 2z)³ using binomial expansion is equals to

Select all the statements that must be true for any scaled copy Q of Polygon P. Angle measures of Polygon P clockwise from bottom left, in degrees, 90, 125, 35, 250, 80, 135. Group of answer choices The side lengths are all whole numbers. The angle measures are all whole numbers. Q has exactly 1 right angle. If the scale factor between P and Q is LaTeX: \frac15 1 5 1 5 1 5 , then each side length of P is multiplied by LaTeX: \frac15 1 5 1 5 1 5 to get the corresponding side length of Q.
Answer:
The correct options are;
1) The angle measures are all whole numbers
2) Q has exactly 1 right angle
Step-by-step explanation:
1) When a polygon is scaled to obtain another polygon, whereby the scale factor for the transformation is constant, we have;
The ratio of the sides of the two polygon will be constant, and the two polygons will be similar
Therefore, the interior angles of the polygon and the scaled copy will be equal
Given that the interior angles of the original polygon are all whole numbers, and the interior angles of the scaled copy are congruent to the interior angles of the original polygon, the interior angles of the scaled of the scaled copy are therefore all whole numbers.
2) Similarly, given that the interior angles of the original polygon has exactly 1 right angle, the interior angles of the scaled copy will therefore have exactly 1 right angle.

Answer: $25.41
Convert the percentage into a decimal, and then multiply that decimal by the total price to find the tip. Subtract the tip amount from the total price to find the price before the tip.
15 ÷ 100 = 0.15
15% of 29.90 = 0.15 · 29.90 = 4.48500 ≅ $4.49
$29.90 - $4.49 = $25.41
∴ the price before tip, b, of Mr. Johnson's lunch is $25.41.
7(6+d)=49 Solve for d.
A:d=7
B:d=-1
C:d=-7
D:d=1
Answer: d = 1
Step-by-step explanation:
First distribute the 7 to each term of (6 + d) = 42 + 7d = 49 now subtract 42 from both sides which = 7d = 7. Divide by 7 = 7d/7 = 7/7 = d = 1
