Answer:
The hypotenuse is sqrt ( 2x^2)
Step-by-step explanation:
Given a right angled triangle, we can find the hypotenuse of a triangle using the Pythagorean theorem which says that c^2 = a^2 + b^2, where a is the length, b is the perpendicular height and c is the hypotenuse. The length of the triangle (l) is x and the height of the triangle is also x. By substituting the values,
c^2 = x^2 + x^2 = 2x^ 2
There are two possible answers to c but the hypotenuse cannot be negative.
Hence,
c = Sqrt (2x^2)

Verify a ÷ b ≠ b ÷ a , if a = −3/4 and b = 4/5
Given:
[tex]a=-\dfrac{3}{4}[/tex]
[tex]b=\dfrac{4}{5}[/tex]
To verify:
[tex]a\div b\neq b\div a[/tex]
Solution:
We have,
[tex]a=-\dfrac{3}{4}[/tex]
[tex]b=\dfrac{4}{5}[/tex]
Now,
[tex]a\div b=\dfrac{a}{b}[/tex]
[tex]a\div b=\dfrac{-\dfrac{3}{4}}{\dfrac{4}{5}}[/tex]
[tex]a\div b=-\dfrac{3}{4}\times \dfrac{5}{4}[/tex]
[tex]a\div b=-\dfrac{15}{16}[/tex] ...(i)
And,
[tex]b\div a=\dfrac{b}{a}[/tex]
[tex]b\div a=\dfrac{\dfrac{4}{5}}{-\dfrac{3}{4}}[/tex]
[tex]b\div a=\dfrac{4}{5}\times (-\dfrac{4}{3})[/tex]
[tex]b\div a=-\dfrac{16}{15}[/tex] ...(ii)
From (i) and (ii), it is clear that
[tex]a\div b\neq b\div a[/tex]
Hence verified.

2x - x + 9 + 3x - 2 = 16
O A - 23
B. x - 3
O O O o
c. x-?
D. . -
Answer:
the answer is b
Step-by-step explanation:
Answer:
x = 9/4
Step-by-step explanation:
2x - x + 9 + 3x - 2 = 16
Combine like terms
4x + 7 = 16
Subtract 7 from both sides
4x = 9
Divide both sides by 4
x = 9/4
x(x+2) + y (x + 2) - 5(x + 2)
factor
Answer:
x² + xy - 3x + 2y - 10
Step-by-step explanation:
x(x + 2) + y(x + 2) - 5(x + 2)
x² + 2x + y(x + 2) - 5(x + 2)
x² + 2x + xy + 2y - 5(x + 2)
x² + 2x + xy + 2y - 5x - 10
x² - 3x + xy + 2y - 10
x² + xy - 3x + 2y - 10

Consider the algebraic expression:
−z − 7y + 18x + 4
Which of the following is a constant in this expression?
Which of the following lists all the coefficients in this expression?
Answer:
constant: 4
coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)
Step-by-step explanation:
coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.
constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
therefore, 4 is a constant.
hope this helps! if it does, please mark brainliest! thanks!

Step-by-step explanation:
Leo is buying milk for his family for a week. He said he bought 7 kilograms of milk. Is his answer reasonable? Explain.
Answer:
First, we know that a single liter of milk weighs around 1.032 kg.
Then 7 kilograms of milk is equivalent to (almost) 7 liters of milk.
Now, this is reasonable?
Well, for a typical person, the consumption is between 0.5L and 0.75L
So 7kg of milk may less of what a typical family consumes in a week, but is not an outlier (for example, 30kg of milk or 1kg of milk per week are outliers, which are "nonreasonable") so 7 kg is a reasonable amount of milk.
Now, if the question only refers to the units he used (kg instead of liters) this does not matter, as we know, mass and volume are two different, but equivalent, ways of describing a known matter, as these are related by the density:
Density = mass/volume.
So, for a known material, if you know the mass that you have, you also know the volume.
Then using kg is reasonable in this situation.
If f(x) = x2 + 1 and g(x) = x – 4, which value is equivalent to (f circle g) (10)?
37
97
101
132
Answer:
A
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=x^2+1\text{ and } g(x)=x-4[/tex]
And we want to find:
[tex](f\circ g)(10)[/tex]
This is equivalent to:
[tex]=f(g(10))[/tex]
Find g(10) first:
[tex]g(10)=(10)-4=6[/tex]
Substitute:
[tex]f(g(10))=f(6)[/tex]
Evaluate f(6):
[tex]f(6)=(6)^2+1=37[/tex]
Therefore:
[tex](f\circ g)(10)=37[/tex]
Our answer is A.

A bag contains 9 identical balls out of which 3 are blue, 2 are white and the remaining are red.
If a ball is drawn from the bag what is probability that it is :
1. blue
2.not red.
Answer:
Total number of balls = 9
P(blue) = blue / total = 3/9 = 1/3 or 33.33%P(not red) = (total - red)/total = 5/9 or 55.55%!!!NO LINKS!!! NEED HELP DUE NOW!!!

Answer:
PK = 75
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{PK}{WK}[/tex] = [tex]\frac{AK}{NK}[/tex] , substitute values
[tex]\frac{PK}{54}[/tex] = [tex]\frac{62.5}{45}[/tex] ( cross- multiply )
45 PK = 3375 ( divide both sides by 45 )
PK = 75
write an equation then find the angle measure for A. 25 points and brainliest.
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4 + 3x + 3x + 14 + 90 = 180 , simplify left side
108 + 6x = 180 ( subtract 108 from both sides )
6x = 72 ( divide both sides by 6 )
x = 12
Then
∠ A = 4 + 3x = 4 + 3(12) = 4 + 36 = 40° → A
3 -4. Litros d jugo de frutilla 1 y 1-2 litro de jugo de manzana 1-8 litro de jugo de limón Y 1 y 1-2 litro de agua .Cuántos litros de jugo preparo la mamá??
Answer:
La madre hizo en total 2 y 3/8 litros de jugo.
Step-by-step explanation:
Sabemos que preparó:
3/4 litros de jugo de frutilla = 3/4 L
1 y 1/2 litro de jugo de manzana = (1 + 1/2) L
1/8 litro de jugo de limón = 1/8 L
1 y 1/2 litro de agua = (1 + 1/2) L
¿Cuántos litros de jugo preparó la mamá?
Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)
Total de jugo = 3/4 L + (1 + 1/2) L + 1/8 L
Para completar esta suma, separamos los números enteros de los racionales:
Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L
Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.
Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.
Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:
Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L
= 1 L + (6/8 + 4/8 + 1/8) L
= 1 L + (11/8) L
podemos reescribir el segundo termino como:
= 1L + (8 + 3)/8 L
= 1L + (8/8) L + (3/8) L
= 1L + 1L + 3/8 L
= 2L + 3/8 L
La madre hizo en total 2 y 3/8 litros de jugo.

En una camioneta se pueden transportar 28.5 kilogramos. ¿ Cuántas camionetas se necesitan para transportar 484.5 Kg?
Answer:
The number of trucks required is 17.
Step-by-step explanation:
28.5 kilograms can be transported in a van. How many trucks are needed to transport 484.5 Kg?
For the transportation of 28.5 kg, one truck is required.
Total mass = 484.5 kg
The number of trucks required is
n = total mass/ mass of one

Find the total area by breaking the figure into two rectangles, one trapezoid, and one triangle.
Rectangles:
A = l × w
A = 2.75 × 4 = 11 in²
Solve for the other rectangle's length by subtracting from the total:
12 - 2 - 3 - 4 = 3
A = 3 × 3 = 9 in²
Total rectangle area: 11 + 9 = 20 in²
Trapezoid:
A = 1/2(b1 + b2)h
A = 1/2(4.25 + 2.75)3 = 21/2 = 10.5 in²
Triangle:
A = 1/2(bh)
A = 1/2(2.5 · 2) = 2.5 in²
Add up all of the areas:
20 + 10.5 + 2.5 = 33 in²
