Se sabe que los catetos de un triangulo rectangulo miden 0,4 cm y 0,3 cm. Micaela dice que su perimetro es igual a 1,2 cm ¿Sera cierto? De no ser asi , determina el valor del perimetro correcto
Answer:
El perímetro es de 1.2 cm
Step-by-step explanation:
La formula del perímetro de un triángulo rectángulo es:
p = cateto1 + cateto2 + hipotenusa
Para determinar el valor de la hipotenusa usamos el Teorema de Pitágoras:
hipotenusa² = cateto1² + cateto2²
hipotenusa² = 0.4² + 0.3²
hipotenusa² = 0.16 + 0.09
hipotenusa² = 0.25
√hipotenusa² = √0.25
hipotenusa = 0.5
entonces, el perímetro es:
p = 0.4 + 0.3 + 0.5
p = 1.2cm
por tanto
Micaela tiene razón, el perímetro es de:
1.2 cm

One number is 13 more than the product of 9 and another number. If the sum of the two numbers is 103, find the two numbers.
Answer:
x + y = 103 Subtract 2nd from 1st EQ
-10y = -90
y = 9 and x = 94 9%2A9%2B13
and...checking
sum = 103
Step-by-step explanation:
The two numbers are 9 and 94.
What are simultaneous equations?In mathematics, a set of simultaneous equation, also known as a system of equations or an equation system, is a set of equations for which common solutions are sought.
Let the two numbers be x and y.
Then according to question,One number is 13 more than the product of 9 and another number we have ,
13 + 9x = y
or,9x - y = -13...(i)
Also,the sum of the two numbers is 103. So we have,
x + y = 103 ...(ii)
Adding equation (i) and (ii) we get,
10x = 90
or, x = 9
Put the value of x in equation (ii), we get
9 + y = 103
or, y = 103 - 9
or, y = 94
Hence the two numbers are 9 and 94.

The sum of five consecutive integers is five. What is the product of the five integers?
The first integer = x
The second integer = x + 1
The third integer = x + 2
The fourth integer = x + 3
The fifth integer = x + 4
Since they all add up to 5, let's set them equal to 5
x + x + 1 + x + 2 + x + 3 + x + 4 = 5
Combine like terms
5x + 10 = 5
Subtract 10 from both sides
5x = -5
Divide each side by 5
x = -1
The first integer = x = -1
The second integer = x + 1 = -1 + 1 = 0
The third integer = x + 2 = -1 + 2 = 1
The fourth integer = x + 3 = -1 + 3 = 2
The fifth integer = x + 4 = -1 + 4 = 3
We can check this by adding all the integers together and making sure we get 5
3 + 2 + 1 + 0 - 1 = 5
Answer:
0
Step-by-step explanation:
If the sum of the integers is 5, then the arithmetic mean of the integers is [tex]$\frac{5}{5}=1$[/tex] . In five consecutive integers, the arithmetic mean is equal to the middle integer, which means the integers are -1, 0, 1, 2, 3 and the product is [tex]$\boxed{0}$[/tex].

Answer:
x = 56
Step-by-step explanation:
Step 1: Write out equation
x + 20 + x + 48 = 180
Step 2: Combine like terms (x)
2x + 20 + 48 = 180
Step 3: Combine like terms (constants)
2x + 68 = 180
Step 4: Subtract 68 on both sides
2x = 112
Step 5: Divide both sides by 2
x = 56

Find the distance between the two points. (round to the nearest hundredths)
distance:
Answer:
d = 5.10
Step-by-step explanation:
The distance between two points is given by
d = sqrt( ( y2-y1)^2 + ( x2-x1)^2 ) where ( x1,y1) and ( x2,y2) are the two points
d = sqrt( ( 5-6)^2 + (8-3)^2 )
d = sqrt( ( -1)^2 + (5)^2 )
d = sqrt( 1+25)
d = sqrt(26)
d = 5.099019514
Rounding to the nearest hundredth
d = 5.10
Answer:
[tex]d=\sqrt{26}\approx5.10[/tex]
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We can see that Point R is at (3,6), and Point E is at (8,5).
Let's let (3,6) be (x₁, y₁) and let's let (8,5) be (x₂, y₂). So, substituting them into our formula, we'll get:
[tex]d=\sqrt{(8-3)^2+(5-6)^2[/tex]
Subtract:
[tex]d=\sqrt{(5)^2+(-1)^2[/tex]
Square:
[tex]d=\sqrt{25+1}[/tex]
Add:
[tex]d=\sqrt{26}[/tex]
Approximate. Use a calculator:
[tex]d=\sqrt{26}\approx5.10[/tex]
So, the distance between RE is approximately 5.1 units.
And we're done!

Combine like terms fir the following expression: -3x+14-11+11x
Answer:
8x + 3
Step-by-step explanation:
In the expression -3x + 14 - 11 + 11x, we have two pairs of like terms that can be combined together:
-3x, 11x
14, -11
If we rewrite this expression with the like terms together, it would look like this:
-3x+11x + 14-11
To make the addition of -3x and 11x easier, we could switch their places in the expression to make it look like this:
11x-3x + 14-11
(Note: Even though we are switching the terms' places, the -3x still keeps its negative sign when you move it around.
11x-3x is 8x and 14-11 is 3.
Therefore, the expression -3x + 14 - 11 + 11x can be simplified by combining like terms into 8x + 3.
Convert this rate to feet per second. Round your answer to nearest tenth the average speed of a car on a stretch of the interstate is 70 miles per hour.
Answer:
102.66666667 feet/ seconds
Step-by-step explanation:
From the question, we are told to convert 70 miles per hour to feet per second.
Step 1
1 mile = 5280 feet
70 miles = x feet
Cross Multiply
1 mile × x feet = 5280 feet × 70 miles
x feet = 5280 feet × 70 miles
x feet = 369600 feet
Hence, 70 miles = 369600 feet
Step 2
We convert 369600 feet/ hour to feet per second
60 seconds = 1 minute
60 minutes = 1 hour
1 hour = 60 × 60
= 3600 seconds.
369600 feet/ 1 hour = 369600 feet/3600 seconds
= 102.66666667 feet/ seconds
Therefore, 70 miles per hour is equivalent to 102.66666667 feet/ seconds
