Answer:
[tex]2x^2+x+7y[/tex]
Step-by-step explanation:
We are given the equation [tex]2(x^2+3y)+x+y[/tex] and are asked to simplify it.
To do so, we need to first get rid of the parenthesis, since x² and 3y aren't like terms, it isn't solvable unless we try another way, which is the distributive property.
2 is next to the parenthesis, in the distributive property, we would multiply the number outside of the parenthesis with all the numbers inside the parenthesis. Therefore :
[tex](2*x^2) + (2*3y) + x +y[/tex]
[tex]2x^2 +6y+x+y[/tex]
Now that we have like terms, we can add them together :
[tex]2x^2 + 6y+x+y[/tex]
[tex]2x^2 + x+7y[/tex]
Answer:
Hello! Your answer would be, 2[tex]x^{2}[/tex] + [tex]x[/tex] [tex]7y[/tex]

Explain how you will evaluate 4[ 3(62+1)] - 63
Answers
Answer:
693
Step-by-step explanation:
You can simply apply BODMAS(Bracket of Division Multiplication Addition Subtraction)
Here, the brackets come first
62+1=63
63*3=189
189*4=756
756-63=693
Answer:
720
Step-by-step explanation:
First you do the things inside the parenthesis which is 62 + 1 = 63
Which gives you this -----> 4[ 3 x 63]-36
Then do the brackets (brackets are these btw "[ ]" )
After doing the brackets you should bet this 4 x 189 - 36
Then you do the multiplication -----> 756 - 36
756 - 36 = 720

As shown, several colored paper squares are placed in a bowl. One paper square is randomly selected. Is this a uniform or non-uniform probability model? Justify your reasoning. A) It is a uniform probability model because each color has an equal chance of being selected. B) It is a non-uniform probability model because each color has an equal chance of being selected. C) It is a uniform probability model because each color does not have an equal chance of being selected. D) It is a non-uniform probability model because each color does not have an equal chance of being selected.
Answers
Answer:
B it is a non-uniform probability model because each color has an equal chance of being selected
Step-by-step explanation:
Developing a uniform probability model by assigning equal probability to all. If we select one student at random from the ten, is that a uniform then student name or grade level or color of their shirt or shoe size or different that the probability model uniform is different so that means the model is a non-uniform

find the area of each circle (use pi =3.14)
16mm
Answers
Answer:
200.96
803.84
Step-by-step explanation:
I wasn't sure if 16mm was the radius or diameter. If it's the diameter then use the first answer. If it was the radius then use the second answer.
In order to find the area of a circle use equation
[tex]A=\pi r^2[/tex]
r = radius, which is half of the line along the circle. If you have the diameter simply divide it by two and you have the radius.
Angle E and angle H are supplementary. If angle E has a measure of 156 degrees, find the measure of angle H
Answers
Answer:
24 degrees
Step-by-step explanation:
Supplementary angles sum up to give 180°
E + H = 180°
156 + H = 180
H = 180 - 156
H = 24°

Answer: 10 < x < 60, or x is from 10 to 60
Step-by-step explanation: A domain of a graph consists of all of the input values shown on the x-axis while the range consists of all of the output values shown on the y-axis. Since the question asks to find the domain, you should look at the values of the graph from left to right. The domain includes all real numbers. Notice the black horizontal line on the graph and match up the beginning of it and the end of it with the values on the x-axis. The line begins at an x-value of 10 and ends at an x-value of 60; therefore, the domain (x-values) is from 10 to 60.

A gas container in the shape of a cone has a height of 12 inches and a maximum diameter of 8 inches. When the container is filled to three-quarters of its height, what is the volume of the gas in the container, to the nearest tenth of a cubic inch.
Answers
Answer:
150.9 cubic inches
Step-by-step explanation:
volume of he gas = volume of a cone x 3/4
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius
h = height
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
8/2 = 4 inches
1/3 (22/7 x 4^2 x 12) = 201.142857 in^3
volume of the gas = 3/4 x 201.142857 in^3 = 150.9 in^3
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Jacob sold 40 candy bars and made $65. He sold two types of
bars - chocolate for $2 each and peanut butter for $1 each.
How many of each type of candy bar did Jacob sell?
Answers
Answer:
Jacob sold 25 bars - chocolates and 15 peanut butter.
Step-by-step explanation:
Jacob sold 40 candy bars.
Let the bars - chocolate be x and peanut butter be y and made $65.
Now,
x + y = 40 ...(1)
2x + y = 65 ...(2)
Now, From equation (1) we get,
x + y = 40
x = 40 - y
Now, put the value of x = 40 - y in equation (2) we get,
2x + y = 65
2(40 - y) + y = 65
80 - 2y + y = 65
y = 80 - 65
y = 15
Now, put the value of y in equation (1)
x + y = 40
x + 15 = 40
x = 40 - 15
x = 25
The bars - chocolate = x = 25 and
peanut butter = y = 15
Thus, Jacob sold 25 bars - chocolates and 15 peanut butter.

Juan compro un plasma en cuotas que costó $8000 si le faltan pagar 3 cuotas y ya pagó $6500 ¿cual es el valor de cada cuotas fijas?
Answers
Answer:
El valor de cada cuota fija es de $500.
Step-by-step explanation:
Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:
8000-6500=1500
1500/3=500
De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.
