Answer:
50%
Step-by-step explanation:
In order to change a decimal into a percent, move the decimal to the right twice and add a percent sign
0.5 = 5.0 once
5.0 = 50.0 twice
And add a percent sign 50%
Answer:
Your answer would be 50%
Step-by-step explanation:
you would move the 5 to the left 2 times let me show you.
0.5 = 05. then 05. = 50. which would be 50%

Una autopista atraviesa un cerro mediante un túnel que tiene forma de arco parabólico, tiene 4 metros de altura ¿Cuál es la altura máxima que puede tener un camión de transporte que tiene 2 metros de ancho para pasar sin atorarse?
Answer:
supongo que < 3m
Step-by-step explanation:
el túnel tiene forma de arco parabólico, pero no aclara qué coeficiente tiene el término [tex]x^{2}[/tex], ej: si es -[tex]x^{2}[/tex], ó -0.5 [tex]x^{2}[/tex], ó -0.1 [tex]x^{2}[/tex], ...
Suponiendo que tuviese coeficiente -1, entonces la ecuación del puente es:
f(x) = -[tex]x^{2}[/tex] + 4
Tomamos el valor de f(x=1) = f(x=-1), porque suponiendo que el camión va por el centro del túnel, y teniendo 2m de ancho, queda 1m hacia cada lado:
f(x=1) = f(x=-1) = 3
Con lo cual si el camión tiene 3m de alto choca con la curva parabólica que forma el túnel.
Solve the Inequality for M:
1 + m/3 < 6
1 + m/3 < 6
Take 1 off both sides:
m / 3 < 5
Times both sides by 3:
m < 15
A group of friends are going to see a movie. The admission cost is $8 per person. The table below represents the number of friends and the total cost. Movie Costs Number of Friends, (x) 2 3 4 5 Total Cost in Dollars, (y) Which set of ordered pairs can be written from the table? (2, 10), (3, 11), (4, 12), (5, 13) (2, 16), (3, 24), (4, 32), (5, 40) (10, 2), (11, 3), (12, 4), (13, 5) (16, 2), (24, 3), (32, 4), (40, 5)
Answer:
B) (2, 16), (3, 24), (4, 32), (5, 40)
Step-by-step explanation:
1 ticket costs $8. 8 x 2 = 16, so 2 tickets cost $16. 8 x 3 = 24, so 3 tickets cost $24. The same thing goes for 4 tickets, and 5 tickets.

Answer:
5p
Step-by-step explanation:
p+4p can be written as 1p+4p. And 1p+4p=5p because 1+4=5.
What is the slope of line that passes through the pair of points (4,7,(7,-2)
Answer:
The slope from point (4,7) and (7,-2) is (9,-3)
Step-by-step explanation:
If you plot both points on a graph and go from the (7,-2) one to the (4,7) you would go up 9 and to the left 3 which is why it is negative. It is rise over run

What is the equation of the line that passes through the point (-4,-4) and has a
slope of 5/4?
Answer:
The answer is y= 5/4x+1
Step-by-step explanation:
y=mx+b
-4=5/4(-4)+b
-4=-5+b
+5 +5
1=b
So the equation of the line that passes through the point (-4,-4) and has a slope of 5/4 is y=5/4x+1 .
Rate of change is the same as what?
What does p equal in this equation and how: -p-7p=6(-2p+10)-(12-2p)
Answer:

Bianca wrote the steps for her solution to the equation 2.3 + 8(1.3x – 4.75) = 629.9. She left out the description for the last step. A table titled Bianca's Solution with 2 columns and 5 rows. The first row has the entries, blank, Steps, Resulting equations. The second row has the entries, 1, Use the distributive property to simplify, 2.3 plus 10.4 x minus 38 equals 629.9. The third row has the entries 2, Combine like terms, 10.4 x minus 35.7 equals 629.9. The fourth row has the entries, 3, Use the addition property of equality, 10.4 x equals 665.6. The fifth row has the entries, 4, blank, x equals 64. What is the missing step of her solution? Add 10.4 to both sides. Add negative 10.4 to both sides. Multiply both sides of the equation by 10.4. Divide both sides of the equation by 10.4.
Answer:
It is d!
i hope that you find this helpful! :D
The missing step for solution of the expression is,
⇒ Divide both sides of the equation by 10.4.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We have been given an expression:
2.3 + 8(1.3x - 4.75) = 629.9
Hence, We will solve the above equation for x as;
First distribute the parenthesis over 8 we get:
2.3 + 10.4x - 38 = 629.9
Now, subtract 2.3 on right hand side of the above equation we get:
10.4x - 38 = 629.9 - 2.3
10.4 x = 627.6 + 38
10.4 x = 665.6
Hence, the last step would be divide by 10.4 to get the value of x
x = 64
Therefore, option 4th is correct.

Answer:
See below
Step-by-step explanation:
You know that he spent 1/3 of his earnings, and then 1/4. After this, he has $28.90. You can write the equation like this:
1/4(x * 1/3) = $28.90.
If you need to solve it:
1/4 * 1/3x = 28.90
1/12x = 28.90
x = 346.80

∠ and ∠ are supplementary angles. If ∠ = (2 − 30)° and ∠ = 4, find the measure of the larger angle
Answer:
We get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle
Step-by-step explanation:
we have ∠A = (2x − 30)° and ∠B = 4x, and we need to find measure of larger angle. And ∠A and ∠A are supplementary angles.
If the angles are supplementary there sum is equal to 180° i.e ∠A + ∠B = 180°
So, First we have to find the value of x. and then we can determine larger angle.
We know: ∠A + ∠B = 180
2x-30+4x=180
6x-30=180
6x=180+30
6x=210
x=210/6
x=35
So, value of x is x=35
Now finding ∠A and ∠B
∠A = (2x − 30)°
∠A = (2(35) − 30)°
∠A = (70 − 30)°
∠A =40°
and ∠B = 4x
∠B = 4(35)
∠B = 140°
So, we get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle
