Eric had 15.3 feet of fishing line. He cut off a piece and had 38.4 inches left. How long was the piece he cut off?
Answer:
x = 145.2
Step-by-step explanation:
Convert 15.3 ft to inches = 183.6
Exquation:
183.6 - x = 38.4
-x = 38.4 - 183.6
-x = -145.2
x = 145.2

Jim rented a truck for one day. There was a base fee of $15.95, and there was an additional charge of 78 cents for each mile driven. Jim had to pay $186.77 when he returned the truck. For how many miles did he drive the truck?
Answer:
219 miles.
Step-by-step explanation:
Jim paid $186.77 in total.
The base fee was $15.95
$186.77 - $15.95 = $170.82
The base fee was taken care of, the rest of the money was spent on the number of miles he drove.
For each mile he needs to pay 78 cents (Aka 0.78).
$170.82 ÷ 0.78 = 219
Jim drove 219 miles.

Jake tosses a coin up in the air and lets it fall on the ground. The equation that
models the height (in feet) and time (in seconds) of the parabola is
h(t) = -16t2 + 24 + 6. Approximate the time at which the coin hits the
ground.
Answer:
[tex]t = 1.71825[/tex]
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 24t + 6[/tex]
Required
When will the coin hit the ground
When the coin hits the ground, [tex]h(t) = 0[/tex]
The expression [tex]h(t) = -16t^2 + 24t + 6[/tex] becomes
[tex]0 = -16t^2 + 24t + 6[/tex]
Multiply through by -1
[tex]16t^2 - 24t - 6 = 0[/tex]
Solve using quadratic formula
[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 16[/tex]
[tex]b = -24[/tex]
[tex]c = -6[/tex]
[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]t = \frac{-(-24)\±\sqrt{(-24)^2 - 4 *16 * -6}}{2 * 16}[/tex]
[tex]t = \frac{24\±\sqrt{576 +384}}{32}[/tex]
[tex]t = \frac{24\±\sqrt{960}}{32}[/tex]
[tex]t = \frac{24\±30.984}{32}[/tex]
Split
[tex]t = \frac{24+30.984}{32}[/tex] or [tex]t = \frac{24-30.984}{32}[/tex]
[tex]t = \frac{54.984}{32}[/tex] or [tex]t = \frac{-6.984}{32}[/tex]
[tex]t = 1.71825[/tex] or [tex]t = -0.21825[/tex]
But time can't be negative;
So:
Time to hit the ground is 1.71825 seconds

Answer:
x=26
Step-by-step explanation:
exterior angles theorem meaning they're equal to each other.
5x+7=8x-71
add 71 to 7
5x+78=8x
subtract 5x from 8x
78=3x
divide 78 and 3
x=26
to check your work plug 26 into each equation:
5(26)+7= 137°
8(26)-71= 137°
because they're the same you know that x must equal 26

Beatriz tiene el triple de la edad de Rocio.
Jesus tiene cinco veces mas años que Rocio.
Entre beatriz y Jesus suman 32 anos.
a- A partir de la edad de Rocio, escribe la edad de Beatriz y la de Jesus.
b-Expresa la suma de la edad de Beatriz y de Jesus. Añade el resultado.
c-Extrae como factor comun el numero que representa el simbolo.
d-Cuantos años tiene Rocio? Y cuantos años tienen Beatriz y Jesus?
Answer:
a) Beatriz: [tex]y = 3\cdot x[/tex], Jesús: [tex]z = 5\cdot x[/tex], b) [tex]y+z = 32[/tex], c) El símbolo (edad de Rocío) queda representado en el siguiente factor común: [tex](3+5)\cdot x = 32[/tex], d) Rocío tiene 4 años de edad, Beatriz tiene 12 años de edad y Jesús tiene 20 años de edad.
Step-by-step explanation:
a) Sean [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] las edades de Rocío, Beatriz y Jesús. Después de una lectura cuidadosa al enunciado:
(i) Beatriz tiene el triple de la edad de Rocío.
[tex]y = 3\cdot x[/tex] (Ec. 1)
(ii) Jesús tiene cinco veces más años que Rocío.
[tex]z = 5\cdot x[/tex] (Ec. 2)
b) Seguimos la misma estrategia del punto a):
Entre Beatriz y Jesús suman 32 años.
[tex]y+z = 32[/tex] (Ec. 3)
c) Sustituimos [tex]y[/tex], [tex]z[/tex] en (Ec. 3):
[tex]3\cdot x + 5\cdot x = 32[/tex]
[tex](3+5)\cdot x = 32[/tex]
[tex]8\cdot x = 32[/tex]
[tex]8\cdot x = 8\cdot 4[/tex]
[tex]x = 4[/tex]
El símbolo (edad de Rocío) queda representado en el siguiente factor común: [tex](3+5)\cdot x = 32[/tex]
d) Tal como desarrollamos en el punto c), Rocío tiene 4 años de edad.
Las edades de Beatriz y Jesús se obtiene por sustitución directa:
Beatriz
[tex]y = 3\cdot x[/tex]
[tex]y = 3\cdot 4[/tex]
[tex]y = 12[/tex]
Beatriz tiene 12 años de edad.
Jesús
[tex]z = 5\cdot x[/tex]
[tex]z = 5\cdot 4[/tex]
[tex]z = 20[/tex]
Jesús tiene 20 años de edad.

What is the measure of angle 1?
Answer:
140.25°
Step-by-step explanation:
Angle 1 and Angle (3x+12) share the exact same angle since they are congruent. Knowing this, you can replace angle 1 with (3x+12). Math tells you that supplementary angles are two angles that add up to 180 degrees.
(x-3) and (3x+12) are supplementary. Since they are supplementary and math tells me that two angles add up to 180. I can add (x-3) and (3x+12). But to finish the equation, both of these angles must equal 180.
Your equation should look something like this (it should look like this):
[tex](x-3)+(3x+12)=180[/tex]
From there you can simplify and isolate the x value to solve for x. Your x value is 42.75. But, we are not done here.
Now that we know x, which is just a placeholder, we must replace the placeholder with its actual numerical value (42.75).
3(42.75) + 12 = 140.25.
To make sure both angles equal up to 180.
Replace all x's with 42.75 and you will see that they equal 180.
[tex](3(42.75)+12)+(42.75 - 3) = 180[/tex]
[tex]180=180[/tex]✅

Write an algebraic expression for the verbal expression the sum of g squared and four.
Answer:
g^2 + 4
I literally do not know how to explain it. I solved this problem with the clues like sum and squared. I looked at where these words were located.
The algebraic expression for the sum of g squared and four is g^2 + 4.
The given statement is "the sum of g squared and four".
We need to write an algebraic expression for this statement.
What are the common algebraic signs?- Sum = add = +
- Difference = minus = -
- Divide = ÷
- Squared = [tex]x^{2}[/tex]
- cube = [tex]x^{3}[/tex]
- Square root = [tex]\sqrt{x}[/tex]
We have,
"the sum of g squared and four".
Let us separate it into two parts:
g squared - [tex]g^{2}[/tex]
Four = 4
Sum = +
So we have,
Sum of g squared and four = [tex]g^{2}[/tex] + 4.
Thus the algebraic expression for the sum of g squared and four is [tex]g^{2}[/tex] + 4.
