Find the volume of the figure
Answer:
132 yd³
Step-by-step explanation:
To find the volume of a triangular prism, use this equation: V = (1/2bh) * h
V = (1/2(11 * 4)) * 6
Step 1: Multiply 11 by 4 to get 44.
V = (1/2(44)) * 6
Step 2: Multiply 1/2 by 44 to get 22.
V = 22 * 6
Step 3: Multiply 22 by 6 to get 132.
V = 132
The volume of the figure is 132 yd³.

What is 2.4% as a decimal
Answer:
2.4% as decimal will be 0.024.
Step-by-step explanation:
1) To convert to a decimal, divide the percent number by 100.
[tex]2.4 \div 100 = 0.024[/tex]
2) Therefore, the decimal form is 0.024.
[tex]0.024[/tex]
2.4% is equivalent to 0.024 as a decimal.
To convert 2.4% to a decimal, we divide the percentage value by 100. In this case, we divide 2.4 by 100:
2.4% = 2.4 / 100 = 0.024
Therefore, 2.4% as a decimal is 0.024.
When we convert a percentage to a decimal, we move the decimal point two places to the left. This is because a percentage is a value expressed as a fraction of 100. So, to express 2.4% as a decimal, we divide 2.4 by 100, resulting in 0.024.
To understand this conversion, consider that 100% is equivalent to the whole value, which is represented as 1 in decimal form. Any percentage less than 100% will be a fraction of that whole, expressed as a decimal less than 1. In this case, 2.4% is a small fraction of 1, which is 0.024.

Resuelve usando el método de sustitución o el de eliminación. Para un juego de baloncesto se vendieron 1,850 boletos. Se recaudo un total de $ 8,800. Si los boletos de niños cuestan $ 4 y los de adultos cuestan $ 6. ¿Cuántos boletos de cada clase se vendieron?
Answer:
Se vendieron 700 boletos para adultos y 1,150 boletos para niños.
Step-by-step explanation:
Primero tenemos que definir dos variables:
x = número de boletos de niños vendidos
y = número de boletos de adultos vendidos.
Entonces podemos escribir la recaudación total como:
x*$4 + y*$6
Y sabemos que la recaudación total fue $8,800, entonces:
x*$4 + y*$6 = $8,800
También sabemos que se vendieron 1,850 boletos, entonces:
x + y = 1,850
Entonces tenemos el sistema de ecuaciones:
x*$4 + y*$6 = $8,800
x + y = 1,850
En este caso podemos utilizar el método de sustitución, para ello primero debemos aislar una de las variables en una de las ecuaciones.
Si aislamos x en la segunda ecuación tenemos:
x = 1,850 - y
Ahora podemos sustituir esto en la otra ecuación para obtener:
(1,850 - y)*$4 + y*$6 = $8,800
Ahora podemos resolver esto para y.
$7,400 - y*$4 + y*$6 = $8,800
y*$2 = $8,800 - $7,400 = $1,400
y = $1,400/$2 = 700
Entonces se vendieron 700 boletos para adultos.
Ahora podemos usar la ecuación x = 1,850 - y para obtener el valor de x.
x = 1,850 - y
x = 1,850 - 700 = 1,150
Se vendieron 1,150 boletos para niños.

Can anyone answer this?
Step-by-step explanation:
a) First we will convert 150km/hr to m/s.
[tex] \frac{150km}{1hr} = \frac{(150 \times 1000)m}{(1 \times 60)s} \\ = \frac{150000m}{60s} \\ = 2500m \: per \: second[/tex]
=2500m/s, which is the initial speed of the plane.
b)Final Speed of plane = Speed when it stopped.
= 0m/s.
c)Time taken to stop = 3 seconds.
d)Using the kinematic equation,
v = u + at,
where v = Final Speed = 0m/s
u = Initial Speed = 2500m/s
a = acceleration
t = time taken = 3 seconds
Substitute v, u and t to find a.
[tex]0 = 2500 + 3a \\ 3a = - 2500 \\ a = - 2500 \div 3 \\ = - 833 \frac{1}{3} \frac{m}{ {s}^{2} } [/tex]

How does 5x + 15 = 45
HELP PLZ
Answer:
When finding these problems we always have to do the opposite of the operation shown.
In this case its:
5x + 15 = 45
Subtract 15 from both sides (we start off with constants and numbers that are being shown) The reason why its subtraction is because since your adding 15 to 5x the opposite of that is subtraction so use the number shown by itself and subtract it from both sides.
5x = 30
Divide by 5 on both sides since the opposite of 5x is division (only use the number that is shown) We have to get rid of all the numbers on the left.
therefore you'll be left with:
X = 6
Answer:
X=6
Step-by-step explanation:
5x+15=45
5x=45-15
5x=30,divide both sides by 5 to get x
x=6

Write a linear equation in slope intercept form using the given point and slope.
(6,-6); slope = 2/3
Answer:
2/3x-10
Step-by-step explanation:
y=mx+b
y=2/3x+b
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(6,-6). When x of the line is 6, y of the line must be -6.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 2/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (6,-6).
So, why not plug in for x the number 6 and for y the number -6? This will allow us to solve for b for the particular line that passes through the point you gave!.
(6,-6). y=mx+b or -6=2/3 × 6+b, or solving for b: b=-6-(2/3)(6). b=-10.
so, y=2/3x-10
what is the average rate of change of the function f(x) over the interval [1,3] rounded to the nearest whole number f(x)=6(2.5)
Answer:
[f(1) - f(3)] / [1–3]
Step-by-step explanation:
Formula
f(x) = 6(2.5)
How to find
The average rate of change over the interval [a,b], or the secant line between the points a and b on the function f(x), is [f(a) - f(b)]/[a-b]. So, substitute a for 1 and b for 3, and you get [f(1) - f(3)] / [1–3]. The quotient of that is your average rate of change.
