total mujeres 3+9=12 estudiante =40% mujeres
60% hombres =? estudiante 40% mujeres=12estudiante
3*20=60 20*20=40 por lo tanto 20%=6 estudiante
60%=3*6=18 estudiante
Total hombres y mujeres estudiante 18+12=30
how do you graph y= 3x-2
Answer:
Plug in x values into the equation. Start by making a table with x on one side and y on the other. Then, plug in an x value into the equation. We'll start by plugging in 0. This would give us y=3(0)-2, which simplifies to y=-2. Now we know that when x=0, y=-2, so write these two values in your table. Next, we can do this with more points. Let's plug in 1 for x. This gives us y=3(1)-2, which simplifies to y=1 when x=1. Again, we'll write this in our table. After we have a few pairs of x and y values, then we'll draw these points on the graph.
Step-by-step explanation:
The graph of the given linear equation, y = 3x - 2, can be drawn as shown in the coordinate plane attached below.
How to Graph a Linear Equation?To graph y = 3x - 2, choose x-values, calculate the corresponding y-values by substituting them into the equation, plot the points on a coordinate plane, and draw a straight line.
The slope (3) and y-intercept (-2) can be identified from the equation in slope-intercept form (y = mx + b).
Thus, the graph of the linear equation, y = 3x - 2, is shown below.

Find the measure of angle A
Answer:
m<A = 36 degrees
Step-by-step explanation:
we know that the top angle is 90 degrees and so (x+46) + (x + 66) = 90
simplify and we get 2x + 110 = 90
x = -10
substitute -10 for x
m<A = (-10) + 46
m<A = 36

A canary has a heart rate of about 17 beats per second. How does the canary's heart rate compare to the bat's heart rate? Explain. (Remember, there are 60 seconds in a minute.)
Answer:
A canary's heart beats around 1,000 times per minute or 16.67 times per second. A canary is a very small bird whose heart beats more than twelve times faster than yours.
While a bat's heart beats between 200 to 1,000 times per minute. That means that while the bat is flying, its heart beats at the same rate as a canary's. But when the bat is resting, its heart beats is reduced by 5 times to "only" 200 beats per minute or 3.33 beats per second.

Graph the inequality
Write the slope-intercept form of the equation of the line given the slope and the y-intercept.
Slope = -2, y-intercept = -4
Answer:
y=-2x-4
Step-by-step explanation:
So remember this y=mx+b
The M is the slope and the B is our y-intercept
So according to the picture it gave you the slope and the Y-intercept
The slope was -2 and the y-intercept was -4
So y=mx+b so subtitute the m to -2 and the b to -4
The equation should be y=-2x-4

You're throwing a party, and you ordered 15 pizzas for your guests. Your total came to
$97.50. What was your unit cost per pizza?
A.$6.50 per pizza
B.$4.95 per pizza
C.$7.25 per pizza
D.$5.75 per pizza
Answer:
A
Step-by-step explanation:
97.5 / 15 = 6.5
The unit cost is $6.50 per pizza
What is the cost per unit in math?The "Unit Price" (or "unit cost") tells you the cost per liter, per kilogram, per pound, etc. of what you want to buy. How do I calculate cost per unit?To calculate the cost per unit, add all of your fixed costs and all of your variable costs together and then divide this by the total amount of units you produced during that time period.Based on the given conditions,
formulate: $97.50 ÷ 15
Convert decimal to fraction: 975÷10÷15
Divide a fraction by multiplying its reciprocal : [tex]\frac{975}{10}[/tex] ×[tex]\frac{1}{15}[/tex]
Cross out the common factor: [tex]\frac{65}{10}[/tex]
Cross out the common factor: [tex]\frac{13}{2}[/tex]
Per cost pizza : [tex]6.5[/tex] or [tex]6\frac{1}{2}[/tex]
Hence , throwing a party , ordered 15 pizza for guest and total value of pizza is $97.50 and the cost of one per pizza is $ 6.5 .
