Answer:
502.4
Step-by-step explanation:
Use tangent because the side you know and the side with x are both legs.
Do 203/tan(22) and you should get your awnser.
You devide by 203 because the rule is opposite over ajacent and 203 is the opposite side.
The answer is x = 10, y = 10.
Step 1: rearrange the second equation for y.
Step 2: substitute y from the second equation into the first equation.
Step 3. Calculate y.
Step 1.
<span>The second equation is: 6x + 3y = 90
Divide both sides of the equation by 3:
(6x + 3y)/3 = 90/3
6x/3 + 3y/3 = 30
2x + y = 30
Rearrange the equation:
y = 30 - 2x
Step 2.
</span>Substitute y from the second equation (y = 30 - 2x) into the first equation:
<span>15x + 9y = 240
15x + 9(30 - 2x) = 240
15x + 270 - 18x = 240
15x - 18x = 240 - 270
-3x = -30
x = -30/-3
x = 10
Step 3.
Since </span>y = 30 - 2x and x = 10, then:
y = 30 - 2 * 10
y = 30 - 20
y = 10
121 of the green beans will be shorter than 13 centimeters.
First, we need to evaluate the expression below to find the z-score.
(13 - 11.2) / 2.1. = 0.86
The matching percent for this z-score is 0.8051.
Multiplying 0.8051 by 150 gives us about 121 green beans.
Answer:
Step-by-step explanation:
If we know that D is the midpoint, then 2x + 7 = 4(x-3). Doing the algebra on that gives us
2x + 7 = 4x - 12 and
19 = 2x so
x = 9.5
Maybe search up Algebra calculator and type in the equation? idk
