You can use sen30° to solve it:
Since Sen=Opposite side / diagonal
Sen30° = OS/D
1 / 2 = x / [tex]2\sqrt{3}[/tex]
2x = [tex]2\sqrt{3}[/tex]
x = [tex]\sqrt{3}[/tex]

Answer:
1.9
Step-by-step explanation:
just put it into he calculator, because with 3 above the square root.
Answer:
Approximately 1.9 (rounded to the nearest tenth)
Step-by-step explanation:
First, we are left off with the equation:
[tex]y^{3} = 7[/tex]
We know we want to solve for y. So, let's do the opposite of what is being done to y. In other words, let's find the cube root of [tex]y^{3} = 7[/tex].
[tex]\sqrt[3]{y^3} = \sqrt[3]{7}[/tex]
Then, the [tex]\sqrt[3]{y^3}[/tex] just simplifies to y. On the other side, we cannot find the cube root of 7 in our minds, so that is why it tell us to use a calculator. So...
y = 1.9
Therefore, the cube root of 7 is around 1.9. Hope this helps!
The function g(t)=−16t2+vt+h represents the height of an object, g, in feet, above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet. A model rocket is launched off the ground at an initial velocity of 80 feet per second. Part A: Write a function that can be used to describe the flight of the model rocket. Part B:What domain makes sense for this function in context?
Answer:
A) g(t) = - 16*t² + 80*t
B) domain is ( 0 ≤ t ≤ 5 )
Step-by-step explanation:
A) for the model rocket
h = 0 and v = 80 feet/sec
Then the equation g(t) = -16*t² + v*t + h
became
g(t) = - 16*t² + 80*t + 0 g(t) = - 16*t² + 80*t
B) The equation g(t) = - 16*t² + 80*t is defined for all real numbers then the domain interval for t is ( -∞ , ∞ ). Now in our case, a model rocket was launched is not possible to get negative values for g(t) then the biggest value for t = 5 from
-16*t² + 80*t ≥ 0
-16*t ≥ -80 16*t ≤ 80
t ≤ 5
And the domain is ( 0 ≤ t ≤ 5 )

in class slope and y intercept 50 points
Answer:
Slope =-3, y intercept =4
Step-by-step explanation:
y2-y1/x2-x1 = slope
4-(-2)/0-2=6/-2 or -3
y intercept is where line crosses y axis so it is 4.
Answer:
Slope: -3, y-intercept: 4
Explanation:
=> In order to find slope when a graph is given, the formula would be: [tex]\frac{rise}{run}[/tex](pronounced as "rise over run")
Rise = change in y-value = -3
Run = change in x-value = 1
Slope = [tex]\frac{rise}{run}[/tex] = [tex]\frac{-3}{1}[/tex] also could be written as -3
=> Now, to find the y-intercept, find a value on the graph where the line touches the y-axis, that's where x = 0, which would be your y-intercept;
Here the line touches the y-axis at "y = 4", this is also where x = 0;
therefore y-intercept = 4

Every person has blood type O, A, B, or AB. A random group of people are blood-typed, and the results are shown in the table. A 2-column table with 4 rows is shown. The first column is labeled Blood Type with entries O, A, B, AB. The second column is labeled Number of People with entries 22, 20, 6, 2. Use the table to determine the following probabilities. The probability that a randomly chosen person from this group has type B is . The probability that a randomly chosen person from this group has type AB is . The probability that a randomly chosen person from this group has type B or type AB blood is
Answer:
3/25 for type B, 1/25 for type AB, and 4/25 for both
Step-by-step explanation:
O goes to 22
A goes to 20
B goes to 6
AB goes to 2
22+20+6+2 = 50, so (number of people with a certain blood type)/50 = the answers for each question.

3.072 > 3.2
728.307 > 729.07
12.040 = 12.04
531.135 < 531.315
Answer:
No, no, yes, yes
Step-by-step explanation:
3.072 is not bigger than 3.2, so incorrect (no)
728.307 is not bigger than 729.078, so incorrect again (no)
12.040 does equal 12.04, so correct (yes)
531.135 is smaller than 531.315, so correct (yes)
How do I solve this problem?
Answer:
21, 18, 15
Step-by-step explanation:
First term = a1
Second term = a2
Third term = a3
a1 = 21
a2
= a + d
= 21 - 3
= 18
a3
= a + 2d
= 21 + 2 ( - 3 )
= 21 - 6
= 15
The first 3 terms are 21, 18, 15.

What is the first step in simplifying the expression below ?
3 + 4 (6 - 8)^2
O 3 Plus 4
O 3 Plus 16
O 6 Minus 8
O Multiply -2 by itself
O Multiply by 4
Answer:
Step-by-step explanation:
The very first step is to take (6 - 8) = - 2 Do the brackets first.
Now square the result (-2)^2 = 4 Multiply by 4
4*4 = 16 These fours are different. The first is the brackets, The second is what is out side the brackets.
Last step: 16 + 3 The answer is 19.
19 is not what you asked for, but it's a good idea to see how to continue.
A piece of land is 3 miles wide. It is 4 1/6 times as long as it is wide. How long is the piece of land?
Answer: [tex]\frac{25}{2}\ \text{miles}[/tex]
Step-by-step explanation:
Given
A piece of land is 3 miles wide
It is [tex]4\ \frac{1}{6}[/tex] times as long as it is wide
Suppose width be b
So, length becomes [tex]\frac{24+1}{6}b[/tex]
Also, [tex]b=3\ \text{miles}[/tex]
[tex]\therefore \text{Length is }l=\dfrac{25}{6}\times 3\\\\\Rightarrow l=\dfrac{25}{2}\ \text{miles}[/tex]
john bought 3 1/2meters of wire it he used 1 5/6 meters in wire a job how many meters of qire was leftover
Answer:
1 (2/3)meter
Step-by-step explanation:
3(1/2) = 7/2 = 21/6
1(5/6) = 11/6
21/6 - 11/6 = 10/6 = 5/3 = 1 (2/3)

<1 and <2 form a linear pair. The measure of <1 = (2x+8) and the measure of <2 = (8x + 22). What is the measure of <1?
Answer:
Step-by-step explanation: Since the given problem states that the two angles, angle 1 and angle 2 form a linear pair, this means that they form a 180° line, so that:
measure angle 1 + measure angle 2 = 180°
Since measure of angle 2 is six more than twice the measure of angle 1, therefore:
measure angle 2 = 2 (measure angle 1) + 6
hence, substituting this into the first equation:
measure angle 1 + 2 (measure angle 1) + 6 = 180
3 (measure angle 1) = 174
measure angle 1 = 58°
Therefore,
measure angle 2 = 2 (measure angle 1) + 6
measure angle 2 = 2 (58°) + 6
measure angle 2 = 122*

A candle on a table is 6 inches tall and burns at a rate of .8 inches per hour. How many hours will it take for the candle to burn down to a height of 1.2 inches?
Answer:
6 hours
Step-by-step explanation:

Answer:
C)
Step-by-step explanation:
in order to understand which triangle would lie on the given line we should figure out the slope of the given line first
remember that,
[tex] \displaystyle m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]
from the graph let's take two points where the line passes i.e (0,0) and (4,6)
substitute:
[tex] \displaystyle m = \frac{6- 0}{ 4 - 0} [/tex]
simplify substraction:
[tex] \displaystyle m = \frac{6 }{ 4 } [/tex]
reduce fraction:
[tex] \displaystyle m = \frac{3}{ 2} [/tex]
now we need a triangle which tan ratio equal to the slope in that case we can consider the third triangle
[tex] \displaystyle \tan( \theta) = \frac{30}{20} [/tex]
reduce fraction:
[tex] \displaystyle \tan( \theta) = \frac{3}{2} [/tex]
since the tan ratio of the third triangle equal to the slope of the line
hence, our answer is c

HELP ME ASAP I NEED HELP SO BAD
Answer:
x = -3
Step-by-step explanation:
5x + 4y = 1
y = 1 - x
• Substitute (1 - x) into y:
5x + 4(1 - x) = 1
• Distribute:
5x + 4 - 4x = 1
• Combine like terms:
x + 4 = 1
• Subtract the 4 to solve for x:
x = -3
