You may use cos 60° or sin 30°. Let's use cos 60°.
cos 60° = opp/hyp = (2 mm)/j
or
j = (2 mm)/(cos 60°) = 4 mm

You see 2x2 = 4 right and since this is operation 2 / 10 = 5 and 6-5 = 1 so add 1 and that gives you 5
2x2 = 4 / 10/2 = 5 / 6-5 = 1 +4 = 5
Answer:

Assuming that there is no real preference between these 5 flavors, for which of these flavors does the experimental probability differ the most from the theoretical probability?
Answers
Answer:
Between Chocolate and Banana
Step-by-step explanation:
Theoretically, I think the experimental probability differs the most between chocolate ice cream flavor and banana ice cream flavor because out of the people surveyed, most people love chocolate and the least love banana.

Solve the following system of equations using substitution.
4x + 2y = 12
x = y + 3
Answers
Answer:
x = 3
y = 0
Step-by-step explanation:
The method of substitution is when one solves an equation for one of the variables, and then substitutes the expression into the other equation. After doing so, one will solve the other equation for the remaining variable and then backsolve for the first variable.
4x + 2y = 12
x = y + 3
The second equation is already sovled for parameter (x), subttiute this into the other equation,
4(y + 3) + 2y = 12
Distribute,
4y + 12 + 2y = 12
Simplify,
6y + 12 = 12
Inverse operations,
6y + 12 = 12
-12
6y = 0
/6
y = 0
Backsolve for (x), substitute the value of (y) into the equation for (x) and solve,
x = y + 3
x = 0 + 3
x = 3
Answer: look at the picture, sorry I can’t solve x = y + 3 for x.

Um veículo consome 2,25 litro de combustível em 33,75 quilômetro percorrido. Quanto quilômetro o veículo percorre em um litro de combustível?
A)5
B)7
C)10
D)15
PS: por favor explicar a resposta
Answers
Answer:
15
Step-by-step explanation:
1) we can use a proportion
2.25 : 33.75 = 1 : x
in a proportion the product of the terms nearest to equal is equal to the therms furthest than equal
33.75 * 1 = 2.25 * x
x = 33.75/2.25 = 15

A tepee is designed to have a diameter of 10 feet and the volume of 419 ft.³ at what height the support poles crossed with some of the tepee correctly?
Answers
Answer:
The required height is equal to 5.33 feet.
Step-by-step explanation:
Given that,
Diameter, d = 10 feet
Volume, V = 419 ft.³
We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.
The tepee is in the form of a cylinder. The volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]
So, the required height is equal to 5.33 feet.

Answers
Answer:
first option
Step-by-step explanation:
Given
y = 2(x - 3)² + 1
Rearrange making x the subject
Subtract 1 from both sides
y - 1 = 2(x - 3)² ( divide both sides by 2 )
[tex]\sqrt{\frac{y-1}{2} }[/tex] = (x - 3)² ( take the square root of both sides )
± [tex]\sqrt{\frac{y-1}{2} }[/tex] = x - 3 ( add 3 to both sides )
± [tex]\sqrt{\frac{y-1}{2} }[/tex] + 3 = x
Change y into terms of x with x being the inverse, that is
[tex]f^{-1}[/tex] (x) = ±[tex]\sqrt{\frac{x-1}{2} }[/tex] + 3

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.
So, a traingle is 180 degrees.
A line is also 180 degrees.
We know that the angles that make up the triangle are 46, 90, and a missing angle
We need to find the missing angle to find x
To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.
So:
180-90
=
90
90-46
=
44
So we know the missing angle is 44 degrees.
Let subtract the missing angle(44 degrees) by the 180 degrees of the line:
180-44
=
136
THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER
So x equals 136. This is the missing angle x.
So, remember, both the line and the traingle are 180 degrees.
They both need to find the missing value, which we know is 44
The rest of both the triangle and line is 136 degrees.
Well, 136 degrees on the triangle is the known 90+46 degrees.
Since this will be the same on the line, we can think of x as:
90+46
This looks like answer 1.
Hope this helps! :)

the volume of the square pyramid is ___ cubic meters
Answers
20X30=6000
Answer:
6000 m^3
Step-by-step explanation:
The basic formula for the area of a pyramid is 1/3 * b * h
where b is the base and h is the height.
The base is a square, so, we can find the area by squaring the side:
30^2 = 900.
Now, we can plug the values we have into the formula from above:
1/3 * 900 * 20
6000 m^3
