Step-by-step explanation:
Tan(14/12)=angle of ONP
Tan(42/X)=angle of LNM
singe those angels are the same;
Tan(14/12)=Tan(42/X)
14/12=42/X
14*X=42*12
X=(42*12)/14
X=36
What is an equation of the line that passes through the points (-5, -1) and (5, 3)?
What is the solution
Answer:
(3,2)
Step-by-step explanation:
If you look at the x-axis it 3 to the right and your y-axis is 2 up and so the pair is (x is first, y is second) so it (3,2).
What are the areas please
1. 105 units²
2. 78 units²
Step-by-step explanation:
1.
Since the middle is a square, the base of all 4 triangles are equal.
Let x be the height of the triangles.
The height of the triangle can be defined as:
15 = 7 + x + x
15 = 7 + 2x
15 - 7 = 2x
x = 8/2
x = 4
Area = area of square + 4(area of triangle)
= (7 x 7) + 4(1/2(7)(4))
= 49 + 56
= 105 units²
2.
Area = area of triangle + area of rectangle
area of triangle = ½ x base x height
base = 4 + 4 + 4
= 12
height = 15 - 6
= 9
area of triangle = ½ x 12 x 9
= 54 units²
area of rectangle = 6 x 4
= 24 units²
Area = 54 + 24
= 78 units²
Paulo comprou 60 maçãs e 24 laranjas. Ele pretende organizar essas frutas em embalagens plásticas. Em cada embalagem plástica ele colocará apenas um tipo de fruta e na maior quantidade possível, para que todas as embalagens fiquem com a mesma quantidade de frutas. Qual a quantidade de embalagens plásticas que Paulo irá precisar para organizar essas frutas? 7. 12. 84. 120.
Responder:
7
Explicação passo a passo:
Obtemos o maior fator comum de ambas as frutas:
Apple = 60
Laranja = 24
Fatores de:
60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 e 60
24 = 1, 2, 3, 4, 6, 12 e 24
O maior fator comum é 12
Por isso,
Número de malas necessárias para:
Maçãs = 60/12 = 5
Laranjas = 24/12 = 2
Total de sacos plásticos necessários = 5 + 2 = 7

What is the vertex of the parabola with the equation y
3x2 + 2x – 8?
Answer:
Step-by-step explanation:
If you're tasked to do this mathematically, you have to complete the square to get it into vertex, or work, form. Do that by first setting the equation equal to 0 then moving over the constant:
[tex]3x^2+2x=8[/tex] Next you have to have a +1 as the leading coefficient, and ours is a 3, so we factor it out:
[tex]3(x^2+\frac{2}{3}x)=8[/tex]. Now take half the linear term, square it, and add it in to both sides. Our linear term is 2/3. Half of 2/3 is 2/6 which reduces to 1/3. Squaring 1/3 gives us 1/9, so that's what we add in.
[tex]3(x^2+\frac{2}{3}x+\frac{1}{9})=8+\frac{1}{3}[/tex] to the right of the equals sign we added in 3*1/9 which is 3/9, which reduces to 1/3. Now we clean up both sides. The right side is easy; the left side, not so much. The reason we do this (complete the square) is to get a perfect square binomial on the left. When we re-write the left side into that perfect square binomial, we get
[tex]3(x+\frac{1}{3})^2=\frac{25}{3}[/tex] Now we move the constant back over and set the parabola back equal to y:
[tex]y=3(x+\frac{1}{3})^2-\frac{25}{3}[/tex] which shows us that the vertex is
[tex](-\frac{1}{3},-\frac{25}{3})[/tex]

The difference between an observational study and an experiment is that:
A. in an observational study, only one group is studied, and in an experiment, two groups are studied.
B. in an observational study, the researchers do not control treatment, and in an experiment, they do.
C. in an experiment, cause-and-effect is analyzed, and in an observational study, it is not.
D. in an experiment, one group is studied over a short period of time, and in an observational study, the group is studied over a longer period of time.
Answer:
B
Step-by-step explanation:
An experiment is a study carried out in a controlled environment where the person undertaking the research hopes to understand cause and effect between the independent and dependent variables. An example of a experiment is the palovian experiment
The independent variable is the variable that the person carrying out an experiment changes or manipulates. the independent variable usually have a direct effect on the dependent variable
The dependent variable is the variable that is being measured in an experiment. It is usually affected by the independent variable
Observational study is the study where the researcher observes and measures cause and effect between independent and dependent variables without trying to control or influence the population

In a Survey of 500 people , 350 people dank only one drink. 60 people dink none them. Find the number of people who drink both ,
Answer:
90
Step-by-step explanation:
350+60= 410 & 500-410=90
Answer: The number of people who drank both is 90
This is because we need to subtract 350 people from 500 people, because we know that they didn't drink the drink. We have 150 people left. Another 60 people don't drink the drink at all, so we need to subtract that from the remaining 150 people left. We get the solution of 90 people who could only have drank both drinks based of of the givens you have provided.

Two jackets have a combined cost of $98. Jacket a costs $12 less than jacket b. How much does each jacket cost?
Answer:
Jacket A costs 43$
Jacket B costs 55$
Step-by-step explanation:
According to the Question,
Given, Two jackets have a combined cost of $98. Jacket 'A' costs $12 less than jacket 'B'. Thus, if the jacket B Cost 'X' So, Jacket A costs 'X-12'.Therefore, Jacket A + Jacket B = 98
X-12+X = 98
2X = 110
X = $55 ( Cost of jacket B) & Cost of Jacket A is 55-12 = 43$ .

Step-by-step explanation:
The independent variable is plotted on the horizontal axis. If you want to find out what it is, read the axis label.
The dependent variable is plotted on the vertical axis. If you want to find out what it is, read the axis label.
To find the distance from home at some time, look up that time on the horizontal axis, and read the corresponding distance value from the graph. The maximum distance from home is the peak value of the graph.
"Stopping" means that distance doesn't change, even while time continues to increase. The curve is horizontal where the person is stopped.

a shirt normally sells for $25. a sales tax of 8% is added to the shirt. what is the total cost of the shirt including the tax
a)20.00
b)$2.00
c)$27.00
d)$23.00
Answer:
C.$27.00
Step-by-step explanation:
First, you have to multiply the percentage by the starting number, 8%*25 = 2;
Then you have to add that answer (2) to the starting number (25), 25+2 = 27;
So the total cost of the shirt would be $27.00.

Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, acute, obtuse, scalene and right angled triangle.
If two sides of a triangle are unequal, then the value of the angles opposite to these sides are unequal, and the greater angle is that which is opposite to the greater side.
BC > AC > AB
Therefore the angles opposite are proportional to this sides. Hence:
∠A > ∠B > ∠C
