Answers

Answer:It's 18

Step-by-step explanation:Multiply 7 and 6 to get 42

Subtract 10 from 13 to get 3

Divide 42 by 3 to get 14

Add 14 and 4 to get 18

Answer:

18

Step-by-step explanation:

First do the ones inside the bracket (13-10)=3

Second divide 6 by the answer you get from the first part 6÷3=2

Third multiply the answer from second with 7×2=14

Then add the answer you get from the third one to 4+14=18

Mathematically

7×6÷(13-10)+4

= 7×6÷3+4

Find the length of side a in simplest radical form with a rational denominator.

Answers

Answer:

x = 5.5

Step-by-step explanation:

Using a trig ratio, you can use sin, which is opposite over hypotenuse. [tex]sin(30)\textdegree=\frac{x}{11}[/tex]

Now, multiply both sides by 11

[tex]11\cdot sin(30)\textdegree=x[/tex]

this simplifies to x = [tex]\frac{11}{2}[/tex] or 5.5.

Since sin30 is [tex]\frac{\pi}{6}[/tex] radians, it can be written as [tex]\frac{11\pi}{6}[/tex].

5x + 8y = 31

Answers

Step-by-step explanation:

1.) Move the 5 to the other side of the equation

8y = -5x + 31

2.)

Divide by 8

y= .625x + 3.8

Answer:

5x + 8y = 31

8y = -5x + 31

y = -0,625x + 3,875

    y = mx + b

    m = slope

    b = intercept

y = -0,625x + 3,875

slope = -0,625

intercept = 3,875

Step-by-step explanation:

The bag has a total of (4+2+3+5) = 14 balls. Set up the proportions:

Removing 1 yellow, 1 red, 1 green, and 1 blue = [tex]\frac{3}{14} \cdot \frac{4}{14} \cdot \frac{2}{14} \cdot \frac{5}{14} =\frac{15}{4802}[/tex]

Removing 1 blue, 1 green, 1 green, and 1 yellow = [tex]\frac{5}{14} \cdot \frac{2}{14} \cdot \frac{2}{14} \cdot \frac{3}{14} =\frac{15}{9604}[/tex]

Removing 1 red, 1 red, 1 yellow, and 1 yellow = [tex]\frac{4}{14} \cdot \frac{4}{14} \cdot \frac{3}{14} \cdot \frac{3}{14} =\frac{9}{2401}[/tex]

RelationDomainRangeFunctionVertical Line TestFunction NotationPractical DomainPractical Range

===========================================================

Explanation:

A relation is basically anything where we connect one variable to another. Usually there are math operations involved to have a predictable rule. For example, y = x+5 says "add 5 to the x input to get the y output". But we won't always have a rule like this to connect x and y.The domain is the set of allowed inputs (x values). For example, if we had the function y = 1/x, then we can plug in anything but x = 0. This is to avoid a division by zero error.The range is the set of allowed output y values. You can use a graph to determine the range, or find the domain of the inverse (assuming one exists).This is basically saying each input goes to exactly one output only. If such a thing happens, then the relation is a function.A visual way to test if you have a function is to use the vertical line test. If you can pass a vertical line through more than one point, then it is said to have failed the vertical line test and we don't have a function. Failing the vertical line test shows that a particular x value leads to multiple y outputs.Function notation is when we replace y with something like f(x) so the function name is a bit more descriptive.Let's say we had the function f(x) = 100/x. The x represents the number of people, and f(x) is the average cost per person. Before I mentioned that the domain is anything but 0, to avoid a division by zero error. Realistically, we also would make x the set of positive whole numbers (1,2,3,4,...) since x is the number of people. This is one example where a theoretical domain shrinks down to a more practical one. Since the domain shrinks in problem 7, the range is likely to shrink as well. Use a graph or table to see why this happens.

From the question, we are to prove that ∠BOC ≅ ∠DOE

We are given that

By vertical angles theorem, we can observe that

∠AOB ≅ ∠DOE and ∠BOC ≅ ∠EOF
