What is the value of a+b?

Answers

Answer 1

Answer:

125

Step-by-step explanation:

[tex]a = \frac{1}{2} \times 90 \degree \\ \\ a = 45 \degree \\ \\ b =\frac{1}{2} (360\degree - 200\degree) \\ \\ b = 80\degree \\ \\

a + b = 45 + 80 \\ \\ a + b = 125 \degree[/tex]

Solve for x. Enter your answer in interval
notation using grouping symbols.
x2 + x < 20

Answers

Answer:

x<18

Step-by-step explanation:

2+x<20

Answer:

(-5, 4)

Step-by-step explanation:

x^2 + x < 20 can be rewritten as a quadratic in standard form: x^2 + x - 20 < 0. Recognize that the graph of x^2 + x - 20 is that of a parabola that opens up. Because the y-intercept (0, -20) is below the x-axis, we know for certain tht the graph intersects the x-axis in two places. Our job is to determine the two horizontal intercepts, which in turn determine the solution set.

x^2 + x - 20 = 0 factors as follows: (x + 5)(x - 4) = 0, whose roots are -5 and 4.

These two roots form 3 intervals: (-infinity, -5), (-5, 4) and (4, infinity). We now must identify on which intervals x^2 + x - 20 is less than 0 (that is, on which intervals the graph is below the x-axis). Choose three test values for x: the first could be -6 (which is in the set (-infinity, -5) ); x^2 + x - 20 is + there, and so the graph is above the x-axis and x^2 + x - 20 is positive. Reject this.

Next, test x = 0; x^2 + x - 20 is negative there, meaning that x^2 + x - 20 < 0 and that x^2 + x < 20. Thus, the solution is (-5, 4). It can be shown that x^2 + x - 20 is positive again for x-values within the interval (4, infinity).

d) first degree binomial
can some one plss help me??

Answers

Answer:

a) third degree trinomial

Step-by-step explanation:

The degree of a polynomial is the same as the degree of the term of the polynomial with the highest degree. The degree of a term is the sum of all the exponents of the variables of the term. Remember that a variable such as x, or y, or z has degree 1.

Now we look at the degree of each term:

2x: degree 1 (since x is the same as x^1)

10x^2: degree 2

-x^3: degree 3

The term with highest degree is the last term which has degree 3, so the degree of the polynomial is 3.

The polynomial has 3 terms, so it is a trinomial.

Answer: a) third degree trinomial

One of the sides of a parallelogram has the length of 5 in. can the lengths of the diagonals be: 4 in and 6 in?
PLEASE PROVIDE AN EXPLANATION

Answers

Answer:

Yes, the diagonals could be 6 and 7 in. In a parallelogram, only the opposite sides of the parallelogram are congruent.

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other, so you can set the labeled segments equal to one another and then solve for . \displaystyle 20 - 3x = 2x - 4 \rightarrow 24 = 5x \rightarrow 4.8 = x. Then, substitute 4.8 for in each labeled segment to get a total of 11.2 for the diagonal length.

A store manager combines 2 lb of trail mix that contains some cashew nuts with 30 lb
of trail mix that is 20% cashews. The result is a trail mix that is 25% cashews. What is the concentration of cashews in the first mixture?

Answers

Answer:

100%

Step-by-step explanation:

Let p = percent of cashews in first mix

2p = lb. of cashews in first mix

30(.20) = 6 = lb. of cashews in second mix

32(.25) = 8 = lb. of cashews in the combined mix

So,

lb. of cashews in first mix + lb. of cashews in second mix = lb. of cashews in the combined mix

2p + 6 = 8

2p = 2

p = 1 = 100%

Answer:

100%
