10x+50+80=180

Answers

Answer:

x= 5

Step-by-step explanation:

10(5)+50+80=180

Multiply the 5 by 10

10*5=50

50+50+80=180

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x=5

Step-by-step explanation:

10x+50+80=180

combine 10x(50+80)=180, 10x+130=180

subtract 10x(130-130)=(180-130), 10x=50

divide 10 by 50 to find x=5

Third answer option

{(1,2), (-2, 2), (-2, 4), (-4,4)}

Step-by-step explanation:

If the Domain is the set = { -4, -2, 1}, we need a relationship that shows pairs with first coordinates as described below:

(-4, ...) , (-2, ...) and (1, ...)

There are 7 times as many dogs as cats. If the total number of dogs and cats is 32, how many dogs are there?

Answers

Hey there! I don’t know if I am correct but let me try to help.

We know that there are 7 times as many dogs as there are cats. So, if there are 4 cats, we know that 4 x 7=28. So, there would be 28 dogs. And 28+4=32.

Choice B.   [-5, -4]

Choice D.  [1, 2]

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

Explanation:

We're looking for portions when the graph goes downhill when we move from left to right.

The first portion is from x = -5 to x = -4. So we write [-5, -4] which represents [tex]-5 \le x \le -4[/tex]

The second portion is [1, 2] which goes downhill since the interval starts at x = 1 and stops at x = 2.

The portions are highlighted in the diagram below.

As you can see, we only care about the x values for any given interval. The y values don't matter as long as they decrease along the interval.

Answer:

Options A, C & E

Step-by-step explanation:

For the probability of an event E which is denoted by: P(E).

In complementary events, the complement of E is denoted by: P(E').

Now, the complement means the outcome that Event E does not occur.

This means that the sample space is 1.

Thus;

P(E) + P(E') = 1

It can be rewritten as;

P(E') = 1 - P(E)

It can also be written as;

P(E) = 1 - P(E')

The correct options are; A, C & E

A classroom of children has 17 boys and 19 girls in which five students are chosen to do presentations. In how many ways can the five students be chosen so that more boys than girls are selected

Answers

Answer:

167688 ways

Step-by-step explanation:

Given that:

Number of boys = 17 &;

Number of girls = 19

The number of ways that five students can be chosen such that more boys than girls are selected are:

The ways of choosing = 5 boys 0 girls + 4 boys 1 girl + 3 boys 2 girls

The ways of choosing = [tex]^{17}C_5 +( ^{17}C_4 \times ^{19}C_1} )+( ^{17}C_3 + ^{19}C_2})[/tex]

The ways of choosing = [tex]\dfrac{17!}{5!(17-5)!} + \begin {pmatrix} \dfrac{17!}{4!(17-4)!} \times \dfrac{19!}{1!(19-1)!} \end {pmatrix} + \begin {pmatrix} \dfrac{17!}{3!(17-3)!} \times \dfrac{19!}{2!(19-2)!} \end {pmatrix}[/tex]

[tex]=\dfrac{17!}{5!(12)!} + \begin {pmatrix} \dfrac{17!}{4!(13)!} \times \dfrac{19!}{1!(18)!} \end {pmatrix} + \begin {pmatrix} \dfrac{17!}{3!(14)!} \times \dfrac{19!}{2!(17)!} \end {pmatrix}[/tex]

[tex]=\dfrac{17*16*15*14*13*12!}{5!(12)!} + ( \dfrac{17*16*15*14*13!}{4!(13)!} \times \dfrac{19*18!}{1!(18)!} ) + ( \dfrac{17*16*15*14!}{3!(14)!} \times \dfrac{19*18*17!}{2!(17)!} )[/tex][tex]=6188 + ( 2380\times19 ) + (680 \times171)[/tex]

= 167688 ways

Using the combination principle, the number of ways of selecting 5 students such that the number of boys is greater the number of girls selected ls 167688 ways.

Number of boys = 17

Number of girls = 19

Number of selections to be made = 5

In other to choose more boys than girls :

5 boys and 0 girls4 boys and 1 girl3 boys and 2 girls

Using the combination relation :

(17C5 × 19C0) + (17C4 × 19C1) + (17C3 × 19C2)

(6188 × 1) + (2380 × 19) + (680 × 171)

(6188 + 45220 + 116280)

= 167688 ways

Therefore, the Number of ways of making the selection is 167688 ways

Let sin(2x) = cos(x), where 0° ≤ x < 180°. What are the possible values for x?

30° only
90° only
30° or 150°
30°, 90°, or 150°

Answers

Double angle identity for sine:

sin(2x) = 2 sin(x) cos(x)

So rewrite the equation as

sin(2x) = cos(x)

2 sin(x) cos(x) = cos(x)

2 sin(x) cos(x) - cos(x) = 0

cos(x) (2 sin(x) - 1) = 0

There are two cases,

cos(x) = 0   or   2 sin(x) - 1 = 0

cos(x) = 0   or   sin(x) = 1/2

In the interval 0º ≤ x < 180º, we have cos(90º) = 0 and sin(30º) = sin(150º) = 1/2, so the possible values are 30º, 90º, or 150º.

Evaluate the line integral, where C is the given curve. (x 6y) dx x2 dy, C C consists of line segments from (0, 0) to (6, 1) and from (6, 1) to (7, 0)

Answers

Answer:

[tex]\mathbf{\int _c (x+6y)\ dx + x^2 \ dy = \dfrac{91}{6}}[/tex]

Step-by-step explanation:

The integral of the curve is given as:

[tex]\int (x +6y) \ dx +x^2 \ dy[/tex]

Where the line segment from (0,0) to (6,1) is:

0 < x < 6 and [tex]y = \dfrac{x}{6} \implies dy = \dfrac{dx}{6}[/tex]

Thus;

[tex]\int ^{6,1}_{0,0} (x+ 6 * \dfrac{x}{6}) \ dx + \dfrac{x^2*dx}{6 } = \int^6_0 (x+x+\dfrac{x^2}{6}) \ dx[/tex]

[tex]\int^6_0 (x+x+\dfrac{x^2}{6}) \ dx = \int^6_0 (2x +\dfrac{x^2}{6}) \ dx[/tex]

[tex]\int^6_0 (x+x+\dfrac{x^2}{6}) \ dx = \begin {bmatrix} \dfrac{2x^2}{2}+\dfrac{x^3}{18} \end {bmatrix}^6_0[/tex]

[tex]\int^6_0 (x+x+\dfrac{x^2}{6}) \ dx = \begin {bmatrix} x^2+\dfrac{x^3}{18} \end {bmatrix}^6_0[/tex]

[tex]\int^6_0 (x+x+\dfrac{x^2}{6}) \ dx = \begin {bmatrix} (6)^2+\dfrac{(6)^3}{18} \end {bmatrix}[/tex]

[tex]\int^6_0 (x+x+\dfrac{x^2}{6}) \ dx = \begin {bmatrix} 36+12 \end {bmatrix}[/tex]

[tex]\int^6_0 (x+x+\dfrac{x^2}{6}) \ dx =48 --- (1)[/tex]

Similarly; at (6,1) to (7,0)

[tex]\implies 6 \leq x \leq 7 \ and \ y = -x +7[/tex]

Thus; the integral can be computed as :

[tex]\int ^{(7,0)}_{(6,1)} \ (x+6(-x+7)) \ dx + x^2 (-dx) = \int^7_6 (-5x +42 -x^2) \ dx[/tex]

[tex]\int^7_6 (-5x +42 -x^2) \ dx= \begin {bmatrix}- \dfrac{5x^2}{2}+ 42x -\dfrac{x^3}{3} \end {bmatrix}^7_6[/tex]

[tex]\int^7_6 (-5x +42 -x^2) \ dx= \begin {bmatrix}- \dfrac{5(7^2-6^2)}{2}+ 42(7-6) -\dfrac{(7^3-6^3)}{3} \end {bmatrix}[/tex]

[tex]\int^7_6 (-5x +42 -x^2) \ dx= \begin {bmatrix}- \dfrac{5(49-36)}{2}+ 42(1) -\dfrac{(343-216)}{3} \end {bmatrix}[/tex]

[tex]\int^7_6 (-5x +42 -x^2) \ dx= \begin {bmatrix}- \dfrac{5(13)}{2}+ 42 -\dfrac{(127)}{3} \end {bmatrix}[/tex]

[tex]\int^7_6 (-5x +42 -x^2) \ dx= \begin {bmatrix}- \dfrac{-195+252-254}{6}\end {bmatrix}[/tex]

[tex]\int^7_6 (-5x +42 -x^2) \ dx= - \dfrac{-197}{6} --- (2)[/tex]

By adding (1) and (2) ; we have:

[tex]\int _c (x+6y)\ dx + x^2 \ dy = 48 + (-\dfrac{197}{6})[/tex]

[tex]\int _c (x+6y)\ dx + x^2 \ dy = (\dfrac{288-197}{6})[/tex]

[tex]\mathbf{\int _c (x+6y)\ dx + x^2 \ dy = \dfrac{91}{6}}[/tex]

Answer:

The slope of the line is 2/5

Step-by-step explanation:

Start counting where the y-intercept is. The y-intercept is at (0,1). The line is positive since it is increasing from left to right, so you need to count up and then to the right in order to find the slope. You need to find a point where the line intercepts a coordinate point directly on the line. If you look at the point (5,3) it is directly on the intersection that runs up and down. Start at 1 and count 2 up and 5 to the right. You will end up on the point (5,3). Hope this helps. Ask more questions if you need to
