How do you solve this?

Answer:

28/55

Step-by-step explanation:

The probability of taking a red bead first and a white bead second is:

P(red, white) = (7/11) (4/10)

P(red, white) = 14/55

The probability of taking a white bead first and a red bead second is:

P(white, red) = (4/11) (7/10)

P(white, red) = 14/55

So the probability that one bead of each color is taken is:

P = P(red, white) or P(white, red)

P = 14/55 + 14/55

P = 28/55

Answer:

x = -4

x = 6

Step-by-step explanation:

x² - 2x -24 = 0

x² - 6x + 4x - 24 = 0

x ( x - 6 ) + 4 ( x - 6) = 0

x + 4 and x- 6

so either of them is zero so values if x are

X = -4

X = 6

The Answer is (x+4) (x-6). I just took the test

Answer:

x=0.5

Step-by-step explanation:

6x=4-2x

8x=4

x=1/2

Answer:

0.5

Step-by-step explanation:

You solve it as a 2-step equation.

0.6x=0.4-0.2x

Isolate the variables ((add 0.2x to both sides since that it how you get rid of it at the right))

Your equation should now be

0.8x=0.4

Divide both sides by 0.8 in order to get x by itself

x=0.5

The missing coordinate r is 11.

Solution:

Given points are (–15, 1) and (–7, r).

[tex]x_{1}=-15, x_{2}=-7, y_{1}=1 \text { and } y_{2}=7[/tex]

Slope (m) = [tex]\frac{5}{4}[/tex]

To find the missing coordinate r:

Slope formula:

[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]

Substitute the given values in the formula.

[tex]$\frac{5}{4}=\frac{r-1}{-7-(-15)}[/tex]

[tex]$\frac{5}{4}=\frac{r-1}{-7+15}[/tex]

[tex]$\frac{5}{4}=\frac{r-1}{8}[/tex]

Do cross multiplication.

[tex]8 \times 5=4(r-1)[/tex]

40 = 4r – 4

Add 4 on both side of the equation.

44 = 4r

Divide by 4 on both side of the equation.

11 = r

⇒ r = 11

Hence the missing coordinate r is 11.

Step-by-step explanation:

36-7x=-7(x-5)

first what we have to do is do the multiplications

36 - 7x = -7x + 35

we add 7x from both sides

36 - 7x + 7x = - 7x + 7x + 35

36 = 35

we subtract 36 from both sides

36 - 36 = 35 - 36

0 = -1

This means that the system has no solution

if we look at the equation at the beginning we can realize since we have the same term on both sides "-7x" and a term without x on each side, this means that we can never find a value of x that meets the conditions

Answer:

cos 60° isn't equivalent

Step-by-step explanation:

cos 60°=1/2

The expression that is not equivalent to cos 150° is option C, cos 60 degrees, because it lies in the first quadrant where cosine is positive, unlike cos 150° which is negative.

The expression that is not equivalent to cos 150° is C) cos 60 degrees. The cosine function is positive in the first and fourth quadrants and negative in the second and third quadrants. Since 150° lies in the second quadrant, cos 150° is negative. Now, if we look at the provided options, sin 240° is essentially -sin(240° - 180°), which equals -sin 60°; this is the same as cos(180° - 240°), which equals cos(330°) or cos(−30°), and therefore, equivalent to cos 150°.

Similarly, cos 210° is also in the third quadrant where cosine is negative; this is the same as -cos(210° - 180°), which equals -cos 30° which also equals -sin 60°. Therefore, this is equivalent to cos 150° as well. In contrast, cos 60° lies in the first quadrant where cosine is positive, which does not match the sign of cos 150°. Lastly, -sin 60° is simply the negative of sin 60° and since sin 60° = cos 30°, it matches the value of cos 150° in terms of magnitude but is opposite in sign, thus it is equivalent to cos 150°.

Therefore, option C, cos 60 degrees, is not equivalent to cos 150°.

The equation that I think you are looking for is:

c = 8h + 6

Step-by-step explanation:This is a simple question.

The food that lasts for 48 men for 16 days is 48 × 16 = 768 units.

Now because of 16 additional members i.e. a total of 64 men the food will last for:

768÷64 = 12 days. Answer.

Final answer:

The ration that would have lasted for 16 days for 48 men will now last for 12 days when an additional 16 men are added to the group, making it a total of 64 men.

Explanation:

The question concerns a problem in ration proportion related to the consumption of food by a group of men. Initially, 48 men have enough rations for 16 days. If 16 more men join this group, the total number of men becomes 48 + 16 = 64 men. We need to calculate how long the rations will last for the increased group.

We can consider this as a problem of inverse proportion where more men would consume the same amount of food in lesser time. The original group of 48 men could last 16 days, so we can set up the following proportion: 48 men × 16 days = 64 men × X days. Solving for X gives us X = (48 men × 16 days) / 64 men, which simplifies to X = 12 days. Therefore, the food would last for 12 days for 64 men.

Answer:

The answer is 70 if it's to whole number but if it's just rounding to the tenth spot it's 69.6

Step-by-step explanation:

It's 70 because if the tenth spot(the number after the decimal) is 5 or higher you add one on the one spot so that's why it's 70

Estimates are typically whole numbers.

To estimate an answer, you would take whatever numbers you are trying to add/subtract/multiply/divide ect. and round them to the nearest whole number then complete said action with them.  

Example: 3.99 + 33.85 + 31.74

3.99 is closest to 4

33.85 is closest to 34

and 31.74 is closest to 32

Then, we would add up all the numbers: 4 + 34 + 32 = 70

70 is very close to 69.58, therefore 70 is a good estimate.

Answer:

y = (-1/2)x

Step-by-step explanation:

The slope of the given line is 2, the perpendicular line wil have a reciprocal slope given by -1/2 (add a minus sign, move the slope to the denominator).

So all that's left to calculate is the offset b of a line

y = -1/2 x + b  

such that it passes through (4,-2). Filling in that point gives:

-2 = -1/2*4 + b

so b = 0!

y = -1/2x is the answer

Line perpendicular to  y = 2x - 5 is  y = (-1/2)x.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know perpendicular lines have slopes that are negative reciprocal of each other.

The given line y = 2x - 5, has a slope of 2.

So, the given line will have a slope of (-1/2) passing through point (4,-2).

∴ - 2 = (-1/2)(4) + b.

- 2 = - 2 + b.

b = 0.

∴ y = (-1/2)x is our required line.

Answer:

it could be a isosceles triangle.

Step-by-step explanation:

A right triangle can also be an isosceles triangle.

Final answer:

A right triangle, which always has a 90-degree angle, can be either Scalene if all sides are different lengths, or Isosceles if two sides are equal. The classification depends on the lengths of the sides. Additionally, right triangles are fundamental to the application of the Pythagorean theorem.

Explanation:

A right triangle is a type of triangle that has one angle measuring exactly 90 degrees. Despite always having this right angle, right triangles can vary in the lengths of their other sides and the measures of their other angles. So, a right triangle can also be classified based on its side lengths:

Therefore, the type of right triangle depends on the specific side lengths and can be either Scalene or Isosceles. The understanding of right triangles also extends to concepts such as the Pythagorean theorem, which relates the lengths of the sides of a right triangle, stating that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Answer:

x =-2 or 0

Step-by-step explanation:

Factoring  7x2+3x-34

The first term is,  7x2  its coefficient is  7 .

The middle term is,  +3x  its coefficient is  3 .

The last term, "the constant", is  -34

Step-1 : Multiply the coefficient of the first term by the constant   7 • -34 = -238

Step-2 : Find two factors of  -238  whose sum equals the coefficient of the middle term, which is   3 .

     -238    +    1    =    -237

     -119    +    2    =    -117

     -34    +    7    =    -27

     -17    +    14    =    -3

     -14    +    17    =    3    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -14  and  17

                    7x2 - 14x + 17x - 34

Step-4 : Add up the first 2 terms, pulling out like factors :

                   7x • (x-2)

             Add up the last 2 terms, pulling out common factors :

                   17 • (x-2)

Step-5 : Add up the four terms of step 4 :

                   (7x+17)  •  (x-2)

            Which is the desired factorization

 (x - 2) • (7x + 17)  = 0
