Angles A and B are complementary. Angles A has a measure of (3x+30). Angle B has a measure of 36. What is the value of x?

Answer:

113

Step-by-step explanation:

area of a trapezoid: 1/2 (A+B)h

A is base 1 and B is base 2; h is height

so we have two trapezoids; we just need to add them together

trapezoid 1: ((7+14) x 6)/2

21 x 6 = 126/2 = 63

trapezoid 2: ((10+10) x 5)/2

20 x 5 = 100/2 = 50

50 + 63 = 113

Answer:

centre = (- 5, 7 )

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 5)² + (y - 7)² = 36 ← is in standard form

with h = - 5 and k = 7

centre = (- 5, 7)

The triangle with sides of 10 cm, 8 cm, and 10 cm is categorized as an isosceles triangle as it has two sides of equal length and does not obey the Pythagorean theorem.

The triangle with sides of 10 cm, 8 cm, and 10 cm can be classified as an isosceles triangle. In an isosceles triangle, two sides have the same length, in this case the sides of 10 cm. The third side can be of different length, here given as 8 cm. This triangle is not a right triangle as it does not follow the Pythagorean theorem, where the square of the hypotenuse equals the sum of squares of the other two sides (for right triangles). Thus, based on the given side lengths, the triangle can be confidently classified as isosceles.

The mean weight of the chocolate candies is 0.918 grams, the median weight is 0.913 grams, and the mode (most frequent weights) are 0.957 grams and 0.911 grams.

First, let's add all these values of the weights of the chocolate candies up and then divide by the number of observations to find the mean. The total sum is 13.957, and there are 24 observations. So, the mean value is 13.957/24 = 0.918 grams.

Next, we arrange the values in ascending order to find the median. The middle two values in this data set are both 0.913, so the median is 0.913 grams.

Finally, to find the mode we look for the value that occurs most frequently in the data set. Here we see that the numbers 0.957 and 0.911 both appear twice, therefore, our data set has two modes: 0.957 and 0.911 grams.

The only zero of the function f(x) = x^2 - 8x + 16 is x = 4.

The zeros of a function, f(x), represent the values of x that make the function equal to zero. To find the zeros of the given function, f(x) = x^2 - 8x + 16, we need to solve the equation f(x) = 0.

Let's set the equation equal to zero and solve for x:

x^2 - 8x + 16 = 0

To solve this quadratic equation, we can use factoring or the quadratic formula. In this case, the equation can be factored as:

(x - 4)(x - 4) = 0

This means that the equation is equivalent to (x - 4)^2 = 0.

To find the zeros, we set (x - 4)^2 = 0 and solve for x:

(x - 4) = 0

x = 4

So, the only zero of the function f(x) = x^2 - 8x + 16 is x = 4.

In other words, the graph of the function f(x) = x^2 - 8x + 16 intersects the x-axis at the point (4, 0).

Answer:

1/4

Step-by-step explanation:

So, we can create this representation of a in relation with b, since we know a is smaller than b by 1/5 of b, we can say that a is equal to 4/5 of b, right?

[tex]a = \frac{4}{5} b[/tex]

To invert the ratio, we need to isolate B, so we multiply both sides of the equation by 5/4

[tex]a * \frac{5}{4} = * \frac{5}{4} * \frac{4}{5} b = b\\ \\ b = \frac{5}{4} a[/tex]

So, we have b being 1/4 bigger than a.

Answer:

x = -8(y - 5)² + 3

Step-by-step explanation:

When info about focus and directrix is given, we want to use the standard equation of a parabola x - h = 4p(y - k)^2.  

p is the signed distance between focus and vertex (or that between directrix and vertex).  Here the directrix, x = 7, lies to the right of the vertex, (3, 5), which indicates that this horizontal parabola opens to the left.  The total vertex to directrix distance is 7 - 3, or 4; dividing this result by 2 results in 2; thus p = -2 (a signed distance).  

Now we substitute the given and calculated info into the equation

x - h = 4p(y - k)^2:

x - 3 = 4(-2)(y - 5)², or

x - 3 = -8(y - 5)², or x = -8(y - 5)² + 3

Answer:

[tex](y-5)^2=8(x-5)[/tex]

Step-by-step explanation:

We are given that the focus of a parabola is (3, 5) and the directrix is x = 7.

The y-coordinate of the vertex should be same as the focus (k = 5). So the x-coordinate of the vertex would be:

p + (3) =  7 - p

2p = 7 - 3

p = 4/4

p = 2

The x-coordinate of the vertex would be:

h= p + (3)

h = 2 + 3

h = 5

The vertex coordinate would be: (h, k) = (5, 5)

For a vertex (h, k), the formula for equation would be  

[tex](y-k)^2=4 p(x-h)[/tex]

[tex](y-5)^2=4 \times 2(x-5)[/tex]

[tex](y-5)^2=8(x-5)[/tex]

Answer:

Step-by-step explanation:

(I assume it's [tex]12sin^2 x -13 sinx +3 = 0[/tex])

Start by setting [tex] sinx = y [/tex] (or whichever letter you prefer). Your equation becomes [tex] 12y^2 -13y +3 = 0[/tex] . Solving for y you get [tex]y = \frac {-(-13) \pm \sqrt{13^2 - 4*3*12} } {2*12} =\frac{ 13 \pm \sqrt{13^2-12^2}} {24} = \frac {13 \pm5 }{24}\\ y = \frac {18} {24} = \frac 34; y= \frac 8 {24} = 1/3[/tex]

But we're not done yet. Since we said  [tex] sinx = y [/tex], you need to solve both  [tex] sinx = \frac 3 4 [/tex] and  [tex] sinx = \frac 1 3 [/tex], whose solutions are the inverse sine of said values, plus any number of complete rotations.

To find the value of X;

We multiply both sides by 4

1/4 x × 4 = 5/8 × 4

 x = 5/2 or 2.5

To solve the problem we must know about fractions.

A fraction is a way to describe a part of a whole. such as the fraction [tex]\dfrac{1}{4}[/tex] can be described as 0.25

The value of x is [tex]\bold{\dfrac{5}{2}}[/tex] or 2.5.

Given to us,

To remove the denominator from the x side, we multiply both sides of the equation with the denominator of x.

[tex]{\dfrac{1}{4}\times x \times 4\ =\ \dfrac{5}{8} \times 4}[/tex]

Canceling the values we get,

[tex]1 \times x = \dfrac{5}{2}[/tex]

[tex]x = \dfrac{5}{2}[/tex]

Thus, the value of x is  [tex]\bold{\dfrac{5}{2}}[/tex] ,further we can simplify by dividing 5 by 2 and we will get 2.5 as the result.

Hence, the value of x is [tex]\bold{\dfrac{5}{2}}[/tex] or 2.5.

Answer:  387.93 units

Step-by-step explanation:

You have the following information given in the problem above:

- The sales  had dropped 33% from one quarter to the next.

- The owner sold 579 units in the first quarter.

Thefore, to calculate the number of units she sold in the next quarter (which you can call x), you must can apply the following proccedure:

[tex]x=579units-(0.33)(579units)[/tex]

Then the answer is the following:

[tex]x=387.93units[/tex]

To determine the number of units sold in the next quarter, we subtract 33% of 579 (approximately 191) from 579. This results in approximately 388 units sold in the next quarter.

To solve this question, we calculate 33% of the units sold in the first quarter. 33% of 579 equals to 191.07. However, since we cannot have a fraction of a unit, we can approximate this to 191 units. Thus, in the next quarter, the music store owner sold 579 - 191 or 388 units.

This example uses a concept called percentage decrease in mathematics. A percentage decrease is the amount by which a quantity is reduced by a specified percentage.

A percentage is a way of expressing a number as a fraction of 100. It is often denoted using the percent sign, "%". In this case, a decrease in CD sales was represented as a percentage.

Answer:

The answers are that x = 8 and y = 7%

Step-by-step explanation:

To find the value of x, we need to divide 1.36 by the percentage it is of the whole (17%).

1.36/17% = 8

And now to find y, we divide 1.05 by 15

1.05/15 = 7%

Final answer:

The solutions for the percent problems presented by the student are x = 8 for the first equation, and y = 7% for the second equation.

Explanation:

The student presented two separate percent problems. To solve the first one, we need to find the value of x for which 1.36 is 17% of x. We can set up an equation using the percent formula:

Part = Percent × Whole

This gives us:

1.36 = 0.17 × x

By dividing both sides of the equation by 0.17, we get:

x = 1.36 / 0.17

x = 8

For the second problem, where 1.05 is y% of 15, we similarly set up the percent equation:

1.05 = (y/100) × 15

By dividing both sides of the equation by 15, we get:

y = (1.05 / 15) × 100

y = 7

Therefore, the solutions are x = 8 and y = 7%.

Hope this helps! :)

Step-by-step explanation:

so, we know A and B left at the same time, one from city A and the other from city B, they're both moving towards each other, and they met in 5hrs.

now, by the time they met, car A has been running for 5hrs already,

and car B has also been running for 5hrs, so the time for both is the same, when they met, each had been running for 5hrs

if B has a speed rate of "r", then A's speed rate is " r - 10"

now, the next to last paragraph

"If the first automobile had left city A 4 1/2 hours earlier than the other automobile left city B, then the two would have met 150 km away from B."

IF, a big if, but they didn't, they left at the same exact time, so that's just an IF

if A had left 4 1/2 hrs earlier, they'd had met 150km from B

so... by the time A had been running already for 4.5 hrs, car B starts off, goes off and they meet 5hrs later, when they meet, car A would have been running for 5hrs, 4.5 + .5 hrs, but car B would had been running for only half an hour when they met

that means car B met car A half an hour later from when it started, and met A 150kms away from its starting point

that means car B can cover 150km in just half an hour

that gives us a speed rate of 150/.5  

which is 300kmh

now, if car B is 300kmh, car A has r-10, or 300-10, or 290kmh

so, car A's rate is really just 290

now, let's say the total distance is AB

so, by the time car A had been running for 5hrs, it had covered a distance of "d"

by the time car B had been running for 5hrs, it had then covered the slack, or " AB - d "

Final answer:

To construct a parallel line through a point not on the given line, it is essential to know how to construct corresponding angles, which are equal for parallel lines created by a transversal.

Explanation:

To construct a line parallel to a given line m through a point not on line m, you need to know how to construct corresponding angles which are equal when lines are parallel. This process typically involves using a compass and straightedge to replicate the angle between the given line and a transversal at the point not on line m.

First, you would create a transversal through the point not on line m. Then you would measure the angle that the transversal makes with line m. Using the compass, you would reproduce this angle on the transversal at the point not on line m, ensuring that the angles corresponding to each other across the two lines are equal. This ensures that the new line you're constructing is indeed parallel to line m.
