Answer:

x is equal to 12, y is equal to 12√2, or approximately 16.97

Step-by-step explanation:

This can be done in multiple ways, but the easiest is to realise that we are given two angle, which allows us to calculate the third.

Because the bottom left corner is 90 degrees, and the bottom right is 45 degrees, that means that the top angle is also 45 degrees.  We can say this because we know that the sum of the angles inside a triangle must add up to 180 degrees.

Because those two angles are the same, we know that this is not only a right triangle, but also an isosceles triangle, with two lengths of the same size. In this case then the bottom side, x is equal to the left side: 12m.

From that we can work out y, the hypotenuse of the triangle, using the Pythagorean theorem:

[tex]y = \sqrt{12^2 + 12 ^2} \\y = \sqrt{144 + 144}\\y = \sqrt{288}\\y= 12\sqrt{2}\\[/tex]

So y, the length of the hypotenuse is equal to 12√2, or approximately 16.97

Answer:339.29

Step-by-step explanation:

The closest surface area of the container in square inches is 339.29 square inches.

The correct option is B.

A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.

Given:

An architect uses a cylindrical container to protect her blueprints.

The dimensions of the cylinder shown in the diagram.

The surface area of the cylinder,

= 2πrh + 2πr²

= 2 (3.14) (3)(15) + 2 (3.14) (9)

= 339.12 square inches.

Therefore, the surface area is 339.12 square inches.

Answer:

Jasmine ate [tex]\frac{3}{12}[/tex] of the pizza.

Step-by-step explanation:

So the problem tells us that Jasmine cut her pizza in 12 slices while Kelly cut it only in 6 slices (see first part of the attached image)

out of the 6 slices, Kelly ate 2 slices. This represents 2/6 of the pizza. So we shade two of the 6 slices of Kelly's pizza. (See second part of the attached image).

Now for us to be able to compare the two pizzas we need to find a way for all the slices to be the same (find the Least Common Denominator). We know that 6 fits into 12 two times, so we can split each of Kelly's slices in half, so now we will have 12 slices. This means that the amount of piza Kelly ate represents:

[tex]\frac{2}{6}*\frac{2}{2}=\frac{4}{12}[/tex] of a pizza.

The problem tells us that Jasmine and Kelly together ate [tex]\frac{7}{12}[/tex] of a pizza. We know Kelly ate the equivalent to 4 slices the same size of those of Jasmine. So This means that Jasmine must have eaten 7-4=3 slices. So together they ate the equivalent to:

[tex]\frac{3}{12}+\frac{4}{12}=\frac{7}{12}[/tex] of a pizza.

therefore Jasmine ate [tex]\frac{3}{12}[/tex] of a pizza.

Answer:

infinite many solutions

Step-by-step explanation:

Answer:

Solving the equation : [tex]y+\frac{y}{a}=b\:if\:a\neq\: -1[/tex]  for y we get [tex]\mathbf{y= \frac{ab}{a+1},\:if\:a\neq -1}[/tex]

Step-by-step explanation:

We need to solve for y the equation: [tex]y+\frac{y}{a}=b\:if\:a\neq\: -1[/tex]

We need to find value of y

Solving:

[tex]y+\frac{y}{a}=b[/tex]

Taking LCM of a, 1 we get a

[tex]\frac{a*y+y}{a}=b\\\frac{ay+y}{a}=b[/tex]

Multiply both sides by a, a will be cancelled on left side

[tex]a(\frac{ay+y}{a})=ab\\ay+y=ab[/tex]

Taking y common from left side:

[tex]y(a+1)=ab[/tex]

Divide both sides by a+1

[tex]\frac{y(a+1)}{a+1}=\frac{ab}{a+1}\\y= \frac{ab}{a+1},\:if\:a\neq -1[/tex]

So, Solving the equation : [tex]y+\frac{y}{a}=b\:if\:a\neq\: -1[/tex]  for y we get [tex]\mathbf{y= \frac{ab}{a+1},\:if\:a\neq -1}[/tex]

Step-by-step explanation:

Ight so 60/12 is 5. So then you'd multiply 100 by 5 to get 500, therefore she is moving 500 yards per minute.

Then you'd obviously just convert that to feet which is 1500 feet.

Answer:

B   x = sqrt(41)

Step-by-step explanation:

Since the large triangle is isosceles, the smaller triangles on the right side and left side are congruent right triangles.

The base of each smaller right triangle is 4 units long (8/2 = 4).

The vertical leg is 5.

Use the Pythagorean theorem to find x.

a^2 + b^2 = c^2

4^2 + 5^2 = x^2

16 + 25 = x^2

x^2 = 41

x = sqrt(41)

Answer: B   x = sqrt(41)

Answer

B

Explanation

To find the value of x, you need to use the Pythagorean theorem.

[tex]x^{2} + y^{2} = z^{2}[/tex]

x is one of the legs.

y is another one of the legs.

z is the hypotenuse (the longest side of a right triangle).

Now for this we can set 5 to be x and 4 to be y.

y is 4 because 4 is half of 8. We need to find half of 8 because the right triangle is half of the whole triangle.

Now 'plug' these into the formula and find z.

[tex]5^{2} + 4^{2} = 41^{2}[/tex]

To find z then we must find the square root of 41.

So the answer is B.

(Now I just realized that I used the variable z for the hypotenuse when you were supposed to be finding x for the hypotenuse but whatever).

A. because you use the coeficients of the equation

8*x³ +1*x² +0*x -5 and 6

The division problem in the synthetic division is:

  6 | 8   1   0  -5

Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.

To perform synthetic division, we need to set up the problem with the divisor x - 6 as follows:

  6 | 8   1   0  -5

    |___   __   ____

    |     48  294 1764

    |________________

     8  49  294 1759

Therefore, the quotient is 8x² + 49x + 294 with a remainder of 1759/(x-6). The final answer in synthetic division form is:

8x³ + x² - 5 = (x-6)(8x² + 49x + 294) + 1759/(x-6)

Incomplete question. The full question read;

The producer of the news station posted an article about the high school’s football championship ceremony on a new website. The website had 500 views after four hours. Create a table to show how many views the website would have had after the first, second, and third hours after posting if the website receives views at the same rate. How many views would the website receive after 5 hours?

Answer:

625 views

Step-by-step explanation:

Remember, we are told to base our calculation on the assumption that the website receives views at the same rate.

Hence, if after 4 hours there were 500 views, it means the average views per hour would be 500/4 = 125 views. So for every hour, there would be 125 added views to the total.

In other words,

First hour: 125 views

Second hour: 250 views (125 views + 125 views)

Third hour: 375 views (250 views + 125 views)

Fourth hour: 500 views (375 views + 125 views)

Fifth hour: 625 views (500 views + 125 views)

Answer:

Step-by-step explanation:

Given that Points A, B, and C are collinear.

AB = 2x-1

BC= 3x +11

AC = 125

Point B is between A and C.

so

AC = AB + BC

substituting the values

125 = 2x-11 + 3x+11

125 + 11 = 2x+3x+11

136 = 5x+11

136-11 = 5x

125 = 5x

x = 25
