Answer:

<h3>            These numbers are 3 and 9</h3>

Step-by-step explanation:

x - smaller number

3x - three times the smaller number = the larger number

2×3x - twice the targer number

2×3x+3x  - twice the larger is added to three times the smaller

2×3x + 3x = 27

6x + 3x = 27

  9x = 27

 ÷9     ÷9

   x = 3

3x = 3×3 = 9

In a circle whose center is O, arc AB contains 100. Find the number of degrees in angle ABO. WILL MARK BRAINLIEST FOR BEST ANSWE
marusya05 [52]

Answer:

It is so easy u should get this right.

First draw a circle and there is an arc that is like forming a triangle inside a circle and then ab angle is 100 degree and outside is the center of the circle. And since u try to find how much is outside it most likely means that 100-60=40

so it b 40.

Please help &lt;3 Find the value of the variables in the parallelograms.
Mashutka [201]

Answer:

Hello!

answer: a = 5

b = 8

Step-by-step explanation:

since we are given 1 side of the parellogram we can use that to figure out the rest! parellograms will add up to 360 degrees since 1 angle is 115 that means the other will be 115 115 + 115 = 230

360 - 230 = 130 since there 2 angles across from each other they will both equal the same so 130 ÷ 2 = 65 so both of these angles will have to equal 65 because 65 + 65 + 115 + 115 = 360 a = 5 because 14 x 5 = 70 and 70 - 5 = 65 b = 8 because 8 x 8 = 64 and 64 + 1 = 65 Hope this helps you understand!

A fish tank is filled with water.The tank holds 150 gallons.Each cubic foot of water contains about 7.5 gallons.The rank is 5 fe
san4es73 [151]

Answer:

Width = 1\frac{1}{3} ft

Step-by-step explanation:

The tank holds 150 gallons of water.

7.5 gallons holds 1 ft³ of water.

So 150 gallons will hold;

\frac{150}{7.5} × 1 ft³ = 20 ft³

The volume of the tank = Length(l) × Width(w) × Height(h) = 20 ft³

i.e 5 ft × w × 3 ft = 20 ft³

15w ft² = 20 ft³

w = \frac{20 ft^3}{15 ft^2} =  1\frac{1}{3} ft

Find AB. Round the answer to the nearest tenth if needed.
Yuliya22 [10]

9514 1404 393

Answer:

  8

Step-by-step explanation:

The product of segment lengths to the near and far circle intersection points is the same for both "secants". AD is a tangent, so the two intersection points are the same point. This gives ...

  AD² = AB·AC

  144 = AB(AB +10)

We can add 25 to complete the square.

  169 = (AB +5)² . . . write as a square

  13 = AB +5 . . . . . . positive square root

  8 = AB . . . . . . . . . .subtract 5

Short Answer: C
Remark

The first thing you really ought to do is get a graph from one of the graphing programs on the internet. Most of the time, I use Desmos. That will give you the answer. I will put the graph at the bottom of the page.

The second thing you could do is just set up the given points to see which one gives you the answer.

The third thing (and I'll do this one) is to actually solve the problem by completing the square.

Givens
a = -2
b = 6
c = -1

Solution
Put brackets around the first two terms.
y = (- 2x^2 + 6x ) - 1                               Take out the common factor of - 2
y = -2(x^2 - 3x ) - 1                                 Complete the square inside the brackets.

y = -2(x^2 - 3x + (3/2)^2 ) - 1                  Add what it took to complete the square after the - 1

y = -2(x^2 - 3x + (3/2)^2 ) - 1 + 2(3/2)^2 * See remark at end to see why its +
y = -2(x^2 - 3x + 9/4) - 1 + 2 * (9/4)
y = -2(x^2 - 3x + 9/4) - 1 + 18/4
y = -2(x^2 - 3x + 9/4) + 14/4         Show the brackets in square form.
y = -2(x - 3/2)^2 + 14/4  but 3/2 =1.5 and 14/4 = 3.5
y = -2(x - 1.5)^2 + 3.5

The axis of symmetry is x = 1.5  The vertex is (1.5, 3.5)

Discussion
You may wonder why you are adding 18/4 outside the brackets when you are completing the square and all you have inside the brackets is 9/4.

The reason is because first of all there is a - 2 outside the brackets. That gets you 18/4. Because you have got a minus 2, you have to compensate the result so that you get 0. The only way to do that is to add 18/4.
