If 1ml of water fills 1 cubic centimeter of space, how many ml of water are needed to fill each tank?

Answer:

The area of the shape is 49.

Step-by-step explanation:

The shape is a trapizoid, so we use the formula: I've attached an image below.

H stands for height, the height is 7.  b1 is 3 (the first base length) and b2 is 11 (the second base length.)

Now, we plug it into the formula.

A=1/2(7)(3+11)

A= 49.

Hope this helps. :)

Step-by-step explanation:

Answer:

This graph is not a function

Step-by-step explanation:

The input x is used more than once

it is not a parabola

Answer:

X can either be -4 or 11.

Step-by-step explanation:

[tex]x^{2} - 7x - 34 = 10\\\\Make this into a quadratic equation:\\\\x^{2} - 7x - 44 = 0\\ \\Find the factor pairs of -44 and their sums:\\-1,44 sum is 43\\ -2,22 sum is 20\\-4,11 sum is 7\\1, 44 sum is 45\\2, -22 sum is 20\\4, -11 sum is -7\\\\\\Find a sum that is equal to the coefficient of x which is -7 in this case. As we can see the pair 4, -11 corresponds to a sum of -7, therefore we can use this to factorise this quadratic equation and get two solutions:\\\\(x + 4) (x - 11) = 0\\[/tex]

If we set (x+4) to zero then x equals -4

If we set (x-11) to zero then x equals to 11.

So x can be -4 or 11.

[tex]\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}[/tex]

              x<-4

[tex]\blue{\textsf{\textbf{\underline{\underline{How\:to\:Solve:-}}}}[/tex]

                      First, add 6x on both sides:

-2x+3+6x<-13

Add the x's:

4x+3<-13

Now, subtract 3 on both sides:

4x<-13-3

4x<-16

Divide by 4 on both sides:

x<-4

So the values of x that are less than -4 will make the given inequality true.

Answer:

The two factors of the first number are -4 and 9.

Step-by-step explanation:

We're given:

Let the two numbers be a and b:

Isolate a in the second equation and solve for b:

[tex]a+b=5\\a=5-b[/tex]

[tex](5-b)b=-36\\5b-b^2=-36[/tex]

Arrange in [tex]ax^2+bx+c=0[/tex] format:

[tex]-b^2+5b+36=0[/tex]

Divide both sides by -1:

[tex]b^2-5b-36=0[/tex]

Factor:

[tex]b^2+4b-9b-36=0\\b(b+4)-9(b-4)=0\\(b-9)(b+4)=0[/tex]

Solve for b using the zero product property:

[tex]b=-4,9[/tex]

Substitute b back into the second equation to solve for a:

[tex]a+b=5[/tex]

First, let b = -4:

[tex]a-4=5\\a=9[/tex]

Let b = 9:

[tex]a+9=5\\a=-4[/tex]

Answer:

∠b = 53°

Explanation:

Complimentary angles are when two angles sum up to 90°

Here given:

∠a : 37°

∠b : missing angle

These angles sum up to 90 degree:

x + 37 = 90°

x = 90° - 37°

x = 53°

Answer:

therefore 1. 100 square feet and 2. 270 square feet

Step-by-step explanation:

1. Area for trapezium is (a+b)/2 times height

[tex]\frac{a + b}{2} *h\\[/tex]

[tex]\frac{9 + 16}{2} * 8[/tex]

= 100

2. Area for kite is ab/2 where a and be are the perpendicular diagonals:

[tex]\frac{ab}{2}[/tex]

[tex]\frac{10 * 54}{2} = 270[/tex]

That is the differnce between the 2 numbers and it is in a negative because the second number was bigger than the first number so if you don't need the negative don't put it in your answer

-56.22 is the difference between 25 and  [tex]81\frac{2}{9}[/tex]

A fraction represents a part of a whole.

A proper fraction has a numerator that is less than its denominator .

An improper fraction has a numerator greater than its denominator.

An improper fraction is always greater than one whole.

We need to find the difference between 25 and of [tex]81\frac{2}{9}[/tex]

Difference is nothing but subtraction. We need to subtract  [tex]81\frac{2}{9}[/tex] from 25

25 - [tex]81\frac{2}{9}[/tex]

25-731/9

25×9-731/9

225-731/9

-506/9

=-56.22

Hence -56.22 is the difference between 25 and  [tex]81\frac{2}{9}[/tex]

Answer:

  (c)  68 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  50° +62° +x = 180°

  x = 68° . . . . . . . . . . subtract 112° from both sides

The​ line-of-sight distance from the television camera to the base of the stadium​ is 1918.16 meters

A right triangle has one of its angles as 90 degrees.

Therefore, the angles and side can be found using trigonometric ratios.

Hence, the​ line-of-sight distance from the television camera to the base of the stadium​ is hypotenuse side of the right triangle formed.

sin 9° = opposite / hypotenuse

sin 9° = 300 / h

h = 300 / sin 9

h = 300 / 0.15643446504

h = 1918.15856777

h = 1918.16 meters

Remark

If you learn how to do this, a part of science called dimensional analysis will  come more easily to you. It looks like this.

7 yds [3 ft/yd] [12 in / ft] = 252 inches.

Notice how it works. In the first set of brackets, the yards cancel. You have 21 feet. In the second set of brackets, the feet cancel, and you are left with inches.

Proportions

If this does not appeal to you, you can do it the standard way.

1 yard / 3 feet = 7 yards / x (feet)               Cross Multiply

1 yard * x = 7 yards * 3 feet.                        Divide by yards

1 yard * x / yard = 7 yards * 3 feet/yds       The yards cancel

x = 21 feet

1 foot / 12 inches = 21 feet / x                     Cross Multiply

1 foot * x = 12 inches * 21 feet                     Divide by ft

1 foot *x / foot = 12 inches *21 ft/ft            

x = 252  inches

= 14n - 22

Answer:

The measure of angle 1 is 71° ⇒ c

Step-by-step explanation:

Look to the attached figure:

∵ Line l intersect line n

∴ Angle 63° and angle (15x - 3) are linear pair

- The sum of the linear pair angles is 180°

∵ 63° + (15x - 3)° = 180°

- Add like terms

∴ 60 + 15x = 180

- Subtract 60 from both sides

∴ 15x = 120

- Divide both sides by 15

∴ x = 8

∵ Line m intersect line n

∴ Angle (8x + 7) and angle 1 are vertical opposite angles

- The vertical opposite angles are equal in measure

∴ m∠1 = 8x + 7

∵ x = 8

- Substitute the value of x to find m∠1

∴ m∠1 = 8(8) + 7

∴ m∠1 = 64 + 7

∴ m∠1 = 71

The measure of angle 1 is 71°

Choice A

Choice D

Choice E

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

Explanation:

The list of perfect squares is:

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, ...

If we apply the square root to any of those numbers, then the number is rational.

For example, [tex]\sqrt{25} = 5 = \frac{5}{1}[/tex]

A rational number is any fraction of two integers, where zero is not in the denominator.

Based on this, we can see that choice A represents a rational number because we are summing rational numbers.

More specific proof is to write [tex]\sqrt{4} + \sqrt{16} = 2 + 4 = 6 = \frac{6}{1}[/tex] showing it is rational.

---------------------

Choice B is ruled out because [tex]\sqrt{5}[/tex] is irrational. We cannot write it as a fraction of two integers.

Choice C is ruled out for similar reasoning as choice B. This time [tex]\sqrt{24}[/tex] is irrational.

----------------------

Choice D is another answer because [tex]2*\sqrt{4} = 2*2 = 4 = \frac{4}{1}[/tex] is rational.

Choice E is another answer as well because [tex]\sqrt{49}*\sqrt{81} = 7*9 = 63 = \frac{63}{1}[/tex] is rational.

Choice F is ruled out because [tex]\sqrt{12}[/tex] is irrational, which in turn makes [tex]3\sqrt{12}[/tex] irrational as well.
