Answer:

x = 12

Step-by-step explanation:

Using the formula (which is a geometric mean):

a       y

---- = -----

x       a

Where a is the altitude (6), x is a projection (x), and y is the other projection (3):

6       3

---- = -----

x       6

Cross multiply:

36 = 3x

12 = x

x = 12

Answer:

Change 28% to a decimal by moving the decimal point 2 places to the left:

28% = 0.28

Write the question as an equation to get:

56 = 0.28x

Now to solve for x, divide both sides by 0.28:

x = 56 / 0.28

x = 200

The unknown number is 200.

Step-by-step explanation:

Step-by-step explanation:

28% of an unknown number is (x)=56

28/100 of x=56

Answer:

1. x = 120°

2. x = 115°

Step-by-step explanation:

For the first question, you can see that the two lines are parallel. This means you can use any of the alternate interior angles, alternate exterior angles, corresponding angles, consecutive interior angles, and consecutive exterior angles.

You can see that the transversal cutting the two parallel lines make a 40° angle, and through alternate interior angles, the angle next to x is also 40°.

Because a straight line is 180°, the three angles that make up the straight line will add up to 180°. So:

x + 20° + 40° = 180°

x + 60° = 180°

x = 120°

For the second question, extend the line (the left one marked with 1 arrow) to make a smaller triangle attached to the parallelogram.

Because this is a parallelogram, opposite angles are congruent. So the opposite angle of x is also x.

Straight lines are 180°, so 180 - x will be what the angle measure is. If this is too confusing, refer to the image below.

Those two angles, 50° and (180 - x)°, will add up to be the exterior angle, which is also x.

So:

50 + 180 - x = x

230 = 2x

115 = x

x = 115

Answer:

-3.03

Step-by-step explanation:

divide -18.18 by 6

Answer:

t= -3.03

Step-by-step explanation:

In order to solve for t, we need to isolate it. We would do this by dividing both sides by 6:

[tex]t= -18.18/6[/tex]

Therefore t= -3.03

Given:

Consider the given equation is

[tex](4x)^{-2}(4x)^3(4x)^9=(4x)^?[/tex]

To find:

The missing value in the given equation and complete the equation.

Solution:

We have,

[tex](4x)^{-2}(4x)^3(4x)^9=(4x)^?[/tex]

Taking LHS, we get

[tex]LHS=(4x)^{-2}(4x)^3(4x)^9[/tex]

[tex]LHS=(4x)^{-2+3+9}[/tex]          [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]LHS=(4x)^{10}[/tex]

and,

[tex]RHS=(4x)^?[/tex]

Let the missing value be k.

For each equation LHS=RHS.

[tex](4x)^{10}=(4x)^{k}[/tex]

[tex]10=k[/tex]

Therefore, the missing value is 10 and the complete equation is [tex](4x)^{-2}(4x)^3(4x)^9=(4x)^{10}[/tex].

Answer:

m(RS) = 34

Step-by-step explanation:

Since, MK is the segment bisector of RS.

Therefore, segment MK will bisect RS in two equal segments RM and MS.

RM ≅ MS

m(RM) = m(SM) = 17

m(RM) + m(SM) = m(RS)

m(RS) = 17 + 17

m(RS) = 34

Answer:

The hat originally without the discount would be 19 or 20 dollars 20.00

Step-by-step explanation:

The tank will be empty in 32 minutes.

If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).

(a)

The table of values is given.

Rewrite the table of values as ordered pairs:

(5,108), (10,88), (15,68)

Since the difference between any two consecutive y values and the difference between any two consecutive x values is constant, the data shows a linear relation.

The slope of the line that passes through (5,108) and (10,88) is:

m = (88-108)/(10-5)

m = -4

The equation of the line with slope m = -4 and passes through (5,108) is:

y - 108 = -4(x - 5)

y = -4x + 20 + 108

y = -4x + 128        (1)

(b)

Substitute x = 0into equation (1):

y = - 4(0) + 128

y = 128

The tank is 128 ounces cleaner at the beginning.

(c)

Substitute y = 0 into equation (1):

0 = -4x + 128

4x  = 128

x = 32

Therefore, the tank will be empty in 32 minutes.

12x I think

Step-by-step explanation:

this is very confusing.

2x² + 2x - 4 = 2x ( x + 1 - 2 )

4x + 2x - 4

8x-4

4x = 2x ( x + 1 - 2)

8x + 2 - 2

8x + 4x
