Evaluate 3.6x +4.5y when x=3 and y=7. 3.6+4)*45.999 3.6•(3) +4.5. (C) = (10.8) + ( ) L​

We're assuming the TV is a rectangle, meaning all corners have right angles.

From the given information, we have a right triangle with a height of 39 inches, hypotenuse, of 80 inches, and an unknown base width.

Using Pythagorean's theorem:

[tex]a^2+b^2=c^2[/tex]

[tex]b=\sqrt{c^2-a^2}[/tex]

c = 80 and a = 39

[tex]b=\sqrt{80^2-39^2}[/tex]

[tex]=\sqrt{4879}[/tex]

Using a calculator and rounding to the nearest tenth gives

[tex]\approx 69.8 \text{ inches}[/tex]

Answer:

22.62 cm exactly or limited to de precision of this calculator (13 decimal places). Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Answer:

22.6

Step-by-step explanation:

circumference is pi x diamter so:

7.2 x pi (3.142)

=22.61

round it so 22.6

The red graph intersects the y-axis at (0, 1).  This is the "y-intercept."

Answer:

When 2 angles are put together, they must have a total of 180 degrees.

Step-by-step explanation:

The measure of the missing angle is 141 degrees.

Answer:

45 units

Step-by-step explanation:

combine like terms

w+2w+w-1+21-8+2w+6 = 8w-3

replace w with 3

8(6)-3 = 48 - 3 = 45

Answer:

A

Step-by-step explanation:

It's one or the other, so the two on the graph won't connect, and each of them are greater/less than, NOT "or equal to" so both the circles would be closed. When thinking of these, forget about the x and just read greater than 5. On a graph the greater numbers are to the right, so the arrow would be pointing that way

Answer:

y=4/9

Step-by-step explanation:

Substitute 2y into the x

2(2y)+5y=4

4y+5y=4

9y=4

y=4/9

Answer:

5:3

Step-by-step explanation:

Answer:

x must be 3

Step-by-step explanation:

First, combine like terms.  (-5/3)x - (1/3)x = - 3 - 3 = -6

Then (-6/3)x = -6, or 2x = 14.  Then x must be 3.

Check:  is (-6/3)(x) = -6 true for x = 3?  Is 2x = 6 true for x = 3?  YES

Answer:

Answer: 10.3 years

Step-by-step explanation:

To solve this you can use the Rule of 72.

This rule enables us to find out the amount of time it would take for a quantity to double if it is growing at a certain rate.

Formula is:

= 72 / Interest rate as whole number

= 72 / 7

= 10.3 years

Answer:

-4 + 10 and 8 - 2

Step-by-step explanation:

They both equal to 6

Answer:

x =2, y =0

Step-by-step explanation:

First we can add the equations to get rid of the y terms in each.

Adding them results in 16x = 32

Dividing by 16 gives us x=2

Substituting this back into equation 1 gives us 8(2) -4y =16

Simplifying,

16 - 4y =16

-4y = 0

y = 0

Answer:

I think D.

Since it is mystery it would be a surprise, which could be any mix of something.

Step-by-step explanation:

You did not provide a list of equations for us to select from.

Let me see if I can put together.

Distance = rate times time (in hours).

Let x = time of the trip in hours.

D = rx

Let D = 295 miles.

Let r = 65 mph.

Here is your equation: 295 = 65x

Answer:

your answer should be C.

The transformation of the parent function f ( x ) = | x | by a compression of 5 units is given by g ( x ) = ( 1/5 ) | x |

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = | x |   be equation (1)

On simplifying , we get

when the function is stretched vertically by a factor , we get

Vertical stretch by a factor k: y = k × f(x)

And , when it is compressed by a factor of k = 5 units

The transformed function is g ( x ) = ( 1/5 ) | x |

Hence , the transformed function is g ( x ) = ( 1/5 ) | x |

Answer:

3 2/3

Step-by-step explanation:

If the mean is 11 and there are 5 numbers then their sum is 5 × 11 = 55 We have the ratio of parts being a : b : c : d : e → 1 : 2 : 3 : 4 : 5 so the total count of parts is 1 + 2 + 3 + 4 + 5 = 15. a-1/15x55=55 divided by 5/ 15 divided by 5=11/3=3 2/3
