Answer 1

Answer:  x=7

Step-by-step explanation:  

plug y into equation...

x-(-4x+23)=12

solve...

x+-1(-4x+23)=12

x+-1(-4x)+-1(23)=12

x+4x-23=12

5x-23=12

5x=35

x=7

In order to paint the house, Wyatt multiplies the area of the base times the height then adds half the area of the base times the height.

Explain whether or not Wyatt correctly calculated the surface area of the house.

Answers

9514 1404 393

Answer:

  Wyatt is incorrect in his calculations

Step-by-step explanation:

The units of base area are square inches. When Wyatt multiplies that by height, he gets a number with units of cubic inches. This is a volume, not an area. If Wyatt is trying to compute an area, he is doing it incorrectly.

_____

Additional comment

I find units analysis to be very helpful in keeping calculations of speed, distance, area, volume, acceleration, velocity, and other physical phenomena straight. If the units come out right, chances are much better that the numbers are being combined appropriately.

Wyatt may need to be using the perimeter of the base, rather than the area of the base. Without the diagram it is tough to tell what the calculation should be.

Find the following
(u•w)(2)=
(w•u)(2)=

Answers

Answer:

[tex](u \circ w)(2) = -34[/tex]

[tex](w \circ u) = -49[/tex]

Step-by-step explanation:

We are given these following functions:

[tex]u(x) = 4x + 2[/tex]

[tex]w(x) = -5x + 1[/tex]

The first step to solve this question is finding the composite functions. So

[tex](u \circ w)(x) = u(w(x)) = u(-5x+1) = 4(-5x + 1) + 2 = -20x + 6[/tex]

[tex](w \circ u)(x) = w(u(x)) = w(4x + 2) = -5(4x+2) + 1 = -20x - 9[/tex]

At x = 2

Now we replace x by 2 in each of the functions. So

[tex](u \circ w)(2) = -20(2) + 6 = -40 + 6 = -34[/tex]

[tex](w \circ u)(2) = -20(2) - 9 = -40 - 9 = -49[/tex]

what is the scale factor of the small triangle to the large triangle?

Answers

Answer:

I'm pretty sure it's 4.3?

Step-by-step explanation:

Because you divide the larger triangles side first because you are figuring out the scale factor of the small triangle to the larger triangle, not the other way around.

Sorry if i'm wrong

Answer:

first, find the area of the small triangle: 3 times 3 equals 9 divided by 2 equals 4.5.

second, find the area of the big triangle: 13 times 13 equals 169 divided by 2 equals 84.5.

Find difference: 84.5 minus 4.5 equals 80

Let F be the set of fractions in simplest form between 0 and 1 that can be written with a single-digit denominator. Find F and |F|​

Answers

Answer:

|F| is 27, the whole F is "listed" below.

Step-by-step explanation:

The set of possible denominators is the numbers from 2 to 9. Each of them produces a single fraction for each numerator that's coprime to it.

Let's list those for each:

2: 1

3: 1 2

4: 1 3 (2 is not coprime)

5: 1 2 3 4

6: 1 5 (2 3 and 4 are not coprime)

7: 1 2 3 4 5 6

8: 1 3 5 7

9: 1 2 4 5 7 8 (3 and 6 are not coprime)

To make any number from F, just take the denominator from the rows and the numerator from the list. The size of F is 1 + 2 + 2 + 4 + 2 + 6 + 4 + 6 = 27

The set/number of fractions F for each denominator are ; ( 1, 2, 2, 4, 2, 6, 4, 6 ) .while the value | F | = 27

Given that the set of fractions are between 0 and 10. the possible single digit denominators will be ( 2 through 9 ). also the single digit denominators will have to produce a single fraction where its numerator is coprime to the denominator.

note : coprime numbers are a set of numbers whose HCF (highest common factor ) equals 1

denominators                co-prime numerators

    2                                             1

     3                                           1,  2

     4                                           1,  3  

     5                                           1, 2, 3, 4

     6                                           1, 5  

     7                                           1, 2, 3, 4, 5, 6

     8                                           1, 3, 5, 7

     9                                           1, 2, 4, 5, 7, 8

next : Determine the size of F i.e. | F |

The size of F = ∑ number of coprime numerators for each denominator

                     =  1 + 2 + 2 + 4 + 2 + 6 + 4 + 6 = 27

set of fractions F for each single digit denominator  = ( 1, 2, 2, 4, 2, 6, 4, 6 )

Answers

Answer:

156.6 meters squared

Step-by-step explanation:

There are 3 triangles for the sides. The area for a triangle is one half base times height. So we are doing one half of 9 times 9. This is 40.5. Since there are 3 of them we can just multiply 40.5 times 3 to get 121.5. And now to solve for the base triangle, it is one half of 9 times 7.8. We get 35.1. Now add together 121.5 and 35.1. We get 156.6. Now since this is surface area it is meters squared.
