Answer:

58.29 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b) , substitute given values into formula

A = [tex]\frac{1}{2}[/tex] × 6.7 × (7 + 10.4)

   = 3.35 × 17.4

   = 58.29 cm²

Answer:

-x+y= -14 (get this equation to where you can easily plug it in for a variable)

y= x -14

5x +6y =26 (plug the value above in for y and then solve)

5x + 6 (x-14) = 26 (use the distributive property)

5x +6x - 84 = 26 (combine like terms on the left side)

11x - 84 =26 (add 84 to both sides)

11x = 110 (divide both sides by 11 to isolate the x-variable)

x= 10 (this is the value for x. plug it into the easier equation and solve)

-(10) +y = -14

y= -4

(10, -4) (this is the solution for the system of equations)

Answer:

•3/2 cm/s

Step-by-step explanation:

from (0, 0) to (6, 9). The graphed function rose 9 units (went up) and ran 6 units (shifted right). In slopes, we use this equation:

[tex] \frac{rise}{run} [/tex]

to find slopes. So ⁹⁄₆ is what we get. But ⁹⁄₆ simplified is ³⁄₂, so that's the answer.

Answer:

92

Step-by-step explanation:

161 divided by 7 is 23. so you just multiply 4 by 23. And that gets you the answer. Hope this helps:)

Answer:

x=92

Answer:

1) The equation to determine the the number of people who can go to the amusement park is 14.75 + 13.25·p = 94.25

2) The number of people who can go to the amusement park is people

Step-by-step explanation:

The given parameters are;

The amount the group of friends have to spend on parking and admission = $94.25

The cost parking = $14.75

The cost of tickets per person = $13.25

The variable we let to represent the number of people who can go to the amusement park be "p"

1) The equation that can be used to determine "p" is therefore, given as follows;

14.75 + 13.25·p = 94.25

2) Therefore, we have, by making "p" the subject of the above equation;

p = (94.25 - 14.75)/13.25 = 6

Therefore, the number of people who can go to the amusement park, p = 6 people.

Answer:

Answer: 6

Step-by-step explanation:

Equation: 13.25p+14.75=94.25

Step-by-step explanation:

Pi is a bit bigger than three(3.141592...) 3x3 = 9, but 3 times anything bigger than it, is more than 9.

eventually all of the offspring will have the genetic variation

Step-by-step explanation:

the variation was passed down to its offspring, and was favored, so it is now just part of its genetics, meaning all of the offspring from the original spiders offspring, will also have the genetic variation. hope this helps :)

Step-by-step explanation:

(x - 3 ) (2x + 4) = 0

Either

x - 3 = 0

Therefore x = 3

Or.,

2x + 4 = 0

2x = - 4

x = - 4 /2

Therefore x = -2

Now the value of x is 3 or - 2.

Hope it will help :)♥

Answer:

x = 3   &  x = -2

Step-by-step explanation:

(x-3) = 0    so x = 3    

(2x+4) = 0          so 2x = -4     x = -2

Answer:

12

Step-by-step explanation:

Key word: Most likely

First try to find the constant of proportionality

8/2= 4

4/4= 1

20/5=4

24/6=4

Since it says most likely we would say the constant of proportionality is 4.

Since they are asking for 3 homes runs we will do 3 times 4

[tex]3[/tex]×[tex]4=12[/tex]

The player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.

The constant of proportionality is the ratio between two directly proportional quantities.

Two quantities are directly proportional when they increase and decrease at the same rate.

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Finding the constant of proportionality :-

8/2= 4

4/16= 4

20/5=4

24/6=4

Since, the constant of proportionality is 4.

And, they are asking for 3 homes runs we will do 3 times 4

Therefore, 3 x 4 = 12

Hence, the player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.

Answer:

3

Step-by-step explanation:

To find the slope of the line, you can use the formula rise/run.

Every time the graph moves one unit across the x-axis, it moves three spaces up. Therefore,

Rise = 3

Run = 1

Now to plug this into our formula:

3/1 = 3

The slope of the line is 3.

Answer:

The amount Raphael spend on DVD including tax is $16.2

Step-by-step explanation:

Tax on DVD = 8%

Amount of tax = $1.20

We need to find the amount Raphael spend on DVD including tax.

Let the cost of DVD = x

We can write the equation: [tex]8\%\:of\:x=1.20[/tex]

Because the tax amount is 8% of actual cost and is equal to 1.20

Now solving to find x:

[tex]8\%\:of\:x=1.20\\8\%\times\:x=1.20\\\frac{8}{100}\times x=1.20 \\x=1.20 \times \frac{100}{8}\\x= 15[/tex]

So, the cost of DVD = $15

Now, The amount Raphael spend on DVD including tax = Cost of DVD + Tax

The amount Raphael spend on DVD including tax = 15 + 1.2

                                                                                    = 16.2

So, The amount Raphael spend on DVD including tax is $16.2
