Help!!!! I have rsm tomowrrow. can u also show me how to do it? thanks!

Answer:

x = 2.0172

Step-by-step explanation:

2.2^x+2.2^-3=5

-> 2.2^x+0.093914 = 5

-> + -0.93914    + -0.93914

-> 2.2^x = 4.906086

-> x = log(4.906086/log(2.2)

-> x = 2.0172

Answer:

9/9/108/126

Step-by-step explanation:

1/2bh is how you find the area of a triangle ! :)
This means that for both triangles, the area is 2 times the height, 9, then multiplied by one half. The area is 9 for both the left and right triangle.

The area of the rectangle is the product of the two lengths: 9 and 12, which is 108.

This means that the area of the entire trapezoid is 126.   :D

Answer:

y=1/2x+2

Step-by-step explanation:

The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.

To find the gradient is a little more tricky, but we can follow the formula:

[tex]\frac{rise}{run}[/tex], where rise is the vertical value and run is the horizontal value

So we sub in our values:

[tex]\frac{2}{4}[/tex]

And simplify:

[tex]\frac{1}{2}[/tex]

So now we sub in our new found values into y=mx+c:

y=1/2x+2

Answer: y = x/2 + 2 which is the 4th option from the top

Step-by-step explanation:

First find the slope which is (0-2)/(-4-0) = 2/4 = 1/2

So it's y = x/2 + c

Substituing (-4,0) into the equation we get

0 = -4/2 + c

0 = c-2

c = 2

So the equation is y = x/2 + 2 which is the 4th option from the top

Answer:

B. [tex](4}, {\frac{13}{4})[/tex]

Step-by-step explanation:

[] Let's draw a picture

-> See attached

[] Looking at the picture and seeing the words halfway being used, we can tell we will need to use the midpoint formula.

-> See attached

[] We will use the midpoint formula between Sarah's house (7, -2) and Mandy's house (3, 5) to find Cameron's house.

[tex](\frac{7+3}{2}, \frac{-2+5}{2} )[/tex]

[tex](\frac{10}{2}, \frac{3}{2} )[/tex]

[tex](5, \frac{3}{2} )[/tex]

[] Now we will use the midpoint formula between Cameron's house ([tex](5, \frac{3}{2} )[/tex]) and Mary's house (3, 5) to find Kayla's house.

[tex](\frac{5+3}{2}, \frac{\frac{3}{2} +5}{2} )[/tex]

[tex](\frac{8}{2}, \frac{\frac{13}{2}}{2} )[/tex]

[tex](4}, {\frac{13}{2}*\frac{1}{2} )[/tex]

[tex](4}, {\frac{13}{4})[/tex]

-> This leaves us with option B. [tex](4}, {\frac{13}{4})[/tex]

Have a nice day!

Answer: -1,-1 + -2,-1

Step-by-step explanation:

You first take the verticle line and then the horizontal line and then you add point be by point A so basically its supposed to be -1+(-1)+(-1)+(-2) if I'm right.

Answer:

A = 78 sq in

Step-by-step explanation:

Area of a triangle:

A = 1/2•b•h

= 1/2•26•6

= 78 sq in

Answer:$232

Step-by-step explanation:14.5x16=232

Answer:

$232

(If you want to round, the answer would be $200)

Step-by-step explanation:

This is just a one-step equation:

16 x 14.5 = $232

Answer:

Selling Price 250

Profit =5%

We are given to find the cost price of articles .

First we find the profit

► Profit = 250/100 × 5

► Profit = 2.5×5

► Profit = 12.5

► Cost Price = 250-12.5

► Cost Price = 237.5

So, the cost price of the article is 237.5

Selling price of the article.

Profit percentage %.

To do:

We have to find the cost price.

Solution:

Let the cost price of the article be .

Profitpercent = SP-CP/CP × 100

5 = 250-x/x x 100

5x = (250-x) 100

x = (250-20) 20

x = 250 (20) - 20x

x + 20x = 5000

21x = 5000

x = 5000/21

x = 238

Therefore; cost price of the article is Rs 238

Answer:

Decide if the evidence supports the claim well enough to convince most reader that its true.

Step-by-step explanation:

Answer:Decide if the evidence supports the claim well enough to convince most readers that it’s true.

Step-by-step explanation:

Answer:

8)  14

10) 1

12) 81

Step-by-step explanation:

For number eight, you have to multiply out by 2. For example,

9 x 2= 18

2 x 2= 4

7 x 2= 14

For number ten, you have to subtract by 9. For example,

51 - 42= 9

10 - ___= 9

the space would be 1 because 10-1 equals 9

For number 12, you have to multiply out by 9

5 x 9=45

10 x 9= 90

9 x9= 81

Answer: A=hbb2

Step-by-step explanation: For a triangle, we can find it by adding the lengths of its three sides. We can find the length of the fencing required for a triangular park by finding the perimeter of the triangle.

Answer:

$4

Step-by-step explanation:

Let x be the cost of a game of bowling and y be the cost to rent the shoes before the game then...

4x+y=28

6x+y=40

We can solve this system using elimination. In this scenario, we can eliminate y by subtracting the two equations...

-2x=-12

Divide both sides by -2

x=6

Plug 6 back in for x to solve for y

4(6)+y=28

24+y=28

Subtract 24 from both sides

y=4

It costs $4 to rent the shoes before bowling
