hope it helped have a good day mate

Answer:

3.5 hours

Step-by-step explanation:

227.5÷65=3.5

Answer:

No

Step-by-step explanation:

So if the director paid $90 for 12 visors, we need to find how much one cost so 90/12 = 7.5

Then to find the cost of 15 visors, multiply 7.5 by 15 to get 112.5

now add 112.5 to 90 to see if it stays within the budget of $200, 112.5 + 90 = 202.5, so NO there is not enough money in the budget to buy 15 more sun visors.

Answer:

(A) 490ft.

(B) 2.8 miles

Step-by-step explanation:

Important points to note:

- The limestone layer is thought or assumed to slope downward in a straight line.

- 2 miles west of Seiling, the limestone layer was found at a depth of 220ft.

- 3 miles west of Seiling, the limestone layer was found at a depth of 270ft.

(A) What would you expect to be the depth of the limestone layer, 5 miles west of Seiling?

The expected depth of the limestone layer is:

2 miles + 3 miles = 5 miles

220ft + 270ft = 490ft

(B) Your budget will allow you drill a well that is 275ft deep. How far west of Seiling (in miles) can you go, to drill the well?

If 490ft  ~  5 miles

then 275ft  ~  K miles

K = [275 x 5] / 490  = 2.80612245 miles

Rounding to 1 decimal place, the distance is 2.8 miles.

Answer:

The area of the photograph is:  [tex]A=x^2-4[/tex]      

Step-by-step explanation:

Given

The length of rectangular photograph = [tex]l[/tex] = (x + 2) inches

The width of rectangular photograph = [tex]w[/tex] = (x - 2) inches

To determine

The area of the photograph

Important Tip:

Given that the photograph is in the shape of a rectangle. Thus, we can use the formula involving the area of a rectangle to determine the area of a photograph.

The Area of the photograph can be determined using the formula

[tex]A = wl[/tex]

where

now substituting [tex]l = (x + 2)[/tex] and [tex]w = (x-2)[/tex] in the formula

[tex]A = wl[/tex]

[tex]A = (x-2) (x+2)[/tex]

Apply Difference of Two Squares Formula:  [tex]\left(a-b\right)\left(a+b\right)=a^2-b^2[/tex]

[tex]A=x^2-2^2[/tex]       ∵ [tex]a=x,\:b=2[/tex]

[tex]A=x^2-4[/tex]        ∵ [tex]2^2=4[/tex]

Therefore, the area of the photograph is:  [tex]A=x^2-4[/tex]      

Answer:

(-4,-5)

Step-by-step explanation:

1. Image is the points after the transformation

2. Pre-Image is the original points

3. our x value is left to right and our y value is up and down (x,y)

4. Our points are (-4,2)

5. They first want us to translate three units up, so we add to our y value (y is up and down)

6. 2+3 = 5

7. Our new points are (-4,5)

6. Now we are asked to reflect over the x axis. Remember their are a lot of rules concerning reflections. For a reflection across x-axis our equation is this : (x,y) → (x,-y)

7. (-4,5) → (-4,-5)

8. (-4,-5) is our answer

Step-by-step explanation:

H0 : µ ≤ 26.9

Ha : µ > 26.9

a. since the null hypothesis is rejected, we would accept the alternative hypothesis and come to the conclusion that there is enough evidence that beer and cider consumption are higher than 26.9 in the city.

b. type 1 error happens when we reject a true null hypothesis.

this error error in this question would be that our conclusion that beer and cider consumption is greater than 26.9 is not true. what is true is that it is equal to or less than 26.9.

the consequence is that is h0 is false it would be harder to reject it at a lower level of significance.

c. type ii error happens when the null hypothesis is accepted even though it is false. here, error would be that cider we accepted that cider and beer consumption is less than or equal to 26.9 when it is actually greater than 26.9

the consequence is that it would be harder to accept a true h0 at a high level of significance

Answer:

a. The initial amount of money that was left in this savings account was of 5000.

b. Decrease of 2% each year.

Step-by-step explanation:

Exponential function:

An exponential function, with an initial value of A(0), and a decay rate of r, as a decimal, is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In this question, we have:

[tex]y = 5000*(0.98)^x[/tex]

a. What was the initial amount of money that was left in this savings account?

This is y(0) = 5000

The initial amount of money that was left in this savings account was of 5000.

b. What is the percent of change each year in this savings account?

First as a decimal.

1 - r = 0.98

r = 1 - 0.98

r = 0.02

So a decrease of 2% each year.

Answer:

x^2+5x-9

Step-by-step explanation:

First multiply 6x2 because that's a number that isn't solved in the parenthesis.

(x^2+5x-4) - (12-7)

Then you subtract 12-7 which equals 5.

(x^2+5x-4)-(5)

You now take the parenthesis off

x^2+5x-4-5

-4-5 equals -9

Now you get the answer: x^2+5x-9

Step-by-step explanation:

Answer: kimi is 22

Step-by-step explanation:

Answer:

Kimi is 11 years old

Step-by-step explanation:

We can read 'twice Kimi's age' as Kimi's age times 2 and

'14 years younger' as  minus 14.

Our equation is

2(Kimi's age)-14= Marcus' age

Since Marcus is 8:

2(Kimi's age)-14= 8

Now we manipulate the equation so that it equals Kimi's age. Remember that whatever we do to the right side, we also do to the left.

First we add 14 to both sides

2(Kimi's age)-14(+14)= 8(+14)

2(Kimi's age)= 22

Then we divide by 2

2(Kimi's age)/2= 22/2

Kimi's age=11

Usually we would us X to represent our unknown, Kimi's age, but I left it as Kimi's age so that it is easier to follow.

Answer:

A is 13

B is 5

C is 0.25

And D is 4.58 or 4.6

Good Luck!

Answer:

A) 0.2 + 7.9 + 3.8 + 1.1 = 13

B) -5.6 + 5 + 4.6 + 1 = 5

C) 3 1/6 - 4 3/4 + 1 5/6 = 1/4

D) 2 1/12 + 3 1/6 - 1 1/12 = 4 1/6

Step-by-step explanation:

A) 0.2 + 3.8 = 4... 7.9 + 1.1 = 9... 4 + 9 = 13

B) 4.6 + 1 = 5.6... 5.6 - 5.6 = 0... 0 + 5 = 5

C) 3 1/6 + 1 5/6 = 5. 5 - 4 3/4 = 1/4

D) 2 1/12 - 1 1/12 = 1. 1 + 3 1/6 = 4 1/6

-8 divided 2 = -4

-14 divided 2 = -7
