dont know the shape of the tank. we

dont know what formula to use. i just the

formula for a cyclinder which is pi (3.14) time the r^2 ( radius squared)

times the height (16) and the the answer is 39408.13825 rounded this is number D.

please note i could only solve the first problem. not the plastic cover

but i think it is A

Answer:

Its D

Step-by-step explanation:

If r is less than q, then it is on the left side because that is the lowest position avaliabe on the number line. If s is q+1, that means s is one more than q so s is bigger than q. If q is more than r and less than s, it is in the middle of those two. So, r is on the left most side, q is in the middle, and s is on the right side because it is the most.

Elsa’s friend borrows $400 with an interest rate of 1.5%. How much interest will she pay after 4 years?

Answers

Formula I = P x r x t

p is the principal amount, $400.00

r is the interest rate 1.5% a yea (0.015 in decimal)

t is time involved 4 years

so t is 4 year time periods

To find the simple interest we multiply 400 x 0.015 x 4 to get $24.00

so if you borrowed the $400 dollars you would now owe $424

Answer: so it's $24 interest or $424 since it's usually added to the principal

Please help me and pls answer all of them. I really need help... Plssssss

Answers

Answer:

Step-by-step explanation:

Ok, so if there is no number in front of a variable (the letters), there is always a one. So you multiply them like this:

7 x 1b x 4 x 1a x 2 = 56ba

1c x 5 x 1b x 4 x 1a = 20cba

Since there is only a 1 in front of the variables, you can basically just multiply the numbers without variables and then mutiply that times one. Don't forget to add the variables into the answer.

6 x 1p x 4 x 5 x 1w = 120pw

1t x 2 x 1t x 1s = [tex]2t^{2} s[/tex]

Y=2x+19

I could be wrong

y = 4(x) + 7 - since the multiples of x are increasing at a lesser rate than the ones of y, it shows that x needs to be multiplied by a higher value. you could find the value x by plugging in different values <13, then find a common number to add that will give you the y output.

The height of the building and the distance between the house and the ladder are the legs of the triangles. He set up the formula correctly but plugged in the values in the incorrect areas

Let’s use his formula

Leg A^2 + Leg B^2 = Hyp^2

The house is one of the legs and the ladder is the hypotenuse

(15)^2 + Leg B^2 = (17)^2

Let’s isolate Leg B because we hate it and need to find it’s value.

Leg B^2 = (17)^2 - (15)^2

Let’s get rid of these exponents

Leg B^2 = 289 - 225

Subtract

Leg B^2 = 64

Leg B = 8
