How many times does 3 go into 28? let's see 28÷3 is 9.333 so...9 whole times, thus 9 * 3 is 27 so

$\bf \cfrac{28}{3}\implies \cfrac{27+1}{3}\implies \cfrac{27}{3}+\cfrac{1}{3}\implies 9+\cfrac{1}{3}\implies 9\frac{1}{3}$

1A) For the right triangle from the middle of one edge to the center of the base, the side "adjacent" to the angle is (82 m)/2 = 41 m. The height is the side of that triangle that is "opposite" to the angle. You know from your trig definitions that
.. tan(52°) = "opposite"/"adjacent"
.. tan(52°) = height/(41 m)
.. height = (41 m)*tan(52°) ≈ 52 m . . . . . . . 3rd selection

1B) Same deal.
.. tan(52°) = height/(side/2) = 2*height/side
.. side = 2*147 m/tan(52°) ≈ 230 m . . . . . . 4th selection

2) The sine is the ratio of opposite to hypotenuse. Side BC is opposite angle A, and side AB is the hypotenuse
.. sin(A) = (8√3)/16 = (√3)/2

An office manager budgeted $400 for

Stels [109]

Answer:

B. 7

Step-by-step explanation:

To find this out, first, we multiply 89*2, which is 178, the amount already spent on toner.

Then, we add 27 to this to find the total amount spent so far. This comes out to $205 spent so far.

To find out how much we have left to spend, we subtract the amount spent from the original.

400-205 = $195, the amount of money left.

To find out how much paper we can buy, we divide the cost of one paper box, by the amount of money we have left.

195/27 = 7.222222222222222222222222222222

Since we cannot buy 7.222222222222222222222222 boxes, we can only buy 7. This is the answer.

If you reflect any shape across the x-axis and then rotate it 90° clockwise about the origin, do you get the same result as if y

Setler79 [48]

Answer:

Yes, reflecting a shape across the x-axis and then rotating it 90° clockwise about the origin gives the same results as reflecting it across the y-axis followed by rotating it 90° counterclockwise about the origin. This means these two sequences of transformations are equivalent.

!!HELP!! algebra two!! multiply and combine like terms to write as the sum of difference of monomials!! a-i !!!explanation, if p

vazorg [7]

Answer:

a. 10a + 8a²

c. 12z + 3z²

e. -20 + x + x²

g. -64 + 9z⁴

i. y¹⁰⁰¹ + 8y¹³²⁰⁰

Step-by-step explanation:

According to the Six Exponential Rules, whenever you divide terms, you subtract the exponents, and of course whenever you multiply terms, you add the exponents.

a. The variables have an invisible degree term of 1, so when multiplied, you get 8a².

c. ⅛ of 24 and 96 means dividing both numbers by its multiplicative inverse, which is 8: ⅛[24] → 24 ÷ 8; 3; ⅛[96] → 96 ÷ 8; 12. Then of course, you still have to follow the exponential procedure.

e. This is just like the Quadratic Equation, y = Ax² + Bx + C. All you have to do is do what I like to call FOIL:

F - Multiply the first terms in each set of parentheses FARTHEST TO THE LEFT

O [Outermost] - Multiply the first term in the first set of parentheses FARTHEST TO THE LEFT by the last term in the second set of parentheses FARTHEST TO THE RIGHT

I [Innermost] - Multiply the last term in the first set of parentheses FARTHEST TO THE RIGHT by the first term in the second set of parentheses FARTHEST TO THE LEFT

L - Multiply the last terms in each set of parentheses FARTHEST TO THE RIGHT

Doing this will give you the above answer.

g. See explanation letter e.

i. Now, as I mentioned before, when you multiply terms, you add the exponents. In addition, that decimal in the far right corner, is equivalent to ⅛, and ⅛ of 8 is 1, so we know that 1 is our INVISIBLE coefficient next to the y, then you just add 1 to 1000 in the exponents because of the invisible degree of 1.
