A.4000

B.360

C.36

D.3

Answers

Answer 1

Answer: B is the answer because you cross multiple the two fractions.
$(3)/(100) (x)/(12000)$
3 *12,000=36,000
36,000/100=360

Answer 2

Answer:

Answer:

THE ANSWER IS 360

please deal with it lol :)

good luck on the test

Ari thinks the perfect milkshake has 33 ounces of caramel for every 55 scoops of ice cream. Freeze Zone makes batches of milkshakes with 66 ounces of caramel and 88 scoops of ice cream. What will Ari think about Freeze Zone's milkshakes?

Answers

Answer:

Too much caramel.

Step-by-step explanation:

$(33)/(55) \: = \: (66)/(88) k$
$(3)/(5) \: = \: (6)/(8) k$
$(3)/(5) \: = \: (3)/(4) k$
$k \: = \: (4)/(5)$
Since, k ≠ 1,
Ari will think Freeze Zone's Milkshakes don't have the required quality.

Answers

Answer:

Yes

Step-by-step explanation:

10:12 and 30:36

you can simplify them first so

10:12=5:6

and

30:36=5:6 which is equivalent to the other ratio

or you can do

10:12

10 times 3 is 30 30:36 12 times 3 is 36

The area of a square is found by squaring one of its sides, (A = s2). A certain square has an area of z2 + 18z + 81. Factor the trinomial to find a side of the square.a. side = z + 27
b. side = z + 18
c. side = z + 9

Answers

A = s²
A = z² + 18 z + 81
z² + 18 z + 81 = z² + 9 z + 9 z + 81 = z ( z + 9 ) + 9 ( z + 9 ) =
= ( z + 9 ) ( z + 9 ) = ( z + 9 )²
Answer:
C ) side = z + 9

Answer:

option c is correct.

side = z+9

Step-by-step explanation:

Area of a square(A) is given by:

$A = s^2$

where,

s is the side of the square.

As per the statement:

A certain square has an area of $z^2 + 18z + 81.$

⇒ $A = z^2 + 18z + 81$

Substitute in [1] we have;

$z^2 + 18z + 81 = s^2$

Taking square root both sides we have;

$√(z^2 + 18z + 81) =s$

Using identity rule:

$(a+b)^2 =a^2+2ab+b^2$

then;

$√(z^2 + 2(1)(9)z + 9^2) =s$

⇒ $√((z+9)^2) =s$

Simplify:

$z+9 = s$

s = z+9

Therefore, a side of the square. is, z+9

Bc reflects about a line such that N is the reflection of B and O is the reflection of C. Point N is shown on the coordinate plane, but point O is not. What will the coordinates of point O be?

Answers

From my research, the coordinate points can be found on image below. Since N is the reflection of B and O is the reflection of C, if we were to draw a line to the right of N and a vertical line below C, the point of intersection of these two lines should give us the location of point O. Doing just that, point O is found at (5,5).

The coordinates of point O of the given Reflection is; 5, 5

How to find the point coordinates?

The coordinates point is missing and so I have attached it.

Now, from the question, we are told that N is the reflection of B and O is the reflection of C. Thus, from the attached image, drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines would give us the location of point O.

Drawing a line to the right of N and a vertical line below C, the point of intersection of these two lines which is point O has coordinates at (5,5).
