Answer:

1/16

Step-by-step explanation:

(1/4×1/4)-6÷1/3+2

(1/16) - 6 ÷ 1/3 + 2

1/16 - 2 + 2

1/16 - 32/16 + 2

-31/16 + 2

-31/16 + 32/16

= 1/16

Answer:

m^20n^4/p^4q^8

Step-by-step explanation:

Given the expression (m^5n/pq^2)4

This can be written as;

(m^5n/pq^2)4

= (m^5)^4n^4/p^4(q^2)^4

= m^20n^4/p^4q^8

Hence the equivalent expression is m^20n^4/p^4q^8

Answer:

Always sometimes

Step-by-step explanation:

A triangle has an interior angle total of 180 degrees, and if any of those three angles are obtuse, that forms an obtuse triangle.

Now suppose we had a triangle with two acute angles, but not having those two angles add up to more than 90 (consider 30 degrees and 20 degrees).

We can find the unknown angle through some quick subtraction (180 - 30 - 20 = 130).

Since one of the angles is an obtuse angle, this triangle is an obtuse triangle, even though this triangle possesses two acute angles (try drawing a picture, it'll help you visualize it), meaning that a triangle with two acute angles will only sometimes be an acute angle (when those two angles add up to an angle measure more than 90, meaning that the last angle will also be less than 90, making an acute triangle).

Hope this helps!

Charlie will receive the ring in 21 months.

It is a method of buying something in which a person can make a downpayment to buy something at a store and the store holds the item on their behalf until the last payment is done after which they gain possession of it.

Charlie has put in a ring on layaway. This means that he will only receive the ring in 21 months after he has finished paying all the installments. He will not gain possession of the ring right away after making the downpayment of $85.

Thus, we have found that Charlie will receive the ring in 21 months. The correct answer is option A.

Answer:

Y-intercept=5 Slope=-1/4

Step-by-step explanation:

Plot a point on (0,5)

From that point, you can either go down 1 point and right 4 points, or you can go up 1 point and go left 4 points.

Whichever one you choose, plot a point after each 2 movements

if this is too confusing, another point would be (4, 4) then make a line through both points.

Answer:

The company's overall profits were 450,000.

Step-by-step explanation:

We know that Jerome received 150,000. This 150,000 also counts as 1/3 of the profit, so if we put it as an equation, it gives us this:

1/3x = 150,000  We need to work out how much the overall profits are, which I've labelled as x.

x = 450,000  Here we multiply 150,000 by 3 to get x on its own, or you could also divide by 1/3.

I hope this makes sense to you. ^-^ If not, do let me know.

Answer:

  (5, 1) or maybe (h, k)

Step-by-step explanation:

The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).

In the generic vertex form ...

  f(x) = a(x -h)² +k

the letters (h, k) are used to represent the vertex.
