Answer:

24 hours

Step-by-step explanation:

First find Unit Rate which is, 6 ÷ 3 = 2 memos per hour.

2. We know she writes 2 memos in one hour so, \frac{hour}{memos} , \frac{1}{2} = \frac{?}{48} .

? is equal to 24 hours since 48 ÷ 2 = 24

Answer:

24 hours.

Step-by-step explanation:

We will solve this problem by unitary method.

∵ Time taken to type 6 memos = 3 hours

∴ Time taken to type 1 memos = $\frac{3}{6}$ hours

∴ Time take to type 48 memos = $\frac{3}{6}$ × 48

= $\frac{1}{2}$ × 48

= 24 hours

It will take 24 hours to type 48 memos.

Len [333]

We can use this equation to solve this problem:

t=p+(p⋅r)

Where:

t is the total price paid: 58.31 for this problem

p is the price before taxes: What we are solving for in this problem.

r is the tax or VAT rate: 19% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 19% can be written as 19100 or 0.19.

Substituting and solving for p gives:

58.31=p+(p⋅0.19)

58.31=1p+0.19p

58.31=(1+0.19)p

58.31=1.19p

58.311.19=1.19p1.19

49=1.19p1.19

49=p

p=49

Now, we can find how much the VAT was by taking 19% of 49:

19%×49=0.19×49=9.31

Another was to solve this is to subtract the price without the tax or VAT from the total price giving:

58.31−49=9.31

4vir4ik [10]

We have to choose the correct answer for the center of the circumscribed circle of a triangle. The center of the circumscribed circle of a triangle is where the perpendicular bisectors of a triangle intersects. In this case P1P2 and Q1Q2 are perpendicular bisectors of sides AB and BC, respectively and they intersect at point P. S is the point where the angle bisectors intersect ( it is the center of the inscribed circle ). Answer: P.

The equations 3 x minus 4 y = negative 2, 4 x minus y = 4, 3 x + 4 y = 2, and 4 x + y = negative 4 are shown on the graph below.

Answer:

(–1.4, 1.5)

Step-by-step explanation:

The blue line and the purple line are the lines corresponding to the equations of interest. Their point of intersection is in the 2nd quadrant, so is nearest to ...

(–1.4, 1.5)

It can be useful to understand that for equations in standard form:

ax +by = c

the x- and y-intercepts are ...

x-intercept: c/a . . . . value of x for y = 0
y-intercept: c/b . . . . value of y for x = 0

For the equations of interest, the first has intercepts of ...

x=2/3, y=1/2 . . . . graphed line makes a 1st-quadrant triangle with the axes (blue line)

And the second has intercepts of ...

x=-1, y=-4 . . . . graphed line makes a 3rd-quadrant triangle with the axes (purple line)

Since the purple line has a steeper slope, the point of intersection of the lines will be in the 2nd quadrant. There is only one 2nd-quadrant answer choice: (-1.4, 1.5).
