The best way to find it is to reduce each ratio you work with to its
lowest terms,and see which ones are equal. To reduce a ratio to its
lowest terms, divide each number by their greatest common factor.

First, the one that you're trying to match: 49:35 .
The greatest common factor of 49 and 35 is 7 .
Divide each number by 7 . . . 7:5 . . . that's what you have to match.

7:4
Their greatest common factor is ' 1 '.
No help at all, and this one is not it.

14:25
Again, their greatest common factor is '1 '.
No help at all, and this one is not it.

21:15
Their greatest common factor is ' 3 '.
Divide both numbers by 3 . . . 7:5 .
That's it !

49=7*7
35=7*5
so 49:35=7*7:7*5=7:5
7:4 is not 7:5
14:25 also isn't 7:5
21:15=3*7:3*5=7:5
the answer is 21:15

Your computer-supply store sells two types of inkjet printers. The first, type A, costs $237 and you make a $22 profit on each o

Vera_Pavlovna [14]

The minimum cost option can be obtained simply by multiplying the number of ordered printers by the cost of one printer and adding the costs of both types of printers. Considering the options:
69 x 237 + 51 x 122 = 22,575
40 x 237 + 80 x 122 = 19,240
51 x 237 + 69 x 122 = 20,505
80 x 237 + 40 x 122 = 23,840
Therefore, the lowest cost option is to buy 40 of printer A and 80 of printer B

The equation, x + 2y ≤ 1600 is satisfied only by options:
x = 400; y = 600
x = 1600
Substituting these into the profit equation:
14(400) + 22(600) - 900 = 17,900
14(1600) + 22(0) - 900 = 21,500
Therefore, the option (1,600 , 0) will produce greatest profit.

Suppose that your test statistic is t(99 ) = -2.8888. Round the test statistic to two places after the decimal point.

Scrat [10]

Answer:

t(99)= -2.89

Step-by-step explanation:

-To places after the decimal point is equivalent to rounding off to the nearest hundredth.

-To round off to the nearest hundredth, we check the thousandths digit:

If the thousandths digit is less than5, we round down to the previous hundredth.
If the thousandths digit is greater than 4, we round up to the next hundredth:

Hence, $-2.8888\approx-2.89$

Graph the equation.

omeli [17]

9514 1404 393

Answer:

see attached

Step-by-step explanation:

Sometimes the quadratic is easier to graph if written in vertex form.

y = -x^2 -6x -3

= -(x^2 +6x) -3

= -(x^2 +6x +9) -3 +9

= -(x +3)^2 +6

This is a parabola that opens downward, with its vertex at (-3, 6). Unlike the one shown in the graph already, its scale factor is 1, so it will appear narrower than the one given with the problem statement.
