We are asked in the problem to determine the value of x in the equation <span>4x² + 2x = 7 using completing the square method. in this case,

</span><span>4x² + 2x = 7 
x2 + 0.5 = 1.75
(x + 0.25)^2 - 0.0625 = 1.75
</span>(x + 0.25)^2 = 1.8125
<span>x+0.25=1.3462
</span>x1 =1.0963

Trevor Linden, a former player for the Vancouver Canucks, is 1.93 m tall. On a hockey card, he is 5.4 cm tall. What scale was us
Anastaziya [24]

Answer:

scale  used to print the hockey card is 27/965

scale  used to print the hockey card in decimal  is 1/35.74

Step-by-step explanation:

we know that in scale problems

scale is used in drawing to enlarge or reduce size of object by a certain amount

scale = size of object in drawing/ actual size of object

Height of trevor = 1.93 m

we know that  1 m = 100 cm

Height of trevor in cm = 1.93 m*100 = 193 cm (actual size)

(this is done so that unit of measurement is same for card and trevor's height i.e cm)

Trevor's card on hockey card = 5.4 cm(size in drawing)

scale used = Trevor's card on hockey card /Height of trevor in cm

                    = 5.4/193 = 54/ 1930 = 27/965

scale  used to print the hockey card is 27/965

scale  used to print the hockey card in decimal  is 1/35.74

Find the ratio of Rs.50 to 100 paise​
inna [77]

Answer:

50:1

Step-by-step explanation:

Rs50=Rs50

100 paise= Rs1

Ratio = 50:1          [ cant be simplified further]

I hope im right!!

Another way:

Rs50= 50 x 100 = 5000 paise

100 paise= 100 paise

Ratio = 5000: 100

\frac{5000}{100} ÷ \frac{100}{100} = \frac{50}{1}

Ratio = 50:1

The owner of a souvenir shop wants to order some custom printed mugs and t-shirts what is the price per t-shirt for 75 T-shirts
lara31 [8.8K]

Answer:

The price per t-shirts is $8.5.

Step-by-step explanation:

Let us assume the price per t- shirt = $m

The cost of 75 t-shirts  =   $637.50

Now, the total cost for 75 t-shirts = 75 x ( cost of 1 t-shirt)

⇒  $637.50 = 75 x ( m)

 ⇒ m =  $637.50 / 75

   or, m = 8.5

Hence, the price per t-shirts is $8.5.

Please I need help and it has two answers for each one
Lelechka [254]

Answer:

1st Q: 3rd option, 2nd Q: 2nd, 4th, and 5th options

Step-by-step explanation:

For the first one, since the coefficient of the 2nd degree term is negative, the graph of the parabola will look downward, f(x) getting closer to infinity as the absoloute value of x gets larger.

For the second one, let f(x)=0 and solve the quadratic function with factoring. The equation can be rewritten as (x-12)(x+6)=0, so the roots are 12 and -6, which are x-intercepts. The y-intercept is the constant term of quadratic functions, so -36 is the y-intercept.
