What is 33 %of what number is 1.45
Anna007 [38]
To find 33% of 1.45 we have to tranform 33% into decimal of traction
33% is 0.33 or \frac{33}{100} and multiply if by 1.45
so
0.33*1.45=0.4785
or
1.45*\frac{33}{100}= \frac{957}{2000}

Joey wants to build a rectangular garden. He plans to use a side of a river for one side of the garden, he will not place fencin
NikAS [45]

We let x and y be the measures of the sides of the rectangular garden. The perimeter subtracted with the other side should be equal to 

                                                   2x + y = 92

The value of y in terms of x is equal to,

                                            y = 92 – 2x

The area is the product of the two sides,

                                                                        A = xy

Substituting,

                                                            A = x (92 – 2x) = 92x – 2x2

Solving for the derivative and equating to zero,

                                                            0 = 92 – 4x  ; x = 23

Therefore, the area of the garden is,

<span>                                                            A = 23(92 – 2(23)) = 1058 yard<span>2</span></span>

I will give brainlyist to the first right answer

To find equivalent expressions, distribute the 7 into (-3/4x - 3)

7(-3/4x) = -21/4x, which simplified is -5 1/4x
7(-3) = -21

Put together, this is -5 1/4x - 21 (answer 1)

Another way to write an equivalent expression would be to not simplify 7 times the distributed term. You could write 7(-3/4) + 7(-3) which makes #5 correct as well. #5 is 7(-3/4x) - 7(3). If this was simplified, it would equal answer choice 1.

#2 is not correct because 7 times -3/4x does not equal -7 3/4x

#3 is not correct because -21/4 simplifies to -5 1/4, not -6 1/4

#4 is not correct because 7(-3) does not equal -4
