HI!

So the square root of 128 is 11.31.

You would know that it is more than 11 since 11^2 is 121 which is 7 less than 128.

So the answer would be between 11.3 and 11.4

also 12^2 is 144

121 and 144 are 23 points away and that divided by 10 is 23/10. 23/10 is a little more than 2. so everytime 121 is added by 2, go up by .1

so....

121+2 = 123

11 + .1 = 11.1

123+ 2 = 125

11.1 + .1 = 11.2

125+2=127

11.2+.1=11.3

127+2=129

11.3+.1=11.4

and you would know that square root of 128 is between 11.3 and 11.4

Hope this helps!

gavmur [86]

3 $\frac{3}{35}$ pound of strawberry

Step-by-step explanation:

Given parameters:

Pounds of strawberry picked by Lexi =2 $\frac{7}{10}$

Pounds of strawberry eaten by Lexi sister = $\frac{7}{8}$

Unknown:

Pound of strawberry Lexi's sister ate = ?

Solution:

This is a fraction word problem.

Let pound of strawberry eaten by Lexi's sister = K

We can establish that:

Pound of strawberry eaten by Lexi sister x K = Pound of strawberry picked by Lexi

Mathematically we have:

$\frac{7}{8}$ x K = 2 $\frac{7}{10}$

The slope of a line is –2 and its y-intercept is (0, 3). What is the equation of the line that is parallel to the first line and

notsponge [240]

Answer:

D. y=-2x-6

Step-by-step explanation:

First start with what we know....

y = -2x + 3 (Slope Intercept Form)

Because of this we can eliminate B.

Parallel means that the lines wouldn't be touching which means they should have the same slope and the only one with the same slope is D.

Find the absolute value of the complex number 5 - 4i.

Damm [24]

I answered a similar question for someone else. The absolute value of a complex number is called the modulus. This represents the DISTANCE to the origin from the point on the imaginary + real plane.
the real horizontal distance is 5 and the imaginary vertical distance is in this case 4 (from -4i) the distance is 4. So to figure out this just use the Pythagorean theorem.
5^2 + (4)^2 = c^2
25 +16 = c^2
c^2 = 41c = 6.4 So option D.
