QUICK!Lucy is trying to find a rational number between 3 \8
and 6 \7
. What would help her to find this number?

A)Divide 3\ 8 by 6\ 7
.
B)
Convert 3 \8 and 6\ 7 to fractions with a common denominator.

C)
Find a common numerator and multiply the denominators by this number.
Eliminate

D)
Find a number between 3 and 6 to get the numerator and add 8 and 7 for the denominator.

Answers

Answer 1

Answer: So,

In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.

LCM of 8 and 7: 56

Multiply each fraction by the appropriate form of 1:
$(3)/(8) * (7)/(7)\ AND \ (6)/(7) * (8)/(8)$

$(21)/(56)\ AND\ (48)/(56)$

We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.

The correct option is B.

What is the answer to 7/10 of 2.5 m equals how many centimetres

Answers

think of it this way
7/10= ?/2.5
the easiest way to do this is to cross multiply and divide
2.5*7/10
=17.5/10
=1.75 m

But we are looking for cm and 1 m is the same as 100 cm do we just multiply
1.75 x 100
=175 cm

Rewrite equation in vertex form y=x^2+4x+2

Answers

Answer: $y =(x+2)^2-2$

Steps:

The general vertex form of a parabola is as follows:

$y = a(x-x_v)^2+b$

where xv is the x coordinate of the vertex, a is the coefficient determining how wide/narrow the parabola is and whether it is open-up (+) or open-down (-), and b is the bias (vertical shift.

Transforming an expression into the vertex form involves completing the square step:

$y=x^2+4x+2\ny = x^2 + 2\cdot2 x+ 2 + 4 - 4= (x+2)^2-2\ny =(x+2)^2-2\n\implies x_v = -2,a=1, b=-2$

Your answer should be 16/9

$\bf \left( \cfrac{64}{27} \right)^{(2)/(3)}\implies \left( \cfrac{4^3}{3^3} \right)^{(2)/(3)}\implies \left( \cfrac{4^{3\cdot (2)/(3)}}{3^{3\cdot (2)/(3)}} \right)\implies \cfrac{4^2}{3^2}\implies \cfrac{16}{9}$

Drag the orange point on the cube to change its side length. Then set the base of the pyramid to the same dimensions as a face on the cube. Also set the height of the pyramid to the same side length as the cube. Note the volumes of the cube and the pyramid. Record the volumes for a few sets of heights and bases, and then calculate the ratio of the volumes. Be sure the dimensions for the cube and the pyramid are the same in each set. (You might see some discrepancies in the tool due to rounding of decimals.) Round your calculations for the ratio to the hundredths place. The first one has been done for you.
