You can Solve the -3/4 + 1 1/4 by...
-3/4 + 1/4 = -2/4 = -1/2

1 + -1/2 = 1 - 1/2 = -0.5

Then you go in the number line and go two back from the zero mark.

Hope this helps! :)

Brilliant_brown [7]

You are correct, it would be a reflection across the y-axis. I am great at visualizing but for those who are not (Not saying you) all they have to do is cut out a parallelogram and mimic the movements.

HELP PLSSSS I DONT UNDERSTAND WALLAH

Answer:

7.2

Step-by-step explanation:

Distance between (4, 3) and (8, 9):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(8 - 4)^2 + (9 - 3)^2}$

$d = \sqrt{(4)^2 + (6)^2}$

$d = \sqrt{16 + 36}$

$d = \sqrt{52} = 7.2$ (nearest tenth)

Answer:

perimeter ratio: 4 : 3
area ratio: 16 : 9

Step-by-step explanation:

The ratio of perimeters is the ratio of corresponding sides.

first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters

The ratio of areas is the square of the ratio of linear dimensions.

first : second = 4² : 3² = 16 : 9 . . . ratio of areas

The can of corn shown is a right circular cylinder with a height of 11 cm. The volume of the can is 486 cubic centimeters. What

hammer [34]

SOLUTION

Since the can is a cylinder, we will use the formula for volume of a cylinder to solve the problem.

Volume of a cylinder is given as

$\begin{gathered} V=\pi r^2h \\ where\text{ r = radius = ?} \\ h=height=11cm \\ V=volume=486cm^3 \end{gathered}$

Applying we have

$\begin{gathered} V=\pi r^2h \\ 486=3.14\times r^2\times11 \\ 486=34.54r^2 \\ r^2=\frac{486}{34.54} \\ r=\sqrt{14.07064} \\ r=3.75108 \end{gathered}$

Hence the answer is 3.8, the second option is the answer
