Answer:

Connect points A and B. That makes a line parallel to the y-axis and perpendicular to the x-axis. Plot two more random points and write down their coordinates along with points A and B's coordinates. For number 5, it says that the point you need to write has to fall on line L with a y-coordinate greater than 20. Coordinates (x,y) y has to be greater than 20 and x has to be equal to 4. So (4, any number over 20) would work. For example: (x, 25) would be an appropriate answer to number 5. Hope this helps!

Find the are of a parallelogram that has a base of 7 1/2 and a height of 5 2/7

Amiraneli [1.4K]

Use the formula for the area of a parallelogram:

$\sf A=bh$

Plug in what we know:

$\sf A=(7\dfrac{1}{2})(5\dfrac{2}{7})$

Convert both of them into improper fractions. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes our new numerator, and we keep the denominator the same:

$\sf A=(\dfrac{15}{2})(\dfrac{37}{7})$

Now multiply the numerators and denominators together:

$\sf A=\dfrac{15}{2}\cdot\dfrac{37}{7}\rightarrow\dfrac{15\cdot 37}{2\cdot 7}\rightarrow\dfrac{555}{14}$

Convert it back into a mixed number. 14 goes into 555 thirty-nine times. 14 * 39 = 546. 555 - 546 = 9. So we have 39 wholes and 9 left over, or:

$\sf 39\dfrac{9}{14}$

So this is the area of the parallelogram.

What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?

JulijaS [17]

Answer:

0.571428571429 grams per cm³

Step-by-step explanation:

density = mass/volume

Let’s calculate the volume V of the pyramid :

V = (1/3)×base×height

= (1÷3)×(5×7)×9

= 105 cm³

Then

The density = mass/volume

= 60÷105

= 0.571428571429

A 2 liter bottle of Coke for $1.39 or a 12 pack of 12 ounce cans of Pepsi for $3.49. Which is the better deal?

RideAnS [48]

2 liters equals approximately 68 ounces, which costs about 6 cents per 12 ounces (cost per ounce is too small to document). The cost per a twelve ounce can is about 0.29 cents. The can is the better deal.
