On a coordinate plane, parallelogram A B C D has points (3, 6), (6, 5), (5, 1), and (2, 2).What is the area of parallelogram ABCD?

Answers

Answer 1

Answer:

Answer: The area is about 13.01.

Step-by-step explanation:

so to do this we need to find the distance between these points.And we do that by using the Pythagorean rule a^2 + b^2=C^2

(3,6) and (6,5)

3^2 + 1^2 = c^2

c= $√(10)$

(6,5) and (5,1)

1^2 + 4^2= $√(17)$

$√(10) * √(17)$ = 13.038

Lane is 10 times Mel's age. If the difference in their age is 27, how old is Mel?

Answers

l - Lane's age
m- Mel's age.
Lane is 10 times Mel's age, so 10m = l
difference in their age is 27 so l - m = 27
Substitute l = 10m and you'll have:
10m - m = 27
9m = 27 /:9
m=3
And l = 10m = 10*3 = 30

So Lane has 3 years old and Mel has 30 years old.

An angle of an isosceles triangke is 28 degrees. What are the other 2 angles( choose all that apply)

Answers

Hey there!!

Remember :- In an isosceles triangle, two angles and two sides are equal. And the total sum of all the angles in a triangle is 180 degrees.

One angle of the isosceles triangle is 28°

Let's take the other two angles as ' x '

As the total sum = 180°, let's get this into equation

28 + x + x = 180

28 + 2x = 180

2x = 180 -28

2x = 152

x = 76°

Hence, the angles in the triangle are as follows:

28° , 76° and 76°

Henri bought 3 jars of spaghetti sauce. He used a coupon that reduced the cost of each jar by $0.75. If he paid $6.72 altogether, what was the regular price?

Answers

Answer: $8.97

Step-by-step explanation:

he bought three jars and lowered the price by 75 cents for each, so multiply $0.75 by three

$0.75 * 3 = $2.25

so henri saved $2.25 in total

we can add that to what he paid to find the original cost

$6.72 + $2.25 = $8.97

so the original price was $8.97 :)
