A. 54 cm^2
B. 90 cm^2
C. 108 cm^2
D. 216 cm^2
What is the area of the triangle? A = [tex]\frac{bh}{2}[/tex] - 1

Answers

Answer 1
Answer:

Answer:

A = 54cm^2

Step-by-step explanation:

A = (base × height)/2

base = 9cm

height= 12cm

A = (9 × 12)/2

A = 108/2

A = 54

3,200 oz = __________lb

Answers

There are 16 ounces in 1 pound, so all we need to do to find out how many pounds are in a certain amount of ounces is divide the amount of ounces by 16.

3200 / 16 = 200

3,200 oz = 200 lbs
Hope that helped =)
So,

First, the conversion between ounces and pounds is:
16 oz. = 1 lb.

So:
3200 (16 * 200) oz. = 200 lbs.

Find the distance, to the nearest tenth, from T(4,-2) to U(-2,3).

Answers

Answer:

7.81

Step-by-step explanation:

Using the formula for finding the distance between two points as shown:

TU = √(y2-y1)²+(x2-x1)²

Given T = (4,-2) and U = (-2,3)

x1 =4, y1 = -2, x2 = -2, y2 = 3

Substituting this values into the formula, we have;

TU = √{3-(-2)}²+(-2-4)²

TU = √(3+2)²+(-2-4)²

TU = √5²+(-6)²

TU = √25+36

TU = √61

TU = 7.81

The distance between the two points is 7.81
d = \sqrt{ (x_(1) - x_(2))^(2) + (y_(1) - y_(2))^(2) } \n d = \sqrt{ (4 - (-2))^(2) + (-2 - 3)^(2) } \n d = \sqrt{ (6)^(2) + (-5)^(2) } \n d = √( 36 + 25) \n d = √( 61 ) \n d = 7.81024... \n d = 7.8

Answers

(-7)/(12) = (y)/(-36)

First, simplify (y)/(-36) to - (y)/(36) / Your problem should look like: - (7)/(12) = -(y)/(36)
Second, multiply both sides by 36. / Your problem should look like: -21=-y
Third, multiply both sides by -1. / Your problem should look like: 21 = y
Fourth, switch your sides. / Your problem should look like: y = 21

Answer: C) 21

How can you use subtraction to complete an addition pattern?

Answers

if you have an equation like 3+x=6
then you use subtraction by subtracting 3 from 6 to get 3
thats how you get the value of x (x=3)
then you can go back and plug it in 3+3=6

Hope this helps!! :D
Hello! I Am going to show you an example. 3+3 = 6. 6-3 = 3
