Answers

Lots of "ifs" here.

A=bh/2 is the formula for the area of a triangle.

A=bh is the formula for the area of a rectangle or a parallelogram.

If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2

If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2

Help, how do i do this problem and I really need this

Answers

Okay, so one of the geometric theorems is that two of the inside angles equals the outside angle in a situation like this one.

So, set them equal:
2x+ 2 + 4x + 8 = 8x - 30

Combine like terms:
6x + 10 = 8x - 30

40 = 2x

x = 20

You would need to sell 28 bracelets.

q(x)=12x−3; q(x)=−4

Answers

Answer:

x = -1/12

Step-by-step explanation:

q(x) = 12x − 3

q(x) = −4

-4 = 12x − 3

12x - 3 = -4

12x = -4 + 3

12x = -1

x = -1/12

A+B=44
A : B is equvililent to 13 :8
Please solve

Answers

Step-by-step explanation:

13:8A=13x. B=8x13x + 8x = 44 21x=44 x=2.095
13:18 is in simplest form, so it’s multiplied by something, let’s call it x

So A + B equals 13x + 8x

13x + 8x = 44
21x = 44
x =44/21

Plug in to check:
13(44/21) + 8(44/21) = 44
572/21 + 352/21 = 44
924/21 = 44
44 = 44 :)

Complementary angles form a right angle. The sum of complementary angles is 90°

Step-by-step explanation:

A die has 6 faces with numbers 1, 2, 3, 4, 5, 6.

The faces that are less than 3 are 1, 2.

2 faces have numbers less than 2.

The desired outcome can happen 2 ways, 1 or 2.

The total number of possible outcomes is 6: 1, 2, 3, 4, 5, or 6.

p(event) = (number of desired outcomes)/(total number of possible outcomes)

p(less than 3) = 2/6 = 1/3

The probability of rolling a number less than 3 is 1/3.

Now we find 1/3 of 420.

1/3 * 420 = 420/3 = 140

Answer:

AB=10

AB=7.2

Step-by-step explanation:

AB= √{(9-1)²+(8-2)²} = √{8²+6²}=√{64+36}=√100 =10

AB= √{(6-2)²+(2-8)²} = √{4²+(-6)²}=√{16+36}=√52 =7.2

What is a coordinate plane ?

A coordinate plane is a plane in which a set of two number lines are represented, horizontal line is called x-axis and vertical line is called y-axis.

In the first coordinate plane,

The coordinate of point A is (1, 2) and coordinate of point B is (9,8),

To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]

Thd distance between A(1, 2) and B(9,8),

AB= [tex]\sqrt{{(9-1)^2+(8-2)^2}}[/tex] = [tex]\sqrt{{8^2+6^2}}[/tex]=[tex]\sqrt{{64+36}}[/tex]=[tex]\sqrt{100}[/tex] =10

In the second coordinate plane,

The coordinate of point A is (2, 6) and coordinate of point B is (8, 2),

To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]

The distance between A(2, 6) and B(8, 2),

AB= [tex]\sqrt{{(8-2)^2+(2-6)^2} }[/tex]= [tex]\sqrt{6^2+(-4)^2}}[/tex]=[tex]\sqrt{{36+16}}[/tex]=[tex]\sqrt{52}[/tex] =7.2
