Step-by-step explanation:
top left triangle - base is 3 because (20-8-9). so 1/2 bh = 1/2 (3) (6) = 9
left rectangle = l x w = 20 x 6 = 120
middle square = l x w = 8 x 9 = 72
lower right triangle = height is 12 because (26-8-6), so 1/2 bh =1/2 (9)(12) = 54

Answers
Answer: 10 cups of flour
Step-by-step explanation:
15 1/2 cups of flour = 7 1/2 cups
7 1/2 ÷ 3 = 2 1/2
So, it takes 2 1/2 cups of flour to make one loaf of bread
If you want to make 4 loaves of bread, you multiply 2 1/2 × 4
2 1/2 × 4 = 10
It will take 10 cups of flour to make 4 loaves of bread.
Solve the following equation for x.
6x = 1.5
Answers
Answer:
x = .25
Step-by-step explanation:
6x = 1.5
Divide each side by 6
6x/6 = 1.5/6
Multiply the top and bottom by 10
x = 1.5*10/ (6*10)
x = 15/60
x = 1/4
x = .25
work: 6x= 1.5
6x/6 = 1.5/6
simplify = 6 divided by 6 = 0
1.5 divided by 6 = 0.25
0.25 is the answer

O E. : 13
O F. 13:3
Answers
Answer:
Step-by-step explanation:
we know that
In a triangle
the ratio between the lengths of the two legs is equal to the tangent
so
therefore
the answer is
Option B
-------> could be the ratio
because is the value of the
Option C
------> could be the ratio
because is the value of the
Option E
-------> could be the ratio
because is the value of the
The options B, C and E giving the ratios are correct.
What are ratios?Ratio, in math, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Given that, a 30-60-90 right triangle, we need to find the ratio between the lengths of the two legs of the triangle,
Since, we know that,
In a right triangle, the ratio between the lengths of the two legs is equal to the tangent.
so,
Tan 30° = 1/√3
Also,
√3 / 3 = 1/√3
3/3√3 = 1/√3
Hence, the options B, C and E giving the ratios are correct.

find the equation of the line use exact numbers
Answers
Answer:
y = -³/2x + 3
Step-by-step explanation:
To find the equation of the line in slope-intercept form, y = mx + b, we need to finder the slope (m) and the y-intercept (b).
✔️Slope (m) = ∆y/∆x
Using two points on the line, (0, 3) and (2, 0),
Slope = (0 - 3)/(2 - 0) = -3/2
Slope (m) = -³/2
✔️y-intercept (b) = 3 (this is the y-cooordinate of the point where the line intercepts the y-axis)
✔️To write the equation, substitute m = -³/2 and b = 3 into y = mx + b
This:
y = -³/2x + 3

A 32 ft board is cut into three pieces at a sawmill. The second piece is 5 ft longer than the first and the third piece is 1 ft longer than the second.
What are the lengths of the three pieces?
Answers
Answer:
The first piece is 7 ft long, the second piece is 12 ft long, and the third piece is 13 ft long
Step-by-step explanation:
Let x represent the length of the first piece.
Since the second piece is 5 ft longer than the first, it can be represented by x + 5
Since the third piece is 1 ft longer than the second, it can be represented by x + 6
Create an equation that adds all of these terms up to 32, and solve for x
(x) + (x + 5) + (x + 6) = 32
3x + 11 = 32
3x = 21
x = 7
So, the first piece is 7 ft long.
Using the expressions we created, solve for the lengths of the second and third pieces.
x + 5
7 + 5 = 12
x + 6
7 + 6 = 13
The first piece is 7 ft long, the second piece is 12 ft long, and the third piece is 13 ft long

What do you mean by the term Angle ?
An angle is a geometric figure formed by two rays or lines that share a common endpoint, called the vertex. The rays or lines are called the sides of the angle, and they can be measured in degrees or radians.
An angle can be classified as acute, right, obtuse, or straight, depending on its measure. An acute angle is less than 90 degrees, a right angle is exactly 90 degrees, an obtuse angle is greater than 90 degrees but less than 180 degrees, and a straight angle is exactly 180 degrees.
According to question
In ΔABC ,
∠ C is 100°
So,the value of x is also 100°( by vertically opposite angle)
