Hannah needs two 2/3 -footboards and one 1 1/2-footboard for a woodshop project. For each question below, write your answer as a mixed number in the simplest form and show all work needed to support your answer.
• What is the total length of board that Hannah needs?
• If Hannah cuts the pieces she needs from a 6-foot board, what is the length of the board that will be leftover?
• How many woodshop projects can Hannah make from a 6-foot board?
Answers
Answer:
total length: 2 1/6 ft Leftover: 4 5/6 ft How many: 2
Step-by-step explanation:
Total length: add 2/3ft and 1 1/2 ft together.
Leftover: Subtract 2 1/6ft from 6ft
How many: Multiply 2 1/6 by 2
Answer:
What is the total length of board that Hannah needs? 2 5/6 foot board

Lisa is working on plans for a 12-acre housing development. A park will [tex]2\frac{1}{2}[/tex] cover acres, and paved areas will take [tex]1\frac{3}{4}[/tex] acres. How many acres are left for home sites.
Answers
Answer:
Step-by-step explanation:
Here is the equation for this problem:
2 1/2 + 1 3/4 + x = 12
To add 2 1/2 and 1 3/4, revert the fractions into mixed numbers, and then change the denominator to the LCM (Lowest Common Denominator)
3/2 + 7/4 + x = 12
The lowest common denominator, in this case, is 4. 7/4 stays the same because the denominator is already 4, but we need to multiply the numerator and denominator of 3/2 by two to get the denominator to 4. (Whatever you do to the numerator, you have to do to the denominator, and vice versa)
3 x 2 = 6
2 x 2 = 4
Now, the equation looks like this:
6/4 + 7/4 + x = 12
Now add the fractions. The denominator stays the same, but the numerators are added together.
6/4 + 7/4 = 13/4
Now, you can revert 13/4 back to a mixed number
13/4 = 3 1/4
The equation should look like this now:
3 1/4 + x = 12
Now subtract 3 1/4 from both sides (Meaning subtract 3 1/4 from 3 1/4 to cancel it out and also subtract 3 1/4 from 12 as well)
12 - 3 1/4 = 8 3/4
Now, it should look like this:
x = 8 3/4
You could change the 8 3/4 into a decimal as well, which would look like this:
x = 8.75
Here is a summary of the whole equation:
2 1/2 + 1 3/4 + x = 12
3/2 + 7/4 + x = 12
6/4 + 7/4 + x = 12
13/4 + x = 12
3 1/4 (-3 1/4) + x = 12 (-3 1/4)
x = 8 3/4 or 8.75 acres
Answer:
Lisa has 8 3/4 acres left for home sites
There will be 7.75 acres of land left for home sites.
What is Mixed Fraction?Mixed fractions are type of fractions which includes both a whole part and a fractional part.
It is of the form a [tex]\frac{b}{c}[/tex], where a is the whole part and b/c is the fractional part. This actually implies that a + [tex]\frac{b}{c}[/tex]. So we can do the cross multiplication to change the mixed fraction into improper fraction.
Total land for housing development = 12 acres
Land covered by park = 2 [tex]\frac{1}{2}[/tex]
= (2 × 2 + 1) / 2
= 5/2 acres
Land covered by paved areas = 1 [tex]\frac{3}{4}[/tex]
= (1 × 4 + 3) / 4
= 7/4 acres
Total land covered by park and paved areas = [tex]\frac{5}{2}[/tex] + [tex]\frac{7}{4}[/tex]
= [tex]\frac{10}{4}[/tex] + [tex]\frac{7}{4}[/tex]
= [tex]\frac{17}{4}[/tex]
= 4.25 acres
So the remaining land = 12 - ([tex]\frac{5}{2}[/tex] + [tex]\frac{7}{4}[/tex])
= 12 - 4.25
= 7.75 acres
Hence Lisa can build the home sites in the remaining 7.75 acres of land.

Answer:
7.) 53.38
8.) 18.84
9.) 87.92
Step-by-step explanation:
7.)
For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.
The formula for finding the circumference is 2 × π × 8.5
2 × 3.14(π) = 6.28.
6.28 × 8.5 = 53.38
8.)
For the second question, we can see that the radius is now given to us which is 3ft.
The formula for finding the circumference is 2 × π × 3
2 × 3.14(π) = 6.28.
6.28 × 3 = 18.84
9.)
For the third question the raduis is also given to us, which is 14 in.
The formula for finding the circumference is 2 × π × 14.
2 × 3.14(π) = 6.28.
6.28 × 14 = 87.92

What is rigid transformation?A rigid transformation or an isometry is a transformation that does not change the sides and angle of plane figures.
What are the three types of rigid transformation?The three types of rigid transformation are:
1) Translation
2) Reflection
3) Rotation
According to the given question.
Triangle ABC is transformed to triangle DBE.
(a) Rotation rigid transformation can be used to map triangle ABC on to triangle DBE. If we rotate triangle ABC at 180 in clockwise direction the triangle ABC maps on to triangle DBE. ( A rotation is followed by another rotation).
(b) The angles ACB, BAC, ABC of given image are equals to the angles of preimage BED, BDE and EBD respectively. That is
ACB=BED
BAC=BDE, and
ABC=EBD
