Step-by-step explanation:
find the perimeter & area of the rectangle
Answer:
Perimeter = [tex]34\sqrt{2}[/tex] feet
Area = 60 feet²
Step-by-step explanation:
Let us revise the rules of perimeter and area of a rectangle
Perimeter = 2(Length + width)Area = Length × Width→ From the given figure
∵ The length = [tex]\sqrt{8}[/tex] feet
∵ The width = 5[tex]\sqrt{18}[/tex] feet
→ Simplify the roots
∵ [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]
∴ [tex]\sqrt{8}=2\sqrt{2}[/tex]
∴ The length = [tex]2\sqrt{2}[/tex] feet
∵ [tex]5\sqrt{18}=5\sqrt{(3)(3)(2)}[/tex]
∴ [tex]5\sqrt{18}=5(3)\sqrt{2}=15\sqrt{2}[/tex]
∴ The width = [tex]15\sqrt{2}[/tex] feet
→ Perimeter = 2(Length + width)
∵ Perimeter = [tex]2[2\sqrt{2}+15\sqrt{2}][/tex]
∴ Perimeter = [tex]2[17\sqrt{2}][/tex]
∴ Perimeter = [tex]34\sqrt{2}[/tex] feet
→ Area = Length × Width
∵ Area = [tex]2\sqrt{2}[/tex] × [tex]15\sqrt{2}[/tex]
∴ Area = [tex](2)(15)(\sqrt{2})(\sqrt{2})=(30)(2)=60[/tex]
∴ Area = 60 feet²

Logan and Nathan are shelving books at a public library. Logan shelves 5 books at a time, whereas Nathan shelves 6 books at a time. If they end up shelving the same number of books, what is the smallest number of books each could have shelved?
Answer:
30
Step-by-step explanation:
Given that
Logan shelves 5 books and
Nathan shelves 6 books
They end shelving the same number of books.
To find:
Smallest number of books each could have shelved?
Solution:
First of all, let us have a look at the definition of Least Common Multiple(LCM) of two numbers.
Least Common Multiple (LCM) of two numbers is the minimum number which is divisible by both the numbers.
Now, looking at the statement of the given question.
We have to find the LCM of both the numbers actually.
Making factors of the numbers:
[tex]5=5\times 1[/tex]
[tex]6=2\times 3[/tex]
Nothing is common here, therefore the LCM is [tex]5\times 6 =\bold{30}[/tex].
Smallest number of books shelved = 30

Answer: you keep adding 2 and 1/3 to get your answer. 18 day so the dog food should last up to 18days hope this helps
Dont take my word not 100% sure
The perimeter of a rectangle is 42 cm. The length is 3 cm greater than the width. Find the width and length
Answer:
width:9
length: 12
Step-by-step explanation:
width: substitute for x
length: since the length is 3 cm greater than the width, we substitute it for x+3.
we know that you need to add all the lengths to find the perimeter, and we know that the perimeter of the rectangle is 42 cm, so our equation is formed.
x+x+x+3+x+3=42
4x+6=42
4x=36
x=9
width:9
length:9+3=12

Step-by-step explanation:
The angles of a quadrilateral are in the ratio 1:2:3:4. Find the measure of each angle
Step-by-step explanation:
Since, the angles of the quadrilateral are in the ratio 1:2:3:4
Therefore, let their measures be x, 2x, 3x and 4x
By angle sum property of the interior angles of a quadrilateral.
[tex]x + 2x + 3x + 4x = 360 \degree \\ \\ 10x = 360 \degree \\ \\ x = \frac{360}{10} \\ \\ x = 36 \\ \\ \implies \: \\ 2x = 2 \times 36 = 72 \degree \\ \\ 3x = 3 \times 26 = 78 \degree \\ \\ 4x = 4 \times 36 = 144 \degree[/tex]
Manuel wants to go snowboarding with his friends. The closest ski and snowboard resort is approximately 20 miles west and 50 miles north from his house. Manuel picks up his friend who lives 15 miles south and 10 miles east of Manuel's house. How far are the two boys from the resort
Answer:
Step-by-step explanation:
First we need to calculate the displacement of the resort from Manuel's house using Pythagoras theorem.
S1 = √50²+20²
S1 = √2500+400
S1 = √2900
S1 = 53.85m
Next is to calculate the displacement of Manuel's friend house to Manuel's house.
S2 = √15²+10²
S2 = √225+100
S2 = √325
S2 = 18.03m
The displacement of the two boys from the resort will be ∆S = S2-S1
∆S = 53.84-18.03
∆S = 35.81m

Carla traveled 320 miles in 5 hours. At this rate, how far will Carla travel in 7 hours?
Answer:
448 miles
Step-by-step explanation:
If 5 hours = 320 miles
then 7 hours = ?
7 hours will give more so if more less divide
7hours ÷5hours × 320 miles
hours will cancel out
= 7÷5×320 miles
= 448 miles
Hence,Carla will travel 448 miles in 7 hours

Which of the following is true about a linear pair?
The two angles must be supplementary and adjacent to form a linear pair.
The two angles must be supplementary and adjacent to form a linear pair.
Any two adjacent angles form a linear pair.
Any two adjacent angles form a linear pair.
Any two supplementary angles are a linear pair.
Any two supplementary angles are a linear pair.
Vertical angles can form a linear pair.
Answer:
2
Step-by-step explanation:
;\
Answer: Choice A
The two angles must be supplementary and adjacent to form a linear pair.
Adjacent angles are angles that touch and share a common line segment, line, or ray. Think of two rooms that share the same wall and how they are considered adjacent rooms.
Supplementary angles form a straight angle. They add to 180 degrees.

Every day, Ann goes to the gym for 30 minutes and Max goes for 3 times longer. For how long does Max go to the gym every day?
To find this answer, it says that Max goes to the gym 3x longer than Ann. Ann only goes to the gym for 30 minutes.
Multiply the time that Ann goes by 3 to find the time that Max goes.
30 x 3 = 90
Which means, that Max spends 90 minutes at the gym. /
(To simplify, he goes to the gym for 1 hour and 30 minutes)
