Answer:
4x + 6 feet
Step-by-step explanation:
The deck is the shape of a rectangle
Hence, the perimeter of a rectangle is:
P = 2L + 2W
Where
L = Length = x feet
The width of the deck was 3 feet longer than the length.
W = Width = 3 + x feet
Hence:
Perimeter = 2(x ) + 2(3 + x)
Perimeter = 2x + 6 + 2x
Perimeter = 4x + 6 feet
Hence, the expression for the Perimeter of the deck is given as:
4x + 6 feet

Bradley Wiggins cycles 2.5km on a warm up. If the diameter of Bradley's bike wheel is 68cm, how many times (to the nearest whole rotation) will Bradley's bike wheel have rotated on this journey?
Answer:
1171 rotations
Step-by-step explanation:
Given that:
Distance cycled = 2.5km
Diameter of bike wheel, d = 68cm = 0.68m
We obtain the Circumference of the bike wheel:
Circumference, C = πd
C = 3.14 * 0.68
C = 2.1352 m
The number of rotations Bradley's wheel will make will be :
Total distance cycled / Circumference
= (2.5 *1000)m / 2.1352m
= 2500 / 2.1352
= 1170.8505
= 1171 rotations

Answer:
28 8/21
Step-by-step explanation:
18 5/7 + 9 2/3 (hint: remember you have to turn them into common denominators)
so ther least common denominator would be 21 so...
18 15/21 + 9 14/21
then add it together
28 8/21
Answer:
I got 28 8/21. There's a picture of how I did it.
Step-by-step explanation:
I used a method called the butterfly method. I did 18 + 9 which equals 27. Then I did 5/7 + 2/3 and got 29/21, and divided the fraction and got 28 8/21.

A meal costs $20 before tax and tip.
There is a 8% sales tax. After the tax, a 15% tip is
added.
What is the total after tax and tip?
Answer:
24.84$
Step-by-step explanation:
You multiply 20 by 0.08 which equals 1.6
then you add 20 + 1.6 which equals 21.6
then you multiply 21.6 by 0.15 which equals 3.24
24.84

The answer is the last one: The slop of the line is 1/4, so the company charges $0.25 per mile.
Step-by-step explanation:
The slope is 1/4 because you rise 1 and run 4 putting the point at (4,1)
$0.25 because to go 4 miles it is one dollar so 1 mile is $0.25

Angles and Lines
The figure attached below has been completed with the angle y to support the calculations to come.
The sum of the interior angles of a rectangle is 180°. Applying on triangle PQR:
30 + 4x + 2 + y = 180
Simplifying:
32 + 4x + y = 180
Solving for y:
y = 180 - 32 - 4x
y = 148 - 4x
Angles y and 8 + 6x are a linear pair, i.e. their sum is 180°, thus:
y + 8 + 6x = 180
Substituting y from the equation above:
148 - 4x + 8 + 6x = 180
Simplifying:
156 + 2x = 180
Dividing by 2:
78 + x = 90
Subtracting 78:
x = 90 - 78
x = 12

A family prepares an emergency kit for their home. The kit contains 63 gallons of drinking water. The family's daily drinking water needs are 3 1/2 gallons for the adults and 1 3/4 gallons for the children. For how many days would this emergency water supply last the family
Answer:
12 days
Step-by-step explanation:
Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults
3[tex]\frac{1}{2}[/tex] + 1[tex]\frac{3}{4}[/tex] =
Converting to decimals
3.5 + 1.75 = 5.25 = 5[tex]\frac{1}{4}[/tex]
If there are 63 gallons, the water supply would last for :
63 / 5.25 =12 days
Answer: 12 days
Step-by-step explanation: They have 63 gallons, they are using approximately 5.25 per day, so if you divide you will get 12 days

Triangle ABC is similar to triangle DEF
Answer:
A my dude. good luck!!!!!
Answer:
A
Step-by-step explanation:
AC = 5
DF = 15
5 x 3 = 15
BC = 3
EF = 9
3 x 3 = 9
Do you see the pattern? So as you can see the difference between Triangle ABC and DEF is the multiply/divide 3 so if you want to find DE then you should set it up as:
[tex]\frac{4}{3}[/tex] = [tex]\frac{DE}{9}[/tex] and to check if its right if you solve it you get [tex]\frac{4}{3}[/tex] = [tex]\frac{12}{9}[/tex]
and as you see [tex]\frac{12}{9}[/tex] and [tex]\frac{4}{3}[/tex] are literally the same thing just you need to simplify [tex]\frac{12}{9}[/tex]
