Answer:
Each table gets 4 napkins
Step-by-step explanation:
Rate of change
It usually refers to how fast one quantity changes with respect to another. We are given the following information.
After putting napkins on 6 tables, Howard has 124 napkins remaining
After putting napkins on 10 tables, Howard has 108 napkins remaining
This means that Howard used 124-108=16 napkins in 10-6=4 tables.
The rate of change (or rate of use in this case) is 16 napkins/4 tables= 4 napkins per table.
Each table gets 4 napkins
Find the perimeter in simplest form and explain your work
9514 1404 393
Answer:
7 1/8 yd
Step-by-step explanation:
The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.
P = 3·(2 3/8 yd) = 6 9/8 yd . . . . . 9/8 = 1 1/8
P = 7 1/8 yd
The perimeter is 7 1/8 yards.
Answer:
[tex]perimeter \: of \: the \: triangle \\ = 2 \frac{3}{8} +2\frac{3}{8} + 2 \frac{3}{8} \\ = 3 \times 2 \frac{3}{8}\\= 3 \times \frac{19}{8} \\ = \frac{57}{8} \: yd \\ = 7 \frac{1}{8} \: yd[/tex]
57/8 yards is the right answer.Walking Robert walks 7 blocks east from his home and arrives at his favorite restaurant. When he arrives, he discovers that he dropped his wallet along the way. He retraces his steps for 5 blocks until he finds his wallet. An expression for how many blocks east Robert is from his home after finding his wallet is the sum 7+(−5).
Answer:
2 block east from home
Step-by-step explanation:
Given an expression for how many blocks east Robert is from his home after finding his wallet as the sum 7+(−5),
Simplifying the given expression
7+(-5) = 7-5 (note that the product of a plus and minus sign will give a minus sign)
7-5 = 2
Hence Robert will be 2 block east from home

The formula for the volume of a sphere is V space equals space 4 over 3 Ïr cubed. Find the radius to the nearest hundredth of a sphere with each volume. 20 ft 3 i really need to know the answer
Answer:
r = 1.68 ft
Step-by-step explanation:
Volume of a sphere, V = 4/3πr³
V = 20 ft³
π = 3.14
r = ?
V = 4/3πr³
20 = 4/3 × 3.14 × r³
20 = (4×3.14×r³)/3
Cross product
20 × 3 = 4 × 3.14 × r³
60 = 12.56r³
r³ = 60/12.56
= 4.7771
r = 3√4.7771
= 1.6842
Approximately
r = 1.68 ft to the nearest hundredth

Laura walked 6 1/2 laps of a circular path in 2 hours. At that rate, how many laps of the path did she walk in one hour
Answer:
3 1/4
Step-by-step explanation:
Laura walked 6 1/2 laps of a circular path in 2 hours. At that rate, she walk circular path in one hour is, 3 1/4 laps.
What is rate?Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.
So formula for the rate is,
m = change in one quantity/change in another quantity = Δy/Δx
Given that,
Laura walked 6 1/2 laps of a circular path in 2 hours,
Suppose, she walked at constant speed
So, we can say that
Whatever, distance she walked in 2 hour that will be double of the distance she walked in 1 hour,
Therefore, laps of the path she did walk in one hour is (13/2)/2 =13/4
Hence, laps she walked is 3 1/4

A.2.4 units
B.4.8 units
C.13.6 units
D.14.4 units
Answer= C
Answer:
2.24units
Step-by-step explanation:
Let the coordinate be A(3, -5) and A'(2, -3)
Using the formula for calculating the distance between two points
D = √(x2-x1)²+(y2-y1)²
AA' = √(2-3)²+(-3-(-5))²
AA' = √(-1)²+(-3+5))²
AA' = √1+2²
AA' =√5
AA' = 2.24 units

Answer:
93 Sq.ft
Step-by-step explanation:
Formula for total surface area of a cylinder is;
TSA = 2πr² + 2πrh
In the question, we have Half cylinder, thus; TSA for half cylinder is;
TSA_½ = (2πr² + 2πrh)/2
TSA_½ = πr² + πrh
r = 3/2 = 1.5 ft
h = 5 ft
Thus;
TSA_½ = π(1.5)² + π(1.5 × 5)
TSA_½ = 30.63 Sq.ft
Surface area of rectangular prism is;
SA = 2(lw + lh + wh)
We have;
l = 5 ft
h = 2 ft
w = 3 ft
Thus;
SA = 2((5 × 3) + (5 × 2) + (2 × 3))
SA = 2(15 + 10 + 6)
SA = 62 Sq.ft
Thus, surface area of treasury is;
S.A_t = TSA_½ + SA
S.A_t = 30.63 + 62
S.A_t = 92.63 approximately 93 Sq.ft

O $2; the cost per order
$15; the cost per order
Answer:
:)
Step-by-step explanation:
It should be $2; the cost per muffin
The cost of one muffin is $2.
What is subtraction?Subtraction is mathematic operation. Which is used to remove terms or objects in expression.
Given, $15 is delivery cost of muffins.
That means the if x is the cost of one muffin then
Total cost = nx + $15
,where n is the number of muffins.
Now,
for n = 1
The total cost of one muffin is :
17 = x + 15
x = 2
Therefore, the cost of one muffin is $2.
