Answer:
P = 64 meters
Step-by-step explanation:
P = 2(l+w) for a rectangle
Substitute in the length and the width
P = 2( 21+11)
P = 2( 32)
P = 64 meters
Answer:
P = 2(l+w)
= 2 ( 21+11)
= 2(32)
= 64m

A gift shop at an amusement park sells key chains. The gift shop has 55 key chains. When the number of key chains is below 10, the manager will reorder. If the gift shop sells 4 key chains each day, how many days will it take before the manager has to reorder?
Answer:
12
Step-by-step explanation:
this equation can be derived from the question
55 - 4x < 10
< = less than
x = number of days
solve for x
55 - 10 < 4x
45 < 4x
x < 11.25
at the 11th day, there would be 11 keys left
on the 12th day, there would be 7 keys left
the correct answer is 12 days
Solve 2x - 3y - 11 3x + 3y - 9 by elimination. Express your answer as an ordered pair.
Answer:
x= 4, y = -1
Step-by-step explanation:
2x-3y=11
3x+3y=9
do addition and you should get
5x=20
x=4
plug in x into any equation
12+3y=9
3y= -3
y=-1
PLEASEEEE HELPPPPP PLEASEEEE
Answer/Step-by-step explanation:
A. The quadrilateral cam be named using the letters of the vertices. Thus, it is named as: quadrilateral LMNP
B. 82° + (3x - 1)° = 180° (adjacent angles are supplementary)
Solve for x
82 + 3x - 1 = 180
Add like terms
81 + 3x = 180
Subtract 81 from both sides
3x = 180 - 81
3x = 99
x = 99/3
x = 33
C. Opposite angles in a quadrilateral are equal. Therefore,
m<L = (3x - 1)°
Plug in the value of x
m<L = 3(33) - 1
m<L = 99 - 1
m<L = 98°

18-3×5+32÷4 (show with procedure fast..)
Answer:
18-3*5+32÷4
=18-3*5+8
=18-15+8
=26-15
=11
Step-by-step explanation:
use BODMAS rule
• 18- 3× 5+ 32÷ 4
= 18- 3× 5+ 8
= 18- 15+ 8
= 18+ 8- 15
= 26- 15
= 11
Hope it helps♡Help plz math question. EXPLAIN HOW YOU GOT THE ANSWER. 30 PTS btw thx if u help
Answer:
256
Step-by-step explanation:
4^4^4 = 4^(4^4) = 4^256
so written in base 4, there will be 256 zeroes after a 1.
This translates to approximately 154 digits in decimal.
Just like 2^2^2 = 2^4
there will be four zeroes after a 1.
2^2^2=2^(2^2) = 2^4 = 16 = 10000 (16 in base 2).
3. You owe $1,350.00 on a credit card with a 14.25% APR. You pay $300.00 at the beginning of
the month How much interest do you save by paying at the beginning of the month versus
at the end of the month?
Answer:
Step-by-step explanation:
As an aside, I don't know why Americans don't use a debit card. Usually to figure out what the monthly interest is, you divide the yearly interest by 12
14.25 / 12 = 1.875 and you keep all the decimals.
1350 * 1.875 / 100 = 16.03 is what you save, but there is more. It seems very tiny, but don't be fooled. The credit card company certainly isn't. They will likely round up to 16.04 just so hackers won't make anything if they break into someone's account.
16.04 doesn't seem like much to pay, but realize that if you had to pay it every month, it would be 192.48 a year. That on 1350 is usury.

Help!!! Whats x ive been struggling
Answer:
x = 2
Step-by-step explanation:
GIVEN :-
KJ = 3 unitsQR = 12 unitsJL = x unitsQS = x + 6 unitsTO FIND :-
The value of xSOLUTION :-
To find the value of x , lets assume that both the triangles are similar to each other. As they are similar , their sides are proportional to each other i.e. :-
[tex]\frac{KJ}{JL} = \frac{QR}{QS}[/tex]
[tex]=> \frac{3}{x} = \frac{12}{x + 6}[/tex]
Cross multiply the denominators.[tex]=> 3(x + 6) = 12 \times x[/tex]
[tex]=> 3x + 18 = 12x[/tex]
Substract both the sides from 3.[tex]=> 12x - 3x = 3x + 18 - 3x[/tex]
[tex]=> 9x = 18[/tex]
Divide both the sides by 9[tex]=> \frac{9x}{9} = \frac{18}{9}[/tex]
[tex]=> x = 2[/tex]

Ruby is ordering some pizza! She has to pay for the cost of the pizza plus the cost of the delivery fee(cost per minute that it takes a the delivery driver to get to her house). The pizza cost $12, and it took 10 minutes for the delivery driver to get there. In total, she has to pay $15
Answer:
Delivery cost per minute = $0.3 per minute
Step-by-step explanation:
Given:
Cost of pizza = $12
Total amount pay by Ruby = $15
Time taken for delivery = 10 minutes
Find:
Delivery cost per minute
Computation:
Total amount of delivery = Total amount pay by Ruby - Cost of pizza
Total amount of delivery = 15 - 12
Total amount of delivery = $3
Delivery cost per minute = Total amount of delivery / Time taken for delivery
Delivery cost per minute = 3 / 10
Delivery cost per minute = $0.3 per minute
We can use the formula density mass over volume to find the density of a substance square metal plate has a density of 10.7 g of per cubic centimeters and a mass of 23.54 g calculate the volume
Answer: The volume of given substance is [tex]2.2 cm^{3}[/tex].
Step-by-step explanation:
Given: Density = 10.7 [tex]g/cm^{3}[/tex]
Mass = 23.54 g
Density of a substance is the mass of substance divided by its volume.
Mathematically, [tex]Density = \frac{mass}{volume}[/tex]
Substitute the values into above formula to calculate volume as follows.
[tex]Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}[/tex]
Thus, we can conclude that the volume of given substance is [tex]2.2 cm^{3}[/tex].

find the missing length of the triangle
Answer:
B) 28 in
Step-by-step explanation:
Pythagorean thm formula:
a² + b² = c²
Given:
b = 45
c = 53
Work:
a² + b² = c²
a² + 45² = 53²
a² + 2025 = 2809
a² = 2809 - 2025
a² = 784
[tex]\sqrt{a^2} =\sqrt{784}[/tex]
a = 28
