In Little Kitty City, the tax rate is 7.25%. What would the tax be on a $500 TV? (Hint: Change 7.25% to a decimal by moving the decimal two spots to the left.
Answer:
Tax amount = $36.25
Step-by-step explanation:
The tax rate is 7.25%.
We need to find the tax be on a $500 TV.
It can be calculated as follows :
[tex]C=500\times 7.25\%\\\\=500\times \dfrac{7.25}{100}\\\\=\$36.25[/tex]
So, the required tax on $500 TV is $36.25.

Arianna and Hansen are hosting events that are catered by the same company. Arianna plans to have 65 adults and 56 children attend, so the total projected cost of her meals is $3,003. Hansen has 86 adults and 62 children on his guest list, so he will pay the caterer $3,816. How much does the caterer charge for each meal? Choose the correct system of equation given that A stands for adults and C stands for children.
Answer:
C = $13
A = $35
Step-by-step explanation:
The computation is shown below:
Let us assume the Adults be A
And children be C
So the first equation would be
65A + 56C = $3,003
And, the second equation is
86A + 62C = $3,816
Now multiply by 86 in equation 1 and 65 in equation 2
5,590A + 4,816C = $258,258
5,590A + 4,030C = $248,040
786C = 10,218
C = $13
And A is
65A + 56($13) = $3,003
65A + $728 = $3,003
65A = $3003 - $728
65A = $2,275
A = $35

Here are five number cards 2, 5, 7, 8,9. One of the cards is removed and the mean average of the remaining four number cards is 6. Which card was removed you must show your working out
Answer:
7
Step-by-step explanation: Trust me
Answer:
Calculate the average of the five original cards:
2+5+7+8+9=31
31/5 = 6.2
So, if a card was removed, the four remaining cards would have an average of 6, meaning that they would add up to 24.
31-x=24?
Subtract 31 from both sides: -x=-7
Divide by -1 on both sides: x=7
So, we know that 7 was removed.

circumference: 37.68 units

Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]
pls help Find the area of the shape shown below.
\text{ units}^2 units
2
Answer:
8 sq units
Step-by-step explanation:
area of square in middle is 2 x 2 = 4 sq units
area of one triangle is 1/2(2)(2) = 2 sq units
however, there are two triangles, so you have to double 2 to get 4
4 + 4 = 8
Answer:
8cm^2
Step-by-step explanation:
Method 1: It's a trapezium, so take the top length, (6cm), add it to the bottom length (2cm) = 8cm which is then divided by 2 (4cm) then multiplied by the height (2cm) giving an area of 8cm squared.
Method 2: area of the square = 2 x 2 = 4cm^2
Triangle 1: 2 x 2 = 4, divided by 2 = 2cm^2
Triangle 2: same as triangle 1.
Total: 4 + 2 + 2 = 8cm^2
9. What is the range of the relation [(4, 2), (1, 1), (0, 0). (1.-1). (4, -2) ?
Answer:
{-2,-1,0,1,2}
Step-by-step explanation:
When we are talking of the range, we are referring to the possible y-values the relation can take
Hence, a set of y-values will represent the range of the relation
we have this as:
{2, 1 , 0, -1 , -2}
Arranging in order, we have ;
{-2,-1,0,1,2}
Exit Which algebraic expression below represents four multiplied by a number? A. 4 – x B. x + 4 C. 4x D.
Answer:
C. 4x
Step-by-step explanation:
Considering the options
A.4 – x - This is the difference between 4 and a number x
B. x + 4 - This is the sum of a number x and 4
C. 4x - This is the product of a number x and 4
D.
From the above, option C which is the product of x and 4 is same as four multiplied by a number.
If y = 2x + 1 and x = 4, then y =
Answer:
9
Step-by-step explanation:
First, plug-in 4 for x to get the equation y = 2(4) + 1
Then using PEMDAS we multiply 2 and 4 to get 8 and then add the one to make y = 9

Answer:
21a-14b
15b-20a
Step-by-step explanation:
Answer: a + 3b
Step-by-step explanation:
Okay, so...
7(3a - 2b) = 7(3a) - 7(2b) ... distributive property
21a - 14b
5(3b - 4a) = 5(3b) - 5(4a) ... distributive property
15b - 20a
(21a - 14b) + (15b - 20a) = 21a -12b + 15b - 20a =
a + 3b

Anita sells her ring at the price of Rp 540,000.00. If Anita gets If Anita gets the profit of 20%, then how much does Anita buy that ring ?
Answer:
selling price=Rp 540,000.00.
profit=20%
cost price=selling price- profit% of cost price
cost price+profit% of cost price=selling price
cost price (1+20%)=Rp 540,000.00.
cost price=Rp 540,000.00./(1+20/100)=Rp 450000.00 is your answer

3. At an ice cream parlor, ice cream cones cost $2.00 and sundaes cost $3.50. One day, the receipts for 114 cones and
sundaes total $301.50. How many cones and sundaes were sold? (Assume tax is included in the cost.)
Answer:
Number of ice cream cones = 65
Number of sundaes = 49
Step-by-step explanation:
Let
x = number of ice cream cones
y = number of sundaes
x + y = 114 (1)
2x + 3.5y = 301.50 (2)
From (1)
x = 114 - y
Substitute into (2)
2x + 3.5y = 301.50 (2)
2(114 - y) + 3.5y = 301.50
228 - 2y + 3.5y = 301.50
- 2y + 3.5y = 301.50 - 228
1.5y = 73.50
y = 73.50/1.5
y = 49
Substitute y = 49 into (1)
x + y = 114 (1)
x + 49 = 114
x = 114 - 49
x = 65
Number of ice cream cones = 65
Number of sundaes = 49
