A piggy bank contains $5.60 in nickels and dimes. The number of nickels is 8 less than 3 times the dimes. How many nickels and dimes are there in the piggy bank?
The piggy bank has nickels and dimes.
Answer:
64 nickels and 24 dimes are there in the piggy bank.
Step-by-step explanation:
There are $5.60 in the piggy bank in nickels and dimes.
Let x number of nickels and y number of dimes are there.
Now, 1 nickel ≡ 0.05 dollars and 1 dime ≡ 0.1 dollars.
So, 0.05x + 0.1y = 5.6
⇒ 5x + 10y = 560
⇒ x + 2y = 112 ....... (1)
Again, from the condition given we can write that,
So, 3y - 8 = x ........ (2)
Now, solving (1) and (2) we get 3y - 8 + 2y = 112
⇒ 5y = 120
⇒ y = 24
And from equation (2) we get x = 3y - 8 = 64.
So, there are 64 nickels and 24 dimes in the piggy bank. (Answer)
Answer:
64 nickels and 24 dimes in the piggy bank.

What is the approximate area of sector TSV?
Round the answer to the nearest tenth.
A. 3.1 m^2
B. 2.3 m^2
C. 1.1 m^2
D. 0.5 m^2
Answer:
C) The area of the sector TSV = 1.1 sq m.
Step-by-step explanation:
Here, the angle subtended by TSV at the center of the circle = 3 radians.
1 Radians = 57.2958°
So, 3 radians = 3 x 57.2958 = 171.887 °
⇒The angle of the sector TSV = 171.887 °
Now, the angle of any sector of a circle with angle Ф at the center
= [tex]\frac{\theta}{360} \times \pi \times (r^2)[/tex]
Here, r = 0.87 m
So, the area of the sector TSV = [tex]\frac{171.887}{360} \times \frac{22}{7} \times (0.87)^2 = 1.1358[/tex]
or, the area of the sector TSV = 1.13 sq m.
Now, rounding off the area to the nearest tenth ,we get:
The area of the sector TSV = 1.1 sq m.

What is the perimeter of a rectangle with a length of 9 - 2y and width of 7?
Answer:
The perimeter of the rectangle is 32 - 4y
Step-by-step explanation:
To find the perimeter, we will simply follow the steps below;
First write down the formula for finding the perimeter of a rectangle
The formula for finding perimeter in a rectangle is;
perimeter = 2l +2w
where l= length of the rectangle and w is equal to width of the rectangle
From the question given, length =9 - 2y and width =7
We can now proceed to insert the values into the formula;
perimeter = 2l +2w
=2(9-2y) + 2(7)
Then we will now simplify
perimeter =2(9-2y) + 2(7)
=18 - 4y + 14
= 18 + 14 - 4y
=32 - 4y
Therefore, the perimeter of the rectangle is 32 - 4y
The perimeter of the rectangle is 32-4y.
Step-by-step explanation:
Given information:
The length of the rectangle = 9-2y
The width of the rectangle = 7
Now
The perimeter (P) of the rectangle is :
[tex]P = 2( \text{Length} + \text{width})[/tex]
[tex]P= 2(9-2y+7)\\P=18-4y+14\\P=32-4y[/tex]
Hence, the perimeter of the rectangle is 32-4y.

Step-by-step explanation:
The parallelograms ABCD and [tex]A_{1} B_{1} C_{1}D_{1}[/tex] are similar.
Now, AB = 8 (Given in the figure), so CD = 8.
Now, we can write, [tex]\frac{BC}{B_{1}C_{1}} = \frac{CD}{C_{1}D_{1}}[/tex]
⇒ [tex]\frac{BC}{3} = \frac{8}{5}[/tex]
{Since, given that [tex]B_{1}C_{1} = 3[/tex] and [tex]C_{1}D_{1} = 5[/tex]}

You go to a school dance. There is an entrance fee, and there are slices of pizza for sale. After having 1 slice of pizza, you have spent a total of $6. After having 2 more slices of pizza, you have spent a total of $10. Write an equation that represents the total cost y after buying x slices of pizza at the dance
Answer:
Equation that represents the total cost is y = 4 + 2 x
Step-by-step explanation:
Here, x : slices of pizza eaten at the dance.
y : total cost paid in the school dance
Let a : Cost of each slice of pizza.
So, according to the question:
Entrance fee + cost 1 slice of pizza = $6
or, Entrance fee = $ 6 - Cost of 1 slice ....... (1)
Similarly, Entrance fee + cost 3 slice of pizza = $10
or, Entrance fee = $ 10 - Cost of 3 slice ............ (2)
Comparing both equation , we get:
$ 6 - Cost of 1 slice = $ 10 - Cost of 3 slice
or, 6 - a = 10 - 3 a
or, 2 a = 4
⇒ a= 2, So the cost of each slice of pizza = $2
Putting the value of a in 1 we get
Entrance fee = 6 - $ 2 =$4
Now, the cost of x slice of pizza = x ( $2) = 2x
So, the total cost y for x slice of pizza = Entrance fee+ Cost of x slices
or, y = $ 4 + 2 x
Equation that represents the total cost is y = 4 + 2 x
Final answer:
The equation that represents the total cost y after buying x slices of pizza is y = 2x + 4, which includes the cost of each slice of pizza ($2) and the entrance fee ($4).
Explanation:
To write an equation that represents the total cost y after buying x slices of pizza at the dance, you can use the information given to create two points: (1, $6) and (3, $10). From the first point, you know there is a fixed entrance fee plus the cost of one slice of pizza. By the time you purchase two more slices (for a total of three), the cost is $10. This scenario implies that each additional slice of pizza has a constant price.
With two points, you can find the slope of the line, which represents the price of each slice of pizza. The slope m is the change in cost divided by the change in the number of slices: m = ($10 - $6) / (3 - 1) = $4 / 2 = $2 per slice. The entrance fee is the y-intercept of the line, which is the initial cost without any pizza, and can be found by extending the line back to the y-axis. The total cost without any pizza is the cost after one slice minus the cost of that slice, which gives us $6 - $2 = $4.
The final equation becomes y = 2x + 4, where y represents the total cost and x represents the number of slices of pizza purchased.
Mr. Johnson's lunch bill is $29.90, which includes a 15% típ
What is the price before tip, b, of Mr. Johnson's lunch?
Answer:
price before tip (b) = $26
Step-by-step explanation:
29.90 is INCLUDING tip, so the real bill, b, would be less.
Now, since 29.90 is including 15% tip, and we let the original bill be "b", we can say:
b INCREASED by 15% gives us 29.90
We need to come up with an equation and solve for b.
15% means 15/100 = 0.15
Now, we can write:
b + 15% of b = 29.90
or
b + 0.15b = 29.90
then
1.15b = 29.90
b = 29.90/1.15
b = 26
So, price before tip (b) = $26

Step-by-step explanation:
The straight line BD passes through points B(2a,2b) and D(c,0).
Therefore, the equation of the straight line BD will be given by
[tex]\frac{y - 2b}{2b - 0} = \frac{x - 2a}{2a - c}[/tex]
⇒ [tex]y - 2b = \frac{2b}{2a - c}x - \frac{4ab}{2a - c}[/tex]
⇒ [tex]y = \frac{2b}{2a - c} x - \frac{4ab}{2a - c} + 2b[/tex]
⇒ [tex]y = \frac{2b}{2a - c} x + \frac{-4ab + 4ab - 2bc}{2a - c}[/tex]
⇒ [tex]y = \frac{2b}{2a - c} x - \frac{2bc}{2a - c}[/tex]
Therefore, third option is correct. (Answer)
We know that the equation of a straight line passing through the points ([tex]x_{1},y_{1}[/tex]) and ([tex]x_{2},y_{2}[/tex]) is given by
[tex]\frac{y - y_{1} }{y_{1} - y_{2}} = \frac{x - x_{1} }{x_{1} - x_{2}}[/tex]

The word sentence translates to the inequality 'g / -2 < -6', representing the relationship where the quotient of a number g and -2 is less than -6.
Writing the word sentence 'The quotient of a number g and -2 is fewer than -6' as an inequality involves translating the words into a mathematical expression. Inequality symbols are used to show how two measurements, or in this case, expressions, are related. The quotient of a number and another number is represented by the division of those two numbers. 'Fewer than' indicates that the expression on the left side is less than (<) the expression or value on the right side.
Therefore, the statement can be translated to the mathematical inequality as g / -2 < -6. This inequality shows the relationship between the variable g and the numbers -2 and -6, with the quotient of g and -2 being less than -6.

If A and B are independent events, P(A and B) =
P(a)
Explanation I just did it :)
For independent events A and B, the probability of both occurring P(A and B) is the product of their individual probabilities: C. P(A) * P(B).
What are independent events?Independent events are events in probability theory where the occurrence of one event does not affect the occurrence or likelihood of the other.
Let's use the definition of independent events to derive the formula for the probability of the intersection of two independent events.
If events A and B are independent, then the definition of independence is given by:
P(A and B) = P(A) * P(B)
This means that the probability of both events A and B occurring is the product of the individual probabilities of A and B.
So, if A and B are independent events, P(A and B) = P(A) * P(B). Therefore, the correct answer is C. P(A) * P(B).
