Dawn is ordering 1 veggie sandwich for every 3 ham sandwiches. She needs 12 sandwiches in all. Veggie sandwiches cost 4.00 dollars each and ham sandwiches cost 4.50 each. How many will dawn spend on sandwiches?
Answers
Answer:
$52.50
Step-by-step explanation:
Lets use V for Veggie, and H for Ham.
V=4
H=4.50
She is getting 12 sandwiches, and Every 3 H, she buys one V.
So, the order of her buying the sandwiches would be:
H H H V H H H V H H H V
9 H and 3 V
9*H=40.5
3*V=12
40.5+12= $52.50
The total cost of all the sandwiches is given by the equation A = $ 52.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total cost of 12 sandwiches be A
Now , the equation will be
For every 1 veggie sandwich 3 ham sandwiches are ordered by Dawn
The cost of veggie sandwich = $ 4.00
The cost of ham sandwich = $ 4.50
So ,
Let the veggie sandwich be = x
Let the ham sandwich be = y
The total number of sandwiches = 12
So , x + 3y = 12
when x = 3 and y = 3
3 + 3 ( 3 ) = 12
3 + 9 = 12
12 = 12
Therefore , the number of veggie sandwich = 3
The number of ham sandwich = 9
And , the cost of 3 veggie sandwich = 3 x 4.00
The cost of 3 veggie sandwich = $ 12
The cost of 9 ham sandwich is = 9 x $ 4.50
The cost of 9 ham sandwich is = $ 40.5
The total cost of 12 sandwich A = cost of 3 veggie sandwich + cost of 9 ham sandwich
Substituting the values in the equation , we get
The total cost of 12 sandwich A = 12 + 40.50
The total cost of 12 sandwich A = $ 52.50
Therefore , the value of A is $ 52.50

At a strawberry stand Luisa paid $4.50 for 2 pounds of strawberries. How much would you expect to pay for five pounds or strawberry?
Answers
Half of 4.50 is 2.25, so for one pound it would be $2.25.
To calculate five pounds, you need to add 2.25+2.25+2.25+2.25+2.25 = 11.25.
For five pounds of strawberry's, it would cost $11.25.

Answers
Given:
The company charges $250 for the onetime set-up fee and $23 for each printed jersey.
To find:
The expression that represents the total cost of x number for the team.
Solution:
We have,
Fixed charges = $250
Additional charges = $23 per printed jersey
Let x be the number of printed jersey. Then,
Additional charges = $23x
Total chargers = Fixed charges + Additional charges
= $(250 + 23x)
Therefore, the expression for the total charges is $(250 + 23x).

Line q goes through points (-3, 3) and (-5, -3). At what point does line q cross the y-axis?
Answers
Answer:
(0, 12 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (- 5, - 3)
m = [tex]\frac{-3-3}{-5+3}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = - 9 + c ⇒ c = 3 + 9 = 12 ← y- intercept
Thus the line crosses the y- axis at (0, 12 )
Answer:
It crosses the y-axis at the point where y = 12
- the point (0, 12).
Step-by-step explanation:
First we need to find the equation of the line q:
The slope of the line = (-3-3)/(-5-(-3))
= -6/-2
= 3.
Using the point-slope form of a line:
y - y1 = m(x - x1) Take the point (-3, 3):
y - 3 = 3(x -(-3)
y - 3 = 3x + 9
y = 3x + 12.
Where q crosses the y-axis x = 0 so we have
y = 3(0) + 12
y = 12
The required point is (0, 12).

What is the exact volume of the cone? with a 5 ft radius and a 16 ft height
Answers
Answer:
The volume is 418.93 ft^3
Step-by-step explanation:
Here, we want to find the volume of a cone
Mathematically, we use the formula;
V = 1/3 * pi * r^2 * h
r = 5 ft
h = 16 ft
Substituting these values;
V = 1/3 * 3.142 * 5^2 * 16
V = 418.93 ft^3

a collector purchased a rare book for $97.56 and then sold the book in an online auction for $141.82. The auction charged the collector $8.25 in fees for the use of its service. how much did the collector earn by selling the book
Answers
Answer:
$36.01
Step-by-step explanation:
141.82 - 8.25 = 133.57
133.57-97.56=36.01
The collector earned a total of $36.01 by selling the book.
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
The collector earned $141.82 - $97.56 = $44.26 by selling the book.
To find the total amount the collector earned, we need to subtract the price they paid for the book from the price they sold it for. This gives us the profit that the collector made on the sale of the book.
However, we also need to subtract the auction fees that the collector had to pay.
The collector paid $8.25 in fees, so their total earnings from the sale of the book were :
⇒ $44.26 - $8.25
Apply the subtraction operation, and we get
⇒ $36.01.
Therefore, the collector made a total of $36.01.
