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

John is painting a box that is shaped like a cube. 1/10 of a bottle of paint covers 2/5 of the box. How many cubes can he paint with 2 bottles of paint?
Answer:
8
Step-by-step explanation:
1/10 bottle of paint covers 2/5 of box
2 bottles of paint will cover x of box
Using cross multiplication :
1/10 = 2 / 5
2 = x
(1 / 10)x = 2/5 * 2
x / 10 = 4 / 5
Cross multiply :
5x = 40
Divide both sides by 5
x = 40/5
x = 8
Hence, 2 bottles of paint will be used to paint 8 boxes
9 ounces = how many pounds? in fraction form
Answer:
9/16 pounds
Step-by-step explanation:
1 pound = 16 ounces
With this information, we have make a proportion to find the number of pounds 9 ounces is
Let p = the number of pounds
16/1 = 9/p
Multiply both sides by 1 to get
16 = 9/p
Multiply both sides by p
16p = 9
Divide both sides by 16
p = 9/16
This fraction is in its simplest form and can't be simplified any more.

Un elev a depus la banca suma de 250 lei. Știind ca banca oferă dobânda anuala de 1%,iar stația impozitează dobânda cu 16%,aflati ce suma va avea elevul după un an de depunere.
Răspuns:
292,50
Explicație pas cu pas:
Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17
Suma principală depusă, P = 250
Suma totală, A după 1 an poate fi calculată astfel:
A = P (1 + rt)
Unde ; r = rata dobânzii; t = timp
A = 250 (1 + (0,17 * 1))
A = 250 (1,17)
A = 292,5

red bike is traveling south, toward Lawrence, at constant speed of 24km/h and a blue bike is also traveling east, away from Lawrence, at a constant speed of 12 km/h. when t=0, the red bike is 10 km north and the blue bike is 6 km east of Lawrence a. express the distance of the red bike from Lawrence, R, as a function of time in hours, t. b. express the distance of the blue bike from Lawrence, B, as a function of time in hours, t.
Answer:
a.[tex]R=10-24t[/tex]
b.[tex]B=6+6t[/tex]
Step-by-step explanation:
We are given that
Speed of red bike, v=24 km/h
Speed of blue bike, v'=12km/h
Distance of red bike when t=0
=10 km north
Distance of blue bike when t=0
=6km east
a. We have to find the expression of distance of red bike from Lawrence.
[tex]Distance=speed\times time[/tex]
Let t be the time taken by red bike
Distance of red bike from Lawrence is given by
[tex]R=10-24\times t[/tex]
[tex]R=10-24t[/tex]
b.
Distance of the blue bike from Lawrence
[tex]B=6+6\times t[/tex]
