I will give brainliest Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.

Answer:
The value is 0.025
Step-by-step explanation:
We get the z-score that is equal to the given value
Mathematically we have this as:
z-score = (x-mean)/SD
x = 93
mean =79
SD = 7
So we have the z-score as;
z-score = (93-79)/7 = 14/7 = 2
So we want to calculate the probability equal to the calculated z-score value of 2
Using the standard normal distribution table, we have this value as;
1 - 0.975= 0.025

Problem 1:
The height of water in a bathtub, w, is a function of time, t. Let P represent this function. Height
is measured in inches and time in minutes.
Match each statement in function notation with a description.
A: P (0)=0
1: After 20 minutes, the bathtub is empty.
B:P (4)= 10
2: The bathtub starts out with no water.
C:P (10) = 4
3: After 10 minutes, the height of the water is 4 inches.
D: P (20) = 0
4: The height of the water is 10 inches after 4 minutes.
Answer:
A = 2
D = 1
B = 4
C = 3
Step-by-step explanation:
Height of water in bathtub is a function of water in bathtub.
P(t) = w ; t = time ; w = height of water.
A: P (0)=0 ; At time, t = 0 ; height of water = 0, there is no water on bathtub
2: The bathtub starts out with no water.
D: P (20) = 0 ; At time, t = 20 ; w = 0 ;the tub is empty.
1: After 20 minutes, the bathtub is empty.
B:P (4)= 10 `; At t = 4, w = 10 ; height of water in bath tub is 10
4: The height of the water is 10 inches after 4 minutes
C:P (10) = 4 ; At t = 10, w =4, height of water in bathtub = 4 inches
3: After 10 minutes, the height of the water is 4 inches.

find the values of the variables
Answer:
x = 31 and y= 11
Step-by-step explanation:
Since sum f angles on a straight line is 180°, hence;
2x+8+3x+17 = 180
Collect like terms
5x+25 = 180
5x = 180-25
5x = 155
x = 155/5
x = 31°
Similarly;
3x+17+5y+15 = 180
Substitute x = 31 into the equation
3(31)+17+15+5y = 180
93+32+5y = 180
125+5y =180
5y = 180-125
5y = 55
y = 55/5
y = 11°
Hence x = 31 and y= 11

Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.
Complete Question:
Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.
Write an equation using the Pythagorean Theorem to find the value of x.
How far are Ava's feet from the balloon?
Answer:
Ava's feet is 17ft away from the balloon
Step-by-step explanation:
Given
[tex]height = 8ft[/tex]
[tex]distance = 15ft[/tex]
The attached image represents the scenario
Using Pythagoras theorem (from the attachment), we have:
[tex]x^2 = 8^2 + 15^2[/tex]
[tex]x^2 = 64 + 225[/tex]
[tex]x^2 =289[/tex]
Take square roots of both sides
[tex]x = \sqrt{289[/tex]
[tex]x = 17[/tex]

the model represents the equation x - 1 < -4. What is the solution for the inequality?
Answer:
any number equal to or less than -4
Step-by-step explanation:
x - 1 < -4
< represents that -4 is a larger number than x - 1. we know that -4 is a negative number, so anything below -4 would be less. x = -4 would be a good solution, but the reality is that any number equal to or less than -4 is the correct answer. I hope this helps!

In a school the ratio of boys to girls is 2.3. If there are 300 girls in the school, then
how many boys are there?
(A) 50
(B) 120
(C) 100
(D) 150
(E) 200
Answer:
e is the answer i think.
Step-by-step explanation:
Answer:
E. 200 boys
Step-by-step explanation:
there are 2 boys for every 3 girls
so if we multiply the amount of girls by 100 to get 300 girls
then we need to multiply the amount of boys by 100 too because what you do to one side you have to do to the other
2*100= 200
200 boys for 300 girls can be simplified to the ratio 2:3 by dividing by 100 so we know our answer is correct

A balloon lifts off the ground and reaches a height of 200m. The total mass of the balloon is 1000 kg. What is the GPE of the balloon?
Answer:
1,960,000Joules
Step-by-step explanation:
Gravitational Potential Energy is expressed as;
GPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Given
m = 1000kg
h = 200m
g = 9.8m/s
Substitute;
GPE = 1000 * 9.8 * 200
GPE = 9800 * 200
GPE = 1,960,000Joules
Hence the GPE of the balloon is 1,960,000Joules

2x + 2y=14
5x - 3y = 19
The value of x is 5 and y is 2 .
What is elimination method?The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the question
2x + 2y=14 ------------------- (1)
5x - 3y = 19 ------------------- (2)
Now,
solving both equation by elimination method
Multiplying equation (1) by 3 and by 2 to equation (2)
to make equal coefficient for y
So, y can be eliminated
3(2x + 2y)=14 * 3
6x + 6y = 42 -------------- (3)
2(5x - 3y) = 19*2
10x - 6y = 38 -----------------(4)
Now,
Adding both eq(3) and (4)
16x = 80
x = 5
Putting value of x in eq(1)
2*5 + 2y=14
10 + 2y = 14
2y = 4
y = 2
Hence, The value of x is 5 and y is 2 .
