Charles buys 10 drinks and 3 sandwiches for $34. Isabel buys 5 drinks and 4
sandwiches for $37. They want to determine the cost of each item.
Write a system of linear equations to model the problem. Let d equal the cost
of each drink and let s equal the cost of each sandwich. Solve the system
algebraically. How much does each item cost?
Storage units are numbered 1 through 50. What is the probability that the operator will choose a unit that is not a multiple of 8?
Answer:
22/25
Step-by-step explanation:
Multiples of 8 betwen 1 - 50 =
8
16
24
32
40
48
there are 6 multiples of 8
Numbers that are not multiples of 8 = 50 - 6 = 44
Probability the operator will choose a unit that is not a multiple of 8 = 44/50
Expressing in simpler terms = 22/25

Your math test has 38 questions and is worth 200 points. The test consists
of multiple-choice questions worth 4 points each and open-ended questions
worth 20 points each. How many of each type of question are there?
... please solve this using if systems of equations
Answer:
Number of multiple-choice questions = x = 35 questions
Number of open-ended questions = y = 3 questions
Step-by-step explanation:
Let
Number of multiple-choice questions = x
Number of open-ended questions = y
x + y = 38 (1)
4x + 20y = 200 (2)
From (1)
x = 38 - y
Substitute x = 38 - y into (2)
4x + 20y = 200
4(38 - y) + 20y = 200
152 - 4y + 20y = 200
- 4y + 20y = 200 - 152
16y = 48
y = 48/16
y = 3
Substitute y = 3 into (1)
x + y = 38
x + 3 = 38
x = 38 - 3
x = 35
Number of multiple-choice questions = x = 35 questions
Number of open-ended questions = y = 3 questions

A cylinder has a radius of 6 meters. Its volume is 180 pi. cubic meters.
Find the height of the cylinder. *
Answer:
h = 5
Step-by-step explanation:
Formula for volume of a cylinder:
V = πr²h
r = 6
V = 180π
V = πr²h
180π = π6²h
180π = 36πh
(180π)/(36π) = h
h = (180)/(36)
h = 5

-1/3+y=1
Answer:
y=-3
Step-by-step explanation:
.....................
Answer to equation:
y = 1 1/3
Step-by-step explanation:
for this problem we see that we are starting below 0 and going up to one, all we have to do is solve for the distance between the two numbers, as shown
(-1/3) + 1/3 = 0
0 + 1 = 1
now to simplify, we just add the total amount of change between the two numbers
1/3 + 1 = 1 1/3
NOTE: this can be done by just adding the absolute value of each number if one is a negative number and one is a positive number, wich is basically what i did
-1/3 = |1/3|
1 = |1|
|1/3| + |1| = |1 1/3| or total amount of change
but if you are working with two positive or two negative numbers, then subtract the lesser of the two absolute values as so
-2 + x = -5
-2 = |2|
-5 = |5|
|5| - |2| = |3|
3 = amount of change
3 = x
-2 + -3 = -5

Answer:
see belowStep-by-step explanation:
4)for question 1 there is only a constant terms 2
hence, our answer choice is
a)25)Whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, ... (and so on)
hence our answer choices are
a)31b)06) degree of a expression means the exponent of the expression
since there's no number 3 as exponent
our answer choice is
False7) The Standard Form for writing down a polynomial is to put the terms with the highest degree first
hence our answer choice is
Dto simplify the expression
remember, law of exponent i.e [tex]\displaystyle x^m\times x^n=x^{m+n}[/tex]
[tex]\displaystyle (5x ^{2} y)(3x ^{3} y ^{4} )[/tex]
simplify:

Find the area of the hexagon. i will mark brainliest and pls explain.
Answer:
C. 150√3Step-by-step explanation:
Radius of the inscribed circle is the apothem of the hexagon.
Apothem (a) and half of the side (s) make a 30-60-90 right triangle.
The ratio of the legs, as per property of 30-60-90 triangle:
s : a = 1 : √3 ⇒ s : 5√3 = 1 : √3 ⇒ s = 5Half the side is s = 5 units, then side of the hexagon is 10 units.
The area of the hexagon:
A = 1/2Pa, P- perimeter, a- apothemA = 1/2(6*10)*(5√3) = 150√3Correct choice is C

explain how you can use absolute value to tell whether the fisherman or the end of his fishing line is farther from the surface of the water.
Answer:
So the answer is in your thoughts and also in your mind so therefor the answer is the fisherman is more farther away just by looking at him
Step-by-step explanation:
Answer:
The fisherman is farther away from the surface of water.
Step-by-step explanation:
So first of all, we know by looking at it that fisherman is farther away, but we need to use absolute value.
What is the absolute value of -12? 12.
That way, you can easily compare 16 and |-12|!

Find X .Round your answer to the nearest tenth of a degree.
Answer:
Step-by-step explanation:
With reference angle x
perpendicular (p) = 11
hypotenuse (h) = 18
Now
sin x = p / h
sin x = 11 / 18
x = sin ^-1( 11/ 18)
x = 37.66
x = 37.7
Awnser: 37.7
Sin: Oppostie/Hypotonuse
11/18=sin(x)
sin^-1(11/18)= 37.6698...
You earn $44.55 in 9 hours. Your friend earns $51.00 in 12 hours. How much do you AND your friend earn in 20 hours? HINT- You need to calculate how much you both make in 1 hour first! 1 point
Answer:
I earn $99. my friend earns $85. We both earn $184
Step-by-step explanation:
Steps
Find the amount earned per hour for each friend multiply the value gotten by 20 hours Add the amountAmount i earn per hour = 44.55 / 9 = $4.95
Amount my friend earns = 51 /12 = $4.25
Amount earned in 20 hours
4.95 x 20 = 99
4.25 x 20 = 85
