The sum of two numbers is 68. Their difference is 15. Write a system of equations you could use to solve this problem.
Answer:
x+y=68
x-y=15
Step-by-step explanation:
A "sum" means that we will be using addition, while a "difference" indicates subtraction. Anytime we have two unknown numbers we generally use "x" and "y".
Jonathan is making his
favorite pasta dish. He
serves his mom 1/12 of the
pot of pasta and his brother
1/6 of the pot. How much of
the pot is left over?
Answer: 3/4
Step-by-step explanation:
1/6 = 2/12
2/12 + 1/12 (the brother and the mom’s pieces) = 3/12->1/4
1 - 1/4 =3/4

1/72 x 648
Answer:
The answer is 9
Step-by-step explanation:
Multiplying by 1/72 is the same as dividing by 72. When you multiply 648 by 1/72, think of it as multiplying
[tex]\frac{648}{1}[/tex] x [tex]\frac{1}{72}[/tex] which equals...[tex]\frac{648}{72}[/tex]. If you have a calculator, at that point, you can just divide 648 by 72. If not, you can use standard division.
Hope this helps!

Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit in the triangle is centered at (0,0) and passes through the point (1.2,1.6) Approximately what percentage of the triangle does the circle cover?
Answer:
52.36%
Step-by-step explanation:
First, you need to find the radius of the circle. You can do this by using the Pythagorean theorem, which states a^2+b^2=c^2. In this case, a and b are equal to 1.2 and 1.6, and c is the radius of the circle. Plugging in we get 1.2^2+1.6^2=c^2 or 1.44+2.56=c^2 or 4=c^2. Finding the square root of both sides of the equation, we find that 2=c. Now that we have the radius, we can find the area of the circle. The area of a circle is expressed as πr^2, and plugging in 2 for r we get an area of 4π, or ~12.56637. Now all we do is divide 12,56637 by 24 and get what percentage of the area of the triangle the circle covers, which is roughly 0.5236, or 52.36%
What is the volume of the following shape?
Answer:
[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]
Step-by-step explanation:
We can divide it into two parts:
First, we can fin the volume of the parallelepiped:
h1 = 16 cm
w1 = 2 cm
d1 = 3 cm
[tex]V_{1}=h_{1}*w_{1}*d_{1}=16*2*3=96\: cm^{3}[/tex]
Now, the volume of the second parallelepiped is:
h2 = (8-2) cm = 6 cm
w2 = 2 cm
d2 = 3 cm
[tex]V_{2}=h_{2}*w_{2}*d_{2}=6*2*3=36\: cm^{3}[/tex]
Finally, the total volume will be the addition of these two volumes.
[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]
I hope it helps you!

What is the area of the polygon in square units?
Answer:
(d) 80 square units
Step-by-step explanation:
As with many composite area problems, this can be worked any of several ways. The attached shows trapezoid ABCE, from which triangle CDE can be removed to get the desired area.
The relevant formulas are ...
A = (1/2)(b1 +b2)h . . . . . . area of a trapezoid
A= (1/2)bh . . . . . . . . . . . . area of a triangle
__
Here, the trapezoid has bases 12 and 2, and height 12, so its area is ...
A = (1/2)(12 +2)(12) = 84 . . . . square units
The triangle has a base of 4 and a height of 2, so its area is ...
A = (1/2)(4)(2) = 4 . . . . square units
Then the area of the desired figure is ...
84 - 4 = 80 . . . . square units

Which equation would represent exponential decay?
a. f (x) = 4(1.03)^x
b. f (x) = -2x - 5
c. f (x) = -3(1.02)^x
d. f (x) = 2(.87)^x
Answer:
D
Step-by-step explanation:
The .87 represents that the new value is 87% of the previous value, thus decaying exponentially. B decays linearly and the other two are exponential growth functions.
The supplement of an acute angle is an obtuse angle. True or false?
Vertical angles are always supplementary. True or False?
Answer:
yes, it is true because a supplimentary angle is 180 degrees and if their is an acute angle then it is less than 90 degrees which means you subtract that by 180 and you get a number over 90 and an obtuse angle is over 90 which means the other side of the acute angle is obtuse. And the suppliment to an acute angle is always over 90 degrees
Hope it helps!

The sugar sweet company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $6594 to rent trucks plus an additional fee of $225.75 for each ton of sugar.
Question 1: for what amount of sugar to the two companies charge the same?
Question 2: what is the cost when the two companies charge the same?
If the ratio of two numbers is9:2and their difference is 63 .Find the two numbers
Answer:
The two numbers are 18, and 81.
step-by-step explanation:
If you divide both sides of the ratio by 2 to get 4.5/1, you can then graph that as y=4.5x, finally you just find two numbers that have a difference of 63, which in this case is 18, and 81.

Pls help I don’t understand
Answer:
1. 7 1/4
2. 3 1/4
3. 2 2/3
4. 2 1/2
Step-by-step explanation:
1. You subtract 8-3/4=7 1/4
2. You have to add 2 3/4 hour + 1/2 an hour = 3 1/4 hours
3. You take 3 2/6 - 2/3= to make it easier you want to change the fractions so there the same denominator 2/6->1/3 now it will be much easier to subtract 3 1/3-2/3= 2 2/3
4. Finally you do 8-5 1/2 =2 1/2
I hope this helps if not you can comment and I'll try and further explain

Marks books has an area of 48 in.². The perimeter of the book is 52 inches. what are the dimensions of the book
Answer:
dimensions of the book are 2 in. by 24 in.
Step-by-step explanation:
I assume the book is a rectangle
Let w = the width
l = the length
A = lw = 48 P = 2w + 2l = 52
w + l = 26
l = 26 - w
w(26-w) =48
26w - [tex]w^{2}[/tex] = 48
[tex]w^{2} - 26 w + 48 = 0[/tex]
(w-2)(w -24) = 0
w = 2 or w = 24
if w = 2, then l = 26 - 2 = 24
if w = 24, then l = 26 - 24 = 2
So, the dimensions of the book are 2 in. by 24 in.
