Answer:
number of students tickets = 80
number of adults tickets = 145
Step-by-step explanation:
Let
x = number of students tickets
y = number of adults tickets
x + y = 225 (1)
3x + 8y = 1400 (2)
From (1)
x = 225 - y
Substitute x = 225 - y into (2)
3x + 8y = 1400 (2)
3(225 - y) + 8y = 1400
675 - 3y + 8y = 1400
- 3y + 8y = 1400 - 675
5y = 725
y = 725/5
y = 145
Substitute y = 145 into (1)
x + y = 225 (1)
x + 145 = 225
x = 225 - 145
x = 80
number of students tickets = 80
number of adults tickets = 145
Compare and contrast the formulas for the volume of a pyramid and the volume of a cone.
Because a pyramid has a non-circular base, the volume is always described in square units, but the volume of a cone is stated in cubic units.
Because a pyramid has a non-circular base, the volume is always described in cubic units, but the volume of a cone is stated in square units.
Both formulas are 13Bh, but the base of a pyramid is always a square.
Both formulas are 13Bh, but the base of a cone is always a circle.

An engineer designs a cylindrical tank to have a capacity of 4356 cubic inches.
The tank has a diameter of d = 18.5 in. What is the height (h) of the tank to the
nearest tenth of an inch?
Answer:
16.2 in.
Step-by-step explanation:
Vol. of cylindrical tank = Bh, where B is the area of the base
Since the base is a circle, B = [tex]\pi r^{2}[/tex]
r = 18.5/2 = 9.25 and let's use 3.14 for π
So. 4356 =[tex]3.14(9.25^{2} ) h[/tex]
= 268.66625h
h = 4356/268.66625
h = 16.2134... = 16.2 in to the nearest tenth of an inch
Solve the equation using addition or subtraction
22 + 15 = d - 17
Answer:
d=54
Step-by-step explanation:
22 + 15 = d - 17
37=d-17
54=d
d=54
Answer:
d=44
Step-by-step explanation:
22+15=37 so ?-17=37 well its 44 because 44-17=37
what is the domain and range of the functions(3,1),(2.8), (1,9), (-3,7), (5,5)

Range = 1
(2,8) : Domain = 2
Range = 8
(1,9) : Domain = 1
Range = 9
(-3,7) : Domain = -3
Range = 7
(5,5) : Domain = 5
Range = 5
How do you find the radius of a circle
Answer
Just remember to divide the diameter by two to get the radius.
Step-by-step explanation:
If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation
25^x = 125^(x+3)
a. x = -10
b. x = -9
c. x = -3
d. x = 3
Answer:
25^x = 125^(x+3)
5^2x=5^3(x+3)
we get
2x=3(x+3)
2x=3x+9
-9=3x-2x
x=-9
option
b. x = -9 is right answer.
The solution is x = -9.
To solve the equation 25ˣ = 125ˣ⁺³, we can simplify the equation using the fact that 125 is equal to 5³.
Rewriting the equation with this substitution:
25ˣ = (5³)ˣ⁺³
Since [tex](a^b)^c[/tex] = [tex]a^{(bc)[/tex], we can simplify the equation further:
5²ˣ= (5³)ˣ⁺³
Now, we can see that both sides of the equation have the same base (5), so the exponents must be equal.
2x = 3(x+3)
Let's solve for x:
2x = 3x + 9
2x - 3x = 9
x = -9
Therefore, the solution is x = -9.

Which regular polygon would have each of its interior angles measure 120°?
nonagon
hexagon
octagon
heptagon
Answer:
Hexagon
Step-by-step explanation:
If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.

6,750,000 is what % of 9,000,000
Answer:
P = 9000000 × 6 100 = 9000000 × 0.06 = 540000 (answer) Therefore, the answer is 540000 is 6 percent of 9000000. Solution for '6 is what percent of 9000000?' The following question is of the type "P is what percent of W,” where W is the whole amount and P is the portion amount".
Answer:
75%
Step-by-step explanation:
I subtracted 6,750,000 from 9,000,000 and got 2,250,000.
I realized that that 2,250,000 is 25% of 9,000,000 so that leaves the remaining 6,750,000 to be 75%.
i am sorry if this doesn't make sense but that is how i figured it out.

or 48
or 9:48
you know
The value of x so that the ratios are equivalent is 48.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
Which shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
Therefore, the value of x so that the ratios are equivalent.
9:x and 54:8
x= 48
or 9:48
Hence, the value of x so that the ratios are equivalent is 48.
