Answer:
Let affan have x no. of stamps Then,
According to the question Ayaan has 20 stamps more than 3 times the number of stamps Affan has. Then,
x = 3x + 20
Now they both have 140 stamps all together. so,
x + 3x + 20 = 140
or, 4x = 140 - 20
or x = 120/4
or, x = 30
Therefore, Affan has 30 stamps .
Hope this helps
Hope this helpsALL THE BEST !!
The number of stamps Affan has is 30.
What is Algebraic expression ?
Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.
Let us suppose that :
x = the number of Ayaan stamps
y = the number of Affan stamps
Ayaan has 20 stamps more than 3 times the number of stamps Affan has means :
x = 3y + 20.....(1)
both of them together have 140 stamps means :
x + y = 140...........(2)
Solve by substitution :
substitute equation 1 in equation 2 and solve for y
x + y = 140
3y + 20 + y = 140
4y = 120
y = 30
now, the value of x will be :
x + y = 140
x = 120 - 30
x = 90
therefore, The number of stamps Affan has is 30.

3. A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. 12 radius 18 height
Answer:
8138.88 cubic unit.
Step-by-step explanation:
Given that,
Radius, r = 12
Height, h = 18
We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :
[tex]V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88\[/tex]
So, the volume of the cylinder is 8138.88 cubic unit.

Solve for x. 200/25 = x/2 (If you do help thank you)
Answer: 16
Step-by-step explanation: I don't know how to explain.
Answer:
16
Step-by-step explanation:
Divide both 200/25 = x/2
Multiply all the terms by the same value to eliminate fraction denominators
8 = x/2
2*8=2* x/2
Cancel multiplied terms that are in the denominator
2*8=2*x/2
2*8=16
x=16

Answer:
You can graph it . I got and answer of 2 , 4 , 5,
Write the slope of the line containing each pair of points.
1. (3, 4) and (5, 7)
2. (5, 2) and (9,4)
Kinda confused on this
Answer:
1) 1.5 2) 0.5
Step-by-step explanation:
To find slope using two points like (x1,y1) and (x2,y2), the slope is (y2-y1)/(x2-x1), so for first question (7-4)/(5-3) = 3/2 = 1.5, and same for the second question.

Step-by-step explanation: this is for i-ready46005.75 rouneded to the nearest tenth of a cubic inch
Answer:
46005.8
Step-by-step explanation:
Because you look to the left of 7 and 5 is higher than 4 so you round up.
So the 7 changes into a 8 and the rest stays the same.
The first term of a geometric sequence is 18 and the multiplier is 3.5. What is the 5th term of the sequence?
Answer:
2701.125
Step-by-step explanation:
fifth term = 18(3.5)^4
Answer:
a₅ = 2701.125
Step-by-step explanation:
Multiply each term by 3.5 , that is
a₁ = 18
a₂ = 3.5 × 18 = 63
a₃ = 3.5 × 63 = 220.5
a₄ = 3.5 × 220.5 = 771.75
a₅ = 3.5 × 771.75 = 2701.125

Find the equation of the straight line which passes through each of the following pairs of points.
(1,4) (3,10)
Answer:
y = 3x + 1
Step-by-step explanation:
First, find slope:
[tex]y2 - y1 / x2 - x1[/tex]
[tex]10 - 4/ 3 - 1 = 6 / 2 = 3[/tex]
Then, put the equation into point-slope form using the point (1, 4):
[tex]y - y1 = m(x - x1)[/tex]
where m is the slope
y - 4 = 3(x - 1)
If you want to put this into slope-intercept form, it would be
[tex]y-4=3(x-1)\\y - 4 = 3x - 3\\y = 3x + 1[/tex]

Contrasting Kinetic and Thermal Energy
Answer:
Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
Step-by-step explanation:
Differences:
So, the main difference between thermal and kinetic energy is that the first one is random motions of particles that you mostly can't see by eye, while the second is a unified motion of these same particles, which you can then see. As you say, kinetic energy of large objects can be converted into this thermal energy.
The difference between Kinetic and Thermal Energy is simple. Thermal Energy comes from heat which is generated by molecules moving around very fast (kinetic energy does tie in here but Thermal and Kinetic Energy are still not the same). Kinetic Energy is generated by speed and mass, and whenever an object is moving fast it has Kinetic Energy, if something is sitting still it has Potential Kinetic Energy.
Hope this helps and have a nice day.
