Answer:
90 cents
Step-by-step explanation:
Find how much money you have by plugging in 18 as n into the expression:
5n
5(18)
Multiply:
= 90
So, when you have 18 nickels, you have 90 cents
For each of these sequences below: (a) describe the term-to-term rule (b) calculate the tenth term 4.1) 3 6 9 12 15 4.2) 5 11 17 23 29
Answer: The term to term rule is an Arithmetic progression for the two question. B) 1Oth term for the first is 30 and for the second series is 59
Step-by-step explanation:
4.1) 3 6 9 12 15
For the sequence above, we can see that the next term is gotten by addition of 3 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =3
And d common difference =3(6-3,9-6,12-9)
10th term=
T10 = 3+ (10 - 1)3.
T10 = 3+ (9)3.
T10 = 3+ 27.
T10 =30
4.2) 5 11 17 23 29
For the sequence above, we can see that the next term is gotten by addition of 6 with the previous term and so It is an Arithmetic progression.
Having in mind the nth term of an AP as Tn = a + (n - 1)d.
where a is the first term =5
And d common difference =6 (11-5, 17-11,23-17)
10th term=
T10 = 5+ (10 - 1)6.
T10 = 5+ (9)6.
T10 = 5+ 54.
T10 =59
The area of cross section of the large piston in a hydraulic machine is 1m² and that of small piston is 0.5m².calculate the force that must be applied on the small piston to lift a load of 1000N on the large piston
Answer:
The force that must be applied on the small piston has a magnitude of 500 newtons.
Step-by-step explanation:
By Pascal's Principle, we know that pressure within any point of a closed hydraulic system is the same. Hence, the hydraulic machine can be described by the following model:
[tex]\frac{F_{1}}{A_{1}} = \frac{F_{2}}{A_{2}}[/tex] (1)
Where:
[tex]F_{1}, F_{2}[/tex] - Forces applied on the small and large pistons, in newtons.
[tex]A_{1}, A_{2}[/tex] - Areas of the small and large pistons, in square meters.
If we know that [tex]A_{1} = 0.5\,m^{2}[/tex], [tex]A_{2} = 1\,m^{2}[/tex] and [tex]F_{2} = 1000\,N[/tex], then the force to be applied on the small piston is:
[tex]F_{1} = \left(\frac{A_{1}}{A_{2}} \right)\cdot F_{2}[/tex]
[tex]F_{1} = \left(\frac{0.5\,m^{2}}{1\,m^{2}} \right)\cdot (1000\,N)[/tex]
[tex]F_{1} = 500\,N[/tex]
The force that must be applied on the small piston has a magnitude of 500 newtons.

Find the range of the graphed function.
Range is set of all y-values. To find a range of graphed function, we need to know that range starts from the minimum value of graph to maximum value. That's because the minimum value is the least value that you can get by substituting the domain and the maximum value is the largest value that you can get by substituting the domain as well.
Now we don't talk about domain here, we talk about range. See the attachment! You are supposed to focus on y-axis, plane or vertical line. See how the minimum value of function is the negative value while the maximum value is positive.
That means any ranges that don't contain the negative values are cleared out. (Hence A and C choices are wrong.)
Next, range being set of all real numbers mean that graphed functions don't have maximum value or minimum value (We can say that both max and min are infinite.)
Take a look at line graph as an example of range being set of all real numbers, or cubic function.
Answer/Conclusion
The range exists from negative value which is -9 to the maximum value which is 5.That means the range is -9<=y<=5What is the sign of -x/-y when x > 0 and y > 0?
Answer:

hope this helps, have a great day!
Answer:
A is correct
Step-by-step explanation:
if we know that both x and y are positive, they are both going to be negative
and since we know that, -x divided by -y is the same as saying something negative divided by something negative which is ALWAYS positive because negatives cancel out leaving the answer positive something, something

What is the answer to the expression -5x + 1 = 31
Answer:
x = -6
Step-by-step explanation:
-5x + 1 = 31
Subtract 1 from each side
-5x + 1-1 = 31-1
-5x = 30
Divide by -5
-5x/-5 = 20/-5
x = -6
Answer:
x = - 6
Step-by-step explanation:
- 5 x + 1 = 31
subtract 1 from 31
- 5 x = 31 - 1
- 5 x = 30
Divide 30 by - 5
x = 30 / - 5
x = - 6

Solution :-
As per the provided information in the given question, we have been given that the radius of the sphere is 5 inches. We have been asked to find or calculate the surface area of the sphere.
To calculate the surface area of the sphere, we will use the formula below :-
[tex]\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_{(Sphere)} = 4\pi r^2 \:\:}}[/tex]
Substitute the given values into the above formula and solve for surface area:
[tex]\sf:\implies Surface \: Area_{(Sphere)} = 4\pi r^2[/tex]
[tex]\sf:\implies Surface \: Area_{(Sphere)} = (4)(3.14)(5 \: in)^2[/tex]
[tex]\sf:\implies Surface \: Area_{(Sphere)} = (4)(3.14)(25 \: in^2)[/tex]
[tex]\sf:\implies Surface \: Area_{(Sphere)} = (4)(78.5 \: in^2)[/tex]
[tex]\sf:\implies \bold{Surface \: Area_{(Sphere)} = 314 \: inches^2}[/tex]

A regular octagon has a perimeter of 30 centimeters. Find the length of each side.
Step-by-step explanation:
Perimeter=8l
30cm=8l
l=30/8=3.75cm
Answer and Step-by-step explanation:
An octagon has 8 sides in total. The perimeter of a shape is the sum of all sides added together.
To find the length of each side, we divide the perimeter by the amount of sides.
30 ÷ 8 = 3.75
The answer is 3.75 centimeters.

Answer:
Step-by-step explanation:
U still in school
Answer:
42 square units
Step-by-step explanation:
We can divide the figure in two triangles and one rectangle
the two triangles are congruent
base = |-5-2| = 7
height = 2
Total area of the two triangles = (7 *2)/2 * 2 = 14 square units
the rectangle have the length that is equal to the base of the triangles
height = |-2-2| = 4
Area = 7 *4 = 28 square units
Final area = 14+ 28 = 42 square units

AB - CD Point Pis the midpoint of AB. Point Q is the midpoint of CD. Point Ris the midpoint of AP. Point Sis the midpoint of QD
is an invalid relation.
Because point Ris the midpoint of AP and point Sis the midpoint of QD
we can conclude that
Answer:
The invalid statement is 4) Segment AP is congruent to segment PQ.
We conclude that 2) Segment RB is congruent to segment CS.
Step-by-step explanation:
Hope this Helps Have an good day!!
Given, line segment AB & CD
Here, P is the midpoint of AB ⇒ AP=PB
& Q is the midpoint of CD ⇒ CQ=QD
It is given that P is point on AB not on CD ∴ there is no relation of point P with line segment CQ.
Hence, the invalid statement is
Segment AP is congruent to segment PQ.
Now, given that R is the midpoint of AP ⇒ AR=RP
& S is the midpoint of QD ⇒ QS=SD
AB≅CD (Given)
≅
PB ≅ CQ (∵from midpoint statements)
∵ PA=QD ⇒ PR=QS
Because PB≅CQ
PB+PR≅CQ+QS
⇒ RB≅CS
Therefore, Segment RB is congruent to segment CS
Answer:
Segment AP is congruent to segment PQ
Segment RB is congruent to segment CS
