Answer:
There are 6 mini cars and 12 tricycles.
Step-by-step explanation:
In the playground, there is a driving learning area that has mini cars and tricycles. If there are 18 vehicles and 64 tires in all, how many miniature cars and how many tricycles are there?
Given that there are a total of 18 vehicles in the driving learning area.
Let there are x number of the mini car,
so, the number of tricycles = 18-x
As one car has 4 tires, so the total number of car tires = 4x
As one tricycle has 3 tires, so the total number of tricycle tires = 3(18-x)
Given that the total number of tires is 60, so
4x+3(18-x) =60
4x+54-3x=60A
x=60-54=6
So, the total number of mini cars= 6
and the total number of tricycles = 18-6=12
Hence, there are 6 mini cars and 12 tricycles.

3) Graph by making a
table.
y=x
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]y = x[/tex]
Required
Plot the graph
First, we need to make a table.
To do this, we assume values for x
When [tex]x = 1[/tex]
[tex]y = x = 1[/tex]
[tex](x_1,y_1) = (1,1)[/tex]
When [tex]x = 2[/tex]
[tex]y = x = 2[/tex]
[tex](x_2,y_2) = (2,2)[/tex]
When [tex]x = 3[/tex]
[tex]y = x = 3[/tex]
[tex](x_3,y_3) = (3,3)[/tex]
When [tex]x = 4[/tex]
[tex]y = x = 4[/tex]
[tex](x_4,y_4) = (4,4)[/tex]
So, the table is:
[tex]x || 1 || 2 || 3 || 4[/tex]
[tex]y || 1 || 2 || 3 || 4[/tex]

Answer:
Domain (-2,3)
Range (-10, 20)
Function: Definitely
Step-by-step explanation: So check it right. Starting with Domain how far do our values go in the x direction positive and negative in this case the farthest to the left is -2 and to the right is 3. For range same thing but now we look at the y axis -10 is lowest and 20 is the highest. Open circles don't affect our domains or range but they are important for determining functions. This is a function because going up and down the graph vertically at any points doesn't collide with any point more than once. If the open circle were closed then this would not be a function but in this case it is a function.
Can someone help explain this to me!!! Been stuck on it for a while!!!
Answer:
Step-by-step explanation:
in the formula given. Asin(Bx) the A does mean Amplitude and the Bx is how fast the function repeats... and b/c sin is a function of pi (π) then if we want it to repeat every 2 of x then.. we do need to know the units of X .... but.. here it's just a number.. so we have to add the pi part.. b/c sin repeats every 2pi.... sooo....we are told that it's supposed to have an Amplitude of 3.... just how tall is the highest peak of the sin wave... so that's A = 3 .. and to repeat each time x gets to a multiple of 2.. like 2,4,6, ... ect.
so we have to add the pi part... so that each time x gets to 2 .. the function starts over. :/ this sounds confusing to me.. even as I explain it.. :/
A=3 B=π I'm sure that didn't help much :D ask a question i'll check back

enlist education system found in Nepal
Answer:
Education in Nepal was long based on home-schooling and gurukulas.[citation needed] The first formal school (Durbar School), established by Jung Bahadur Rana in 1853, was intended for the elite. The birth of Nepalese democracy in 1951 opened its classrooms to a more diverse population.[citation needed] Education in Nepal from the primary school to the university level has been modeled from the very inception on the Indian system, which is in turn the legacy of the old British Raj.[1]

what is the nth term of the arith metic sequence 10,16,22,28,......?
Answer:
nth term = 6n + 4 where n = no. of terms.
I hope it will be useful.
Answer:
[tex]a_{n}[/tex] = 6n + 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = a₂ - a₁ = 16 - 10 = 6, then
[tex]a_{n}[/tex] = 10 + 6(n - 1) = 10 + 6n - 6 = 6n + 4
The dimensions of a tin box are 4m * 3.5 m * 3m. If 25 such boxes are to be made. Find the area of the tin sheet required.

Answer:
The equation y = [tex]-\frac{8}{7}[/tex] x - 7 represents a line perpendicular to the given line
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1, which means if the slope of one line is m, then the slope of the perpendicular line to it is [tex]\frac{-1}{m}[/tex] (negative reciprocal)
The slope of the equation ax + by = c is [tex]\frac{-a}{b}[/tex], where a, b, c are constantThe slope of the equation y = m x + b is mLet us solve the question
∵ The equation of the given line is 7x - 8y = 16
∴ a = 7 and b = -8
→ Use the rule above to find the slope of it
∵ The slope of the given line = [tex]\frac{-7}{-8}[/tex]
∴ The slope of the given line = [tex]\frac{7}{8}[/tex]
To find the slope of the perpendicular line to it reciprocal the fraction and change its sign
∴ The slope of the perpendicular line = [tex]-\frac{8}{7}[/tex]
→ Look at the answer to find the equation which has this slope
∴ The equation of the perpendicular line is y = [tex]-\frac{8}{7}[/tex] x - 7
Choose all of the equations for which x=2 is a solution.
In how many years the simple interest on ₹2000 is less than the simple interest on ₹33000 at 5% by ₹50?
[Irrelevant answers will be reported]
Answer:
0.0322580
Step-by-step explanation:
Simple interest : principal * rate * time
(simple interest on 33000) - (Simple interest on 2000) = 50
Let Time = t
2000 * 0.05 * t = 100t
(33000 * 0.05 * t) = 1650t
1650t - 100t = 50
1550t = 50
t = 50 / 1550
t = 0.0322580
Carlos and Ana were asked to find an explicit formula for the sequence -10,-4,2,8,...−10,−4,2,8,...Minus, 10, comma, minus, 4, comma, 2, comma, 8, comma, point, point, point, where the first term should be f(1)f(1)f, left parenthesis, 1, right parenthesis. Carlos said the formula is f(n)=-10+6nf(n)=−10+6nf, left parenthesis, n, right parenthesis, equals, minus, 10, plus, 6, n. Ana said the formula is f(n)=-10+6(n-1)f(n)=−10+6(n−1)f, left parenthesis, n, right parenthesis, equals, minus, 10, plus, 6, left parenthesis, n, minus, 1, right parenthesis. Which one of them is right?
Answer:
Ana is correct
Step-by-step explanation:
Given
[tex]Sequence:\ -10, -4, 2,8[/tex]
[tex]Carlos; f(n) = -10 + 6n[/tex]
[tex]Ana; f(n) = -10 + 6(n-1)[/tex]
Required
Determine who is right?
To do this, we simply test each sequence.
For Carlos:
When n = 1
[tex]f(1) = -10 + 6 * 1 = -10 + 6 = -4[/tex]
When n = 2
[tex]f(2) = -10 + 6 * 2 = -10 + 12 = 2[/tex]
This is incorrect because the first and second term of the sequence are -10 and -4 not -4 and 2
For Ana:
When n = 1
[tex]f(1) = -10 + 6(1-1) = -10 + 6*0 = -10 + 0 = -10[/tex]
When n = 2
[tex]f(2) = -10 + 6(2-1) = -10 + 6*1 = -10 + 6 = -4[/tex]
When n=3
[tex]f(3) = -10 + 6(3-1) = -10 + 6*2 = -10 + 12 = 2[/tex]
When n = 4
[tex]f(4) = -10 + 6(4-1) = -10 + 6*3 = -10 + 18 = 8[/tex]
This is correct.
Hence, Ana is correct
Answer:
Ana is right

Salma used a photocopier to dilate the design for a monorail track system. The figure shows the design and its photocopy: Two irregular quadrilaterals ABCD and EFGH are drawn. EFGH is the photocopy of design ABCD. AB measures 15 meters, DC measures 17 meters. No dimensions are shown on EFGH. The ratio of AD:EH is 1:2. What is the length, in meters, of side GH on the photocopied image? 15 17 30 34
Answer:
The answer is 34
Step-by-step explanation:
The ratio of AD:EH is 1:2, so therefore the other line segments have the same ratio. Using this logic, we see that DC is equal to 17 m, and we need to find GH. All we do now is double the measurement of DC since the ratio of the two shapes is 1:2.
Therefore, 17 * 2 = 34

A school club wants to collect at least 500 canned goods for a school food drive. The club has already collected 30 canned goods
Part A
If 10 club members each collect the same number of canned goods, which inequality represents the minimum number of canned goods, n, each club
member must select for the club to meet the goals?
Answer:
The correct answer is 10n ≥ 470.
Step-by-step explanation:
Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.
They already collected 30 canned goods, therefore we can subtract this quantity from out goal.
500 - 30 = 470
Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.
Hope this helps! :D

What is the slope?
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
Slope is 4.
Step-by-step explanation:
First, we need to find two points in order to find the slope.
Point A (50, 0)
Point B (60, 40)
Next, we have to plug the points in to the slope equation.
[tex]m = \frac{y_{2} - y{1}}{x_{2}- x_{1}}[/tex]
Point A will be [tex](x_{1}, y_{1})[/tex]
Point B will be [tex](x_{2}, y_{2})[/tex].
[tex]m = \frac{40 - 0}{60- 50}[/tex]
[tex]m = \frac{40}{10}[/tex]
[tex]m = 4[/tex]
Therefore, the slope is 4.

current ages
Bill is 8
Jenny is 6
and Phil is 4
the dad is 36
9514 1404 393
Answer:
6
Step-by-step explanation:
Let p, b, j, d represent the ages of Phil, Bill, Jenny, and Dad. We are given the relations ...
b = 2p
j = b -2
2(p +b +j) = d
(p+9) +(b+9) +(j+9) = d+9
_____
Solving the last equation for d, we get ...
(p +b +j) +18 = d
Substituting for the sum of p, b, j in the third equation, we have ...
2(d -18) = d
d = 36 . . . . . . . . add 36-d
Substituting for b and j in the third equation, we get ...
2(p +(2p) +(2p-2)) = 36 . . . . . uses b=2p in the 2nd equation
10p -4 = 36 . . . . . . . . . . . . . . . collect terms
p = 40/10 = 4 . . . . . . add 4; divide by 10
b = 2p = 8
j = b -2 = 6
Jenny's current age is 6.
_____
All of the ages are ...
Bill: 8; Jenny: 6; Phil: 4; Dad: 36
