A scenic train ride has one price for adults and one price for children. One family of two adults and two children pays 1054 Baht for the train ride. Another family of one adult and four children pays 1190 Baht. Find the price x for an adult and the price y for a child?
Answers
Answer:
x = price for adult = 306 Baht
y = price for children = 221 Baht
Step-by-step explanation:
Let
x = price for adult
y = price for children
2x + 2y = 1054 (1)
x + 4y = 1190 (2)
From (1)
x = 1190 - 4y
Substitute x = 1190 - 4y into (1)
2x + 2y = 1054 (1)
2(1190 - 4y) + 2y = 1054
2380 - 8y + 2y = 1054
- 8y + 2y = 1054 - 2380
- 6y = - 1326
y = -1326/-6
y = 221
Substitute y = 221 into (2)
x + 4y = 1190 (2)
x + 4(221) = 1190
x + 884 = 1190
x = 1190 - 884
= 306
x = price for adult = 306 Baht
y = price for children = 221 Baht

A picture is 46 cm by 32 cm. A scale diagram of the picture must fit in a space that is 3 m by 2 m. Which scale would be the most reasonable one to use for the scale diagram?
Answers
Answer:
A picture that is 46cm by 32 cm must fit in a space that is 3m by 2m
First, let's rewrite both of these dimensions in the same units.
Knowing that:
1m = 100cm
Then the dimensions of the space can be rewritten from:
3m by 2m
to:
300cm by 200cm
So, if we enlarge our original picture by a scale factor K, the new dimensions of the picture will be:
K*46cm by K*32cm
Now we just need to find a value of K such that:
K*46cm is something near to 300cm
K*32cm is something near to 200cm
First, we can solve the equation:
K*46cm = 300cm
solving this for K we get:
K = 300cm/46cm = 6.5
While if we solve the equation:
K*32cm = 200cm
we get:
K = 200cm/32cm = 6.25
So we got two possible scale factors.
Which one we should take?
Notice that if we wanted to use the larger one (K = 6.5) for the 32cm side. the new length would be:
32cm*6.5 = 208cm
This is larger than the 200cm of space that we have
Then we can not select the larger option, we can only take the other value:
K = 6.25
Then we can conclude that a reasonable scale factor to use is K = 6.25

Anne bought 9m of ribbon.She used 1/3 of it to wrap some presents and gave 1/2m to her sister.How much ribbon Anne have?
Answers
Answer:
3 meters of ribbon left
Step-by-step explanation:
Since she used 1/3 of the ribbon. Do the following:
1/3 of 9 (Which equates to):
9/3 = 6 (6 meters of ribbon left)
Now do 1/2 of 6, as she gave her sister 1/2 of the remainder.
1/2 of 6 (Which equates to):
6/2 = 3 (3 meters of ribbon left)

the shape of the graph shows a sine graph, which is usually denoted by asinbx+c
a is amplitude/2 = 2/2 = 1
b is the period, 360 = 360/b, b=1
since the graph starts at (0,0), c =0
hence, this graph is 1sin1x = sinx

Answer:
Step-by-step explanation:
This rotation would create a sphere.
If a semi-circle is rotated about the y-axis of the graph, then the resulting three-dimensional shape will be a sphere.
What is a semi-circle?A semicircle is a half-circle formed by a one-dimensional locus of points.
What is a sphere?A sphere is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space.
If a semi-circle is rotated about the y-axis of the graph, then the resulting three-dimensional shape will be a sphere. This is because of the fact that when the semi-circle will be rotated about the y-axis then all the points will be at equal distance in all the directions from the centre.

The opposite side of 60° is: x * sqrt(3)
The opposite side of the 90° is: 2x
We have our side length for 90° so we just have to work backwards
To find our 30° side length we must divide by 2
8/2 = 4
Which means your y = 4
Now that we have our 30° side length we can just multiple it by sqrt(3)
That means your x = 4 sqrt(3)
