Answers
Answer:
x = 8.92 units
Step-by-step explanation:
From the triangle given in the picture,
Missing side of the triangle is the opposite side of the angle measuring 28°
And hypotenuse measuring 19 units has been given.
So, we will use sine ratio for the given angle.
sin(28°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(28°) = [tex]\frac{x}{19}[/tex]
x = 19sin(28°)
x = 8.92 units

Step-by-step explanation:
A line can be defined by any two points on the line andhas the form
y=mx+b
Where m=slope and b=y intercept (value of y when x=0)
Slope is defined as
m=(y2-y1)/(x2-x1), we have points (0,7) and (1,4)
m=(4-7)/(1-0)
m=-3/1
m=-3 so the line is thus far
y=-3x+b, since we have the point (0,7) we know that b=7 so the line is
y=-3x+7

At an amusement park, the cost of an adult's ticket is $22.50, and the cost of a child's ticket is $12.50. A group of 10 people purchased tickets for the amusement park, and paid a total of $155.00, excluding tax. How many children were in the group? How many adults were in the group?
Answers
Answer:
is there any more information you could give?
Step-by-step explanation:
**i promise to provide a real answer**
Answer:
7 children and 3 adults
Step-by-step explanation:
We should set up a system of equations for this problem, so let's say that:
x represents the number of children
y represents the number of adults
We know there is a total of 10 people, so:
x + y = 10
We also know that each adult had to pay $22.50 and each child had to pay $12.50. Their total amount paid is $155.00, so:
12.50x + 22.50y = 155.00
Simplifying this a bit:
12.5x + 22.5y = 155
Now, we can use the substitution method to solve this system of equations:
x + y = 10
y = 10 - x
12.5x + 22.5y = 155
12.5x + 22.5 (10 - x) = 155
12.5x + 225 - 22.5x = 155
12.5x - 22.5x = 155 - 225
-10x = 155 - 225
-10x = -70
x = [tex]\frac{70}{10}[/tex]
x = 7 children
Now we substitute back into the system of equations:
x + y = 10
7 + y = 10
y = 10 - 7
y = 3 adults
Pyramid A has height 5 1/2, and Pyramid B has height 2 3/4. A and B are similar. What is the ratio of their:
Lateral areas?
Volumes?
Answers
Answer:
Lateral areas have ratio of 4:1
Volumes have ratio of 8:1
Step-by-step explanation:
There is a rule in 3D geometry that when two solids are similar, and their edges are in the ratio of [tex]a:b[/tex], the ratio of any surface area type measure is always [tex]a^2:b^2[/tex] this includes the lateral area, which is just a surface area minus the base, which is not important for this problem. The ratio of volumes of those similar solids is in the ratio of [tex]a^3:b^3\\[/tex].
Now, to solve this, we need to find the ratio of any corresponding length of these similar pyramids. We have both the heights, so if we form a ratio of [tex]\frac{5\frac{1}{2} }{2\frac{3}{4} }[/tex] which if you simplify it, it is [tex]\frac{5.5}{2.75}[/tex], which is [tex]2[/tex]. The ratio of the heights are [tex]2:1[/tex].
Now we can apply those rules to this ratio, the ratio of lateral areas would then be [tex]2^2:1^2[/tex], which is [tex]4:1[/tex]. the ratio of volumes would be [tex]2^3:1^3[/tex], which is [tex]8:1[/tex]

In 3D geometry, diagonal lines are two lines that do not intersect and are not parallel. A simple example of a pair of diagonal lines is a pair of lines that pass through the opposite edge of a regular tetrahedron.
Can diagonal lines be parallel?Some pairs of diagonal lines are also parallel. This is incorrect. By definition, diagonal lines are on different planes and parallel lines are on the same plane. The two lines can be diagonal or parallel (or both), but not both.
The position of the twist is two lines that do not intersect and are not parallel to each other. Diagonal lines can only exist in dimensions higher than 2D space. They do not have to be coplanar. That is, such lines are in different planes. In a two-dimensional space, two straight lines can intersect or run parallel to each other.

Question
( 10 + 5x )7
Lets solve this easily.
So, basically, 10 + 5x is 15 but we still didn't
get rid of the x so therefore it's still 15x and then there's 7 so we multiply 15 x 7 giving us 105x.
Hence, the answer is.
(C), 70 + 35x is the answer.
