A photo is reduced with a scale factor of 1 to 3. If the photo is now 4 inches wide, how wide was the original photo? Show the math.
Answers
Answer:
12 inches wide.
Step-by-step explanation:
It is reduced to a 1:3 factor. where 1 is the new length and 3 is the old length. We can write a proportion [tex]1:3=4:x[/tex]. Now, if four numbers are in a proportion we can cross-multiply and we get [tex]1x=3\cdot 4 \rightarrow x = 12[/tex].

Hey there!
According to the figure,
[tex]r = s \: \: \: \: \: \: \overline{pq} = 9[/tex]
So, [tex]m\overline{pq} = \frac{180 \times \overline{pq} }{x \times r} = \frac{180 \times 9}{x \times 5} [/tex]

A city planner wanted to place the new town library at site A. The mayor thought that it would be better at site B. What transformations were applied to the building at site A to relocate the building to site B? Did the mayor change the size or orientation of the library?
The building at site A was translated _______ unit (s)right and _______ unit(s) down, then it was reflected across the x or y (select) - axis.
The size was or was not (select) changed.
The orientation was or was not (select) changed.
Answers
Answer:
2 right, 4 down, y-axis
Step-by-step explanation:
Reflection across the y-axis changes the left-right orientation. Reflection across the x-axis changes the up-down orientation. Translation before the reflection can put the figure in a place so that the reflection gives its final location. Translation does not affect the orientation.
__
We observe that the north-south wall is on the west side of the building at Site A, and on the right side at Site B. That means the orientation was changed left-to-right, so reflection was across the y-axis.
If the reflection occurred last, then the position before reflection must have the northeast corner moved from (-3, 5) to (-1, 1). That is, the x-coordinate is increased by 2, and the y-coordinate was decreased by 4.
The building at site A was translated 2 units right and 4 units down; then it was reflected across the y-axis .

The STEM Club is renting a pavilion at the amusement park.

How many students need to attend if they want to pay under $12 per person? A) 34 B) 35 36 D) 37
Answers
The inverse variation of the STEM club implies that as the number of students increases, the amount reduces
The number of students is 35
How to determine the number of students?An inverse variation is represented as:
[tex]k = xy[/tex]
Where:
k represents the proportionality constant.
x represents the number of students, and y represents the amount
So, we have:
[tex]x_1 * y_1 = x_2 * y_2[/tex]
This gives
[tex]25 * 17 = x_2 * 12[/tex]
Evaluate the product
[tex]425 = x_2 * 12[/tex]
Divide both sides by 12
[tex]x_2 = 35[/tex]
Hence, the number of students is 35

Step-by-step explanation:
Answer:
90yd²
Step-by-step explanation:
Area pf trapezium = 1/2 * (sum of parallel sides) * perdendicular distance b/w them.
Here,
Sum of II sides = 11 + 9yd = 20yd
Perpendicular distance = 18 yd
So, area of trapezium is
1/2 * 20yd * 18yd = 180yd²
As the triangle inscribed is right - angled triangle, area of ∆ = 1/2 * 10yd * 18yd = 90yd²
Shaded area = total area - area of ∆
= 180yd² - 90yd²
= 90yd²

y-80=8/5(x-50)
y-80=8/5x-80
y=8/5x+0
the y-intercept is zero (so place a dot at the origin)
next, go up 8 values and then 5 to the right (5,8), continue to do this process until you have enough points to graph a line. (10,16), (15,24), (20,32)

The length of a diagonal in a square is
32 inches. Find the perimeter of
the square.
Answers
By using Pythagorean theorem we can solve for any of the side lengths of a triangle.
a will be the first side,
b will be the second side,
c will be the hypotenuse
And since the shape is a square, that means a and b will be the same length.
a^2 + b^2 = c^2
a^2 + b^2 = 1024
Since and b are the same, we can combine the left side of the equation to be 2a^2
2a^2 = 1024
Divide both sides by 2
a^2 = 512
Square root both sides
a = 22.6274
We have now solved for the length of one of the sides of the square. Since a square has 4 equal sides, we multiply this by 4 for our answer.
22.6274 x 4 = 90.5096 inches

Answers
The amount of gasoline that was in the tank before refilling it was 11.5 gallons. Due to the above, it lacked 8.5 gallons to refill it again.
How to calculate how many gallons were missing to fill the tank?To calculate how many gallons were left to refill the tank, you need to know how much gasoline was in the tank.
According to the statement, the tank required [tex]8 \frac{5}{10}[/tex] to fill up, then to know how much gasoline it had we must subtract this amount from the maximum capacity of gasoline that the tank requires as shown below:
[tex]8\frac{5}{10}[/tex] = 8.5 gallons
20 - 8.5 gallons
= 11.5 gallons
Based on the above, the number of gallons in the tank was 11.5 gallons of gasoline.

Answer:
89
Step-by-step explanation:
The arc intercepted by the inscribed 45° angle is twice that, 90°. The angle at x is half the sum of the intercepted arcs, so is ...
x = (90° +88°)/2
x = 89°
_____
Alternate solution
The inscribed angle intercepting the 88° arc will have half that measure, so is 44°. The triangle's exterior angle x will be equal to the sum of the remote interior angles:
x = 45° +44° = 89°

An acute angle is less than 90°.
Answers
An acute angle is less than 90° is shown in the second option. Hence, the second option is correct.
What is an acute angle?Acute angles are those that are smaller than 90° and fall between 0° and 90°; they are referred to as such. For example, temperatures of 60°, 30°, 45°, and others. An acute triangle is a triangle whose all internal angles are less than 90 degrees. An equilateral triangle is called an acute triangle if its internal angles measure 60°.
There are various types of angles, most commonly they are :
Acute angleRight angle Obtuse angleIn the second option, the circle is void, which means the angle is less than 90°. As we compare this with the first option the circle is filled, which means that the angle is equal to 90° which means that it is a right angle.
