The length of a diagonal in a square is
32 inches. Find the perimeter of
the square.

Answers

Drawing a diagonal line through a square or rectangle makes 2 right triangles. The line drawn will be the hypotenuse of the triangles, which is the longest side.

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

what’s the difference in the y-values of two point on a line called

Answers

The rise is the vertical distance between the two points, which is the difference between their y-coordinates. That makes the rise y2 − y1. The run between these two points is the difference in the x-coordinates, or x2 − x1. Since slope equals rise over run, the slope of the line is y2 − y1 over x2 − x1.

Answer:

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°

I need help finding the equation and graphing it.

Answers

Step-by-step explanation:

First find the slope with the equation y/x

80/50=8/5 (you want this in fraction form)

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)

1. Crestside Ambulance Service has a van with a 20 gallon fuel tank. To fill the tank required 8
5/10 gallons. How many gallons were in the tank before refueling?

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.

An acute angle is less than 90°.

Answers

the answer would be B less than is an open circle and to the left

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 angle

In 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.

So, this concludes that the second option is correct.

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 .

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

Calculate the shaded area

Answers

Answer:

116 cm²

Step-by-step explanation:

area shaded = total area - area not shaded

πr² is the area of a circle

total area = πr² = π*(6.5cm)² = 132.732289614 cm²

area not shaded = πr² (note the radius is 2.3cm for the non-shaded portion) = π*(2.3cm)² = 16.6190251375 cm²

area shaded = total area - area not shaded = 132.732289614 cm² - 16.6190251375 cm² = 116.113264476 cm² ≈ 116 cm²

= πr²h + 2πr²

= (3.14 × 4² × 7) + (2 × 3.14 × 4²)

= 351.68cm + 100.48cm
