The red figure is a dilated image of the blue figure. Which diagram shows the correct
center of dilation?
Dilating the blue figure to create the red figure ensures that both figures have different sizes
The correct center of dilation is (d)
How to determine the center of dilation?The center of dilation influences the position of the image of the dilated figure.
For figure 1, the center of dilation would ensure that the red figure is to the left of the blue figureFor figure 2 and 3, the center of dilation would ensure that the red and the blue figure have the same vertexFor figure 4, the center of dilation would ensure that both triangles have the same centerThe 4 diagrams show that both figures have the same center
Hence, the correct center of dilation is (d)

Answer:
angle HMS = 62 degrees
x = 13 degrees
AT = 28
Step-by-step explanation:
angle SHM and angle HMS are both inside the triangle SMH.
We want to find the angle of HMS. We know that the sum of the angles in the triangle adds up to 180 degrees. There are two angles that we already know.
Angle SHM = 28 (given)
Angle HSM = 90 (because it is a right angle which is always 90 degrees, right angles are formed at two perpendicular lines)
Angle HMS = x (we let angle HMS be a variable as we don't know the value for it)
x + 90 + 28 = 180
x = 62 ddegrees
HMS is 62 degrees
TSA is a right angle in triangle AST because it is formed by two perpendicular lines. Right angles always equal 90 degrees.
10x - 40 = 90
10x = 130
x = 13 degrees
AT and HT are both congruent sides. We know this because the figure we are given is a kite. In a kite, we have two pairs of sides that are congruent to each other. HT is congruent to AT while HM is congruent to AM.
So,
8x - 4 = 2x + 20
Subtraact 2 x from both sides
6x - 4 = 20
Add 4 to both sides
6x = 24
Divide 6 on both sides.
x = 4
Plug x back to AT.
AT = 2(4) + 20 = 28
Which situation could be represented by the expression 1.40x?
Answer:
B. the area of a rectangle with side lengths 1.40 and x
Step-by-step explanation:
To find the area of a rectangle, multiply the length by the width.
If 1.40 is the length, x is the width.
1.40×x=1.40x
So B is the correct answer.

A paper cup in the shape of a cone is used to get water from a water cooler. It has a height of 3 inches and a diameter of 22 inches
What is the lateral surface area of the paper cup to the nearest square Inch?
OA 15 square Inches
OB.
19 square Inches
ОС.
14 square Inches
OD. 18 square Inches
We will see that the lateral surface area of the cone is 14 square inches.
How to find the lateral surface area?
We know that for a cone of height H and radius R, the lateral surface of the cone is:
S = 3.14*R*H
In this case, we know that eh height is 3 + 5/8 inches, and the diameter is 2 + 1/2 inches. Remember that the diameter is twice the radius, then:
R = (2 + 1/2) in = (1 + 1/4) in
Replacing that on the surface equation, we will get:
S = 3.14*( (1 + 1/4) in)*(3 + 5/8)in = 14 in^2

find the value of x
Answer:
82•5°
Step-by-step explanation:
[tex]28 + 68.5 + x = 180[/tex]
[tex]x = 180 - 97.5[/tex]
[tex]x = 82.5[/tex]
Here,
let the forth degree of the quadrilateral be y
Then,
90° +90° +68.5° + y =360° (all the interior angle of a quadrilateral is 360°)
or, 248.5+ y=360°
or, y = 360° - 248.5°
or, y= 111.5°
Again, the second angle of the triangle be a
Then,
a=111.5(vertically opposite angle)
Lastly,
29° + 111.5° + x = 180°(all the interior angle of a triangle is 180°)
or, 140.5° + x = 180°
or, x =180° - 140.5°
or, x=39.5°

Which object will have more inertia? Object A that has a mass of 250 grams, Object B, that has a mass of 25,000 grams, or Object C that has a mass of 1,250,000 grams.
1.object a
2.b
3.c
4.all have the same
Answer:
3. Object C.
Step-by-step explanation:
The inertia of an object is the measure of the force required to set it in motion. For two objects to have the same motion, the one with the greater mass will require a proportionately greater force to achieve the same motion.
Object C, with a mass of 1,250,000 grams (1,250 kg) will have the greatest inertia.
