Answer:
its either 2 or 4 because a triangle can't change its shape it need to be the same shape
Answer:
2, 3, and 4.
Step-by-step explanation:
The only answer that would result in a non-congruent triangle would be Option 1. It is asking you to dilate by a scale factor of 2 which would make the triangle 2 times bigger. In that case, the triangle to not be congruent.
Reflections, Rotations, and Translations do not change the size of the triangle which means it remains congruent.

Answer:
use area
Step-by-step explanation:
we can't use volume here since we are dealing with the outside part only
so area of a cylinder is =πr²h
our r represents the radius which is diameter/2
r=7.5/2
=3.75m
our h represents height which is 12.5m
so put in our formula
area = π×(3.75)²×(12.5)
=552.2330836m³

Find the surface area and volume of a cube with a cylinder cut out
Cylinder has 1m radius, cube: 6m
Answer:
247.42 m^2 to the nearest hundredth
Step-by-step explanation:
The surfaces area of the side of the cylinder = 2πrh
= 2π(1)(6)
= 12π m^2.
Now we need the surface area of the cube minus the 2 circles at each end of the cylinder
= 6^3 - 2πr^2
= 216 - 2π
So the required surface area
= 12π + 216 - 2π
= 217 + 10π
= 247.4159 m^2
Two prisms are similar and their ratio of similarity is 2:5.
Find the area of a base of the larger prism if the area of a base of the smaller prism is 31 square units.
Round to the nearest hundredth.
help fast please
Answer:
77.5 square units
Step-by-step explanation:
set up a proportion first.
[tex] \frac{2}{5} = \frac{31}{x} [/tex]
then, cross multiply
2x = 155
divide by 2
x = 77.5
The area of the base of the larger prism is approximately 193.75 square units.
How to calculate the area?If two prisms are similar, then their corresponding sides are proportional. Let the smaller prism have a base area of 31 square units, and let the corresponding side of the larger prism have length x.
Since the ratio of similarity is 2:5, we have:
x / s = 5/2
where s is the length of the corresponding side of the smaller prism. Solving for x, we get:
x = (5/2) x s
We know that the area of the base of a prism is given by the formula:
A = s²
Substituting the value of s in terms of x, we get:
A = ((5/2) x s)²
A = (25/4) x s²
Substituting the value of s² in terms of the area of the smaller prism, we get:
A = (25/4) x 31
A = 775/4
A = 193.75 square units
Therefore, the area of the base of the larger prism is approximately 193.75 square units.

What is the angle, in degrees, if the Area is 180 square miles and the radius is 42,240 feet?
Step-by-step explanation:
the area of a circle (all 360°) is
pi×r²
with r being the radius.
the area of a circle segment is just the corresponding fraction of the whole circle.
so the area of a segment of x degrees is
pi×r² × x/360
in our case we know
pi×42240² × x/360 = 180 mi²
we also know that there are 5280 ft in 1 mile.
so, the radius is actually
42240 / 5280 = 8 miles
and therefore our equation resulting in mi² has to use miles and not ft and has to look that way :
pi×8² × x/360 = 180 mi²
pi×64 × x/360 = 180
pi×64 × x = 180×360
pi×x = 180×360/64 = 1012.5
x = 1012.5/pi = 322.2887598...°
so, the angle of the segment of a circle with the area of 180 mi² and the radius of 8 mi is 322.2887598...°

If the diameter of a youth baseball is 2.8 inches and the diameter of an adult softball is 3.8 inches, what is the approximate difference in their volumes? use 3.14 for pi. round to the nearest tenth. recall the formula sphere volume = four-thirds pi r cubed. 1.0 cubic inch 17.2 cubic inches 40.2 cubic inches 137.8 cubic inches
The approximate difference in their volumes is 17.2 cubic inches
Volume of a sphereA sphere is a round solid figure, with every point on its surface equidistant from its centre.
The formula for calculating the volume of a sphere is;
V = 4/3πr³
where:
r is the radius of the sphere
Given the following
diameter of youth ball =2.8in
radius of youth ball r = 1.4in
diameter of adult ball =3.8in
radius of adult ball R = 1.9in
Determine the difference in volume
D = 4/3π(R³ - r³)
Substitute
D = 4/3π(1.9³ - 1.4³)
D = 4/3π(4.115)
D =17.2 cubic inches

Identify the slope and y-intercept of each of the following lines. Then graph each line.
x = -7
Do I mark the graph attached?
Answer:
Below!
Step-by-step explanation:
Since there is a variable (x) on the L.H.S and a constant (-7) on the R.H.S, the line will be a vertical line intersecting the x-coordinate (-7).
~Graph attached
Determining the y-intercept of the line:
Since the line is a vertical line, it's y-intersept is undefined as it will never intersect the y-axis.
Determining the slope of the line:
To determine the slope of the line, pick any two points that is on the line.
⇒ (-7, 0) and (-7, 1)Using the slope formula (y₂ - y₁/x₂ - x₁):
⇒ 1 - 0/-7 - (-7)⇒ 1/-7 + 7⇒ 1/0∴ Any number divided by 0 is undefined
⇒ underfinedThus, the slope and the y-intercept are undefined.
So
line will be parallel to y axis
no y intercept as parallel to y axis means it will never intercept y axis
