Find the perimeter of the figure to the nearest hundredth.
Answer: 90.75 mm
Step-by-step explanation:
Given
The radius of the hemisphere is 16 mm
length of the inclined sides are 20 mm
The perimeter of the figure is the sum of the length of two inclined sides and a semi-circle circumference
[tex]\Rightarrow \text{Perimeter P=}\dfrac{2\pi r}{2}+2\times 20\\\\\Rightarrow P=\pi \times 16+40\\\Rightarrow P=50.75+40\\\Rightarrow P=90.75\ mm[/tex]

What is the area of the square?
What’s the area of the circle
Answer:
Square: 144 m²
Circle: 113.04 m²
Step-by-step explanation:
The formula for area of a square: side × side.
The formula for area of a circle: r²π (radius × radius × pi)
**SQUARES HAVE EQUAL SIDES**
As shown in the photo, the side lengths of the square are 12.
side × side
12 × 12 = 144
Therefore, 144 m² is the area of the square.
-------------------------------------------------------------------------------------------------------------
The diameter of the circle is 12 as well.
But, to find the area of the circle, we need the radius.
To find the radius of a circle, divide the diameter by 2.
12 ÷ 2 = 6.
6 is the radius.
Now we plug the numbers into the equation.
**3.14 IS A SUBSTITUTE FOR PI**
r²π (radius × radius × pi)
6²π (6 × 6 × 3.14) = 113.04
Therefore, 113.04 m² is the area of the circle.

Condense the expression to a single logarithm. 3 log subscript 5 10 - 12 log subscript 5 7
Answer:
A is correct
Step-by-step explanation:
Mathematically from logarithmic laws, we have it that;
x log a = log a^x
and also;
log a - log b = log (a/b)
So we have;
log 5 10^3 - log 5 7^12
and finally log 5 (10^3/7^12)

Answer:
32.0087878558 units
Step-by-step explanation:
Let the Triangle be ABC
By Pythagoras Theorem:
(BC)² = (AB)² + (AC)²
(BC)² = 13² + 29.25²
(BC)² = 169 + 855.5625
(BC)² = 1024.5625
BC = √1024.5625
BC = 32.0087878558
Therefore, x = 32.0087878558

What is the diameter of a cone with height 8 m and volume 150 pi m3 ?
A. 7.5 m
B. 5V3 m
o C. 7.573 m
D. 15 m
Answer:
V = pi*r^2*h
V = 150 m^3
h = 8 m
150 = pi*r^2*8
Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.
V = 1/3 pi r^2 h
Diameter of the cone is 15 m. So, option D is correct.
What is meant by solid shape ?Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.
Here,
Volume of the cone is given by,
V = 150[tex]\pi[/tex] m³
Height of the cone, h = 8 m
We know, the equation for the volume of a cone is,
V = 1/3[tex]\pi[/tex]r²h
where r is the radius and h is the height of the cone.
So,
(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]
r²x 8 = 3 x 150 = 450
r² = 450/8
r² = 56.25
r = 7.5 m
Therefore, diameter of the cone,
d = 2r
d = 2 x 7.5
d = 15 m
Hence,
Diameter of the cone is 15 m.

Two trains start from Fort Worth traveling at the same speed. The trip for Train W takes 20 hours, while the trip for Train Z takes 25 hours. If the city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to, how far will Train Z travel in total to reach its destination?
Answer:
= x/20=x+400/25
Distance traveled by Train W = 1600 miles
Distance traveled by Train Z = 2,000 miles
Step-by-step explanation:
Time taken for Train W to complete a trip = 20 hours
Time taken for Train Z to complete a trip = 25 hours
The city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to.
both trains have same speeds and start from same location.
To find the distance in total each train travels.
Solution:
Let length of the trip of Train W be = xx miles
Speed of Train W can be given as :
⇒ \frac{Distance}{Time}
Time
Distance
⇒ \frac{x}{20}\ miles/h
20
x
miles/h
So, the length of the trip of Train Z will be = (x+400)(x+400) miles
Speed of Train Z can be given as :
⇒ \frac{Distance}{Time}
Time
Distance
⇒ \frac{x+400}{25}\ miles/h
25
x+400
miles/h
Since the speeds are same, so the equation to find xx can be given as:
⇒ \frac{x}{20}=\frac{x+400}{25}
20
x
=
25
x+400
Solving for xx
Multiplying both sides by 100 to remove fractions.
⇒ 100\times \frac{x}{20}=100\times \frac{x+400}{25}100×
20
x
=100×
25
x+400
⇒ 5x=4(x+400)5x=4(x+400)
Using distribution.
⇒ 5x=4x+16005x=4x+1600
Subtracting both sides by 4x4x
⇒ 5x-4x=4x-4x+16005x−4x=4x−4x+1600
⇒ x=1600x=1600
Thus, Distance traveled by Train W = 1600 miles
Distance traveled by Train Z = 1600+4001600+400 = 2,000 miles
