The ratio of boys to girls in a gym class is 5:3. There are 27 girls in the class. How many boys are in the class?
Answer:
There are 45 boys in the gym class.
Step-by-step explanation:
Set up an equation:
Variable x = number of boys in the class
5/3 = x/27
Cross multiply:
5 × 27 = 3 × x
135 = 3x
Divide both sides by 3
45 = x
Check your work:
5/3 = 45/27
5 × 27 = 3 × 45
135 = 135
Correct!

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]

|Calculate the midpoint (-5,5), K(-3,-2)
Answer:
(-4,1.5)
Step-by-step explanation:
Given :-
Two points (-5,5) and (-3,-2)And we need to find out the midpoint of the two points. The midpoint of two points is given by the ,
[tex]:\implies[/tex] Midpoint =( x1+x2/2 , y1+y2/2)
[tex]:\implies[/tex] Midpoint =( -5-3/2 , 5-2/2)
[tex]:\implies[/tex] Midpoint =(-8/2,3/2)
[tex]:\implies[/tex] Midpoint = (-4 , 1.5)
Hence the midpoint of the two points is (-4,1.5) .Here we would be using the midpoint formula to find the co-ordinates of the line segment joining the two given points.
Given points,
(-5,5) and (-3,-2)

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.

El valor numérico de la expresión 〖P(y)=y〗^2-7y+10 para y=2 es: a. P(2)=9 b. P(2)=0 c. P(2)=-2 d. P(2)=-5
Answer:
Opción b, P(2) = 0
Step-by-step explanation:
Tenemos la expresión:
P(y) = y^2 - 7*y + 10
Para encontrar el valor P(2), simplemente debemos remplazar todas las "y" en la expresión de arriba por el valor 2, asi obtenemos:
P(2) = 2^2 - 7*2 + 10 = 4 - 14 + 10 = (4 - 14) + 10 = -10 + 10 = 0
P(2) = 0
La opción correcta es b.
