AB is parallel to ED.
ACD and BCE are straight lines.
AB = 8 cm
AC = 4.8cm
BC = 6.4cm
ED = 20 cm
Work out the length of BE.
Answer:
BE = 22.4 cm
Step-by-step explanation:
Δ CAB and Δ CDE are similar , then ratios of corresponding sides are equal, that is
[tex]\frac{CB}{CE}[/tex] = [tex]\frac{AB}{DE}[/tex] , substitute values
[tex]\frac{6.4}{CE}[/tex] = [tex]\frac{8}{20}[/tex] ( cross- multiply )
8 CE = 128 ( divide both sides by 8 )
CE = 16 cm
Then
BE = BC + CE = 6.4 + 16 = 22.4 cm

A sphere has a radius of 12 inches. A second sphere has a radius of 9 inches. What is the difference of the volumes of the spheres?
The volume of the larger sphere is _____π cubic inches greater than the volume of the smaller sphere.
Answer:
1332 will be the correct answer...
Step-by-step explanation:
first sphere:2304π
second sphere:972π
2304π - 972π = 1332π
Answer:
Solution given;
for sphere
radius [r]:12inches
another
radius [R]:9inches
Now
difference in volume of sphere:
volume of sphere of having radius [r-R]
=[tex] \frac{4}{3} πr³[/tex]-[tex] \frac{4}{3} πR³[/tex]
=[tex] \frac{4}{3} π[/tex](12³-9³)
= 1332π cubic inches
The volume of the larger sphere is ___1332__π cubic inches greater than the volume of the smaller sphere.

The diagram shows a solid triangular prism. Height 6cm width 4cm length 10cm the prism is made from wood with a density of 0.8 g/cm3 work out the mass of this prism
Answer:
Step-by-step explanation:
The mass of the given triangular prism with a density of 0.8 g/cm³ is 96 grams.
What is the volume of a prism?The volume of a prism is the total space occupied by it.
What is the density of a prism?The density of a prism is the mass occupied by the 1 cubic unit volume of the prism. The formula for the density of a prism is:
Density = Mass/Volume
How do we solve the given question?In the question, we are given a triangular prism of height 6cm, width 4cm, and length 10cm. Its density is given as 0.8 g/cm³.
We first find the volume of the prism.
The volume = Area of triangle*length = ((1/2)*6*4)*10 cm³ = 120 cm³.
Let the mass of the prism be m grams.
We know the density of the prism is given by the formula,
Density = Mass/Volume
or, 0.8 = m/120
or, m = 120*0.8
or, m = 96
∴ The mass of the given triangular prism with a density of 0.8 g/cm³ is 96 grams.

What is the height of the cone below?
The height of the cone is h = 27
Formula:-
Step 1:-
The volume of the cone is V=\frac{1}{3} (base)(height)V=31(base)(height)
Given volume is V= 45 in^ 3
Given base of the cone is B= 5 in^2
Step 2:-
by using formula, we get solution
45 = \frac{1}{3} (5)(h)45=31(5)(h)
cross multiplication, we get
\frac{45 x 3}{5} =h545x3=h
now simplification, the height of the cone is h = 27
sauce: brainly
Answer:
27 in.
Step-by-step explanation:
Firstly, let's look at what we do know. We need to find the height of a cone and we know the area of the base (B) and we know the volume of the cone.
The first step is to determine the radius of the base, which we can use later.
The area of a circle is A = π r^2, so when we plug in the given information
5 = π r^2
And now we can solve for the radius
5/π = r^2
√(5/π) = r
r = 1.26
Now that we have the radius of the base, we can find the height of the cone using the volume formula.
V = π r^2 (h/3)
45 = π (1.26)^2 (h/3)
45 = π (1.59) (h/3)
45/(1.59π) = h/3
9.01 = h/3
3(9.01) = h
h = 27 in
The sum of 5 and y is greater than or equal to 7
Answer:
5 + y ≥ 7
Step-by-step explanation:
"The sum of 5 and y"
The sum of two items will be the two items added, and in this case, it is 5 and y, or
5 + y.
"Greater than or equal to 7"
Here, use the symbol, ≥, and 7.
≥ 7
Combine those to get the final equation:
5 + y ≥ 7.
