Answer:
3.2mm ^3
Step-by-step explanation:
First find the scale factor to get the height of the smaller figure
SF= 1/5 or 0.2
Then use the Volume equation for triangular pyramid 1/3*(base area)*(height)
Your equation should look like this:
1/3 (4)(2.4)
9.6/3
Volume= 3.2 mm ^3

A right rectangular prism has base dimensions of 2 1 /10 ft wide and 4 1/ 5 ft long. If the height of the prism is 3 1 /2 ft, what is the volume of the prism?
Answer:
2 1/10 x 4 1/5 x 3 1/2 = 30 87/100 feet
(Remember multiply one by one first multiply 2 1/10 x 4 1/5 = 8 41/50
then multiply 8 41/50 with 3 1/2 to get = 30 87/100 is your answer)
Step-by-step explanation:
Just multiply the given lengths. A 3 dimensional shape has to be given 3 sides in order to know the area/volume: Length x Width x Height

A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Answer:
Lateral Surface Area = 94.25 cm²
Surface area = 150.8 cm²
Step-by-step explanation:
A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Step 1
We have to find the radius of the cylinder
We are told in the question that:
The circumference of one circle is 18.84 cm
Circumference of a circle = 2πr
18.84cm = 2πr
r = 18.84/2π
r = 2.9984791279cm
Approximately the radius = 3cm
Step 2
We find the Lateral Surface Area of the Cylinder
The formula =2πrh
r = 3cm
h = 5cm
=2×π × 3 × 5
= 94.24778 cm²
Approximately = 94.25 cm²
Step 3
We find the Surface Area of the Cylinder
The formula =2πr(r + h)
r = 3cm
h = 5cm
=2×π × 3 × 5(3 + 5)
= 150.79645 cm²
Approximately = 150.80 cm²

Answer:

Step-by-step explanation:
At a party there are 90 people.
48 are women and 42 are men.
Some women leave.
Some men arrive.
The ratio of women to men is now
10:11
Are there now more than 90 people at the party?
Show working to support your answer.
Answer:
No
Step-by-step explanation:
Originally:
48:42
If some leave and some arrive = 10:11 given in question
So 48- 8 leave = 40 women
Therefore 42+2=44
Now the ratio is 40:44 (Actual amount of people)
When you simplify/ divide by 4 = 10:11
Total amount of people is 40+44= 84 which is less than 90

Factor Completely
a^2 - a - 20
Answer:
[tex]\left(a+4\right)\left(a-5\right)[/tex]
Step-by-step explanation:
Break the expression into groups.
=(a^2+4a)+(−5a−20)
Factor out a from a2+4a: a(a+4)
Factor out −5 from −5a−20: −5(a+4)
=a(a+4)−5(a+4)
3. Identify the pair of angles as complementary, supplementary, both, or neither.
a. supplementary
b. complementary and supplementary
c. neither
d. complementary
Answer:
D) Complementary
Step-by-step explanation:
Angles are complementary if they add up to 90°. The image shown showcases that the angles are 90° because of the box on the corner.
Supplementary means it adds up to 180° which would be a straight line, this is not the case where this is shown.

Answer:
390%
Step-by-step explanation:
We are given the mixed fraction:
3 9/10
Convert to improper fraction
39/10
Converting this to Percentage :
39/10 × 100
= 3900/10
= 390%
Therefore: 3 9/10 as a percentage = 390%

Let f (x) = x2 +1.
Let g(x) = (x + 2)2 +1.
Which statement describes the graph of g(x) with respect to the graph of f(x)?
It is translated left 2 units.
It is translated right 2 units.
It is compressed vertically by a factor of 2.
It is compressed horizontally by a factor of 2.
Answer:
For this transition of equations, the graph of g(x) will be translated left 2 units with respect to the graph of f(x), so your answer choice will be A.
Step-by-step explanation:
In this equation, g(x) is changed by adding 2 and closing part of the equation in parenthases, this results in the translation 2 units left, which can be proven by a graph and my answer.

Hey there!
2(12)3/2
= 2(12)(3/2)
= 24(3/2)
= 24/1 * 3/2
= 24(3) / 1(2)
= 24 + 24 + 24 / 1 + 1
= 48 + 24 / 2
= 72 / 2
= 72 ÷ 2 / 2 ÷ 2
= 36 / 1
= 36 ÷ 1
= 36
Therefore, your answer is: 36
Good luck on your assignment & enjoy your day!

Which equation represents a line which is parallel to the line x+4y=-20x+4y=−20?
Answer:
y=7x+3, y=7x−6
Write the slope-intercept form of the line with the given slope and point.
m = -2; (5, 1)
Answer:
y = -2x + 11
Step-by-step explanation:
If you already have the slope, all you need to do is find the y-intercept.
y = -2x + b
1 = -2(5) + b
1 = -10 + b
11 = b
The equation is y = -2x + 11
4 What is the slope of the line represented by the
table of values below?
Answer:
(c) or 10 is the answer
Step-by-step explanation:
In order to find slope you have to follow the formula
(y2-y1) / (x2-x1)
That would give you the slope which in this case is 10.
