Answer:
20in^2
Step-by-step explanation:
Since you multiply the original area of the triangle by the scale factor to get the new area, you can find the original area (before dilation) by dividing the dilated triangle's area by the scale factor. Since 100 is the area of the dilated triangle, and 5 is your scale factor, you do 100/5 to get the area of the triangle before it was dilated.
z= -91 +14.6i
is the real part of z?
What is the imaginary part of z?
Answer:
- 91 and 14.6
Step-by-step explanation:
Given a complex number z = a + bi
Then a is the real part and b the imaginary part
Given
z = - 91 + 14.6i , then
- 91 is the real part and 14.6 the imaginary part

A segment is m units long. Find the distance between the midpoints of the first and the last parts in each case. a The segment is divided into three equal parts
Answer:
(2/3)m units
Step-by-step explanation:
The segment is m units long. After dividing it into 3 three equal parts, each part is m/3 units long. The midpoint of the first part is located at (m/3)/2 = m/6 units from the beginning of the segment. The midpoint of the last part is located at (2/3)m + m/6 = (5/6)m units from the beginning of the segment. Then, the distance between the midpoints of the first and the last parts is (5/6)m - m/6 = (2/3)m units
Line can be divided into segments.
The distance between the two midpoints is 2m/3
The length of the segment is given as:
[tex]\mathbf{Length = m}[/tex]
The length of each segment, after dividing them into 3 segments is:
[tex]\mathbf{Segment = \frac m3}[/tex]
The midpoint of the first segment is:
[tex]\mathbf{First= \frac m6}[/tex]
The midpoint of the third segment is the sum of the first two segments, and the half a segment
So, we have:
[tex]\mathbf{Third = \frac m3 + \frac m3 + \frac m6}[/tex]
[tex]\mathbf{Third = \frac{5m}{6}}[/tex]
So, the distance between the two midpoints is:
[tex]\mathbf{Distance = \frac{5m}{6} - \frac{m}{6}}[/tex]
[tex]\mathbf{Distance = \frac{5m - m}{6}}[/tex]
[tex]\mathbf{Distance = \frac{4 m}{6}}[/tex]
[tex]\mathbf{Distance = \frac{2m}{3}}[/tex]
Hence, the distance between the two midpoints is 2m/3

If two sides of a triangle are 6 and 16, what is the range of the possible lengths of the third side?
Answer:
10 < x <22
Step-by-step explanation:
The smallest side must be larger than the difference of the two sides
16-6 = 10
x>10
The largest side must be smaller then the sum of the two sides
6+16 =22
x< 22
Put this together
10 < x <22
Answer:
10 < c < 22
Step-by-step explanation:
Remember the Triangle Inequality Theorem.
For a triangle with sides a, b, and c:
- a + b > c
- a + c > b
- b + c > a
Let's arbitrarily say a = 6 and b = 16. Then:
a + b > c
6 + 16 > c
c < 22
a + c > b
6 + c > 16
c > 10
b + c > a
16 + c > 6
c > -10
Thus, the range of possible lengths of the third side, c, is 10 < c < 22.
A group of 140 high school students were asked, "Do you play a musical instrument?" The results are shown in the table below. If a musician is selected at random, what is the probability that the individual is a female student?
Males - only 24 play instruments and 41 don't
Females - only 43 play instruments and 32 don't
A. 43/140
B. 43/67
C. 43/75
D. 15/28
ANSWER:
A
Step -by -step verification:
Total number of female students that play instruments
Total number of students =43/140
If a musician is selected at random, the probability that the individual is a female student is; 15/28
How to Find the Probability?
We are given;
Total Number of High school students surveyed = 140
Number of males that play instruments = 24
Number of males that don't play instruments = 41
Number of females that play instruments = 43
Number of females that don't play instruments = 32
Thus, If a musician is selected at random, the probability that the individual is a female student is;
P(Female Student) = (43 + 32)/140 = 75/140 = 15/28

Find the total volume of the figure.
Answer:
The Volume is 2,200
Step-by-step explanation:
10+8.8= 18.8
13.7+25= 38.7
18.8+38.7= 57.5
This is the incorrect way
__________________________________________________
Correct way:
Volume= L×H×W
25 × 8.8 × 10 = 2,200
The total volume of the figure is 693 m³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a composite figure consisting of a triangular pyramid and a triangular prism.
Total volume of the figure = Volume of pyramid + volume of prism
Volume of the pyramid = 1/3 × base area × height
Base area = 1/2 × √(13.7² - 8.8²) × 8.8
= 1/2 × 10.5 × 8.8
= 46.2 m²
Volume of the pyramid = 1/3 × 46.2 × (25 - 10)
= 231 m³
Volume of the prism = base area × height
= 46.2 × 10
= 462 m³
Total volume = 231 m³ + 462 m³ = 693 m³
Hence the total volume is 693 m³.
