In the diagram belowthe length of segment AB is 10, the length of segment AD is 25, and the length of segment AEis 20. What is the length of segment AC? A. 6 B. 10 C. 5 D. 8
Answers
The image of the triangle is missing, so i have attached it.
Answer:
Option D: 8
Step-by-step explanation:
We are given;
AB = 10
AD = 25
AE = 20
We want to find length of AC.
By proportion, we can find length of AC. Thus;
AB/AD = AC/AE
Plugging in the relevant values, we have;
10/25 = AC/20
AC = (10 × 20)/25
AC = 8

If the temperature at which a certain compound melts is a random variable with mean value 135°C and standard deviation 3°C, what are the mean temperature and standard deviation measured in °F? [Hint: °F = 1.8°C + 32.]
Answers
Answer:
The mean in ºF is of 275 and the standard deviation is of 37.4.
Step-by-step explanation:
We apply the conversion formula for both measures, the mean and the standard deviation.
Mean value 135°C
In ºF:
[tex]F = 1.8(135) + 32 = 275[/tex]
Standard deviation 3°C:
In ºF:
[tex]F = 1.8(3) + 32 = 37.4[/tex]
The mean in ºF is of 275 and the standard deviation is of 37.4.

Isabella is bouncing a rubber ball that has a density of 1.5 g/cm3 . The rubber ball has a volume of 113 cm³.
What is the mass of the rubber ball?
Answers
Answer:
The mass of the rubber ball is 169.5g
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for m
m=D*V
In this problem we have
V=113 cm^3
D=1.5 g/cm^3
substitute
m.1.5*113=169.5g

Look at the right-angled triangle ABC.
32°
The square fits exactly inside the triangle.
Work out the sizes of angles x, y and z.
Answers
Answer:
∠x = 90°
∠y = 58°
∠z = 32°
Step-by-step explanation:
he dimensions of the angles given are;
∠B = 32°
Whereby ΔABC is a right-angled triangle, and the square fits at angle A, we have;
∠A = 90°
∠B + ∠C = 90° which gives
32° + ∠C = 90°
∠C = 58°
∠x + Interior angle of the square = 180° (Sum of angles on a straight line)
∠x + 90° = 180°
∠x = 90°
∠x + ∠y + 32° = 180° (Sum of angles in a triangle)
90° + ∠y + 32° = 180°
∠y = 180 - 90° - 32° = 58°
∠y + ∠z + Interior angle of the square = 180° (Sum of angles on a straight line)
58° + ∠z +90° = 180°
∴ ∠z = 32°
∠x = 90°
∠y = 58°
∠z = 32°
Write the slope-intercept form of the equation of the line.

A puppy’s weight increased from 12 pounds to 15 pounds. By what percentage did the puppy’s weight increase?
Answers
=======================================================
Work Shown:
A = old value = 12 pounds
B = new value = 15 pounds
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-12)/12 ] * 100%
C = (3/12)*100%
C = 0.25*100%
C = 25%
The positive C value indicates a percent increase
So effectively, we find the difference or change in weight (B-A) and divide it over the original weight (A). That leads to 0.25 which converts to 25%
Note that,
25% of 12 = 0.25*12 = 3
This says that the puppy gained 3 pounds, which is the value of B-A
Since the puppy gained 3 pounds, the new weight is 12+3 = 15 pounds
-----------
As an alternative, we could divide the two values B over A to find that
B/A = 15/12 = 1.25
Then subtract 1 from this result: 1.25 - 1 = 0.25 = 25%

The ordered pairs (20, -29.5),(21, -31), and (22, -32.5) are points on the graph of a linear equation. Which
of the following graphs show all of the ordered pairs in the solution set of this linear equation?
Answers
The graph that contains the 3 points is the bottom right graph.
Which line contains the 3 points?We want to see which of the graphs contains the 3 ordered pairs:
(20, -29.5),(21, -31), and (22, -32.5)
So we just need to look at the graphs and see which one has these points, notice that as x increases y decreases, so we have a decreasing line.
The slope of the decreasing line is:
a = (-31 + 29.5)/(21 - 20) = -1.5
The graph with this slope is the last one (bottom right, the other decreasing line has a slope of -1). So that is the correct option.

C ≈ 0.00106455765168
Step-by-step explanation:
This is the sum of 13 terms of the geometric series that has 10000C/1.05 as the first term and a common ratio of 1/1.05. The sum S is given by ...
S = a1(1 -r^n)/(1 -r) . . . . a1 is the first term, r is the common ratio
Using the known values, we have ...
100 = (10000C/1.05)(1 -1.05^-13)/(1 -1/1.05))
0.01 = C(1 -1.05^-13)/0.05
C = 0.0005/(1 -1.05^-13) ≈ 0.0005/0.469679
C ≈ 0.00106455765168
Answer:
C ≈ 0.00106455765168
Step-by-step explanation:
100 = (10000C/1.05)(1 -1.05^-13)/(1 -1/1.05))
0.01 = C(1 -1.05^-13)/0.05
C = 0.0005/(1 -1.05^-13) ≈ 0.0005/0.469679
C ≈ 0.00106455765168
