Find the area of a triangle with base of 10 inches and altitude to the base of 16 inches. 135 in 2 160 in 2 80 in 2
Answers
For a triangle with base of 10 inches and altitude of 16 inches, its area will be 80 in² (third option).
Calculation For the Area of the Triangle:
It is given that,
The base of the triangle, B = 10 inches
The altitude from the base of the triangle or height, H = 16 inches
Now, the formula used for finding the area of a triangle is given as follows,
Area, A = (1/2) × B × H
Substituting the given values of B and H in the above formula for area, we get,
A = (1/2) × (10 inches) × (16 inches)
A = 5 × 16 inches²
A = 80 inches²
Thus, the area of the triangle have base 10 inches and altitude 16 inches is 80 square inches.

A plumber charges a flat fee of $73 to visit a home and examine a clogged drain. The plumber charges an additional $25 per hour spent fixing the drain. The total cost, C (in dollars), for fixing a drain that takes h hours is given by the following. C=25h+73 (a) What is the total cost for fixing a drain that takes 5 hours? (b) If the plumber charged a total of $398, how many hours did he spend fixing the drain?
Answers
Answer:
a. The total cost of fixing the drain is $198
b. The plumber spend 13 hours fixing the drain
Step-by-step explanation:
We know the equation is
C=25h+73
C = the total cost
h = the number of hours
Let's solve question a by putting 5 in for h
C=25(5)+73
C = 125 + 73
C = $198
So, the total cost of fixing the drain is $198
Let's solve question b by butting 398 in for c
398=25h+73
325 = 25h
h = 13 hours
So, the plumber spend 13 hours fixing the drain

Given an activity's optimistic, most likely, and pessimistic time estimates of 2, 5, and 14 days respectively, compute the PERT expected activity time for this activity.
Group of answer choices 9 5 7 6
Answers
The PERT expected activity time for this activity is 6 days.
To compute the PERT (Program Evaluation and Review Technique) expected activity time, we can use the formula:
Expected Time = (Optimistic Time + 4 * Most Likely Time + Pessimistic Time) / 6
Using the given values, we have:
Optimistic Time = 2 days
Most Likely Time = 5 days
Pessimistic Time = 14 days
Substituting these values into the formula:
Expected Time = (2 + 4 * 5 + 14) / 6
Expected Time = (2 + 20 + 14) / 6
Expected Time = 36 / 6
Expected Time = 6

Ruth left her home at 9 am and walked to the library. She got to the library at 10 30 am. Ruth walked at a speed of 4 mph. (a) Work out the distance Ruth walked.
Answers
Answer:
she walked 6 miles.
Step-by-step explanation:
We know that Ruth walks at a speed of 4 mph and it took her 1.5 hours to walk from her home to the library (from 9 to 10.30).
We can solve this using a rule of three:
If she walks 4 miles in 1 hour, how many hours did she walk in 1.5 hours?
1 hour 4 miles
1.5 hours x miles
Solving for x we get:
\(x=\frac{1.5(4)}{1} =6\) miles
Thus, she walked a distance of 6 miles
The distance between her home and the library is the number of meters between them.
The distance walked is 6 m
The speed is given as:
\(\mathbf{Speed = 4mph}\)
The time spent walking is calculated as:
\(\mathbf{Time = 10:30am - 9:00am}\)
\(\mathbf{Time = 1.5\ hrs}\)
So, the distance is calculated as:
\(\mathbf{Distance = Speed \times Time}\)
Substitute known values
\(\mathbf{Distance = 4mph \times 1.5hrs}\)
\(\mathbf{Distance = 6m}\)
Hence, the distance walked is 6 m

Another mullet fish's height from the water level can be represented by the equation g(x) = −sin x. At which values on the interval [0, 2π) will the two fish be at the same height above the water?
A: pi/2
B: { 7pi/6 and 11pi/6 }

According to the information, the values on the interval [0, 2\(\pi\)) at which the two fish will be at the same height above the water are: C) {\(\pi\)/2, 7\(\pi\)/6, 11\(\pi\)/6}.
How to find the values at which the two fish will be at the same height?To find the values at which the two fish will be at the same height above the water, we need to equate the two height functions, f(x) and g(x), and solve for x.
f(x) = g(x)2cos²(x) - 1 = -sin(x)2cos²(x) + sin(x) = 1Later, we have to substitute the trigonometric identity sin²(x) + cos²(x) = 1 to simplify further:
2(1 - sin²(x)) + sin(x) = 12 - 2sin²(x) + sin(x) = 12sin²(x) - sin(x) + 1 = 0Next, this equation can be factored as:
(2sin(x) - 1)(sin(x) + 1) = 0To find the values of x, we set each factor equal to zero and solve:
2sin(x) - 1 = 0 => sin(x) = 1/2 => x = \(\pi\)/6, 5\(\pi\)/6 (on the interval [0, 2\(\pi\)))sin(x) + 1 = 0 => sin(x) = -1 => x = 3\(\pi\)/2 (on the interval [0, 2\(\pi\)))According to the above, the values on the interval [0, 2\(\pi\)) at which the two fish will be at the same height above the water are C) {\(\pi\)/2, 7\(\pi\)/6, 11\(\pi\)/6}.
