Answer:
AC = 28
Step-by-step explanation:
ΔADB ≈ ΔDBC
DC / BC = AD / 15
16 / 20 = AD / 15
cross-multiply:
20AD = 240
AD = 12
AD + DC = AC
12 + 16 = AC
28 = AC

Answers
Answer:
132.5 degrees. Check to see if there is missing information in the question or any mistakes.
Step-by-step explanation:
Supplementary angles = 180 degrees
180 - 47.5 = 132.5
A grain silo is shown below:
Grain silo formed by cylinder with radius 6 feet and height 168 feet and a half sphere on the top
What is the volume of grain that could completely fill this silo, rounded to the nearest whole number? Use 22 over 7 for pi.
Answers
Answer: 13750+262=14,012 ft^3
Step-by-step explanation:
Hello!!!
Find the volume of the bottom and top separately and then add them. Cylinder volume is the area of the bottom times the height (22/7)(5^2)•175=13750 ft^3
The volume of a sphere isV=(4/3)(22/7)r^3where r is the radius. also 5 since it fits on the cylinder. Also we only want half the sphere so useV=(2/3)(22/7)•5^3=261.9 ft^3 round upto 262. Now add together 13750+262=14,012 ft^3

Este año en la escuela de inglés, el numero de usuarios de intagram ha alcanzado la cifra de 2604 alumnos, lo que supone un aumento del 24% respecto del año pasado. ¿ cuantos usuarios habia el año pasado?
Answers
Answer:
the number of users in the last year is 2,100
Step-by-step explanation:
The computation of the number of users in the last year is shown below:
Given that
The users are 2604 that are increased to 24% as compared with the last year
So, the users in the last year is
= 2604 ×100 ÷ 124
= 2,100
Hence, the number of users in the last year is 2,100

============================================================
Explanation:
Refer to the diagram below. I've added the variables b, c and d to the drawing you posted.
The variable b is an inscribed angle, while variables c and d are arc measures.
For any inscribed quadrilateral, the opposite angles always add to 180. They are supplementary angles. This means the 110 degree angle and the angle b add to 180, so,
110+b = 180
b = 180-110
b = 70
Inscribed angle b is 70 degrees.
Next, we apply the inscribed angle theorem. This theorem says that the inscribed angle doubles in value to get its corresponding central angle measure (and therefore it's arc measure as well).
In other words, inscribed angle b = 70 doubles to 2*70 = 140 degrees. This represents the combination of arcs c and d. Therefore, c+d = 140. Note how inscribed angle b cuts off this longer arc.
We don't need to find the measure of arc c or arc d individually. We just need to find the measure of arc 'a'.
The four arc measures (161, a, c and d) all combine to a full 360 degree circle. Let's add those four parts, and set that equal to 360. We'll keep in mind that c+d = 140 as well.
So...
a+c+d+161 = 360
a = 360-161 - (c+d)
a = 360-161 - (140) ..... replaced "c+d" with "140"
a = 59
Arc 'a' is 59 degrees
How many roots does the equation 3x² = 1 - 7x have and what is the nature of the roots
Answers
Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots

The bear population in Canada was 380,000 in the year 2015, and environmentalists think that the population is increasing at a rate of 2.5% per year.
Consider the function that represents the exponential growth of the bear population in Canada.
Part A: Defines a variable for the function and state what the variable represents.
Part B: What is a reasonable domain for the situation?
Part C: Write the function that represents the exponential growth of the bear population.
Part D: What will the bear population estimated to be in 2050?
Answers
Answer:
The population of Bear in 2050 is 4750000
Step-by-step explanation:
A) The exponential growth equation for bear is as follows -
dN/dT = rmax * N
Where dN/dT = change in population
rmax is the maximum rate of change
N = Base population
B) Here the per capita rate of increase (r) will always be a positive value irrespective of the and hence we will assume this population to be growing exponentially.
C) dN/dT = rmax * N
D) dN / 5 = 2.5 * 380,000
dN = 5*2.5 * 380000
= 4750000

Translate into an equation: Twenty-six more than the product of a number and
17 is -42.
Answers
“the product of a number and 17” = 17n
“twenty six more than” = + 26
And if the next question has you solve it:
17n + 26 = -42
Subtract 26 from both sides
17n = -68
Divide both sides by 17
