The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle
Step-by-step explanation:
use the above picture as a reference and solve
Answer:
36°
Step-by-step explanation:
So, the angle measure of x+15 is 36 because x = 21
The angle measure of 3x-9 is 54, but this is bigger than the one before.
So, the smallest angle is 36

Answer:
y=-1x-8
Step-by-step explanation:
Variables y and x have a proportional relationship, where y = 18 when x = 2.
What is the value of x when y = 36?
Answer:
[tex]\huge\boxed{\sf x = 4}[/tex]
Step-by-step explanation:
Given that:
[tex]y \propto x[/tex]
Converting proportionality into equality
[tex]y = kx[/tex] ----------------(1)
y = 18 when x = 2
Put it in Eq. (1)
[tex]\displaystyle 18 = k(2)\\\\Divide \ both \ sides \ by\ 2\\\\\frac{18}{2} = k\\\\9 = k\\\\ \boxed{k = 9}[/tex]
Now,
x = ? when y = 36
Put it in Eq. (1)
[tex]36 = (9) x\\\\Divide \ both \ sides \ by \ 9\\\\36 / 9 = x\\\\4 =x \\\\\boxed{x = 4}\\\\\rule[225]{225}{2}[/tex]

please help me figure out how to solve the problem below:
the problem below is asking how to find the surface area of the cylinder. please leave an explanation on how to solve it.
formula: 2(3.14)(r)^2 + 2(3.14)(r)
r: radius
Answer:
3315.84mm^2.
Step-by-step explanation:
We calculate the diameter of the base of the cylinder using Pythagoras:
40^2 = d^2 + 32^2
d^2 = 40^2 - 32^2 = 576
d = sqrt 576 = 24 mm.
So the radius = 1/2 diameter = 12 mm.
The surface area
= 2(3.14)(12)^2 + 2(3.14)(12)(32)
= 904.32 + 2411.52
= 3315.84.
A point has the coordinates (m, 0) and m ≠ 0.
Which reflection of the point will produce an image located at (0, –m)?
a reflection of the point across the x-axis
a reflection of the point across the y-axis
a reflection of the point across the line y = x
a reflection of the point across the line y = –x
Therefore the reflection of the point (m,0)and m≠0 will produce an image located at (0,-m) when reflection occurs across the line y=(-x).
Answer:
a reflection of the point across the line y = –x
Step-by-step explanation:
Let m = 5.
Graph (5, 0).
Then graph (0, -5).
Then draw the line y = -x.
You will see that the line y = -x is the axis of symmetry for the two points.
Answer:
a reflection of the point across the line y = –x

Answer:
m<3 = 80
Step-by-step explanation:
We know that the sum of all the angles in a triangle is 180.
Thus, we can find the m<3 using the equation 180 - (70 + 30) = m<3
Simplifying gives us m<3 = 80
Answer:
B .80
Step-by-step explanation:
all interior angles in a triangle=180
180-(70+30)
180-100

Natalie painted three portraits of a 15 minutes at that rate how many would she paint in 10 minutes
Answer:
2 portraits
Step-by-step explanation:
since she painted 3 in 15 minutes, it means that she took 5 minutes on each portrait. If Natalie were to paint portraits for 10 minutes she would paint 2 portraits
3p in 15min = 1p in 5min = 2p in 10min

Answer:
x^3 -4x^2 +12x -27
Step-by-step explanation:
Use the distributive property.
= (x^2 -x +9)(x) +(x^2 -x +9)(-3)
= x^3 -x^2 +9x -3x^2 +3x -27
= x^3 -4x^2 +12x -27 . . . . . collect terms

Help pls!! Determine whether each value is greater for function Q, the same for both functions, or greater for function R
The following conclusion about both functions are:
The initial value for function R (3) is greater than that for function Q (-2).The rate of change for function Q (3) is greater than that for function R (1/3).What is a Linear Function?A linear function is modelled as, y = mx + b
b is initial valuem is the rate of change = change in y/change in x.Function Q:
y = 3x - 2
Initial value (b) = -2
Rate of change (m) = 3
Function R:
Initial value = 3
Rate of change = 1/3
Therefore, the following conclusion about both functions can be made:
The initial value for function R (3) is greater than that for function Q (-2).The rate of change for function Q (3) is greater than that for function R (1/3).Learn more about linear functions on:

A country’s population in 1991 Was 211 million in 1998 it was 215 million estimate the population in 2012 using the exponential growth formula
Answer:
The population in 2012 is estimated in approximately 223 million people
Step-by-step explanation:
Exponential Growth
The formula for exponential growth of a variable P at the growth rate r, as time t goes on in discrete intervals, or at integer times 0, 1, 2, 3, ..., is :
[tex]\displaystyle P(t)=P_0(1+r)^{t}[/tex]
Where Po is the value of P at time 0.
The country’s population in 1991 was 211 million, and in 1998 it was 215 million. We have two discrete times to define the equation and set the year 1991 as t=0. Thus, the year 1998 is t=7.
The preliminary equation is:
[tex]\displaystyle P(t)=211(1+r)^{t}[/tex]
To find the value of 1+r, we use the second point (7,215):
[tex]\displaystyle 215=211(1+r)^{7}[/tex]
Dividing by 211:
[tex]\displaystyle \frac{215}{211}=(1+r)^{7}[/tex]
Solving:
[tex]\displaystyle (1+r)=\sqrt[7]{\frac{215}{211}}[/tex]
Calculating:
[tex](1+r)=1.002686[/tex]
The complete equation is:
[tex]\displaystyle P(t)=211(1.002686)^{t}[/tex]
Estimate the population in 2012 (t=21):
[tex]\displaystyle P(21)=211(1.002686)^{21}[/tex]
[tex]P(21)\approx 223[/tex]
The population in 2012 is estimated in approximately 223 million people
15/20 + 12 /20 = 27/20 =
Answer:
1 7/20
Step-by-step explanation:
So, you added the 15/20 and 12/20 to get 27/20
Then to simplify 27/20 you have to see how many times 27 can go into 20
27 can go into 20 with a remainder of 7 which then will lead you to the answer of 1 7/20 and you can't simplify it anymore.
Hopefully, that helps.

Re(z)=
Im(z)=
Given a complex number z = a + b i, the real part is Re(z) = a and the imaginary part is Im(z) = b.
So given that z = 6 - 3 i, we have Re(z) = 6 and Im(z) = -3.

The mixed number 1 2/5 and the decimal number 1.4 can be used to represent the same value.
True or False
A statistics teacher gives a multiple-choice exam with 20 questions. The teacher wants to discourage guessing on the exam, so for each question the student earns 1 point for a correct answer, 0 points for no answer, and -1 point for a wrong answer. Consequently, if a student answered every question incorrectly the student would earn a score of -20 on the exam. However, if a student answered every question correctly, the student would earn a score of 20 on the exam. After the exam, the teacher distributes the list of test scores and asks the class to calculate the standard deviation. The first student to finish the calculations says that the standard deviation is -1.8.
a. True
b. False
Answer:
b. False
Step-by-step explanation:
The answer is false because the standard deviation was miscalculated.
We can compute the formula for calculating the standard deviation as:
[tex]\sigma = \sqrt{\dfrac{\sum (x_i-\overline x)^2}{n}}[/tex]
As a result of the square in the numerator of the summation, the square [tex]\sum (x_i-\overline x)^2[/tex] is usually non-negative.
Even if the data is positive, negative or zero, as a result of the above claim, the standard deviation is always non-negative.
Thus, the fact that the first student who finishes the calculation first and claim that the standard deviation is -1.8 is false.
