if m1=35° and m2=75°, what is m3?
Answer:
m3 should be 70°
all internal angles of a triangle add up to 180
180-35-75 = 70
Answer:
All angles of a triangle add up to 180°.
there m1+m2+m3=180°
35+75+m3=180
110°+m3=180°
m3=180°-110°
m3=70°

Light travels at approximately 186,000 miles per second. How is 186,000 written in scientific notation?
Answer:1.86*10^5
Step-by-step explanation:
Scientific notation is simple. First you place a decimal after the first numerical digit. Then for every digit after the decimal you would multiply by 10 to get back to the standard form. Instead of constantly multiplying by 10 you will raise the exponent.

Choose 1 answer:

Outliers are data elements that are relatively far from the other data elements.
There are 2 high outliers in the data set.
The five number summary is given as:
[tex]\mathbf{Minimum=3}[/tex]
[tex]\mathbf{Q_1=6}[/tex]
[tex]\mathbf{Median=12}[/tex]
[tex]\mathbf{Q_3=13}[/tex]
[tex]\mathbf{Maximum=39}[/tex]
The lower outlier is:
[tex]\mathbf{L = Q_1 - 1.5 \times (Q_3 - Q_1)}[/tex]
So, we have:
[tex]\mathbf{L = 6- 1.5 \times (13 - 6)}[/tex]
[tex]\mathbf{L = -4.5}[/tex]
The upper outlier is:
[tex]\mathbf{U = Q_3 + 1.5 \times (Q_3 - Q_1)}[/tex]
So, we have:
[tex]\mathbf{U = 13 + 1.5 \times (13 - 6)}[/tex]
[tex]\mathbf{U = 23.5}[/tex]
The above computation means that;
Data less than -4.5 or greater than 23.5 are outliers
The data elements in this range are: 26 and 39
Hence, there are 2 high outliers in the dataset

What is the surface area of a cereal box with a height of 10 inches, a width of 4 ½ inches, and a length of 7 inches?
Answer:
Surface area of a box = 293 inches ²
Step-by-step explanation:
Surface area of a box = 2(lw + lh + hw)
Where,
l = length = 7 inches
w =width = 4 1/2 inches
h = height = 10 inches
Surface area of a box = 2(lw + lh + hw)
= 2(7*4.5 + 7*10 + 10*4.5)
= 2(31.5 + 70 + 45)
= 2(146.5)
= 293 inches ²
Surface area of a box = 293 inches ²

The zeroes of the quadratic function given are 5/2 + √31 / 2 and 5/2 - √31 / 2.
What are Quadratic Functions?Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.
The general form of a quadratic function is f(x) = ax² + b x + c.
Given quadratic function is
f(x) = 2x² - 10x - 3
We can find the roots of the quadratic function using the quadratic formula.
Quadratic formula for the quadratic function f(x) = ax² + b x + c is,
x = [-b ± [tex]\sqrt{b^2-4ac}[/tex]] / 2a
Here, a = 2, b = -10 and c = -3
Substituting the values,
x = [-(-10) ± [tex]\sqrt{(-10)^2-(4*2*-3)}[/tex]] / (2 × 2)
= (10 ± √(100 + 24) ) / 4
= (10 ± √124) / 4
= (10 ± √(31 × 4)) / 4
= (10 ± √31 √4) / 4
= (10 ± 2√31) / 4
= 10/4 ± 2√31 / 4
= 5/2 ± √31 / 2
Hence the roots are 5/2 + √31 / 2 and 5/2 - √31 / 2.

The measure of angle P is ___ degrees, rounded to the nearest hundredth.
Answer:
53°
Step-by-step explanation:
Use sine cosine or tangent (SOHCAHTOA). For this example I'll use sine.
For sine you'd use the equation sin(x)=[tex]\frac{opp}{hyp}[/tex] where x is the missing angle measure
the opposite side from x is 45 cm and the hypotenuse is 53 cm
sin(x)=[tex]\frac{45}{53}[/tex]
then rearrange the equation like this x=[tex]sin^{-1}[/tex]([tex]\frac{45}{53}[/tex])
most graphing calculators should solve it from there if you plug it in, hope this helps! :)
A marathon takes place each year.In 2020 there were 6500 runners.Does this predict that in 2023 there will be more than 7500 runners? { Prediction : For each of the next 3 years the number of runners will increase by 5% } Does this predict that in 2023 there will be more than 7500 runners?
Answer:
yes
there would be 7525 runners
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r) n
FV = Future value
P = Present value
R = interest rate
N = number of years
6500 x (1.05)^3 = 7525 runners
