Answer:
1st ∡ = 15.5°
2nd ∡ = 77.25°
3rd ∡ = 87.25°
Step-by-step explanation:
1st ∡: x
2nd ∡: y
3rd ∡: z
Equations we can create from data given in problem:
y + z = 5x
z = 5x + 10
We have enough expressions to create an equation:
x + 5x + 5x + 10 = 180
11x = 170
x = 15.5
y = 5(15.5) = 77.25
z = y + 10 = 87.25

Bill buys a large can of paint. The size of the can is measured in which unit?
Answer:
Barometer i think im not sure
Step-by-step explanation:
Pressure is a mechanical (non-electrical and non-magnetic) measure. All mechanical measures can be derived from just three basic mechanical units. Which three we use is actually arbitrary. This means that using three we can produce or define all other mechanical measures by multiplying or dividing some combination of the chosen three.
Most measuring systems use time, length, and mass as the basic three in which case pressure would be mass / (time * time * length * length). Compare that with kilogram per (meter*meter * second*second) which is also called a Pascal.
Another measuring system might use time, length, and force as the three basic measures. Here mass is omitted in place of force. Nothing is lost because mass and force can be written in terms of the other with the help of time and length. In this case pressure would be force / (length*length). Compare this with Newton per meter*meter which also defines a Pascal.
How pressure is measured in practice is another good question. The standard method is to use some device that employs a medium to compare the unknown pressure to some known familiar pressure. Mercury tubes illustrate this nicely and are still used in laboratories. They work because mercury is a very dense fluid. A lighter fluid can push upon and move a column of mercury but cannot pass through it.
Measuring the movement of mercury when a known pressure is applied to one end reveals the pressure at the other end. The persistence of millimeters of mercury (mmHg) as a unit for reporting pressure is testament to this method. Other pressure gages work by employing something like springs or strain sensors calibrated to mimic the readings that a mercury tube would report.

PLEASE HELP! SO Confused
You and your friend got tricked into helping another friend move stuff from a garage into moving truck. The ramp used is 12 feet long and makes a 36° angle with the horizontal ground. You discover that the incline is just too steep, so you replace the ramp with one that is 32 feet long. What angle does this replacement ramp make with the ground? Round your answer to the nearest tenth of a degree.
Answer:
12.73 Degrees
Step-by-step explanation:
I'm going to assume some things. The height of the truck is not changing, i.e. the distance and length of the ramp are but the height stays the same.
We draw our right triangle, see photo*
We really only care about finding out what side a is so
[tex]c = \frac{a}{sin(A)} \\12 = \frac{a}{sin(36)} \\12sin(36) = a\\a = 7.05342302750\\sin(x) = (\frac{opp}{hyp} )\\sin(x) = (\frac{7.05342302750}{12} )\\= 35.9999 \:degrees[/tex]
So, since I stated that height did not change, the same process just using 32 for the hypotenuse.
[tex]sin(x) = (\frac{opp}{hyp} )\\sin(x) = (\frac{7.05342302750}{32} )\\= 12.73367164 \:degrees[/tex]
How many 1/9's in 31
There are a total of 279 1/9s in 31.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
To find out how many 1/9's are in 31, you can divide 31 by 1/9.
This can be simplified by converting the division of a fraction to multiplication with its reciprocal:
31 ÷ (1/9) = 31 × (9/1)
Simplifying the expression on the right side gives:
31 × 9 = 279
So there are 279, 1/9's in 31.

Use the following information to find the test statistic of the sample used to test the claim that daily rainfall amounts in the northeastern United States are less than 0.13 inches.
n = 45, x = 0.10 in., s = 0.26 in.
t = –8.263
t = –0.774
t = –2.580
t = –0.395
Using the t-distribution, the test statistic is given as follows: t = -0.774.
What is the test statistic of a t-distribution test hypothesis?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

(c) The line with equation y = 2x +k is a tangent to curve y = 3x² +4. Find the value of k.
Answer:
k = 11/3
Step-by-step explanation:
If the line is tangent to the curve, then Δ = 0.
______________
Remembering:
Δ>0 two different points of intersection x' [tex]\neq[/tex]x''
Δ=0 one point of intersection x' = x''
Δ<0 two different points of intersection in the complex plan x' and -x'
______________
As the line and the curve have one point of intersection, which is (x, y), we can make a equality between them:
2x + k = 3x² + 4
0 = 3x² - 2x + (4 - k)
Now we can use the Δ=0 (Δ= b² - 4ac)
Δ = 0 = (-2)² - 4.3.(4-k)
0 = 4 - 48 + 12k
12k = 44
k = 44/12 = 2 . 22 /3. 2.2 = 22/3.2 = 11/3
k = 11/3

Answer: The guy that answered this question is right
If Wyatt initially invests an amount of $1200 for 4 years at a simple interest of 6.2% and then the amount from that is invested for 5 years at a simple interest of 8%, the new account balance at the end is 2096.64 dollars.
Therefore the answer is $2096.64
What is simple interest?The amount when invested an initial amount of P for n years at annual simple interest rate of r is given by
A = P + Pnr
here, we have,
As Wyatt invest an amount of $1200 at 6.2% simple interest, at the end of 4 years he will have an amount equal to
A = 1200 + 1200×4×0.062
A = 1497.6
Now as Wyatt invest an amount of $1497.6 at 8% simple interest, at the end of 5 years he will have an amount equal to
A = 1497.6 + 1497.6×5×0.08
A = 2096.64

what is 36 divided by 6 equals blank sold 36000 divided by 6 equals
Step-by-step explanation:
The correct calculations show that 36 divided by 6 equals 6, and 36000 divided by 6 equals 6000.
When we divide 36 by 6, the quotient is 6. Therefore, 36 divided by 6 equals 6.
Similarly, when we divide 36000 by 6, the quotient is 6000. Therefore, 36000 divided by 6 equals 6000.
To calculate these divisions, we divide the dividend (36 and 36000) by the divisor (6) to find the quotient.
In the case of 36 divided by 6, we have 36 ÷ 6 = 6.
For 36000 divided by 6, we have 36000 ÷ 6 = 6000.
Hence, the correct calculations show that 36 divided by 6 equals 6, and 36000 divided by 6 equals 6000.
