Answer: 55°
Step-by-step explanation: y and x are supplementary and equal 180°. Triangles also equal 180° so subtract the two angles you know and x is 125°. 180 - 125 = 55°
Answer:
y = 55°
Sum of the interior angles of a triangle = 180°
Therefore, x + 25°+30° = 180°
or, x + 55° = 180°
or, x = 180°-55°
or, x = 125°
Now, x + y = 180° ( straight angles)
125°+y = 180°
y= 55°
Given the diagram above, m∠Z is:
Answer:
120 deg
Step-by-step explanation:
The sum of the measures of the interior angles of a quadrilateral is 360 deg.
2t + 2t + t + t = 360
6t = 360
t = 60
m<Z = 2t = 2(60) = 120
Answer: 120 deg
1732.2097 has
significant figures.
Answer:
1732.2097 has 8 significant figures.
Step-by-step explanation:
Every non-zero digit is considered a significant number. Also, in some exceptional cases, zero can also be considered a significant figure if it is in the middle of two non-zero digits.
Just like in the number given, 1732.2097. We have 7 non-zero digits which certainly would be considered to be significant figures. Zero is between two significant figures, 2 and 9, therefore, it would also be referred to as a significant figure.
Therefore, the number, 1732.2097, has 8 significant figures.
ASAP What is the volume of a sphere, to the nearest cubic inch, if the radius equals 3 inches? Use π = 3.14. A. 101 in³ B. 210 in³ C. not given D. 96 in³
Answer: C. not given
Step-by-step explanation:
formula for volume of sphere: V=(4/3)πr³
V=(4/3)πr³
V=(4/3)(3.14)(3)³
V=(4/3)(3.14)(27)
V=113 in³
Answer:
C. Not given
V≈ 113 in³
Step-by-step explanation:
The volume of a sphere can be found using the following formula.
[tex]V= \frac{4}{3} \pi r^3[/tex]
We know the radius is 3 inches and we are using 3.14 for pi. Therefore, we can substitute [tex]3 in[/tex] in for [tex]r[/tex] and [tex]3.14[/tex] in for [tex]\pi[/tex]
[tex]V= \frac{4}{3} *3.14* (3 in)^3[/tex]
Evaluate the exponent first.
(3 in)³= 3 in * 3 in * 3 in = 9 in² * 3 in = 27 in³
[tex]V= \frac{4}{3} *3.14* 27 in^3[/tex]
Multiply 3.14 and 27 in³
[tex]V= \frac{4}{3} * 84.78 in^3[/tex]
Multiply 4/3 and 84.78 in³
[tex]V= 113.04 in^3[/tex]
Round to the nearest cubic inch. The 0 in the tenth place tells us to leave the 113 as is.
[tex]V= \approx 113 in^3[/tex]
Since 113 cubic inches is not an answer choice given, the correct answer is C. not given
In a different plan for area codes, the first digit could be any number from 2 through 5, the second digit was either 2, 3, 4, or 5, and the third digit could be any number except 4, 5, or 8. With this plan, how many different area codes are possible?
Answer:
Step-by-step explanation:
First digit 2,3,4,5 = 4 different digits.
Second digit 2,3,4,5 = 4 different digits.
Third digit = 1,2,3,6,7,9 = 6 different digits.
Total number of possibilities = 4*4*6 = 96
A proposed design for a habitable Mars colony is a hemispherical
biodome used to maintain a breathable atmosphere for the colonists.
Estimate the radius of the biodome if it is required to contain 5.5
billion cubic feet of air.
Answer:
r = 1.37 billion feet
Step-by-step explanation:
It is given that,
A proposed design for a habitable Mars colony is a hemispherical biodome used to maintain a breathable atmosphere for the colonists.
The volume of biodome is 5.5 billion cubic feet of air.
It is in the shape of a hemisphere. The volume of a hemisphere is given by :
[tex]V=\dfrac{2}{3}\pi r^3[/tex], r = radius
V = 5.5 billion cubic feet
[tex]r^3=\dfrac{3V}{2\pi}\\\\r^3=\dfrac{3\times 5.5}{2\times 3.14}\\\\r=(\dfrac{3\times 5.5}{2\times 3.14})^{1/3}\\\\r=1.37\ \text{billion feet}[/tex]
So, the radius of the biodome is 1.37 billion feet.
The radius of the biodome if it is required to contain 5.5 billion cubic feet of air is 1.38 billion feet and this can be determined by using the formula of the volume of the hemisphere.
Given :
A proposed design for a habitable Mars colony is a hemispherical biodome used to maintain a breathable atmosphere for the colonists.Volume of the biodome is 5.5 billion cubic feet.The following steps can be used in order to determine the radius of the biodome:
Step 1 - The formula of the volume of the hemisphere can be used in order to determine the radius of the biodome.
Step 2 - Formula of the volume of the hemisphere is given by:
[tex]\rm V =\dfrac{2}{3}\pi r^3[/tex]
where r is the radius of the hemisphere.
Step 3 - Now, substitute the value of V in the above formula in order to determine the value of 'r'.
[tex]\rm 5.5=\dfrac{2}{3}\pi r^3[/tex]
Step 4 - Simplify the above expression.
[tex]r^3=\dfrac{5.5\times 3}{2\pi}[/tex]
[tex]r = \sqrt[3]{\dfrac{16.5}{2\pi}}[/tex]
r = 1.38 billion feet

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The product of your age and the number of pets you have is 18.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that you are 9 years old, also, you have two pets. Therefore, the product of your age and the number of pets you have is,
Product = your age x Number of pets you have
= 9 x 2
= 18
Hence, the product of your age and the number of pets you have is 18.

151 degrees
Step-by-step explanation:
the angle alternate to 50 degrees is also 50 degrees
now, we have 2 angles inside our triangle, we can use the angle sum property to find the third one, which is forming a linear pair with the angle 'x'
so, 29 + x = 180 (linear pair)

a) Does the Range Rule of Thumb estimate more often underestimate or overestimate the actual standard deviation?
The Range Rule of Thumb is a simple method to estimate the standard deviation based on the range of a dataset.
It states that approximately 68% of the data lies within one standard deviation of the mean, and about 95% of the data falls within two standard deviations of the mean.
In terms of underestimating or overestimating the actual standard deviation, the Range Rule of Thumb tends to underestimate the true standard deviation. This is because the rule assumes a uniform distribution of data within each standard deviation, which is not always the case in real-world datasets. In reality, data distributions can be skewed or have outliers, which the Range Rule of Thumb does not consider.
As a result, relying solely on the Range Rule of Thumb for estimating the standard deviation may lead to inaccuracies, especially in datasets with non-uniform distributions or significant outliers. More robust methods, such as the sample variance and standard deviation formulas, are preferred for accurate estimation.

Answer:
[tex]\huge\boxed{Center = (3,3),Radius = 2\sqrt{15} }[/tex]
Step-by-step explanation:
Given equation is
[tex]x^2 + y^2 -6x-6y -42 = 0[/tex]
Adding 42 to both sides
[tex]x^2 + y^2 -6x-6y = 42\\[/tex]
Completing squares
[tex]x^2 -6x+y^2 -6x = 42\\(x)^2 - 2(x)(3) +y^2 - 2(y)(3) = 42[/tex]
Adding (3)² => 9 and (3)² => 9 to both sides
[tex](x-3)^2+(y-3)^2 = 42+9+9\\(x-3)^2 + (y-3)^2 = 60\\(x-3)^2 (y-3)^2 = (2{\sqrt{15})^2}[/tex]
Comparing it with [tex](x-h)^2+(y-k)^2 = r^2[/tex] where Center = (h,k) and Radius = r
We get:
Center = (3,3)
Radius = [tex]2\sqrt{15}[/tex]

Steven Kellogg, a machine operator, works at an hourly rate of $10.60 and
earns time and a half if he works any overtime. Given this, last week he
worked 37 hours plus 8 hours overtime. What is his straight-time pay? What
is his overtime pay? What is his total pay?
Answer:
[tex]Straight\ Time\ Pay = \$392.2[/tex]
[tex]Overtime\ Pay = \$42.4[/tex]
[tex]Total = \$434.6[/tex]
Step-by-step explanation:
Given
Hourly Rate = $10.60
Overtime = half hourly rate
Hours worked = 37 hours
Overtime = 8 hours
Calculating the Straight Time Pay
[tex]Straight\ Time\ Pay = Hourly\ Rate * Hours\ Worked[/tex]
[tex]Straight\ Time\ Pay = 37 * \$10.60[/tex]
[tex]Straight\ Time\ Pay = \$392.2[/tex]
Calculating the Overtime Pay
[tex]Overtime\ Pay = Overtime\ Rate * Overtime\ Hours[/tex]
Since, overtime rate is half of hourly rate; we have
[tex]Overtime\ Pay = \frac{\$10.6}{2} * 8[/tex]
[tex]Overtime\ Pay = \$5.3 * 8[/tex]
[tex]Overtime\ Pay = \$42.4[/tex]
Calculating Total Pay
This is calculated by adding results in (i) and (ii)
[tex]Total = Straight\ Time + Overtime[/tex]
[tex]Total = \$392.2 + \$42.4[/tex]
[tex]Total = \$434.6[/tex]
