<1 and <2 are complementary angles.the measure of <1 is 10
the Measure of <2 is 4c
Answer:
c = 20
Step-by-step explanation:
You have not really asked a question.
I will assume you are asking about the value of c.
The measure of angle 1 is 10 (assuming degrees!), so the measure of angle 2 is 80. (Complementary angles have measures that sum to 90.)
The measure of angle 2 is also described as 4c, so 4c = 80. That makes c = 20.
Which of these lengths CANNOT represent the sides of a triangle? {28, 30, 58} {32, 34, 60} {13, 20, 27} {2, 4, 5}
Answer:
[tex]A.\ {28, 30, 58}[/tex]
Step-by-step explanation:
Required
Which of the lengths do not form a triangle
To do this, we make use of triangle inequality theorem which states that.
[tex]a + b > c[/tex]
[tex]b + c > a[/tex]
[tex]a + c > b[/tex]
Where [tex]a,\ b\ and\ c[/tex] are the sides of the triangle.
So, we have:
[tex]A.\ {28, 30, 58}[/tex]
[tex]28 + 30 > 58[/tex] --- False
[tex]58 + 30 > 28[/tex] --- True
[tex]28 + 58 > 30[/tex] --- True
[tex]B.\ {32, 34, 60}[/tex]
[tex]32 + 34 > 60[/tex] -- True
[tex]32 + 60 > 34[/tex] -- True
[tex]34 + 60 > 32[/tex] -- True
[tex]C.\ {13, 20, 27}[/tex]
[tex]13 + 20 > 27[/tex] -- True
[tex]13 + 27 > 20[/tex] -- True
[tex]20 + 27 > 13[/tex] --- True
[tex]D.\ {2, 4, 5}[/tex]
[tex]2 + 4 > 5[/tex] --- True
[tex]2 + 5 > 4[/tex] -- True
[tex]5 + 4 > 2[/tex] --- True
From the computations above, only (A) cannot form a triangle

Rian is packing toys in boxes. Each box is 3 inches by 4 inches by 6 inches. Each toy takes up 65% of the volume of the box, and the rest of the volume of the box is filled with foam packing beads. What is the volume, in cubic inches, of the foam packing beads used to fill each box
9514 1404 393
Answer:
25.2 in³
Step-by-step explanation:
The volume of the box is ...
V = LWH
V = (3 in)(4 in)(6 in) = 72 in³
__
65% of the box is filled with a toy, so the remaining 100% -65% = 35% is filled with packing beads. The volume of packing beads required is ...
0.35 × 72 in³ = 25.2 in³
25.2 in³ of foam packing beads are used to fill each box.

Answer:
[tex]525\pi[/tex]
Step-by-step explanation:
Volume of a cylinder is given by the function [tex]v=\pi r^{2}h[/tex]
where v is volume, r is radius and h is height.
In order to find the radius we just divide the diameter in half and get
[tex]\frac{10}{2} =5=r[/tex]
now we just plug the values in the formula
[tex]v=\pi r^{2}h\\=\pi (5^{2})(21)\\=\pi (25)(21)\\=525\pi[/tex]
Answer:
Volume of a cylinder: V = π (r^2) h
Step-by-step explanation:
First, find your radius and your height.
H = 21
D = 10
R = 1/2 d = 5
Then plug them into the equation: V = π (r^2) h
V = π (5^2) 21
V = π (25) 21
V = π (25 x 21)
V = π (525)
V = 525π

The boiling temperature (in degrees Celsius) of platinum is 199 more than four times the boiling temperature $z$ (in degrees Celsius) of zinc.
a. Write an expression that represents the boiling temperature (in degrees Celsius) of platinum.
b. The boiling temperature of zinc is 907 degrees Celsius. What is the boiling temperature of platinum?
Answer: THIS IS SO HARD!
Step-by-step explanation:
The required boiling temperature of platinum is 3,739 degrees Celsius.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Here,
a. Let's start by defining a variable for the boiling temperature of zinc, which we'll call z.
According to the problem statement, the boiling temperature of platinum is 199 more than four times the boiling temperature of zinc. In other words,
Boiling temperature of platinum = 4z + 199
So the expression that represents the boiling temperature of platinum in degrees Celsius is:
4z+199
b. The problem tells us that the boiling temperature of zinc is 907 degrees Celsius. So we can substitute this value for z in our expression:
4z+199 = 4(907)+199 = 3,739
Therefore, the boiling temperature of platinum is 3,739 degrees Celsius.

There are 320 students in a school. 16 come to school by car. 96 walk to school. Estimate the probability that a particular student: a arrives by car b walks to school c does not walk to school d does not walk or come by car.
Answer:
a. The probability that a particular student arrives by car is [tex]\frac{1}{20}[/tex] = 0.05, which equals 5%.
b. The probability that a particular student walks to school is [tex]\frac{3}{10}[/tex] = 0.3, which equals 30%.
c. The probability that a particular student does not walk to school is [tex]\frac{7}{10}[/tex] = 0.7, which equals 70%.
d. The probability that a particular student does not walk or come by car is [tex]\frac{13}{20}[/tex] = 0.65, which equals 65%.
Step-by-step explanation:
Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]
In this case, the number of possible cases is always the same, which is equal to the total number of students. So the number of possible cases is 320 students. The number of favorable cases varies as follows:
a. Number of favorable cases= number of students that arrive by car= 16
So: [tex]P(A)=\frac{16}{320}[/tex]
P(A)=[tex]\frac{1}{20}[/tex] = 0.05, which equals 5%
The probability that a particular student arrives by car is [tex]\frac{1}{20}[/tex] = 0.05, which equals 5%.
b. Number of favorable cases= number of students that walk to school= 96
So: [tex]P(A)=\frac{96}{320}[/tex]
P(A)=[tex]\frac{3}{10}[/tex] = 0.3, which equals 30%
The probability that a particular student walks to school is [tex]\frac{3}{10}[/tex] = 0.3, which equals 30%.
c. Number of favorable cases= number of students that do not walk to school = 320 students - number of students that walk to school= 320 students - 96 students= 224 students
So: [tex]P(A)=\frac{224}{320}[/tex]
P(A)=[tex]\frac{7}{10}[/tex] = 0.7, which equals 70%
The probability that a particular student does not walk to school is [tex]\frac{7}{10}[/tex] = 0.7, which equals 70%.
d. Number of favorable cases= number of students that do not walk or come by car= 320 students - number of students that walk to school - number of students that arrive by car= 320 students - 96 students - 16 students= 208 students
So: [tex]P(A)=\frac{208}{320}[/tex]
P(A)=[tex]\frac{13}{20}[/tex] = 0.65, which equals 65%
The probability that a particular student does not walk or come by car is [tex]\frac{13}{20}[/tex] = 0.65, which equals 65%.

C On exactly 25% of these days, Shane drank 3 to 4 glasses of water.
Don exactly 60% of these days, Shane drank 5 to 6 glasses of water
The histogram representing the data is attcwhwd in the picture below.
Answer:
C On exactly 25% of these days, Shane drank 3 to 4 glasses of water.
Step-by-step explanation:
The number of 8 - ounce glasses is represented on the x - axis and the number of days on the y - axis.
From the histogram ;
Shane drank 1 - 2 glasses on exactly 1 day
Shane drank 3 - 4 glasses on exactly 3 days
Shane drank 5 - 6 glasses on exactly 6 day
Total number of days = 12
60% of 12 = 7.2
On exactly 60% of the days, which is 7.2 days, number of glasses drunk isn't covered by the histogram
25% of 12 ; 0.25 * 12 = 3 days
From the histogram, number of glasses consumed is 3 - 4 glasses ; which is the only true statement about the histogram in the options given.
JL is a common tangent to circles M and K at point J. If angle MLK measures
619, what is the length of radius MJ? Round to the nearest hundredth. (Hint:
Show that triangles LMJ and LKJ are right triangles, and then use right triangle
trigonometry to solving for missing sides of the right triangles.) (10 points)
pls help
Answer:
MJ = 6.5
Step-by-step explanation:
Tangent lines to a circle are perpendicular to the radius.
tan 68° = JL/3
2.4751 = JL/3
JL = 7.4253
∠JLK = 90° - 68° = 22°
∠MLJ = 61° - 22° = 39°
sin 61° = MJ/7.4253
MJ = 7.4253(0.8746) = 6.5
The length of radius MJ is 5.99 units
How to calculate the radius MJ?Start by calculating the length JL using the following tangent ratio
tan(68°) = JL/3
Make JL the subject
JL = 3 * tan(68°)
Evaluate the product
JL = 7.4
From the figure, the measure of angle MLJ is:
∠MLJ = MLK - JLK
Where:
∠JLK = 90° - 68° = 22°
So, we have:
∠MLJ = 61 - 22
∠MLJ = 39
The radius MJ is then calculated using the following tangent ratio
tan(39) = MJ/JL
This gives
tan(39) = MJ/7.4
Make MJ the subject
MJ = 7.4 * tan(39)
Evaluate
MJ = 5.99
Hence, the length of radius MJ is 5.99 units
