The diagram shows triangle ABC. Angel ABC is NOT an obtuse angle. Find the greatest value of x. You must show all your working. (Your final line should say ‘Greatest value of x is..’)
First, an angle in a triangle is always less than 180.
An obtuse angle is defined to be greater than a right angle, but less than 180. Since angle ABC is not an obtuse angle, its measurement must be 90 degrees or less.
Angle ABC = x + 3x + 30 = 4x + 30
Since we want x to has its greatest value, angle ABC must also have its greatest value ( -> 90)
Now, we find x : (90-30)/4 = 15
So, the greatest value of x is 15. (recheck : 15 + 15 x 3 + 30 = 90)
Given the set of data below. 1 /2 , 1 /2 , 3 /2 , 3 /2
Estimate the measure of angle 1
Answer:
The answer is 140 degrees.
Step-by-step explanation:
It is closer to 90 degrees than 180 degrees, but it is greater than 90 degrees and bigger than 180 degrees.
Hope this helps.

10. A company is designing a new cylindrical water bottle. The volume
of the bottle is 103 cubic centimeters. What is the radius of the
water bottle? Estimate using 3.14 for , and round to the nearest
hundredth.
The radius of the water bottle to the nearest hundredth is 2.01 cm
How to calculate the volume of a cylinderA cylinder is a solid figure with circular bases and height.
The volume of a cylinder = πr²h
h is the height = 8.1cm
Volume = 103 cubic cm
Substitute into the formula to have
V = 3.14r² * 8.1
103 = 3.144 * 8.1 * r²
r = 2.01 cm
Hence the radius of the water bottle to the nearest hundredth is 2.01 cm

1. The volume of a cylinder is 461.58 cubic inches. If the cylinder has a height of 3 units, what is the radius of the cylinder? Use 3.14 for pi.
2. Find the volume of the cone that has a height of 12 and diameter of 12. Use 3.14 for pi. Round your answer to the nearest tenths place.
3. Find the volume of the hemisphere that has a radius of 7 inches. Use 3.14 for pi. Round your answer to the nearest hundredth.
4. The volume of a sphere is 407.51 cubic units. What is the diameter of the sphere?
The radius of the cylinder is 7 in, the volume of the cone is 452.2 unit³, the volume of the hemisphere is 1436 in³ while the diameter of the sphere is 14.6 units
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
a) Volume of cylinder = π * radius² * height
461.58 = 3.14 * radius² * 3
radius = 7 in
b) Volume of cone = (1/3) * π * radius² * height
Volume = (1/3) * 3.14 * (12/2)² * 12
Volume = 452.2 unit³
c) Volume of sphere = (4/3) π * radius³
Volume of sphere = (4/3) * 3.14 * 7³
Volume = 1436 in³
d) Volume of sphere = (4/3) π * radius³
407.51 = (4/3) * 3.14 * radius³
Radius = 7.3
Diameter = 14.6 units

Given p(x) = -4(x-15)[tex]p(x) = -4(x-15)x^{2} +2.[/tex]
Do number 10 please
To solve this problem, let's first understand the information given
⇒ says that 150% of expected people showed up
⇒ the number of expected people is 340
⇒ means 150% of 340 is the number of people who showed up
⇒ written mathematically 150% is equivalent to 150/100.
To find the exact number of people we must time 150/100 to 340
[tex]\frac{150}{100}*340=1.5 * 340 = 510[/tex]
That means 510 people showed up

The side lengths of three triangles are shown in the table. Which of the triangles is a right triangle? Select all that apply. Triangle Side Lengths | 610 810 1 || 7 7 13 ||| 313 413 513 A. Triangle I B. Triangle II C. Triangle III D. None of the above E. All of the above
To identify whether or not a triangle is a right triangle, it must satisfy the pythagorean theorem : [tex]a^{2}+ b^{2} =c^{2}[/tex] (where a;b;c represent the 3 sides, and c being the hypotenuse)
Replace the lengths :
Triangle 1 : [tex]1^{2} + 610^{2} \neq 810^{2}[/tex] (not right triangle, also does not satisfy the triangle inequality, so not a real triangle)
Triangle 2 : [tex]7^{2} + 7^{2} \neq 13^{2}[/tex] (not right triangle)
Triangle 3 : [tex]313^{2} + 413^{2} \neq 513^{2}[/tex] (not right triangle)
So, correct answer is D

An experiment consists of rolling a die and then flipping a coin.
The following tree diagram shows the possible outcomes.
A tree diagram in which a center point branches to numbers 1 through 6, which each branch to an H & T.
What is the probability of rolling an even number or flipping a tail?
Enter your answer as a reduced fraction, like this: 3/14
Using it's concept, it is found that the probability of rolling an even number or flipping a tail is of [tex]\frac{3}{4}[/tex].
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, there are 12 outcomes. Of those, 3 result in an even number and a tail, 3 more in an even number but not tail and 3 in a tail but an odd number, hence there are 9 desired outcomes.
Hence, the probability is given by:

Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between angles and sides and trig functions in a right triangle. Here, the side adjacent and the side opposite the marked angle are also marked. That means the relevant trig relation is ...
Tan = Opposite/Adjacent
tan(49°) = x/(22.2 m)
Multiplying by the denominator, we get ...
x = (22.2 m)tan(49°) ≈ 25.5 m
The unknown side is about 25.5 meters.
