A copper key is placed in a cylindrical container with a 3-cm diameter. The water level rises from 14 cm to 14.6 cm. What is the volume of the key?
Options:
The volume is about 4.24 cm^3.
The volume is about 3.72 cm^3.
The volume is about 2.96 cm^3.
The volume is about 1.41 cm^3.
Answer:
The volume is about 4.24 cm^3.
Step-by-step explanation:
From the question we are told that:
Diameter[tex]d= 3-cm[/tex]
Radius [tex]r=d/2=>1.5cm[/tex]
Height risen[tex]14.6-14=0.6cm[/tex]
Generally the equation for Volume of a Key is mathematically given by
Since Volume of a cylinder is Given as
[tex]V=\pir^2h[/tex]
Therefore
[tex]V=\pi*1.5^2*0.6[/tex]
[tex]V=4.2417\\\\V=4.24 cm^3[/tex]
Correct Option A
The volume is about 4.24 cm^3.

The value of x in the given isosceles triangle, is √55 units.
What is an isosceles triangle?A triangle with two sides equal is called an isosceles triangle.
Given that, an isosceles triangle, with base 6 units and legs 8 units, we need to find the length of the altitude x,
Since, ABC is an isosceles triangle, therefore, BD = DC = 6/2 = 3 units
Using the Pythagoras theorem,
AC² = DC² + AD²
8² = 3² + AD²
AD² = 64-9
AD² = 55
AD = √55
Hence, the value of x in the given isosceles triangle, is √55 units.

Find mAC.
Pls help me
Answer:
Measure of Arc AC is 30 degrees
Step-by-step explanation:
To find the value of the marked arc, we are going to use the arc-angle relationship
from the type of given diagram, we can figure out the relationship to use
Mathematically, we have this as;
Measure of Arc AC = 2 * angle ABC
So we have arc AC as 2 * 15
Arc AC = 30 degrees

What is the length of leg s of the triangle below?
45°
90°
45°
10v2
Answer:
B
Step-by-step explanation:
The 45 45 90 triangle means that the hypotenuse is just one of the two legs multiplied by rad2. This means that leg s is 10.
The length of the leg is 10.
Option B is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Sin 45 = Opposite face to angle 45/ Hypotenuse
1/√2 = s / 10√2
s = 10√2 / √2
s = 10
Thus,
The length of the leg is 10.

Give the value of x in each quadrilateral. Then state if the quadrilateral is a Trapezoid. Why/why not? (Hint: Shapes are not drawn
to scale)
Let's focus on the figure on the left.
For any quadrilateral, the angles always add up to 360. We'll use this to find x.
105+80+75+x = 360
260+x = 360
x = 360-260
x = 100
Now notice that the pair of adjacent angles 105 and 80 add up to 105+80 = 185, which is not 180. Similarly, the adjacent angles 80 and 75 add to 155 which is not 180.
This is enough to show that we don't have any parallel lines here. If we did have parallel lines, then adjacent angles would add to 180.
Since none of the lines are parallel, this figure is not a trapezoid
Any trapezoid has exactly one pair of parallel lines.
-------------------------------------------------------------------------------------
Move onto the figure on the right
We'll follow the same ideas mentioned in the last section.
x+110+92+88 = 360
x+290 = 360
x = 360-290
x = 70
Note how the adjacent angles 70 and 110 add to 70+110 = 180. This shows they are supplementary angles and that we do have a set of parallel lines (top and bottom). In contrast, the angles 110 and 92 do not add to 180, so that helps us see we only have one pair of parallel lines.
Therefore, the figure is a trapezoid

3x+1 is your simplified answer, since it is an expression it cannot be simplified any further.
Triangle A is reflected in the x axis to give triangle B, which is then reflected in the line y=x to give Triangle C. Draw Triangle C.
Step-by-step explanation:
always draw triangle b first. for triangle b it is reflected across the x-axis which means all y valies become negative. then for triangle c, you swap the x and y values around.

what is the zero of the function
Answer:
A
Step-by-step explanation:
The zero is the value of x where the line crosses the x- axis
The line crosses the x- axis at x = - 5 ← zero
Answer:
-5
Step-by-step explanation:
The zero of a function is the x-value of the location where the function intersects the x-axis.
Here I read at (-5,0), the function intersects the x-axis, so the zero of the functiion is x = -5

[tex]\sf{\implies 10\% \ of \ N = 25}[/tex]
[tex]\sf{\implies \dfrac{10}{100} \times N = 25}[/tex]
[tex]\sf{\implies \dfrac{N}{10} = 25}[/tex]
[tex]\sf{\implies N = 250}[/tex]
Now we need to find 60% of 250

Jenna has 10 3/4 yards of fabric. She uses 6 2/3 yards to make a banner.
How much fabric is left?
Enter your answer in the box as a mixed number in simplest form and in Yards.
Answer:
4 1/12 yards of fabric left.
Step-by-step explanation:
First things first: convert the mixed numbers so they have the same denominator
The least common multiple of 4 and 3 is 12, so the common denominator will be 12.
So Jenna has 10 9/12, and uses 6 8/12.
Now subtract:
10 9/12 - 6 8/12 = 4 1/12
So there is 4 1/12 yards of fabric left.
