Answer:
√200 or 14.1
Step-by-step explanation:
Pythagoras' Theorem: a²+b²=c²
Rearrange to get b² (one of the smaller sides): c²-a²=b²
225-25=200
√200 = 14.1
Answer:
14.1 I hope this helps! Brainliest please!
Step-by-step explanation:
So we use the Pythagorean theorem which is a squared + b squared = c squared. C is the hypotenuse. So we do:
15 squared - 5 sqaured = b squared
225 - 25 = b squared
200 = b squared
14.1 = b
What is the formula for the following arithmetic sequence?
-9, -2, 5, 12, ...
an = -9 + 7( n - 1)
an = -9 + (-7)( n - 1)
an = 7 + (-9)( n - 1)
an = 9 + (-7)( n - 1)
Step-by-step explanation:
an = -9 + 7(n-1)
because you start at -9 and go up by increments of 7
Fifteen disks with the given measurements are stacked on top of each other. Which expression does NOT give the volume of the cylinder that is formed?
Missing information:
[tex]r = 3cm[/tex]
[tex]h = 1cm[/tex]
Options:
(a) [tex]\pi * 3^2 * 15[/tex] (b) [tex]\pi * 3* 15^2[/tex]
(c) 15 times the volume of the disk
(d) The height of the stack multiplied by [tex]\pi r^2[/tex]
Answer:
(b) [tex]\pi * 3* 15^2[/tex]
Step-by-step explanation:
Given
15 identical disks
[tex]r = 3cm[/tex]
[tex]h = 1cm[/tex]
Required
Determine the odd option
The volume of 1 disk is:
[tex]V_1 = \pi r^2h[/tex]
[tex]V_1 = \pi * 3^2 * 1[/tex]
The volume of 15 is:
[tex]V_{15} = 15 * V_1[/tex]
[tex]V_{15} = 15 * \pi * 3^2 * 1[/tex]
[tex]V_{15} = \pi * 3^2 * 15[/tex]
The above equation represents (a), (c) and (d)
Because:
(a): [tex]V_{15} = \pi * 3^2 * 15[/tex]
(c) 15 * volume of the disk: [tex]V_{15} = 15 * V_1[/tex] = [tex]V_{15} = \pi * 3^2 * 15[/tex]
(d) height * [tex]\pi r^2[/tex] = h * [tex]\pi r^2[/tex] = [tex]15 * \pi * 3^2 * 1[/tex] = [tex]V_{15} = \pi * 3^2 * 15[/tex]
Hence, (b) is the odd option
The points L, M, N and O all lie on the same line segment, in that order, such that the ratio of LM:MN:NOLM:MN:NO is equal to 3:1:2.3:1:2. If LO=30,LO=30, find LN.LN.
Answer:
[tex]|LN| = 24[/tex]
Step-by-step explanation:
Given
[tex]LM:MN:NO = 3:1:2[/tex]
[tex]LO = 30[/tex]
Required
Find LN
[tex]LN = LM + MN[/tex]
From the ratio, LM = 3 and MN = 1
So:
[tex]LN = 3 + 1[/tex]
[tex]LN = 4[/tex]
LN and NO can be represented as:
[tex]LN : NO = 4 : 1[/tex]
The length of LN is then calculated as:
[tex]|LN| = \frac{LN}{LN+NO}*|LO|[/tex]
[tex]|LN| = \frac{4}{4+1}*30[/tex]
[tex]|LN| = \frac{4}{5}*30[/tex]
[tex]|LN| = \frac{4*30}{5}[/tex]
[tex]|LN| = \frac{120}{5}[/tex]
[tex]|LN| = 24[/tex]

Lines a and b are parallel. Parallel lines a and b are cut by transversals s and t. The angles formed by the intersection of lines a, s, and t, clockwise from top left are blank, blank, blank, blank, (7 x) degrees, blank; formed by lines b and s are blank, blank, blank, (11 x) degrees; formed by lines b and t are 90 degrees, blank, blank, blank. What is the value of x? 5 10 35 55
Answer:
x = 5
Step-by-step explanation:
Given that, exterior angles on the same side of a traversal are supplementary a Hence, sums up to 180°
Given the angles:
7x° + 11x° + 90° = 180°
18x° + 90° = 180°
18x° = 180° - 90°
18x° = 90°
x = 90° ÷ 18
x = 5

-x + 5y > -10
5y > x - 10
y = .2x - 2
Now, plug in any value of x to find y!
Ex: x = 5...
y = .2 (5) - 2
y = -1
Your first coordinate could be (5, -1)

in the product rule for exponents, what do you do to the coefficients? what do you do to the exponents?
Answer:
Do not multiply the coefficients and the exponents. Remember, using the Product Rule add the exponents when the bases are the same.
In the product rule of the exponents,
''For same base we can add the exponents of the coefficients.''
What is mean by expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Solve expression by using the product rule for exponents.
Now, We know that;
In the product rule for exponents;
When expression have same base then its exponents are add and the coefficients of expression are written as same as write in expression
Hence, In the product rule of the exponents,
''For same base we can add the exponents of the coefficients.''

Use the Proportionality Theorem to solve for X.
The proportion of 16 to 4 is 4 is 1/4 of 16( 4/16 = 1/4)
So x would be 1/4 of 12
12/4 = 3
X = 3
Answer:
Step-by-step explanation:
The proportion of 16 to 4 is 4 so 1/4 of 16( 4/16 = 1/4)
So x would be 1/4 of 12
12/4 = 3
X = 3

14. A right cone has a height of 14 in and a base diameter of 17 in.
a Sketch and label a diagram of the cone
b. Determine the area of the lateral surface of the cone, to the nearest square inch
Given:
The height of a right cone = 14 in
Base diameter = 17 in
To find:
The diagram of the cone and its lateral surface area.
Solution:
(a)
The diagram of a right cone with height 14 in and base diameter of 17 in is shown below.
Diagram is not to scale.
(b)
We know that lateral surface of the cone is
[tex]A=\pi rl[/tex]
[tex]A=\pi r\sqrt{r^2+h^2}[/tex] ...(i)
Where, r is the base radius, h is vertical height and l is the slant height of the cone.
Base radius of the cone = [tex]\dfrac{\text{Base diameter}}{2}[/tex]
[tex]r=\dfrac{17}{2}[/tex]
[tex]r=8.5[/tex]
Now,
Putting r=8.5, h=14 and π=3.14 in (i), we get
[tex]A=(3.14)(8.5)\sqrt{(8.5)^2+(14)^2}[/tex]
[tex]A=26.69\sqrt{72.25+196}[/tex]
[tex]A=26.69\sqrt{268.25}[/tex]
[tex]A=437.1379[/tex]
[tex]A\approx 437[/tex]
Therefore, the lateral surface area of the cone is 437 sq. inches.

Answer:
The answer is Step 2: m<w + m<z = 180 degrees (suppplmentary angles).
Step-by-step explanation:
First, Step 2 says m<w - m<z = 90 degrees. That's false because the m<w - m<z would equal an acute angle, not a right angle. Secondly, the m<w + m<z = 180 degrees. Supplementary angles equal 180 degrees.

Let the adjacent angles of the rhombus be 2x and 3x. We know that the sum of the measures of the adjacent angles is equal to 180°. AD = DC = 3 × 36° = 108°. Hence , the angles of the rhombus are 72° , 108° , 72° and 108°.
Step-by-step explanation:
Answer:
Let the adjacent angles of the rhombus be 2x and 3x.
we know that the sum of the measures of the adjacent angles is equal to 180°.
2x+3x=180
=5x=180
=x=180/5
=x=36°
Hence,AB =BC=2×36°=72°
AD=DC=3×36°=108°
Hence,The angles of the rhombus are 72°,108°, 72°and108°.

By what factor is the volume of the figure increased?
O4
O 8
O 32
O 64
Answer:
C. 32
Explanation:
The square-cube law states that "When an object undergoes a proportional increase in size, its new surface area is proportional to the square of the multiplier and its new volume is proportional to the cube of the multiplier." This means that if the surface area of the cube is increased by a certain amount, the volume of the cube will increase by the cube of that.
