Answer:
YES
Step-by-step explanation:
True or false: If you apply a scale factor of 3 to the sides of a rectangle, then the area is 3 times larger.
Answer:
False, the area will be 9 times larger
Step-by-step explanation:
You are adding 3 to each dimension, and that extra 3 becomes 3 x 3 when finding area
Rohan draws a circle of radius 10 cm with the help of compass and scale. He also draws two chords, AB and CD in such a way that AB and CD are 6 cm and 8 cm from the centre O. Now, he has some doubts that are given below. Help him out by answering these questions:
a)what will be the chord of ab?
b)what wil be the chord of cd?
Answer:
a) 16 cmb) 12 cmStep-by-step explanation:
Connect the center with A and C:
OA = 10 cm or OC = 10 cmUse Pythagorean to find half of AB:
[tex]AB/2=\sqrt{10^2-6^2} =\sqrt{64} =8[/tex][tex]AB = 16[/tex]Similarly, find the length of CD:
[tex]CD/2=\sqrt{10^2-8^2} =\sqrt{36} =6[/tex][tex]CD=12[/tex]
Length of AB = 16 cm
h² = p² + b²
10² = 6² + b²
100 = 36 + b²
[tex]b = \sqrt{64} [/tex]
[tex]= 8 cm[/tex]
[tex]AB = 8 + 8[/tex]
[tex]= 16 cm[/tex]
What is the measure of angle y in this figure?
Enter your answer in the box.
y=__
Answer:
163°
Step-by-step explanation:
Since those 2 arrows are straight lines that go through each other, angles that are opposite are the same. So the opposite of y is 163°.
can someone please teach me how to do percentage
Answer:
value/total value • 100 = percentage
Step-by-step explanation:
if 5 out 100 kids have red backpacks then 5% of kids have red backpacks
5/100 • 100 = percentage
0.05 • 100 = percentage
5% = percentage
if 13 cars out of 41 have flat tires, then 32% of the cars have flat tires
13/41 • 100 = percentage
0.31707317073... • 100 = 31.707317073... %
depending on your precision, you may include as many decimal places as you like, unless the question specifies it. For our example, we will round to 2 decimal places.
31.707317073... % = 31.71%
if you're looking to find percentages for probability, you will use the same equation.
the odds of flipping a coin and it landing on heads are 50%
possibilities:
Heads, Tails
there is one outcome where our result occurs out of the two possible outcomes
1/2 • 100 = percentage
0.5 • 100 = percentage
50% = percentage
Hope this helps and wasn't confusing

Answer:
Ans is D
Step-by-step explanation:
The points N(-4,3)(−4,3), O(-4,-3)(−4,−3), and P(5,3)(5,3) form a triangle. Plot the points then click the "Graph Triangle" button. Then find the perimeter of the triangle. Round your answer to the nearest tenth if necessary.
The perimeter of the triangle = 25.8 units.
What is the Perimeter of a Triangle?Perimeter = the sum of the length of all three sides
Given:
N(-4,3)
O(-4,-3)
P(5,3)
Perimeter of triangle NOP = NO + OP + NP
Find NO:
NO = |3 - (-3)| = 6 units
Find NP:
NP = |-4 - 5| = 9 units
Using the distance formula, find OP:
OP = 10.8 units
Therefore, Perimeter of the triangle = 10.8 + 9 + 6 = 25.8 units.

5. What is the distance from V to W? V=8 cm W 15 cm m<VW= 90
Answer:
17 cm
Step-by-step explanation:
If the angle between V and W is 90°, then this implies that V and W are legs of a right triangle (and the distance between them is the hypotenuse).
Use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse of a right triangle.
Let D = distance between V and W:
⇒ V² + W² = D²
⇒ 8² + 15² = D²
⇒ 289 = D²
⇒ D = √289
⇒ D = 17
Therefore, the distance from V to W is 17 cm
[tex]\huge \boxed{\sf 17\ cm}[/tex]
Pythagoras discovered that the square of the hypotenuse of a right-angled triangle, where one of the angles is 90 degrees, equals the sum of the squares of the other two sides.
[tex]\sf a^2 + b^2=c^2\\\\8^2 + 15^2=c^2\\\\ \sqrt{8^2 + 15^2} =c\\\\17=c[/tex]
What is the average distance from the mean, using this data? 10, 8, 5, 12, 20
Hey there!
• When you hear the word “mean” in mathematics it usually defined as “average”.
• To find it you have to ADD all of the numbers DIVIDE all of the numbers you have in the given data plot.
YOUR EQUATION:
10 + 8 + 5 + 12 + 20 / 5
= 18 + 5 + 12 + 20 / 5
= 23 + 12 + 20 / 5
= 35 + 20 / 5
= 55 / 5
= 11
Therefore, your answer is: 11

Ms. Bales wants to purchase tickets to see Adele in Nashville for $50 from a company that charges a one time fee of $4.75 for using the service. She is on a budget, so her purchase cannot exceed $200. Enter an inequality to determine the number of tickets, t, Ms. Bales can purchase
Answer:
50x + 4.75 ≤ 200
Step-by-step explanation:
Let x = number of Adele tickets
Cost of 1 Adele ticket = $50
One-time service fee = $4.75
Therefore, 50x + 4.75 ≤ 200

Answer:
[tex]y = \frac{4}{3}x + 2[/tex]
Step-by-step explanation:
Find the equation for the line in slope-intercept form: [tex]y = mx + b[/tex]
where m is the slope (gradient) and b is the y-intercept.
To find the slope (m)
Choose 2 points on the line: (0, 2) and (6, 10)
Let (0, 2) = [tex](x_1,y_1)[/tex]
Let (6, 10) = [tex](x_2,y_2)[/tex]
Use the slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{10-2}{6-0} =\frac{4}{3}[/tex]
Therefore, [tex]y = \frac{4}{3}x + b[/tex]
To find the y-intercept
The y-intercept is when x = 0 (where the line intersects the x-axis).
By inspection, the line intersects the y-axis at y = 2.
Therefore, y-intercept = 2
So, [tex]y = \frac{4}{3}x + 2[/tex]

you know how to multiply two expressions ?
every term of every expression is multiplied with every term of the other expression and the results are added (while considering any specific signs, if course).
(2x² + 3)(2x² - 3) = 2x²×2x² + -3×2x² + 3×2x² + 3×-3 =
4x² - 6x² + 6x² - 9 = 4x² - 9
and that is exactly the right side of the original equation.
so, it is correct.

Calculate the difference between the 10th term and 50th term of the sequence 9,14,19,24, ... ...
Answer:
Step-by-step explanation:
Number series : 9, 14, 19, 24
First term = a1 = 9
common difference = a2 - a1 = 14 - 9=5
Find the nth term:
an = a1 + + (n - 1)d
an = 9+ (n - 1)(5)
an = 9+5n - 5
an = 4 + 5n
Find the 10th term:
an = 4 + 5n
a10 = 4 + 5(10)
a10 = 4 + 50
a10 = 54
Find the 50th term:
an = 4 + 5n
a50 = 4 + 5(50)
a50 = 254
Find the difference between the 10th and
50th term:
Difference = 254 - 54 = 200
Answer: The difference is 200
Given the data from the question, the difference between the 10th term and the 50th term is 200
