Step-by-step explanation:
Answer:
When you multiply or divide each side by 2, the signs stay the same. −16 < 4 and −4 < 1. When you multiply or divide by −2, the inequality sign reversed. 16 > −4 and 4 > −1.

Step-by-step explanation:
7-2=5 5/5=11. Isosceles Triangle The two equal sides of an isosceles triangle are each 42
centimeters. If the base measures 30 centimeters, find the height and the
measure of the two equal angles. Round your answer to the nearest tenth.
Answer:
1. H = 29 cm
2. θ = 44°
Step-by-step explanation:
1. We can find the height of the triangle by considering the isosceles triangle as two right triangles. The height can be found by using Pitagoras:
[tex] L^{2} = H^{2} + B^{2} [/tex]
Where:
L: is the sides of the isosceles triangle = 42 cm
B: is the base = 30 cm
H: is the height =?
Then, the height is:
[tex] H = \sqrt{L^{2} - B^{2}} = \sqrt{(42 cm)^{2} - (30 cm)^{2}} = 29.4 cm = 29 cm [/tex]
2. The two equal angles (θ) can be found using the following trigonometric identity:
[tex] cos(\theta) = \frac{B}{L} [/tex]
[tex] \theta = cos^{-1}(\frac{30 cm}{42 cm}) = 44.4^{\circ} = 44^{\circ} [/tex]
Hence, the two equal angles are 44°.

Given two intersecting CHORDS and their intercepted arcs, how do I determine the angles of intersection of the chords?
Answer:
Angles of Intersecting Chords Theorem
Step-by-step explanation:
If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
Answer: If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and it's vertical angle.
Step-by-step explanation: Example: In the circle, the two chords -PR and -QS intersect inside the circle. since vertical angles are congruent, m<1=m<3 and m<2=m<4
A pond holds 1920 gallons of water. There is a leak and the amount of water drops 20 gallons every hour. How much water is in the pond after 2 days ?

20 gallons * 48 hous =960 gallons
1920 - 960 =960 gallons.
A local yoga studio
charges a sign-up fee of
$55, plus $10 per class. A
second yoga studio
charges a sign-up fee of
$25 plus $12.50 per class.
A. Griffin
B. Gigi
Answer:
Let's call the first studio, yoga studio A.
Let's call the second studio, yoga studio B.
The equations:
Yoga Studio A: y=10x+55
Yoga Studio B: y=12.5x+25
So, for 12 classes:
Yoga Studio A: y=10(12)+55, y=175
Yoga Studio B: y=12.5(12)+25, y=175
These two numbers are equal, so Griffin is right.
For 10 classes:
Yoga Studio A: y=10(10)+55, y=155
Yoga Studio B: y=12.5(10)+25, y=150.
These two numbers are not equal, so Gigi is wrong.

Answer:
2120.85 ft^3
Step-by-step explanation:
Given data

Radius r= 5 ft
The volume of a cylinder is given as
V= πr^2h
Substitue
V= 3.142*5^2*27
V= 3.142*25*27
V= 2120.85 ft^3
Hence the volume is 2120.85 ft^3

The FBI wants to determine the effectiveness of their 10 Most Wanted list. To do so, they need to find out the fraction of people who appear on the list that are actually caught. Step 2 of 2 : Suppose a sample of 897 suspected criminals is drawn. Of these people, 322 were captured. Using the data, construct the 95% confidence interval for the population proportion of people who are captured after appearing on the 10 Most Wanted list. Round your answers to three decimal places.
Answer:
The answer is "0.359"
Step-by-step explanation:
Throughout the given question, in the sample of 897 suspected offenders were identified, 322 have also been convicted. So, the estimate of the population of individuals caught and been on the ten most attractive lists is then estimated:
[tex]\to \frac{322}{897} = 0.3589743.. \approx 0.359[/tex]

What is the value of the fourth term in a geometric sequence for which ay =
10 and r=0.5?
Answer here
I
SUBMIT
Answer:
a₄ = 1.25
Step-by-step explanation:
Given that,
First term of GP, a₁ = 10
The common ration of GP, r = 0.5
The nth term of the GP is given by :
[tex]a_4=a_1r^{n-1}\\\\a_4=a_1r^3\\\\a_4=10\times (0.5)^3\\\\a_4=10\times 0.125\\\\a_4=1.25[/tex]
So, the fourth term of the GP is 1.25.

The point shown in the graph tell about the panda which lives in the Washington, DC zoo that the age of panda is 36 months and the weight of panda is 82 kilograms.
How to read the data from the graph?In a graph, the line which is horizontal is known as the x-axis of the graph. The vertical line in the graph is called the y-axis of it. These axis helps to read the data from graph in following way-
The value of a point parallel to x axis in graph gives the value x-value. It is the value of parameter which is titled on x-axis.The value of a point parallel to y axis in graph gives the value y-value. It is the value of parameter which is titled on y-axis.In the given graph, the x-axis is labeled with age in months and y-axis is labeled with weight of panda.
The point with coordinates (36,82) tells that the age of panda is 36 months and the weight of the panda is 82 kilograms.
Hence, the point shown in the graph tell about the panda which lives in the Washington, DC zoo that the age of panda is 36 months and the weight of panda is 82 kilograms.

Write down the correct type of angle for angles A to E.
Answer:
Angle A- Obtuse angle
Angle B- Right angle
Angle C- Reflex angle
Angle D- Reflex angle
Angle E- Acute angle
Angle A is Obtuse angle, Angle B is Right angle, Angle C is Reflex angle, Angle D is Reflex angle and Angle E is Acute angle
What are Angles?An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
Obtuse angle is any angle greater than 90°
A right angle is an angle measuring exactly 90°
A reflex angle is an angle that is more than 180 degrees and less than 360 degrees.
Any angle that measures greater than 0° and less than 90° is called an acute angle.
By the definitions of these the angles are
Angle A- Obtuse angle
Angle B- Right angle
Angle C- Reflex angle
Angle D- Reflex angle
Angle E- Acute angle
Hence, Angle A is Obtuse angle, Angle B is Right angle, Angle C is Reflex angle, Angle D is Reflex angle and Angle E is Acute angle
