Answer:
25 cm^2
24 cm
Step-by-step explanation:
5*5 = 25 cm^2
Make sure not to forget the cm^2, otherwise you will get it wrong
10 + 14 = 24 cm
this is only perimeter so only cm
Answer:
25 cm²
24 cm
Step-by-step explanation:
Area of a Square: A = lw
Since the sides of a square are all the same, we have A = 5(5) = 25 cm²
Perimeter of a Rectangle: 2w + 2l
Simply plug it in:
P = 2(7) + 2(5)
P = 14 + 10
P = 24 cm

Onsider two concentric circles, one with radius r1 and the second with radius r2, where r1>r2. Suppose a line t is tangent to the circle with radius r1. How many points are in the intersection of t and the circle with radius r2
Answers
Answer:
0
Step-by-step explanation:
A tangent line is a line that touches the circle's circumference at only one point.
Given two concentric circles one with radius [tex]r_1[/tex] and the second with radius [tex]r_2[/tex], and [tex]r_1>r_2[/tex]. SInce [tex]r_2[/tex] is inside the smaller circle, there is no way it would intersect with the tangent line t.

Hasty generalization fallacy
Step-by-step explanation:
Fallacy can be said to be a reasoning which leads to the wrong interpretation of a statement or an argument. Although some people intentionally make fallacious statements just to score cheap points or to please the listening audience, but some make fallacious unknowingly, either due to carelessness or by being lackadaisical.
In this case the writer, without enough investigation and proof, comes to a very hasty conclusion that "all doctors are the same". This is termed a hasty conclusion because the writer only had dealings with just two docotors(Dr. Ames and Dr. Collins). So saying all doctors are the same just because of two instance is a rather rash statement.
Therefore, the fallacy commited by the writer here is a fallacy of hasty generalization.
Hasty generalization fallacy occurs when someone has a limited information on a population but makes a conclusion based on a larger population than he/she should.
A train leaves Miami at 3:00 PM. A second train leaves the same city in the same direction at 8:00 PM. The second train travels 145 mph faster than the first. Of the second train overtakes the first at 10:00 PM, what is the speed of each of the two trains
Answers
Answer:
The first train travels at 58 mph and the second train travels at 203 mph.
Step-by-step explanation:
The first train left Miami at 3:00 PM.
The second train left Miami at 8:00 PM.
Let the speed of the first train be x.
The second train travels 145 mph faster than the first, that is 145 + x
The second train overtakes the first at 10:00 PM
This means that at 10:00 PM, they were both at the same location.
That is 7 hours after the first train left and 2 hours after the second train left.
Speed is given as:
s = d / t
where d = distance traveled and t = time taken
For the first train, after 7 hours traveling at speed x:
x = d / 7
=> d = 7x _______(1)
For the second train, after 2 hours, traveling at speed 145 + x:
145 + x= d / 2
=> d = 290 + 2x ____(2)
Equating (1) and (2):
7x = 290 + 2x
=> 7x - 2x = 290
5x = 290
=> x = 290/5 = 58 mph
Therefore, the first train travels at 58 mph and the second train travels at 203 mph (58 + 145)
In the triangles, HG = MP and GK = PN. Triangles H G K and M P N are shown. Side H K has a length of 15 millimeters. Side M N has a length of 11 millimeters. Sides H G and M P are congruent. Sides G K and P N are congruent. Which statement about the sides and angles is true?
Answers
Answer:
m∠G > m∠P
Step-by-step explanation:
Given that:
HG = MP and GK = PN., Side H K has a length of 15 millimeters. Side M N has a length of 11 millimeters.
The triangle law for unequal sides states that if two sides are unequal. the angle opposite the longer side is greater than the angle opposite the shorter side. Since side HK has a length of 15 millimeters and Side MN has a length of 11 millimeters, the angle opposite side HK (which is m∠G) is greater than the angle opposite side MN (which is m∠P). That is m∠G > m∠P.

A) Integers,rational
B) Whole, Integers,rational
C) Integers,Irrational
D) Whole,Integers
Answers
The number -32 belongs to set : A) integers, rational
Rational numbers are terminating or repeating real numbers. Whereas, irrational numbers are the complement of rational number with real number being the universal set. These numbers are non terminating non repeating real number.
Integers are a subset of rational number. These are numbers not in fraction or decimal, or say with a denominator 1.
Whole numbers are subsets of integers which are positive, or say integers greater than equal to 1.
Given number : -32.
Since, the number is terminating, it is rational.
Further, it is not a fraction or decimal, hence integer.
But since the number is negative, not a whole number.
Therefore A) Integers, rational is correct option.

Which is the equation for a sphere with the center (2,-9,-1) and radius √r? a. (x + 2)2 + (y - 9)2 + ( z - 1)2 = r b. (x - 2)2 + (y + 9)2 + ( z + 1)2 = r c. (x - 2)2 + (y + 9)2 + ( z + 1)2 = √r d. (x + 2)2 + (y - 9)2 + ( z - 1)2 = r2
Answers
Answer: b. [tex](x-2)^2+(y+9)^2+(z+1)^2=r[/tex]
Step-by-step explanation:
The general equation of a sphere is : [tex](x - a)^2 + (y - b)^2+ (z - c)^2 = R^2[/tex], where (a, b, c) represents the center of the sphere, R represents the radius, and x, y, and z are the coordinates of the points on the surface of the sphere.
Given, Center of the sphere = (2,-9,-1)
Radius = √r
Then, the equation of the sphere would be
[tex](x - 2)^2 + (y - (-9))^2+ (z - (-1))^2 = (\sqrt{r})^2\\\\\Rightarrow\ (x-2)^2+(y+9)^2+(z+1)^2=r[/tex]
Hence, the correct option is b. [tex](x-2)^2+(y+9)^2+(z+1)^2=r[/tex] .

Answer:
Ratio of George age to Carl's age to Alex age = 1 : 12 : 4
Step-by-step explanation:
Let the age of Alex = A years
Age of George = G years
And age of Carl = C years
"Alex is 12 years older than George"
A = G + 12 ------(1)
"Carl is 3 times older than Alex"
C = 3A
C = 3(G + 12)
C = 3G + 36 ------(2)
"Sum of their ages is 68 years"
A + G + C = 68 ------(3)
By substituting the values of A and G in equation (3)
G + 12 + G + 3G + 36 = 68
5G + 48 = 68
5G = 20
G = 4 years
From equation (1),
A = 4 + 12 = 16 years
From equation
C = 3(4) + 36
C = 12 + 36
C = 48 years
Ratio of their ages = G : C : A
= 4 : 48 : 16
= 1 : 12 : 4

List the sides of ∆XYZ in order from shortest to longest if m∠X = 51, m∠Y = 59, and m∠Z = 70
Answers
Step-by-step explanation:
Angles and sides go hand-in-hand. Although I don't see the actual triangle that's used, and that can affect my answer, the side opposite of the shortest angle will be the shortest, the side opposite of the middle angle will be the middle, and the side opposite the largest angle will be the largest. For example, if the shortest angle (m∠X = 51) is the top vertex, the base side will be the shortest.
If f(x)=8-10x and g(x)=5x+4, what is he value of (fg)(-2)
Answers
Answer:
168
Step-by-step explanation:
We would like to multiply these two expressions together and then substitute -2 in for x to solve.
f(x) * g(x) = (8 - 10x) * (5x + 4)
We will use FOIL (first, outer, inner last):
(8 - 10x) * (5x + 4) = 8 * 5x + 8 * 4 + (-10x) * 5x + (-10x) * 4
Combining terms, we get:
f(x) * g(x) = 32 - 50x²
Plug -2 in for x:
32 - 50 * (-2)² = 32 - 50 * 4 = 32 - 200 = -168
The answer is thus 168.

B) 8 ways ( different outcomes )
Step-by-step explanation:
A) length of X = n
length of Y = n - k
number of ways to add k blanks in one continuous block
that would be n - k +1 and this because since we already have n-k blanks in y already
B ) how many ways to add two separate blocks of blanks
one size is ; i
one size ; k - i
The number of ways will be 8 since the block of blanks are separated into two blocks

FALSE, (2, 9) is not a solution to the set of inequalities given.
Step-by-step explanation:
Simply replace x by 2 and y by 9 in the inequalities and see if the inequality is true or not:
irst inequality:
[tex]y\geq 4x\\9\geq 4\,(2)\\9\geq 8[/tex]
so thi inequality is verified as true since 9 is larger or equal than 8
Now the second inequality:
[tex]y<x+2\\9<(2)+2\\9<4[/tex]
This is FALSE since 9 is larger than 4 (not smaller)
Therefore the answer to the question is FALSE, (2, 9) is not a solution to the set of inequalities given.
Sam was building a suspension bridge for the playground at an elementary school and needed some chain link and rope.He bought a total of 80 feet of materials. The chain link cost $2.00 per foot, and the rope cost $1.50 per foot. He spent a total of $135. How much of eacb did he buy?
Answers
Answer:
30 feet of chain link and 50 feet of rope
Step-by-step explanation:
Let's call the amount of chain link as x and the amount of rope as y. We can write:
x + y = 80 -- Equation 1
2x + 1.5y = 135 -- Equation 2
2x + 2y = 160 -- Equation 3 (Multiply Equation 1 by 2)
0.5y = 25 (Subtract Equation 2 from Equation 3)
y = 50 (Divide by 2)
x + 50 = 80 (Substitute y = 50 into Equation 1)
x = 30 (Subtract 50)
