Answer:
(-5, -1), does not belong to the relation y = -x + 4
Step-by-step explanation:
From the question, we have;
The given ordered pair having a relation = (-5, -1)
The given relation, y = -x + 4
From the given relation, we get;
When y = -1
-1 = -x + 4
∴ -x = -1 - 4 = -5
x = 5
Similarly, when x = -5, we get;
y = -x + 4 = -(-5) + 4 = 5 + 4 = 9
y = 9
Therefore, (-5, -1), does not belong to the relation y = -x + 4 but (-5, -1), belongs to the relation y = x + 4
The estimated populations of two different countries in 2030 are shown in the table. What is the difference between the estimated population of countries A and the estimated population of country B in 2030 written in scientific notation.
country A: 1,300,000,000
Country B: 144,000,000
Answer: A (1.156x10(6)
Step-by-step explanation: IM DOING THE INTERIM TOOOOOO
Difference in the population of two countries will be 1.156 × 10⁶.
Given in the question,
Estimated population of two different countries in year 2030,
Country A → 1300,000,000Country B → 144,000,000Difference in population of both the countries = 1300,000,000 - 144,000,000 = 1156,000,000
Scientific notation of the population difference → 1.156 × 10⁶
Therefore, difference in the population of two different countries will be 1.156 × 10⁶.

In Triangle QRS, X is the midpoint of QR, Y is the midpoint of RS, and Z is the midpoint of QS.
Also, XR = 5, YS = 7, and QS = 20.
What is the perimeter of the Triangle XYZ?
Answer:
Step-by-step explanation:
I just answered this for someone else... here is the same answer I gave them
QR + RS +SQ = perimeter
2(XR) + 2(YS) + QS = perimeter ( b/c multiplication is communicative SQ=QS)
2*5 + 2 * 7 + 20 = perimeter
10 + 14 + 20 = p
44 = p

A roofer props a ladder against a wall so that the top of the ladder reaches a 20 foot roof that needs repair. If the angle of elevation from the bottom of the ladder to the roof is 46 degrees, what is the length of the ladder to the nearest foot?
Answer:
19.33 ft
Step-by-step explanation:
This analogy has to do with Pythagoras theorem.
We're given our angle of elevation to be 46°, and told that the height of the building to be 20 ft. Using Pythagoras theorem, we know that the given height is opposite to the angle of elevation, and thus, the required distance is adjacent to it.
Sin 46° = opp / hyp
Sin 46° = 20 / hyp
hyp = 20 / sin 46
hyp = 20 / 0.719
hyp = 27.82 ft
We've gotten the length of the ladder, our hypotenuse, to be 27.82. It's tied length we'd then use top find the needed length.
Cos 46° = adj / hyp
Cos 46° = adj / 27.82
adj = 27.82 * Cos 46
adj = 27.82 * 0.695
adj = 19.33 ft
Therefore, the required length is approximately equal to 19.33 ft
63 : 21 = __ : 3
I need help pls a quick answer would be great. Thanks!
Answer:
9 : 3
Step-by-step explanation:
To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...
63 / 7 = 9
Therefore 63 : 21 = 9 : 3

3a+4(5a - 4)=
5b -2(5a -b) + 10a
Answer:
17a - 16
7b
Step-by-step explanation:
Given the following expressions
3a+4(5a - 4)=
Expand
3a + 4(5a)- 4(4)
= 3a + 20a - 16
= 17a - 16
For the expression
5b -2(5a -b) + 10a
Expand
5b - 2(5a)-2(-b) + 10a
5b - 10a + 2b + 10a
= 5b + 2b -10a + 10a
= 7b + 0
= 7b

Answer/Step-by-step explanation:
How many total fish is Dr. Howser planning on buying?
BOTH tanks hold 120 gallons
Tank A :
3 every 10 --> 120/10 ---> 12
So multiply 3 and 12 ----> 36
36 fishes in tank A
Tank B:
6 every 40 -----> 120/40 ----> 3
So multiply 6 by 3 ----> 18
18 fishes are held in tank B
Add them together:
18 + 36 ----> 54
ANSWER : Dr. Howser is planing on purchesing 54 fish all together.
What will be the ratio of the number of small fish he buys to the number of large fish that he buys
Small ---> 36 fish
Large ---> 18 fish
Small : Large ----> 36:18
