The sum of two numbers is 41. The larger number is 21 more than the smaller number. What are the numbers
Step-by-step explanation:
a+b=41
let larger number be a and smaller be b
a=21+b
placing value of a in a+b=41
21+b+b=41
2b=41-21
b=20÷2
b=10
so a=21+10
=31
the numbers are 21 and 10.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, The sum of two numbers is 41.
let "x" be the smallest number.
Since The larger number is 21 more than the smaller number.
thus,
the larger number = 21 + smaller number
The larger number = 21 + x
Thus, sum = 41
x + 21 + x = 41
2x = 20
x = 10
So,
the Largest number = 21 + 10
Therefore, The largest number and the smallest number are 21 and 10 respectively.

Two expressions are shown below:
1. 514÷23
2. 514×32
Without solving these expressions, determine if they are equivalent. How do you know? (Please help..)
Answer:
Clearly they are not equivalent because division will get you a smaller number ( except when decimals are in used or special cases ) as an answer and division times the number that will oppositely get you a bigger number ( again, except the decimal or special cases )

Step-by-step explanation:
Continental Drift Theory says that all the continents used to be one landmass called Pangaea, and that proves how glaciers, fossils, and plants are on different sides of oceans.
(Is proven to be true.)
So that leaf must have came from a tropical landmass like Australia, Africa, or South America.
Since C is the one that explains Plate Tectonic Theory, it is correct.

Sadie is saving her money to buy a new pony, which costs $600. She has already saved $75. She earns $50 per week working at the stables and wonders how many weeks it will take to earn enough for a pony of her own. How many weeks will Sadie have to work to earn enough to buy the pony?
A) 8 weeks
B) 10 weeks
C) 11 weeks
D) 12 weeks
Answer: C
Step-by-step explanation:
My answer is correct because, if Sadie gets 50 per week then we can just multiply it by 10 and that equals 500. But since we have 75 dollars already we cant multilpy it by 11 but if we times it by 10.5 that equals 525 and if we add 75 dollars that equals 600. but since we get the money every week we have to round that and that would equal 11 weeks.

Solve the following system of equations algebraically:
y = x^2 – 10x + 15
y = 2x – 5
Answer:
(2, -1)
(10, 15)
Step-by-step explanation:
Subtract the second equation from the first
y = x² – 10x + 15
- (y = 2x – 5)
————————————
0 = x² - 12x + 20
Factor
(x - 2)(x - 10) = 0

TRA
WUNNIN
Answer:
Since Michael traveled 63 miles while Leah traveled 45.48 miles, Michael traveled 17.51 extra miles.
Step-by-step explanation:
Given that Walltown is 25 miles east of Park City, and Park City is 38 miles south of Edenton, and Michael drove from Edenton to Park City and then to Walltown while Leah drove straight from Edenton to Walltown, to determine about how much farther did Michael drive than Leah, the following calculation must be performed, using the Pythagorean theorem:
Michael:
38 + 25 = 63
Leah:
25 ^ 2 + 38 ^ 2 = X ^ 2
625 + 1,444 = X ^ 2
2,069 = X ^ 2
√2,069 = X
45.48 = X
63 - 45.49 = 17.51
Therefore, since Michael traveled 63 miles while Leah traveled 45.48 miles, Michael traveled 17.51 extra miles.

Hence Mr Drew will get 20 pieces of a Quarter
Step-by-step explanation:
From the question we are told that:
Money changed [tex]m= 5[/tex]
Number of coins [tex]N=20p[/tex]
Generally the equation for coin change into x is mathematically given by
[tex]x=\frac{m}{N}[/tex]
[tex]x=\frac{5}{20}[/tex]
[tex]x=\frac{1}{4}[/tex]
Therefore oin change into x is given as

(5h – 3)(5h – 3)
Answer: -30h +9
Step-by-step explanation:
Answer:
25h²-30h+9
Step-by-step explanation:
we need to multiply binomials
to multiply binomials using the FOIL method, we first multiply the First terms (F for first) together (in this case, 5h and 5h)
That gives us 25h²
Next up, we do the Outer terms (O for outer), which in this case are 5h and -3. This gives us -15h
then, we do the two Inner terms, (I for inner) which are -3 and 5h. This gives us -15h
finally, we do the two Last terms (L for last), which are -3 and -3. This gives us 9
here's what we have from doing FOIL:
25h²-15h-15h+9
we can combine the 2 -15h's together to get:
25h²-30h+9

A line passes through the point (-8, 2) and has a slope of -1
Answer:
y=-x-6
Step-by-step explanation:
Plug this into the equation y-y1=m(x-x1) where m is the slope. We know that it passes through (-8,2) so y1=2 and x1=-8. We also know that the slope is -1 so we can now fill in the equation. y-2=-1(x--8). We can change x--8 to x+8 so y-2=-1(x+8). Simplify this to get y-2=-x-8. You want to isolate y so you have to add 2 on both sides. y=-x-6. Therefore, the equation is y=-x-6.

In ΔOPQ, q = 6.5 inches, o = 8.6 inches and ∠P=55°. Find ∠Q, to the nearest 10th of an degree.
Answer:
∠Q = 35.5°
Step-by-step explanation:
We are given;
q = 6.5 inches
o = 8.6 inches
∠P = 55°
Let's first use cosine rule to find p.
p² = q² + o² - 2qo cos P
Plugging in the relevant values;
p² = 6.5² + 8.6² - (2 × 6.5 × 8.6 × cos 55)
p² = 42.25 + 73.96 - 32.0629
p² = 84.1471
p = √84.1471
p = 9.17 inches
Using sine rule, we can find ∠Q;
p/sin P = q/sin Q
sin Q = (q•sinP)/p
sin Q = (6.5 × sin 55)/9.17
sin Q = 0.5806
Q = sin^(-1) 0.5806
Q ≈ 35.5°

The length of one side of a square is 3m^4. What is the area of the square? (A = I x w)
a. 3m^4
b. 6m^8
C. 9m^8
d. 6m^6
============================================================
Explanation:
Each side of the square is the same, so we have length = width in this case.
Length = 3m^4
Width = 3m^4
Area = (length)*(width) = (3m^4)*(3m^4) = (3*3)*(m^4*m^4) = 9m^8
Note how m^4*m^4 leads to m^8. We add the exponents.
The general rule is a^b*a^c = a^(b+c).
Find value of trigonometric ratio round your answer to four decimal places
tan a
Answer:
tan A = .3429
Step-by-step explanation:
Tangent = Opposite over Adjacent
The opposite of ∠A = 12 and the adjacent = 35
so tan A = 12/35 which equals .3428571492
The question asks us to round to four decimal places
Hence, the answer is .3429

Find the slope of the line through the pair of points.
(13, 5) and (3,5)
Answer: 0
Step-by-step explanation:
So the slope of a line is equal to rise over run, or the change in x over the change in y. We can solve for the change in x and the change in y by finding their differences. For the math, we use the formulas y2 - y1/x2 - x1. Filling in this formula we get, (5-5)/(3-13), which is equal to 0/10. Because 0 divided by anything is 0, the answer here is 0.

Bella paints rows of flowers for an art piece. There are 9 flowers in each of the 6 rows. She paints 1/3 of the flowers yellow. How many yellow flowers are there?
Answer: 18 yellow flowers
Step-by-step explanation:
There are 9 flowers in each of the 6 rows. The total number of flowers planted is therefore:
= 6 rows * 9 flowers per row
= 54 flowers
A 1/3 of these flowers were yellow flowers so the number of yellow flowers planted is:
= 1/3 * 54
= 54/3
= 18 yellow flowers
