extend pattern 1,4,9
Answer:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100......
Step-by-step explanation:
This is a list of perfect squares.
1 is the square of 1. ( 1 x 1 = 2)
4 is the square of 2. (2 x 2 = 4)
9 is the square of 3. (3 x 3 = 9)
So, the next number would be the square of 4 which is 16 ( 4 x 4)

Sonya has a collection of gold and silver coins.
65% of her collection consists of gold coins.
70 of her coins are silver.
What is the total number of coins in Sonya's collection?
Enter your answer in the space provided.
HELP PLEASE
Answer:
10.5
Step-by-step explanation:
65% of 70 is 45.5
So gold is 45.5 and silver is 54.5
so but45.5 + 54.5 = 100% but divide by 2
which is 50% but now we find 10% and 5%
10% = 7
5% = 3.5
now add 7 and 3.5 together
7+3.5 = 10.5

yes it is.
x = 4 and y = -3
Step-by-step explanation:
Solve simultaneously using elimination method:
equation 1 - equation 2
3x + y = 9 equation 1
-2x + y = 5 equation 2
_________
x = 4
plug 4 into any of the 2 equations and solve for y.
3(4) + y = 9
12 + y = 9
12-12 + y = 9-12
y = -3
The function f gives the weekly profit, in thousand dollars, that an airline makes on its flights from Boston to Washington D.C. when the ticket price is p dollars. Interpret the following.
f'(70) = 1.5
When the ticket price is _____, the weekly profit to the airline on flights from Boston to Washington is _____
Answer:
When the ticket price is $70, the weekly profit to the airline on flights from Boston to Washington is $1500.
Step-by-step explanation:
The function has the following format:
f(p)
That is, f is a function of p.
The derivative, f'(p), is the variation of f for the given value of p.
f'(70) = 1.5
p = 70, thus, ticket price of $70.
f'(70) = 1.5 means that the weekly profit to the airline on flights from Boston to Washington is 1.5 thousand dollars, that is, $1500.
Thus the correct answer is:
When the ticket price is $70, the weekly profit to the airline on flights from Boston to Washington is $1500.

What is the proportion for this problem?
It is already solved, just need the proportion.
Will mark brainliest to the correct answer!
Answer:
1/2
Step-by-step explanation:
Given the equation
6/12 = x/8
We are to find the proportion
Cross multiply
12 * x = 8 * 6
12x = 48
x = 48/12
x = 4
Hencethe value of x is 4
Substitute into the expression to get the proportion
6/12 = 4/8
In its lowest term;
6/12 = 4/8 = 1/2
Hence the required proportion is 1/2

Answer:
7 ?
Step-by-step explanation:
if im correct the total amount of toys was 15, dany broke one so thats 14. HALF of danys toys have speakers so
14 divided by 2 is 7
the answer is 7.
Answer:
7
Step-by-step explanation:
in total they were 15 toys , but 1 was thrown away. which means only 14 toys were left .
now half of the 14 toys have squeakers
so it can be calculated as :
14 ÷ 2 = 7

Help me with this please?? Find the indicated side length(s) of this triangle in simplified radical form
Answer:
b = 5√6
c = 10√5
Step-by-step explanation:
This is a 30-60-90 triangle
the hypotenuse is always twice the short leg
c = 2(5√2)
c = 10√5
The long leg is alway √3 times the short leg
b = √3(5√2)
b = 5√6
A baseball team has won 50 games of 75 played. The team has 45 remaining games to play. How many of the remaining games must a team win in order to win 60% of the total games played during the season?
A. 20
B. 21
C. 22
D. 23
Answer:
C. 22
Step-by-step explanation:
The team played 75 games and 45 remaining.
75+45=120
60% of 120 = 0.6×120= 72
The team must win 72 games and they already won 50 games so the team has to win 72-50=22 games more.
Suppose the length of each side of a square is increased by 5 feet. If the perimeter of the square is now 56 feet, what were the original side lengths of the square? A. 9 ft B. 11 ft C. 14 ft D. 36 ft
Answer:
D. 36 ft
Step-by-step explanation:
5 feet added to each of 4 sides is 20 feet
56 - 20 = 36
The equation shown below represents a logarithmic equation of base b.
a = logb(c)
Which set of numbers can a represent?
A.Only numbers > 0
B. Only numbers < 0
C All real numbers except 0
DAll real numbers
Answer:
C. All real numbers except 0
Step-by-step explanation:
It is the same as " numbers > 0"
Option (A) is correct.
What is logarithmic equation?"This equation will have all the terms but one be a logarithm and the one term that doesn’t have a logarithm will be a constant. In order to solve these kinds of equations we will need to remember the exponential form of the logarithm".
For the given situation,
The logarithmic equation, [tex]a = logb(c)[/tex]
⇒[tex]b^{c} = a[/tex]
Where a>0 , b>0 and b!=1
Thus a can represent, only numbers > 0.
Hence we can conclude that option (A) is correct.

Answer:
a) 42
b) 42/120
Step-by-step explanation:
Oof, I was just about done with answering this question but I deleted it all by accident so I had to rewrite it.
Anyways, the first part of it is correct.
The second part of it is a bit harder. See, this is conditional probability, which uses the equation that I've attached below.
For Event A, you'll need the total boys / total students:
0.44166
For Event B, you'll need the total counters / total students:
0.83333
Now, plug these values into the equation. The weird U thingy is called "Union". It basically means "and".
P(A and B) / P(B)
P(0.44166 * 0.8333) / P(0.8333)
0.36803 / 0.8333
This is about 0.44165, or 53/120

Find the area of a triangle with a base of 4 meters and a height of 14 meters.
Answer:
28 meters²
Step-by-step explanation:
Area of triangle = 1/2(base x height).
It is given that:
base = 4 meters
height = 14 meters
Plug in the corresponding numbers to the corresponding terms:
Area of the triangle = 1/2(4 * 14)
Area of the triangle = (4 * 14)/2
Area of the triangle = 56/2
Area of the triangle = 28 meters²
Answer:
The answer is 28 meters^2.
Step-by-step explanation:
To solve for the area of the triangle, start by using the area of a triangle formula, which is A= [tex]\frac{1}{2}[/tex] bh.
Next, plug in the information from the question into the formula. The formula will look like A= [tex]\frac{1}{2}[/tex](4)(14).
Then, solve the equation, and the final answer will be 28 meters^2.
