What would be the fourth and fifth figures? How many dots will be in the 100th figure?
Answer:
4th=8 dots
5th=10 dots
100th=200 dots
Step-by-step explanation:
Since you’re adding two dots each time, it will always bed double the figure number.
4th=8 dots
5th=10 dots
100th=200 dots
Answer:
The fourth figure is 8 Dots
The fifth figure is 10 Dots
The hundredth figure will be 200 Dots
Step-by-step explanation:
The figure dots increase by two so we multiply the dot number by the amount of increase
which means
The Fourth figure have 4 dots so 4 × 2=8
The Fifth figure have 5 dots so 5 × 2 =10
The hundredth figure have 100 dots so 100 × 2 =200

which are composite numbers?
49
35
32
41
47
Answer:
49, 35 and 32 are composite and the rest are orime numbers
Answer:
[tex] \boxed{ \bold{ \huge{\boxed {\sf{49 \: , \: 35 \: , \: 32}}}}}[/tex]
Step-by-step explanation:
Composite numbers are whole numbers that can be divided by numbers other than itself and 1.
Among 49 , 35 , 32 , 41 and 47,
: 49 , 35 and 32 are composite numbers.
49 is a composite number as it comes in the multiplication table of 1 , 7 and 49 . So, this means it comes in the table of more than 2 numbers. 35 is a composite number as it comes in the multiplication table of 1 , 5 , 7 and 35.32 is a composite number as it comes in the multiplication table of 1 , 2 , 4 and 16. 41 is not a composite but a prime number as it comes in the multiplication table of only 1 and 41 [ 1 and itself ] 47 is not a composite but a prime number as it comes in the multiplication table of only 1 and 47 [ 1 and itself ]Hope I helped!

Stuck on this 6/9 times 3
Answer:
2
Step-by-step explanation:
6/9 * 3
First you can either simplify this to make it easier or directly multiply. Simplify it by dividing 3 on the 9.
6/3=2
Or you can multiply and it would be 18/9, because 6*3=18.
18/9=2

James read that bears can weight up to 125 kg. He wants to convert this to pounds so he can understand how heavy that really is. Convert the bears weight to pounds. (1kg = 2.205 lbs)
Answer:
275.63 pounds
Step-by-step explanation:
To convert it to pounds, multiply the weight in kg by 2.205
125(2.205)
= 275.63 pounds
Answer:
125 kg = 275.578 lbs
Step-by-step explanation:
1 Kilogram (kg) is equal to 2.2046226218 pounds (lbs). To convert kg to pounds, multiply the kg value by 2.2046226218. For example, to convert 4 kilograms to pounds, multiply 4 by 2.2046226218, that makes 4 kg is 8.81849049 lbs.

through(5,4), parallel to y=(1/5)x-5
Answer:
y = 1/5x + 3
Step-by-step explanation:
parallel lines have the same slope
y = 1/5x + b
4 = 1/5(5) + b
4 = 1 + b
b = 3
y = 1/5x + 3

4. Evaluate the function at each specified value of the independent variable and simplify. (If an answer is undefined, enter UNDEFINED.) 5. Evaluate the function at each specified value of the independent variable and simplify. (If an answer is undefined, enter UNDEFINED.)
Answer:
See below.
Step-by-step explanation:
4)
So we have the function:
[tex]g(y)=7-6y[/tex]
And we want to find:
[tex]g(s+1)[/tex]
So, substitute y for (s+1):
[tex]g(y)=7-6y\\g(s+1)=7-6(s+1)\\[/tex]
Distribute:
[tex]g(s+1)=7-6s-6[/tex]
Subtract:
[tex]g(s+1)=-6s+1[/tex]
5)
So we have the function:
[tex]h(t)=t^2-2t[/tex]
And we want to find:
[tex]h(x-3)[/tex]
So, substitute t for (x-3):
[tex]h(t)=t^2-2t\\h(x-3)=(x-3)^2-2(x-3)[/tex]
Square and distribute:
[tex]h(x-3)=(x^2-6x+9)+(-2x+6)[/tex]
Combine like terms:
[tex]h(x-3)=(x^2)+(-6x-2x)+(9+6)[/tex]
Add:
[tex]h(x-3)=x^2-8x+15[/tex]
And those are our answers :)

there are 300 window for b buildings. assuming there is an equal number of windows per building, how many windows does each building have
Answer:
[tex] x = \frac{300}{b} [/tex]
Step-by-step explanation:
We are given that, "b" number of buildings has 300 windows.
Let b represent the number of buildings.
Let x represent the number of windows per building.
Thus, the following equation can be used to expressed the number of windows for b buildings:
Number of buildings*number of windows per building = 300 windows
[tex] x*b = 300 [/tex]
The number of windows each building has would be:
[tex] \frac{x*b}{b} = \frac{300}{b} [/tex]
[tex] x = \frac{300}{b} [/tex] windows per building
The U.S department of Agriculture reported that 45 out of every 115 milk drinkers drink skim milk. If a store owner orders 23 gallons of milk, how many should be skim

Wilma has 21 coins in her pocket made up of dimes and quarters. If the total value of the coins is $3.45, how many of each coin does she have?
Answer:
x = 12
y = 9
12 coins of dimes
9 coins of quartes
Step-by-step explanation:
x ---> coins of dimes
y ---> coins of quartes
x + y = 21
0.1x + 0.25y = 3.45 * 100
x + y = 21 L1
10x + 25y = 345 L2
x = 21 - y
Reemplace in L2
10(21 - y) + 25y = 345
210 - 10y + 25y = 345
15y = 345 - 210
15y = 135
y = 9
x = 21 - y
x = 21 - 9
x = 12
