In a coin jar the ratio of dimes to pennies is 3 to 8. The number of pennies in the jar is 32. Answer the following questions based on this ratio. (Show ALL work.) *a) Why can’t the number of dimes be 10? Justify your answer by setting up & solving a proportion.
this is Solving Proportions
Answers
Answer:
Step-by-step explanation:
3 is to 8 as x is to 32
3/8=x/32
x=12
The number of dimes cannot be 10 because the number of dimes in the jar will be equal to 12.
What is the ratio?The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.
As per the data in the question,
The ratio of Dimes to pennies: 3 : 8
Number of Pennies in jar = 32
Assume that the number of Dimes in the jar is x.
So, the number of dimes will be,
x = (32 × 3)/8
x = 12 Dimes.

x = 23.33333
y = 35
Step-by-step explanation:
3x+2y=70
Geometric figure: Straight Line
Slope = -3.000/2.000 = -1.500
x-intercept = 70/3 = 23.33333
y-intercept = 70/2 = 35
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 35/1 so this line "cuts" the y axis at y=35.00000
y-intercept = 70/2 = 35
Calculate the X-Intercept :
When y = 0 the value of x is 70/3 Our line therefore "cuts" the x axis at x=23.33333
x-intercept = 70/3 = 23.33333
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 35.000 and for x=2.000, the value of y is 32.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 32.000 - 35.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -3.000/2.000 = -1.500
Geometric figure: Straight Line
Slope = -3.000/2.000 = -1.500
x-intercept = 70/3 = 23.33333
y-intercept = 70/2 = 35

Jasmine buys 3 T-Shirts and 3 Hats for $11.25. The next day, he buys 4 T-Shirts and 2 Hats for $10. How much does each T-Shirt and each Hat cost? Write a system of equations that can be used to solve the problem. Then solve the problem.
Answers
Answer: Each shirt costs $1.25, and each hat costs $2.5.
Step-by-step explanation:
Let x= Cost per T-shirt, y = Cost per Hat.
As per given,
3x+3y=11.25 (i)
4x+2y=10 (ii)
Multiply 4 to equation (i)
12x+12y=45 (iii)
12x+6y= 30 (iv)
Eliminate (iv) from (iii), we get
6y= 15
⇒ y = 2.5
Put value of y in (i)
3x+3(2.5)=11.25
⇒3x+7.5=11.25
⇒3x= 3.75
⇒x= 1.25
Hence, each shirt costs $1.25, and each hat costs $2.5.

When you have problems like this you simply ask yourself what number do I have to multiply by 23 to get 6? This is how you might read this mathematical expression. So how do we solve the problem?
Well if x is the number that we have to multiply by 23 to get 6 that means that if we divide 6, 26 times we get x. So, x would be 6/23.

When a biased coin is thrown 4 times, the probability of getting 4 heads is
16
81
Work out the probability of getting 4 tails when the coin is thrown 4 times.
Answers
Answer:
1/81
Step-by-step explanation:
P(H,H,H,H)=16/81
fourth root of 16/81= 2/3
so the probability of getting tails would be 1/3
probability of getting 4 tails would be:
P(T,T,T,T)=(1/3)^4
=1/81
The probability of getting 4 tails when the coin is thrown 4 times is 1/81
How to determine the probability?We have:
P(Head 4 times) = 16/81
This means that:
P(Head)^4 = 16/81
Take the 4th root of both sides
P(head) = 2/3
The probability of a tail is calculated as:
P(tail) = 1 - P(Head)
This gives
P(tail) = 1 - 2/3
P(tail) = 1/3
When thrown 4 times, we have:
P(tail)^4 = (1/3)^4
P(tail) = 1/81
Hence, the probability of getting 4 tails when the coin is thrown 4 times is 1/81
