The minute hand on a clock is 15cm long. what area does it pass over in 1 hour (pls show working)
Answer:
the 12 on the clock
Step-by-step explanation:
Answer:
94.2cm in 1 hour.
Step-by-step explanation:
In 1 hour, minute hand completes one round means makes a circle.
Radius of the circle(r)=15cm
Circumference of circular clock=2πr
=2×3.14×15=94.2cm
Therefore, the tip of the minute hand moves 94.2cm in 1 hour.

Susan opened a college savings account 4 years ago. She opened the account with an initial deposit of $3,000. Starting the next year, she deposited $1,000 on the same day each year. The account earns interest at an annual rate of 4.15% and is compounded annually. Susan hopes to have earned enough interest to pay for her first year of college tuition, which costs $7,100. What is the difference between her ending balance after 4 years and the cost of her tuition?
Answer:
$20
Step-by-step explanation:
multiply 100.00 x 5% which is 100x 0.05, then it will give you 5.
add 5, 4 more times which will give you 20
a stack of 500 pieces of paper is 1.875 inches tall derion guesses that each piece of paper is 0.015 inches thick. explain how you know that derions answer is not correct.
compute the thickness of each piece of paper. show your reasoning
Answer:
Derions answer is not correct becuase 500 x 0.015=7.5 inches. If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.
If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.

Answer:
I think it is by multiplying by 2.
Step-by-step explanation:
Even if it depends on the x, the constant of proportionality just goes by the multiple of 2 as you can see on the graph.
For example, the point that's on ( 2, y) on the graph is the start of it's proportional relationship that is on the line. Here is an example of how it is proportional:
hope it helps in a way:)
Answer:
X and Y have the same constant of proportionality. When X is 4 then Y is 4 as you can see on your picture you attached.
Help? question below
Answer:
12 shirts
Step-by-step explanation:
First, let x = # of shirts and y = total cost in $. Then create an equation with x and y representing each company. The first company is y = 9.65x + 43 and the second company is y = 8.40x + 58. Since we need to find the # of shirts that would result in the equal total cost, we need to find x when y is equal to the other. Thus here is the setup: 9.65x + 43 = 8.40x + 58, and we would get 1.25x = 15, so x = 12.

Sam has 6x + 8 dollars saved. Teresa has saved 14x + 32 dollars. Together they have $220 saved. How much money have they each saved individually?
Step-by-step explanation:
given,
dollars saved by Sam = 6x + 8
dollars saved by Teresa = 14x + 32
total money = $220
a/q
money saved by,
sam + Teresa = $220
so,
6x + 8 + 14x + 32 = 220
20x + 40 = 220
20x = 220 - 40 = 180
x = 180/20 = 9
x = 9
now,
money saved by,
Sam = 6x + 8 = 6(9) + 8 = $62
Teresa = 14x + 32 = 14(9) + 32 = $158
therefore,
money individually saved by Sam is $62 and by Teresa $158.

Answer:
Melinda adds $12 to her savings account each week and Marcus adds $14 each week
Melinda adds $2 less than Marcus
Step-by-step explanation:
Melinda:
135 - 75 = 60
60 ÷ 5 = 12
She saves $12 each week
Marcus:
y=14x+25
y=14x5+25
y= 70+25
y=95
95-25=70
70÷5= 14
Marcus saves $14 each week

Step-by-step explanation:
evaluate this expression when c= -2 and d= 2:
Step-by-step explanation:
you just have to put the given values in place of the variable names and then simply calculate.
(-2² + 2²) - 2(-2² - 2²) = (4 + 4) - 2(4 - 4) = 8 - 2×0 = 8
so, B is the right answer.
please remember the correct sequence of operations :
first are brackets.
then exponents.
then multiplications and divisions.
and then (at last) additions and subtractions.
and also please remember : multiplying a negative number with a negative number creates a positive result.
that is of course also true for squaring a negative number, as ² just means that the negative number is multiplied with itself.
now you also know the result of -2³, right ?
as this means -2 is multiplied 3 times by itself. what does that do to the sign ?
-2 × -2 = 4 (positive).
but now we have to multiply a third time
4 × -2 = -8 (because multiplying a positive number with a negative number creates a negative result).

Usually, when Landon makes bird food, he mixes 9 cups of seed with 6 tablespoons of maple syrup. However, today, he is short on ingredients. Describe a recipe that would make a SMALLER batch of bird food but still taste exactly the same.
Answer:
3 cups of seeds and 2 tablespoons of maple syrup
-OR-
6 cups of seeds and 4 tablespoons of maple syrup
Step-by-step explanation:
As this is a ratio of 9:6: "for every 9 cups of seeds, there is 6 tablespoons of maple syrup"
The original ratio is 3:2 "for every 3 cups of seeds, there is 2 tablespoons of maple syrup"
Using this ratio, we can infer that 3:2 or 6:4 would be a simpler answer for this problem. If there is doubt, it would be better to use 3:2 as it is the smallest ratio.
Anthony is building a cube-shaped box to store some of his smaller crafting supplies. The formula for the surface area of a cube is SA=6s2, where s is the side length of the cube. If he has a total of 200 in.2 of cardboard, can Anthony build a box where s=6 in.?
No, he needs 16 in.2 more cardboard.
No, he needs 232 in.2 more cardboard.
Yes, he will have 56 in.2 of cardboard left over.
Yes, he will have 128 in.2 of cardboard left over
Answer:
No, he needs 16 inches^2 more cardboard.
Step-by-step explanation:
Take the formula and substitute values into it. 6 * 6^2
Do the exponent first to get 6 * 36, and then complete that to get 216. Since he has 200 inches of cardboard and he would need 216, that means he would need 16 more square inches to make his cube.
