How tall, in cm, is the stack of 8 cups?
Answer:
40 cm.

If 2 cups is 16 cm, and 4 cups are 20cm. You can multiply 4 by 2 to get 8. (20 x 2 = 40cm)
(16 divided by 2 = 8). ( 8 = the total length of each cup)
So...
( 8 cups are = to 40 cm)

Given right triangle ABC with altitude BD¯¯¯¯¯¯¯¯ drawn from vertex B to hypotenuse AC¯¯¯¯¯¯¯¯, find the lengths of AD¯¯¯¯¯¯¯¯, BD¯¯¯¯¯¯¯¯, and CD¯¯¯¯¯¯¯¯.
Answer:
AD = 1.96
BD = 6.72
CD = 23.04
Step-by-step explanation:
7/25 = AD/7
25AD = 49
AD = 1.96
24/25 = BD/7
25BD = 168
BD = 6.72
CD = 25 - 1.96 = 23.04
Please help me!!!!!!
Answer:
t=5.25x
Step-by-step explanation:
since X equals the number of egg cartons sold then we would have to multiply that by how much one egg carton costs (5.25$ each)
so if they sold 3 egg cartons the equation would be t=5.25*3.
(putting a variable next to a number means your multiplying it)
I hope I explained that clearly enough :P

A spinner has 8 equal spaces. If you spin it, what is the probability that you 2 points
spin a number greater than 5?
Answer:
78
Step-by-step explanation:
probability of getting a 5 which is 78.
Another way to look at this is that if we know the probability of the result being 5, then the probability of it not being 5 is just one minus that probability. We know that 5 is just one out of the 8 possibilities, so
P5=18
So the probability of not 5 is
Pnot5=1−P5=1−18=78

I have some stickers in my collection.
My sister has 29 more than I do.
Together we have 773 stickers. How
many stickers are in my collection?
Answer:
Step-by-step explanation:
s=y+29
s+y=773, using s from above makes this
y+29+y=773
2y+29=773
2y=744
y=372
So you have 372 stickers in your collection.

Matias is turning half of his backyard into a chicken pen. His backyard is a 24 meter by 45 meter rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Matias need?
Answer:
The length of fencing Matias needs is 51 meters
Step-by-step explanation:
The given parameters are;
The dimensions of Matias' backyard from which half is to be turned into a chicken pen = 24 m by 45 m
The orientation of the fence that is will be made for the chicken pen = Stretch diagonally across the backyard (from a corner to the opposite corner)
From the question, Matias' backyard is rectangular in shape
Therefore, by Pythagoras theorem;
The length of the diagonal fence = √((24 m)² + (45 m)²) = 51 m
Matias needs 51 meters of fencing for the diagonal fence.

Answer:
You would have to look at the explanation since there are multiple
Step-by-step explanation:
-7x + 1 would have to be greater than or equal to 15.
-7(2) + 1 = 15 so you would mark a filled in dot at 2 and point an arrow going to the right.
6x + 3 must be greater than or equal to -21.
6(-4) + 3 would equal -21 so you would mark a filled in dot at negative 4 with an arrow going to the right.

78 = d
can you solve this for me please?
Answer:
19: 106
20: 79
21: 70
Step-by-step explanation:
Circle upper left
The central angles all add up to 360 degrees
BC + CD + 148 = 360
But CD = BC
2BC + 148 = 360 Subtract 148 from both sides
2BC = 360 - 148 Combine
2BC = 212 Divide by 2
BC = 106
20
3 of the 5 arcs are marked as being equal.
Let each of them be called = x
3x + 41 + 82 = 360 Combine
3x + 123 = 360 Subtract 123 from Both sides.
3x = 360 - 123
3x = 237
x = 237 / 3
x = 79
BC = 79

Unless DE and FC are diameters, this can't be solved. I will assume they are.
FB + 48 + 22 = 180.
FB + 70 = 180
FB = 110
===========
FC = FB + BD + DC
180 = 110 + 22 + DC
180 = 132 + DC
DC = 180 - 132
DC = 48
===========
BC = BD + DC
BC = 22 + 48
BC = 70
PLEASE ANSWER HONESTLY (PLEASE BE HELPFULL I HAVE BEEN STUCK ON THIS PROBLEM) WILL MARK BRANIEST IF CORRECT (the question is in the picture below)
Answer:
52
Step-by-step explanation:
the angles on any triangle together equal 180 degrees. add up the two angles you know (36+92) and you get 128 degrees. then subtract that (128) from 180 and you get 52. 52 degrees is the missing angle.
Which of the following is equivalent to (2x^3)(7x^4)
Answer:
where are the answer choices
Step-by-step explanation:
Answer:
2x + 3 = 7x + 4
3 + 2x = 7x + 4
3 + 2x = 4 + 7x
3 + 2x = 4 + 7x
3 + 2x + -7x = 4 + 7x + -7x
2x + -7x = -5x
3 + -5x = 4 + 7x + -7x
7x + -7x = 0
3 + -5x = 4 + 0
3 + -5x = 4
3 + -3 + -5x = 4 + -3
3 + -3 = 0
0 + -5x = 4 + -3
-5x = 4 + -3
4 + -3 = 1
-5x = 1
x = -0.2
A radioactive substance decays at a rate of 25% every 10 years. Which equation represents the amount of the substance (S) remaining from 100 grams after 300 years?
Answer:
[tex]y = 100 * (0.75)^{30[/tex]
Step-by-step explanation:
Given
[tex]a =100[/tex] --- Initial Amount
[tex]r= 25\%[/tex] every 10 years
Required
The remaining amount after 300 years
To do this, we make use of:
[tex]y = a(1 - r)^T[/tex]
Where
r = decay rate
T = the period of decay
In 300 years, there are 30 periods of 10 years.
i.e.
[tex]T = \frac{300}{10}[/tex]
[tex]T = 30[/tex]
[tex]y = a(1 - r)^T[/tex]
[tex]y = 100 * (1 - 25\%)^{30[/tex]
[tex]y = 100 * (1 - 0.25)^{30[/tex]
[tex]y = 100 * (0.75)^{30[/tex]
in the question "what is 45% of 82" what is 82?
