2 1/10
-2 1/1
-1 1/10
11/10
Answer:
Step-by-step explanation:
slope = m
m = y2-y1 / x2 - x1
m = (-4) - 7 / (-6) - (-4)
m = -11 / (-6) + 4
m = -11 / -2
m = 11/2

16. A radioactive isotope has a half-life of 13 hours. Find the amount of the isotope left from a 400-milligram
sample after 65 hours. If necessary, round your answer to the nearest thousandth.
a. 25 mg
c. 0.049 mg
b. 7.692 mg
d. 12.5 mg
Please help. I only see answers for 52 hours
Answer:
Without the math: 65 hours is 5 half-lives
13 hrs = 1/2
26 hrs = 1/4
39 hrs = 1/8
65 hrs = 1/32
(1/2)^5 = 1/32
400 mg / 32 = 12.5 mg that is, after 5 half-lives

The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?
Answer:
Base = 18 inches
Height = 54 inches
Step-by-step explanation:
The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?
The area of a parallelogram is given as:
Base × Height
Height = h = 3b
Area = 972 square inches
We substitute
972 = b × 3b
972 = 3b²
Divide both sides by 3.
b² = 972/3
b² = 324
b = √324
b = 18 inches
Solving for h
h = 3b
h = 3 × 18
h = 54 inches
Therefore,
Base = 18 inches
Height = 54 inches

a. 8
b. 12
c. 6
d. 9
Answer:
B.12
Step-by-step explanation:
For your first draw you have 4 possible options, then on your second draw you have 3 possible options since you took out a pair. So to figure out the number of possible outcomes you simply multiply the possibilities by each other to get the number of possible outcomes.

Step-by-step explanation:
john is a proud owner of a herd of cows 12 of them are brown and 32 are black what is the ratio of brown cows to the total number of cows?
Answer:
12:44, or if simplified 3:11
Step-by-step explanation:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Similarly, the ratio of lemons to oranges is 6∶8 (or 3∶4) and the ratio of oranges to the total amount of fruit is 8∶14 (or 4∶7).
Answer:
3 : 11
Step-by-step explanation:
Total number of cows = 32 + 12 = 44
Brown cows : Total
12 : 44 =
3 : 11
A parallelogram with a height of 2x+3 has an area listed below. What is the length of the base of the parallelogram? 2x^2+13x+15
Answer:
x+5
Step-by-step explanation:
I thought what 2 numbers if multiplied made 15
also 2x+3 already has a 3
so I'm guessing 3 and 5
then I put them next to each other
(2x+3) ( +5)
I put a x in the second parenthesis as a guess because the area had a 2x^2 in it . that could only happen with 2x * x
so (2x+3) (x+5)

Which two of the following numbers are rational?
1/3
.10
.π
√2
Answer:
1/3, 0.10
Step-by-step explanation:
Rational numbers can be expressed as a fraction of two integers.
1/3 is rational. When it is expressed as a fraction, it's 1/3. 1 is an integer, and 3 is an integer
0.10 is rational. It can be rewritten to be expressed as the fraction 1/10; 1 is an integer, and 10 is an integer.
.[tex]\pi[/tex] is irrational, because when expressed as a fraction, it is 1/[tex]\pi[/tex]. 1 is an integer, but [tex]\pi[/tex] is not. Both numbers need to be integers in order to be rational. Therefore, it is irrational
√2 is irrational. When expressed as a fraction, it's √2/1. √2 is not an integer. 1 is an integer. However, both numbers have to be integers in order to be rational. Therefore, √2 is not rational.
Uma professora de artes pediu aos alunos para montarem mosaicos unindo peças. Nesse mosaico, essas peças deveriam ficar sempre ligadas pelos vértices, não poderiam se sobrepor e não deveria sobrar espaço entre elas. Além disso, para fazer esse mosaico, essa professora solicitou que todos os alunos utilizassem octógonos regulares, como o que está apresentado abaixo.
M100839H6_1
Para compor esse mosaico, junto com esses octógonos, os alunos tinham à sua disposição as peças do quadro abaixo.

Answer:

Step-by-step explanation:
Answer:
é a letra D (II, III e IV)
Step-by-step explanation:
se você reparar no ângulo interno da figura do octógono está mostrando 135º e a primeira figura que no caso não encaixa mostra 60º, fazendo essa soma daria um total de 195º, o que passa de 180º que é a metade de uma circunferência, então não daria certo, ficaria uma parte sobrando, não se encaixando no mosaico.

Step-by-step explanation:
Amy spent $90 at the store. She spent 1/3 of her money on food, 1/6 of her money on school supplies, and 1/9 of her money on soda. How much did she spend on school supplies?
Given:
Amy spent $90 at the store.
She spent [tex]\dfrac{1}{3}[/tex] of her money on food, [tex]\dfrac{1}{6}[/tex] of her money on school supplies, and [tex]\dfrac{1}{9}[/tex] of her money on soda.
To find:
How much did she spend on school supplies?
Solution:
According to the given information, Amy spend [tex]\dfrac{1}{6}[/tex] of her money on school supplies.
Amy spent $90 at the store. So,
Money spend on school supplies = [tex]\dfrac{1}{6}\times 90[/tex]
= [tex]15[/tex]
Therefore, Amy spend $15 on school supplies.
Ian is borrowing $1000 from his parents to buy a notebook computer. He plans to pay them back at the rate of $60
per month. Ken is borrowing $600 from his parents to purchase a snowboard. He plans to pay his parents back at
the rate of $20 per month. a) Write an equation that can be used to determine after how many months the boys will owe the same amount.
b) Determine algebraically and state in how many months the two boys will owe the same amount. State the
amount they will owe at this time.
c) Ian claims that he will have his loan paid off 6 months after he and Ken owe the same amount. Determine and
state if Ian is correct. Explain your reasoning.
A = 10 months
B = First part, the two equations:
Ian: y = 1000 - 60x, where x is the number of months and y is the remaining balance owed.
Ken: y = 600 - 20x.
They will be equal at 1000 - 60x = 600 - 20x
Second part: Solve the equation. Note, if you're equation is incorrect, solve it anyway because you will still get some credit!
1000 - 60x = 600 - 20x
1000 = 600 + 40x
400 = 40x
x = 10 months
y = 600 - 20(10) = 600 - 200 = $400 still owed.
C =
Solve Ian's equation for y = 0, when no money is owed.
1000 - 60x = 0
1000 = 60x
x = 16.66666.... or 17 months.
Ian will not be paid off 6 months after he and Ken owe the same amount. He will still owe money.
Alternatively, six months after 10 is 16 months,
and y = 1000 - 60(16) = 1000 - 960 = 40. He will still owe $40 at 16 months, so he is not paid off.
