There are 16 girls and 18 boys in a class. The teacher chooses a student's name at random to answer a question.
What is the probability that the teacher chooses a girl to answer the question?
A. 1/34
B. 1/16
C. 8/17
D. 8/9
Answer:
It would be 1/34 or 1/16.
Step-by-step explanation:
Add up how many kids there are in total and then see how many girls there are and write it like this: 18/34. Since it says a girl then you would do it as 1/34 or 1/16 it depends on how you look at it and or how you understand what the question is talking about.
Jeremie bought 5 pounds of bananas for $4.45. How much is 1 pound of bananas? Show or explain your reasoning
what is the strategies for this math problem?
Answer:
1 pound of bananas is 0.89
Step-by-step explanation:
Money over quantity 4.45/5
that means you divide so heres the layout
4.45/5 = x/1 so that is
5x=4.45 divide 5 so that gives us our variable 5÷5 that cancels out five 4.45 divide by 5 is 0.89
so for every pound of bananas is 0.89
And you would use Unite Rate as your strategy
Answer:
for 1 pound of banana...it is 0.89
Step-by-step explanation:

You invest $1,000 in an account with 6 % interest, compounded annually. Assume you do not touch the money or add money other than the earned interest.
How much money will you have in the account after 10 years?
(A) $ 1790.85
(B) $ 109951.16
(C) $ 538.62
(D) $ 1600
Answer:
A) 1790.85
Step-by-step explanation:
Hi there!
In order to solve this problem, you’ll need to use the compound interest formula [tex]x = p(1 + \frac{r}{n} )^n^t[/tex]
p will be your principle, or starting amount, which is 1,000.
r will be your percentage, which is 0.06.
n will be the amount of times interest is compounded, since this question says compounded anually, your compound will be 1.
t is the time in years it is compounded, which is 10.
When the numbers are plugged in, we get [tex]x = 1,000(1 + \frac{0.06}{1})^1^0[/tex]
When we solve for this, we get 1790.85.
Hope this helps! :)

Write an equation in Slope Intercept Form given the points (2, 3) and (-1, -12)?
Answer:
y = 5x -7
Step-by-step explanation:
first find the slope using the formula y2-y1/x2-x1
-12 -3 -15
--------- = ---- = 5
-1 -2 -3
slope: 5
Now to find the intercept plug in the slope and the numbers into the equation then solve
y-y1=m(x-x1)
y - 3 = 5 (x -2)
y -3 = 5x -10
+3 +3
y = 5x -7

You receive an inheritance of $15,500, and you place the full amount into a bank account. The bank pays a simple interest rate of 7.5% per year. How much interest have you earned after three years?
Answer:
After three years you have earned $3,755.60
Step-by-step explanation:
The first year you start with $15,500 on account and earn $1,162.50 as interest
At the end of the first year the bank account is $16,662.50
The second year you start with $16,662.50 and earn $1,249.69 as interest
So at the end of the second year you have a sum of $17,912.19
Then on the third year you start with $17,912.19 and earn an interest of $1,343.41
So at the end of the third year the total of the bank account is $19,255.60
Now, if you sum the three interests $1,162.50+$1,249.69+$1,343.41 the total is $3,755.60 and this is your answer.
Answer:
$3488 on Knewton
Step-by-step explanation:
Currently there are 691,255 trees in a national forest. A park ranger discovered that an untreatable disease is killing the
trees at a rate of 1.5% every year.
Lett represent the number of years after the current date. Determine the inequality that can be used to model when there
will be no more than 621,859 trees, and then solve the inequality for t.
The inequality which will represent the disease killing of trees in the national forest is 691255[tex]0.985^{t}[/tex]<621859 and the value of t is t<7.
What is inequality?An inequality is just like an equation which is presented in greater than sign, less than signs. It also shows relationship between variables like an equation does.
How to form inequality?Total trees present in the beginning=691255
rate at which trees are killed by untreatable disease=1.5%
So the inequality can be formed as under:
691255[tex](1-0.015)^{t}[/tex]<621859
[tex](0.985)^{t}[/tex]<621859/691255
[tex](0.985)^{t}[/tex]<0.89960
[tex](0.985)^{t}[/tex]<[tex](0.985)^{7}[/tex]
By equating we find that t<7.
Hence if 691255 trees are present in the beginning then they will last for more than 7 years to reach 621859.

Answer:
It should be that they both have the same area.
Step-by-step explanation:
since it's HALF the paper, the area should be the same. If you said the width of the paper was 8 inches and the length was 10, then the area would be 80 inches squared. Cut it in half for Calvin's paper and the area would be 40 inches squared, the same with Matthew's.

Answer:
x = 8.6 cm
Step-by-step explanation:
Reference angle = 35°
Opposite side length = x
Hypotenuse = 15 cm
Apply trigonometric ratio to find x
Thus:
[tex] sin(35) = \frac{x}{15} [/tex]
Multiply both sides by 15
[tex] sin(35)*15 = x [/tex]
8.60364654 = x
x = 8.6 cm (nearest tenth)

14 candy bars cost $5.20. How much would one cost? What is the unit rate?
Answer:
$0.37
Step-by-step explanation:
You can write this equation as, x=$5.20÷14.
This is because we know we are trying to find the x value for 1 candy bar. and 14 costs $5.20 in total. 14÷14=1. Therefore, we essentially divided the total sum among each individual candy bar. (example: if you wanted to find the value of 2 candy bars, you would take half of 14 and divide $5.20 by 7). $5.20÷14=$0.37 or 37 cents per candy bar.
Writing this as a rate is simple; it's $0.37/candy bar

B. City P is above sea level and City R is below sea level
Step-by-step explanation:
A. City R is negative meaning it is below sea level however City Q is 0 meaning it is at sea level, so this statement is false.
C. Once again, City P is positive meaning it is above sea level but City Q is 0 meaning it is at sea level, so this statement is false.
D. Like before, City P is above sea level and City Q is at sea level not below, so this is, once again, false.
