5:9 If that's what you meant
Step-by-step explanation:
Answer:
57.6% have allergies
42.4% have no allergies
Step-by-step explanation:
We only need to consider the students who speak two languages according to the question.
To find the percent with allergies, divide the number of students with allergies by the total number of students (that speak two languages).
19/33 = 0.5757 = 57.6%
To find the percent without allergies, divide the number of students without allergies by the total number of students (that speak two languages).
14/33 = 0.4242 = 42.4%
Check your work by adding the percentages to make sure they equal 100%
57.6 + 42.4 = 100
Answer:
yes he will pay 26.75
Step-by-step explanation:
25×.07=1.75 25+1.75=26 75
Suppose you had f=6, g=2, h=3 and you were asked to find
f - g - h
You would do it by substituting the given values for the letters to get
6 - 2 - 3
And this can be simplified to
1
_____
The question at hand is basically the same. You are given values of f(x), g(x), h(x) and asked to find their signed sum.
f(x) - g(x) - h(x)
= (3x+5) - (4x²-2) - (x²-3x+1) . . . . substitute the given values
= 3x + 5 - 4x² + 2 - x² + 3x - 1 . . . use the distributive property to eliminate parentheses. A minus sign in front changes the sign of every term inside parentheses.
= x²(-4-1) +x(3+3) +(5+2-1)
= -5x² + 6x + 6 . . . . . . collect terms . . . . matches the first choice
Given that the current salary for Ngozi is $24000 and she earns 3.5% raise yearly, the function that will represent her salary in t years will be:
A=P(1+r)^t
where:
A=future amount
P=principle
r=rate
t=time
thus plugging in the values we shall have:
s(t)=24000(1+3.5/100)^t
s(t)=24000(1.035)^t
thus the answer is:
s(t)=24000(1.035)^t
