-3.39 is your answer
Step-by-step explanation:
Which values are greater than -2
Answer:
what are the choices
Step-by-step explanation:
Plug in the point (1,6) into the inequality 4x-3y<12 to determine if the point is in the solution set. How do you know
A Yes, (1,6) is in the solution set because the truth value is TRUE
B No, (1,6) is not the solution because the truth value is FALSE
Answer:
false
Step-by-step explanation:
4(1) - 3(6)<12
4 - 18<12
12<12
so no the truth value is false 12 is not less than 12
Answer:
A. true
Step-by-step explanation:
If you plug in x and y, the equation is 4(1)-3(6)<12. SImplify to get 4-18<12 which is equal to -14<12 which is true.
Find the x-intercept and y-intercept of the line.
- 8x+ 5y = 18

Hakim received some gift cards for music and movie downloads for his birthday. Using one of them, he downloaded 20 songs and 13 movies, which cost a total of $163. Using another, he purchased 13 songs and 13 movies, which cost a total of $156. How much does each download cost?
Downloads cost $____for a song and $______ for a movie.
Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie

Answer:
y +2 = (1/4)(x +1)
Step-by-step explanation:
The given line is in slope-intercept form:
y = mx + b
where the slope (m) is -4 and the y-intercept (b) is +13.
For the perpendicular line, we need a slope that is the opposite reciprocal, or ...
-1/m = -1/(-4) = 1/4
A suitable form for the desired equation is the point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...
y +2 = (1/4)(x +1)

28inch^2
Step-by-step solution:Rectangle:
[Length x Breadth]
5 + 3 = 8inch
8 x 2.5 = 20inch^2
Right Triangle:
[1/2 x Base x Height]
1/2 x 5 x 2 = 1/2 x 10
= 5inch^2
Left Triangle:
[1/2 x Base x Height]
1/2 x 3 x 2 = 1/2 x 6
= 3inch^2
20 + 5 + 3 = 28inch^2

Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!

Carin has 2/3 of a bottle of paint. She uses 1/6 of a bottle to paint one model airplane. How many model airplanes can carin paint with 2/3 of a bottle of paint. Answer
Answer:
4
Step-by-step explanation:
Given that :
Total fraction of paint Carin has = 2/3 bottle
Fraction used to paint a model airplane = 1/6
Number of model. Airplanes 2/3 of a bottle could paint ;
Total fraction of paint / fraction used to paint a model airplane
(2/3) ÷ (1/6)
2/3 * 6/1
= 12 / 3
= 4 model airplanes

How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-lifeIn this case,
a = 904 is the starting amountH = 60 is the number of days until another half-life occursWhen x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.
