1012%: 4.8 L; 32%: 3.2 LStep-by-step explanation:
For mixture problems, I like to use a single variable to represent the quantity of the greatest contributor (greatest cost or greatest concentration). Let that variable be x.
1. In this problem, the amount of the greatest contributor is already fixed, so we'll use x for the amount of walnuts. The cost of the mix is ...
0.80x + 1.25(8) = 1.00(x +8)
2 = 0.2x . . . . . . . . . . . . . . . . . subtract 0.8x+8, simplify
10 = x . . . . . . . . . divide by 0.2
10 pounds of walnuts must be used.
__
2. The amount of acid in the mix is ...
12%(8 -x) +32%(x) = 20%(8)
20%(x) = 8%(8) . . . . . . . . . . . . subtract 12%(8)
x = 8(8)/20 = 3.2 . . . . . . . . . . divide by 20%
8-x = 4.8
3.2 liters of 32% acid must be mixed with 4.8 liters of 12% acid

The general solution for mixture problems that have a greater contributor (G), a lesser contributor (L), and a mix value (M) is ...
g/l = (M -L)/(G -M) . . . . . . ratio of quantities of G and L
In the first problem, this becomes ...
8/l = (1.00 -.80)/(1.25 -1.00) = .2/.25 = 4/5 ⇒ l = 8(5/4) = 10
In the second problem, this becomes ...
g/l = (20-12)/(32-20) = 8/12 = 2/3 ⇒ g = (2/5)(8) = 3.2; l = (3/5)(8) = 4.8
In this case, we recognize that the ratio of 2 parts to 3 parts means that the greater contributor is 2 of 5 total parts.

High-definition televisions have an aspect ratio of 16: 9. The following answer choices are television screen sizes rounded to the nearest inch. Which could be a High-definition television?
Answer:
18.5 in approx
Step-by-step explanation:
Given data
aspect ratio of 16: 9
L= 16in
W= 9 in
We want to find the diagonal of the TV
applying Pythagoras theorem
d^2= l^2+w^2
d^2= 16^2+ 9^2
d^2=256+81
d^2= 337
d= √337
d= 18.35 in
Hence the tv is 18.5 in approx

What is the y-intercept, b, of the additive relationship represented by this table?
Enter your answer as an integer in the box.
b =
x y
1 4
3 6
Answer:
3
Step-by-step explanation:
First step: Find the slope, Using the Formula y2 - y1 / x2 - x1 =
6-4=2 3-1=2 then u divde the y/x 2/2=1 So the slope is 1.
Step 2: Use the Slope- Intercept formula, Y=mx+b so 4 = 1(1)+b so 4 = 1 + b
Step 3: subtract 1 on both sides so 4-1=3 1-1=0 so 3 is the Y-Intercept.

19 3/7 - 12 6/7
Plz show how u got your answer
Answer:
16 4/7
Step-by-step explanation:
First, you cant subtract 3/7 from 6/7 so take 1 from 19, which turns it to 18. And add that one to 3/7 to get 10/7, or just add 7 to your numerator. So now you have 18 10/7 - 12 6/7. so subtract 18 - 12 to get 6, and the subtract 10/7 - 6/7 to get 4/7. You dont actually have to subtract the denominator just the numerators, because the denominatos are the same so you leave them just the way they are. I hope this helps :)

Find the measure of the exterior angle.
Answer: 108 degrees
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the two remote interior angles. (Remote referring to the farthest angles from the exterior angle) 2a = (a+10) + 44. Combine like terms.
2a = a+ 54. Subtract “a” from both sides.
a= 54
You can check for correctness by plugging in 54 for a. 2(54) = (54+ 10) + 44. 108= 108.
(Remember, the exterior angle should equal the sum of the two remote interior angles)
Find the area of this composite figure.
Answer: ≈ 551.71 ft²
All work is shown in the picture.
Answer:
551,7
see in the picture, this composite figure is made up of a rectangle and 2 halves of a circle
=> the area of this composite figure = the area of a rectangle + the area of a circle
+) the area of the rectangle = 15.25 = 375
+) the area of the circle = (15/2)².pi = 56,25pi
=> the area of this figure = 375 + 56,25pi = 551,7

What is the value of x in the equation 3(2x + 8) = 0? (4 points)
−8
8
4
−4
Answer:
your answer is D-4
Step-by-step explanation:
3(2x+8)=0
Step 1: Simplify both sides of the equation.
3(2x+8)=0
(3)(2x)+(3)(8)=0(Distribute)
6x+24=0
Step 2: Subtract 24 from both sides.
6x+24−24=0−24
6x=−24
Step 3: Divide both sides by 6.
6x
6
=
−24

x=−4

Each TTF site bought a new rope bridge for 4,500. TTF will make monthly payments of $350 until the bill is paid. Write an equation for the unpaid balance B after m monthly payments
Answer: 4500 - 350m
Step-by-step explanation:
From the question, we are informed that each TTF site bought a new rope bridge for 4,500 and that TTF will make monthly payments of $350 until the bill is paid.
The equation for the unpaid balance B after m monthly payments will be:
= 4500 - 350m
where me = number of months
For example, if the number of months used is 4 months, the unique balance will be:
= 4500 - 350m
= 4500 - 350(4)
= 4500 - 1200
= 3300

Care este cel mai mic număr dintre 95.999,96.959,99.595 și 99.995 la care cifra unităților de mii este 5
Răspuns:
95.999
Explicație pas cu pas:
Care este cel mai mic număr între 95.999; 96.959; 99.595 și 99.995, unde numărul de mii este 5
95.999 = Nouăzeci și cinci de mii nouă sute nouăzeci și nouă
96.959 = Nouăzeci și șase de mii nouă sute cincizeci și nouă
99595 = Nouăzeci și nouă de mii cinci sute nouăzeci și cinci
99995 = Nouăzeci și nouă de mii, Nouă sute nouăzeci și cinci.
Folosind cunoștințele despre linia numerică:
95.999 <96.959 <99.595 <99.995
