A distrubutor wants to make 1,000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?
Answer:
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Step-by-step explanation:
System of Equations
Let's call
x = pounds of trail mix 5% raisins
y = pounds of trail mix 20% raisins
The distributor wants to make 1,000 pounds of trail mix, thus:
x + y = 1,000 [1]
The mix must be 8% raisings as a combination of x and y, thus:
5x + 20y = 8*1,000 = 8,000
Dividing by 5:
x + 4y = 1,600 [2]
Subtracting [2] and [1]:
4y - y = 1,600 - 1,000
Operating:
3y = 600
y = 200
From [1]
x = 1,000 - y = 1,000 - 200
x = 800
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Answer:
5% raisin mix: 800 lbs
20% raisin mix: 200 lbs
Step-by-step explanation:
Let number of 5% be x; and number of 20% be a.
x + y = 1000
5% · x + 20% · y = 8% of 1000 pounds
0.05x + 0.2y = 80
x = 1000 - y
0.05(1000 - y) + 0.2y = 80
50 - 0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
x = 1000 - 200
x = 800

SLOPE HELP
hey, this just help if you're confused about slopes because I've seen a few questions about them I'll clear up a few things!
slope formula is y2-y1/x2-x1
memorize that and you'll be able to find your slope!
if you're given 2 points please label them (3,4) (0,6) labeling is this >>> (x1 3, y1, 4)
(x2 0, y2 6)
this makes it so it's organized and you know what you're subtracting
trust me I'll try to do it in my head and calculate it with a calculator then forget what points I used so WRITE IT DOWN! lol
if you hear parallel it's the same slope!
if you hear perpendicular it's the negative reciprocal example: 3/4x the perpendicular slope would be -4/3x
if you have a point and a slope and a line plugin the point to your line! let's say this one is parallel so the same slope
(3,4) y=3/4x + 2
4=3/4(3)+b
and solve for b!
anyways hopes this helps-

Answer:
What is the constant variation of Y =- 2 3x?
The constant of variation, k , is 23 .
Step-by-step explanation:
When x is zero in a direct variation equation y will also be zero. That means that the y-intercept of all direct variation equations is always zero.

A line passes through the points(4,10) and (9,20) Write a linear function in terms of X and Y for this line
Answer:
y = 2x + 2
Step-by-step explanation:
given : line passes through the points (4,10) and (9,20)
Required : write a linear function in terms of x and y
solution :
substitute the coordinate points into the equation: y = mx + b
(x=9, y=20) _ 20 = 9m + b
(x=4, y=10) 10 = 4m + b
subtracting 10 = 5m
m = 10/5
m = 2
substitute x=2 back into eq.1 to solve for b
20 = 9m + b
20 = 9(2) + b
20 - 18 = b
b = 2
therefore the straight line equation is:
y = mx + b
y = 2x + 2
If a polygon is a square, then a polygon is a quadrilateral The truth value: The converse: The truth value: The inverse: The truth value: The contrapositive: The truth value:
Answer and Step-by-step explanation:
Given that if a polygon is a square, then a polygon is a quadrilateral, we find the converse, inverse and contrapositive of this implicational statement. The hypothesis is the causative statement and the conclusion is the resultant effect
The converse of this statement is the reverse of its statements hence:
If a polygon is a quadrilateral then a polygon is a square
The inverse of this statement is the negation of the statements hence :
If a polygon is not a square then a polygon is not a quadrilateral
The contrapositive of the statement is the interchange of the hypothesis and conclusion of the inverse statement hence:
If a polygon is not a quadrilateral then a polygon is not a square

A 350-gallon pool is being drained at a rate of 2 gallons per minute. What is the domain of the function that represents the volume of water in the pool after x minutes?
A. 0 ≤ x ≤ 25
B. 0 ≤ x ≤ 175
C. 0 < x < 350
D. 0 < x < 400
The required domain of the function that represents the volume of water in the pool after x minutes is 0 < x < 350.
Given that,
A 350-gallon pool is being drained at a rate of 2 gallons per minute, what is the domain of the function that represents the volume of water in the pool after x minute is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
since the volume of the pool when it was full of water is 350 gallons,
so the domain of the water present in the pool will be from 0 gallons of water to 350 gallons of water. But water gets drained at the rate of 2 gallons per minute, so the water present must be less than 350 in the first second. The domain of water remaining in the pool will be 0 < x < 350.
Thus, The required domain of the function that represents the volume of water in the pool after x minutes is 0 < x < 350.

3x=10 how do you solve this, i hate math and dont know what to do. help?
Answer:
x = 10/3
Step-by-step explanation:
Okie so to solve a one variable equation, we have to isolate x. To do that, we have to divide both sides of the equation by 3 so we get x = 10/3.
