Answer:
x = amount of raisins
y = amount of peanuts
x+y = 5
1.50x+2.50y = 10.50
Step-by-step explanation:
I can't see a table, and im not sure what the question is, but anyways,
you solve this by using elimination or substitution in the system of equations.
Personally, substitution is easier for me so:
x+y = 5
y=5-x
1.50x+2.50(5-x) = 10.50
1.50x+12.50 -2.50x = 10.50
-1x+12.50 = 10.50
-x+12.50-12.50 = 10.50-12.50
-1x = -2
-1x/-1 = -2/-1
x = 2
y =5-x
y=5-2
y=3
Since x was the amount of raisins, and y was the amount of peanuts, we can say that Jeremy used two pounds of raisins and 3 pounds of peanuts to make his 5 pounds of trail mix.
The difference between the interest for first and second year on a sum of money compounded annually is rs 30 if the rate of interest is 5% what was the sum of money deposited
Answer:
$600.00
Step-by-step explanation:
The difference between the interest for first and second year on a sum of money compounded annually is rs 30 if the rate of interest is 5% what was the sum of money deposited
We solve using Compound Interest formula which is given as:
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 per year,
Then, solve the equation for P
P = I / ((1 + r/n)^nt - 1)
P = 30 / ((1 + 0.05/1)^(1×1) - 1)
P = 30 / ((1 + 0.05)^(1) - 1)
P = $600.00

Geometry
Answer:
Step-by-step explanation:
9). Dimensions of the logo = 4 inch by 6 inch
∵ 12 inches = 1 feet
∴ 1 inch = [tex]\frac{1}{12}[/tex] feet
Therefore, dimensions of the logo (in feet) will be,
[tex]\frac{4}{12}[/tex] feet by [tex]\frac{6}{12}[/tex] feet Or [tex]\frac{1}{3}[/tex] feet by [tex]\frac{1}{2}[/tex] feet
Dimensions of the logo which are 6 times larger than the original one.
Dimensions of the advertisement = [tex]\frac{6}{3}[/tex] feet by [tex]\frac{6}{2}[/tex] feet
= 2 feet by 3 feet
Area of the advertisement = 2 × 3
= 6 feet²
10). By the property of similar polygons,
"Corresponding sides of two similar polygons are proportional"
If the dimensions of two similar polygons are 'x' and 'kx'
Ratio of the perimeter of two polygons = [tex]\frac{\text{Perimeter of the image polygon}}{\text{Perimeter of the original polygon}}[/tex] = k
Ratio of area of two similar polygons = [tex]\frac{\text{Area of the image polygon}}{\text{Area of the original polygon}}[/tex] = k²
Ratio of volumes of two similar polygons = [tex]\frac{\text{Volume of the image polygon}}{\text{Volume of the original polygon}}[/tex] = k³

there are 3 method to show that 40 is the sum of two prime. among all the prime , find the difference between the two largest prime
Answer:
the difference is 39? for the answer
Step-by-step explanation:
The question is not exactly worded in such a way that one can tell how it should be answered.
If it means that 40 is the suim of 2 primes done 3 ways then the 3 answers are
17 + 23
37 + 3
11+ 29
So the difference between 37 and 29 = 8
There are no guarantees about this answer. I'm just doing it the way the question reads.

Step-by-step explanation:
Convert r=5/3sinθ−cosθ to rectangular form.
Enter your answer in slope-intercept form by filling in the boxes. Enter values so that fractions are simplified.
Answer:
y = 1/3 x + 5/3
Step-by-step explanation:
For rectangular to polar
x = rcosθ ... 1
y = rsinθ ... 2
Given the expression
r=5/3sinθ−cosθ
Cross multiply
r(3sinθ−cosθ) = 5
Expand
3rsinθ−rcosθ = 5 ..3
Substitute 1 and 2 into 3
3y - x = 5
Write in slope intercept form
3y = x + 5
Divide through by 3;
3y/3 = x/3 + 5/3
y = x/3 + 5/3
y = 1/3 x + 5/3
Hence the expression in slope-intercept form is y = 1/3 x + 5/3

x = [?]
Answer: x = 28
Step-by-step explanation:
3x+10+3x+2=180
6x+12=180
6x=168
x = 28
Answer:
x=28
Step-by-step explanation:
Since both lines going up are parallel, we can label the angle to the left of the angle with the measure of 3x+10 3x+2. These angles are supplementary as they are on different sides of the same line. This means that:
(3x+10)+(3x+2)=180
6x+12=180
6x=168
x=28

Natalie and Warren started swimming laps in the pool at 5:47. Natalie finished swimming her laps 27 minutes later. Warren finished swimming his laps 8 minutes after Natalie. What time did Warren finish his laps?
Answer:
6:22
Step-by-step explanation:
original time minutes when they both started - 47
47+ natalie's time
47+27 =74
minus 60 minutes to account for the hour (6 o'clock)
74-60=14
natalie finished at 6:14
warren finished 8 minutes after natalie's time
14+8=22
the hour did not finish so it will remain at 6
which leaves your final answer for the time that warren finished as 6:22

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction
The number b varies directly with the number a. For example b= 2 when a = -2
-2. Which equation represents this
direct variation between a and b?
Obra
O b = a
Ob-a= 0
Ob(-a) = 0
Answer:
b = -a
Step-by-step explanation:
We know that:
On a number line, the distance between 0 and b is the same distance that between 0 and a (but b and a are in opposite sides of zero).
And we know that, for example, when:
b = 2, a = -2
Remember that the distance between two values is given by:
|n - m|
Then the distance between 0 and b is:
|0 - b|
and the distance between 0 and a is:
|0 - a|
we have:
|-b| = |-a|
|b| = |a|
But the numbers are in opposite sides of the zero, so one must be positive and the other negative, then we can conclude that:
b = -a
or
-b = a
(these are equivalent)
Then the correct option is the first option:
b = -a

y -2 -4 2
Step-by-step explanation:
y=x^2-x-4
when x=-1
y=(-1)^2-(-1)-4
y=1+1-4
y=-2
when x=1
y=(1)^2-(1)-4
y=1-1-4
y=-4
when x=3
y=(3)2-(3)-4
y=9-3-4
y=9-7
y=2

Answer:
426 chickens
Step-by-step explanation:
let the pigs = x
the ducks = 2×x = 2x
the chickens = 3×(2x) = 6x
x +2x +6x = 639
9x=639
x = 639/9 = 71
the chickens = 6x = 6×71 = 426
Answer:
[tex]426\:\mathrm{chickens}[/tex]
Step-by-step explanation:
Since a duck has two legs, a pig has four legs, and a chicken has two legs, we can write the following system of equations:
[tex]\begin{cases}d+p+c=639,\\d=2p,\\c=3d\end{cases}[/tex], where [tex]d[/tex] is the number of ducks on the farm, [tex]c[/tex] is the number of chickens, and [tex]p[/tex] is the number of pigs.
Substituting, we get:
[tex]d+\frac{1}{2}d+3d=639,\\4.5d=639,\\d=\boxed{142}[/tex]
Now substitute [tex]d=142[/tex] into [tex]c=3d[/tex] to get the number of chickens:
[tex]c=3(142)=\boxed{426\:\mathrm{chickens}}[/tex]

Name three deficiency diseases associated with diet and state their causes
Answer:
Iron deficiency, hypoglycemia, and scurvy.
Step-by-step explanation:
Iron deficiency is the lack of iron in the blood, usually caused by blood loss. Because the body doesn't produce iron, people need to consume items with iron to rise up the amount of iron.
Hypoglycemia is the lack of blood sugar (known as glucose), people who are diabetic or drink excessive alcohol can have hypoglycemia. People would have to consume more glucose or take insulin shots to get the amount back to normal.
Scurvy is caused by the lack of Vitamin C (found in fruits and vegetables) , usually within 3 months.
what is f(0) for the function f(x) =2x+3
