Evan jarred 10 liters of jam after 2 days. How many days does Evan need to spend making jam if he wants to jar 15 liters of jam in all? Assume the relationship is directly proportional.
Answers
Find liters per day by dividing the amount made by the number of days :
10 liters / 2 days = 5 liters per day.
Find how much more he needs to make by subtracting the amount made from the total he wants:
15 liters - 10 liters = 5 liters more needed.
Divide amount needed by time:
5/5 = 1
He will need to spend 1 more day, which means he will spend a total of 3 days to make 15 liters.

Given f(x) = 2x ^ 2 + kx - 20 and the remainder when f(x) is divided by x - 10 is 90, then what is the value of k?
Answers
Answer:
k = -9
Step-by-step explanation:
f(x) = 2x²+kx-20
From remainder theorem,
x = 10 and f(10) = 90
f(10) = 90
Subsitute the value of x into the expression above.
f(10) = 2(10²)+10k-20 = 90
200+10k-20 = 90
Solve for k by collecting like terms
10 k = 90+20-200
10k = 110-200
10k = -90
k = -90/10
k = -9.
Hence the value of the constant is -9

In Triangle JKL, K is 3 times the measure of J, and L is 8 times the measure of J. Find the measure of each angle in Triangle JKL.
Answers
Answer: The measure of angle J = 15°, measure of angle K =45° and the measure of angle J = 120°.
Step-by-step explanation:
Let the measure of angle J be x.
Then, the measure of angle K will be 3x
and the measure of angle L = 8x
Since the sum of all angles of a triangle is 180 degrees.
Then,
angle J + angle K + angle L = 180 degrees
⇒ x+3x+8x =180
⇒ 12x = 180
⇒x = 15 [divide both sides by 12]
Hence, the measure of angle J = 15°, measure of angle K = 3(15) =45° and the measure of angle J = 8 (15) = 120°.
i.e. the measure of angle J = 15°, measure of angle K =45° and the measure of angle J = 120°.

The sum of two numbers is 51. The smaller number is 17 less than the larger number. What are the numbers?
Larger number
smaller number
Answers
Answer:
smaller number = 17, larger number = 34
Step-by-step explanation:
Let x be the smaller number and y be the larger nuber
x + y = 51 --(1)
y - 17 = x --(2)
Sub (2) into (1)
y - 17 + y = 51
y = 34
Put y = 34 into (2)
34 - 17 = x
x = 17
Ans: smaller number = 17, larger number = 34
Answer:
Let get large number is x and small number as y.
sum of two numbers is 51.(small number + large number = 51)
ie. x +y =51 --------(1)
The smaller number is 17 less than the larger number.
x-y = 17 ------------(2)
(1) +(2);
(x + y ) + (x - y) = 51 +17
2x = 68
x=34
Substituted for (1);
x + y =51
34 + y =51
y= 51 -34
y= 17

Answers
Given:
A train is traveling at a constant speed in miles per hour.
The table of value is:
Hours (x) Miles (y)
1 20
2 100
3 180
4 260
5 340
To find:
The equation for the given data table.
Solution:
It is given that the train is traveling at a constant speed in miles per hour. So, it is a linear relationship.
Choose any two point from the given table of value. Let the two points are (1,20) and (2,100). So, the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-20=\dfrac{100-20}{2-1}(x-1)[/tex]
[tex]y-20=\dfrac{80}{1}(x-1)[/tex]
[tex]y-20=80(x-1)[/tex]
Add 20 on both sides.
[tex]y=80(x-1)+20[/tex]
[tex]y=80x-80+20[/tex]
[tex]y=80x-60[/tex]
Therefore, the correct option is D.

Answers
Answer:
Step-by-step explanation:
Area = L x W gym area is (5x + 5x) ft² if W = 5x Find the L
Area = L x W divide both sides by W
Area/W = (L x W) / W
Area/W = L = Area/W
L = Area/W
= (5x + 5x) / (5x)
= 5x( 1 + 1) / 5x
= 5x(2) / 5x the 5x's cancel each other 5x/5x = 1

Answer:
1) increasing the side by a quantity of 1 causes the new square to increase by 2 times the previous side quantity + 1.
Example 1: 3x3=9, if you increase the sides to 4x4 increases the square by (2x3+1) to be 16.
Example 2: 12x12=144, if you increase the sides to 13x13 increases the square by (2x12=1) to be 169.
2) The same relationship
Step-by-step explanation:
1)
3 x 3 = 9
4 x 4 = 16
5 x 5 = 25
2)
5 x 5 = 25
12 x 12 = 144
13 x 13 = 169
