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.

Pls help me solve 10k - 90 =m -10 *

Answers

Answer:

M = 10k - 80 and k = m/10 + 80

Step-by-step explanation:

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

Step-by-step explanation:

1. Area of the triangle plus the area of the semicircle.

2. Triangle: b x h x .5 14 x 10 x .5= 70

3. area of semicircle: (πr^2).5 7^2 x π x .5 = 76.93

We halved the area of a circle since we have half a circle.

A train is traveling at a constant speed in miles per hour. Hours (x) Miles (y) Which equation models the data in the table? 1 20 2 100 O y=20x 3 180 O y = x + 80 4 260 5 340 Oy=60x – 80 O y = = 80x — 60​

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.

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°.

Whoever answers these thanks!

Answers

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

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

The diagonal of a suitcase measures 30 inches and the height is 18 inches. What is the width of the suitcase to the
nearest Inch?

Answers

Answer:

Step-by-step explanation:

By the Pythagorean Theorem we know

h^2=x^2+y^2 (where h is the hypotenuse and x and y are sides of a right triangle)

w^2+18^2=30^2

w^2=30^2-18^2

w^2=900-324

w^2=576

w=24 in

In the Pythagorean Theorem, a^2+b^2=c^2. The measurements provided here are 30, and 18. 30 is c and 18 is either a or b (it doesn’t matter) 30 is c because it is specified as a diagonal. In reverse to the Theorem, it would be 30^2-18^2= a^2 that would be 900-324. You would then square root what you got for “a” to find your answer. It would be 24.
