Leslie purchased a new bar of soap. Three days after she originally used
the soap, she was curious how much soap per day she was using. She
decide to weigh her soap and that the bar was 103 grams. Four day later
she re-measured the same bar of sop and record a weight of 80 grams.
Assuming that Leslie uses the same amount of soap daily (and that she
used soap daily), write an equation that shows that amount of soap
remaining after d days of use. *Hint: slope intercept form and you will
need the slope formula

Answers

Answer 1

Answer:

The equation is:

y= 103 --23d

Step-by-step explanation:

The initial amount was 103 grams.

After one day of use the remaining amount of soap was 80 grams.

So the amount of time he spent in one day was:

Each day Leslie spends 23 grams of soap.

if d represents the number of days elapsed then, the amount of soap "y" that Leslie spends after days is:

y= 103 --23d

The measure of an exterior angle of a triangle is 40°. What is the sum of the measures of the corresponding remote interior angles?​

Answers

Answer:

40 degrees

Step-by-step explanation:

Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40.

If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.

What are Triangle theories?A triangle is the smallest polygon with three sides and three interior angles.Theorem 1: The Sum of Angles property of a triangle states that the sum of the interior angles of a triangle is 180°.Theorem 2: If you lengthen one side of a triangle, the resulting exterior angle is the sum of the two opposite interior angles of the triangle.A exterior angle equals the sum of his two other angles in the triangle, so the sum of the angles in the triangle is 180 degrees. In other words, the other two angles of the triangle (which together make up the exterior angle) must be combined with the third angle to make a 180 degree angle.

40 degrees is the sum of the measures of the corresponding remote interior angles.

Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.

The diagonals of a rectangle have length 12 and intersect in a 40 degree angle. Find the length and width rounded to the nearest tenth.

Answers

Answer:

Length is 7.7 and width is 9.2

Step-by-step explanation:

The length and width of the rectangle will be the y and x coordinate of the diagonal line at angle of 40 degrees

Length L = dsin theta

Width W = d coos theta

d is the length of the diagonal

Given

d  = 12

theta = 40°

Substitute

Length = 12sin40°

Length = 12(0.6428)

Length = 7.7135

Length ≈ 7.7

Width = 12cos 40

Width = 12(0.7660)

Width = 9.192

Width = 9.2

Hence the length is 7.7 and width is 9.2

Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana's account can be
represented by the equation y = 25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph
represent in this situation?

Answers

Hi there! x would be 6 weeks..

Explanation:

So here says that Jana earns $25 per week for mowing the lawn. But in “x” weeks, she earns $125...this means that you would have to divide 125 with 25 or 25 multiply by x to find the answer of x.

How much does 25 go to 100? Well it would be 5. So for $100 it would be 5 weeks. We also know that 25 is 1 week. So add 5 with 1. 5 plus 1 would be 6.

Therefore, for $125, Jana would have to work for 6 whole weeks.

The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]

Step-by-step explanation:

Cosine is is calculated as adjacent over hypotenuse.  The line adjacent to A  is 3 in length.

So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator

[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

Step-by-step explanation:

Let the present age of sarita be x

Sarita father age = 49years

If  his father age is 4 years more than three times Sarita age, this is expressed as;

49  = 3x + 4

Sind x

3x = 49-4

In a right angle triangle,

In the given triangle,

[tex]\tan (30^\circ) = \dfrac{x}{7}[/tex]

[tex]\dfrac{1}{\sqrt{3}}=\dfrac{x}{7}[/tex]

Answers

Given :

Rochelle is competing in a marathon.

She knows that once she runs 14.7 km she will have completed 35% of the marathon.

To Find :

Total length of the marathon.

Solution :

Let, total distance of the marathon is x km.

So, 35% of x is 14.7 .

In mathematics :

[tex]14.7 = x\times \dfrac{35}{100}\\\\x = \dfrac{14.7\times 100}{35}\\\\x = 42\ km[/tex]

Therefore, total length of the marathon is 42 km.

Answer:

b.(7,30)

e.(20,20)

Step-by-step explanation:

We are given that

x=Width of garden

y=Length of garden

According to question

[tex]x\geq 5[/tex]

[tex]y\geq 20[/tex]

Perimeter of rectangle=[tex]2(x+y)[/tex]

Where x=Width  of rectangle

y=Length of rectangle

Fencing used =[tex]2(x+y)[/tex]

[tex]2(x+y)\leq 80[/tex]

First we change inequality  into equality

[tex]x=5[/tex]...(1)

[tex]y=20[/tex]...(2)

[tex]2(x+y)=80[/tex]

[tex]x+y=40[/tex]...(3)

Substitute x=0 in equation (3)

[tex]y=40[/tex]

Substitute y=0  in equation (3)

[tex]x=40[/tex]

Substitute x=0 and y=0 in equation (3)

[tex]2(x+y)\leq 80[/tex]

[tex]0\leq 80[/tex]

It is true. Therefore, the  shaded region below the line.

[tex]0\geq 5[/tex]

[tex]0\geq 20[/tex]

These are false equation .Therefore, the shaded region above the line.

Substitute x=5 in equation (3)

[tex]5+y=40[/tex]

[tex]y=40-5=35[/tex]

Substitute y=20 in equation (3)

[tex]x+20=40[/tex]

[tex]x=40-20=20[/tex]

Intersection point of equation (1) and (3) is (5,35) and intersect point of equation (2) and (3) is (20,20).

Now,

a.(10,23)

Substitute in

[tex]2(x+y)\leq 80[/tex]

[tex]2(10+23)\leq 80[/tex]

[tex]66\geq 80[/tex]

10>5 and 23>20

it satisfied all inequality.

Hence, it is a solution.

b.(7,30)

7>5

30>20

[tex]2(7+30)=74<80[/tex]

it satisfied all inequality.

Hence, it is a solution.

c.(18,25)

18>5

25>20

[tex]2(18+25)=86>80[/tex]

It does not satisfied third inequality

Hence, it is not a solution.

d.(8,35)

8>5

35>20

[tex]2(8+35)=86>80[/tex]

It does not satisfied third inequality

Hence, it is not a solution.

e.(20,20)

[tex]2(20+20)=80[/tex]

20>5

20=20

it satisfied all inequality.

Hence, it is a solution.
