Jill is studying a strange bacterium. When she first looks at the bacteria, there are initially.
100 cells in her sample. The next day, there are 300 cells (Day 1). Intrigued, she comes
back the next day to find that there are 900 cells (Day 2)!

Answer:

x = 56, x = 30

Step-by-step explanation:

(a)

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

72 + 2x + 99 + 89 + 3x = 540, that is

5x + 260 = 540 ( subtract 260 from both sides )

5x = 280 ( divide both sides by 5 )

x = 56

----------------------------------------------------------------

(b)

The sum of the exterior angles of a polygon = 360°

sum the exterior angles and equate to 360

94 + 56 + 4.5x + x + 1.5x = 360, that is

7x + 150 = 360 ( subtract 150 from both sides )

7x = 210 ( divide both sides by 7 )

x = 30

Perimeter is the sum of the two lengths plus the sum of the two widths.

Divide the perimeter in half and that is the sum of one length and one width.

27/2  = 13.5

The ratio is 2:1, add the ratio: 2 +1 = 3

Divide the sum by 3:

13.5/3 = 1.5

Multiply that the each portion of the ratio:

4.5 x 2 = 9

4.5 x 1 = 4.5

The length is 9 inches

The width is 4.5 inches

Answer:

Student should show that the solution to the system of equations 7x - y = 4 and 2x - 3y = 1 is the same as the solution to the given system of equations.

Step-by-step explanation:

Given System of equations is 5x + 2y = 3 (equation 1) and 2x - 3y = 1 (equation 2)

Second System of equations is 2x - 3y = 1 and 7x - y = 4

How we got  7x - y = 4

Step 1: Multiply 2x - 3y = 1 by 1, we get the same 2x - 3y = 1

Step 2: Add 5x + 2y = 3 with 2x - 3y = 1

5x + 2x + 2y - 3y = 1

7x - 3y = 1

We have got second equation 7x - 3y = 1

Thus, Student should show that the solution to the system of equations 7x - y = 4 and 2x - 3y = 1 is the same as the solution to the given system of equations.

Answer:

270 cm²

Step-by-step explanation:

The question is not complete, but a similar question is attached.

Solution:

A prism is a three dimensional polygon with two identical and opposite faces. These bases are called the base of the polygon.

A triangular prism is a prism in which its bases are triangular in shape and it also has three rectangular sides.

The total surface area (TSA) of a triangular prism is given by:

TSA = area of triangle 1 + area of triangle 2 + area of rectangle 1 + area of rectangle 2 + area of rectangle 3

Area of triangle 1 = (1/2) * base * height = 1/2 * 6 * 5 = 15 cm²

Area of triangle 2 = (1/2) * base * height = 1/2 * 6 * 5 = 15 cm²

Area of rectangle 1 = length * breadth =15 * 6 = 90 cm²

Area of rectangle 2 = length * breadth =15 * 5 = 75 cm²

Area of rectangle 3 = length * breadth =15 * 5 = 75 cm²

TSA = 15 cm² + 15 cm² + 90 cm² + 75 cm² + 75 cm² = 270 cm²

Answer:

150%

It is a percentage increase

Step-by-step explanation:

We start by calculating the percentage increase

Mathematically, we have this as;

Percentage increase = (new value - old value)/old value * 100%

New value = new height = 60 inches

old value = old height = 24 inches

Substituting these values, we have ;

(60-24)/24 * 100%

= 36/24 * 100%

= 1.5 * 100% = 150%

It is a percentage increase as we can see growth

Answer:

System of equations: 8x + 2y = 82 and 4x + 2y = 54

Step-by-step explanation:

Given that:

8 solo acts and 2 ensemble acts will last for 82 minutes

4 solo acts and 2 ensemble acts will last for 54 minutes

Let,

x be the minutes solo acts lasts

y be the minutes ensemble acts lasts

According to given statement;

8x + 2y = 82

4x + 2y = 54

Hence,

System of equations: 8x + 2y = 82 and 4x + 2y = 54

Answer:

6.5 Hours

Step-by-step explanation:

If it takes Ron 12 hours to go 6.8 miles then 8 hours more is only 1.7 miles an hour. It will take him well over 6.5 hours to do 20 miles so 6.5 hours is the closest answer

The time that should be taken for Ron to travel 20 miles in 3.5 hours.

Given that

Ron traveled 6.8 miles in 1.2 hours.

We need to find out the time that should be taken for Ron to travel 20 miles.

So, the time taken should be

[tex]= \frac{20\ miles \times 1.2\ hours}{6.8\ miles}[/tex]

= 3.5 hours

Here we assume that time should be 1.2 hours instead of 12 hours.

Therefore we can conclude that The time that should be taken for Ron to travel 20 miles in 3.5 hours.

Answer: a= 14 , b= 15, c =15 , d =18 , e= 18.

Step-by-step explanation:

Stratified sample is a sampling technique used to show the participation of each group present in the population..

Person sampled from each group =[tex]\dfrac{Person\ in\ group}{Population}\times sample\ size[/tex]

Total students = 140+150+150+180+180 =800

In sample

Person of Year 7 students = [tex]\dfrac{140}{800}\times80=14[/tex]

Person of Year 8 students = [tex]\dfrac{150}{800}\times80=15[/tex]

Person of Year 9 students = [tex]\dfrac{150}{800}\times80=15[/tex]

Person of Year 10 students = [tex]\dfrac{180}{800}\times80=18[/tex]

Person of Year 11 students = [tex]\dfrac{180}{800}\times80=18[/tex]

Hence, a= 14 , b= 15, c =15 , d =18 , e= 18.

Answer:

44º

Step-by-step explanation:

We are given that a triangle QRS

QR=20 units

RS=24 units

QS=34 units

We have to find the measure of angle Q.

We know that cosine law

[tex]a^2=b^2+c^2-2bc cos A[/tex]

Using the formula

[tex](24)^2=(20)^2+(34)^2-2\times 20\times 34 cos Q[/tex]

[tex]576=1556-1360 cosQ[/tex]

[tex]1360osQ=1556-576[/tex]

[tex]1360 cos Q=980[/tex]

[tex]cos Q=\frac{980}{1360}[/tex]
