Given :
After 4 days, a plant is measured to be 10 inches tall.
Later, after a total of 20 days, then height is measured to be 18 inches.
To Find :
The rate of growth for the plant.
Solution :
We know, rate is given by :
[tex]Rat e=\dfrac{\text{Change in height}}{\text{Time taken}}\\\\Rate = \dfrac{18-10}{20-4}\\\\Rate = 0.5 \ inch/day[/tex]
Therefore, rate of increase of height is 0.5 inch/day .
Hence, this is the required solution.

1)450
2)4500
3)45000
Answer:
(2)
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = area of base × height
= 300 × 15
= 4500 cm³
Find the area of a circle that has a circumference of 175.84 inches
with explanation.
Will give brainliest.
Answer:
[tex]{ \boxed{ \bold{ \text{Area \: of \: a \: circle} \: = \tt{2461.76 \: {inches}^{2}}}}} [/tex]
☯ Question :Find the area of a circle that has a circumference of 175.84 inches.☯ Step - by - step explanation :☄ Given :
Circumference of a circle = 175.84 inches☄ To find :
Area of a circle = ?☄ First, we have to find :
Radius of a circle ( r )♨ Finding the radius of a circle :
[tex] \boxed{ \sf{Circumference \: of \: a \: circle = 2\pi \: r}}[/tex]
Substitute the value of circumference of a circle
[tex] \longrightarrow{ \sf{175.84 = 2\pi \: r}}[/tex]
Swap the sides of the equation
⟶ [tex] \sf{2\pi \: r \: = 175.84}[/tex]
Use [tex] \sf{ \pi \: ≈ \: 3.14}[/tex] , we obtain
[tex] \longrightarrow{ \sf{2 \times 3.14 \times r = 175.84}}[/tex]
Multiply : 2 by 3.14
[tex] \longrightarrow{ \sf{6.28 \: r = 175.84}}[/tex]
Divide both sides by 6.28
[tex] \longrightarrow{ \sf{ \frac{6.28 \: r}{6.28} = \frac{175.84}{6.28}}} [/tex]
[tex] \longrightarrow{ \sf{r \: = \: 28 \: inches}}[/tex]
☞ Now , we have :
Radius of a circle ( r ) = 28 inchesFinding the area of a circle having the radius of 28 inches :
[tex] \boxed{ \sf{Area \: of \: a \: circle = \pi \: {r}^{2} }}[/tex]
Substituting the radius , we get :
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = \pi \: {(28)}^{2} }}[/tex]
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = 784 \: \pi}}[/tex]
Using [tex] \sf{\pi \: ≈ \: 3.14}[/tex] , we obtain :
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = 784 \times 3.14 }}[/tex]
[tex] \longrightarrow{ \boxed{ \sf{Area \: of \: a \: circle = 2461.76 \: {inches}^{2} }}}[/tex]
Therefore , area of a circle is 2461.76 inches²
And we're done !
Hope I helped!

A number cube is tossed 50 times, and a 2 is rolled 14 times. Find the experimental probability of not rolling a 2. Enter your answer as a simplified fraction.
Answer:
18/25
Step-by-step explanation:
With regards to the above information, we can infer that since a 2 is rolled 14 times, then 36[50 - 14]rolls are not 2.
The experimental probability would then be;
= 36/50
= 18/25
The experimental probability of not rolling a 2 is 18/25.

There are 36 students in the chess club, 40 students in the drama club, and 24 students in the film club. What is the ratio of students in the drama club to students in the film club?
Answer:
5 to 3 (5:3)
Step-by-step explanation:
drama: 40 film:24
40:24 /2
20:12 /2
10:6 /2
5:3
Answer: 5/3
Step-by-step explanation:
The ratio is 40/24 and to simplify this, you need to divide both sides by the largest number possible while still getting a whole number. You can divide both sides by 8 which will get you 5/3.
The ratio of students in the drama club to students in the film club is 5/3.

This is a vocabulary question. The angles named by the relationships A-E are angles that have the transversal as a common side. "Interior" and "exterior" refers to the space between the crossing lines, or outside the crossing lines, respectively. "Alternate" means the angles are on opposite sides of the transversal; "consecutive" means they are on the same side of the transversal.
Angles are "corresponding" if they are in the same direction from the point of intersection where the transversal crosses the two lines. The angles will be "consecutive", but one will be interior and the other will be exterior.
4. angle 9 is left of q, above r; angle 16 is right of q and below s, so these are alternate exterior angles, C.
__
5. angle 3 is below r and left of p; angle 5 is above s and left of p, so these are consecutive interior angles, D.
__
6. angle 7 is below s and left of p; angle 15 is below s and left of q, so these are corresponding angles, A.
__
7. angle 1 is above r and left of p; angle 10 is above r and right of q, so these are consecutive exterior angles, E.
__
8. angle 2 is above r and right of p; angle 11 is below r and left of q, so these are alternate interior angles, B.
__
9. angles 6 and 13 are above transversal s.

Each box holds 6 black markers and 4 red markers. Derek has 0 boxes of markers. Write a number sentence that shows how many markers Derek has. Explain how you found your answer.
Answer:
0 x 1 x 10 = 0
Step-by-step explanation:
0 x 1 x 10 = 0
This is problem that has to do with multiplication with 0.
Since Derek has 0 boxes of markers and each box contains 10 markers, 6 black and 4 red, think of it as Derek having 0 groups of a box of markers. This means Derek has 0 boxes where each box contains 10markers.
0 boxes means Derek has no markers.

Right triangle LMN is shown. What is the length of the hypotenuse, x, of triangle LMN? Round your answer to three decimal Places. Use the equation below.
Answer:
55.866 ft
Step-by-step explanation:
[tex] c^2 = a^2 + b^2 [/tex]
[tex] x^2 = 40^2 + 39^2 [/tex]
[tex] x^2 = 1600 + 1521 [/tex]
[tex] x^2 = 3121 [/tex]
[tex] x = \sqrt(3121} [/tex]
[tex] x = 55.8659 [/tex\
Answer: 55.866 ft
The length of the hypotenuse, x, of triangle LMN to 3 decimal place is
55.866 ft
using Pythagoras theorem,
c² = a² + b²
where
c = hypotenuse
a and b are the 2 other legs.
Therefore,
40²+ 39² = x²
1600 + 1521 = x²
x² = 3121
square root both sides
x = √3121
x = 55.8659108939
x ≈ 55.866 ft

(a) Write down an expression for the perimeter of the rectangle, giving your
answer in its simplest form.
The perimeter of the rectangle is 62 cm.
(b) Work out the length of the rectangle.
The expression for the perimeter is 4x + 10 = 62 and the length of the rectangle is 18 cm.
What is a perimeter?The perimeter is the distance around the edge of a shape.
Given that the width of the rectangle is x cm, length is x+5, and the perimeter is 62.
The general equation for the perimeter of a rectangle is given by
2 (length + width) = perimeter
By substituting the values we get
2(x+5+x) = 62
i.e 4x+10 = 62
x=52/4 = 13
Then length is given by
x+5 = length
i.e length = 18
Hence the 4x + 10 = 62 is the expression for the perimeter of a rectangle of length 18cm.

4. X varies directly with the square of y, where x>0,
and y >0. If x= 3 when y = 5, then what is the value
ofy when x= 48?
Answer:
The value of y, when x = 48 is y = 12/5
Step-by-step explanation:
The given parameters are;
x is directly proportional to y
Where x > 0, y > 0
For x = 3. y = 5
Therefore, we have;
x ∝ a·y²
For ,x = 3, when y = 5, we have;
3 = a × 5² = 25·a
∴ a = 25/3
When x = 48, we have;
48 = 25/3×y²
y² = 3/25 × 48 = 144/25
y = √(144/25) = 12/5
y = 12/5
The value of y, when x = 48 is y = 12/5.
