The distance covered by the snail in 4 minutes is 10 cm.
The speed of snail is,
[tex]\begin{gathered} Spe\text{ed=}\frac{dis\tan ce}{time} \\ =\frac{10}{4}\frac{cm}{\min } \\ =2.5\text{ cm/min} \end{gathered}[/tex]The distance covered by snail in 6 minute is,
[tex]\begin{gathered} \text{Distance}=\text{speed }\times time \\ =2.5\times6 \\ =15\text{ cm} \end{gathered}[/tex]Hence, the distance covered by the snail is 15 cm.
Speed :
Speed is defined as the rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling.
Hence , speed can be calculated by using the formula,
Speed = [tex]\frac{Distance-travelled}{Time-taken}[/tex]
Given data :
Distance travelled by the snail = 10 cm = 0.1 m
Time taken by the snail to travel a distance of 10 cm = 4 min = 240 s
Then , speed of the snail = [tex]\frac{10}{4}[/tex] = 2.5 cm/min = 0.0004 m/s
If the time taken by the snail is 6 min = 360 s
Then, the distance travelled by the snail in 6 min
= speed x time taken
= 2.5 cm/min x 6 min
= 15 cm = 0.15 m.
Therefore, the snail travels a distance of 15 cm in 6 min.

A plant s 6.2cm tall.
The height of the plant increases by 11% each week
Find how tall the plant will be after 2 weeks
The height of plant will be 7.56cm tall after 2 weeks
How to calculate the height of the plant ?The original height of the plant is 6.2cm
The height increases by 11% each week
= 11/100
= 0.11
The increase of the plant in a week
= 0.11 × 6.2
= 0.682
The height of the plant after two weeks can be calculated as follows
= 0.682 + 0.682
= 1.364
= 6.2 + 1.364
= 7.56
Hence the height of the plant after 2 weeks is 7.56cm

Ms. Wilson invested $30,000 in two accounts, one yielding 8% interest and the
other yielding 9%. If she received a total of $2,590 in interest at the end of the
year, how much did she invest in each account?
The amount invested at 8% was $
The amount invested at 9% was $
Answer:
The amount invested at 8% was $11,000
The amount invested at 9% was $19,000
Step-by-step explanation:
Let the variable x represent the amount in $ invested at 8% and let y be the amount in $ invested at 9%
Total amount invested:
x + y = 30000 [1]
8% = 8/100 = 0.08
9% = 9/100 = 0.09
Interest at 8% on $x = 0.08x
Interest at 9% on $x = 0.09x
Total Interest :
0.08x + 0.09y = 2590 [2]
Using equations [1] and [2] we can solve for x and y
We have
x + y = 30000 [1]
0.08x + 0.09y = 2590 [2]
Multiply equation 1 by 0.08 to get
0.08x + 0.08y = 0.08(30,000)
0.08x + 0.08y = 2,400 [3]
Subtract [3] from [2] :
0.08x + 0.09y = 2590
-
0.08x + 0.08y = 2400
----------------------------------
0x + 0.01y = 190
Divide both sides by 0.01
0.01y/0.01 = 190/0.01
y = = 19,000
Use [1] to get value of x
x + y = 30,000
x + 19,000 = 30,000
x = 30,000 - 19,000
x = 11,000

write the slope intercept form:through: (4, -5), perp. to x= -4
The line should be perpendicular to x = -4
x= -4 is a vertical line crossing the x axis at x= -4
The slope is undefined in x =-4
For an equation in slope intercept form, the general form is ;
y= mx + b where m is the slope and b is the y-intercept
So for any y value, x is always -4
Thus the slope for line x = -4 is not defined
A line perpendicular to x = -4 will thus be a horizontal line with slope 0

Your boss would like you to try to increase that amount to $60,000.00. How much of an increase does the new amount represent over the previous amount?
Based on the amount you have received in grants, and the amount the boss wants to increase it to, the increase the new amount represents over the previous amount is $15,000 or 33.3%.
How to find the increase?Your boss wants to increase the grants to $60,000 from the current amount of $45,000.
This means that the new amount will represent an increase over the previous amount by:
= 60,000 - 45,000
= $15,000
In percentage terms this is:
= Increase over previous amount / Previous amount x 100%
= 15,000 / 45,000 x 100%
= 33.3%
