Express the ratio 7day to 6weeks as a decimal fraction<br>

Whitepunk [10]

Answer:

6 weeks=6*7 days=42days

7/42 =1/6 =0.16667

OR

7 days=1 week

therefore 1/6=0.16667

Note that both must be in the same unit.

Why do non STEM majors detest taking algebraic courses at the collegiate level?

yKpoI14uk [10]

Answer:

Because they find it hard to pass in the past.

Step-by-step explanation:

Non-STEM majors detest taking algebraic courses at the collegiate level because based on their past experiences in high school, whereby they probably do not excel in algebra, numbers, or mathematical subjects in general, the thought of going through advanced numbers and equations can be overwhelming.

Nobody wants to have or at least start college with poor grades. Hence, because non-STEM students find algebraic courses hard to pass in the past, they detest taking the course that has to do with it at the college level.

A youth group has a yard sale to raise money for a charity. The group earns $800 but decides to put its money in the

marysya [2.9K]

Answer:

see explanation below

Step-by-step explanation:

In this case, I don't know if the 4% rate is annual, so I'm going to assume that it's annual.

The other thing that I will assume is that this increase is constant but every year you get 4% interest of the amount that you have by the end of the year, and not 4% of the initial amount. However, I will do it by the two methods just in case.

If the amount is increased 4% every year then:

P = Po * (IV)^n

where n: year

To get the index variation (IV):

IV = 4/100 = 0.04, and we also know that every year is increased so:

1 + 0.04 = 1.04

Now let's get the money after 3 years:

P = 800 * (1.04)^3 = 899.89 $ or simply 900$

If the amount is increased 4% but over the initial amount always:

let's calculate the 4% of 800:

800 * 0.04 = 32

The first year it would be:

800 + 32 = 832 $

second year:

832 + 32 = 864$

third year: 864 + 32 = 896$

So, for the first assumption we get 900$ and the second assumption we get 896$.

Please help me with question number 2

Mice21 [21]

Answer:

2. The area of the side walk is approximately 217 m²

3. The distance away from the sprinkler the water can spread is approximately 11 feet

4. The area of the rug is 49.6

Step-by-step explanation:

2. The dimensions of the flower bed and the sidewalks are;

The diameter of the flower bed = 20 meters

The width of the circular side walk, x = 3 meters

Therefore, the diameter of the outer edge of the side walk, D, is given as follows

D = d + 2·x (The width of the side walk is applied to both side of the circular diameter)

∴ D = 20 + 2×3 = 26

The area of the side walk = The area of the sidewalk and the side walk = The area of the flower bed

∴ The area of the side walk, A = π·D²/4 - π·d²/4

∴ A = 3.14 × 26²/4 - 3.14 × 20²/4 = 216.66

By rounding to the nearest whole number, the area of the side walk, A ≈ 217 m²

3. Given that the area formed by the circular pattern, A = 379.94 ft.², we have;

Area of a circle = π·r²

∴ Where 'r' represents how far it can spread, we have;

π·r² = 379.94

r = √(379.94 ft.²/π) ≈ 10.997211 ft.

Therefore, the distance away from the sprinkler the water can spread, r ≈ 11 feet

4. The circumference of the rug = 24.8 meters

The circumference of a circle, C = 2·π·r

Where;

r = The radius of the circle

π = 3.1

∴ For the rug of radius 'r', C = 2·π·r = 24.8

r = 24.8/(2·π) = 12.4/π = 12.4/3.1 = 4

The area = π·r²

∴ The area of the rug = 3.1 × 4² = 49.6.
