if a scientist is able to use 4 kilograms of fertilizer for 5 weeks how much fertilizer did they use each week

First, we have to add them all together to get the total amount of markers.

2 + 1 + 3 + 2 + 2 = 10

Red: 3/10

Yellow: 2/9

3/10 x 2/9 = 6/90

Simplify: 6/90 = 1/15

C. 1/15 would be your answer.

Hope this helps! Have a great day!

Answer:

1. 3x + 2  - First degree

2. 4x3 + 17x - 5  - Third degree

3. 13x" + 5xn-2  - Second degree

4. 0.55x2 + 0.7x  - Second degree

5. 7x3 + 10x + 15  - Third degree

Step-by-step explanation:

The degree of a polynomial is given by the highest power of the given variable (x in this case) in the polynomial. All the elements are considered in selecting the highest power of x in the polynomials.

Considering all; the highest degree of x in the polynomials given is 3 while the lowest is 1 hence we have polynomials ranging from the first to third degrees.

Answer:

2 > x

Step-by-step explanation:

-2x + 6 > 3x - 4

10 >5x

Divide each side by 5

10/5 > 5x/5

2 > x

Answer:

x < 2

Step-by-step explanation:

-2x + 6 > 3x - 4

6 + 4 > 3x + 2x

10 > 5x

2 > x

x < 2

Answer:

The ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3

Step-by-step explanation:

The height of a right circular cylinder is 1.5 times the radius of the base.

Let the radius of base be x

So, Height of a right circular cylinder = 1.5x

Total surface area of cylinder =[tex]2 \pi r h + 2 \pi r^2 = 2 \pi r(h+r)=2 \pi \times x(x+1.5x)=2 \pi \times x \times 2.5x[/tex]

Curved surface area of cylinder = [tex]2 \pi rh = 2 \pi \times x \times 1.5 x[/tex]

So, Ratio of the total surface area to the lateral (curved) surface area of the cylinder = [tex]\frac{2 \pi \times x \times 2.5x}{2 \pi \times x \times 1.5 x}=\frac{2.5}{1.5}=\frac{25}{15}=\frac{5}{3}[/tex]

Hence the ratio of the total surface area to the lateral (curved) surface area of the cylinder is 5:3

Answer: 15 yards

Step-by-step explanation:

From the question, we have been informed that the Steelers are on the Cowboys' fifteen-yard line. Using the place value mat to calculate how much farther Steelers need to travel to score a touchdown goes thus:

Since the play is 15 yards from the Cowboys end-zone, therefore Steelers need to travel 15 yards for them score a touchdown.

Final answer:

The Steelers are 85 yards away from the end zone.

Explanation:

To calculate how much farther the Steelers need to travel to score a touchdown, we need to know the distance from the Cowboys' fifteen-yard line to the end zone. The distance between each yard line on a football field is 10 yards. Since the Steelers are on the fifteen-yard line, they are 85 yards away from the end zone (100 yards - 15 yards = 85 yards).

Answer:

7.4cm

Step-by-step explanation:

diameter =2radius

=2×4.7

=7.4cm

The diameter of circle A with a radius of 4.7 cm is 9.4 cm.

To find the diameter of a circle, you can use the formula: diameter = 2 * radius. Given that circle A has a radius of 4.7 cm, the diameter would be 2 * 4.7 = 9.4 cm.

Answer:

They will have $1651 after two years.

Step-by-step explanation:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.

$1500 dollars into an account at an annual rate of 4.8%

This means that [tex]P = 1500, r = 0.048[/tex]

Interest compounded twice a month.

A year has 12 months.

So 12*2 = 24 compundings, which means that [tex]n = 24[/tex]

How much will they have after two years?

This is A(2).

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(2) = 1500(1 + \frac{0.048}{24})^{24*2} = 1651[/tex]

They will have $1651 after two years.

Answer:

d ≤ 95

Step-by-step explanation:

The inequality that states we have at most 95 days is d≤ 95.

A connection between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.

The inequality can be resolved by adding the same amount to each side, subtracting the same amount from each side, multiplying or dividing each side by the same positive integer, and more. If you multiply or divide either side by a negative value, you must flip the inequality sign.

If d represents how many days are left in school this year.

And we have at most 95 days.

Then,

d can not be more than 95.

d ≤ 95

Therefore, the inequality is d ≤ 95.

#SPJ2

Answer:

$47,000

Step-by-step explanation:

Let u represent the unknown amount of budget

10/100× u = $5000

10u/100=$5000

Cross multiply both sides

10u= $500000

Divide both sides by the coefficient of u

10u/10=$500000/10

u= $50000

Therefore, this year's budget is $50000

Since Smith's budget this year is $3000 greater than last year's budget, to find last year's budget we simply subtract the difference from this year's budget.

$50000- $3000

= $47000

Thus, Smith's total budget for last year was $47000.

Answer: $47,000

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

Their total budget this year is $3,000 more than last year, so we have to add 3000 to their total budged of last year (x). x+3000

Since they spend 10% of their budget on entertainment, we have to multiply the previous expression by the percentage in decimal form (divided by 100).

(x +3000) 10/100 = (x+3000) 0.1

Finally, that expression must be equal to the amount that they will spend in entertainment this year (5000).

(x + 3000) 0.1 =5000

Solving for x:

x+3000 = 5000/0.1

x +3000= 50,000

x = 50,000-3,000

x = $47,000

Answer:

B is your answer

Step-by-step explanation:

Final answer:

The correct comparison is that 4.06 is less than 4.6 because when looking at the decimal parts, '0.6' (4.6) is greater than '0.06' (4.06).

Explanation:

To compare the numbers 4.06 and 4.6, we need to look at the decimal parts, since the whole number part (4) is the same for both. In the number 4.06, the decimal part is '06', which is actually '0.06' when read as a fraction of the whole number. On the other hand, 4.6 has a decimal part of '6', which is '0.6' as a fraction of the whole number. When comparing '0.6' and '0.06', it is clear that '0.6' is larger because '6' tenths is greater than '6' hundredths.

Therefore, the correct comparison between 4.06 and 4.6 is 4.06 < 4.6, which corresponds to option D in the question.

Answer:

The vertex of the function is at (–3,–16)

The graph is increasing on the interval x > –3

The graph is positive only on the intervals where x < –7 and where x > 1

Step-by-step explanation:

The roots of this function are the values that make f(x) = 0. As the equation is already factored, we can see that the roots are x1 = 1 and x2 = -7

The x-coordinate of the vertix can be calculated as:

x_v = (x1 + x2)/2 = -6/2 = -3

So the first statement: "The vertex of the function is at (–4,–15)" is wrong.

The y_coordinate of the vertex is:

f(x_v) = (x_v - 1)*(x_v + 7) = (-3 -1) * (-3 +7) = (-4) * (4) = -16

So the second statemente: "The vertex of the function is at (–3,–16)" is correct.

for values of x greater than x_v = -3, the graph increases, as the equation represents a parabola with concavity upwards. So the third statement is correct.

As the roots are 1 and -7 and the concavity is upwards, the parabola have positive values for x<-7 and x>1. So the fourth statement is correct.

For values of x< -4, the parabola can have both positive or negative values (it has positive values for x < -7) so the fifth statement is wrong.

Answer:

B. The vertex of the function is at (–3,–16).

C. The graph is increasing on the interval x > –3.

D. The graph is positive only on the intervals where x < –7 and where

x > 1.
