Answer:

A≈676.2

Step-by-step explanation:

1. Exponentially solve equation

A=249e-0.0015t as t = 43 years (Unless conversion to seconds)

A≈676.2

2. Solve graphically = intersect = (43, 676.2) x axis is time y axis is amount.

Answer:

w= 40b

w=40× 5

w=200

......

Answer: w = 200

Step-by-step explanation:

40 x 5 is 200

Answer:

no, they are not equivalent. the second expression simplified = 2-1.5t.

1.5-2t and 2-1.5t are not equal.

Answer:

n is 18

Step-by-step explanation:

Answer:

24 - n = 6

Figure out what plus 6 will give you 24.

Or add 24 and 6 and use the sum as the fill-in for n.

24 + 6 = 30.  

Replace the variable.

30 (n) - 24 = 6.

Answer:

its (0, 3) or (3, 0)

Step-by-step explanation:

its not A. or D.

Answer:

[tex](3,0)[/tex]

Step-by-step explanation:

The x-intercept(s) of a function is the point(s) where the function intersects the x-axis, or the horizontal axis. If we look at the graph, we see that the function intersects the x-axis when [tex]x=3[/tex] (we know this because [tex]3[/tex] is directly in between [tex]2[/tex] and [tex]4[/tex]) and [tex]y=0[/tex], so the answer is [tex](3,0)[/tex]. Hope this helps!

Answer:

3rd one

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

The computation is shown below:

In weekend, at least [tex]2 \frac{1}{2}[/tex] hours should be practice i.e. 2.5 hours

But actual he would be practice

[tex]= 1 \frac{1}{6} + 1 \frac{1}{4}\\\\= \frac{7}{6} + \frac{5}{4}\\\\= \frac{14 + 15}{12} \\\\= \frac{29}{12}\\\\= 2.4167[/tex]

So he would not able to meet his goal

Answer: 100.5 square feet

Step-by-step explanation:

To find : surface area of sphere with radius of [tex]2\sqrt{2}feet[/tex]

The formula used to calculate surface area of sphere is = [tex]4\times \pi\times r^2[/tex]

where r is the radius of sphere.

Putting the values we get:

surface area of sphere = [tex]4\times 3.14\times (2\sqrt{2}feet)^2=100.5square feet[/tex]

Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet

Answer:

100.5 square ft

Answer:6

Step-by-step explanation:

The number of hours when the amount Andrew and dave pay for the rentals be equal will be 6 hours.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

From the equation, the two points of Dave's line will be (0, 6) and (2, 9). Then the equation is given as,

(y - 6)[(9 - 6) / (2 - 0)](x - 0)

y = 1.5x + 6

From the equation, the two points of Andrew's line will be (0, 3) and (1, 5). Then the equation is given as,

(y - 3) = [(5 - 3) / (1 - 0)](x - 0)

y = 2x + 3

The number of hours when the amount Andrew and dave pay for the rentals be equal will be calculated as,

2x + 3 = 1.5x + 6

0.5x = 3

x = 6 hours

The number of hours when the sum Andrew and dave pay for the rentals be equivalent will be 6 hours.

More about the line passing through two points link is given below.

Answer:

[tex]n < 8[/tex]

Step-by-step explanation:

[tex]3n - 3 < 21 \\ 3n - 3 + 3 < 21 + 3 \\ 3n = 24 \\ \frac{3n}{3} < \frac{24}{3} \\ n < 8[/tex]

Answer:

$1100

Step-by-step explanation:

Let the total budget = b

amount spent on props + amount spent on equipment = total budget

If 37% of the budget was spent on equipment

The percentage spent on props = 100% - 37% = 63%

63% of the total budget is $693

the above sentence presented as an equation gives :

63/100 x b = 693

to find b, divide both sides of the equation by 100/63

b = $1100
