Answer:

Choice C

Step-by-step explanation:

f: initial value of 200 decreasing at a rate of 4%

g: initial value of 40 increasing at a rate of 8%

f is decreasing so it must go down starting at 200

That eliminates a and d

g is increasing and starts at 40  That eliminates a

We must look at b and c

g is increasing faster than f is decreasing

Choice C

Answer:

The rate of each train is 74 miles per hour and 90 miles per hour respectively.

Step-by-step explanation:

Given;

distance between the two trains, d = 492 miles

total time traveled by each train before meeting the other, t = 3 hours

Let the speed for the first train = p

Let the speed for the second train = q

Assuming the first train is 16 mph slower than the second train, then;

q = p + 16

Distance = speed x time

492 miles = (p + q) x 3

492 = 3p + 3q

but, q = p + 16

492 = 3p + 3(p + 16)

492 = 3p + 3p + 48

492 - 48 = 6p

444 = 6p

p = 444 / 6

p = 74 miles per hour

q = 74 + 16

q = 90 miles per hour

Therefore, the rate of each train is 74 miles per hour and 90 miles per hour respectively.

Answer:on the circle

Step-by-step explanation:

Point J(-3, 12) is lying on the circle whose center is located at point D(-1, 3).

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have a center of the circle at D(-1, 3)

And point G(-10, 1) is on the circle.

We know the standard equation of the circle when a center is given:

[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]

Where r is the radius of the circle and (h, k) is the center of the circle.

Here (h, k) ⇒ (-1, 3)

The circle equation becomes:

[tex]\rm (x+1)^2+(y-3)^2=r^2[/tex]

Put the point on the circle equation to get the radius of the circle:

[tex]\rm (-10+1)^2+(1-3)^2=r^2[/tex]

[tex]\rm (-9)^2+(-2)^2= r^2\\\\\rm 81+4 = r^2\\\\ \rm r = \sqrt{85} \ units[/tex]

Equation of circle is:

[tex]\rm (x+1)^2+(y-3)^2=85[/tex]

Now put the point J(-3, 12 ) in the circle equation:

[tex]\rm (-3+1)^2+(12-3)^2=85[/tex]

4+ 81 ⇒ 85

It means point J is lying on the circle.

Thus, point J(-3, 12) is lying on the circle whose center is located at point D(-1, 3).

Answer:

Step-by-step explanation:

The formula for amount gotten after a period of time (in years) on a principal which is compounded continuously is given as:

[tex]A = P(1 + r)^t[/tex]

where P = principal (amount borrowed)

r = interest rate

t = number of years

Peter accumulated $7,500 in credit card debt with interest rate as 3.5% per year and he does not make any payments for 10 years.

Therefore, his debt is:

[tex]A = 7500(1 + \frac{3.5}{100})^{10}\\ \\A = 7500 (1 + 0.035)^{10}\\\\A = 7500(1.035)^{10}\\[/tex]

A = $10579.49

Answer:

(5s + 8) is the missing factor.

Step-by-step explanation:

The given expression is 5s² + 23s + 24

We have to convert the given expression into the factored form.

One factor of the expression has been given as (x + 3)

5s² + 23s + 24 = 5s²+ 15s + 8s + 24

                        = 5s(s + 3) + 8(s + 3)

                        = (5s + 8)(s + 3)

So the factors of the expression will be (s + 3) and (5s + 8)

Therefore, the missing factor of the given expression is (5s + 8).

Answer:

180 ml oil

240 g onions

1.35 kg potatoes

1.8 l milk

Step-by-step explanation:

The recipe makes 6 portions and you need 18 portions. Since 6 is 3 times smaller than what you need, just times everything you've been given by 3.

*you can choose to convert into the correct units of measurement before or after dividing. I converted after dividing. Either way works fine though.

1) 60 x 3 = 180 ml

2) 80 x 3 = 240 g

3) 450 x 3 = 1350 g

They want it in kilograms, so divide it by 1,000 to convert. this gives you 1.35 kg.

4) 600 x 3 = 1800 ml

They want it in l, so divide it by 1,000 to convert. this gives you 1.8 l.

Answer:

2.195%

Step-by-step explanation:

Assuming that both planets are a sphere, we have to:

26590 * 28% = 7445.2

7445.2 miles would be the diameter of the moon, now to calculate the volume, we know that the radius is half the diameter, so:

r2 = d2 / 2 = 7445.2 / 2 = 3722.6

and the radius of the planet would be:

r1 = d1 / 2 = 26590/2 = 13295

now the volume of the planet we know is equal to:

v1 = 4/3 * pi * r1 ^ 3

and the volume of the moon would be:

v2 = 4/3 * pi * r2 ^ 3

We want to calculate the percentage by volume, therefore:

v2 / v1 = 4/3 * pi * r2 ^ 3 / 4/3 * pi * r1 ^ 3

v2 / v1 = 3722.6 ^ 3/13295 ^ 3

v2 / v1 = 0.021952

that is, the volume of the moon represents 2.195%

  7.  ∠CBD = 100°

  8.  ∠CBD = ∠BCE = 100°; ∠CED = ∠BDE = 80°

Step-by-step explanation:

7. We presume the angles at A are congruent, so that each is 180°/9 = 20°.

Then the congruent base angles of isosceles triangle ABC will be ...

  ∠B = ∠C = (180° -20°)/2 = 80°

The angle of interest, ∠CBD is the supplement of ∠ABC, so is ...

  ∠CBD = 180° -80°

  ∠CBD = 100°

Answer:

x = 8.5

Step-by-step explanation:

In this question, we are to calculate the value of x.

To calculate this, we shall be utilizing one of the important properties of parallelogram.

This property is that opposite angles of a parallelogram are equal.

This means that mQSR = mSPQ = 4x + 90

Now to finally calculate x, we make use of another important parallelogram property which is that angles of parallelogram which faces each other are supplementary.

This means that they add up to be 180

Since mQSR faces mQRS

This means that;

4x + 90 + 9x -20 = 180

13x + 70 = 180

13x = 110

x = 110/13 which is approximately 8.5

Answer:

  b.  b = 15.0, A = 113.2°, C = 300°

Step-by-step explanation:

The given sides are either side of the given angle, so the Law of Cosines can be used to find the unknown side.

  b² = a² +c² -2ac·cos(B)

  b² = 23² +12.5² -2(23)(12.5)cos(36.8°) = 224.829

  b = √224.829 = 14.99 ≈ 15.0 . . . . . matches choice B

__

For the purpose of selecting the correct multiple-choice answer, this is sufficient working.

__

If you want to find the remaining angles, you can use the law of sines to find one of them. The smallest angle* will be ...

  sin(C)/c = sin(B)/b

  C = arcsin(c/b·sin(B)) = arcsin(12.5/14.9942·sin(36.8°)) ≈ 30.0°

Then angle A can be found from the sum of angles in a triangle:

  A = 180° -36.8° -30° = 113.2° . . . . . also matches choice B

_____

* We choose to find the smallest angle because the largest one may be more than 90°. The Law of Sines is ambiguous in that case. Finding the smaller angle first resolves the ambiguity immediately.
