Answer:

it will take approximately 6.32 annum(years) to reach $40000

Step-by-step explanation:

9.5% of $25000 = $2375

$40000 - $25000 = $15000 so you need to make an interest of $15000 overall to reach $40000

since you make $2375 each year therefore

$15000 ÷ $2375 will give you the number of years to reach $40000

hence 15000 ÷ 2375 = 6.315

approximately = 6.32 annum(years)

Answer:

2 5/7

Step-by-step explanation:

First we need to make the 4 2/7 top heavy so it is easier to subtract :)

4 2/7 = 3 9/7

answer:

4.5m²

explanation:

1. find area of the circle

A(circle)=πr²

A=π(2.3²)

A=16.62m²

2. find area of the square

the diameter of a circle is twice its radius. when you multiply 2.3 by two, you get 4.6. since the circle reaches to the sides of the square, the diameter is also the length of a side on the square.

A(square)=s²

A=4.6²

A=21.16m²

3. subtract the two areas

to find the area of the shaded sector, we need to subtract the area of the circle from the area of the square.

A(shaded)=21.16-16.62

A=4.54097487m²

(be sure to round as necessary)

Step-by-step explanation:

lets say the first is x and the second is y then we can say

x+y=55 ......1

x-y= -1 .......2

by adding 1 with 2 then

x+y+x-y=55+(-1)

==> 2x= 55-1=54

==> x= 54/2=28

if we put x=28 in the 2nd equation then

28-y= -1

==> y=29

Answer:

  t = 200/v

Step-by-step explanation:

The relationship between speed, distance, and time is ...

  d = vt

Solving for t gives ...

  t = d/v

For a distance of d=200 km, the time in hours will be ...

  t = 200/v . . . . . . where v has units of km/hour

angle PSQ = 65 (central angle is 130, which means arc PQ is 130, and half of the arc is the inscribed angle)

angle AQS = 35 (congruent to angle SPR)

arc QR = 50 (180-130)

arc RS = 70 (35*2=70)

arc PS = 110 (35*2, making arc SR 70, subtract all arcs from 360 to get 110.

Answer:

Step-by-step explanation:

The given relationships can be translated to equations using L and W for the length and width of the rectangle. The distance from the center to the short side is L/2, and the distance from the center to the long side is W/2.

  P = 2(L +W) . . . . . formula for the perimeter

  56 = 2(L +W) . . . . . the perimeter is 56 cm

  L/2 = 4 + W/2 . . . . . distance to short side is 4 cm longer

__

Dividing the first equation by 2 gives ...

  28 = L +W

Multiplying the second equation by 2 gives ...

  L = 8 + W

Substituting for L in the first equation, we have ...

  28 = (8 +W) +W . . . . . . use L=8+W

  20 = 2W . . . . . . . . .subtract 8

  10 = W . . . . . . . . divide by 2

  L = 8 +10 = 18 . . . . . find the length

The smaller side is 10 cm; the larger side is 18 cm.

Answer:

6 days

Step-by-step explanation:

In one day, one demolition crew:

One day = [tex]\frac{1}{10} x[/tex]  with x = the entire job

Other demolition crew:

One day = [tex]\frac{1}{15} x[/tex]

Together, they do it in [tex]\frac{1}{10}x\\[/tex] + [tex]\frac{1}{15}x[/tex] = [tex]\frac{3}{30}x + \frac{2}{30}x = \frac{5}{30}x[/tex] [tex]= \frac{1}{6}x[/tex] in one day

So [tex]\frac{1}{6}x[/tex] x 6 = x

so it takes 6 days to complete the work together.

[tex]\sqrt{ { (x2 - x1)}^{2} + {(y2 - y1)}^{2} } \\ \\ = \sqrt{( {5 - ( - 1)}^{2} + {( - 9 - ( - 1)}^{2} )} \\ \\ = \sqrt{ {(5 + 1)}^{2} + {( - 9 + 1)}^{2} } \\ \\ = \sqrt{ {(6)}^{2} + {( - 8)}^{2} } \\ \\ = \sqrt{36 + 64} \\ \\ = \sqrt{100} \\ \\ = 10 \: units[/tex]

total number of boxes= 50

weight of all the boxes= 1175

some boxes= 25kg

and the rest= 20kg

how many of each type are there.

Let the number of the 20kg boxes = x

and the number of the 25kg boxes = (50-x)

so,

20×(x) + 25×(50-x)

= 1175

20x + 1250 - 25x

= 1175

- 5x = - 75 => x = (-75)/(-5)

= 15

(50–15)

= 35

therefore, 20 kg boxes are 15 and 25 kg boxes are 35.

Answer:

The slope of the line is 5.

Step-by-step explanation:

You need to use the slope formula.

Slope Formula: y2 - y1 / x2 - x1

Your coordinates: (0,2) and (-1, -3)

Do -3 - 2 / -1 - 0

This is because the -3 is your y2 and the 2 is your y1

**Same goes with x but different numbers since it is the x coordinates.**

Now, do -3 - 2 first.

The negatives turn into a positive meaning you have to add the two.

But the bigger number 3 is negative so, your answer should contain a negative.

-3 -2 = -5

Do -1 - 0

This should be an addition problem but contain a negative answer.

-1 -0 = -1

-5/-1 as final.

The negatives cancel, and 5/1 is 5

Your slope is 5.

Answer:

The slope of the line is 5

Step-by-step explanation:

Slope(m) formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

y₂ = -3

y₁ = 2

x₂ = -1

x₁ = 0

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-3-2}{-1-0} \\\\m=\frac{-5}{-1}\\\\m=5[/tex]

Hope this helps!

Answer:

1) y=x-4

2)y=x+2

Step-by-step explanation:

You can see on the first one y is just 4 less than x

You can see that the second one (graph) has a slope. As by the points, if you increase x by 0.5 you increase y by one.

Thus, y=x+2

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that neither of the two people selected have traditional insurance = (number of people that chose manage care plan + number of people who dont have any insurance) / total number of people surveryed x [(number of people that chose manage care plan + number of people who dont have any insurance) / total number of people surveryed - 1]

Answer:

80 cm²

Step-by-step explanation:

Let's break down the composite shape into two parts. (Image attached)

⇒ The side length of "a" is 4 cm.

⇒ The side length of "b" is 8 cm.

First, let's find the area of square "a". Keep in mind that the area of a square is the side multiplied by itself.

⇒ (Side)² = A

⇒ (4)² = Area of "a"

⇒ (4)(4) = Area of "a"

⇒ 16 cm² = Area of "a"

Next, find the area of square "b". Keep in mind that the area of a square is the side multiplied by itself.

⇒ (Side)² = A

⇒ (8)² = Area of "b"

⇒ (8)(8) = Area of "b"

⇒ 64 cm² = Area of "b"

Finally, let's sum up the area of square "a" and "b" to find the area of the composite shape.

⇒ Area of composite shape = Area of "a" + Area of "b"

⇒ Area of composite shape = 16 + 64

⇒ Area of composite shape = 80 cm²
