Answer:

The measure of [tex]MN[/tex] :

[tex]MN = 8[/tex]

Step-by-step explanation:

To find the measure of [tex]MN[/tex], add the measure of [tex]RO[/tex] and [tex]ES[/tex] together and divide it by 2 to get the actual measure of [tex]MN[/tex]:

[tex]RO =[/tex] 10

[tex]ES =[/tex] 6

[tex]MN =[/tex] unknown

-Finding the measure of [tex]MN[/tex]:

[tex]10 + 6 = \frac{16}{2} = 8[/tex]

[tex]MN = 8[/tex]

So, the measure of [tex]MN[/tex] would be [tex]8[/tex] .

Answer:

The values of a,b and c are 1, -3 and -2 respectively.

Step-by-step explanation:

The general form of quadratic equation is given by :

[tex]ax^2+bx+c=0[/tex] .....(1)

Here, a,b and c are constants

The given equation is :

[tex]x^2-3x-2=0[/tex]

We can also write the above equation as :

[tex]x^2+(-3x)+(-2)=0[/tex] ....(2)

If we compare equation (1) and (2), we get :

a = 1

b = -3 and

c = -2

So, the values of a,b and c are 1, -3 and -2 respectively.

Answer: Boat A should travel 152.8° to reach B

Step-by-step explanation:

The diagram illustrating the scenario is shown in the attached photo. Triangle ABP is formed. A represents the position of boat A. B represents the position of boat B. P represents the position of the port.

We would determine AB by applying the law of cosines

AB² = AP² + BP² - 2AP×BPCosP

AB² = 20² + 25² - 2 × 20 × 25 × Cos45

AB² = 1025 - 707.10678 = 317.89322

AB = √317.89322 = 17.83

We would determine the bearing of B from A by finding angle A. We would apply the sine rule.

AB/SinP = AP/Sin A

17.83/Sin45 = 20/SinA

Cross multiplying, it becomes

17.83 × SinA = 20Sin45 = 14.14

SinA = 14.14/17.83 = 0.79

A = Sin^-1(0.79) = 52.2°

The total angle at A is 65 + 52.2 = 117.2°

The angle formed outside the third quadrant is 117.2 - 90 = 27.2°

Therefore, bearing B from A is

180 - 27/2 = 152.8°

Answer:

-4 <= x <= 0

Step-by-step explanation:

Answer:

Step-by-step explanation:

The given equation is

[tex](x-0.5)^{2} +(y-3.5)^{2} =16[/tex]

This equation belongs to a circle, which center is at (0.5, 3.5) and its radius is 4.

You can deduct its elements, becase this equation of the circle is explicit, which means the constant term represents the square power of the radius. Solving that, we have

[tex]r^{2} = 16\\r=\sqrt{16}\\ r=4[/tex]

Therefore, the radius is 4 units long.

Answer:

1/15

Step-by-step explanation:

There are a total of 10 fruits, 3 of which are apples.

The probability that the first selection is an apple is 3/10.

There are now 9 fruits remaining, 2 of which are apples.  So the probability that the second fruit is an apple is 2/9.

The total probability is (3/10) (2/9) = 1/15.

Answer:the probability is 6/10 or 3/5

Answer:

50

Step-by-step explanation:

10 + (20x2) = 50

Answer:

x = 3.431

Step-by-step explanation:

Given equation is,

[tex]5^{(3x-9)}-10=-2[/tex]

[tex]5^{3x-9}-10+10=-2+10[/tex]

[tex]5^{3x-9}=8[/tex]

By taking log on both the sides of the equation,

[tex]\text{log}(5^{3x-9})=\text{log}8[/tex]

(3x - 9)log5 = log8

3x - 9 = [tex]\frac{\text{log}8}{\text{log}5}[/tex]

3x - 9 = 1.292

3x = 9 + 1.292

x = [tex]\frac{10.29202}{3}[/tex]

x = 3.4306

x ≈ 3.431

Answer:

x=501

Step-by-step explanation:

so to find x we take -8016 divide by -16 which equal 501

The required value of x when dividing -8016, the value obtained is -16, is 501.

On dividing -8016 by x, the value obtained is -16. Find the value of integer

In mathematics to operate and interpret the function to make function simple or more understandable called simplification.

Here,
-16 = -8016/x
x = 8016/16
x = 501

Thus, the required value of x when dividing -8016, the value obtained is -16, is 501.

Step-by-step explanation:

A: divide the tax by the total cost

B: divide the total cost without tax by 100, then multiply by 18

Answer:

B) Is the answer.

Step-by-step explanation:

If you have 15 quarters and 32 pennies, you have more than twice the amount of pennies that you do quarters. There is a small chance that it could be a dime or a nickel but this is unlikely. The chance of a quarter and penny falling out is much greater than a dime or nickle.

Answer:

10 cm * 6 cm = 60 cm²

Step-by-step explanation:

There is a formula to calculate thevarea.

Tthe area of a rectangular (flat) surface is length * width.

If the length is 10 cm and the width is 6 cm then you have found your answer just by substituting those numbers.

Please also note the proper unit of the area, which is in this question defined in square cm. You can easily see why, because cm * cm results in cm². Mathematics (and physics) is wonderful !

Answer:

Town  "A" was going to have a larger population eventually

Town "A" = 3458 inhabitants

Town "B" = 2600 inhabitants

Step-by-step explanation:

Eventually Town  "A" will have a greater population population because it increases in percentage with respect to each year, therefore, there will come a time that its increase will be greater than 50 per year, which is what Town "B" increases.

To calculate the population the first thing is to know that 30 years have passed, then we must calculate that 30-year increase.

For Town "A" the increase would be as follows:

800 * (1.05 ^ 30) = 3457.55 = 3458 inhabitants

For Town "B" the increase would be as follows:

1100 + 50 * 30 = 2600 inhabitants

Thus checking that Town  "A" was going to have a larger population eventually

Answer:

Town A will get eventually have the greater population

Answer:

Variable B is the area of triangular base.

B = 38.5 [tex]in^{2}[/tex].

Variable h is the height of pyramid.

In the given prism, h is 9 inches.

The volume of prism is 346.5 [tex]in^{3}[/tex].

Step-by-step explanation:

Please refer to the attached image for the detailed labeling of all the sides.

[tex]\triangle ABC[/tex] is the triangular base of the prism.

BC is the base of triangular base of the prism.

AP is the height of triangular base.

Area of triangular base is represented by B and is calculated by following formula of area of a triangle.

[tex]Area = \dfrac{1}{2} \times \text{Base}\times \text{Height}[/tex]

[tex]\Rightarrow \dfrac{1}{2} \times 11 \times 7\\\Rightarrow 38.5\ in^{2}[/tex]

Hence, B = 38.5 [tex]in^{2}[/tex].

Height of prism, h = 9 in

h is represented as side BE in the attached image.

It is know that volume of prism is given as :

V = Bh

Putting values of B and h:

Answer:

i dont understand your question

Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.

First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.

141 + 161 = 302

Now, that we know how much Jack saves per month.

Then, we have to find out how many months are in 2 years.

We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.

12 x 2 = 24

Therefore, there are 24 months in two years.

Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.

24 x 302 = 7,248

Thus, Jack will save approximately $7,248 in 2 years.

Answer:

Jack will save $7248 in 2 years.

Step-by-step explanation:

Because we know that Betty saves $161 a month, but it's $141 less than Jack saves each month.

Adding $141 to $161 let's us know how much Jack saves.

$141 + $161 = $302

Jack saves $302 each month.

There are 24 months in 2 years.

$302 × 24 = $7248.
