a total of $10,000 is invested in two funds, Fund A and Fund B. Fund A pays 5% annual interest and Fund B pays 7% annual interest. The combined annual interest is $630. How much of the $10,000 is invested in Fund A?

Answers

The amount of the 10000  invested in each Fund A is $5,300

First step is to calculate the amount invested in Fund  B

Let x represent the amount invested at 7%

.07x+.05(10000-x)=630

Open the bracket

.07x+500-.05x=630

Collect like terms

.02x=630-500

.02x=130

x=130/.02

x=$6,500

Second step

Now let calculate  How much of the $10,000 is invested in Fund  A

Fund A amount invested=10000-6500

Fund A amount invested=$3500

Inconclusion The amount o of the 10000  invested in each  Fund A is $5,300

Solve by Equation

2 + 3y = 8 equation (1)
4x - y = 2 equation (2)

Equation (1) - (2)

2 - 4x + 3y - y = 8 - 2

-4x + 2y + 2 = 6

in thailand the population of town is 48700 men and 41600 women what percentage of the total percentage are men

Answers

Answer:

53.931339977852% (you can round)

Step-by-step explanation:

You add up 48,700 and 41,600 and you would get 90,300 as the overall population. Then you would put it in fraction form if you want to convert it into a percentage. The fraction form would be 48,700/90,300. You could simplify it to 487/903. Then you do  487            x      . You would cross multiply and get

                                              ___    =    ___

                                              903           100

903x = 48700. Then you would divide each side by 903 and get x = 53.931339977852% (you can round)

Answer:

Approximately 53.9%

To be exact, answer is 48700/903

Step-by-step explanation:

Percentage of men = Men ➗ Total population

48700 + 41600 = 90300

48700/90300 is approximately 0.539

0.539 * 100 = 53.9

Refer to the figure at the right to answer each question. 5. Are points H, J, K, and L coplanar? 6. Name three lines that intersect at X. 7. What points do plane WXYZ and HW have in common? 8. Are points W, X, and Y collinear? 9. List the possibilities for naming a line contained in plane WXKH​

Answers

Problem 5

Answer: Yes the points are coplanar

------------------------

Explanation:

Note how all four points are in the same plane, aka face, along the top of the 3D block. The term "coplanar" simply means "all in the same plane", so that's why the points are coplanar.

In contrast, the set of points {H,J,K,Z} are not all coplanar because H,J,K are in the top plane, while Z is not.

===========================================================

Problem 6

Answer: line segments WX, XY, and XK

------------------------

Explanation:

All three lines mentioned above involve the letter X in some fashion. The order doesn't matter. Also, those lines intersect at the common point X.

===========================================================

Problem 7

Answer: point W

------------------------

Explanation:

The plane WXYZ is the bottom face, in which we can think of as the floor of the building. The segment HW is from the floor and goes up vertically. We can consider this to be like a pole beam of the structure. The plane and segment both have point W in common. Note that the letter "W" is found in the sequences WXYZ and HW, and it's the only common letter.

===========================================================

Problem 8

Answer: The points are not collinear

------------------------

Explanation:

To be collinear, the points must all be on the same straight line. We see that isn't the case with points W, X and Y.

d. 6

Answers

Answer:

answer by your own

Step-by-step explanation:lol

Answer:

D.

Step-by-step explanation:

The first step is to subtract 2 on both sides, so

3(y - 5) + 2 - 2 = 5 - 2

3(y - 5) = 3

Next, multiply by or distribute the 3 on the left side.

3y - 15 = 3

Then, add 15 on both sides.

3y - 15 + 15 = 3 + 15

3y = 18

Finally, divide by 3 on both sides.

3y/3 = 18/3

y = 6

Jon has to pay $7.00 admission for the skating rink in $1.50 per hour to rent rollerblades. How many hours can he skate for $19?

Answers

Answer: 8 hours

Step-by-step explanation:

Given information

Admission fee = $7.00

Hour rent fee = $1.50

Number of hours = h

Total fee = $19

Set equation according to the given information

Total fee = admission fee + (hours) × (hour rend fee)

Substitute values into the equation

19 = 7 + 1.5h

Subtract 7 on both sides

19 - 7 = 7 + 1.5h - 7

12 = 1.5h

Divide 1.5 on both sides

12 / 1.5 = 1.5h / 1.5

[tex]\boxed{h=8}[/tex]

[tex]D)\ 25\%[/tex]

Step-by-step explanation:

The following equation can be used to relate the speed time and distance of an object in motion,

[tex](Speed)*(Time)=(Distance)[/tex]

One can also rewrite this equation in terms of time:

[tex](Speed)=\frac{(Distance)}{(Time)}[/tex]

Let this equation represent the relation between Mr.Wang's initial speed and travel time. However, in this problem, Mr.Wang faced a decrease in his speed,  more specifically, a (20%) decrease. Subtract (0.2) from (1) to find Mr.Wang's speed in relation to his original speed. Let (x) represent the increase in time that Mr. Wang had to incur in order to reach his destination. Model this situation,

[tex](Speed)*(Time)=(Distance)[/tex]

[tex]0.8(Speed)*x(Time)=(Distance)[/tex]

Now use inverse operations to solve for the coefficient (x):

[tex]0.8(Speed)*x(Time)=(Distance)[/tex]

[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]

Using the relation state above: ([tex](Speed)=\frac{(Distance)}{(Time)}[/tex]) one can state the following:

[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]

[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]

Thus, (Time) can be omitted from this equation, as it appear on both sides as a factor, hence one can then solve for (x):

[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]

[tex]x=\frac{1}{0.8}[/tex]

Divide (1) by (0.8):

[tex]x=\frac{1}{0.8}\\x=0.25[/tex]

Multiply the decimal by (100) to put it into the percent form:

[tex]x=0.25\\x=25\%[/tex]
