A diagonal of a rectangle is 8cm and forms an angel measuring 30 with one side.Find the area of the rectangle.

Answers

Answer 1

Answer:

16 * √3 cm² or approximately 27.71 cm²

Step-by-step explanation:

Given the 8 cm length of the diagonal and the 30° (π/6 radians) angle with one of the sides, we can calculate the width and height of the rectangle using:

8 * cos(π/6) = 8 * ((√3)/2) = 4 * √3

8 * sin(π/6) = 8 * (1/2) = 4

Multiply those two values together to get the area and you get

16 * √3 cm²

15 ‒ 5x = 6x + 3 – 2x

Answers

Answer:

x = 4/3

Step-by-step explanation:

15 - 5x = 6x + 3 - 2x

In this kind of equation, we try to seperate the x's and the numbers.

So we add 5x to both sides and subtract 3 from both sides to seperate these values

15 - 3 - 5x + 5x = 6x + 3 - 3 - 2x + 5x

=> 12 = 9x

=> 12/9 = x

=> 4/3 = x

=> x = 4/3

To check, we can plug this in.

15 - 5(4/3) = 6(4/3) + 3 - 2(4/3)

15 - 20/3 = 24/3 + 3 - 8/3

45/3 - 20/3 = 24/3 + 9/3 - 8/3

25/3 = 25/3

So our answer works.

There are 4 roses in a vase of 13 flowers the rest are daisies what is the ratio of all flowers in the vase to daises

Answers

Answer:

The ratio is 13:9

Step-by-step explanation:

Since the rest of the flowers in the vase are daisies, subtract the 4 roses from the 13 flowers. 13 - 4 = 9

There will be 9 daisies in the vase in total. Then they are asking for you to put the ratio of the total flowers to the daisies.

Total Flower = 13

Daisies = 9

The ratio would be 13 to 9.

The ratio of all flowers in the vase to daises is [tex]13:9[/tex]

Let the flowers be F.Let the daisies be D.

Given the following data:

Number of roses = 4 rosesNumber of flowers = 13 flowers

To determine the ratio of all flowers in the vase to daises:

First of all, we would solve for the number of daisies in the vase of flowers.

[tex]Number\;of\;daisies = 13-4[/tex]

Number of daisies = 9 daisies.

Now, we can find the ratio of all flowers in the vase to daises:

[tex]Ratio = F:D\\\\Ratio = 13:9[/tex]

In which situation is it best to use a line graph?

A): when the values on both axes are numbers
B): when a grade distribution is displayed
C): when showing trends
D): when representing parts of a whole

Answers

Answer: C): when showing trends

Step-by-step explanation:

A Line graph connects different points such that it appears as a line. For this reason it is very useful in showing the trend in the movement of values overtime.

When plotting line graphs the independent variable for example 'months' is usually put on the x-axis and a dependent variable such as 'temperature' will be on the y-axis.

When plotted, the line will be able to show just how things have changed overtime such that the change is quite easy to see through the movement of the line.

Step-by-step explanation:

Restaurant A served a greater variety of ages than Restaurant B, because the range of data for Restaurant A is greater than that of Restaurant B.

Range of a data set is the data spread.

Restaurant A is serving a greater variety of ages of people since it has a higher range than that of Restaurant B.

Answer:

1. Served a greater variety of age

2. range

Step-by-step explanation:

Restaurant A served a greater variety of age than Restaurant B, because the range of data for Restaurant A is greater than that of Restaurant B.

=> When we see the box plot, we come to know that the range (maximum - minimum) is greater for Restaurant A.

use pythagorean theorem to find the length of the hypotenuse in the triangle shown below 11 and 60

Answers

Answer: The value of the hypotenuse is 61.

Step-by-step explanation:

So we are given a triangle with two known sides; two legs with values of 11 and 60. We have to use the Pythagorean Theorem to find the value of the hypotenuse.

The Pythagorean Theorem states that, "the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides".

This means that:

a^2 + b^2 = c^2

leg^2 + leg^2 = hypotenuse^2

So just by looking at that, we know that we can just substitute the values in:

11^2 + 60^2 = x^2

121 + 3600 = 3721

sqrt of 3721 = 61

So the hypotenuse value is 61.

Answers

The correct answer is D. 73 • 5 • 74

Explanation:

In mathematics, multiplication can be represented by using the symbol × or the symbol ·. Moreover, multiplication can be also represented just by leaving the numbers or values side by side without any symbol. For example, the expression 5x + y implies 5 should be multiplied by x. In this context, the expression (73)5 • 74  indicates 5 should be multiplied by 74, and the result of this should be multiplied by 73 as the lack of symbol indicates multiplication. Therefore, this is equivalent to 73 • 5 • 74.

mr udoh invested an amount in two separate finance firms in the ratio 3:5
his profit was calculated in 8% and 10% respectively . after a year he recieved a profit an interest of 92000. caculate the total amount invested​

Answers

Answer:

  $994,594.59

Step-by-step explanation:

If the investments were in the ratio 3:5, the returns on those investments were ...

  3×0.08 +5×0.10 = 0.74 . . . . . ratio units

This return is $92,000, so each ratio unit of investment is ...

  $92,000/0.74 = $124,324.32 (and change)

The total investment was 8 ratio units, so was ...

  $124,324.32 × 8 = $994,594.59 . . . . total amount invested.

_____

Check

3/8 of the invested amount earned 8%, so that interest was ...

  $994,594.59×(3/8)×(0.08) = $29,837.84

5/8 of the invested amount earned 10%, so that interest was ...

  $994,594.59×(5/8)×(0.10) = $62,162.16

The total interest earned was $29,837.84 +62,162.16 = $92,000.

write the equation of the line in slope intercept form that passes through (10,21) and (15,36)

Answers

Answer:

y = 3x - 9

Step-by-step explanation:

First, find the slope using rise/run (y2 - y1) / (x2 - x1)

Plug in the points:

(36 - 21) / (15 - 10)

15/5

= 3

Next, plug the slope and a point into the equation y = mx + b to find b (y-int)

y = mx + b

21 = 3(10) + b

21 = 30 + b

-9 = b

Then, plug this into the equation, as well as the slope:

The completion times for a job task range from 10.1 minutes to 19.2 minutes

Generally given that the completion times is uniformly distributed then  the probability that it will require between 12.7 and 16.8 minutes is mathematically represented as

         [tex]P(12.7 < x < 16.8 ) = \frac{ 16.8 - 12.7}{ 19.2 - 10.1 }[/tex]
