Answer:

one-half, 3/8, 1/4, 1/8.

Step-by-step explanation:

Fraction 3/8 is less than 5/8.

If we choose the numerator less than 5 and keep the denominator same, then we will get a fraction less than 5/8.

Lets choose 3, which is less than 5.

So the fraction 3/8 is less than 5/8.

Answer:

22.35 m/s

Step-by-step explanation:

The distance is always a positive unit, so distance traveled (d) = 15 miles

Time (t) = 0.3 hours

Time (t) = 0.3 * 60 = 18 minutes

(1 hour = 60 minutes)

Velocity (v) = ?

The formula of distance is: d = v*t

=> v = d/t = 15/18 = 0.83 miles/minute

we can also calculate velocity is meter/sec, for that

1 minute = 60 sec

=> 18 mins = 18*60 = 1080 sec

1 mile = 1609.34 meters

=> 15 miles = 15 * 1609.34 = 24,140 m

hence,

v = 24,140/1080 = 22.35 m/s

Answer:

£6,000 and  £15,000.

Step-by-step explanation:

This split works out to 2 fractions:  2 / (2 + 5) = 2/7 and  5/(2+5) = 5/7.

So the required amounts are £21,000 * 2/7 = £6,000 and 5/7 * 21,000

= £15,000.

To solve this take (83+1/3) times 10^-2 and then multiple that value by 375. The answer is 312.5

The answer is 311.25

Converting 83 1/3 to simple fraction we get

83 1/3 = 83

Now 83 % of 375 will be

83/100 * 375

= 311.25

Answer:

Step-by-step explanation:

To find out how long it takes to earn $25 in interest on a principal of $500 at a 5% annual interest rate, use the simple interest formula. The calculation reveals it takes 1 year.

The question asks us to determine the time it takes to earn $25 in interest on a principal of $500 at an annual interest rate of 5% using simple interest. The formula for simple interest is Interest = Principal × Rate × Time. We can rearrange this formula to solve for time (Time = Interest / (Principal × Rate)).

Given that the interest earned is $25, the principal is $500, and the rate is 5% (0.05 in decimal form), we substitute these values into our rearranged formula to find the time.

Substituting these into the formula gives us:

Time = $25 / ($500 × 0.05) = $25 / $25 = 1 year

Therefore, it takes 1 year to earn $25 in interest at a 5% annual rate on a $500 principal using simple interest.

Answer:

it is 32 and 7 over 15

Step-by-step explanation:

because when u add 14 and 18 u get 32 and then you add your numerator and your denimator so u will see that it is 32 and 7 over 15

The sum of 14 5/6 and 18 2/9 is 33 1/18, after adding the whole numbers and fractions separately and simplifying.

To find the sum of 14 5/6 and 18 2/9, we must first add the whole numbers and then the fractions separately. The whole numbers add up to 14 + 18, which is 32. To add the fractions 5/6 and 2/9, we need a common denominator, which is 54. Now converting the fractions we get (45/54) + (12/54). Adding these gives us 57/54, which is equal to 1 3/54 or reduced to its lowest terms, 1 1/18. Adding this to the sum of the whole numbers we get 32 + 1 1/18, which equals 33 1/18.

Profit function have domain as set of all non-negative number thus domain of the profit function p(x)=20x-75 will be all non-negative integers so option (D) will be correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

Given the profit function,

p(x)=20x-75

The graph of this function has been shown below which is representing the domain as (∞,∞) but in the our profit function x is the number of lawns that mowing so it will be a whole number and positive number.

Since domain is the set of all x's value thus it will be domain of the function.

Domian → [0,∞).

Hence "Domain of the profit function p(x)=20x-75 will be all non-negative".

The value of 9 2/3-4 1/5 number is 5 7/15 .

To find the value of 9 2/3 - 4 1/5, we first need to convert each mixed number into an improper fraction. For 9 2/3, the improper fraction is (9 × 3 + 2)/3 = 29/3. For 4 1/5, the improper fraction is (4 × 5 + 1)/5 = 21/5.

Next, we need to find a common denominator to subtract these fractions. The least common multiple of 3 and 5 is 15, so we convert each fraction to have this common denominator. The first fraction becomes (29/3) × (5/5) = 145/15, and the second fraction becomes (21/5) × (3/3) = 63/15.

Now we can subtract the second fraction from the first: 145/15 - 63/15 = (145 - 63)/15 = 82/15. To convert this back into a mixed number, we divide 82 by 15 to get 5 with a remainder of 7, so the mixed number is 5 7/15.

Therefore, the answer is 5 7/15.

Answer:

x = 3

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠TRQ is an external angle and ∠RTS, ∠RST are interior angles, hence

45x = 25x + 57 + x

45x = 26x + 57 ( subtract 26x from both sides )

19x = 57 ( divide both sides by 19 )

x = 3

Answer:

x = 3

Step-by-step explanation:

We are given expression for measure of angles of two corners of a triangle, while for the third corner, we know the exterior angle.

We know that the sum of all three angles of a triangle is 180°.

So we can write it as:

[tex] 2 5 x + ( 5 7 + x ) + ( 1 8 0 - 4 5 x ) = 180 [/tex]

[tex]25x+x-45x=180-180-57[/tex]

[tex]-19x=-57[/tex]

Answer:

-1

Step-by-step explanation:

i just got it wrong

B) Translate 4 units down and rotate 180°

Rule for 180° = (x, y) ---- (-x, -y)

Pick one point on Triangle A. (I picked the pointiest point)

(-5, 6)

Now translate 4 units down.

You will now be on (-5, 2)

Rotate 180°

You will now have (5, -2)

And the pointiest point on Triangle B is (5, -2)

So, B is the correct answer.

Option B is correct. The required transformation that will map triangle A to triangle B and illustrate the similarity between the two triangles is translating 4 units down and rotate 180° about the origin

In order to determine the transformation that will map triangle A to B, we need to do the following:

If the coordinate is translated 4 units down as seen from the figure, the resulting coordinate of the vertex on triangle B will be at (5, -6+4) i.e. (5, -2)

We can see that it tallies with a similar coordinate on triangle B. Hence the required transformation that will map triangle A to triangle B and illustrate the similarity between the two triangles is translating 4 units down and rotate 180° about the origin

Step-by-step explanation:

A rectangle has one side that measures = 10 units

the another side that measures = 4 units

Perimeter = 2( Length + width )

Perimeter of this rectangle = 2( 10 + 4 )

                                             = 2(14) = 28 units

We have to find the same measurement units that shows the same perimeter.

1. 4 units 5 units

Perimeter = 2( 4 + 5 ) = 2 × 9 = 18 units

2. 8 units 3 units

Perimeter = 2( 8 + 3 ) = 2 × 11 = 22 units

3. 9 units 7 units

Perimeter = 2( 9 + 7 ) = 2 × 16 = 32 units

There are no another rectangle with the same perimeter.
