5.4

Step-by-step explanation:

Conversion a mixed number 3 2/

5

to a improper fraction: 3 2/5 = 3 2/

5

= 3 · 5 + 2/

5

= 15 + 2/

5

= 17/

5

To find a new numerator:

a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/

5

= 15/

5

b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17

c) Write a previous answer (new numerator 17) over the denominator 5.

Three and two fifths is seventeen fifths

Conversion a mixed number 5 1/

4

to a improper fraction: 5 1/4 = 5 1/

4

= 5 · 4 + 1/

4

= 20 + 1/

4

= 21/

4

To find a new numerator:

a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/

4

= 20/

4

b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21

c) Write a previous answer (new numerator 21) over the denominator 4.

Five and one quarter is twenty-one quarters

Add: 17/

5

+ 21/

4

= 17 · 4/

5 · 4

+ 21 · 5/

4 · 5

= 68/

20

+ 105/

20

= 68 + 105/

20

= 173/

20

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 4 = 20. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - seventeen fifths plus twenty-one quarters is one hundred seventy-three twentieths.

Answer:

Decimal: 5.4
Fraction: 5 2/5 or 27/5

Step-by-step explanation:

Decimal:

5 1/4 = 5.25

-3 2/5 = -3.4
5.25 + 3.55 - 3.4 (Simplified)
= 5.4

Fraction:

-3.55 = -71/20 or -3 11/20

5 1/4 + 3 11/20 - 3 2/5 (Simplified)

= 5 2/5

Answer:

D.

Step-by-step explanation:

According to the dot plot,

3 students spend 0.5 minutes brushing their teeth.

2 students spend 1.5 minutes brushing their teeth.

1 student spends 2.5 minutes brushing their teeth.

2 students spend 3.5 minutes brushing their teeth.

1 students spend 4 minutes brushing their teeth.

So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}

Median: The middle number in a set that is ordered from least to greatest.

In this example, the median is 1.5

Mean: The sum of all values divided by the number of values.

In this set there are 9 values so we’ll divide the sum by 9

In this example, the mean would be:

(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9

18 ÷ 9 = 2

If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Answer:

Answer:

d) (5,4)

Step-by-step explanation:

Answer:

D. (5, 4)

Step-by-step explanation:

First, we need to know how coordinate [order] pair works.

(x, y)

That means, (5, 4) is 5 unit on the x-axis and 4 unit on the y-axis.

East means to the right on the graph (+) ;

South means going downward on the graph (-) ;

West means to the left on the graph (-) ;

North means going upward on the graph (+) .

So first, (5, 4) 5 units east meaning that we are moving the x-axis and moving right. 5 [in the order pair] + 5 [unit east] = 10

After the first step, we have (10, 4)

Moving (10, 4) 4 units south meaning that we are moving the y-axis and moving downward on the graph. 4 [in order pair] - 4 [unit south] = 0

After the second step, we have (10, 0)

Moving (10, 0) 4 units west meaning that we are moving the x-axis again and moving left this time. 10 [in order pair] - 4 [unit west] = 6

After the third step, we have (6, 0)

Moving (6, 0) 4 units north meaning that we are moving the y-axis again and moving upward on the graph. 0 [in order pair] + 4 [unit north] = 4

After the forth step, we have (6, 4)

Moving (6, 4) 1 unit west meaning that we are moving the x-axis again and moving left. 6 [in order pair] - 1 [unit west] = 5

After the final step, we have (5, 4)

Therefore, the answer to this question is D. (5, 4)

Though there is an easier version of this, which require some brain to do, but here's how-

Same above, we need to know that east and west moves sideways (east use +, west use -)

And north and south moves up and down (north use +, south use -)

And then we need to sort out how many steps moves sideways and how many steps moves up & down.

5 units east, 4 units west, and 1 unit west. And we put this in an equation for the x-axis. 5 [original] +5 [units east] -4[units west] -1[units west] = 5

Which would still get us 5 for the x-axis.

4 units south and 4 units north balanced out, which still is 4 for the y-axis.

Put the order pair together: (5, 4)

And we got the same answer: D. (5, 4)

I hope this helps!

Answer:

The answer is C. But I got 350.82

Step-by-step explanation:

The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48

The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82

Then we add up all the areas 302.82+48 to get 350.82

Because this answer is slightly different I would assume it is C.

Answer: 62 miles per day

Step-by-step explanation:

3100 = 50x

3100/50 = 50x/50

62 = x

A person has to run 62 miles each day to complete the Self Transcendence 3,100-mile race in 50 days.

In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.

To find out how many miles a person has to run each day, we need to solve the equation:

3100 = 50x

Dividing both sides by 50, we get:

62 = x

Therefore, a person has to run 62 miles each day to complete the Self-Transcendence 3,100-mile race in 50 days.

Answer: 8634

Step-by-step explanation:

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

In this case we are rounding 8633.6 (the decimal number being 6) which is in the round up numbers, so in that case we are rounding up to 8634

The required, rounded value is 8634 grams.

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
Gram is a unit of measurement for mass. To round 8633.6 to the nearest gram, we need to look at the digit in the thousandth place, which is 6. Since 6 is greater than or equal to 5, we round up to the nearest gram. Therefore, the rounded value is 8634 grams.

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

#1 = 10.71% decrease (not sure if you should write -10.71%)

#2 = 49.29% decrease (-49.29%) (-49.30% rounded)

#3 = 5.4% increase

#4 = 34.26% decrease (-34.26%. -34.27 if your teacher wants it rounded.)

Step-by-step explanation:

Original:28

New:25

Increase ÷ Original Number × 100.

28-25 =3

3/28 = 0.1071

0,1071*100= 10.71

Original:21.2

New:10.75

21.2-10.75= 10.45

10.45/21.2 = 0.4929

0.4929*100 = 49.29 (49.30)

Original:37

New:39

difference = 2

2/37 = 0.054

0.054*100 = 5.4

Original: $4.29

New:$2.82

4.29-2.82 = 1.47

1.47/4.29 = 0.3426

0.3426*100 = 34.26 (34.27)

The length of side XY on the coordinate plane is 4 units.

The distance between two points is the length of the line segment joining them.

Given that a coordinate plane, a rectangle has 4 points. Point W is (-5, 3), point X is (0, 3), point Y is (0, -1), and point Z is (-5, 0).

Distance between two points = \(\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Therefore,

XY = \(\sqrt{(0-0)^2+(-1-3)^2}\)

XY = \(\sqrt{4^2}\)

XY = 4

Hence, the length of side XY on the coordinate plane is 4 units.
