To find:

The simplified form of given expression.

Solution:

We have,

[tex]{\dfrac{2}{5}k-\dfrac35+\dfrac{1}{10}k}[/tex]

On combining like terms, we get

[tex]=\left(\dfrac{2}{5}k+\dfrac{1}{10}k\right)-\dfrac{3}{5}[/tex]

Taking LCM in the parenthesis, we get

[tex]=\left(\dfrac{4k+k}{10}\right)-\dfrac{3}{5}[/tex]

[tex]=\left(\dfrac{5k}{10}\right)-\dfrac{3}{5}[/tex]

[tex]=\dfrac{k}{2}-\dfrac{3}{5}[/tex]

Answers

Answer: 7825 calories

Step-by-step explanation:

Feom the question, we are told that the meals have the following calories content meals having the following calorie counts: 975,520, 1560

.872, 1029,534,362,954, and 1019.

The sum of the calories will be:

= 975 + 520 +1560 + 872 + 1029 + 534 + 362 + 954 + 1019.

= 7825 calories

Sara earned money selling pies and cakes. For the cakes, she made a profit of $200 with an expense of $4 per cake. For the pies, she made a profit of $250 with an expense of $5 per pie. She sold the same number of cakes and pies. How many pies did Sara sell if she earned the same total profit for pies and cakes? Write an equation and then solve for x.​

Answers

50 cakes 50 pies

If each cake is $4 each, and makes a profit of 200, all you have to do is 200 divided by 4 (which is 50)
200/4= 50


Do the same for pies: 250 divided by 5 ( which is also 50!)
250/5=50

Let the Universal Set , S, have 132 elements . A and B are subsets of S. Set A contains 63 elements and Set B contains 35 elements . If the total number of elements in either A or B is 89 , how many elements are in A but not in B?

Answers

Answer:

8 elements

Step-by-step explanation:

From the question given above, the following data were obtained:

Universal set (S) = 132

Set A = 63

Set B = 35

n(AuB)ᶜ = 89

n(A but not in B) =?

Next, we shall determine the number of elements common to both set A and Set B. This can be obtained as follow:

Let the number common to both set A and B be x i.e

(AnB) = x

nA = 63

nB = 35

n(AuB)ᶜ = 89

Universal set (S) = 132

S = nA + nB + n(AuB)ᶜ – (AnB)

132 = 63 + 35 + 89 – x

132 = 187 – x

Collect like terms

132 – 187 = – x

– 55 = – x

Divide both side by –1

x = –55 /–1

x = 55

Thus, the number of elements common to set A and B is 55.

Finally, we shall determine the number of elements in A but not in B as follow:

nA = 63

n(AnB) = 55

n(A but not in B) =?

n(A but not in B) = nA – n(AnB)

n(A but not in B) = 63 – 55

n(A but not in B) = 8

Thus, 8 elements are in set A but not in set B.

Answers

Answer:

a) 96m

b) 2 m/s^2

Step-by-step explanation:

The distance travelled in a velocity time graph as shown in the image is the area of the shape. As such, considering the first 14 seconds, the distance covered will be computed by finding the area of the shape.

Note that the shape to be considered ends t the 14 seconds mark. This shape is a trapezium. The area of  a trapezium is given as

A = 1/2(a + b) h

where a and b are the parallel sides of the trapezium and h is the height As such, the distance covered in the first 14 seconds

= 1/2 (14 + 10) * 8

= 4 * 24

= 96m

The acceleration after 4 seconds

Acceleration is the rate of change of velocity with time, at time 0 second, the velocity is also 0 but at time 4 seconds, the velocity is 8 m/s hence, the acceleration after 4 seconds

= 8/4

2. Since abc is 95, the two angles you have to solve are going to equal 95 when added because they make up the angle ABC so solving it would be like

(2x+23)+(9x-5)=95 you then solve this which would be

2x+23+9x-5 = 95 - Combine like terms

11x+18=95 Subtract 18 both sides

11x=77 divide by 11

Describe the outlier boundaries for the data set.

Any value less than

is an outlier.

Answers

The outlier boundaries for the given data set is: any value that is less than 30 or greater than 46.

What is an Outlier?

An outlier in a data can be defined as any value that is less than Q1 - 1.5 × IQR or greater than Q3 + 1.5 × IQR.

Given the data, 34, 38, 41, 40, 36, 36, 38, 40, we have:

Q1 = 36

Q3 = 40

IQR = Q3 - Q1 = 40 - 36 = 4

Q1 - 1.5 × IQR = 36 - 1.5 × 4 = 30

Q3 + 1.5 × IQR = 40 + 1.5 × 4 = 46

Therefore, the outlier would be: any value that is less than 30 or greater than 46.
