History test

Step-by-step explanation:

28 divided by 40 is 0.7 which equals 70 percent.

39 divided by 60 is 65 percent .

Answer:

Phil did better on his History test.

Step-by-step explanation:

In the history test, he scored a 28/40. There are many ways to do this, but here is my way. Convert this to decimal to make comparison easy.

28/40 = 0.7

In the Geography test, he scored 39/60. Convert this to decimal as well.

39/60 = 0.65.

Since 0.7 > 0.65, Phil did better on his history test.

Answer:

2nd option

Step-by-step explanation:

Consider the coordinates of T(- 3, 3 ) → T' (3, - 1 )

- 3 → 3 is 6 units right in the positive x-direction

3 → - 1 is 4 units down in the negative y- direction

Then translation rule is

(x, y ) → (x + 6, y - 4 )

The multiples of 4 have an even number in the tens place.What values do they have in the ones place? With multiples of 4 that are larger than 100?

Answers

Answer:

0 , 4 , 8

Step-by-step explanation:

Multiples of 4 = 12,16,18,20, 24, 28.............100, 104, 108, 112, 116,120, 124, 128

Numbers that have even no. in tens = 20, 24 , 28 ... 100, 104, 108, 120 , 124, 128

As evident, all these numbers (including those > 100) have 0, 4, 8 as one's place numbers.

Use the rectangle FOUR to find the value of x.
in FU = 38, RQ = 2x + 9.

Answers

Answer:

x = 5

Explanation:

2x + 9 = 19

2x = 10

x = 5

Applying the properties of the diagonal of a rectangle, the value of x is determined as: 5.

Diagonals of a RectangleThe diagonals of a rectangle are of equal length.The diagonals of a rectangle bisects each other into two equal halves.FU and RO are diagonals of rectangle FOUR.

Therefore:

2(RQ) = FU

Substitute

2(2x + 9) = 38

4x + 18 = 38

4x = 38 - 18

4x = 20

x = 5

Thus, applying the properties of the diagonal of a rectangle, the value of x is determined as: 5.

What is the mean of the following data set: 100, 121, 105, 113, 108

Answers

Answer:

Mean = 109.4

Step-by-step explanation:

Mean = (Sum of all values)/(Number of values)

Mean = (100 + 121 + 105 + 113 + 108)/(5)

Mean = (547)/5

Mean = 109.4

Answer:

The sum of the two angles of the parallelogram is 224 °. Calculations of parallelogram plateau angles?

Answers

Answer:

136degrees

Step-by-step explanation:

The sum of the two angles of the parallelogram is 224 °. Calculations of parallelogram plateau angles?

Note that the sum of interior angle of a parallelogram is 360 degrees

If the sum of two angles of the parallelogram is 224 °, the remaining angle will be expressed as:

Other angles = 360-224

Other angles = 136degrees

Hence the sum of other angles of the parallelogram will be 136degrees

Solve for X

PLEASE HELP DUE IN 10 MINS

Answers

Answer:

x = 8

Step-by-step explanation:

The measures of the angles in a triangle add up to equal 180°

That being said we can create an equation to solve for x

( note that this is a right triangle indicated by the square. A right triangle has a right angle which has a measure of 90° )

180 = 90 + 5x + 5 + 5x + 5

now we solve for x using basic algebra

step 1 combine like terms

90 + 5 + 5 = 100

5x + 5x = 10

now we have 180 = 100 + 10x

step 2 subtract 100 from each side

180 - 100 = 80

100 - 100 cancels out

now we have 10x = 80

step 3 divide each side by 10

10x / 10 = x

80 / 10 = 8

we're left with x = 8

A wheelbarrow has one wheel and a wagon has 4 wheels. Each day, a company has 160 wheels which makes 70 garden vehicles. How many of each vehicle can the company make?

Answers

Answer:

x = number of wheelbarrow = 40

y = number of wagon = 30

Step-by-step explanation:

Let

x = number of wheelbarrow

y = number of wagon

x + y = 70 (1)

x + 4y = 160 (2)

subtract (1) from (2) to eliminate variable x

4y - y = 160 - 70

3y = 90

y = 90/3

y =30

Substitute y = 30 into (1)

x + y = 70 (1)

x + 30 = 70

x = 70 - 30

x = 40

x = number of wheelbarrow = 40

y = number of wagon = 30

The students in two 7th grade classes were asked, "How many text messages did they send over the past weekend?" The data was collected and a dot plot was created for each class. For what values do class A's distribution and class B's distribution overlap?

Answers

Answer:

2, 3, 4, and 5

Step-by-step explanation:

Class A and Class B's distributions overlap for the values of 2, 3, 4, and 5. This can be seen in the dot plot below since all of these values have inputs on both of the class' distributions. Values 0 and 1 are not included because they only have inputs for Class A, while values 6 and 7 are not included because they only have inputs for Class B. In order for the values to overlap they need to be included in both class distributions.

Answer:

2,3,4,5

Step-by-step explanation:

Class A and Class B distribution overlap at 2,3,4 and 5 because if you look at both graphs you can see how they both overlap each other.
