Find the length of DE if D is between points C and E, CD = 6.5 cm and CE = 13.8 cm

Answer:

All of the expressions

Step-by-step explanation:

A rational number is one that can be written as a ratio, or a number with a terminating decimal.

All of the expressions are whole numbers, so they are all rational.

Answer:

y=-1

x=2

Step-by-step explanation:

5x-4y=14 multiply by 4

4x+7y=1 multiply by 5

20x-16y=56

20x+35y=5 eliminate by subtracting

-51y=51

y=-1

plug back in to get x

4x+7(-1)=1

x= 2

Answer:

840

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 14 - 7 = 21 - 14 = 7

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 7 , thus

[tex]a_{120}[/tex] = 7 + (119 × 7 ) = 7 + 833 = 840

Answer:

the measure of angle Z is 104

Step-by-step explanation:

the angle z and 76 form a suplementary angle, which they add up to 180.

To find angle z, just subtract 76 from 180.

Answer:

Well, does she earn this interest per month?? or is it per year.

4% of $1000 is $40 dollars

so it would take her 2 years (If this 4% is due every year. if not just change the "year" to months) to reach 80 dollars. She just needs 20 dollars which is half of the 40 she earns per year. half of a year is 6 months so the answer would be

Sonja would need to keep her 1000 dollars in the savings account for 2 and a half years to earn 100 dollars exact.

Answer: B

Step-by-step explanation:

∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.

Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.

Answer:

The mean absolute deviation = 3.5°F

Step-by-step explanation:

The sum of the given temperatures, ∑T, is found as follows;

∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F

The number of days, n, over which the temperature was tracked = 8 days

Therefore, the mean, [tex]\bar x[/tex], of the data set = ∑T/n = 480°F/8 = 60°F

The mean absolute deviation is given by the following formula;

[tex]Mean \ absolute \ deviation = \frac{\sum \limits_{i = 1}^{n} \left | x_i - \bar x \right | }{n}[/tex]

Therefore, we have;

66 - 60 = [tex]\left | 6\right |[/tex] = 6

57 - 60 = [tex]\left | -3\right |[/tex] = 3

61 - 60 =  [tex]\left | 1\right |[/tex] = 1

65 - 60 =  [tex]\left | 5\right |[/tex] = 5

54 - 60 =  [tex]\left | -6\right |[/tex] = 6

62 - 60 =  [tex]\left | 2\right |[/tex] = 2

59 - 60 =  [tex]\left | -1\right |[/tex] = 1

56 - 60 =  [tex]\left | -4\right |[/tex] = 4

The mean absolute deviation is therefore;

The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.

Answer: it is 32.6

Step-by-step explanation:

The orginal number that Gavin was thinking of is 32.60.

Let the orginal number be represented with y

Gavin adds 9 to the original number: 9 + y

The answer is doubled: 2(9 + y)

The answer is 83.2: 2(9+y) = 83.2

In order to determine the value of y, take the following steps:

Divide both sides of the equation by 2

9 + y = 41.60

Subtract 9 from both sides of the equation

y = 41.60 - 9

y = 32.60

people =6

dividing equally to each people

A person got=50/6

so each got 8.33

but practically we cannot give it 8.33 to each so we can give 8 to each

Answer:

(-2.5, -3.5)

Step-by-step explanation:

In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.

1 + (-6) = -5

-5/2 = -2.5

1 + (-8) = -7

-7/2 = -3.5

Answer:

102 degrees

Step-by-step explanation:

Supplement means when both angles are added together they would equal 180. So,

78 + Angle 6 = 180

Angle 6 = 102

[tex]50<x<150[/tex]

Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

Step-by-step explanation:

So he wants to keep his consumption of carbs between the inequalities:

[tex]110<2x+10\text{ and } 2x+10<310[/tex]

So, let's solve both inequalities.

1)

[tex]110<2x+10[/tex]

Subtract 10 from both sides:

[tex]100<2x[/tex]

Divide both sides by 2:

[tex]50<x[/tex]

2)

[tex]2x+10<310[/tex]

Subtract 10 from both sides:

[tex]2x<300[/tex]

Divide both sides by 2:

[tex]x<150[/tex]

So, our inequality is now:

[tex]110<2x+10\text{ and } 2x+10<310[/tex]

Since we solved the equations:

[tex]50<x\text{ and } x<150[/tex]

Written as a compound inequality, this is:

[tex]50<x<150[/tex]

In other words, Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

Step-by-step explanation:

Polygons are 2 dimensional shapes with straight edges (no curved edges). The shape needs to be closed up entirely to be a polygon. It cannot have any intersecting line segments

A can't be a polygon because the shape isn't closed up entirely

C can't be a polygon because it is a 3d shape

D can't be a polygon because it has curved edges.

H can't be a polygon because it isn't closed up (there are no line segments).

I can't be a polygon because polygons cannot have intersecting lines

J can't be a polygon because polygons cannot have intersecting lines
