Two angles are complementary angles, if ∠A measures 38 ° , What is the measurement of the other angle?

Answer:

1) 21

2a) -23/30

2b) 6/55

Step-by-step explanation:

1) 3(x + 2) + 5x + 7

expand the brackets:

= 3x + 6 + 5x + 7

collect like terms:

= 8x + 13

when x = 1, (just substitute 1 for x)

8(1) + 13

= 8 + 13

= 21

2a)

-9/10 + 2/15

put both fractions on the same denominator (often we can just multiply each denominator by the other one):

so -9/10 * 15/15

= -135/150

and 2/15 * 10/10

= 20/150

now they're both on the same denominator and we can add the numerators:

-135 + 20 = -115

so our answer is:

-115/150

which we can simplify to:

-23/30

2b)

3/11*2/5

Multiplying fractions is very simple, as it doesn't require to have the same denominators. We can just multiply the numerators by each other and same for the denominators:

3*2 = 6

11*5 = 55

therefore, our answer is:

6/55

A)

3(x+2) + 5x + 7

3x + 6 + 5x + 7

3x + 5x + 6 + 7

put x = 1

3(1) + 5(1) + 6 + 7

3 + 5 + 6 + 7

21

B)

a)

[tex]\sf \rightarrow -\dfrac{9}{10} + \dfrac{2}{15}[/tex]

[tex]\sf \rightarrow -\dfrac{9(15)}{150} + \dfrac{2(10)}{150}[/tex]

[tex]\sf \rightarrow -\dfrac{135}{150} + \dfrac{20}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-135+20}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-115}{150}[/tex]

[tex]\sf \rightarrow \dfrac{-23}{30}[/tex]

b)

[tex]\sf \rightarrow \dfrac{3}{11} \ * \ \dfrac{2}{5}[/tex]

[tex]\sf \rightarrow \dfrac{3*2}{11 *5}[/tex]

[tex]\sf \rightarrow \dfrac{6}{55}[/tex]

Answer:

2.25

Step-by-step explanation:

Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.

We can also represent this as a summation series of

[tex]Σ3( - \frac{1}{3} ) {}^{n - 1} [/tex]

Since we can represent this a summation series, we can use that convergent value is equal to

[tex] \frac{a _{1} }{1 - r} [/tex]

where a1 is initial term and r is common ratio.

R is -1/3

A1 is 3.

[tex] \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25[/tex]

So the answer is 2.25

Answer:

supplementary

Step-by-step explanation:

we have,

3x+15+2x=180

=> 5x +15 = 180

=> 5x = 180-15

=> 5x = 165

=> x = 165/5

=> x= 33

so, 3x+15 = 3*33+15

=> 99+15

=>114

2x = 2*33

=> 99

now we can check if these angles are supplementary

114 + 99 = 180

so, they are supplementary

y=8

I didn't need a equation if they vary directly with each other then if the sign switches from 4 to -4 then -8 must have switched to 8

Answer:

D. Undefined term

Step-by-step explanation:

Points are flat surfaces, named using a capital letter, and have no depth or width because they are on a FLAT plane. Just like lines are named "line A", are on a flat surface, and have no depth or width, points also share these characteristics because they are all on a plane. However, a point is not an undefined term, it is a defined term.

A point is a geometric feature used for the definition of geometric objects

The option which is not a characteristic of a point is option A:

A. Flat surface

The reason for the above selection is as follows:

A point in Euclidean geometry is a concept that defines an exact spatial location

The characteristics of a point are:

A flat surface is defined by three noncolinear points

Therefore;

The given option which is not a characteristic of a point is therefore option A. Flat surface

Answer:

The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.

Step-by-step explanation:

From the bar chart,  we can see that 100 goats were present at fair X and Y

Let us now calculate the percentage of goats at each fair:

Fair X = 100/645 * 100 = 15.5%

Fair Y =100/590 *100 = 16.9 %

Hence there was a greater percentage of goats at fair Y than at fair X.

The bar chart is missing and so i have attached it.

Also, the question is incomplete and the missing part of the question is;

Which of the following statements is supported by the bar chart?

a) The total number of cows, pigs, and horses combined is less at fair X than at fair Y.

b) Fair X has at least 20 more chickens than fair Y.

c) At fair X, the number of sheep is twice the number of horses.

d) The percentage of all animals at fair Y that are goats is equal to the percentage of all animals at fair X that are goats.

e) The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.

The only Statement that supports the bar chart is statement E.

At fair X: Cows = 50, Pigs =60, Horses = 80. Total = 50 + 60 + 80 = 190

At fair Y:  Cows = 60, Pigs = 80, Horses = 40. Total = 60 + 80 + 40 = 180

Total in fair X is greater than total in fair Y. Therefore statement in question is false.

At fair X; chickens = 90

At fair Y; chickens = 80

Difference = 90 - 80 = 10

Thus,statement in question is wrong.

Sheeps = 140

Horses = 80

Twice number of horses is not same as sheep. Thus, statement in question is wrong.

Percentage that are goats = 100/590 × 100 = 16.95%

Total number of animals at fair X = 50 + 60 + 80 + 90 + 100 + 125 + 140 = 645

Percentage that are goats = 100/645 × 100 = 15.5%

The percentages are not equal and so the statement in the question is wrong.
