What is the slope of this line?
2/3 1/3 -1/3 -2/3

Step-by-step explanation:

[tex]25 = 13 + 2r \\ 25 - 13 = 2r \\ 12 = 2r \\ \frac{12}{2} = r \\6 = r[/tex]

Answer:

∠ B = 54°

Step-by-step explanation:

The angles are supplementary, that is they sum to 180° , then

7x + 14 + 5x - 26 = 180 , that is

12x - 12 = 180 ( add 12 to both sides )

12x = 192 ( divide both sides by 12 )

x = 16

Then

∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°

Step-by-step explanation:

Answer:

Interior angle

176 degrees

Exterior

4 degrees

Step-by-step explanation:

Exterior angle

For any polygon, the measure of the total exterior angle is 360

To get the individual exterior angle, we divide the total by n, which is the number of sides, 90 in this case

We have this as;

360/90 = 4

Interior

To get the measure of each interior angle, we use the formula below;

[(n-2)180]/n

n in this case is 90

So we have

[(90-2)180]/90

= (88 * 180)/90

= 2 * 88 = 176

Answer:

The answer is number C

Step-by-step explanation:

[tex](2x + 6) + (10x - 5) = 61 \\ 12x + 1 = 61 \\ 12x = 60 \\ x = 5 \\ then \\ m < sqr = 2 \times 5 + 6 = 16 \\ m < pqr = 10 \times 5 - 5 = 45[/tex]

Answer:

Step-by-step explanation:

Given points

let ( x1, y1 ) = ( - 2 , 2) and (x2 , y2 ) = (7, 3)

slope of the line (m)

= ( y2 - y1) / (x2 - x1)

= ( 3 -2 ) / ( 7 + 2)

= 1 / 9

Answer: a

Step-by-step explanation:

If a cube is rolled by 30 times then 5 times 2s will make the question the model.

Probability is the occurrence of any event or how likely an event can happen.

Mathematically probability = the number of desired outputs by the number of the possible outcomes.

In the number cube, there are six faces above each of them written one to six later.

The probability of getting 2 at once time will be 1/6 since the number of desired output is only one and possible outcomes are six.

Mathematically(Theoretically) if we roll the cube 30 times then the number of 2s will be 1/6 × 30 = 5 times.

If experimentally if we roll dice and the number of 2s came 5 times then our question will become a model.

So by 5 times, 2s will make the question model.

Answer:

Număr de trandafiri = x = 5 trandafiri

Numărul este garoafe = y = 8 garoafe

Step-by-step explanation:

Pasul 1

Să reprezentăm:

Costul garoafelor = c

Costul trandafirilor = r

Victor are 60 de lei și merge la florărie să-i cumpere mamei sale un buchet de flori.

Dacă ar cumpăra 9 garoafe și 4 trandafiri, ar plăti 47 de lei.

Prin urmare,

9c + 4r = 47 ..... Ecuația 1

Dacă ar cumpăra doar trandafiri, toți banii ar fi suficienți pentru 12 bucăți.

Prin urmare,

12 trandafiri = 60 lei

1 trandafir = r lei

Cross Multiply

12r = 60 lei

r = 60 lei / 12

r = 5 lei

1 trandafir costă 5 lei

Înlocuim 5 cu r în ecuația 1

9c + 4 × 5 = 47

9c + 20 = 47

Colectează ca termeni

9c = 47 - 20

9c = 27

c = 27/9

c = 3 lei

Costul unei garoafe este de 3 lei

Pasul 2

Dar cumpără 13 flori (garoafe și trandafiri) și rămâne cu 5 lei rămași,

60 lei - 5 lei = 55 lei

Asta înseamnă că a cheltuit 55 de lei pe 13 flori.

Lasă

Număr de trandafiri = x

Numărul este garoafe = y

x + y = 13 ......... Ecuația 1

x = 13 - y

Din moment ce, Costul unei garoafe = 3 lei și 1 trandafir = 5 lei

3x + 5y = 55 ...... Ecuația 2

Înlocuim 13 - y cu x în ecuația 2

3x + 5y = 55

3 (13 - y) + 5y = 55

39 - 3y + 5y = 55

Colectează ca termeni

- 3y + 5y = 55 - 39

2y = 16

y = 16/2

y = 8

Rezolvarea pentru x

x = 13 - y

x = 13 - 8

x = 5

Prin urmare:

Număr de trandafiri = x = 5 trandafiri

Numărul este garoafe = y = 8 garoafe

Answer:

He'll pay $110.25

Step-by-step explanation:

To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.

Area of trapezoid = (7 + 4)/2 x 6

Area of trapezoid = 33 sq ft

Area of parallelogram = 4 x 4

Area of parallelogram = 16 sq ft

Total area = 49 sq ft

Cost = 2.25 x 49

Cost = $110.25
