Answer:

tha loojs hard

Step-by-step explanation:

Answer:

y = 9x - 49

Step-by-step explanation:

y2 - y1/ x2 - x1

14 - 5/ 7 - 6

9/1

= 9

y = 9x + b

5 = 9(6) + b

5 = 54 + b

-49 = b

Answer:

Probability[Prime number] = 1/3

Step-by-step explanation:

Given:

Total number between 13 to 21;

13, 14, 15, 16, 17, 18, 19, 20, 21

Find:

Probability[Prime number]

Computation;

Total number between 13 to 21 = 9

Total number of prime number;

13, 17 ,19

Total number of prime number = 3

Probability pf event = Number of favorable output / Total output

Probability[Prime number] = Total number of prime number / Total number between 13 to 21

Probability[Prime number] = 3 / 9

Probability[Prime number] = 1/3

Answer:

x = price of adult tickets = $7

y = price of students tickets = $6

Step-by-step explanation:

Let

x = price of adult tickets

y = price of students tickets

7x + 7y = 91 (1)

14x + 12y = 170 (2)

Multiply (1) by 2 to

14x + 14y = 182 (3)

14x + 12y = 170 (2)

Subtract (2) from (3) to eliminate x

14y - 12y = 182 - 170

2y = 12

y = 12/2

y = 6

Substitute y = 6 into (1)

7x + 7y = 91 (1)

7x + 7(6) = 91

7x + 42 = 91

7x = 91 - 42

7x = 49

x = 49/7

x = 7

x = price of adult tickets = $7

y = price of students tickets = $6

Answer:

x = 4

Step-by-step explanation:

(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.

Knowing that, we can do the following:

Answer:

No, it doesn't matter as they are mutually exclusive events. So, the occuring of one event does not effect another event.

Answer:

A) [tex]f^{-1} (x)=\frac{5x+3}{2}[/tex]

Step-by-step explanation:

[tex]f(x)=\frac{2x-3}{5}[/tex]

[tex]y=\frac{2x-3}{5}[/tex]

[tex]x=\frac{2y-3}{5}[/tex]

[tex]\frac{5x+3}{2} =y[/tex]

[tex]y=\frac{5x+3}{2}[/tex]

So option (A)

Answer: [tex]77\ \text{sq. units}[/tex]

Step-by-step explanation:

Given

The radius of the semi-circle is [tex]r=7[/tex]

We know, area of the circle is [tex]\pi r^2[/tex]

So, the area of the semi-circle is half of it i.e. [tex]\frac{1}{2}\pi r^2[/tex]

Put the value

[tex]\Rightarrow \dfrac{1}{2}\times\pi \times 7^2=76.97\\\Rightarrow \approx 77\ \text{sq. units}[/tex]

The area of the semi-circle is [tex]77\ \text{sq. units}[/tex]

Answer:

x = 70

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

z is ab exterior angle of the triangle , then

x + y = z , that is

x + x - 15 = 125

2x - 15 = 125 ( add 15 to both sides )

2x = 140 ( divide both sides by 2 )

x = 70

Answer:

80 cm²

Step-by-step explanation:

Given 2 similar figures with sides in the ratio a : b , then

ratio of areas = a² : b²

Here ratio of sides = 7 : 14 = 1 : 2

ratio of areas = 1² : 2² = 1 : 4

Thus area of B is 4 times area of A

area of B = 4 × 20 = 80 cm²

Answer:

(x+5)^2

x^2+25

so it's C

here's the answer :

=》

In similar figures, the ratio of the lengths of their corresponding sides are equal and corresponding angles are congruent.

hence, A. equal and congruent is correct.

Answer:

equal and congruent

Step-by-step explanation:

equal and congruent

Answer:

The first term in the sequence is odd-valued and so there are m choices for it.2020 Gauss Contest Solutions Page 19

The second term in the sequence is even-valued and so there are m − 1 choices for it.

Thus, there are a total of m × (m − 1) FT sequences that begin with an odd-valued term

followed by an even-valued term.

Finally, we consider the FT sequences that begin with an even-valued term followed by an

odd-valued term (Parity #4).

Again, there are exactly twice as many odd-valued terms as there are even-valued terms in the

first 2019 terms (since the pattern repeats even, odd, odd).

However in this case, the 2020th term is even and so there are fewer than twice as many odd valued terms as there are even-valued terms.

Thus, there are m2 + m × (m − 1) FT sequences that satisfy the required conditions.

Since there are 2415 such FT sequences, we may solve m2 + m × (m − 1) = 2415 by trial and

error.

Evaluating m2 + m × (m − 1) when m = 30, we get 302 + 30 × 29 = 1770, and so m is greater

than 30.

When m = 33, we get 332 + 33 × 32 = 2145.

When m = 34, we get 342 + 34 × 33 = 2278.

When m = 35, we get 352 + 35 × 34 = 2415, as required.

Answer: (D)

Step-by-step explanation:

Answer:

D) Angle VUX

Step-by-step explanation:

Answer and Step-by-step explanation:

To find the value of x, we must add together the two angles, and equal it to 180.

7x + x + 20 = 180

8x + 20 = 180

Subtract 20 from both sides.

8x = 160

Now divide each side by 8.

x = 20

We get the result to be 20 = x.

Answer:

The answer is 1000.

*Explanation*

Attendance at the football stadium is 100%

100% - 10% = 90%

10% = 100 attendance

900% = 900 attendance

900 + 100 = 1000 attendance

Answer:

Mean of temperatures = 82.3 (Approx.)

Step-by-step explanation:

Given:

Number of days = 7 days

Temperatures in 7 days = 81, 78, 83, 89, 80, 87, 78

Find;

Mean of temperatures

Computation:

Mean = Sum of all observation / Number of observation

Mean of temperatures = Sum of all seven days temperature / Number of days

Mean of temperatures = [81 + 78 + 83 + 89 + 80 + 87 + 78] / 7

Mean of temperatures = 576 / 7

Mean of temperatures = 82.2857

Mean of temperatures = 82.3 (Approx.)

Answer:

The Ross family used it for 15 hours

The Watson family used it for 20 hours

Step-by-step explanation:

We can rewrite this word problem using variables.

[tex](x*40)+(y*20)=1000[/tex] and [tex]x+y=35[/tex]

Now we can split 35 between x and y. Since 35 can't be split into a whole number, I have split it into 17 and 18

(17*40) + (18*20) = 1040

This is close but 40 too much. Since this is 40 off, we need to move 2 more hours to the Watson family.

(15*40) + (20*20) = 1000

This means -

The Ross family used it for 15 hours

The Watson family used it for 20 hours

Answer:

x + 7 ft and  x + 15 ft as the dimensions of the outside border of the walkway.

Step-by-step explanation:

[tex]x^{2} +12x + 20 = (x + 2)(x + 10)[/tex]

The dimensions of the fountain is x + 2 and x + 10

Adding the 5-ft walkway, we get x + 7 ft and  x + 15 ft as the dimensions of the outside border of the walkway.
