Answers

Answer 1

if you add 55% and 45% the total is 100% so 45/100 are girls.  35% of the girls scored and A  so 35/45  is the probability that it is a girl chosen or 7/9. the probability is 7 out of 9.

Complete question :

Room temperature ranges from 20 degrees Celsius to 25 degrees Celcius. Find the range of room temperature in degrees Fahrenheit. Use the formula F-32=1.8C to convert from the Celsius scale to the Fahrenheit scale

Answer:

68°F to 77°F

Step-by-step explanation:

Given that:

Temperature range in degree celcius :

20°C to 25°C

The temperature range in degree Fahrenheit is :

Using the relation :

F-32=1.8C

20°C :

F-32=1.8(20)

F = 36 + 32

F = 68°

25°C :

F-32=1.8(25)

F = 45 + 32

F = 77°

Hence, range of room temperature in Fahrenheit scale is :

68°F to 77°F

Step-by-step explanation:

Initial. Position = (- 850) below sea level

Upward movement = 165m

Deownward movement (descent) = (165m

Change in position : net change

Upward movement + downward movement

Answers

Answer: $2

Step-by-step explanation: 20 percent of 10 is 2

Hope I did this right

The selling cost of the mug is the amount of $12.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 57% on her exam, that corresponds to 67 out of 100.

We have been given that Aden spent $10 on a mug and then sold it, making a 20% profit.

The original cost of the mug is $10.

The selling cost of the mug = original cost + 20% of the original cost

The selling cost of the mug = $10 + 20% of $10

The selling cost of the mug = 10 + (20/100)10

The selling cost of the mug = 10 + 0.20 × 10

The selling cost of the mug = 10 + 2

The selling cost of the mug = $12

Therefore, the selling cost of the mug is the amount of $12.

Answer:

x = 48 degrees

Step-by-step explanation:

Total internal angles:

180 degrees * 3

= 540 degrees

540-105-102-93

= 240

240 = 5x

x = 48

PLS GIVE BRAINLIEST

Answer:

2x = 96º

3x = 144º

Step-by-step explanation:

sum of all angles ina pentagon is 540, so:

2x+3x+105+93+102 = 540

5x+ 300 = 540

5x = 540-300

5x = 240

x = 240/5

x = 48

3x = 48.3

3x = 144

2x = 48.2

2x = 96

proof:

105+93+102+144+96 = 540

Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 6 units long. Point C is on the line x = −3. If the area of ΔABC is 9 square units, then find a possible y-coordinate of point C.
5
6
7
8

Answers

Answer:

y-coordinate is 5 or -1.

Step-by-step explanation:

Point A is at (x, 2) and B is at (x+6, 2). Since AB must lie on the line y=2  and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).

Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).

The area of ΔABC is 6. So,

9 = 1/2 (b)(h)

where b is the base and h is the height.

so b = 6 and h = AC

Solving this for C gives

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.

If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.

Therefore, y-coordinate is 5 or -1.

3. If s varies directly as (r + 1) and s = 8, when r = 3, calculate the value ofr when s = 20.
(4marks)

Answers

Answer:

When s = 20, r = 9

Step-by-step explanation:

Given,

s is directly proportional to (r + 1)

s = k(r + 1)

(k is the constant of proportionality)

When s = 8,

8 = k(3 + 1)

8 = k(4)

8 = 4k

8/4 = k

2 = k

When s = 20,

20 = 2(r + 1)

20 = 2r + 2

20 - 2 = 2r

18 = 2r

18/2 = r

9 = r
