Answer:

<em>The ratio of the diameter of ball A to the diameter of ball B is 10:19.</em>

Step-by-step explanation:

<u>Ratios</u>

A ratio is a relation between two quantities and it's calculated as a division. For example, the ratio between 8 and 4 is 8:4 = 8 / 4 = 2.

We are given the diameters of two balls as follows:

The diameter of the ball A=30mm

The diameter of the ball B=5.7 cm = 57 mm

The ratio of the diameter of ball A to the diameter of ball B is 30:57. Dividing both numbers by 3, we have: ratio=10:19

The ratio of the diameter of ball A to the diameter of ball B is 10:19.

Do the results support or contradict the common belief that the mean body temperature is 98.6degreesF? A. The results contradic

nata0808 [166]

Answer:

A. The results contradict the belief that the mean body temperature is 98.6 °F because both the mean and the median are less than 98.6 °F.

Step-by-step explanation:

Assume the temperature data were those in the table below.

You would have calculated that

Mean = 97.9 °F

Median = 97.9 °F

These observations contradict the belief that the mean body temperature is 98.6 °F.

A 2017 study found the mean oral temperature of more than 35 000 British patients was 97.9 °F.

The height of a triangle is 12 centimeters more than its base. The area of the triangle is 189 square centimeters Find the base

telo118 [61]

Answer:

Step-by-step explanation:

the area of a triangle is

baseline × height / 2

so, we know in our case

b(b+12) = 189 cm²

b² + 12b - 189 = 0

let's try to solve this by completing the square.

that means we try to find the expression

(b + k)² + c

that is equal to

b² + 12b - 189

(b + k)² + c = b² + 2kb + k² + c = b² + 12b - 189

so,

2k = 12

k = 6

and then

k² + c = -189

6² + c = -189

36 + c = -189

c = -225

(b + 6)² - 225 = 0

(b + 6)² = 225

b + 6 = 15

b = 9

so, the baseline b = 9 cm.

the height b+12 = 9+12 = 21 cm.

Firlakuza [10]

The correct answer is ∠Y = 75°
because

45°∠A ∼ ∠X
∠B ∼ ∠Y = 75°
60°∠C ∼ ∠Z

45 + 60 = 105
180 -105 = 75
