Circle theorem - find p

Mathematics
1 answer:
kow [346]2 years ago
4 0

Answer:

C

Step-by-step explanation:

the angle in a semicircle = 90° , that is the 3rd angle in the triangle.

the sum of the 3 angles in a triangle = 180° , then

p + 90° + 42° = 180°

p + 132° = 180° ( subtract 142° from both sides )

p = 48°

A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people pre
Artyom0805 [142]

Answer:

400 people

Step-by-step explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

\frac{15x}{15} = \frac{12 * 500}{15}  (* means multiplication if you do not know)

\frac{12 * 500}{15} = 100 × 4= 400 people

Largest odd number by using all four (4) cards <br><br> 5,3,2,6
dlinn [17]

Answer:

6523

Step-by-step explanation:

I'm assuming that the question is asking us to rearrange the numbers 5,3,2,6 to obtain the largest possible value that is odd.

In order for a number to have the largest value, the first digit of the number must he the largest possible value. In this case, we see that the largest value is 6, hence the number must begin with 6 i.e 6XXX

We can do the same for the next digit in the hundreds position by picking the largest possible remaining number. In this case, it is the number 5. So the number will look something like this: 65XX

We see that the only  remaining numbers are 3 and 2.

Recall that for a number to be odd, the digit on the ones place must also be odd. Of the remaining numbers, only 3 is odd, hence the last number must be 3. i.e 65X3

Hence the last remaining number is 2
