Pls help with this problem

Mathematics
1 answer:
madam [21]2 years ago
6 0

Step-by-step explanation:

every triangle inscribed into a circle with the baseline being a diameter of the circle must be a right-angled triangle.

therefore,

angle XVY = 90°.

for VY we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the line opposite of the 90° angle, in our case XY).

XY = 2×ZY = 2×17 = 34.

so,

34² = 30² + VY²

VY² = 34² - 30² = 1156 - 900 = 256

VY = 16

A mixture of purple paint contains 6 teaspoons of red paint and 15 teaspoons of blue paint. To make the same shade using the 35
andrew-mc [135]

Answer:

87.5 teaspoons

Step-by-step explanation:

Given that a mixture of purple paint contains 6 teaspoons of red paint and 15 teaspoons of blue paint.

So, Purple paint : Blue paint =  6 :15

To make the same shade the ratio of purple and blue paint must be the same.

In the new mixture, the amount of purple paint =35 teaspoon.

let the amount of red paint =x teaspoon.

So, in the new mixture,

Purple paint : Blue paint =  35 : x

So, to make the same shade, the ratio of purple and red paint must be the same, i.e

35 : x =  6 :15

\Rightarrow \frac {35}{x}=\frac{6}{15}

\Rightarrow x={35\times15}{6}=87.5

Hence, 87.5 teaspoons of red paint required to mix with 35 teaspoons of purple paint to make the same shade.

Here is an array of ten integers 6 4 0 3 9 8 1 7 2 5
garik1379 [7]

Answer:

[4,0,3,1,2,5] and [6,9,8,7]

Step-by-step explanation:

GIVEN:  an array of ten integers 6,4,0,3,9,8,1,7,2,5.

TO FIND: If we partition this array using Quick sort's partition function and using 5 for the pivot. List the elements of the resulting array after the partition finishes.

SOLUTION:

quick sort is a divide and conquer algorithm in which an array is partitioned into sub-arrays about an pivot element by checking whether elements are greater than pivot or and then sub arrays are sorted recursively.

Here 5 is the pivot element.

two arrays will be created, in first array element less than or equal to pivot element are stored in other elements greater than pivot element are stored.

Starting from first element of array

elements in first array will be =[4,0,3,1,2,5]

elements in second array will be =[6,9,8,7]

Hence the resulting array after the partition finishes are [4,0,3,1,2,5] and [6,9,8,7]
