Box A contains 10 pens that are either red or blue in colour. Box B contains 23 pens that are also either red or blue in colour. The number of blue pens in Box B is twice the number of blue pens in Box A while the number of red pens in Box B is thrice the number of red pens in Box A. Write a pair of linear equations using b as the number of blue pens in Box A and r as the number of red pens in Box A.

Answers

Answer:

b + r = 10 - - (1)

2r + 3b = 23 - - (2)

Step-by-step explanation:

Number of Blue pens in box A = b

Number of red pens in box A = r

BOX A :

Contains 10 pens that are either red or blue

b + r = 10

BOX B:

Contains 23 pens that are either red or blue ;

Red pens in box B = 2 tines the number of red pens in box A

Blue pens in box B = 3 times the number of blue pens in box A

2r + 3b = 23

The area of a square is greater than the area of the circle by 12 cm^2. Find the length of the side of a square if the area of the circle is 36 cm^2?

Answers

Answer:

Adding 12 to the circle area is equal to the square area.

Or

s2 = 12 + A

Where

s = side of square

A = area of circle

So

s2 = 12 + 36

s2 = 48

Solve this for s to get the side length

1A) Quad ABCD is inscribed in the circle. Find x. *

Answers

Answer:

x = 34

Step-by-step explanation:

according to the problem ::

(2x + 9)° + (3x + 1)° = 180° [ since, the opposite angles of a cyclic quadrilateral are supplementary ]

or, 2x + 9 + 3x + 1 = 180

or, 2x + 3x = 180 - 10

or, 5x = 170

or, x = 170 / 5

or, x = 34

therefore, the value of x is 34°

Choices- 333.50, 63.50, 153.50, 166.75

Answers

Answer: 153.50

180-13.25-13.25 = 153.50

The two acute angles are the same so look for the obtuse.

Answer:

153.50

Step-by-step explanation:

Sum of all interior angles of a triangle is 180°.

Option(1): 333.5 is much greater than 180(sum of all angles). 333.5 + 13.25 + angle P = 180, for all +ve values of angle P.

/_P = 180° - 13.25 - 333.5 , /_P is -ve from this which is impossible(for an angle in triangle)

This is incorrect.

Option(2): As it can observed, /_ R is much greater than 90°. It means, it should be greater than 63.50°.

This is incorrect.

Option(3): 153.50 is greater than 90°. Moreover, if /_ R is 153.5, let /_P be x, then,

=> 13.25 + 153.50 + x = 180°

=> x = 13.25. , which is +ve

So we can say /_P = 153.50

Option(4): if /_ R is 153.5, let /_P be x, then,

=> 13.25 + 166.75 + x = 180°

=> x = 0 , which is impossible(as we can see It's not 0)

a rectangular canvas covers 225 square inches on a wall. If the canvas has a height of 18 inches then what is the base?

Answers

Answer:

12.5 Sq inches

Step-by-step explanation: 225 is the area and the formula for area is b*h (base times height) and from the problem, you can see that 18 inches is the height. In this case you would do 225/18 which gives you 12.5 sq inches.

2/3 of the children in a group have a pet dog. Of those who have a dog, 3/4 have a cat as well. What fraction of the children in the group have a dog and a cat?

Answers

Answer:

The  fraction of the children in the group that contains both dog and a cat is [tex]\frac{17}{12}[/tex]

Step-by-step explanation:

The fraction of the children in the group that contains both dog and a cat is presented below:

= Pet dog + cat

[tex]= \frac{2}{3} + \frac{3}{4}\\\\= \frac{8 + 9}{12} \\\\= \frac{17}{12}[/tex]

Hence, the fraction of the children in the group that contains both dog and a cat is [tex]\frac{17}{12}[/tex]
