Q1. Three types of coffee beans, A, B and C, are blended in the ratio 3: 5:7 to make a bag of coffee powder. Given that the bag contains 45 kg of coffee powder, find the mass coffee beans A in the
mixture?​

Mass of coffee A beans = 9 kg

Step-by-step explanation:

Coffee A = 3

Coffee B = 5

Coffee C = 7

A : B : C = 3 : 5 : 7

Total ratio = 15

Total mass of the bag = 45 kg

find the mass coffee beans A in the mixture?

Mass of coffee A beans = ratio of coffee A / total ratio × total mass of the bag

= 3/15 × 45

= 1/5 × 45

= (1 * 45)/5

= 45/5

= 9 kg

Mass of coffee A beans = 9 kg

Mass of coffee B beans = ratio of coffee B / total ratio × total mass of the bag

= 5/15 × 45

= 1/3 × 45

= 45/3

= 15 kg

Mass of coffee C beans = ratio of coffee C / total ratio × total mass of the bag

= 7/15 × 45

= (7*45)/15

= 315/15

= 21 kg

whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
