Jasper had 362.25 in his account after two years, per the given statement.

The interest you earn upon interest is known as compound interest. This may be demonstrated with simple math: if you have $100 and that it earns 5% interest every year, you will have $105 at the end of the first year. You'll have $110.25 by the end of the second year.

Given:

Jaspar deposits £2,500

interest rate = 7

Time = 2 year

Compound interest is interest calculated on the aggregate amount rather than the principle amount alone.

Amount = P(1+r/100)^n

=2500(1+7/100)²

=2500(100+7/100)²

= 2500(107/100)²

= 2862.25

C.I.= Amount - Principal

= 2862.25-2500

= 362.25

According to the given statement jasper have 362.25 in his account after 2 years.

The area, in square meters, of the trapezoid is 56.16 m²

A trapezoid with height 5.2m and parallel base is 14.6m and 7m.

We have to find the area of area of this trapezoid.

Area of trapezoid =  1/2(sum of parallel sides)(height)

                             = 1/2(14.6+7)(5.2)

                             = 1/2(21.6)(5.2)

A quadrilateral with as a minimum one pair of parallel aspects is known as, in American and Canadian English, a trapezoid (/ˈtræpəzɔɪd/). In British and other forms of English, a (North American) trapezoid is known as a trapezium (/trəˈpiːziəm/). The transposition of these two terms become a result of an blunders in Charles Hutton's mathematical dictionary.

A trapezoid is always a convex quadrilateral in Euclidean geometry.

The area of the portion of the windshield cleaned by the 10-in wiper blade is 106.85in² .

We have been provided that the Length of blade is 15 inches and the Angle of rotation = 98°

We are required to calculate the area of the portion of the windshield cleaned by the 10-in wiper blade.

We have to solve this by using area of a sector.

Area of a sector = ½r²θ

where θ is in radians.

So, angle of rotation (98°) must first be converted to radians

Converting 98º to radians, we get

98×π/180 = 49π/90

The area of the region swept out by the wiper blade

= (area of the sector where r = 15 and θ = 49π/90) - (area of the sector where r = (15-10) and θ = 49π/90).

So, Area = ½×15²×49π/0 - ½×5²×49π/90

= ½×49π/90(15²-10²)

= 49π/180× (225 - 100)

= 49π/180 × 125

= 1225π/36

Area = 106.8472in²

=106.85 in²

Hence, the area of the portion of the windshield cleaned by the 10-in wiper blade is 106.85in²

∠ABC + ∠BCA + ∠CAB = 180

therefore, ∠ABC = 180 - ∠BCA - ∠CAB

using this formula to solve 4a, 4b and 4c:

4a. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 49 -57 = 26

∠ABC = 26

4b. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 28 -90 = 62

∠ABC = 62

4c. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 38 - 25 = 117

∠ABC = 117

5a. In the Triangle ABC, ∠BCA + ∠CAB + ∠ABC = 180

∠BCA = 180 - ∠CAB - ∠ABC = 180 - 55 - 60 = 65

∠BCA = 65

∠BCD + ∠BCA = 180

therefore substituting for ∠BCA in, ∠BCD = 180 - ∠BCA = 180 - 65 = 115

∠BCD =115

5b. In the Triangle ABC, ∠BCA + ∠CAB + ∠ABC = 180

∠BCA = 180 - ∠CAB - ∠ABC = 180 - 125 - 30 = 25

∠BCA = 25

∠BCD + ∠BCA = 180

therefore substituting for ∠BCA in, ∠BCD = 180 - ∠BCA = 180 - 25 = 155

∠BCD = 155

5c. ∠ABD + ∠CBD = 180

therefore ∠CBD = 180 - ∠ABD = 180 - 132 = 48

∠CBD = 48

In the Triangle BCD, ∠CBD + ∠BDC + ∠BCD = 180

therefore ∠BCD = 180 - ∠CBD - ∠BDC = 180 - 48 - 71 = 61

∠BCD =61

6. 4 angles of a quadrilateral = 360

∠a+110+60+80=360

7. four angles of a quadrilateral = 360

using his formula to solve for ∠a, ∠b and ∠c.

for angle a: ∠a+110+95+63=360

∠a=360-110-95-63=92

∠a = 92
