Answer:

18cm

Step-by-step explanation:

Area of Trapezium = 1/2(a + b) h

Where:

A = 352cm^2

h = distance between parallel sides = 16cm

a = 25cm

b = ?

352 = 1/2 (25 + b) 16

352 = (25 + b) 8

352 = 200 + 8b

352 - 200 = 8b

152 = 8b

152/8 = b

19= b

→b = 19cm

The other parallel side is 19cm.

A student earned grades of B, B, A, C, and D. Those courses had these corresponding numbers of credit hours: 4, 5, 1, 5, 4.

yanalaym [24]

Answer:

option D

Step-by-step explanation:

given,

grade earned = B, B, A, C, and D

credit hours: 4, 5, 1, 5, 4

A = 4, B = 3, C = 2, D = 1 F = 0

grade point average (GPA) = ?

= $\dfrac{4\times B+5\times B+1\times A+5\times C+4\times D}{4+5+1+5+4}$

= $\dfrac{4\times 3+5\times 3+1\times 4+5\times 2+4\times 1}{19}$

= $\dfrac{45}{19}$

= 2.36

so, the near option is 2.41

Hence, the correct answer is option D

Write the equation of the circle with center (0,0) and (-1,-3) a point on the circle

saw5 [17]

Answer:

Equation of given circle :- x² + y² = 4

Step-by-step explanation:

The equation of the circle with center (0, 0) and radius r is given by,

x² + y² = r²

It is given that, a circle with center (0,0) and (-1,-3) a point on the circle

To find the radius of circle

radius r = √[(0 - - 1)² + (0 - -3)²] =√(1 + 3) =√4 = ±2

r = 2

To find the equation of circle

x² + y² = r²

x² + y² = 2²

x² + y² = 4

Geometry Question, Need Help. I will give brainliest!

polet [3.4K]

Answer:

1.015

Step-by-step explanation:

I’m not sure if this is right. Since the angles are congruent I set up a proportion: 6x/9x = 7x/11x-4 and simplified down to 0=66x(x-1.015). So the answer is 0, 1.015 but it can’t be zero so just the one. Not sure if it was right to do the proportion but hope this can get you somewhere. I might be completely off.
