Answer: hope this helps

Step-by-step explanation:

Write down the numbers, one under the other, with the decimal points lined up.

Put in zeros so the numbers have the same length (see below for why that is OK)

Then add, using column addition, remembering to put the decimal point in the answer.

Find the area of a trapezoid , given the bases b1 = 14 mi and b2 = 25 mi and hight h= 6 mi​
elena55 [62]

Answer:

area = 117

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = \frac{1}{2} h (b₁ + b₂ )

here h = 6, b₁ = 14 and b₂ = 25

A = \frac{1}{2} × 6 × (14 + 25) = 3 × 39 = 117

Solve 11 2/5 = q - 4 2/7 + 2 1/7
RideAnS [48]
I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14

11.4=q-4.29+2.14
11.4=q-2.15
13.55= q

13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20

Find the missing length indicated​
Rina8888 [55]

Answer:

c = 175

Step-by-step explanation:

When the height of a right triangle is shown this way (at right angles with the hypotenuse, It can be found by using the way the hypotenuse is broken up. The following proportion works.

576/x = x / 49          Cross multiply

x^2 = 576 * 49

sqrt(x^2) = sqrt(576*49)

x = 24 * 7

x = 168

But that's not what you want (although it is close).

What you want is the hypotenuse to the small lower triangle

c = ?

a = 49

b = 168

c^2 =  49^2 + 168^2

c^2 = 2401 + 28224

c^2 = 30625

c = sqrt(30625)

c = 175

Write the standard form of the equation of the circle with the center (0,2) that passes through (7,3)
Alex787 [66]

Answer:

x²+y²-4y-46=0

Step-by-step explanation:

the equation of a circle is in the form (x - a)² + (y - b)² = r², where (a,b) is the center of the circle

the equation is (x - 0)² + (y - 2)² = r², where r is the radius. But r is the distance from (0,2) to (7,3)

the distance from two points is given by r² = (x₁ -x₂)² + (y₁ - y₂)²

r²= (0 - 7)² + (2 - 3)²

r² = 49 + 1 = 50

hence the equation is  

                  (x)² + (y - 2)² = 50

                  x²+y²-4y+4 = 50

                 x²+y²-4y-46= 0
