If you know what happens in 2/3 of a minute, multiply that number by 3/2 to see what happens in a minute. This is true because you have the proportion

5\dfrac{1}{4}\div \dfrac{2}{3}=x\div 1

And solving for x you have

\dfrac{2}{3}x=5\dfrac{1}{4} \iff x=5\dfrac{1}{4}\cdot \dfrac{3}{2}

Getting rid of mixed fraction, we have 5 1/4=21/4, and thus the final answer is

\dfrac{21}{4}\cdot\dfrac{3}{2}=\dfrac{63}{8}

Anna saves 3 dollars for every 10 dollars she earns.Patrick saves 5 dollars for every 20 dollars he earns.Do the two save money
NNADVOKAT [17]
The two do not save money at the same rate, because if you make common denominators of 20, Anna saves 6 dollars for every 20, while Patrick only saves 5 dollars for every twenty earned. So, Anna ends up saving more than Patrick.

What is the volume??????
Ugo [173]

Answer:

36\:\mathrm{in^3}

Step-by-step explanation:

The area of a prism is given by the product of the base and the height. In this triangular prism, the area of the either base is:

A=\frac{1}{2}\cdot 3\cdot 4=6\:\mathrm{in^2}

The height is marked as 6 inches. Thus, the volume of the prism is:

\frac{1}{2}\cdot 3\cdot 4\cdot 6=\boxed{36\:\mathrm{in^3}}

In parallelogram abcd, ab=14, bc=20, m(angle)b=54. Find to the nearest tenth the length of diagonal bd, and find measure angle d
muminat
It is is a parallelogram, hence we have to face sides equal in length and the opposite angles are also the same. From the given above we have:
ab=14 and its opposite side cd=14
bc=20 and its opposite side da=20

Solving for the diagonal measurement bd, we have consecutive angles are equal to 180°
∠A+∠B=180°
∠A=180°-54°
∠A=126° , ∠B=54° ,∠C=126° and ∠D=54°
bd²=ab²+da²-2(ab)(da)cos126°
bd²=14²+20²-2*14*20cos126°
bd=30.42 unit

Solving for the angle dbc, we have
cos dbc=bc²+bd²-cd²/a*bc*bd
cos dbc=20²+30.42²-14²/2*20*30.42
dbc=21.76°
