Why are new offers APRs higher than existing account APRs?
Kamila [148]

Answer:

The APR reflects the interest rate plus the fees you paid directly to the lender or broker or both: origination charges, discount points and any other costs. Those fees add to the cost of the loan, and APR takes them into account. That's why APR is higher than the interest rate.

Which of the following is not an integer?
In-s [12.5K]

Answer:

-\frac{54}{7}

Step-by-step explanation:

The first number is \sqrt{\frac{64}{4} }

We simplify to get:\sqrt{\frac{64}{4} }=\sqrt{16}=4

The second number is -\frac{54}{7}.

This number can be rewritten as 7 \frac{5}{7}=7.714285714287

This is not an integer

The third number is (\frac{-25}{5})^2

We simplify to get: (\frac{-25}{5})^2=(-5)^2=25

This is also an integer.

The correct answer is -\frac{54}{7}.

and their work are 
</span><span>(84)5 (73)9 = 84 + 573 + 9 = 89712    Reina's

Mariana [72]

Answer:

<h2>1,190cm²</h2>

Step-by-step explanation:

The Area of a triangle is expressed  as 1/2 * base * height. If uma is planning to decorate a blanket with a triangular shape that has a base of 5 centimetres and a height of 7 centimetres, area of the blanket will be expressed as shown;

Area of the blanget = 1/2 * 7 * 5

Area of a blanket = 35/2 = 17.5cm²

If she plans to cut out 68 triangles with these dimensions, the total area will be total number of triangles * area of one triangle i.e 68 * 17.5 = 1,190cm²
