Your business loan has a variable interest rate. Next month the annual rate will jump from 6.3% to 7.8%. Your balance is
$1,620,000. How much will your monthly payment go up?

Answers

Answer:

$2,025

Step-by-step explanation:

The monthly payment will be increased by $‭2,025‬.

What is an amount?

The quantity of money anyone has is termed as the amount. Your monthly payment based on the rate of 6.3% per annum is:

= (6.3% * 1,620,000 ) / 12 months

= 102,060‬ / 12

= $‭8,505‬

Now that the rate has gone up to 7.8% per annum, the payment is:

=  (7.8% * 1,620,000 ) / 12 months

= ‭126,360‬ / 12

= $‭10,530‬

Payment went up by:

= ‭10,530‬ - 8,505

= $‭2,025‬

Therefore the monthly payment will be increased by $‭2,025‬.

∆ABE ≅ ∆DCE by SAS Congruence Theorem.

Step-by-step explanation:

The diagram given indicates the following:

<E ≅ <E (vertical angles)

AE ≅ DE

BE ≅ CE

Thus, an included angle, <E, and two side lengths, AE and BE, in ∆ABE are congruent to an included angle, <E, and two corresponding side lengths, DE and CE, in ∆DCE. By the SAS Congruence Theorem, both angles are congruent to each other.

Therefore:

Highest common factor of 15 30 and 45

Answers

Step-by-step explanation:

I believe it is 15...all the numbers can be divided by 15, since 15 is the smallest number it is also the highest common factor only because 30 and 45 can be divided by 15

.......hope it helps!

Answer:

15

Step-by-step explanation:

Find the prime factors for each number as:

45 =3 × 3 × 5

30 = 2 × 3 × 5

15 = 3 × 5

Now identify the common factors and determine the GCF:

Therefore:

HCF = 3 × 5 = 15

C. The MAD for group A is more than the MAD for group B

D. On average, the dogs in group B required more lessons than the

dogs in group A

Answers

Answer:

The mean number of lessons for group A is greater than the mean for group B by 1 MAD

Step-by-step explanation:

Given the table :

_______Mean number of lessons ____ MAD

GRP A _____ 5 ___________________ 2

GRP B _____ 3 ___________________ 2

With group A having a mean number of lessons of 5 and Group B having a mean number of lessons of 3

Mean of A > mean of B ; hence, Group A dlgs tool more lessons to learn the trick than group B dogs.

The mean absolute deviation (MAD), measures how far a value is from the mean

Difference in mean number of lessons :

5 - 3 = 2

2 lessons ;

Number of mean absolute deviations:

Difference / MAD value = 2 / 2 = 1

Answer:

The mean number of lessons for group A is greater than the mean for group B by 1 MAD.

Kate’s father is a baker at the Morning Muffin Bakery. This morning the oven wasn’t working correctly and 2 dozen muffins burned. Kate’s father gave ¼ of what was left to Kate to take to school. He wrapped up ½ of the remaining muffins and sold them to the grocery store down the street. He then wrapped ⅓ of what was remaining and gave them to the coffee shop to sell. That left Kate’s father with a dozen muffins to sell at the bakery. How many muffins did Kate’s dad bake?

Answers

Answer:

64

Step-by-step explanation:

Step 1: 12 divided by 3 = 4. 12+4 = 16.

I need to know what ⅓ of 12 is so I can continue the problem without messing up.

Step 2: 16*2 = 32.

Half of however many are left is 16.

Step 3: 32 divided by 4 is 8. 32+8 is 40. Two dozen is 24. 40 + 24 = 64.

Now we know the answer.
