F Chute Lessons 1.1 - 1.2 Complete the sentence 1. 300 is 10 times as much as

Answers

Answer 1

Answer: 300 time 10 is as much as 10 times 300

Answer 2

Answer: the answer is 30 because 30 times 10 is 300

Option A is the correct answer.

Step-by-step explanation:

We have

1 pound = 16 ounces

12 pound = 12 x 16 ounces = 192 ounces

A shopper bought a 12- pound bag of oranges for 18.75.

That is

Price of 12 pounds = 18.75

Price of 192 ounces = 18.75

$\texttt{Price of 1 ounce = }(18.75)/(192)\n\n\texttt{Price of 1 ounce = }=0.098$

Option A is the correct answer.

18.75 divided by 12 equals about 1.56 so therefore it is C :)

To find whether or not the angles form a triangle, all you have to do is add all of the angles together. To be a triangle, they must equal exactly 180°.

If all of its angles are the same, it’s an equilateral triangle.

If none of its angles are the same, it’s a scalene triangle.

If 2 of its angles are the same, but one is different, it’s an isosceles triangle.

If it has an angle of 90°, it’s a right triangle.

If all of its angles are less than 90°, it’s an acute triangle.

If it has an angle greater than 90°, it’s an obtuse triangle.

1. 86+53+41= 180
It’s a triangle.
None of the angles are the same, it’s scalene.
The angles are all less than 90°, it’s acute.

2. 47 + 84 + 56 = 187
Not a triangle.

3. 70 + 22 + 68= 160
Not a triangle.

4. 54 + 97 + 29= 180
It’s a triangle.
None of the angles are the same, it’s scalene.
It has an angle greater than 90°, it’s obtuse.

5. 33+ 90 + 57 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
It has an angle of 90°, it’s a right triangle.

6. 28 + 64 + 100 = 192
Not a triangle.

7. 11 + 101 + 60= 172
Not a triangle.

8. 94 + 35 + 51 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
It has an angle greater than 90°, it’s obtuse.

9. 52 + 83 + 45 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
The angles are all less than 90°, it’s acute.

10. 65 + 78 + 37 = 180
It’s a triangle.
None of the angles are the same, it’s scalene.
The angles are all less than 90°, it’s acute.

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?

Answers

We know from the question that Store A charges $1200 for repairs and 6% as sales tax.
Then
Amount of sales tax charged by Store A = (6/100) * 1200
   = 6 * 12
   = 72 dollars
Then the total amount charged by Store A = ( 1200 + 72) dollars
   = 1272 dollars
Now coming to Store B. It charges $1350 for repairs and 7% of sales tax.
Amount of sales tax charged by Store B = (7/100) * 1350
   = 945/10
   = 94.5 dollars
Then the total amount charged by Store B = ( 1350 + 94.5) dollars
   = 1444.5 dollars
Amount of money saved by choosing Store A instead of Store B = (1444.5 - 1272) dollars
   = 172.5 dollars
So $172.5 is saved by choosing Store A over Store B.

The total repair cost for each store is the cost of repairs added to the sales tax. The amount of money saved will be the difference between the two total costs.
