Answer:
$1.08
Step-by-step explanation:
You would simply multiply $0.09 and 12. Decimals are frequently multiplied by treating them as whole numbers before placing the decimal point in the result. Where the decimal point is placed in the solution depends on how many digits are present in the factors following the decimal points. For instance, 0.3 x 0.8 equals 0.24.
Points that two lines pass through are given in the table. Match each point of intersection to the correct pair of lines.

5: You need to turn 8 into a fraction over 8. 8*3 = 24, so 24/3. There are 24 1/3 cups in 8.
6: She can fill more than 8 tortillas
8: This one ties back to #5, with the 24/3. You divide 24 by 2, so 12. You'll have 12 groups with 24 pieces in total. (Circle 12 groups of 2)
9: 8 / (2/3) is the same as 8*3/2 which equals 12. 12 tortillas.
10: To get a common denominator for 12/8 and 3/4, you can convert 3/4 to 6/8 [3/4 = 6/8] And since 6 is half of 12, 12/8 - 6/8 = 6/8. Mike can only fill 2 glasses

$0.20
Step-by-step explanation:Hey! Let's help you with your question here!
So, let's start with what we are trying to find and that's the unit rate price per ounce of a large box of cereal. Now, let's focus on what we're given.
Information we know:The large box of cereal is 26 ounces.The cost of the box of cereal is $5.20Explanation:Alright! We've figured out what we know and what we need to find! Now, we can start figuring out how to solve it! Now how do we do that? Well in order to figure out the unit rate price, we need to take the price and divide it by the total quantity. In a formula, it looks like this:
[tex]Unit Rate=\frac{cost}{quantity}[/tex]
If we plug everything into the formula, it would look like this:
[tex]UnitRate=\frac{5.20}{26}[/tex]
[tex]UnitRate=0.20[/tex]

Which equation represents the line through (4, 5) and (0, –3)?
Answer:
y = 2x-3
Step-by-step explanation:
Y=mx+c
We find m first so
m=y2-y1/x2-x1
= -3-5/0-4
= 2
So y=2x+c
Now we find c, so we sub any of points in the line equation!
Sub (4,5) in y=2x+c
5=2(4)+c
-8+5=c
-3=c
So the answer is D !

Question 14
Determine the distance between the points (−5, −3) and (−10, −8).
square root of 7 units
square root of 48 units
square root of 50 units
square root of 250 units
The measures are given as follows:
5. Total area: 2.102 x 10^7 km².
6. Distance between the points: square root of 50 units.
How to obtain the total area?The total area is obtained by the sum of the areas of each sea/ocean, given as follows:
South China Sea: 6.963 x 10^6 km².Artic Ocean: 1.4056 x 10^7 km².To add two numbers in scientific notation, the bases have to be equal, hence:
1.4056 x 10^7 = 14.056 x 10^6 (multiply the base by 10 and subtract by 1 the exponent.
Hence:
6.963 x 10^6 + 14.056 x 10^6 = 21.091 x 10^6 = 2.102 x 10^7 km².
How to obtain the distance between two points?The coordinates of the points are:
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
The equation for the distance is of:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence the distance between the points (−5, −3) and (−10, −8) is of:
[tex]D = \sqrt{(-5 - (-10))^2+(-3 - (-8))^2} = \sqrt{50}[/tex]

Answer:
5. (a) 2.1019×10⁷ km²
14. (c) √50 units
Step-by-step explanation:
You want the total area of the South China Sea and the Arctic Ocean given their individual areas are 6.963×10⁶ km² and 1.4056×10⁷ km², respectively. And, you want the distance between the points (-5, -3) and (-10, -8).
5. AreaThe sum of the areas of the two bodies of water is ...
6.963×10⁶ km² +1.4056×10⁷ km² = (0.6963×10⁶ +1.4056) ×10⁷ km²
= 2.1019×10⁷ km² . . . . . total area
Both of the addends have a precision of 10³ km², so that precision is maintained in the sum.
14. DistanceThe distance between the points is found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-10 -(-5))² +(-8 -(-3))²) = √((-5)² +(-5)²) = √(25 +25)
d = √50
The distance between the points is √50 units.

If the given numbers in problem 5 were multiplied, rather than added, their product would rightly be reported to 4 significant figures. The rule for addition is different from the rule for multiplication.
