Jamal and Keisha went running. Keisha ran 2.4 more miles than Jamal. if Keisha ran 8.5 miles how many miles did Jamal run

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.

Answer:

First, simplify the parentheses. Then, do exponents. Next, multiply. Finally, add and subtract from left to right.

Step-by-step explanation:

Answer:  You always complete multiplication and division before addition and subtraction, working left to right inside the parentheses first.

For example, if your equation was:

23 + (12 x 5 + 6 -7), then you would first complete the multiplication (12 x 5), then add 6 (+6), then subtract 7 (-7), and lastly add 23 (+23) which is outside the parentheses.

Your example:

40 ➗ 1 + 3 - (3 x 7) + (7 - 5)

First: (3 x 7)

second: (7 - 5)

third 40 / 1

fourth: 40 + 3

fifth: 43 - 21

sixth: 22 + 2

=24

Step-by-step explanation:

You should always follow the order of operations rule that follows a sequence of evaluation steps for a given expression. Remember the order using PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right). Therefore, you first complete work in the parentheses for multiplication & division (working left to right) and then addition and subtraction (working left to right). Then you complete any math (following the same order) outside the parentheses.

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.

The total area is obtained by the sum of the areas of each sea/ocean, given as follows:

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.

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).

The 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.

The 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.

Answer:

Square, rectangle, and/or paraellegram

Step-by-step explanation:

Answer:

A composite number is a number that has at least one factor besides 1 and itself, or any number which is not prime (although the number 1 is neither prime nor composite). For example, 91 is a composite number. To determine whether a number is composite, determine whether or not it is prime.

Step-by-step explanation:

I don't know if this is the right answer or thread equation but here

"Which number has factors besides 1 and itself?"

Answer: Composite Number

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2] Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.[3][4]

For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.

The composite numbers up to 150 are:

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134, 135, 136, 138, 140, 141, 142, 143, 144, 145, 146, 147, 148, 150.

a equals negative 37 over 24

Step-by-step explanation:

-a-(7/8)=2/3

Add 7/8 to 2/3.

Multiply the numerator and denominator of each fraction by the other's denominator. This keeps the same value for each fraction but makes them easier to add because they have the same denominator.

(7*3)/(8*3)+(2*8)/(3*8)

(21/24)+(16/24)

Add the fractions (add the numerators and keep the denominator).

(21/24)+(16/24)=37/24 or 1 13/24

-a=37/24

Divide 37/24 by -1.

Answer:

Step-by-step explanation:

you don't have the option to what the drop downs say so I'm giving my best guess as to what they all say based on context.

-----------------------------------------------------------------------------------

Data Set B has distant outliers, so it has a lower MAD.

The smaller MAD of Data Set A suggests that most of the data is less than the mean that is in Data Set B

However, most of the data in Data Set A is (unknown) spread out from the mean than in Data Set B

Therefore, MAD is not reliable when there is an outlier.

------------------------------------------------------------------------------------

I am unsure if these fit the answers the drop-downs give but they make the most sense given the context.

Y=mx+c

We find m first so

m=y2-y1/x2-x1

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

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

I have 2 pairs of parallel sides, but here I have 1 pair of sides that never cross.

Now,

Since, We know that;

In the trapezium, it has only one pair of parallel lines.

And, In a square it has two pairs of parallel lines.

Thus, Here the shape is Trapezium.

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.

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]

Therefore, we can conclude that the unit rate price per ounce for the large box of cereal is $0.20 per ounce.

Answer: 180

Step-by-step explanation:

Answer:

Step-by-step explanation:

A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.

Since we have 19x on both sides, whatever else we do is moot because you can't take 19x from 19x without completing getting rid of the variable.
