Answer:

the answer is C: eleven and forty two ninetieths pounds

Step-by-step explanation:

The total number of pounds of fruit that Frankie bought is 11 + 42/90 pounds, which is the same as option (C), eleven and forty-two ninetieth pounds.

The addition operation in mathematics adds values on each side of the operator.

For example 4 + 2 = 6

To find the total number of pounds of fruit that Frankie bought. Since both amounts are already given in pounds, we don't need to convert them.

Next, we need to add the two amounts together. Six and twelve fifteenth pounds can be written as 6 + 12/15 pounds, and four and four-sixths pounds can be written as 4 + 4/6 pounds. Adding these two amounts together, we get 6 + 12/15 + 4 + 4/6 pounds = 11 + 42/90 pounds.

Therefore, the total number of pounds of fruit that Frankie bought is 11 + 42/90 pounds, which is the same as option (C), eleven and forty-two ninetieth pounds.

Answer:  48) D. 4        49) C. N1.40

Step-by-step explanation:

A $2 postal money order actually costs $2.15

$10.00 ÷ $2.15 = 4.65

Since you can't purchase a fraction of a money order, the most you can buy is 4

4 money orders will cost  $2.15 × 4 = $8.60

The change from $10.00 will be  $10.00 - $8.60 = $1.40

Answer:

(x,y) → (ax,ay) .

Step-by-step explanation:

A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.

If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).

So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of a:

(x,y) → (ax,ay) .

Answer:

[tex]\huge\boxed{(ax, ay)}[/tex]

Step-by-step explanation:

In order to dilate the coordinates of a point, we want to make it [tex]a[/tex] times bigger. In order to do this, we can multiply the x and y values by our scale factor, a. This is called mapping. What it does is it basically multiplied our points by a specific number so that we end up with a figure that is [tex]a[/tex] (the scale factor) times bigger than the original.

So in order to make an expression for this, we multiply the x and y coordinates by a. So we have ax and ay.

Answer:

$128

Step-by-step explanation:

your looking for 16/8, divide 16 by 3, leaving you with 5.333...

now times that by $24, and you have your answer hope this helps

The price of 2 tons of gravel is $128.

Given:

The price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.  

To find:

The price of 2 tons of gravel.

Explanation:

Let [tex]x[/tex] be the price of 1 ton of gravel.

Then the price of [tex]\dfrac{3}{8}[/tex] ton is [tex]\dfrac{3}{8}x[/tex] and the price of 2 tons of gravel is [tex]2x[/tex].

It is given that the price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.  

[tex]\dfrac{3}{8}x=24[/tex]

[tex]x=\dfrac{8}{3}\times 24[/tex]

[tex]x=8\times 8[/tex]

[tex]x=64[/tex]

Now, the price of 2 tons of gravel is:

[tex]2x=2(64)[/tex]

[tex]2x=128[/tex]

Therefore, the price of 2 tons of gravel is $128.

Answer:

10 miles

Step-by-step explanation:

Find how much she runs during one track practice by dividing 8 by 4. This gives you the equation 2x, with x being the number of track practices.

Answer: 10 miles after 5 track practices.

Step-by-step explanation: Lets find the unit rate of this problem. Remember that unit rate means the denominator will always have a 1.

8/4 converted to a unit rate is 2/1

The unit rate is 2 miles per every 1 track practice.

We can use the unit rate to solve how many miles Leslie would have ran after 5 track practices.

2/1 x 5 = 10/5

So, Leslie would have ran 10 miles after 5 track practices.

Steps to solve:

x/6 = 8

~Simplify

1/6x = 8

~Multiply 6 to both sides

x = 48

6.384 rounded to one decimal place is 6.4

Step-by-step explanation:

The number rounded to one decimal place is 6.4.

To change a number into an approximation having fewer significant digits.

Given that, 6.384 to 1 decimal place,

Rounding 6.384 to one decimal place would be the same as rounding it to the nearest tenth.

The tenth in this number is 3. To round a number up, look at the number to the right of it - if the number is 5 or greater, then you increase the value of the number you're rounding by 1. If the number to the right of it is 4 or less, then the value of the number you're rounding stays the same.

In this case, the number we're rounding is 3 and the number to the right of it is 8. Since 8 is greater than 5, we have to increase the value of 3 by 1, which means that the number in the tenths position is now 4.

Hence, The number rounded to one decimal place is 6.4.

Answer:

The answer is -5 and 5 because when you do absolute value if there is a negative number then it turns into a positive number. Negatives will always turn out as positives when doing absolute value. :)

Step-by-step explanation:

Answer: the two numbers that have the same absolute value is -5, and 5.

Step-by-step explanation:

Absolute will just make any negatives to positive.

So, the absolute value of -5 is 5,  or the absolute value of -3, is 3.

If it's already positive, then nothing happens; it stays the same

So, the absolute value of 8 is 8, nothing is changed.

Answer:

Step-by-step explanation:

(x - 3)/2 = -1

x - 3 = -2

x = 1
