Answer:

Rounding off the number gave a better approximate of the product of given numbers.

Step-by-step explanation:

We are given the following information:

$48\times 123 = 5904$

Compatible numbers are the numbers that are easy to add, subtract and multiply.

Now, if we use compatible numbers to evaluate the same product we get:

$45\times 120 = 5400$

Now, if we round off the given numbers, we can evaluate the product as:

$50\times 120 = 6000$

Hence, rounding off the number gave a better approximate of the product of given numbers.

Compatible 50 x 120 = 6000

Rounding 50 x 123 =6150

Compatible numbers is closer estimate

If you put them into fractions you get 4/3 and 3/2

Now let's give them the same denominator.

3*2=6 and vice versa

So let's multiply the numerators by the same numbers

4/3= 8/6

And 3/2 = 9/6

The second fraction has more parts cranberry so....
She you should ask for 3 cranberry cubes and 2 Apple cubes!

Solve using system of equations!
Let y=total amount of money and x=hours of overtime.
mall: y=400+15x
movies: y=360+20x
Solve! Set the equations equal to each other to find x.
400+15x=360+20x
40=5x
x=8
After 8 hours of overtime the movies would pay her more.

128.34 as a mixed number in simplest form

katrin2010 [14]

128.34
= 128+ 0.34
= 128+ 34/100
= 128+ (34/2) / (100/2)
= 128+ 17/50
= 128 17/50

128.34 written as a mixed number is 128 17/50~

Priya has a recipe for banana bread. She uses 7 ½ cups of flour to make 3 loaves of banana bread. Andre will follow the same rec

Mnenie [13.5K]

Answer:

Option B)

$b = \dfrac{2}{5}f$

Step-by-step explanation:

We are given the following in the question:

Priya uses $7\frac{1}{2}$ cups of flour to make 3 loaves of banana bread.

Thus, we can write the ration of bread to amount of flour used as:

$\text{Ratio} = \dfrac{3}{7\frac{1}{2}} = \dfrac{3}{\frac{15}{2}} = \dfrac{6}{15}$

Now, b loaves of banana bread using f cups of flour.

This measurement will follow the same ratio.

Thus, we can write:

$\dfrac{b}{f} = \dfrac{6}{15}\\\\b = \dfrac{2}{5}f$

Thus, the correct answer is

Option B)

$b = \dfrac{2}{5}f$

PLEASE HELP...!!!!!!!!!!

tangare [24]

Answer:

Step-by-step explanation:

You have all the information you need to find the area of the circle and then subtracting that from 77 you'll have the area of the rectangle and will be able to figure out the length and height by looking at the answer options.

So the area of a triangle is 1/2(b x h) or (b x h)/2 so the base is 6 and the height is 9 so the area is 54/2 which equals 27. 77 - 27 = 50 so the area of the rectangle is 50. With the answer options provided I can see that <em>the height of the rectangle is 5 and the length is 10.</em>
