Multiple 7/9 to the sum of 8 3/7 and 5 11/14

Brums [2.3K]

$\frac{7}{9} \times (8 \frac{3}{7} + 5 \frac{11}{14}) = \\$

$\frac{7}{9} \times (8 \frac{6}{14} + 5 \frac{11}{14} ) = \\$

$\frac{7}{9} \times (13 \frac{6 + 11}{14}) = \\$

$\frac{7}{9} \times (13 \frac{17}{14}) = \\$

$\frac{7}{9} \times (14 \frac{3}{14}) = \\$

$\frac{7}{9} \times ( \frac{14 \times 3 + 3}{14}) = \\$

$\frac{7}{9} \times ( \frac{42 + 3}{14}) = \\$

$\frac{7}{9} \times ( \frac{45}{14}) = \frac{7 \times 45}{9 \times 14} = \frac{5}{2} \\$

Kendra has a bowl containing 10 blue marbles, 15 yellow marbles, 5 green marbles, and 6 red marbles of the same size. She will r

Mice21 [21]

Given:
10 blue marbles ; 15 yellow marbles, 5 green marbles, 6 red marbles
A total of 36 marbles.

Probabilities:
1st marble: red = 6/36
2nd marble: yellow = 15/35

6/36 * 15/35 = 6*15 / 36*35 = 90/1260 = 1/14

The probability that Kendra will draw a red marble and then a yellow marble is 1/14.

Zarrin [17]

Answer:

the rate is: 6 cups of flour per cup of water

Step-by-step explanation:

Recall that rate involve quotient of the two quantities in question:

Then cups of flour per cups of water is the quotient: 2 cups of flour divided by 1/3 cup of water:

$\frac{2}{\frac{1}{3} } =2\,*\,\frac{3}{1} = 6$

this means 6 cups of flour per cup of water

A car traveled at a constant speed. The graph shows how far the car traveled, in miles, during a given amount of time, in hours.

snow_tiger [21]

Answer:

Step-by-step explanation:

A car traveled at a constant speed as shown in the graph.

Distance traveled is on the y-axis and duration of travel on the x-axis.

Point A(3.5, 210) shows,

Distance traveled = 210 miles

Time to travel = 3.5 hours

So the point (3.5, 210) shows the distance traveled by the car in 3.5 hours is 210 miles.

Slope of the line = speed of the car = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{210}{3.5}$

= 60 mph

Now we will find the speed of the car at another point B(1, 60).

If the speed of car is same as the point B as of point A, point B will lie on the graph.

Speed of the car at B(1, 60) = $\frac{\text{Distance traveled}}{\text{Time}}$

= $\frac{60}{1}$

= 60 mph

Hence, we can say that point B(1, 60) lies on the graph.
