8 0

Answer:

1287 / 752538150 ≈ 0.00017%

Step-by-step explanation:

Of the 52 cards, 13 are spades.

There are ₁₃C₈ ways to choose 8 spades from 13.

There are ₅₂C₈ ways to choose 8 cards from 52.

So the probability is:

₁₃C₈ / ₅₂C₈

= 1287 / 752538150

≈ 0.00017%

Answer:

The number of bananas that Emily bought was 6 and the number of peaches that Emily bought was 8

Step-by-step explanation:

<u><em>The complete question is</em></u>

Emily and her children went into a grocery store and she bought $20.80 worth of bananas and peaches. Each banana costs $0.80 and each peach costs $2. She bought a total of 14 peaches and bananas altogether. Determine the number of peaches and the number of bananas that Emily bought

Let

x ----> the number of bananas that Emily bought

y ----> the number of peaches that Emily bought

we know that

She bought a total of 14 bananas and peaches altogether

$x+y=14$ -----> equation A

She bought $20.80 worth of bananas and peaches

$0.80x+2y=20.80$ -----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (6,8)

see the attached figure

therefore

The number of bananas that Emily bought was 6 and the number of peaches that Emily bought was 8

A rope which is 10.3 centimeters long is cut into 4 pieces of equal length. Write an equation to find the length of

alexdok [17]

Answer: x = 10.3 ÷ 4

Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.

An oatmeal cookie recipe calls for 1 1/3 cups of oatmeal for every 4 1/2 cups of flour. Could you increase the recipe proportion

telo118 [61]

The recipe calls for 4/3 cups of oatmeal and 9/2 cups of flour.

If we convert them to a common denominator, we have 8/6 cups of oatmeal and 27/6 cups of flour, so, the ratio is 8:27.

If you use 6 cups of oatmeal and 9 cups of flour, the ratio will become 2:3 and will no longer be proportional.

TL;DR: No.

I Hope this helped.
