How many 6-digit numbers can be created using8, 0, 1, 3, 7, and 5 if each number is used only once?
Ludmilka [50]

Answer:

600 numbers

Step-by-step explanation:

For six-digit numbers, we need to use all digits 8,0,1,3,7,5 each once.

However, 0 cannot be used as the first digit, because it would make a 5-digit number.

Therefore

there are 5 choices for the first digit (exclude 0)

there are 5 choices for the first digit (include 0)

there are 4 choices for the first digit

there are 3 choices for the first digit

there are 2 choices for the first digit

there are 1 choices for the first digit

for a total of 5*5*4*3*2*1 = 600 numbers

A sporting goods stores sells footballs, basketballs, and volleyballs. A football costs $35, a basketball costs
wlad13 [49]

Answer:

The number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

Step-by-step explanation:

Consider the provided information.

A football costs $35, a basketball costs $25  and a volleyball costs $15.

Let F represents the football, B represents the basketball and V represents the volleyball.

On a given day, the store sold 5 times as many footballs as volleyballs.

F=5V......(1)

They  brought in a total of $3750 that day,

35F+25B+15V=3750......(2)

The money made from basketballs alone was 4 times the money.

25B=4(15V)......(3)

By equation 1, 2 and 3.

35(5V)+4(15V)+15V=3750

250V=3750

V=15

Substitute the value of V in equation 1 and 3.

F=5(15)=75

25B=4(15\times 15)\\B=36

Hence, the number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

Step-by-step explanation:

to find the scale factor, you must divide the two equal sides.

\frac{6}{8}

which equals

Which equals

5.333 repeating or 5 1/3
