No. 4 times 4 is 16. 30 minus 16 is 14. 5 times 3 is 15. This means she needs 15 grams and she only has 14 left

Find how many six-digit numbers can be formed from the digits 2, 3, 4, 5, 6 and 7 (with repetitions), if:
Goshia [24]

Answer:

case 1 = 2592

case 2 =  729

case 1 + case 2 =  2916

(this is not a direct adition, because case 1 and case 2 have some shared elements)

Step-by-step explanation:

Case 1)

6 digits numbers that can be divided by 25.

For the first four positions, we can use any of the 6 given numbers.

For the last two positions, we have that the only numbers that can be divided by 25 are numbers that end in 25, 50, 75 or 100.

The only two that we can create with the numbers given are 25 and 75.

So for the fifth position we have 2 options, 2 or 7,

and for the last position we have only one option, 5.

Then the total number of combinations is:

C = 6*6*6*6*2*1 = 2592

case 2)

The even numbers are 2,4 and 6

the odd numbers are 3, 5 and 7.

For the even positions we can only use odd numbers, we have 3 even positions and 3 odd numbers, so the combinations are:

3*3*3

For the odd positions we can only use even numbers, we have 3 even numbers, so the number of combinations is:

3*3*3

we can put those two togheter and get that the total number of combinations is:

C = 3*3*3*3*3*3 = 3^6 = 729

If we want to calculate the combinations togheter, we need to discard the cases where we use 2 in the fourth position and 5 in the sixt position (because those numbers are already counted in case 1) so we have 2 numbers for the fifth position and 2 numbers for the sixt position

Then the number of combinations is

C = 3*3*3*3*2*2 = 324

Case 1 + case 2 = 324 + 2592 = 2916

Step-by-step explanation:

2\pi {r}^{2}  + 2\pi  rh

2(3.14) {(20)}^{2}  + 2(3.14)(20)(11)

6.28(400) + 6.28(220) \\ 2512 + 1381.6 = 3893.6 {mi}^{2}

Is x+3=-5y in standard form?
skad [1K]

Answer:

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is Ax+By=C with the terms containing  x  and  y  on the left side of the equation and a number on the right side.

x+3=-5y

Subtract 3 from both sides.

x=-5y-3

Add 5y.

x+5y=-3

There are 50 students in a class. If 14% are absent on a particular day, find the number of students present in the class. What
Tcecarenko [31]

Answer:

i THINK 43% but im not for sure

Step-by-step explanation:

14% of 50 is 7

so 50-7=43

43(percent there)+7(percent gone)=50 (number of students)

SO 43% is still there.  

SORRY IF IM WRONG have a good night :)
