Answer:

a) 6 girls

b) 3 more boys than girls

c) Pizza

Step-by-step explanation:

You know that half of 4 is 2, and 4+2=6.

There is 1 full circle and 1 circle that is 3/4.

3/4 of 4 is 3.

4+3 is 7 for the girls.

For the boys, there is 2 full circles and 1 half circle.

Half of 4 is 2.

8+2=10.

10-7=3.

You can clearly see its pizza!!!

Hope this helps! <3

2. 5 is 25% of what number?

ss7ja [257]

Answer:

Step-by-step explanation:

25% is 25 over 100 = 1 over 4 of a number (% means "out of 100")

Setting the number as x means x * 1 over 4 = 2.5

To find x we will divide both sides by 1 over 4, which is also multiplying by 4

2.5 * 4 = 10

Which operation results in a binomial? (3y ^ 6 + 4) (9y ^ 12 - 12y ^ 6 + 16)

AleksAgata [21]

Step-by-step explanation:

Given the expression, $(3y ^ 6 + 4) (9y ^ {12} - 12y ^ 6 + 16)$ , we want to know which sign placed in between the two polynomial will produce a binomial.

Using a plus (+) sign to check:

$= (3y ^ 6 + 4) + (9y ^ {12} - 12y ^ 6 + 16)\\= (3y ^ 6 + 4) + (9y ^ {12} - 12y ^ 6 + 16)\\collect \ like \ terms\\= 9y^{12} +3y^6 - 12y^6 + 16+ 4\\= 9y^{12} - 9y^6 + 20\\$

From the gotten value, it can be seen that the resulting answer produces 3 terms, showing that it results in a trinomial instead of binomial.

Using a plus (-) sign to check:

$= (3y ^ 6 + 4) - (9y ^ {12} - 12y ^ 6 + 16)\\= 3y ^ 6 + 4 - 9y ^ {12} + 12y ^ 6 - 16\\collect \ like \ terms\\= -9y^{12} +3y^6 +12y^6 + 4-16\\= -9y^{12} +15y^6 -12\\$

From the gotten value, it can be seen that the resulting answer produces 3 terms, showing that it results in a trinomial instead of binomial.

<em>Hence none of the operations given results in a binomial</em>

1/5 - 2/15 ×1/5 - 2/15

ValentinkaMS [17]

Answer:

1 /25.

Step-by-step explanation:

Using order of operations, we perform the multiplication first:

1/5 - 2/15 × 1/5 - 2/15

= 1/5 - 2/75 - 2/15 LCD of 5, 15 and 75 is 75 so we have:

15/75 - 2/75 - 10/75

= 13/75 - 10/75 = 3/75

= 1 /25 (answer).
