8 21 over 40 as a decimal

Answer:

120

Step-by-step explanation:

12 and 40

Multiples of 12 = 12,24,36,48,60,72784,96,108,120..

Multiples of 40 = 40,80,120..

Common in both = 120

Answer:

120

Explanation:

The least common multiple (LCM) of two or more whole numbers is the smallest whole number that is divisible by each of those numbers. Basically, the LCM is the smallest number that all the numbers divide into evenly. So for 12 and 40, we get 120 since 120 ÷ 12 = 10, 120 ÷ 40 = 30

Answer: 3.6 > v

Step-by-step explanation:

-24 < 6 - 5v  

First subtract 5 from both sides

-18 < -5v

now divide both sides by -5v

3.6 < v

Now switch the signs because you divided (you also switch signs if you multiply both sides fyi)

3.6 > v

Step-by-step explanation:

How do you read decimals? One way to read decimals is with a place value chart. Notice that the place names are similar to the place names for whole numbers, but the names go in the opposite direction. This is because the values of the places decrease as you move from left to right. Think about how this applies to money: a dime, which is worth one-tenth of a dollar, is worth more than a penny, which is worth one one-hundredth of a dollar.

b² + 10b + 21

Step-by-step explanation:

First: b²

Outer: 7b

Inner: 3b

Last: 21

b² + 7b + 3b + 21 =

b² + 10b + 21

Answer:

[tex](b + 3)(b + 7) \\ b(b + 7) + 3(b + 7) \\ b {}^{2} + 7b + 3(b + 7) \\ b {}^{2} + 7b + 3b + 21 \\ b {}^{2} + 10b + 21[/tex]

Answer:

No. There is not enough money in the budget to buy 15 more sunvisors. The softball team's budget is short by $2.50.

Step-by-step explanation:

If the director pays $90 for 12 visors, then we need to calculate the price of each visor to find out if the director can buy 15 more.

[tex]90/12= 7.50[/tex]

90 divided by 12 = $7.50 per sunvisor.

The budget is $200, so now we need to multiply 15 by 7.50.

[tex]15*7.50=112.50[/tex]

Then you add the product of that to the $90 spent previously.

[tex]90+112.50=202.50[/tex]

And the answer is No. There is not enough money in the budget to buy 15 more sunvisors. The softball team's budget is short by $2.50.

Answer: It will be 50º :)

Step-by-step explanation: 4 hours * 4 = 16, 3*4 = 12, 62- 12 = 50

Answer:

50 degrees

Step-by-step explanation:

16/4 = 4

4 * - 3 = - 12

62 - 12 = 50 degrees

Step-by-step explanation:

let H and F be the sets of students who like hockey and football respectively.

here,

then,

n(H U F)=n(H) + n(F) - n(H n F)

=46+42-17

=88-17

=71

now,

n(H U F)' = n(U) - n(H U F)

=99-71

=28..

Therefore, the number of students who don't play both games are 28.

I hope this will be helpful for you....

Formula:

[tex]length = \sqrt{ {(x _{1} -x_{2} )}^{2} + {(y_{1} -y_{2}) }^{2} } [/tex]

substitute:

Answer:

0.4

Step-by-step explanation:

0.35 is hundredth, and since you always round 5 up, it makes 0.4

Answer:

0.4

Step-by-step explanation:

To figure out the answer, first we need to know how to round. Find the tenths place. That's the first 3 you come upon. Look at the number beside it. It is a five which means you would round up (this is because of the 5 or more raise the floor, four or less let it rest rule) The 3 would then turn into a 4.

Step-by-step explanation:

it is a vertical line it never changes

Answer:

Angle 1 = 41°

Step-by-step explanation:

Since they are both vertical angles

(6x+11)° = (10x-9)°

6x - 10x = -9 - 11

-4x = -20

4x = 20

x= 5.

Therefore,

Angle 1 = 6(5) + 11

Angle 1 = 30 + 11

Angle 1 = 41°
