Answer:

1/3

Step-by-step explanation: Can I get brainliest? Thanks!

5. m∠2 = 180-59-55 = 66

m∠1 = 180-66 = 114

6. 2x+3x+4x=180

x(2+3+4)=180

x(9)=180

x=180/9=20

Plug back in to check:

2(20)+3(20)+4(20)=40+60+80=180

7. (3,8) to (9,24)

(9,24)/(3,8) = (3,3) so scale factor = 3

8. (12,15) to (4,5)

(4,5)/(12,15) = (1/3,1/3) so scale factor = 1/3

HELP ASAP. Find the set.

postnew [5]

Given:

The given sets are:

$U=\{x|x\in N\text{ and }x$

$A=\{x|x\text{ is an odd natural number and }x$

$B=\{x|x\text{ is an even natural number and }x$

$C=\{x|x\in N\text{ and }3$

To find

The set $B\cap U$ .

Solution:

We have,

$U=\{x|x\in N\text{ and }x$

$U=\{1,2,3,4,5,6,7,8,9\}$

$B=\{x|x\text{ is an even natural number and }x$

$B=\{2,4,6,8\}$

Now, $B\cap U$ is the set that contains all the common elements of both sets B and U.

$B\cap U=\{2,4,6,8\}$

$B\cap U=B$

Therefore, the correct option is A.

PLEASE HELP!! I am very confused. WILL GIVE BRAINLY!!!!

erastovalidia [21]

Answer:

x=80, y=15

Step-by-step explanation:

The angle on the opposite side of 100 will be equal to x

We know it is 180-100 so x=80

We know 6y=90

therfore y = 90/6 which equals 15

so y=15 and x=80

An arrow is shot vertically upward at a rate of 240 feet per second from ground level. Use the projectile formula to determine w

Juli2301 [7.4K]

Answer:

After 14.92 seconds, the arrow hits the ground.

Step-by-step explanation:

Given:

Initial velocity of the arrow is, $u=240\ ft/s or 73.152\ m/s$

The arrow goes up and come back to the same starting position. So, initial position is same as that of final position.

Therefore, displacement of the arrow is 0 m.

The displacement of the arrow is given as:

$s=ut-\frac{1}{2}gt^{2}$ (equation 1)

Plug all value in equation 1 and solve for $t$

$0=73.152\timests t-\frac{1}{2} \times9.8 \times t^{2}$

$0=73.152\timests t-4.9 \times t^{2}$

$0=t(73.152-4.9 \times t)$

$73.152-4.9\times t=0$ where $t\neq 0$

$4.9\times t=73.152$

$t=\frac{73.152}{4.9}= 14.92\ s$

∴ After 14.92 seconds, the arrow hits the ground.
