Someone quickly help! thanks!

Answer:

x=23°; θ=87°

Step-by-step explanation:

These two angles create what is known as supplementary angles, or 2 angles that add up to 180°. We know this because all horizontal lines are 180° on either side. Since we know the total value of these two angles should equate to 180°, we can set up a simple equation:

93+(3x+18)=180

Now, using algebra, we can solve for x:

111+3x=180

3x=69

x=23

Plugging x back into the equation, we get:

3(23)+18=87

Therefore, the total angle is equal to 87° and x is equal to 23°.

Hope this helps!

A sample of bacteria is growing at a rate of 8% per hour compound continuously. How many hours will it take for the sample to do
Anettt [7]

Answer:

The sample would double in 9 hours

Step-by-step explanation

The number of hours it will take for the sample to double can be found using the 72 rule.

The 72 rule is such that a growth rate would double itself by it is used in dividing the number 72 as shown below:

number of hours =72/8=9 hours

The number of hours it would take the sample to double is 9 hours as computed above.

C: At least: three vans, or two small trucks, or one large truck

Step-by-step explanation:

V=Lhw R=$/ft³

Vv=10.5(6)(6)

Vv=378 ft³

Rv=94.5/378

Rv= 25¢ per ft³

Vs=12(8)6.75

Vs=648 ft³

Rs=162/648

Rs=25¢ per ft³

------

Vl=20(8.75)8.5

Vl=1487.5 ft³

1487.5=648n

2.295=n

------
