Answer:

x = 36, the measure of the angle is 72

Step-by-step explanation:

We can see this because Angle 2x and Angle 72 are verticle angles. Based on this information we know that verticle angles are congruent to each other, meaning the are the same. So that leaves us with an equation to figure out x.

2x = 72

$\frac{2x}{2}$ = $\frac{72}{2}$

x = 36

I need help plz pt.2

Fynjy0 [20]

Answer:

See explanation

Step-by-step explanation:

Consider the sequence $\dfrac{1}{32},\ \dfrac{1}{8},\ \dfrac{1}{2}, 2,\ 8,...$

Rewrite it as

$b_1=\dfrac{1}{32},\\ \\b_2=\dfrac{1}{8},\\ \\b_3=\dfrac{1}{2},\\ \\b_4=2,\\ \\b_5=8...$

The points on the coordinate plane are

$(1,b_1),\ (2,b_2),\ (3,b_3),\ (4,b_4),\ (5,b_5),...$ (see attached graph).

Since

$4=\dfrac{b_2}{b_1}=\dfrac{b_3}{b_2}=\dfrac{b_4}{b_3}=\dfrac{b_5}{b_4}...,$ given sequence is geometric.

Water tank is being filled with water. Before water is pumped in, the water level in the tank is 12 inches high. After 20 minute

zhenek [66]

Answer:

D. H = 2.1t + 12

Step-by-step explanation:

Let us assume the t be the time in minutes

And h be the water level

Now before reaching to the equation that need to be used

before this, determine the inches per minute i.e.

= 54 inches - 12 inches

= 42 inches in 20 minutes.

Now for per minute, it would be

= 42 inches ÷ 20 minutes

= 2.1 inches per minute

After this, multiply the inches per minute with the minutes t and add the sale to the beginning value i.e. 12

So the equation is

H = 2.1t + 12

hence, the last option is correct
