Mathematics
1 answer:
just olya [345]3 years ago
7 0

Answer:

x = 30

Step-by-step explanation:

We start off with 90 degrees

2x + x = 90

Add all like terms

3x = 90

Divide 3 on both sides

\frac{3x} {3} = \frac{90} {3}

x = 30

To check your answer:

Let x be 30

2x + x = 90

2 (x 30) + 30 = 90

60 + 30 = 90

90 = 90

The cost C, in dollars, to have medical records transcribed is a function of time, t in hours. A physician's group spends C(t) =
Contact [7]

Answer:

B. $39550

Step-by-step explanation:

The expression for the function is not well-formatted, find the correct format in the solution bellow

Step one:

given data

We are told that the function of the cost is

C(t) = 0.04t^3- 0.1t^2 + 5.5t

instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above

substituting we have

C(t) = 0.04(100)^3- 0.1(100)^2 + 5.5(100)\\\\\C(t) = 0.04*1000000- 0.1*10000 + 5.5*100\\\\C(t) = 40000-1000+550\\\\C(t) = 39550

$39550

Rhonda planted green beans on 67% of her farm. Rhonda's farm has 598 acres of land. Estimate the number of acres of green beans
Savatey [412]

Answer: 400 acres.

Step-by-step explanation:

We know that 598 is very close to 600, so we can round that amount up.

We also know that 67% is very close to \frac{2}{3} because 2÷3≈0.67 & 67%=0.67

So, we can estimate \frac{2}{3} of 600, which is about 400.

Using 5 miles = 8 km, write 2 m/s in mph.<br> Give your answer as a decimal.
svp [43]

Answer:

4.5 mph

Step-by-step explanation:

2 m/s = (2 m/s)(60)(60) = 7200 m/h or 7.2 km/hr

if 5 miles = 8 km, then 1 km = 0.625 miles

7.2 x 0.625 = 4.5 mph
