Answer:

Step-by-step explanation:

b=4x+1 h=x+1 A=175

A=bh

Substitute: 175=(4x+1)(x+1)

Expand: 175=4x^2+5x+1

Subtract 175

4x^2+5x-174=0

Solve w/quadratic formula

(-5 + sqrt(25+2784))/8

Simplify: x=6 or -29/4

Distance is positive, so x=6

4x+1=4*6+1=25

Elis [28]

Answer:

Radius is 1 unit

Step-by-step explanation:

The relationship is:

V = πr²h

We have points on the graph:

(9, 28.26) and (18, 56.52)

Use one of the points, substitute into equation and solve for r:

28.26 = 3.14*9*r²
r² = 28.26/28.26
r² = 1
r = 1

Tia types 66 words in 3 minutes. She wants to know how many words she can type in 5 and 10 minutes if she keeps the same rate.

olchik [2.2K]

Answer:

110 words in 5 min, 220 words in 10 min

Step-by-step explanation:

y = mx (there is no intercept because you can't type anything in 0 minutes)

66 = 3m

m = 22

y = 22x

5 minutes:

y = 22(5) = 110 words

10 minutes:

y = 22(10) = 220 words

deff fn [24]

The distance between the police station and the fire station is x.
The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station, so it is 2x-3. This distance is equal to 5 miles.

$2x-3=5 \\
2x=5+3 \\
2x=8 \\
x=\frac{8}{2} \\
x=4$

The police station and the fire station are 4 miles aparat.
