Well if she’s doing a two month membership she will have to pay $215
This is because if you follow the y=mx+b form you get b=175 Bc that represents the cost for application and the m=20 Bc it’s 20 dollars per month. This then means the 2 is the x because it’s that’s the value/the months. So then y=20(2)+175, 20(2)=40, 40+175=215, y=$215

On a scale drawing 2 centimeters represent 50 meters. How many centimeters represent 5 meters?
Tanya [424]

Answer:

0.2 centimeters

Step-by-step explanation:
Strategy 1:

Make the equation: 5=a•s, where s is the scale factor and "a" is the number of centimeters which 5 meters

First, we need to find the scale factor. 50 meters would be s times greater than 2 centimeters. Find s by first converting meters into centimeters
50m=5000cm. 5000cm=2cm*s, so s = 2500
5m=a*2500, a=0.002 meters, and 0.002 meters is equal to 0.2 centimeters.

Strategy 2:
the ratio of the scale drawing to real life will always stay the same, so
2 cm / 50 meters = x / 5 meters, and cross multiply to get
x cm* 50 m = 2 cm * 5 m, so
x cm * 10 = 2 cm
x cm = 2/10 cm
x cm = 0.2 cm

Strategy 3:
Notice that 5 meters is 10 times smaller than 50 meters, so on the scale drawing, we are looking for a number 10 times smaller than 2 centimeters, so  2/10=0.2 cm

A scuba diver returning to the surface swims to move up quickly, then waits a few meters below the surface to avoid pressure iss
Juliette [100K]

Given:

The function f represents the diver's distance from sea level over time, in seconds.

f(x)=\begin{cases}3x+1 & \text{ if } -9

To find:

The correct statement for the domain.

Solution:

Domain is the set of input values for which the function is defined.

Here, x values are the input values and they represent time intervals on which the function is defined

Here, the possible intervals for x are -9.

Domain=(-9,-2]\cup (-2,1]\cup (1,7)

Domain=(-9,7)

Therefore, the domain is the time interval (−9, 7). Hence the correct option is A.

Help please! my teacher wants us to show how we got our answer
Mila [183]

Direct variation is when \dfrac{y}{x} is the same for each coordinate.

Indirect variation is when x · y is the same for each coordinate.

11. Answer:  Direct Variation

<u>Step-by-step explanation:</u>

\begin {array}{c||c|c|c|c|c}x&12&18&23&29&34\\y&132&198&253&319&374\\\\\dfrac{y}{x}&\dfrac{132}{12}=11&\dfrac{198}{18}=11&\dfrac{253}{23}=11&\dfrac{319}{29}=11&\dfrac{374}{34}=11\\\end{array} \\\\\\\text{The coordinates x and y show a direct variation.}

12. Answer: Indirect Variation

<u>Step-by-step explanation:</u>

\begin {array}{c||c|c|c|c|c}x&4&6&8&8.4&12\\y&21&14&10.5&10&7\\x\cdot y&4\cdot 21=84&6\cdot 14=84&8\cdot 10.5=84&8.4\cdot 10=84&12\cdot 7=84\\\end{array} \\\\\\\text{The coordinates x and y show an indirect variation.}

Can someone help me with this.
Ber [7]

Answer:

C

Step-by-step explanation:

The secant- secant angle SPR is half the difference of the intercepted arcs, that is

55° = \frac{1}{2} (RS - QT ) ← multiply both sides by 2

110° = RS - QT = RS - 50° ( add 50° to both sides )

160° = RS → C
