She spins 20 times:
20 * 0.2 = 4
So she should expect getting 4 twos.

Answer:
y = -1/2x - 1/2
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
y = -1/2x + 3/7
Point (-1, 0)
Step 2: Find parallel line
<em>Parallel lines have the same slope as the original but different y-intercepts.</em>
<em>m</em> = -1/2
y = -1/2x + b
0 = -1/2(-1) + b
0 = 1/2 + b
b = -1/2
Step 3: Write parallel line
y = -1/2x - 1/2
Answer:
400 < m< 430 kg
Step-by-step explanation:
the mass of horse is 429 kg
estimated to the nearest hundred is 400 kg
estimated to the nearest tens is 430 kg
thus the value of m mass lies between 400 to 430
therefore
400 < m< 430 kg
19.25 (tax)
294.25 (total price)
135.75 (money left)
REASONING:
In this word problem it says Anna has 430 dollars. The phone costs 275 dollars. It also says that when she buys the phone, she will have to pay a tax of 7%.
To find how much tax she will pay, we must do [275] x [0.07]
After inputting this into a calculator, you will get 19.25 (tax)
To find the total price, all you have to do is add 19.25 to 275. When you do this, you will get 294.25 dollars (total price)
To find how much money she has left,
430-294.25=135.75 (money left)
