3.6 + 6.1 = 9.7

Lets go through your choices to see which one is correct

10^3 = 1000

10^6 = 1,000,000 (So, B & D aren't your answers that you're looking for

Now we have to choose from A & C.

C. isnt your answer because it equals 97,000

Option A. 9.7✖10^3 would most likely be your answer!

a car travels along a straight road heading east for one hour, then traveling for 30 minutes on another road that leads northeas
My name is Ann [436]

Answer:

55.96 miles

Step-by-step explanation:

Distance = Speed X time

Car first moved east for 1 hr , distance = 40 x 1 = 40 miles

Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles

From trigonometry,

sin 45 = \frac{y}{20} ; y = 20 sin 45 ; y= 14.14 miles

cos 45 = \frac{x}{20} ; x = 20 cos 45 ; x = 14.14 miles

using Pythagoras theorem;

z^{2} = y^{2} + (40+x)^{2}

    = 14.14^{2} + (40+14.14)^{2}

     = 3131.08

z^{2} = \sqrt{3131.08}

z = 55.96 miles

The probability the next customer pays using a debit card based on the last three weeks is 30% or 0.3.

<h3>What is a probability?</h3>

This is the chance or likelood for an event to occur. For example, if in a city it has snowed every year on December 25th, there is a high probability it will snow this year and in the next years.

<h3>How to calcuate the probability?</h3>

Total of a specific outcome/ total of outcomes

Based on this, let's calculate the probability the next customer pays using the debit card:

  • Total that pay with debit card: 21 customers
  • Total of customers: 70 customers
  • 21/ 70 =0.3 or 30%
