ILL GIVE BRAINLIEST !!!1 A student writes an incorrect step while checking if the sum of the measures of the two remote interior

angles of triangle ABC below is equal to the measure of the exterior angle.
Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 2: m∠w − m∠z = 90 degrees (corresponding angles)
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w

In which step did the student first make a mistake and how can it be corrected?

Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of corresponding angles)

Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)

Step 1; it should be m∠x + m∠y + m∠z = 90 degrees (corresponding angles)

Step 2; it should be m∠w + m∠z = 90 degrees (alternate exterior angle)

Answer:

P(milk) = 7/18

P(not milk) = 11/18

Step-by-step explanation:

The bag contains 7 milk and 11 dark chocolates. That means that there are a total of; 7 + 11 = 18 sweets in the bag.

So, when a sweet is selected at random, probability that the sweet is milk is;

P(milk) = number of milk sweets/total number of sweets = 7/18

Probability it is not milk is;

P(not milk) = number that's not milk/total number of sweets = 11/18

A manufacturer makes ball bearings out of motel steel. it takes 5.24 cubic centimeters of molten steel to make ball bearings tha
katrin2010 [14]

Using volume of ball bearings, a manufacturer makes 10 ball bearings from 5.2 cm³ of molten steel to make ball bearings that each have a diameter of 1 centimeter.

According to the question,

It takes 5.24 cubic centimeters of molten steel to make ball bearings that each have a diameter of 1 centimeter.

Radius = 1/2 = 0.5 cm

volume V of one ball bearing is: V=(4/3)*π*r³

= 4/3 * π * (0.5)³

=0.524 cm³

In order to find number of ball bearings out of molten steel only if we divide the volume of steel by the volume of the ball bearing

5.24/0.524=10.

Hence, using volume of ball bearings, a manufacturer makes 10 ball bearings from 5.2 cm³ of molten steel to make ball bearings that each have a diameter of 1 centimeter.

Mark estimated that the drive would take 3,000 minutes. It ended up taking 2 days. Did the drive take longer or shorter than he
Arlecino [84]

Answer:

The driver took shorter than estimated

It took shorter by 2 hours( 120

minutes)

Step-by-step explanation:

Firstly we want to know if the drive took longer or shorter

By 2 days, the number of hours will be 2 * 24 = 48 hours ( recall 24 hours = 1 day

now , since 60 minutes give one hour, then 48 hours will me 60 * 48 = 2,880 hours

This is less than 3,000 hours

By how much?

Simply subtract the value of minutes in 48 hours from 3,000 = 3000-2880 = 120 minutes ( or two hours)
