The amount of time is takes dora to commute to work is always within 5 minutes of the average number of minutes the commute takes. If the average ammount of time she takes to get to work is 45 minutes
Answer:
The average time to commute to work is 25 minutes.
Step-by-step explanation:
If average time for Dora to commute to work is 5 mins. If she takes 45 mins to get to work then her overall average time to commute to work will change as the average consists of 2 or more figures. The average time to commute to work is 25 mins ((5+45)/2). The average of 5 mins and 45 mins is 25 mins. This is the overall average time she takes to commute to her work.

Answer:
140, 60
Step-by-step explanation:
15x+5 + < CDB =180 line form an 180 angle
180-80-6x-6 = < CDB sum of angles in a triangle is 180
substitute < CDB from second to first
15x+5+180 -80-6x-6 =180
combine like terms
9x -81 =0
x=81/9=9
so angle YDC = 15*9+5 = 140 degrees
and angle DBC = 6*9+6= 60 degrees

Find the measure of the indicated angle to the nearest degree.
A. 36
B. 30
C. 54
D. 60
Answer:
54 degrees
Step-by-step explanation:
This is trigonometry. So we are given the adjacent leg and hypotenuse. So we can use cosine(cah from soh cah toa)
We will have to use the inverse of the trig ratios.
Remember!
cos^-1 is not 1/cos(that is sec)
cos^-1(27/46)
acos(27/46)
54.0586701 and so on
Round to nearest degree 54

Liz is making cookies for the annual bake sale at her
school. Each batch of cookies takes 2 3/4 cups of flour. If Liz
needs to makes 6 batches, how many cups of flour will
she need for all six batches?
Answer:
9
Step-by-step explanation:
It is very simple, 3/4 * 2 = 1.5
If we take 1.5 and multiply it by the amount of batches being made (6), we will have our answer.
1.5*6 = 9, so there we have our answer.
Hope this helps!

3y−3x=21 Put the following equation of a line into slope-intercept form, simplifying all fractions.
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c )
Given
3y - 3x = 21 ( add 3x to both sides )
3y = 3x + 21 ( divide all terms by 3 )
y = x + 7 ← in slope- intercept form
Hernando ate 2/8 of a pizza for a dinner. he gave his 6 friends the rest of the pizza, and told them to share equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below.
6/8 divided by 6= (6 divided by 6)/8= 1/8
he concluded that each person received 1/8 of the whole pizza. Are Hernando's calculations correct?
O yes they are correct. Hernando divided 6 by 6
O yes they are correct. Hernando divided 2/8 by 6
O No they are not correct. Hernando should have multiplied by 6, not divided by 6
O No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.
Answer: yes correct . hernando 6 by 6
Step-by-step explanation:
Answer:
yes they are correct. Hernando divided 6 by 6
Step-by-step explanation:
Hernando ate 2/8 of a pizza for a dinner.
he gave his 6 friends the rest of the pizza, and told them to share equally.
Rest pizza portion=1-2/8
=6/8
6/8 pizza divided into 6 person
6/8÷6
1/8
So 1/8 portion get each person
So the option a is correct
yes they are correct. Hernando divided 6 by 6

John writes the proof below to show that the sum of the angles in a triangle is equal to 180 degrees
Which would John NOT need to use in his proof?
A.The sum of the angles on ore side of a straight line is 180
B. If a statement about a is true and a = b statement formed by replacing a with b is also true.
C.When two parallel lines are cut by a transversal, the resulting alternate interior angles are congruent.
D. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent
Answer: A
Step-by-step explanation:
The proof that is not needed John's proof is When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent
The following proof are needed.
When two parallel lines are cut by a transversal, the resulting alternate interior angles are congruent. This is why ∠4≅∠1 and ∠5≅∠3. The sum of the angles on one side of a straight line is 180. That is why m∠4 + m∠2 + m∠5 = 180°If a statement about a is true and a = b statement formed by replacing a with b is also true.m∠4 + m∠2 + m∠5 = 180° (sum of angles on a straight line)
∠4≅∠1 and ∠5≅∠3 (alternate interior angles)
Therefore,
∠1 can replace ∠4 and ∠3 can replace ∠5
m∠1 + m∠2 + m∠3 = 180°
Therefore, When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent is not needed.

You want to know the opinions of drivers with valid licenses across America on the issue of establishing a law that requires individuals to take and pass another driver's test at the age of 65 to determine whether they may retain their license. You obtain a list of all licensed drivers and mail a survey to a random sample of 10,000 drivers. Of those, 6,457 responded and 46% say they favor the test. Which of the following statements is true? (5 points)
A. Because random sampling is used, we can feel confident that the percentage of all
drivers with a valid license who say they favor the test is close to 46%.
B. The results of this survey may be affected by nonresponse bias.
C. We cannot trust these results because the survey was mailed. Only survey results
from face-to-face interviews are considered valid.
D. Because more than half of those who were mailed the survey actually responded,
we can feel fairly confident that the actual percentage of all drivers with a valid
license who say they favor another test is close to 46%.
