Look at the figure. What is the next step in this construction of a line parallel to AC passing through point B.
A. use a protractor to measure ∠BAC
B. Draw a line through point B that intersects arc 2.
C. Measure the distance between AB and AC along arc 1 with a ruler.
D. Measure the distance between AB and AC along arc 1 with a compass.
Answer:
Option A is correct
Step-by-step explanation:
In the given figure to draw the parallel line to AC passing through B we have to tell the next step.
As lines AC and AB given and we know if lines are parallel then alternate angles are equal.
Hence, if line through B parallel to AC drawn then alternate angles ∠BAC and ∠ABD equal.
∴ To draw parallel lines our next step is to use a protractor to measure ∠BAC so that the same angle through B is drawn results in equal alternate interior angles.
Hence, Option A is correct.

Jones is the chairman of a committee. in how many ways can a committee of 5 be chosen from 10 people given that jones must be one of them?
Final answer:
A committee of 5 can be chosen in 126 different ways from 10 people if Jones must be one of them, by using the combination formula C(9, 4) to choose the remaining four committee members from the other nine people.
Explanation:
To determine in how many ways a committee of 5 can be chosen from 10 people given that Jones must be one of them, we need to apply the concept of combinations in probability and combinatorics. Since Jones must be on the committee, we are actually choosing the remaining 4 members from the remaining 9 people.
The number of ways to choose 4 people out of 9 is calculated using the combination formula, which is:
C(n, k) = n! / (k!(n - k)!), where n is the total number of items, k is the number of items to choose, and '!' denotes factorial.
Applying this to our scenario:
C(9, 4) = 9! / (4! * (9 - 4)!) = 126
Therefore, there are 126 different ways to form the committee if Jones is already chosen as one member.

Mr. Chavez spent $199.99 for a new smart phone, 3
Mr. Chavez spent $299.97 altogether. The estimated total matches approximately with the calculated total, confirming the accuracy of our answer.
To find the total amount Mr. Chavez spent, we need to add the costs of the smartphone, carrying case, and accessories.
Total amount = |-199.99| + |-39.99| + |-59.99|
Now, let's evaluate each absolute value:
|-199.99| = 199.99
|-39.99| = 39.99
|-59.99| = 59.99
Now, let's add them together:
Total amount = 199.99 + 39.99 + 59.99
Total amount = 299.97
So, Mr. Chavez spent $299.97 altogether.
Now, let's check the answer using estimation:
Round each amount to the nearest ten:
- $199.99 is approximately $200.00
- $39.99 is approximately $40.00
- $59.99 is approximately $60.00
Now, let's add them together:
Total estimation = $200.00 + $40.00 + $60.00
Total estimation = $300.00
The estimated total matches closely with the calculated total, confirming the accuracy of our answer.
The complete question is:
Mr. Chavez spent $199.99 for a new smart phone,$39 .99 on a carrying case, and $59.99 on accessories. The expression |-199.99|+|-39.99|+|-59.99| represents the total amount that Mr. Chavez spent. How much did Mr. Chavez spend altogether? Check your answer using estimation.

Use the drop-down menus to complete each statement to show why √21 is between 4 and 5.
Answer:
To show: [tex]\sqrt{21}[/tex] is between 4 and 5
We know:
21 is lies between two consecutive integer i.e, 16 and 25
We can write this as:
[tex]16 < 21 < 25[/tex]
or
[tex]\sqrt{16} <\sqrt{21}<\sqrt{25}[/tex]
Simplify:
[tex]4 < \sqrt{21} < 5[/tex]
⇒[tex]\sqrt{21}[/tex] lies between 4 and 5.
Therefore, [tex]\sqrt{21}[/tex] is between [tex]\sqrt{16}[/tex] and [tex]\sqrt{25}[/tex] this means [tex]\sqrt{21}[/tex] lies between 4 and 5.
Answer:
We know that
[tex]16<21<25[/tex]
Because, 16 is less than 21 and 25 is more than 21.
Now, if we apply a square root to each part, we would have
[tex]\sqrt{16} < \sqrt{21}<\sqrt{25}[/tex]
Then, we solve each square root, except the square root of 21, because it doesn't have an exact result
[tex]4<\sqrt{21}<5[/tex], because [tex]\sqrt{16}=4[/tex] and [tex]\sqrt{25}=5[/tex]
So, basically, the reason why [tex]\sqrt{21}[/tex] is between 4 and 5 is beacuse 21 is between 16 and 25. Then, when you apply square roots to each part, you would find that the square root of 21 is between 4 and 5. That's the reason, the position.
Joe and Mary each pay the same price for a T-shirt. Before they buy it, Mary has $\$ 2$ more than Joe. To buy the T-shirt, Joe spends $ \$1 $ less than $\frac{2}{5}$ of his money, and Mary spends $\frac{1}{3}$ of her money. What was the total amount of money Joe and Mary originally had altogether?
Answer:
52
Step-by-step explanation:
Suppose Joe had $J$ dollars to start with. Then Mary had $J + 2$ dollars. Since they both spent the same amount on their shirts, $\frac{2}{5} J - 1 = \frac{1}{3} (J + 2)$. Distributing, we get $\frac{2}{5} J - 1 = \frac{1}{3}J + \frac{2}{3}$. Isolating $J$ on the left side, $\frac{1}{15}J = \frac{5}{3}$. Therefore, $J = 25$. Thus, their original total amount of money was $J + (J + 2) = \boxed{52}$ dollars.

This chart shows the total average monthly cost of medical insurance benefits for employees working in the private sector in march 2006. for single coverage, the cost is $322.77, and for family coverage, it is $889.26. if an employee makes $10 per hour (after withholdings) and has to pay the full cost of single coverage medical insurance, about how many hours will he or she have to work each month simply to pay for the cost of the medical insurance
Final answer:
the employee would need to work approximately 32.3 hours per month to pay for their health insurance.
Explanation:
The student has inquired about the number of hours they would need to work each month to pay for the cost of single coverage medical insurance.
Given that the insurance costs $322.77 per month and the employee earns $10 per hour, we can find the number of hours required by dividing the total cost of the insurance by the hourly wage.
To calculate:
Hours required = Total cost of insurance ÷ Hourly wage
Hours required = $322.77 ÷ $10 = 32.277
Therefore, the employee would need to work approximately 32.3 hours per month (rounding to the nearest tenth of an hour) to pay for their health insurance.
In triangle KLM LM = 7 and angle k equals 45 Find KL.
In this problem, the student can use the properties of a 45°-45°-90° triangle to determine that the hypotenuse KL is 7 * √2 which is approximately equal to 9.9.
Explanation:In a triangle where you know one angle (45°) and one side (7 units) across from the right angle, it is a typical example of a situation where trigonometry can be used. In this case, you're dealing with a 45°-45°-90° triangle, also known as an isosceles right triangle. In such a triangle, the sides are in a specific ratio. The sides opposite the 45° angles are the same length (let's call it 'a'), and the hypotenuse is a√2.
Given that LM = 7 and angle K is 45°, triangle KLM is therefore an isosceles right triangle and KL (the hypotenuse) is equal to LM multiplied by √2. So, KL = 7 * √2 which approximately equals to 9.9.

Thomas buys a cardboard sheet that is 8 by 12 inches. Let x be the side length of each cutout. Create an equation for the volume of the box, find the zeroes, and sketch the graph of the function.
Answer:
Step-by-step explanation:
Any equation that is equivalent to V = x(12 - 2x)(8 - 2x) is accepted. Any graph that is similar to the graph of the function is accepted.
Sample Student Response:
The box is a cube, so the volume is the length × width × height. The height is the side length of the cardboard, which is x.
The length is the original length minus two side lengths of the cutout, so the length is 12 - 2x.
Similarly, the width is the original width minus two side lengths of the cutout, so the width is 8 - 2x.

Taylor and Blair are driving away from each other in opposite directions. If Blairs speed is 70mph and Taylors speed is 80mph, how many hours will it be before the two are 225 miles apart?
It will take 1.5 hours (or 1 hour and 30 minutes) before Taylor and Blair are 225 miles apart.
To find out how many hours it will be before Taylor and Blair are 225 miles apart, we can set up an equation based on the distance they travel.
Since they are driving away from each other in opposite directions, their distances add up to the total distance they will be apart.
Let t be the number of hours it takes for them to be 225 miles apart.
Distance traveled by Blair = Blair's speed * time (d = r * t)
Distance traveled by Taylor = Taylor's speed * time (d = r * t)
The total distance they will be apart is 225 miles:
Blair's distance + Taylor's distance = 225 miles
(70 mph * t) + (80 mph * t) = 225 miles
Now, solve for t:
70t + 80t = 225
150t = 225
t = 225 / 150
t = 1.5
So, it will take 1.5 hours (or 1 hour and 30 minutes) before Taylor and Blair are 225 miles apart.
