In January, you deposit $16 in your checking account. Each month, you deposit $15 more than you did the month before. How much money do you deposit in October?
Answer:
$151Step-by-step explanation:
This problem is about a arithmetic sequence, which is obtained by summing a term which is called "difference". In this case, we need to find the tenth term of the arithmetic sequence, because that's the term assigned for October. The formula of an arithmetic sequence is
[tex]a_{n}=a_{1}+(n-1)d[/tex]
Where:
[tex]n=10\\a_{1}=16\\d=15[/tex]
Replacing values, we have
[tex]a_{10}=16+(10-1)15=151[/tex]
Therefore, on October you will have $151 if you deposit $15 more each month, beginning with $16.
What is the value of a, if a2 – 64 = 0 and a > 0? A) 0 B) 4 C) 8 D) 16
Answer:
C) 8
Step-by-step explanation:
Let's solve for:
[tex]a^2 -64=0\\\\a>0[/tex]
Add 64 to both sides:
[tex]a^2-64+64=0+64\\\\a^2=64[/tex]
Take the square root of both sides
[tex]\sqrt{a^2} = \sqrt{64} \\\\a=\pm 8[/tex]
Therefore, we got two solutions:
[tex]a=8\\\\or\\\\a=-8[/tex]
However, since:
[tex]a>0[/tex]
The only solution is:
[tex]a=8[/tex]

How many pairs of parallel faces are shown?
3
5
4
6
Answer:
The answer is 3 pairs.
Step-by-step explanation:
The flat surfaces that meet at edges are called faces.
The given figure is a cube.
The cube possess six square faces with three meeting at each vertex. In total it has 6 faces, 12 edges, and 8 vertices. Its six faces are arranged in three sets of two parallel faces.
So, there are 3 pairs of parallel faces in a cube.

The dance instructor asks his class for three volunteers to show some new moves. There are twenty people in class and everyone is silent. One girl, Janie looks around the room to see if anyone is going to volunteer first. Then maybe she won't have to volunteer if someone else does. Which term describes why Janie didn't want to volunteer? bystander effect diffusion of responsibility social facilitation conformity
The term that describes why Janie didn't want to volunteer is probably the diffusion of responsibility. I think this is the answer ( and this is the answer I put on my quiz ) because the responsibility does not have to belong to Janie since there are nineteen other students that can volunteer.
Answer: Diffusion of responsibility

A lighthouse cast a shadow that is 36 meters long at the same time , a person who is 1.5 meter tall casts a shadow that is 4.5 meters long . Write and solve a proportion to find the height of the lighthouse
To find the height of the lighthouse, set up a proportion using the lengths of the shadows and solve for h. The height of the lighthouse is 12 meters.
Explanation:To find the height of the lighthouse, we can set up a proportion based on the lengths of the shadows. Let h be the height of the lighthouse. The proportion is:
(h / 36) = (1.5 / 4.5)
Now, we can cross multiply and solve for h:
h = (1.5 / 4.5) * 36
h = 12 meters

Let f(x)=6x. The graph of f(x) is transformed into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 units up.
What is the equation for g(x)?
Enter your answer in the box.

The correct answers are actually : 2x+2 these are correct bc i just took the test.
Hope this helps.
The graph of f(x) after transforming into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 units up is g(x) = 2x + 2.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
The graph of f(x) = 6x
Vertical compression = 1/3.
Translation = 2 units up.
If there is a vertical compression of 1/3 on the graph f(x).
The graph of f(x) = 6x transformed as g(x) = 1/3 x 6x = 2x
Now,
If the graph g(x) 2x has a translation of 2 units up we get,
g(x) = 2x + 2
g(x) = 2(x + 1)
Thus,
The graph of f(x) after transforming into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 units up is g(x) = 2x + 2.

A marathon is 26 miles 385 yards long . That is about what 1.4 x10 feet how many feet long is half a marathon
I believe that the correct measurement in feet is 1.4 x 10^5 feet. You forgot to include the ^5.
So since that is the measurement of 1 marathon, therefore half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
Final answer:
Half a marathon is 69,168 feet in length. To calculate the runner's time for a full marathon at an average speed of 9.5 mi/h, divide the distance (26.2 miles) by the speed, resulting in approximately 2.76 hours or about 2 hours and 45 minutes.
Explanation:
To find the length of half a marathon in feet, we first need to know the length of a full marathon in feet then divide that by 2. Since one marathon is approximately 26.2 miles, we first need to convert miles to feet. There are 5,280 feet in one mile. So, for a full marathon:
26.2 miles × 5,280 feet/mile = 138,336 feet for a full marathon.
Therefore, half a marathon would be:
138,336 feet ÷ 2 = 69,168 feet for half a marathon.
Next, let's look at the question about the marathon runner's time. If a runner averages 9.5 mi/h over a full marathon of 26.2 miles, we can calculate the time taken to run this distance. Time is distance divided by speed, so:
26.2 miles ÷ 9.5 mi/h = approximately 2.76 hours,
which can be converted to minutes: 2.76 hours × 60 minutes/hour = approximately 165.6 minutes or about 2 hours and 45 minutes.

The height of a building in a scale drawing is 9cm.The scale is 1:600.Explain how you would use the scale to find the actual height of the building.
The actual height of the building is 54 meters.
The actual height of the building is calculated by multiplying the scale drawing height by the scale factor.
Given that the scale is 1:600, this means that 1 centimeter on the drawing represents 600 centimeters in reality.
Therefore, to find the actual height of the building, one would multiply the height of the building on the scale drawing (9 cm) by the scale factor (600).
Using the scale, the actual height H of the building can be determined as follows:
[tex]\[ H = \text{scale drawing height} \times \text{scale factor} \] \[ H = 9 \, \text{cm} \times 600 \] \[ H = 5400 \, \text{cm} \][/tex]
To convert centimeters to meters, since there are 100 centimeters in a meter, we divide by 100:
[tex]\[ H = \frac{5400 \, \text{cm}}{100} \] \[ H = 54 \, \text{m} \][/tex]
Thus, the actual height of the building is 54 meters.

A baby weighed 7.25 lb at birth at the end of 8 months , the baby weighed 2 1/2 times its birth weight. how many pounds did the baby weigh at the end of 8 month ?
Answer:
The weight of baby at the end of 8 month is 18.125 lb.
Step-by-step explanation:
Given information:
The weight of baby at birth = 7.25 lb
At the end of 8 months, the baby weighed [tex]2\frac{1}{2}[/tex] times its birth weight.
We need to find the weight of baby at the end of 8 month.
[tex]2\frac{1}{2}=\frac{4+1}{2}=\frac{5}{2}[/tex]
The weight of baby at the end of 8 month is 5/2 times of its initial weight.
[tex]\text{Total weight}=7.25\times \frac{5}{2}[/tex]
[tex]\text{Total weight}=18.125[/tex]
Therefore the weight of baby at the end of 8 month is 18.125 lb.
