Dan invests £1200 into his bank account.
He receives 5% per year compound interest.
How much will Dan have after 5 years

Answers

Well 5% of £1200 would be £60 which would be equal to 1 year and then you multiply that by 5 to find 5 years which is 300 and then you add the £300 onto the starting amount so £1200 + £300 = £1500

Answer:

answer is 3 11/12

Step-by-step explanation:

1 4/6 =10/6

2 1/4=9/4

when adding fractions that are do not share a common denominatour you have to find a common multiple

which in this case is 12

so 9/4 timesed the top and the bottom by 3 gives you 27/12

and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)

4. What is the volume of the cone shown below?
Round to the nearest tenth.
5 ft.
d = 2 ft.

Answers

Answer:

5.2 cubic ft

Step-by-step explanation:

took the test

The volume of given cone is 5.23 cubic feet.

What is volume?

Volume is the measure of the capacity that an object holds.

Formula for the volume of cone

[tex]v = \frac{1}{3} \pi r^{2} h[/tex]

where,

v is the volume of cone

r is the radius of cone

h is the height of cone

According to the question we have

Diameter of cone is 2ft

⇒ radius of the cone = [tex]\frac{2}{2} = 1 feet[/tex]

Height of the cone is 5ft.

Therefore,

The volume of the cone  = [tex]\frac{1}{3}(1)\pi( 1)^{2} (5)[/tex]

Volume of cone = [tex]\frac{1}{3} (3.14)(1)(5) = 5.23 cubic feet[/tex]

Hence, hence the volume of given cone is 5.23 cubic feet.

Convert the equation 9x + y = 4 Into slope-intercept form. Make sure to simplify if possible.​

Answers

Answer:

x = -1/9y + 4/9

Step-by-step explanation:

9x+y=4

Step 1: Add -y to both sides.

9x+y+−y=4+−y

9x=−y+4

The required equation in slope intercept form is given by y = -9x + 4.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees

What is the intercept in the equation?

In the equation intercept is the value of the linear function where either of the variables is zero.

here,
The slope intercept of the line is given as,
y = mx + c,
Where m = slope of the line and c = y-intercept of the line,

Given equation of line 9x + y = 4
Rearrange the equation,
9x + y = 4
y = -9x + 4

Thus, the required equation in slope intercept form is given by y = -9x + 4.

hey, do you guys like my speech!??? I wrote it and if you have any pointers on how to make is better :)???Classical Music is the type of music that is very serious or conventional, which follows long-established principles different from jazz. I believe it is very important for almost everyone, as it helps people feel relaxed and rejuvenate their spirits. It helps in experiencing a huge gradual range of emotions, such as despair, love, happiness, and even sadness. This specific type of music is important as it serves various purposes; it helps people in getting away from all the confusion in life and focus on lifes goals, such as a job opportunity, or just an accomplishment. This fascinating type of music helps put me into a zone to just completely focus on whatever subject I need to. I believe Classical Music is something most people find beautiful, and I think others may not even understand. My thoughts to do this speech immediately went to classical music and how I find it not just beautiful, but emotionally sole-shatteringly sometimes. Classical music, I believe, has the power of moving someone emotionally without speaking a word, it isn't just noises thrown together, it's something that a person has learned to create so carefully. Each note is put together to make the perfect piece. It can feature one instrument or multiple and can be replicated so that it's never lost.There is a world-renowned composer, which I am sure all of you know. His name is Ludwig van Beethoven. Beethoven was a German composer and pianist, born December 1770, Bonn, Germany. Beethoven was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western classical music. His works span the transition from the classical period to the romantic era in classical music. They are famous for their great strength to empower you in his pieces of music. My most personal favorite is Beethoven Moonlight Sonata - Piano Sonata No. 14, this piece was designed to let you focus. Beethoven music you can listen to for hours, they are absolutely fascinating to hear and almost feel how wonderful it is. Classical music expresses the deepest thoughts of our civilization. Composers paint an image of the society and times within which they lived. you'll be able to expertise the greatness and achievements of another generation through its music. If we tend to dont die this unbelievable thread of artistic living history that binds the United States of America one generation to the opposite then we diminish all of the humanity that came before us and definitely leave an open hole for the future. we tend to bear in mind however necessary the musical genre is in a very world that perpetually appears as it stands on the precipice of a scarily dark chasm. Music continues to bridge the nice divide between cultures and countries. It will bring hope for peace within the darkest of times.Classical music has its own noble history just like the remainder of the music types. each culture and tradition has its own type of classical music that competes with the help of various instruments for instance Indians, Chinese, Arabs, and Europeans had their own traditions for classical music. The genre may be a broad, somewhat inexact term, pertaining to music produced, or frozen within the traditions of art, religion, and concert music. Music is classical if it includes a number of the subsequent features: a learned tradition, support from the church or government, or larger cultural capital. genre is additionally delineated as complex, lasting, transcendent, and abstract.Thank you. help solve, thank you much yall PLEASE HELP ASAP What country is shaded on map Why did Kobe Bryant want Dear Basketball to have a hand drawn element?A.
