Can you please explain this to me and answer

Answers

1)73 degrees
all the angles of a triangle add up to 180 degrees.
23+84= 107
180-107=73

2) 28 degrees
110+42= 152
180-152= 28

Explanation:

All sides in a triangle is equal to 180°
So whenever given two sides only, add them up, and subtract from 180. That will give you the missing sides length.
So 23 + 84 = 107
180 - 107 = 73
The missing side of the triangle is equal to 73°.

110 + 42 = 152
152 - 180 = 28°
The missing side of the triangle is equal to 28°.

Another example is:
100°, 40°
Front the missing side in this triangle.
100 + 40 = 140°
180 - 140 = 40°
The missing length is 40°

Heather deposits $7000 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 3 years?

Answers

Answer:

year after 3 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $7000.00.

r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.

t is the time involved, 3....year(s) time periods.

So, t is 3....year time periods.

To find the simple interest, we multiply 7000 × 0.02 × 3 to get that:

The interest is: $420.00

Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),

or 7000.00 + 420.00 = 7420.00. For example:

If you borrowed the $7000.00, you would now owe $7420.00

If you loaned someone $7000.00, you would now be due $7420.00

If owned something, like a $7000.00 bond, it would be worth $7420.00 now.

420 dollars in 3 years

The school did reach the goal because if you add the games, concessions and donations you get $1232 and if you subtract 28 from it you get $1204 and if you subtract 75 from that you get $1129.

yes, they did reach their goal.

Start by adding 650, 530, and 52 because those are all the money made and received (the income). Then there are the expenses that you have to subtract due to the fact that they're losing money. So from adding all the income you get 1232 and then when you subtract your expenses you get 1129 which is a 29 dollar difference. (i hope this helped :D)

If a radius of a sphere is divided by 2, will the surface area be divided by 2?

Answers

If r is the radius of a sphere its surface area = 4(pi)r^2.

If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.

So the surface area becomes 4-fold or the increase in surface area is 300%.

2.) y=kx is the direct variation formula. Inserting the information and variables from this scenario we get h = kn.

12 = k*(10) First solve for 'k', the constant of proportionality by dividing by 10.

1.2 = k

Next write the equation using this k and the h & n.

h = 1.2*n

Now we want to find the height if we have 24 books so plug 24 in for n.

h = 1.2 * 24

h = 28.8 inches
