Mathematics
1 answer:
Maru [420]3 years ago
7 0
Given:
Principal = 17,000
rate = 10.7%
term = x/360
interest = 1,121.72

Interest = Principal * rate * term
1,121.72 = 17,000 * .107 * x/360
1,121.72 = 1,819x / 360
1,121.72 * 360 = 1,819x
403,632 / 1,819 = x
221.90 = x

Lauren Michelle will have to wait 222 days for her investment to earn $1,121.72

Given:
Principal = x
rate = 9%
term = 10 months
interest = 1,687.50

Interest = Principal * rate * term
1,687.50 = x * 0.09 * 10/12
1,687.50 = x * 0.075
1,687.50 / 0.075 = x
22,500 = x

The amount Sandra Leatherwood invested was $22,500.

Which of the tables represent a function??<br>please help me! asap!​
Katyanochek1 [597]
The answer is table C
For anything to be a function, it cannot have two pairs as my teacher taught me!
For example, let’s take the number 4
Let’s say 4 can take a friend to the fair!
4 decided to take 5 (4,5)
4 CANNOT take anyone else but 5
4 is allowed to take as many 5’s as they want but cannot take any other number
Let’s set up a table

X. Y
4. 5
4. 5
4. 5
This is a function

If the table changed:
X. Y.
4. 5
4. 5
4. 6
This will not be a function
I hope this helps!

A band leader randomly selects 2 students out of 80 band members. If you and your brother are both band members, what is the pro
drek231 [11]
The first time the band leader selects one member, the probability that either you or your brother gets selected would be 2 out of 80 or in fraction 2/80. Now, once one of you gets chosen, for the next selection, there are only 79 members left and the probability that the remaining one (between you and your brother) gets selected after is 1/79. So, if you are both to be selected, the combined probability for that to happen will be (2/80)(1/79) = 1/3160. Therefore, the answer is 1/3160<span>.</span>

David has a loyalty card good for a 19% discount at his local hardware store. What would his total in dollars and cents be, afte
Elina [12.6K]

Discounts are used to reduce the original price of an item.

David will pay $25 and 92 cents for an item of $32, before tax

The discount (d) is given as:

d =19\%

The price (p) of the item is given as:

p = \$32

So, the amount (A) paid before tax is calculated using:

A = p \times (1 - d)

Substitute known values

A = \$32 \times (1 - 19\%)

Express percentage as decimal

A = \$32 \times (1 - 0.19)

Subtract 0.19 from 1

A = \$32 \times 0.81

Multiply 32 and 0.81

A = \$25.92

Hence, David will pay $25 and 92 cents for an item of $32, before tax

4688-3) -30X-5 CX-5)
pshichka [43]

Answer:

x = 13/3

Step-by-step explanation:

4(8x-3) - 30x = 5(x-5)

Distribute

32x - 12 - 30x  = 5x -25

Combine like terms

2x -12 = 5x-25

Subtract 2x from each side

2x-12-2x = 5x-2x -25

-12 = 3x-25

Add 25 to each side

-12+25 = 3x-25+25

13 = 3x

Divide each side by 3

13/3 = x
