Answer:

The expression that gives the total of Lee's score = 275+70-50

Step-by-step explanation:

Before the game ends, Lee answers a 275-point question correctly, a 70-point question correctly, and a 50-point question incorrectly.

Lee's final score can be given by:

275+70-50 = 295 points

The expression that gives the total of Lee's score = 275+70-50

He would have 345 points UNLESS the 50 points he got wrong were subtracted from his score. Then his score would be 295.


275+70=345
 Now if the 50 points were subtracted it would be 275+70=345-50=295

A student has a savings account earning 3% simple interest. She must pay $1200 for first-semester tuition by September 1 and $12
Bingel [31]

Using simple interest, it is found that she needs to earn $2,391.07 during the summer.

<h3>Simple Interest</h3>

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

A(t) = A(0)(1 + rt)

In which:

  • A(0) is the initial amount.
  • r is the interest rate, as a decimal.

For this problem, the objective is to have <u>$1200 in 3 months = 0.25 years</u>, hence the parameters are given as follows:

A(0.25) = 1200, t = 0.25, r = 0.03.

Hence we have to solve for A(0):

A(0)(1 + 0.03 x 0.25) = 1200

A(0) = 1200/(1 + 0.03 x 0.25)

A(0) = $1,191.07.

She also needs to earn $1,200 to pay the first-semester bill on time, hence:

1200 + 1191.07 = $2,391.07.

She needs to earn $2,391.07 during the summer.

1/10( x + 130) = -2(3-X)<br><br> I need help
Artist 52 [7]

Answer:

x = 10

Step-by-step explanation:

1/10(x + 130) = -2(3 - x)

x + 130 = -20(3-x)

x + 130 = -60 + 20x

x - 20x = -60 - 130

-19x = -190

x = 10

A square park has an area of 6561 square meters. If you walk around the park what is the distance that you would have walked?
Paraphin [41]
First we have to find length of 1 side of the square. We can use formula for area of the square. A=a*a   ==>  A=a^2 where a is length of the side.
From this formula we can find
a= \sqrt{A}
a=\sqrt{6561} =81 - 1 side
Now we just have to multiply it by 4, because there are 4 sides.
81*4=324 - its the answer
