QUESTION POSTED AT 14/12/2019 - 05:40 PM

Given Situation: What is the percent increase from the 20 students to the 30 students.
Solution:
=> Let’s find how many percent did it increase.
Let’s have 20 as the first total number of the students in the first counts.
=> Then it became 30 students, let’s find out how many students added.
=> 30 – 20 = 10, there are 10 students added
10 is 50% of 20, thus, 50% added to the number of students. And that makes it 30 as the total count.

The answer is B.

The total number of students is 24 and the total number of boys is 6, therefore

Number of girls = 24 – 6 = 18

Therefore the ratio of the boys to girls is

Number of boys/ number of girls = 6/18 ~ 1/3

The ratio suggests that there is 1 boy for every 3 girls

**Answer:**

**10 in**

**Step-by-step explanation:**

We are given that

Diameter of cactus=d=12 in

Radius of cactus=

Distance of lizard from point of tangency=8 in

We have to find the direct distance between lizard and cactus.

In triangle OAB,

OA=6 in

AB=8 in

**Pythagorous theorem: **

Using pythagorous theorem

**Hence, the direct distance of lizard from cactus=10 in**

QUESTION POSTED AT 18/01/2020 - 12:54 PM

**Answer:**

Option D. (120, 80, 40)

**Step-by-step explanation:**

Let the cost of 3 baseball cards bought by Andrew are $x, $y and $z.

Now we will form the equations to find the unknown values of x, y, and z.

**Statement 1** - Andrew bought 3 baseball cards for $240

Equation will be **(x + y + z) = 240 --------(1)**

**Statement 2** - Jack offered a deal to buy the first card for the double of its original value along with the second card for $320.

Equation will be **2x + y = 320 --------(2)**

**Statement 3** - Jack offered another deal to buy first card for the double of its original value along with third card for $280

Equation formed** 2x + z = 280 ------(3)**

Now we can solve these equations to get the values of x, y and z.

**From equation 2**

y = 320 - 2x

**From equation 3**

z = 280 - 2x

Now we can replace the values of y and z in equation number 1.

Equation 1 becomes after substitution of y and z values

x + (320 - 2x) + (280 - 2x) = 240

Now we will group the similar terms

(x - 2x - 2x) + (320 + 280) = 240

-3x + 600 = 240

-3x = 240 - 600

-3x = - 360

x =

x = 120

Now we put x = 120 in the value of y

y = 320 - 2x

y = 320 - 2×120

= 320 - 240

= 80

Similarly we put the value x = 120 in value of z

z = 280 - 2x

= 280 - 2×120

= 280 - 240

= 40

So the original values of 3 baseball cards are (120, 80, 40)

**Option D**. will be the answer.

A parentage value is a value that has been compared to 100.

Percentage = (change in the value)/(the original value) × 100%

= (35-25)/25 × 100%

= 10/25 × 100%

35 Percent of 70 is 24.5

We assume, that the number 70 is 100% - because it's the output value of the task. We assume, that x is the value we are looking for. If 70 is 100%, so we can write it down as 70=100%. We know, that x is 35% of the output value, so we can write it down as x=35%. Now we have two simple equations: 1.)70=100% 2.)x=35%where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 70/x=100%/35% Now we just have to solve the simple equation, and we will get the solution we are looking for.

**Answer:**

105%.

**Step-by-step explanation:**

We are asked to convert 1.05 to a percent.

To convert a decimal to percent, we simply multiply the decimal number by 100 and add a percentage sign.

Let us multiply 1.05 by 100.

**Therefore, 1.05 as a percent would be 105%.**

The *correct answer* is:

d.) 1040-A

**Explanation**:

A 1040-EZ is used if you are single or married filing jointly, make less than $100,000, and have no adjustments to your income. Sandy and Alex wish to deduct student loan interest, so they cannot use this form.

The next one is the 1040-A. This one can be used to deduct student loan interest, so this would be the one they should use. It is the simplest form that will allow them to claim what they wish to claim.

QUESTION POSTED AT 18/01/2020 - 12:37 PM

| x - (-30) |

which can be simplifed into

| x + 30 |

We use absolute value because distance cannot be negative.

Laurie must stay within 10 feet. Therefore, the distance x is from -30 feet has to be equal to 10 to find the maximum and minimum depths that Laurie can stay between:

| x + 30 | = 10

When we solve this absolute value equation, we work with two cases.

Case 1: When x + 30 is positive, then |x+30| = x+30 (no change) and we have the equation

x + 30 = 10

Case 2: When x + 30 is negative, then |x+30| = -(x+30) so as to force the distance into a positive number. Then this gives us the equation

-(x+30) = 10

which we can multiply both sides by -1 to get

x + 30 = -10

**Answer:**

Interest paid = $2,095.30

**Step-by-step explanation:**

Gertrude takes out a $5,500 subsidized Stafford loan.

The loan has an interest rate of 6.8%, compounded monthly.

Present Value = $5,500.

Time period = 10 years. So N = 10 x 12 = 120 months.

Interest rate, R = 6.8/1200 = 0.005666667

Then PV = Pmt * [1 - (1+R)^(-N)]/(R)

5500 = Pmt * [1 - (1+0.005666667)^(-120)]/(0.005666667)

Pmt = $63.29418157

She made total repayment = 63.29418157 x 120 = $7,595.30

Interest paid = Total repayment - Loan Principal = $7,595.30 - $5,500 = $2,095.30

**Interest paid = $2,095.30**
