Using simple interest, the rate of interest on the amount that Samantha borrowed to buy the law equipment is 11.75%.

A simple interest system does not accumulate (compound) interest on both the principal and interest, unlike compound interest.

The simple interest uses the following formula, Interest = Principal x Rate x Period.

This simple interest formula can be reversed to find either the principal, rate, or period, as the case may be.

The loan amount = $800

Period of loan  = 9 months

Total interest paid = $70.50

Rate of interest = (Interest × 100)/(Principal × Time)

= 11.75% ($70.50 x 100)/($800 x 9/12)

Check:

Interest = $70.50 ($800 x 11.75% x 9/12)

Thus, Samantha's interest rate on the loan is 11.75%.

Answer: 577

Step-by-step explanation:

Answer:

577.0      

Rounded to the nearest 0.1 or

the Tenths Place.

Step-by-step explanation:

576.984

You rounded to the nearest tenths place. The 9 in the tenths place rounds up to 10 because the digit to the right in the hundredths place is 8.

Because the tenths place was rounded up from 9 to 10, the tenths place becomes 0 and the ones place is increased by 1. When a 9 is rounded up to 10, that place value becomes 0 and we add 1 to the previous place value.

577.0

When the digit to the right is 5 or greater we round away from 0.

576.984 was rounded up and away from zero to 577.0

Answer:

0.72

Step-by-step explanation:

The answer is that because all you have to do is just 2.16 divided by 3. Equalling to 0.72. Now we just have to do 0.72 + 0.72 + 0.72 and that would equal $2.16.

Answer:

(0,8)

Step-by-step explanation:

What is needed in order to be a function?

A value of x cannot have more than one value of y. In this question, we have that for x = 0, there are 2 values of y: -2 and 8. So one of those can be removed.

Among the options, we have: (0,8), which is the correct answer

The equation in slope-intercept form that represents the situation is y = 5x + 25.

In 3 weeks Ellie she saved $40 and $60 in 7 weeks.

Let x and y represent the number of weeks and the total amount saved respectively.

The equation of a line in slope intercept form is given as:

y = mx + b where m is the slope and b is the y-intercept.

Now when x = 3, y = $40.

Therefore,

y = mx + b

40 = 3m + b                                                                                 --------------(1)

When x = 7, y = $60

y = mx + b

60 = 7m + b                                                                                 -------------(2)

Subtracting (1) from (2),

7m + b - 3m - b = 60 - 40

4m = 20

m = 5

So,

3m + b = 40

3(5) + b = 40

15 + b = 40

b = 25

Hence, the equation of the line in slope intercept form is y = 5x + 25.

To be able to compare the weight of the boxes, we need to have their weight in decimal form:

Box A --> 212.04 kilograms

Box B --> 212 1/4 kilograms

Convert 212 1/4 to decimal:

Box B --> 212.25

We can see that the weight of box B is more than the weight of box A, so we discard options A and C.

To find how much more is the weight of box B, we subtract the quantities:

Answer:

5z² + 35z - 90 = 0

5(z² + 7z - 18) = 0

z² + 7z - 18 = 0

(z - 2)(z + 9) = 0

r=−9, s=2

STEPS USING THE DIRECT FACTORING METHOD

5z²+35z−90

This quadratic equation can be resolved using a revolutionary direct factoring technique that does not rely on guesswork. The equation must have the form x2+Bx+C=0 to be solved using the direct factoring approach. To do this, multiply both sides of the equation by 5.

x²+7x−18=0

Let r and s be the factors for the quadratic equation such that x²+Bx+C=(x−r)(x−s) where the sum of factors (r+s)=−B and the product of factors rs=C

r+s=−7

rs=−18

When the average of the two integers is 1/2*-7=-7 /2, the sum of the two numbers r and s are exactly 7. You can also observe that the parabola symbolized by the quadratic equation y=x2+Bx+C has its axis of symmetry in the middle of r and s. An unknown quantity u separates the values of r and s from the center at an equal distance. Describe r and s about the variable u.

r=−7​/2−u

s=−7​/2+u

Put these in the product equation rs=-18 to solve for the unknown quantity u.

(−27​−u)(−27​+u)=−18

Simplify by expanding (a−b)(a+b)=a2–b2

49​/4−u²=−18

Simplify the expression by subtracting 49/4 on both sides

−u2=−18−49​/4=−121​/4

To find the value of the unknowable variable u, simplify the expression by multiplying by 1 on both sides and taking the square root.

u2=121/4

u=±√121/4=±11/2

The factors r and s are the solutions to the quadratic equation. Substitute the value of u to compute the r and s.

r=−7/2−11​/2=−9

s=−7​/2+11​/2=2

Therefore, r=−9, s=2

The term in the AP whose value is 201 / 2 is 71.3.

The first term of an arithmetic progression is 5 and the common difference is - 3/2.

The formula of the arithmetic progression can be described as follows:

nth term = a + (n - 1)d

where

Therefore, using the arithmetic progression formula,

a = 5

d = 3 / 2

nth term = 201 / 2

let's find the term(n)

Therefore,

- 201 / 2 = 5 + (n - 1) - 3 / 2

- 201 / 2 = 5  - 3 / 2 n  + 3 / 2

- 201 / 2  - 3 / 2 - 5 =  - 3 / 2 n

According to this theorem, if we divide a polynomial P(x) by a factor ( x – a); that isn't essentially an element of the polynomial; you will find a smaller polynomial along with a remainder.

All we need to do is to substitute the value of (a) in the numerator to get the remainder. a is represented in the denominator.

It should be noted that congruence simply refers to a scenario where there are the same triangles.

The SSS Similarity Theorem states that two triangles are similar if all three pairs of matching sides are proportionate.

Compare the shortest sides first, followed by the longest sides, when applying the SSS Similarity Theorem. Two triangles are similar if their corresponding side lengths are proportionate to one another.
