Answer:

$153.00

Step-by-step explanation:

A = $1,353.00

(I = A - P = $153.00)

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year.

Solving our equation:

A = 1200(1 + (0.0425 × 3)) = 1353

A = $1,353.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,200.00 at a rate of 4.25% per year for 3 years is $1,353.00.

Answer:

1) when tomato patch is 6.5 feet the area is 191.75 sq.ft

2) when tomato patch is 7 feet the area is 217 sq.ft

3) when area is 338 sq.ft the tomato patch is 9.0778 feet

4) when area is 147.25 sq.ft the tomato patch is 5.543799 feet

Step-by-step explanation:

The given equation is :

3x^2 + 10x

Length of Tomato (in feet) x, 6.5 , x , 7

Patch Area of Vegetable Garden (in square feet) 338, x , 147.25, x

So we can find the missing terms with the help of the equation 3x^2 + 10x

Putting the values of x from the length of the tomato patch

1) 3x^2 + 10x= 3(6.5)²+ 10 (6.5)=126.75+ 65= 191.75 square feet

2) 3x^2 + 10x= 3(7)² +10 (7)= 147+70= 217 square feet

So the area of her vegetable garden for a variety of lengths of the tomato patch= 6.5 feet is 191.75 square feet

and for 7 feet is 217 square feet

Similarly we can find the length of the tomato patch from the area by again using the given equation 3x^2 + 10x

So when area = 338 square feet

The equation becomes

3x^2 + 10x= 338

Rearranging it : 3x^2 + 10x-338 =0

This is a quadratic equation and can be solved with the help of the formula.

Here a= 3, b= 10 and c= -338

x = -b±√b²- 4ac/2a

Putting the values of a,b,c we get

x= -10±√100+ 4056/6

x= -10± 64.467/6

x= 54.467/6 or -74.467/6 we ignore the negative value because the garden cannot have the negative area.

x= 9.0778 feet

Similarly repeating the same process would give

So when area = 147.25 square feet

The equation becomes

3x^2 + 10x= 147.25

Rearranging it : 3x^2 + 10x-147.25 =0

This is a quadratic equation and can be solved with the help of the formula.

Here a= 3, b= 10 and c= - 147.25

x = -b±√b²- 4ac/2a

Putting the values of a,b,c we get

x= -10±√100+ 1767/6

x= -10± 43.208/6

x= 33.208/6 or -53.208/6 we ignore the negative value because the garden cannot have the negative area.

x= 5.543799 feet

Answer:I think it’s 269 because when you do 1,350 divided by 50 it’s 27 then you add 9+2 to get 11/50 then you do 27x11 which gives you 270 and the closest answer to that is 269

The equation y = 65.18x+21.43 fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9874. Ho

pashok25 [27]

Given:

There is an equation given as

$y=65.18x+21.43$

fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9874.

Required:

We need to find that what will be worth at x= 32 days?

Explanation:

The equation fits the scatter plot of the values for stock ABC over past month with r-value of 0.9874 is

$y=65.18x+21.43$

to find ABC will be worth at x=32 just substitute x=32 in the given equation

$y=65.18(32)+21.43=2058.76+21.43=2107.19$

Final answer:

Therefore, $2107.19 ABC will be worth at x=32 days

roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz. which best describes the percent of increase in

laila [671]

The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.

Step-by-step explanation:

The given is,

Roberto score on math quiz at last week is 74

This week he made an 85 on the quiz

Step:1

Formula to calculate the percentage of increase the score,

$Percentage of increase = \frac{Final score-Starting score}{Starting score}$ × 100...........(1)

From the given,

Final score = 85

Starting score = 74

Equation (1) becomes,

$Percentage of increase =( \frac{85-74}{74})$ × 100

= $(\frac{11}{74})$ × 100

= 0.1486486 × 100

= 14.86486 %

≅ 14.87 %

Percentage of increase = 14.87 %

Result:

The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
