Could someone please help??? "What is the simple interest that is missing from the table? Use the formula 1 = prt "

Answer:

Janine is 28. Ingrid is 30.

Step-by-step explanation:

Let the ages be x and x + 2 for Janine and her sister, respectively.

x/7 + (x + 2)/3 = 14

Multiply both sides by the LCD, 21, to get rid of denominators.

21 * x/7 + 21 * (x + 2)/2 = 21 * 14

3x + 7(x + 2) = 294

3x + 7x + 14 = 294

10x = 280

x = 28

x + 2 = 30

Answer: Janine is 28. Ingrid is 30.

Answer:

Janine is 28 and Ingrid is 30.

Step-by-step explanation:

Let Janine's age be x years , then Ingrid's age is x+2 years.

From the given information we have the equation:

x/7 + (x + 2)/3 = 14

Multiplying through by the LCM of 3 and 7 (21),  we have:

3x + 7(x + 2) = 294

10x + 14 = 294

10x =  294-14 = 280

x = 28, so:

Janine is 28 and Ingrid is 30.

Answer:

9 + 7n - 3 ;

61 ;

Step-by-step explanation:

Let the number = n

9 + 7*n - 3

Hence, the expression is :

`9 + 7n - 3

If the number,n = 8

The value of the expression becomes :

9 + 7(8) - 3

8 + 56 - 3

= 61

Answer:

nine more than the product of seven and a number, decreased by three

The expression to model the situation is  

✔ 9 + 7n – 3

.

The value of the expression when n = 8 is  

✔ 62

Answer:

19

Step-by-step explanation:

Rearranging the number in ascending order,

12,15,17,19,19,20,24,26

Median = The average of the 4th and 5th number

[tex] = \frac{19 + 19}{2} \\ = 19[/tex]

Answer:

19

Step-by-step explanation:

so first you have to order the values from least to greatest.

12, 15, 17, 19, 19, 20, 24, 26

there are 8 terms (note that 2 of them are 19)

n = 8

median = (n + 1) ÷ 2

            =(8 + 1)/2

            =9/2 = 4.5

it's 19 because the median falls between those two (19) data points.

Answer:

2.9195

Step-by-step explanation:

To find the time we need to equate the function the zero and solve for t:

[tex] { - 16t}^{2} + 45t + 5 = 0[/tex]

Using the general formula we have that:

[tex]t = \frac{ - 45 + \sqrt{ {45}^{2} - 4 ( - 16)(5)} }{2( - 16)} \\ = \frac{ - 45 + \sqrt{2345} }{ - 32} [/tex]

then:

[tex]t = \frac{ - 45 + \sqrt{2345 } }{ - 32} = - 0.107 \\ or \\ t = \frac{ - 45 - \sqrt{2345} }{ - 32} = 2.9195[/tex]

Since the time has to be positive we conclude that the ball is in the air 2.9195 seconds.

Answer: .

Step-by-step explanation:

The fourth graph represents the function  [tex]f(x)=\frac{3}{2} 2^{x}[/tex]

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given function is [tex]y=\frac{3}{2} 2^{x}[/tex]

It is an exponential function and 2>1, therefore it is an increasing in nature.

put x=0 in the given function to find the y-intercept of the graph.

f(0)=3/2.2⁰

f(0)=3/2(1)

f(0)=3/2=1.5

So, the y-intercept is 1.5.

In figure 1 and figure 1 the y-intercept is 1,  in figure 2 the y-intercept is 2 , therefore first three options are incorrect.

In figure 4 the y-intercept is 1.5, therefore the option 4 is correct.

Hence, the fourth graph represents the function  [tex]f(x)=\frac{3}{2} 2^{x}[/tex]

Answer:

(9, 57/7)

Step-by-step explanation:

Given the coordinates A(5 , 5)  and B(19 , 16), divided by the point P in the ratio 5:2, to get the coordinate of P, we will use the formula;

P(X, Y) = {{ax1+bx2/a+b, ay1+by2/a+b}

X = ax1+bx2/a+b

Substitute the given values

X = 5(5)+2(19)/5+2

X = 25+38/7

X = 63/7

X = 9

Similarly;

Y = 5(5)+2(16)/5+2

Y = 25+32/7

Y = 57/7

Hence the coordinate of point P is (9, 57/7)

Answer:

12 fish are girls

Step-by-step explanation:

multiply 4/6 by 6 which would be 24/36. Then substract 24 from 36 and you get 12.

Answer:

12 are girls

Step-by-step explanation:

Reason that since 4/6 of them are boys then that means 2/6 are girls

then convert 2/6 to decimal form which is 0.3333....

then multiply that by 36 which gives us 12

you could also go the roundabout way and convert 4/6 to decimal form and take that value and multiply it by 36 which gives us 24 then subtract 24 from 36 which still gives us 12

Answer:

1. m = 65°

x = 30°

2. x = 40°

Step-by-step explanation:

1. Since the figure is an isosceles triangle, m = 2x - 5

180 - 50 = 130 (Total degree for both m and 2x - 5)

130 ÷ 2 = 65 (m and 2x - 5 angle degrees)

65 - 5 = 60 (2x)

2 x = 60°

x = 60 ÷ 2 = 30°

2. I forgot the parallel rule for question 2, but I think X and 40° is parallel to each other?
