Answer:

Initial value: $25; Rate of change: 48; Equation: y= 8x + 25

Step-by-step explanation:

The initial value would be the $25 due to the fact that that's how much money she made during training. After that, her money will go up by $8 for every hour she works for, which is why that's the rate of change.

The equation just restates all that, the rate of change is always represented by the mx in the equation (8 replaces the m), and 25 replaces the b, the start of the line, or on a graph, where the initial dot would be on the y-axis.

Given:

The two ways table.

To find:

The number of girls in year 9.

Solution:

Using the two ways table, we get

Boys in year 10 = Total student in year 10 - Girls in year 10

                        = 256 - 123

                        = 133

Boys in year 9 = Total boys - Boys in year 10 - Boys in year 11

                        = 407 - 133 - 125

                        = 149

Girls in year 9 = Total students in year 9 - Boys in year 9

                       = 303 - 149

                       = 154

Therefore, the number of girls in year 9 is 154 and the correct option is C.

Answer:

1.27

Step-by-step explanation:

To write 127/100 as a decimal you have to divide numerator by the denominator of the fraction.

We divide now 127 by 100 what we write down as 127/100 and we get 1.27

Answer:

1.27

Step-by-step explanation:

To write any fraction as a decimal, you just have to divide the numerator by the denominator. As a variable equation, I have written it below

n / d

Where n = numerator    and d = denominator

now weite ur answer

Step-by-step explanation:

Triangle inequality theorem =The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

9 + 5 > 7

14 > 7 (True) ✔

5 + 7 > 9

12 > 9 (True) ✔

9 + 7 > 5

16 > 5 (True) ✔

So these side measures form a triangle.

Answer:

6 km/hr or 5 km/hr

Step-by-step explanation:

In the lake, she goes 15 km at x km/hr (named)

In the river, she goes 6 km at x-2 km/hr (current=2 km/hr)

So, the time in the lake -  the time in the river = 1 hour (given)

15/x - 6/x-2 = 1 --> x=6;x=5

The speed of the boat as the photographer paddles the lake if the river current is 2 km/h is 6 km/hr and this can be determined by forming the quadratic equation.

Given :

According to the given data, if the river current velocity is 2 km/hr then let the speed in the lake be x km/hr. So, the speed of the photographer in the river is (x - 2) km/hr

Therefore, the speed of the boat as she paddles the lake if the river current is 2 km/h is given by:

[tex]\dfrac{15}{x} - \dfrac{6}{x-2}=1[/tex]

Now, simplify the above expression.

[tex]15(x-2)-6(x)=x(x-2)[/tex]

[tex]15x-30-6x=x^2-2x[/tex]

[tex]x^2-11x+30=0[/tex]

Factorize the above equation.

[tex]x^2-6x-5x+30=0[/tex]

x(x - 6) - 5(x - 6) = 0

(x - 6)(x - 5) = 0

x = 6 or 5

Answer:

Ethan and Isabella are 9 meters apart.

Step-by-step explanation:

1. We can solve this using the Pythagorean Theorem, a²+b²=c².

2. Mrs. Gretta is standing 12 meters in front of Ethan, so a=12.

3. Isabella is sitting to Ethan's right, but we don't know how far away, so b=x.

4. Mrs. Gretta is 15 meters from Isabella, so c=15.

5. Plugging these variables into the equation, we get 12²+x²=15² which equals 144+x²=225.

6. We can move 144 to the other side to get x²=81, then square the 81 to get x=9.

7. Therefore, the answer is 9. Ethan and Isabella are 9 meters apart.
