Answer:

620 is the number of boys in the school

Explanation:

1400 is the number of students in the school, since we know how many girls there are in the school then we can subtract the number of girls from how many total students are in the school. So you gotta subtract 780 from 1400 which is 620, the number of boys in the school.

Answer:

(a) Percentage of girls = 55\frac{5}{7}

(b) Percentage of boys = 44\frac{2}{7}

Step-by-step explanation:

To find percentage, we multiply the fraction out of the total by 100%.

Percentage of girls = \frac{780}{1400} × 100%

                                = 55\frac{5}{7}

Percentage of boys = \frac{1400-780}{1400} × 100%

                                 = 44\frac{2}{7}

Find the range of ƒ(x) = –x + 4 for the domain {–3, –2, –1, 1}.
qaws [65]

Answer:

range {3, 5, 6, 7 }

Step-by-step explanation:

to find the range substitute each value of x from the domain into f(x)

f(- 3) = -(- 3) + 4 = 3 + 4 = 7

f(- 2) = - (- 2 + 4 = 2 + 4 = 6

f(- 1) = - (- 1) + 4 = 1 + 4 = 5

f(1) = - 1 + 4 = 3

range y ∈ { 3, 5, 6, 7 }

Solve for k. <br><br><br> 9(3-2x)=2(10-8x)
GrogVix [38]

Answer:

Step-by-step explanation:

9(3−2x)=2(10−8x)

Step 1: Simplify both sides of the equation.

9(3−2x)=2(10−8x)

(9)(3)+(9)(−2x)=(2)(10)+(2)(−8x)(Distribute)

27+−18x=20+−16x

−18x+27=−16x+20

Step 2: Add 16x to both sides.

−18x+27+16x=−16x+20+16x

−2x+27=20

Step 3: Subtract 27 from both sides.

−2x+27−27=20−27

−2x=−7

Step 4: Divide both sides by -2.

−2x −2  =  −7 /−2  

x= 7/ 2

Answer:

x= 7/ 2

Converges or Diverges: Please help me​
bagirrra123 [75]

Use a/ 1-r

Where a = 18 and r = 1.2

18/ 1 - 1.2 = 18/-.2 = -90

Because the answer is below 1. The sum does not exist therefore it diverges.
