Its would be 26$ because 1250 divided by 25$ is 50 and 1300 divided by 50 is 26$

Answer:

$26.

Step-by-step explanation:

We have been given that John's cell phone gives him 1250 minutes for $25. We are asked to find John's bill for 1300 minutes.

First of all, we will find charges per minute by dividing $25 by 1250 as:

\text{Charge per minute}=\frac{\$25}{1250}

\text{Charge per minute}=\$0.02

Now, we will multiply 1300 by $0.02 to find John's bill.

\text{John's bill}=\$0.02\times 1300

\text{John's bill}=\$26

Therefore, John's company will charge him $26 for 1300 minutes.

<span>1. Make y the subject 
a) 4y=12x+18
y = 3x + 4.5

b) 2x=7-3y
3y = -2x + 7
y = -2/3x + 7/3

2.
a) what is the equation of the line which passes through both (-2,-4) and (6,16)

slope = (16 + 4)/(6 +2) = 20/8 = 2.5
y = mx + b
-4 =2.5(-2) +b
-4 = -5 +b
b = 1

equation
y = 2.5x + 1


b) what is the equation of the line perpendicular to y= 1/2X + 7 passing through point (3,9)

</span>y= 1/2X + 7
slope = 1/2

slope of line perpendicular = -2

passing through point (3,9)

y = mx + b
9 = -2 (3) + b
b = 15

equation

y = -2x + 15

Find the value of 3 4(16 - 9). 31 49 58
maw [93]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

3+4(16-9)

We first solve the brackets:

(16-9) = 7

Now, we multiply it with 4

7\times 4=28

Now, we add 3 to it:

28+3=31

Hence, the value of expression would be 31.

Therefore, First option is correct.

Answer:

23\sqrt{3}\ un^2

Step-by-step explanation:

Connect points I and K, K and M, M and I.

1. Find the area of triangles IJK, KLM and MNI:

A_{\triangle IJK}=\dfrac{1}{2}\cdot IJ\cdot JK\cdot \sin 120^{\circ}=\dfrac{1}{2}\cdot 2\cdot 3\cdot \dfrac{\sqrt{3}}{2}=\dfrac{3\sqrt{3}}{2}\ un^2\\ \\ \\A_{\triangle KLM}=\dfrac{1}{2}\cdot KL\cdot LM\cdot \sin 120^{\circ}=\dfrac{1}{2}\cdot 8\cdot 2\cdot \dfrac{\sqrt{3}}{2}=4\sqrt{3}\ un^2\\ \\ \\A_{\triangle MNI}=\dfrac{1}{2}\cdot MN\cdot NI\cdot \sin 120^{\circ}=\dfrac{1}{2}\cdot 3\cdot 8\cdot \dfrac{\sqrt{3}}{2}=6\sqrt{3}\ un^2\\ \\ \\

2. Note that

A_{\triangle IJK}=A_{\triangle IAK}=\dfrac{3\sqrt{3}}{2}\ un^2 \\ \\ \\A_{\triangle KLM}=A_{\triangle KAM}=4\sqrt{3}\ un^2 \\ \\ \\A_{\triangle MNI}=A_{\triangle MAI}=6\sqrt{3}\ un^2

3. The area of hexagon IJKLMN is the sum of the area of all triangles:

A_{IJKLMN}=2\cdot \left(\dfrac{3\sqrt{3}}{2}+4\sqrt{3}+6\sqrt{3}\right)=23\sqrt{3}\ un^2

Another way to solve is to find the area of triangle KIM be Heorn's fomula, where all sides KI, KM and IM can be calculated using cosine theorem.

Solve for x, show your work:<br> 3/5 =x/30
Tpy6a [65]

Answer:

\frac{3}{5}  = \frac{18}{30}

Step-by-step explanation:

To solve this proportion, we will divide the two given denominators.

Now, we have: 30 ÷ 5 = 6

Next, we will multiply the given numerator by the quotient: 3 × 6 = 18

So, our final proportion will have to be:

\frac{3}{5}  = \frac{18}{30}
