The phone company A Fee and Fee has a monthly cellular plan where a customer pays a flat
11111nata11111 [884]

Answer:

<u>The equation is:</u>

  • y = mx + b

<u>We have two points:</u>

  • (310, 68) and (620, 99)

A)

<u>Find the slope using these two points:</u>

  • m = (99 - 68)/(620 - 310) = 31/310 = 0.1

<u>Use one of the points to find the y-intercept b:</u>

  • 68 = 0.1*310 + b
  • 68 = 31 + b
  • b = 68 - 31
  • b = 37

<u>The equation is:</u>

  • y = 0.1x + 37

B)

<u>Find the value of y when x = 980:</u>

  • y = 0.1*980 + 37
  • y = 98 + 37
  • y = 135

The total cost is $135

Please someone help answer correctly !!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!
kogti [31]

Answer:

z = 44

Step-by-step explanation:

180 - (44+52) = 180 - 96 = 84º

180 - 84 = 96º

180 - (96 + 40) = z

     180 - 136 = z

     z = 44

Kite EFGH is inscribed in a rectangle such that F and H are midpoints and EG is parallel to the side of the rectangle.
aivan3 [116]

Answer:

"The area of EFGH is always One-half of the area of the rectangle."

Step-by-step explanation:

<em>Graph is attached.</em>

<em />

The kite consists of 2 triangle, EFG and EHG.

The area of EFG:

\frac{1}{2}*EG*h

where h is the height from F to EG

The area of EHG:

\frac{1}{2}*EG*h_1

where h_1 is the height from H to EG

We also know that h + h _1 is the width of the rectangle and EG is the length of the rectangle

Thus,

Area of Kite = \frac{1}{2}*EG*h + \frac{1}{2}*EG*h_1 = RectangleLength*RectangleWidth

Also, Area of rectangle is rectangle length * rectangle width.

Thus, area of kite is always half of that of rectangle, the third choice is right.

Answer:

Cost = 112.266 cent/km

Step-by-step explanation:

Given

Unit\ cost = R17.82/litre

Rate = 6.3litre/100km

Required

The fuel cost in cent\ per\ km

This is calculated using:

Cost = Unit\ cost * Rate

Cost = R17.82/litre * 6.3litre/100km

Cost = R17.82 * 6.3/100km

Cost = R1.12266/km

Multiply by 100 to get the cost in cents

Cost = 1.12266 * 100 cent/km

Cost = 112.266 cent/km
