The length of the major axis of the ellipse below is 10 What is the sum of the lengths of the red and blue line segments? A. 10
likoan [24]

Answer:

A. 10

Step-by-step explanation:

As we know that

The length of the major axis of the ellipse is 10

i.e

2 a = 10

Also, the ellipse is the curve that consists of 2 focal points  in order that the total of the distance to the 2 focal points would remain constant for each and every point displayed in the curve

Now we assume that P is the curve point

So,

PF1 + PF2

i.e

2 a (blue line) + (red line)

2 a = 10

Therefore the sum of the length is 10

alukav5142 [94]

Answer:

$110, $44

Step-by-step explanation:

Let x = the total cost to Stefan

Jim buys for:

bicycle: $138

helmet: $16

total: $138 + $16 = $154

Jim's price of $154 is 140% of Stefan's cost, x.

154 = 140% × x

1.4x = 154

x = 110

Stefan spent $110.

Stefan's profit:

$154 - $110 = $44

Answer: $110, $44

Nimfa-mama [501]
If a customer ordered 5 items and the order had a total of 17 wheels, we are to determine the number of wagons that was ordered. A wagon has four wheels, therefore, 17 divided by 4 wheels is equal to 4 r. 1. So, 4 wagons were ordered and one extra wheel to complete the 17 wheels and 5 orders.
