Answer: d = 29 miles

Step-by-step explanation:

S11°W  = 259° on a unit circle

N75°E = 15° on a unit circle

x separation after two hours

x = 2(8cos15 - 18cos259) = 21.179 miles

y separation after two hours

x = 2(8sin15 - 18sin259) = 19.7398 miles

total distance between them is

d = √(19.7398² + 21.179²) = 28.9518... ≈ 29 miles

A delivery truck is transporting boxes of two sizes large and small. The combined weight of a large box and a small box is 80 po
Liula [17]

Answer:

small=15 large=40

Step-by-step explanation:

x=large box

y=small box

55 = x + y

 

50x + 55y = 2825

 

50x + 55( 55 - x) = 2825

 

50x + 3025 - 55x = 2825

 

0 = 55x - 50 x + 2825 - 3025

 

0 = 5x - 200

 

200 = 5x

 

x=40

 

y = 15

Helpp plzzz<br> Thank you

Given:

32 and 28 are the two numbers.

To find:

(a) The GCF of 32 and 28.

(b) Using the GCF, find the factor of (32-28).

Solution:

(a)

The factor forms of the given numbers are:

32=2\times 2\times 2\times 2\times 2

28=2\times 2\times 7

It is clear that, 2 and 2 are the common factors in both.

GCF(32,28)=2\times 2

GCF(32,28)=4

Hence, the GCF of 32 and 28 is 4.

(b)

Using the GCF we need to find the factor of (32-28).

32-28=4\times 8-4\times 7

Taking out the GCF, we get

32-28=4\times (8-7)

Hence, 32-28=4\times (8-7).

9x + 7y = 10<br> 7x + 7y = 14
Veronika [31]
Multiply the second row by -1 to cancel out the 7x.
9x+7y=10
-7x-7y=-14
2x=-4
x=-2

9(-2)+7y=10
-18+7y=10
7y=28
y=4
