Answer: [tex]d = 103.23 miles[/tex] apart.

Step-by-step explanation:

given data:

ship a = 20miles. = 60miles

ship b = 28miles. = 84miles

time interval = 3hrs.

θ = 90

[tex]d = \sqrt{a^{2}+b^{2}-2ab (cos90) }[/tex]

[tex]d = \sqrt{60^{2}+84^{2}-2(60)(84) *(cos90) }[/tex]

[tex]d = \sqrt{3600+7056-10080*(cos90) }[/tex]

[tex]d = \sqrt{10656-10080*(cos90) }[/tex]

[tex]d = \sqrt{10656-0[/tex]

[tex]d = \sqrt{10656[/tex]

[tex]d = 103.23 miles[/tex]

Answer:

x=2

Step-by-step explanation:

9x+9=25+x

subtract 9 on both sides

9x=16+x

subtract x on both sides

x=2

The solution of equation 9(x + 1) = 25 + x is x =2, which is option A.

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

Given information:

The equation is 9(x + 1) = 25 + x.

To solve for x, we need to isolate x on one side of the equation.

9(x + 1) = 25 + x

First, we can distribute the 9:

9x + 9 = 25 + x

Next, we can simplify by subtracting x and 9 from both sides:

8x = 16

Finally, we can solve for x by dividing both sides by 8:

x = 2

Therefore, the solution is x = 2.

Answer:

mA=56 degrees

Step-by-step explanation:

Complementary angles adds up to 90 degrees. This imply that

[tex](7x+28)+(8x+2)=90[/tex]

From this equation, we can find x:

[tex]15x+30=90\\15x=90-30\\15x=60\\x=\frac{60}{15}\\x= 4[/tex]

Now, we can substitute the value for x into the angle mA:

Step-by-step explanation:

Given that,

No. of chocolate chip cookies = 86

No. of sugar cookies = 42

We need to find the number of identical packages that I can make.

It means we need to find the HCF of these 2 number.

Prime factorization of 86 and 42 as follows :

86 = 2 x 43

42 = 2 x 3 x 7

HCF = 2

Hence, I can make 2 identical packages.

Answer:

Assuming there can only be 2 cookies per identical package, She can make 42 identical packages which contains 2 chocolate chip cookies and 1 sugar cookie.

86 / 2 = 43 chocolate chips cookies

42 / 1 = 42 sugar cookies

With the sugar cookies not having the capability to match the requirements we will assume for this answer that an "Identical Package" is composed of 2 chocolate chip cookies, and a single sugar cookie.

Answer:

Step-by-step explanation:

Answer:

l = 23 cm and w = 5.7 cm

Step-by-step explanation:

Perimeter = twice the length plus twice the width

let w = width

let l = length

l = 5.9 + 3w

57.4 = 2(5.9 + 3w) + 2w

57.4 = 11.8 + 6w + 2w

57.4 = 11.8 + 8w

45.6 = 8w

w = 5.7

Substitute 5.7 for 'w' to get 'l':

l = 5.9 + 3(5.7)

l = 23

Answer:

x= -4 & y=-12

Step-by-step explanation:

multiply y=3x by 2

giving you 2y=6x

subtracting 2y=x+20 from 2y =6x

=> 5x=-20

dividing through by 5

=> x=-4

put x=-4 into y=3x

=> y=3(-4)

y=-12

Answer:

a = 6, b = 8

Step-by-step explanation:

given (2,1)

2a - 1b = 4

-1a + 2b = 10

this gives us:

a + b = 14

solve for a

a = 14 - b

plug into first equations

2(14-b) - b = 4

28 - 2b - b = 4

28 - 3b = 4

24 = 3b

b = 8

now plug b back into your equation for a, and you get:

a = 14 - 8

a = 6

Answers:

1. No solutions

2. Infinitely many solutions

Step-by-step explanation:

[tex]3x+7+10x=7+13x+10[/tex]

Add common terms from both sides of the equation (10x and 3x) & (7 and 10)

[tex]13x+7=17+13x[/tex]

Subtract common terms from both sides (13x and 13x)

[tex]7\neq 17[/tex]

7 does not equal 17; thus, there are no solutions

[tex]-6x-6+8x=-5+2x-1[/tex]

Add common terms from both sides of the equation (-6x and 8x) & (-5 and -1)

[tex]2x-6=-6+2x[/tex]

Reorder the right side of the equation

[tex]2x-6=2x-6[/tex]

Since this is a true statement, there are infinitely many solutions
