Step-by-step explanation:

Answer:

48

Step-by-step explanation:

Remark

Use a^2 + b^2 = c^2 to solve for the height.

Givens

c = 10

b = 6

h = ?

Solution

b^2 + h^2 = c^2

6^2 + h^2 = 10^2

36 + h^2 = 100            Subtract 36

h^2 = 100 - 36

h^2 = 64                      Take the square root of both sides

sqrt(h^2) = sqrt(64)

h = 8

The height = 8

Area = 1/2 * b * h

Area = 1/2 *12 * 8

Area = 48

Comment

You might wonder where the 12 came from. It wasn't given The base is the whole line across the bottom. 1/2 of it is six. The whole base = 12

Answer:

10mins

Step-by-step explanation:

you can draw a rtd chart for this problem

             rate (m/min)|  time (mins)  | distance (m )

regular: (300/x)  | x  | 300m

fist 1/4 : (300/x) | 75: (300/x)  | 75m

last 3/4:  | (300/x)+15 | 225:(300/x + 15) | 225m

then, make an equation for the times:

x= (75: (300/x)) + (225: ( (300/x)+15) + 2.5 = x

// get the 2.5 mins from the stop for honey, and we know that regular speed is equal to the one with a stop

solve equation to get x=-20/3 , x=10, because speed is positive, x=10 is the most reasonable answer

-2, -3 and -2, 4 have the same x coordinate, so you only need to find the difference between -3 and 4.

Answer:

t = 35.13

Step-by-step explanation:

Simplifying

62.52 = 27.39 + t

Solving

62.52 = 27.39 + t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-1t' to each side of the equation.

62.52 + -1t = 27.39 + t + -1t

Combine like terms: t + -1t = 0

62.52 + -1t = 27.39 + 0

62.52 + -1t = 27.39

Add '-62.52' to each side of the equation.

62.52 + -62.52 + -1t = 27.39 + -62.52

Combine like terms: 62.52 + -62.52 = 0.00

0.00 + -1t = 27.39 + -62.52

-1t = 27.39 + -62.52

Combine like terms: 27.39 + -62.52 = -35.13

-1t = -35.13

Divide each side by '-1'.

t = 35.13

Simplifying

t = 35.13

hope it helps !!!!!!!!!!!    :)

Answer:

4/3

10/3

24/3

...........

Answer:

4/3

10/3

24/3 or 8

Step-by-step explanation:

x = y - 2/3

2 - 2/3 = 2/1 - 2/3 = 6/3 - 2/3 = 4/3

y = x + 2/3

8/3 + 2/3 = 10/3

y = x + 2/3

22/3 + 2/3 = 24/3 = 8

Answer:

[tex]6\frac{7}{10}x + 9[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex]3(\frac{7}{5}x + 4)-2(\frac{3}{2}-\frac{5}{4}x)[/tex]

[tex](3*\frac{7}{5}x) + (3 * 4) + (-2 * \frac{3}{2}) + (-2 * -\frac{5}{4}x)[/tex]

[tex]\frac{21}{5}x + 12 + \frac{-6}{2} + \frac{10}{4}x[/tex]

Step 2:  Combine Like Terms

[tex]12 - 3 + \frac{21}{5}x + \frac{5}{2}x[/tex]

[tex]9 + (\frac{21*2}{5*2}x + \frac{5*5}{2*5})[/tex]

[tex]9+(\frac{42}{10}x + \frac{25}{10}x)[/tex]

[tex]9+\frac{67}{10}x[/tex]

[tex]6\frac{7}{10}x + 9[/tex]

Step-by-step explanation:

Let n and n+4 be the numbers. Then:

n² + 3(n+4)=66

n²+3n-54=0

(n+9)(n-6)=0

n=6 or -9

n+4=10

Assuming positive integers only, the numbers are 6 and 10…..

Answer:

Each monthly payment is of £560.

Step-by-step explanation:

Sue buys a car costing £8000 plus 20% VAT?

She has to pay:

8000 plus 20% of tax. So

[tex]T = 8000 + 0.2*8000 = 9600[/tex]

She pays £4000 deposit and then chooses to pay the balance in ten equal monthly payments.

4000 deposit, and then 9600 - 4000 = 5600 divided in ten equal monthly payments.

5600/10 = 560

Each monthly payment is of £560.

Answer:

Step-by-step explanation:

The person I sent it to couldn't see it either. I'm going to take a chance and say the Chord (AB) and the Tangent line form a 50 degree angle. If this is incorrect, I won't know, from the diagram, what else to try.

If I'm right then <OAB = 40 degrees because 90 - 50 = 40 because <AOC is a right angle (property of radii and tangents).

<ABO also = 40 (the triangle is isosceles by two legs being radii).

That means that BOA = 180 - 40 - 40 = 100
