Answer:

h = 20.3 cm

Step-by-step explanation:

Apply trigonometric ratio formula to find h.

Reference angle = 40°

Opposite side length = 17 cm

Adjacent side = h

Thus:

Tan (40) = 17/h

h × tan (40) = 17/h × h (multiplication property of equality)

h × tan(40) = 17

(h×tan(40)/tan(40) = 17/tan(40) (division property of equality)

h = 20.3 cm (1 decimal place)

Answer:

c: 3/4

Step-by-step explanation:

When 2 slopes are parallel, they have the same slope. So anything parallel to m=3/4 is 3/4.

In the picture -4/3 is selected. That is perpendicular. To find something’s perpendicular slope u have to flip the fraction and change the sign.

Answer:

£30

Step-by-step explanation:

Let Brian initially had money in his wallet = £x

and Colin had the money = £y

Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1

Therefore,  

⇒ x = 5y -------(1)

Brian spent £27 that day, so money left with him = £(x - 27)

After spending the money Brian had £3 less than Colin.

(x - 27) = (y - 3)

x = y + 27 - 3

x = y + 24 -------(2)

Now we equate the equations (1) and (2) for the value of x,

5y = y + 24

5y - y = 24

4y = 24

y = £6

From equation (2),

x = 6 + 24

x = £30

Therefore, Brian initially had £30.

Answer:

y= b+ 3a

Step-by-step explanation:

Given data

We are required to rent a bike and a helmet

le the flat fee for bike rental be a

and the flat fee helmet be b

let the number of hours be h

and let the total cost be y

So

y= b+ah

for h = 3

tThen the expression for the total is given as

[tex]y= b+ 3a[/tex]

Step-by-step explanation:

-1 + -5 is -6.

Answer:

The rate of change is 6.

Step-by-step explanation:

Using the point slope form we know that y-y1/x-x1

so 12-6/2-1

this gives 6/1 which is 6.

Answer:

5/18 m

Step-by-step explanation:

You are going to multiply length x width x Height

5/6 x 1/2 x 2/3

Answer:

Step-by-step explanation:

2x - y = 3

x = -2y - 1

2x - y = 3

2(-2y - 1) - y = 3

-4y - 2 - y = 3         {add 2 to both sides}

- 5y = 5             {divide both sides by (-5)}

 y = -1

x = -2y - 1 = -2(-1) - 1 = 2 - 1 = 1

Answer:

that would be 4x+4y

Answer:

[tex]\displaystyle y = -\frac{1}{5} x +6[/tex]

Step-by-step explanation:

Equation of a LIne

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.

This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.

Two parallel lines have equal values for the slopes. The equation of the line

x + 5y = 10

Can be rearranged in such a way we can find its slope. Let's solve it for y:

5y = -x + 10

[tex]y = -\frac{1}{5}+2[/tex]

The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:

[tex]\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )[/tex]

Adding 7:

[tex]\displaystyle y = -\frac{1}{5} ( x + 5 )+7[/tex]

Operating:

[tex]\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7[/tex]

[tex]\displaystyle y = -\frac{1}{5} x -1+7[/tex]

[tex]\boxed{\displaystyle y = -\frac{1}{5} x +6}[/tex]

Answer:

7=-1/5x+6 is the answer

Answer:

x is less than or equal to 16

Step-by-step explanation:

- 2 x x + 4 < 20

Isolate the variable

divide 2 from 2 = 0

x + 4 < 20

x is less than or equal to 16

yes? im pretty sure yeah

Step-by-step explanation:

Answer:

500 miles

Explanation: 100-44 is 56, so 280 is equal to 56% of the trip. 280/56 is equal to 5. Therefore 5 is 1%, so if we multiply the 5 x 100 there we go, that's 100% of the trip. Not how your teacher told you to do it, but its the right answer.

Answer:

x = -1

Step-by-step explanation:

Given

2x + 2 = 4x + 4 ( subtract 4x from both sides )

- 2x + 2 = 4 ( subtract 2 from both sides )

- 2x = 2 ( divide both sides by - 2 )

x = - 1

Answer:

[tex]\frac{12a-14b}{21}[/tex]

Step-by-step explanation:

Express the 2 fractions with a common denominator of 21

multiply numerator/denominator of first fraction by 3

multiply numerator/denominator of second fraction by 7

[tex]\frac{4a(3)}{7(3)}[/tex] - [tex]\frac{2b(7)}{3(7)}[/tex]

= [tex]\frac{12a}{21}[/tex] - [tex]\frac{14b}{21}[/tex]

= [tex]\frac{12a-14b}{21}[/tex]

Answer:

x = 6

Step-by-step explanation:

3x + 5 = 5x - 7

Combine like terms:

3x - 5x + 5 = -7

-2x + 5 = -7

Subtract 5 on both sides

-2x + 5 - 5 = -7 - 5

-2x = -12

x = 6
