Slope is 4/12=1/3

y-10=1/3(x-9)
y-10=1/3x + -3
y = 1/3x + 7

Answer:

61.57 ft

Step-by-step explanation:

Look at the picture. You need to find the base value.

so we can sue the cosine formula here.

cos x° = adjacent / hypotaneous

cos 52 ° = adj / 100

adjacent = 100 cos 52°

=61.57 ft

Belle made a scale drawing of a mural where 2 inches of the drawing represents 3 feet on the actual mural (scale 2 in. = 3 ft.).

Answer:

<h3>Very sorry if this is wrong but, I think the answer would be 48 inches. </h3>

Step-by-step explanation:

If every 3ft. = 2in. then I believe you would first divide the length and width by 3. So 6 divided by 3 is 2 and 18 divided by 3 is 6. Then you would multiply 2 and 6 by 2 since every 3ft = 2in.

Does anyone know this?

weeeeeb [17]

Answer:

BC = 10.24

Step-by-step explanation:

You can use the Pythagoras theorem for this question

$a^{2}$ + $b^{2}$ = $c^{2}$

a = 8cm

b = ???

c = 13cm

We will solve for B (length BC)

$a^{2}$ + $b^{2}$ = $c^{2}$

$8^{2}$ + $b^{2}$ = $13^{2}$

Rearrange for b

$b^{2}$ = $13^{2}$ - $8^{2}$

$b^{2}$ = 105

b = $\sqrt{105}$

b = 10.24

<h2>Answer:</h2>

<u>The length is</u><u> 250 meters</u>

<h2>Step-by-step explanation:</h2>

If we look at the left corner of the diagram we see a scale. According to the scale factor of the map

1 cm :1000 cm

The length of the lap on the map is 25 cm

So (25 × 1000) = 25000 cm

Since

1 meter = 100 centimeter

So the actual length of the lap = 25000 ÷ 100 = 250 meters
