The ratio of boys to girls is 4 to 3.The team has 35 members.How many are girls?

1 answer:

7 0

I like to do it by adding 4 and 3 to get 7. then divide 35 by 7. that would be 5. take 5*4 to get 20 boys and 5*3 to get 15 girls.

Answer:

83.35 feet above ground.

Step-by-step explanation:

Please find the attachment.

We have been given that Hudson (3 feet tall) is on the beach flying a kite. His angle of elevation looking up to the kite is 40 degrees. The kite string is 125 ft long.

We can see that the string of kite forms a right triangle with an angle of elevation (40 degrees) as shown in the attachment.

To solve for h, we will use sine as sine related opposite side of a right triangle with hypotenuse.

$\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}$

$\text{sin}(40^{\circ})=\frac{h}{125}$

$h=125\cdot \text{sin}(40^{\circ})$

$h=125\cdot 0.642787609687$

$h=80.348451210875\approx 80.35$

To find the height of kite off the ground, we will add height of Hudson to 80.35 feet as well as he is flying the kite.

$80.35+3=83.35$

Therefore, the kite is approximately 83.35 feet above ground.

the vertex of this parabola is at 4,-3 when the x value is 5 the y value is -6 what's the coefficient of the squared expression

schepotkina [342]

Answer:

d) -3

Step-by-step explanation:

The equation of a parabola in vertex form is given as:

y = a(x - h)² + k. Where (h, k) is the vertex of the parabola.

Given that the vertex of the parabola is at (4,-3) i.e h = 4 and k = -3.

The equation of the parabola is given as:

y = a(x - 4)² + (-3)

y = a(x² - 8x + 16) - 3

y = ax² - 8ax + 16a - 3

Given that when x = 5, y = -6. i.e:

-6 = a(5)² - 8a(5) + 16a - 3

- 6 = 25a - 40a + 16a - 3

-6 + 3 = a

a = -3
