Lundi elle dépense: 90: 3 = 30

il lui reste 60 $
6 0 : 3 = 20 

elle dépense 20 $ chaque jour

=$20
This is because 1/3 of 90 is 30 because you do 90÷3. So 90-30=60. She has $60 left and spends it equally in 3 days. Simply do 60÷3=20. So she spends $20 on each of the three days.

Write the following quadratic in standard form. Then identify a, b, and c.<br> y² - 7y + 6 = -6
Charra [1.4K]

Answer:

Therefore,

y^{2}-7y+12=0       ....Standard form.

a=1\\b=-7\\c=12    ......Numerical Coefficients.

Step-by-step explanation:

Given:

y^{2}-7y+6=-6

To Find:

a ,b , c

Solution:

Quadratic:

A quadratic equation is an equation of the second degree.

Meaning it contains at least one term that is squared.

The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

Here it is given as

y^{2}-7y+6=-6

Adding 6 on both the side we get

y^{2}-7y+6+6=-6+6

y^{2}-7y+12=0

Which is Quadratic Equation in STANDARD form Where,

a=1\\b=-7\\c=12

Therefore,

y^{2}-7y+12=0       ....Standard form.

a=1\\b=-7\\c=12    ......Numerical Coefficients.

So I have another trigonometry question PLZ HELP ME I'm clueless at this rate I have like a little idea but I'm lost, SO PLZZZ!
Sergio039 [100]

Answer:

1) The windsurfer is approximately 580 ft from each lifeguard stand.

2) The distance between the Earth and Mercury is approximately 61 million miles.

Step-by-step explanation:

The image other two situations described is presented in the attached image to this answer.

1) From the attached image, the windsurfer forms a right angled triangle with each of the lifeguard stand and the midpoint between the two lifeguard stands.

Hence, the angle at the top of the triangle is half of 30°, 15° and the distance from the midpoint of the lifeguard stands to the lifeguard stands is 300/2 = 150 ft.

Let the required distance of the windsurfer from each of the lifeguard stands be x.

Using trigonometric relations,

Sin 15° = (150/x)

x = 150 ÷ sin 15° = 150 ÷ 0.2588

x = 579.6 ft = 580 ft to the nearest whole number

2) From the image, the Sun, Earth and Mercury form a triangle.

Let the possible distance between the Earth and Mercury be y.

Using cosine rule,

y² = 36² + 93² - (2×36×93×cos 22°)

y² = 3,736.5769098208

y = √3,736.5769098208 = 61.13 million miles = 61 million miles to the nearest million miles.

Hope this Helps!!!
