Answer:

The answer is sometimes. The base of an isosceles triangle can be equivalent to, longer than, or shorter than the two equivalent legs. As long as two of the legs are equivalent, the triangle is still isosceles and the base length in comparison to the other sides is irrelevant(it could be shorter, longer, equiv.) so the answer is sometimes. Good luck with the rest and message me on Brainly if you need more help. :)

Alondra received a 14% hourly raise, but the number of hours worked decreased by 7.5%. If her wage was $10.50 an hour and she wo

Elodia [21]

Answer:

She will earn $442.89 in one week after the changes.

And this is more than her previous weekly earnings.

Step-by-step explanation:

Given:

Alondra received a 14% hourly raise, but the number of hours worked decreased by 7.5%. If her wage was $10.50 an hour and she worked 40 hours per week before the changes.

Now, to find money she will earn in one week after the changes.

Her wage was = $10.50.

She worked per week = 40 hours.

So, her salary before changes:

$10.50\times 40\\\\=\$420.$

Thus, the salary per week before changes is $420.

Now, to get her salary after 14% hourly raise:

$10.50+14\%\ of\ 10.50\\\\=10.50+\frac{14}{100} \times 10.50\\\\=10.50+1.47\\\\=11.97$

Salary after hourly raise = $11.97 per hour.

Then, to get the number of hours worked decreased by 7.5%:

$40-7.5\%\ of\ 40\\\\=40-\frac{7.5}{100} \times 40\\\\=40-3\\\\=37.$

Number of hours per week after hours of worked decreased = 37 hours.

Now, to get the salary after changes:

Salary after hourly raise × number of hours per week after hours of worked decreased

$=11.97\times 37$

$=\$442.89.$

Salary after changes in one week = $442.89.

As, the previous salary was $420 in one week. 

And after changes this salary is $442.89 in one week which is more than previous. 

Therefore, she will earn $442.89 in one week after the changes.

And this is more than her previous weekly earnings.

The equation of the circle below is x2 + y2 = 5. TRUE OR FALSE?

I am Lyosha [343]

FALSE

The standard form of the equation of a circle is

$(x - a) {}^{2} + (y - b) {}^{2} = r {}^{2}$

With (a, b) representing the centre and r representing the radius.

The radius of the circle in the attachment is 5, and therefore the circle has the following equation.

${x}^{2} + y {}^{2} = 25$

~ Hope this helps you!

What is the equation of the quadratic graph with a focus of (3, 1) and a directrix of y = 5?

mamaluj [8]

Answer:

y = -⅛(x - 3)² + 3

Step-by-step explanation:

(x - h)² = 4p(y - k)

h = 3

k + p = 1

k - p = 5

2k = 6

k = 3

p = -2

(x - 3)² = 4(-2)(y - 3)

(x - 3)² = -8(y - 3)

y = -⅛(x - 3)² + 3
