1 answer:

7 0

If you would like to know how many total hours did Jeff work today, you can calculate this using the following steps:

4 2/3 hours in the morning + 3 3/4 hours in the afternoon = 4 2/3 + 3 3/4 = 14/3 + 15/4 = 56/12 + 45/12 = (56 + 45) / 12 = 101/12 = 8 5/12 hours

Jeff worked 8 5/12 hours in total.

a playing field measures 120 yards by 64 yards supose you run dignolly across the field use he pythagorean theroem to determine

Aloiza [94]

You have to use the Pythagoras theorem: c² = a²+b²
You have been given the c side, the diagonal side, and the b side the height side. You need to square both of them, take them away from each other and then get the square root of that answer;

120²-64² = 10302
√10302 = 101.49

The answer is 101.49ft,
Hope this helps! :)

*At first a price was decreased by 12%, then it was discounted again by an additional 5%. What is the percent of the total disco

ratelena [41]

The percent of total discount is 16.4 %

Solution:

Given that,

At first a price was decreased by 12%, then it was discounted again by an additional 5 %

To find: Percent of total discount

Let "x" be the original price

At first a price was decreased by 12%

Therefore,

Discounted price = original price - 12 % of original price

Discounted price = x - 12 % of x

$Discounted\ price = x - \frac{12}{100} \times x\\\\Discounted\ price = x - 0.12x\\\\Discounted\ price = 0.88x$

It was discounted again by an additional 5%

Therefore,

Discounted price = 0.88x - 5 % of 0.88x

$Discounted\ price = 0.88x - \frac{5}{100} \times 0.88x\\\\Discounted\ price = 0.88x - 0.05 \times 0.88x\\\\Discounted\ price = 0.88x - 0.044x\\\\Discounted\ price = 0.836$

Thus the percent of total discount is:

$Percent = 100 \% - 0.836 \times 100 \%\\\\Percent = 100 \% - 83.6 \%\\\\Percent = 16.4 \%$

Thus the percent of total discount is 16.4 %

Write an equation for an ellipse centered at the origin, which has foci at (\pm5,0)(±5,0)(, plus minus, 5, comma, 0, )and vertic

Virty [35]

Answer:

The equation of ellipse is

$\frac{x^2}{41}+\frac{y^2}{16}=1$

Step-by-step explanation:

The equation of an ellipse is

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$

where(h,k) is the center and c is distance from the center to the foci is given by $a^2-b^2=c^2$ . a is the distance from the center to the vertices and b is the distance from the center to the co-vertices.
