Answer:

B. 1,486 metres

Step-by-step explanation:

Find the area of the triangle.

60 x 60 = 3600

3600 ÷ 2 = 1800

Area of triangle = 1800 metres

Area of unshaded circle is approximately 314 metres square using pi

1800 - 314 = 1486

1486 metres square is the approximate area of the shaded region.

Write the equation of the line that is perpendicular to the line 3x + y = 7 and passes through the point (6, -1).
ira [324]
Line:
3x+y=7
y=-3x+7

Slope of Perpendicular Line: 1/3x

For the perpendicular line to contain point (6,-1) the y-intercept would be (0,1), thus the equation of the line would be y=1/3x+1

y=1/3x+1

Emma bought new sneakers from Foot Locker. The price is $90 and the sales tax is 8%. What is the sales tax in dollars?
SCORPION-xisa [38]

Answer:

$7.20

Step-by-step explanation:

8% as a decimal would be 0.08.

To find the sales tax, you would multiply 0.08(90)

0.08(90)=7.2

In dollars, that would be $7.20

A lottery has a grand prize of 23 1/2 million dollars. There are 4 people who have winning tickets and they share this prize equ
UNO [17]

We should first convert 23 1/2 million dollars to a mixed number:

23\frac{1}{2}=\frac{47}{2}

Then we need to divide this by 4, since 4 people won an equal amount of the prize:

\frac{(\frac{47}{2})}{4}

And to solve this, we must multiply both the numerator and the denominator by \frac{1}{4}. This will then cancel out the 4 in the denominator:

\frac{47}{2}*\frac{1}{4}  =\frac{47}{8}

This is the amount each individual person won; we must convert this to a mixed number since the question asked us to:

\frac{47}{8}=5\frac{7}{8}

So now we know that each person won 5\frac{7}{8} million dollars.

The measures of the angles of a triangle are in the extended ratio of 3:7:10. What is the measure of the LARGEST angle?
Shkiper50 [21]

9514 1404 393

Answer:

  90°

Step-by-step explanation:

The ratio of the largest angle to the total is ...

  10/(3+7+10) = 10/20 = 1/2

The largest angle is half the total of all angles:

  1/2×180° = 90° . . . . measure of the largest angle
