A quadrilateral is circumscribed about a circle. The sum of the lengths of its two opposite sides is 21 cm, and the radius of the circle is 5 cm. Find the area of the quadrilateral.
I will give 100 points
Answer:
105 cm²
Step-by-step explanation:
Properties of a quadrilateral circumscribed about a circle
Each side of the quadrilateral is a tangent to the circle.The sums of the measures of the opposite sides of the quadrilateral are equal. The area of the quadrilateral is half the product of its perimeter and the radius of the circle.Given:
Radius = 5 cmSum of the lengths of its two opposite sides = 21 cmTherefore, the sum of the other pair of opposites is also 21 cm.
So the perimeter = 21 + 21 = 42 cm
[tex]\implies \sf Area=\dfrac12\cdot42\cdot5=105\:cm^2[/tex]
Looking like trapezoid
area:-
1/2(sum of parallel sides)(Height)1/2(21+21)(5)1/2(42)(5)21(5)105cm²Each of the equal sides of an isosceles triangle is 5 inches more than twice the third side. If the perimeter of the triangle is 55 inches, find the sides of the triangle
Answer:
9 23 23
Step-by-step explanation:
Two sides are equal and are each 2x + 5 ( x = third side)
add the three sides to get 55 inches
2x + 5 + 2x+5 + x = 55
5x = 45
x = 9 so the sides are 9 and 23 and 23

Step-by-step explanation:
Surface area of rectangular prism:
Here, area of the top of the prism is not included.
l = 24 in ; b = 20 in ; h = 16 in
Surface area = lb + 2bh + 2lh
= 24 * 20 + 2*20*16 + 2*24 *16
= 480 + 640 + 768
= 1888 sqaure inches
Surface area of triangular prism:
length = 24 in ; a = b = 16 in ; base = 20 in and height = 13 in
[tex]\sf \text{Base area=$2*\dfrac{1}{2}*base *height = base *height$}[/tex]
= 20 * 13
= 260 square inches
Surface area = length*(a +b) + base area
= 24*(16+16) + 260
= 24 * 32 + 260
= 768 + 260
= 1028 square inches
Surface area of composite figure = 1888 + 1028
= 2916 square inches

It took a car 3 days to travel 3106 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answer:
43 mph
Step-by-step explanation:
1 day = 24 hours
3 days = 3 × 24 hours = 72 hours
The car taveled 3106 miles in 72 hours.
average speed = distance/time
average speed = (3106 miles)/(72 hours)
average speed = 43 mph
Answer: 43 mph
Explanation:
3 days is 72 hours.
R=D/T
Divide 3106 by 72
= 43 (rounded)
I really need help understanding when/ what situations to use sine rule and cosine rule with triangles, plssss.
thank you :)))
Answer:
See below :)
Step-by-step explanation:
If you want a missing angle or side in one pair, and you have at least one side and angle pair, use the sine rule.
If you want a remaining side, and you have the other two sides and the angle opposite the unknown side, use the cosine rule.
If you want an angle, and you have all three sides, use the cosine rule rearranged for angles.

Using technology, we found that Juan's investment account can be modeled by the function, c(x)=3x2-2x+10, in
thousands of dollars. What was Juan's initial investment?
O $5
o $10
o $5,000
$10,000
Answer:
$10
Step-by-step explanation:
"Initial" here means "beginning." That is, time = x = 0. If we let x = 0 here we get c(0) = 10, which is the desired answer. Juan's initial investment was $10.

What is parallel line in linear equation in two variables?
If the lines are parallel, there is no solution for the pair of linear equations. If there is no solution of the given pair of linear equations, the equations are called inconsistent.
As we know the condition for two parallel line given by the equation
[tex]a_1 x+b_1y+c_1=0\\a_2x+b_2y+c_2= 0[/tex]
is:
[tex]\frac{a_1}{a_2} \; = \; \frac{b_1}{b_2}[/tex] ≠ [tex]\frac{c_1}{c_2}[/tex]
We have the given equation as 2x + 5y =8
the equation which is parallel to 2x + 5y= 8 be
B) [tex]y= -\frac{2}{5} x+4[/tex]
5y = -2x +20
2x+5y=20
So, it satisfies the condition [tex]\frac{a_1}{a_2} \; = \; \frac{b_1}{b_2}[/tex] ≠ [tex]\frac{c_1}{c_2}[/tex]
Rest of the equation aren't satisfying the condition [tex]\frac{a_1}{a_2} \; = \; \frac{b_1}{b_2}[/tex] ≠ [tex]\frac{c_1}{c_2}[/tex].
Hence the line parallel to 2x+ 5y =8 is [tex]y= -\frac{2}{5} x+4[/tex].

The error which Loren made was C. she should have solved 149 = startfraction 19 over 9 endfraction (10) b for b.
What is an Error?This refers to those miscalculations or misjudgments about a situation or a mathematical solution to give wrong values.
Hence, because Loren is solving an equation of 0 = startfraction 19 over 9 endfraction (149) b for b to find the equation of a trend line that passes through the points (1, 130) and (10, 149), the error she made was option C.

A 12 foot ladder is resting against a wall. The base of the ladder is 2.8 feet from the base of the wall.How high up the wall will the ladder reach? Show all work and round to the nearest tenth.
Answer:
≈11.7 [ft].
Step-by-step explanation:
1) the ladder and the wall form the right triangle, where the length of the ladder (12 ft) is hypotenuse and the distance between the base of the latter and the base of the wall is the shortest side.
2) the longest side can be calculated according the Pythagoras theorem:

Well all you have to do is use this formula
75 + 36x -3 = 180
How did I figure that out?? Well I know that the angle next to 75 is the same as 36x-3 becuase that are alternate interior angles and 75 and 36x-3 would be a linear pair meaning that the product of the them would be 180, Thus making the formula
Now all you have to do is combine like terms:
75 -3 = 72
72 + 36x = 180
subtract 72 from both sides
72 -72 = 0
180- 72 = 108
36x = 108
divide both sides by 36

The measure of the angle ∠ABC is 110° and the measure of the reflex angle ∠CBD is 70°.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
The measure of the angle ABC will be
∠ABC = 110°
The angle ∠ABC and ∠CBD are the linear angles. Then we have
∠ABC + ∠CBD = 180°
110° + ∠CBD = 180°
∠CBD = 70°

12/35
1/35
2/75
3/70
The probability that Ned will choose 2 red shirts randomly from the box is 1/35.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of choosing 2 red shirts randomly from the box can be calculated using the formula for probability of independent events:
P(choosing 2 red shirts) = P(choosing 1st red shirt) × P(choosing 2nd red shirt after 1st red shirt has been removed)
The probability of choosing the first red shirt is 3/15 (since there are a total of 15 shirts in the box, of which 3 are red).
After one red shirt is removed, there will be 2 red shirts and 14 shirts remaining in the box.
Therefore, the probability of choosing the second red shirt is 2/14.
P(choosing 2 red shirts) = (3/15) * (2/14) = 1/35
Therefore, the probability that Ned will choose 2 red shirts randomly from the box is 1/35.
