Answer:
40 people came to the Center to hike
Step-by-step explanation:
30 people took classes
22 did bird watching
12 did both
to solve, take 12 and subtract it from each one:
⇒ 30 - 12 = 18
⇒ 22 - 12 = 10
18 people only took classes
10 people only did bird watching
12 people did both
18 + 10 + 12 = 40
Find the degree measure of the angle expressed by 11x-6.
Answer:
Won't it just be 60, because it's an equilateral triangle.
Step-by-step explanation:
60 + 60 = 120
180 - 120 = 60
11x - 6 = 60
11x = 66
x = 66/11
x = 6
Let's substitute.
11(6) - 6 = 66 - 6 = 60
The city was painting a 6 mile section of street. On the first day the painted 2 1/6 miles. On the second day they painted 1 2/3 miles. How much would they have to paint on the third day to complete the painting job?
Answer:
[tex]2\frac{1}{6}[/tex]
Step-by-step explanation:
→ Add the distances painted
[tex]2\frac{1}{6} +1\frac{2}{3} =2\frac{1}{6} +1\frac{4}{6} =3\frac{5}{6}[/tex]
→ Minus from 6 to find the third day's work
[tex]6-3\frac{5}{6} =\frac{6}{1} -\frac{23}{6} =\frac{36}{6} -\frac{23}{6} =\frac{13}{6} =2\frac{1}{6}[/tex]

A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?
Answer:
1540
Step-by-step explanation:
First find the new price after the markup
The markup is
770 * 150%
770 * 1.5
1155
Add this to the original price
770 + 1155
1925
Now find the discount
1925*20%
1925*.20
385
Subtract this amount from the 1925
1925-385
1540
The final price is 1540
Answer:
Solution given:
cost price [c.p] of TV =$770
MP=c.p+ 150% of c.p=$770+150/100×770=$1925
discount [D]=20%
now
discount amount=D% of MP=20/100×1925=$385 is your answer.
$385 was the discount price on the plasma screen TV.
Apple juice and cranberry juice have been mixed in the ratio of 4:5. If the price of apple juice is 45 cents per pint and the price of cranberry juice is $0.8 per pint, what should the price of one pint of the mixture be?
Answer:
$0.24
Step-by-step explanation:
The computation of the price of the one pint of the mixture is shown below:
Since the ratio of apple juice and cranberry juice is 4:5
And, the price of apple juice is 45 cents i.e. = 0.45 × 4 ÷ 9 = 0.2
Also the price of cranberry juice is $0.8 = $0.08 × 5 ÷ 9 = 0.04
SO, the price of one pint of the mixture is
= 0.2 + 0.04
= $0.24
Answer:
$0.24444

Evaluate.0.2 power of 4 =
Answer:
0.0016
Step-by-step explanation:
The expression 0.2 by the power of 4 when evaluated has a value of 0.0016
How to evaluate the expressionFrom the question, we have the following parameters that can be used in our computation:
0.2 by the power of 4
Express as an equation
So, we have
0.2 by the power of 4 = 0.2⁴
When expanded, we have
0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2
Evaluate the products
This gives
0.2 by the power of 4 = 0.0016
Hence, the solution is 0.0016

As an estimation we are told 5 miles is 8 km.
Convert 32.5 miles to km.
Answer:
52 km
Step-by-step explanation:
Given, 5 miles is 8km.
So, 1 mile will be (8/5) km.
Now, 32.5 miles will be (8/5) x 32.5 = 52 km
Find the volume of the regular hexagonal pyramid if the lateral edge is 15 feet.
Answer:
Volume of the given pyramid = 1122.37 cubic feet
Step-by-step explanation:
Volume of the regular hexagonal pyramid = [tex]\frac{1}{3}(\text{Area of the base})(\text{Base})[/tex]
Measure of internal angle of a polygon = [tex]\frac{(n-2)\times 180}{n}[/tex]
Here, n = number of sides of the polygon
For a hexagon, n = 6
Measure of interior ∠C = [tex]\frac{(6-2)\times 180}{6}[/tex]
= 120°
Measure of ∠BCD = [tex]\frac{120}{2}[/tex]
= 60°
By applying tangent rule in ΔCED,
tan(∠ECD) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(60°) = [tex]\frac{DE}{CE}[/tex]
[tex]\sqrt{3}=\frac{DE}{6}[/tex]
DE = [tex]6\sqrt{3}[/tex] feet
And cos(60°) = [tex]\frac{EC}{CD}[/tex]
[tex]\frac{1}{2}=\frac{6}{CD}[/tex]
CD = 12 feet
Area of ΔBCD = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(6\sqrt{3})(12)[/tex]
= [tex]36\sqrt{3}[/tex] feet
Area of hexagonal Base of the pyramid = [tex]6(36\sqrt{3})[/tex]
= 216√3 square feet
Since, lateral height of the pyramid (AC) = 15 feet
By applying Pythagoras theorem in ΔADC,
AC² = AD² + CD²
(15)² = AD² + (12)²
AD = [tex]\sqrt{225-144}[/tex]
AD = 9 feet
Volume of the given pyramid = [tex]\frac{1}{3}(216\sqrt{3})(9)[/tex]
= 648√3 cubic feet
= 1122.37 cubic feet

In the given diagram(see image) , TAX and TBY are tangents to the circle and C is a point on the major arc.
Question :
If <CAX = 65° , <CBY = 76° , Calculate <ATB.
Answer:
∠ATB = 102°
Step-by-step explanation:
Since ∠CBY is less than 90°, CB is not a diameter.
I did this in my head so I drew a sketch to show that around about way I did it. sketch attached:
I drew a third line from X to Y that is tangent to the circle at C.
Because each pair of tangent lines to a common point are equal, we have made three isosceles triangles.
Now we know 2 of the three angles to ΔXYT, 180 - 50 - 28 = 102° for ∠ATB
Answer:
102°Step-by-step explanation:
Given
∠CAX = 65° , ∠CBY = 76°To find
∠ATBSolution
Refer to attached picture
∠CAX= ∠CBA as same arc intercepted ∠CBY = ∠CAB as same arc interceptedTAX is a straight angle and:
∠TAB = 180° - (∠CAX + ∠CAB) = 180° - (65° + 76°) = 39°∠TBA = ∠TAB as two tangents intersect at same distance, their opposite angles are therefore same. ΔATB is an isosceles triangle.
∠ATB = 180° - 2*39° = 102°Jessie spent a total of 14.00 to purchase a gift and have it gift-wrapped and mailed. The cost for the postage was $2.25, and she knows the gift itself cost $9.50.

Answer:
Step-by-step explanation:
Perimeter of the given polygon = n + 2 + 3 + 4 + n + 2 + 3 + 4
= 2(n + 2 + 3 + 4)
= 2(n + 9) units
Area of the composite figure = Area of rectangle A + Area of rectangle B + Area of rectangle C
= (3 × 4) + (n ×2) + (2 × 3)
= 12 + 2n + 6
= 2n + 18
= 2(n + 9) units²
Therefore, perimeter of the given figure = Area of the figure

A string reaches from the top of a 17-foot pole to a point 13 feet from the base of the pole. To the nearest tenth of a foot, how long is the string?
Answer:
21.4 feets
Step-by-step explanation:
Using Pythagoras rule :
The length of the string:
Hypotenus = sqrt(opposite² + adjacent²)
Length of string = sqrt(17² + 13²)
Length = sqrt(289 + 169)
Length of string = sqrt(458)
Length of string = 21.400
Length = 21.4 feets
Write an equation that could be used to find the value of x using the interior angles of ∆BDC, then solve it.
9514 1404 393
Answer:
x = 16
Step-by-step explanation:
Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.
Using ∆ABD
55 +90 +2x+3 = 180
2x = 32 . . . . . . subtract 148
x = 16
Using ∆BCD
50 +90 +2x+8 = 180
2x = 32 . . . . . . subtract 148
x = 16
Using ∆ABC
55 +(2x +3) +50 +(2x +8) = 180
4x = 64 . . . . . . . subtract 116
x = 16

4/13
Answer:
Step-by-step explanation:
There are 13 hearts in 52 cards. C From above, P(Queen)=4/52 and P Heart=13/52, the queen of hearts is in both categories so we have to subtract 1/52 so we don't double count.
