Answer:
The area of the pentagon is approximately 21 square units
Step-by-step explanation:
The radius of the circle in which the regular pentagon is inscribed, r = 3
The area of a pentagon, 'A', inscribed in a circle with radius, r is given as follows;
A = 5×(1/2) ×2×r·sin(32°)×r·cos(32°) = (5/2)×r²×sin(72°)
Therefore, the area of the pentagon, A = (5/2)×3²×sin(72°) ≈ 21.3987716166 ≈ 21
The area of the pentagon, A ≈ 21 square units.
If the length of qr is 8 cm and the length of qs is 12 cm, what is the length of rs? No links Pls
Answer:
8.94
Step-by-step explanation:
Given that
qs = 12cm
qr = 8cm
Required
rs
Using the pythagoras theorem
Let us assume qs is the hypotenuse side
qs² = qr² + rs²
12² = 8² + rs²
144 = 64 +rs²
rs² = 144 - 64
rs² = 80
rs = √80
rs = 8.94
Hence the value of rs is 8.94
Find the measure of the arc TDB in the circle P shown below:
[tex]\huge{ \mathfrak{ \underline{ Answer \: \: ✓ }}}[/tex]
The Angle formed by an arc on the centre of the circle is double the angle made by the same arc on the circumference of the circle.
So,
[tex] \boxed{ \mathrm{ \angle TDB = \dfrac{1}{2} \angle TPB }}[/tex]
[tex] \mathrm{\angle TDB = \dfrac{1}{2} \times 90 \degree}[/tex][tex] \mathrm{\angle TDB =45 \degree } [/tex]_____________________________

If x = 9 when y = 36 and x is directly
proportional to y, what is x when y= 6?
Answer:
[tex]x = 1.5[/tex]
[tex]Explaination :\\\frac{36}{9} = 4\\\frac{6}{4} =1.5\\Answer = 1.5[/tex]
Answer:
x = 1.5
Step-by-step explanation:
[tex]\frac{9}{36} :\frac{x}{6}[/tex]
Cross multiply.
36 · x = 9 · 6
Simplify.
36x = 54
Divide each side by 36.
36x ÷ 36 = 54 ÷ 36
Simplify.
x = 1.5
what is the value of (-35) • (-5/7)
Answer:
56
Step-by-step explanation:
25
We'll start by getting rid of the negatives, because a negative times a negative equals a positive.
Multiply the whole number by the numerator first, then divide by the denominator.
35 x 5 = 175
175/7 = 25
Which answer choice represents the difference of 20 and 3 times a number?
A. 3j + 20
B. 20(3j)
C. 20 – 3j
D. (20 · 3)j
Answer:
C
Step-by-step explanation:
The word “difference” tells us that this is a subtraction problem
the words “three times a number” tells us that the variable will be multiplied by three
therefore it is C, 20-3j

Answer:
a = 105 in²
Step-by-step explanation:
Front and back, triangles
a = 2 * (1/2)(5 * 6)
a = 30
Sides, squares
a = 3 * (5 * 5)
a = 75
Total
a = 30 + 75
a = 105 in²

Aisha and some friends are going to the movies. At the theater, they sell a bag of
popcorn for $3.75 and a drink for $5. How much would it cost if they bought 5 bags of
popcorn and 8 drinks? How much would it cost if they bought p bags of popcorn and
d drinks?
Answer:
price of 5 bags of popcorn = 3.75 x 5 = 18.75
price of 8 drinks = 5 x 8 = 40
price of p bags of popcorn = 3.75 x p
price of d drinks = 5 x d
Caity is 50 inches tall. Caity's brother Michael is 5 inches taller than she is. What is Michael's height in feet and inches?
Answer:
55 inches = 4 feet 7 inches
Step-by-step explanation:
Because Michael is 5 inches taller so 50+5=55, then divided by 12 = 4 remainder 7. So that means Michael is 55 inches tall, or 4 feet and 7 inches
What is the area of the figure? (PLSSS HELP QUICKLY!!)
Answer:
416 cm^2
Step-by-step explanation:
The formula for the area of a trapezoid is:
[tex]\frac{(b1+b2)*h}{2}[/tex]
where b1 and b2 are the bases and h is the height. We can plug what we have into the formula:
[tex]\frac{(14 + 38)*16}{2}[/tex]
[tex]\frac{(52)*16}{2}[/tex]
[tex]52*8[/tex]

The sum of the ages of Mark, Tim and Jane is 39. In 5 years, the ratio of Mark's

13
20
Answer:
A. 15
Step-by-step explanation:
10 : 9 : 8
Mark: 10x
Tim: 9x
Jane: 8x
(10x - 5) + (9x - 5) + (8x - 5) = 39
10x - 5 + 9x - 5 + 8x - 5 = 39
27x - 5 - 5 - 5 = 39
27x - 15 = 39
27x - 15 + 15 = 39 + 15
27x = 54
27x ÷ 27 = 54 ÷ 27
x = 2
Mark: 10x - 5
10x - 5
10(2) - 5
20 - 5

a man has been driving a second hand car for the past four years. over these four years he managed to save 16% as a deposit of the price of the brand new car he wants to buy. the price of the new car is 750 000... calculate the amount he saved for the deposit
Answer:
$120,000
Step-by-step explanation:
Provided that
The price of the new car is $750,000
And, the saving percent is 16%
We need to calculate out the saving amount for the deposit
Therefore, the saving amount is
= $750,000 × 16%
= $120,000
Basically we multiply these two things to each other in order to get the saving amount

fractions are equal to 12 /18 is
Answer:
2/3
Step-by-step explanation:
Answer:
2/3 = 4/6 = 6/9 = 8/12
= 10/15 = 12/18 = 14/21 = 16/24
= 18/27 = 20/30 = 22/33 = 24/36
= 26/39 = 28/42 = 30/45 = 32/48
= 34/51 = 36/54 = 38/57 = 40/60
= 42/63 = 44/66 = 46/69 = 48/72
= 50/75 = 52/78 = 54/81 = 56/84
= 58/87 = 60/90 = 62/93 = 64/96
= 66/99 = 68/102 = 70/105 = 72/108
= 74/111 = 76/114 = 78/117 = 80/120
= 82/123 = 84/126 = 86/129 = 88/132
= 90/135 = 92/138 = 94/141 = 96/144
= 98/147 = 100/150 = 102/153 = 104/156
= 106/159 = 108/162 = 110/165 = 112/168
= 114/171 = 116/174 = 118/177 = 120/180
= 122/183 = 124/186 = 126/189 = 128/192
= 130/195 = 132/198 = 134/201 = 136/204
= 138/207 = 140/210 = 142/213 = 144/216
= 146/219 = 148/222 = 150/225 = 152/228
= 154/231 = 156/234 = 158/237 = 160/240
= 162/243 = 164/246 = 166/249 = 168/252
= 170/255 = 172/258 = 174/261 = 176/264
= 178/267 = 180/270 = 182/273 = 184/276
= 186/279 = 188/282 = 190/285 = 192/288
= 194/291 = 196/294 = 198/297 = 200/300

A fair die is rolled once. Let A be the event of rolling an even number, and let B be the event of rolling a number greater than 3. Find A ∩ B
Answer:
A ∩ B = {4, 6}
Step-by-step explanation:
A die had 6 faces
S = {1, 2, 3, 4, 5, 6}
If A be the event of rolling an even number, then;
A = {2, 4, 6}
If B be the event of rolling a number greater than 3, then;
B = {4, 5, 6}
A ∩ B are the values that are common to both sets
A ∩ B = {4, 6}
