Answer:
Step-by-step explanation:
1) the complete squares of the picture are 12, if we unite the other we can reach 15 squares circa
15 * 50 = 750 square units
3) Area = base x height = 12 * 9 = 108 cm^2
4) Area = (base x height)/2 = (24 * 16)/2 = 192 in^2
6) Area of the square = side ^ 2 = 12^2 = 144 cm^2
height of the triangle = 20 - 12 = 8 cm
Area of the triangle = (base x height)/2 = (12 * 8)/2 = 48 cm^2
Total area = 144 + 48 = 192 cm^2
7) radius = diameter / 2 = 20 : 2 = 10 cm
circumference = radius * 2 * pi = 20 * pi = 62.8 cm
area = radius^2 * pi = 100 * pi = 314.2 cm^2
10) √25 = 5
we have to find a positive number that multiply by itself gives 25
12) √100 = 10
we have to find a positive number that multiply by itself gives 100
15) √64 = 8
we have to find a positive number that multiply by itself gives 64

Use the function h(t) = -167 + C, where
t is the number of seconds and c is the
height of the bridge. How high above the
ground is a ball that was dropped off a
260-foot-high bridge after 2 seconds?
A O feet
B 64 feet
C 196 feet
Answer:
Ball distance from ground = 74 feet
Step-by-step explanation:
Given function;'
h(t) = -167(t) + C
t = number of seconds
c = height of the bridge
Find:
Ball distance from ground
If,
c = 260-foot-high bridge
t = 2 seconds
Computation:
h(t) = -167(t) + C
h(2) = -167(2) + 260
h(2) = -334 + 260
h(2) = -74
Ball distance from ground = 74 feet

13. If you have ₹ (100 3 ‒ 5x + 3) in your wallet, you got a gift of ₹ (10 3 + 3x) and you spent ₹ (80 3 ‒ 2 2 +9) in buying food, how much money is left in your pocket?
Answer:
10x³+2x²-8x-6
Step-by-step explanation:
Total amount = ₹ (100x³ ‒ 5x + 3)
Amont spent in gift = ₹ (10x³ + 3x)
Amount spent in buying food = ₹ (80x³ ‒ 2x² +9)
Left amount = Total amount - (Amount spent in gift+Amount spent in buying food)
= (100x³ ‒ 5x + 3)- [(10x³ + 3x)+(80x³ ‒ 2x² +9)]
= (100x³ ‒ 5x + 3)-(10x³ +3x+80x³ ‒ 2x² +9)
= 100x³ ‒ 5x + 3-10x³-3x-80x³ +2x²-9
= 10x³+2x²-8x-6
Hence, this is the required solution.
A plant costs p dollars and a bush costs b dollars. Ana buys 2 plants and 4 bushes for $42. Paola buys 7 plants and 9 bushes for $107. Write down a pair of simultaneous equations and solve them to find out the value of p and the value of b.
Answer:
p = 5 and b = 8
Step-by-step explanation:
First, create a system of equations:
2p + 4b = 42
7p + 9b = 107
Solve by elimination by multiplying the top equation by -7 and the bottom equation by 2:
-14p - 28b = -294
14p + 18b = 214
Add these together, and solve for b:
-10b = -80
b = 8
Plug in 8 as b into one of the equations, and solve for p:
2p + 4b = 42
2p + 4(8) = 42
2p + 32 = 42
2p = 10
p = 5
So, p = 5 and b = 8
Answer:
p = 5 and b =8
Step-by-step explanation:
2p + 4b = 42
2p = 42 - 4b
p = 21 - 2b
7p + 9b = 107
7 (21 - 2b) + 9b = 107
147 - 14b + 9b = 107
147 - 5b = 107
-5b = -40
b = 8
2p + 4 * 8 = 42
2p + 32 = 42
2p = 10
p = 5

c) 2.4 divided 0.3
d) 32 divided 0.16
Answer:
a) 50
b) 400
c) 8
d) 200
Step-by-step explanation:
a) 5 divided 0.1
[tex]\frac{5}{0.1} = \frac{5 \times 10}{0.1 \times 10} = \frac{50}{1} = 50[/tex]
b) 8 divided 0.02
[tex]\frac{8}{0.02} = \frac{8 \times 100}{0.02 \times 100} = \frac{800}{2} = 400[/tex]
c) 2.4 divided 0.3
[tex]\frac{2.4}{0.3} = \frac{2.4 \times 10}{0.3 \times 10} = \frac{24}{3} = 8[/tex]
d) 32 divided 0.16
[tex]\frac{32}{0.16} = \frac{32 \times 100}{0.16 \times 100} = \frac{32 \times 100}{16} = 200[/tex]

What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the trigonometric equation be represented as A
Now , the value of A is
sin ( x ) = sec ( x ) be equation (1)
On simplifying the equation , we get
sin ( x ) = 1 / cos ( x )
Multiply by cos ( x ) on both sides of the equation , we get
sin ( x ) cos ( x ) = 1
Now , the value of the trigonometric equation sin ( 2x ) = 2sin ( x ) cos ( x )
So , Substituting the values in the equation , we get
2sin ( x ) cos ( x ) / 2 = 1
sin ( 2x ) / 2 = 1
Multiply by 2 on both sides of the equation , we get
sin ( 2x ) = 2
Now , The range of sine is −1 ≤ y ≤ 1
So , there is no solution for the equation
Hence , the solution to the trigonometric equation is none

hey, another math question
Answer:
Step-by-step explanation:
By adjacent interior angles theorem,
If a transversal line 'r' intersects two parallel lines 'm' and 'n' then the consecutive interior angles are supplementary.
a° + (3x - 18)° = 180°
a° = 180° - (3x - 18)°
By vertical angles theorem,
If two straight lines intersect each other at a point, opposite angles formed are equal in measure.
180° - (3x - 18)° = (5x - 10)°
(5x - 10) + (3x - 18) = 180
(5x + 3x) - (10 + 18) = 180
8x - 28 = 180
8x = 180 + 28
8x = 208
x = 26

In the figure, the area of the shaded region is 224π cm^2.
What is the value of x?
Answer:
6330,24
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
x is the radius of the inner white circle
The area of the whole circle is
A = πr² = π × 18² = 324π cm²
The area of the shaded region = 224π cm²
Then the area of the white circle = 324π - 224π = 100π
Area of white circle = πx² = 100π ( divide both sides by π )
x² = 100 ( take the square root of both sides )
x = [tex]\sqrt{100}[/tex] = 10
