What is the perimeter of the triangle?

Answer:

34.68 mm^2

19.23 ft^2

100.48 in^2

Step-by-step explanation:

Area of a circle = 0.5 x nr^2

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

0.5 x (9.4/2)^2 x 3.14 = 34.68

0.5 x (3.5)^2 x 3.14 = 19.23 ft^2

0.5 x (8)^2 x 3.14 = 100.48 in^2

Answer:

24

Step-by-step explanation:

Initially, there were 80 runners in the race. After the first half, 1/5 of them dropped out (given). Therefore, 4/5*80=64 runners remain. In the second half, 5/8 of these 64 runners drop out, meaning 3/8*64=24 runners finished the race.

Answer:

c

Step-by-step explanation:

The total surface area of a 3-dimensional object is the sum of the areas of the faces or surfaces of a 3 dimensional object

for example, the total surface area of a cube is the sum of the area of all the six faces

the total surface area of a cube = 6a²

where a = edge

if a = 6

total surface area

6(6²) = 216

Answer:

[tex]g(x)=\sqrt{-x}-1[/tex]

Step-by-step explanation:

Let's use the parent function [tex]f(x)=\sqrt{x}[/tex] as an example

Because we are flipping the radical function left, this means [tex]f(x)=\sqrt{-x}[/tex]

Because we are shifting down 1 unit vertically, we have [tex]g(x)=\sqrt{-x}-1[/tex]

Therefore, the final function is [tex]g(x)=\sqrt{-x}-1[/tex]

Answer:

Use formula

area of trapezium=(a+b)/2×h

Step-by-step explanation:

1)

area of trapezium=(a+b)2×j

as this u can calculate all of yr areas.

Answer:

f(x)= 25(1 + 0.20)^t

Step-by-step explanation:

The formula- f(x)= a(1+r)^x

a= initial amount (25)

r= growth rate (20%... 0.20)

x= # of times (we don't have that in here)

When you plug in the values, you get

f(x)= 25(1 + 0.20)[tex]{t}[/tex]

hope this helps!!

Answer:

option 1

Step-by-step explanation:

Using the recursive formula and a₁ = 6 , then

a₂ = 3 + 2a₁²

    = 3 + 2 × 6² = 3 + 2 × 36 = 3 + 72 = 75

Answer:

7

Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

Use the Intersecting chord theorem;

Rule: (CE) * (EB) = (AE) * (ED)

CE = x

EB = 15

AE = 9

ED = 10

=> (x) (15) = (9) (10)

15x = 90

Now Divide each side with 15

=> x = 6

Hope this helps!

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (6, 4)

m = [tex]\frac{4-8}{6-2}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1

Answer:

D

Step-by-step explanation:

A. 9x9 = 81

B. 2x2x2x2x2 = 32

C. 10x10 = 100

D. 5x5x5x5 = 625

Answer:

5⁴ has the greatest value

Step-by-step explanation:

9² = 9 x 9 = 81

2⁵ = 2 x 2 x 2 x 2 x 2 = 32

10² = 10 x 10 = 100

5⁴ = 5 x 5 x 5 x 5 = 624

Therefore, 5⁴ has the greatest value!

Step-by-step explanation:

Given the triangles A and B below :

Using trigonometric ratios :

If triangle A is given ;

Then ; MN will be obtained using the SIN relation :

Sin 20 = opposite (MN) / hypotenus (21)

If triangle B is given ;

Then ; MN will be obtained using the TAN relation :

Tan 20 = opposite (MN) / Adjacent (21)

Answer:

12 years

Step-by-step explanation:

The formula to solve the above question i.e to find the time is given as:

Equation:

t = (1/r)(A/P - 1)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.25%/100 = 0.0225 per year,

then, solving our equation

t = (1/0.0225)((12700/10000) - 1) = 12

t = 12 years

Therefore, if she does not add or withdraw from the account, the time it

will take to have a balance of 12,700 in her account is 12 years

Answer: 1,612 eggs

Step-by-step explanation:

Alex has a total of 806 dinosaurs. He also has twice as many eggs as he does dinosaurs.

The number of eggs is therefore:

= Number of dinosaurs * 2

= 806 * 2

= 1,612 eggs
