Answer:

100 people

Step-by-step explanation:

In the attached image below we can see that the original survey was done on a total of 50 individuals (12 + 3 + 20 + 15 = 50). Out of these 50, 20 of them answered basketball.

20 / 50 = 0.40 ... multiply by 100 to get percentage

0.40 * 100 = 40%

We can see that this is 40% of the original survey sample population. If we use this same percentage, we can predict how many individuals out of 250 would answer basketball. We calculate this by multiplying 250 by 40% in decimal form, like so...

250 * 0.40 = 100

Finally, we can predict that 100 people would most likely answer basketball.

Answer:

12 units²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 4 ( perpendicular distance between the bases ) and

b₁ = SR = 2, b₂ = TA = 4 , then

A = [tex]\frac{1}{2}[/tex] × 4 × (2 + 4) = 2 × 6 = 12 units²

Answer:

9/10 divide by 1/5

4 1/2 cups

Step-by-step explanation:

Serving of dried fruits = 1/5 cups

Bag of dried fruits = 9/10 cups

Expression that can be used to find the number of servings in the bag = Bag of dried fruits / Serving of dried fruits

= 9/10 ÷ 1/5

= 9/10 × 5/1

= (9* 5) / (10 * 1)

= 45/10

= 4 5/10

= 4 1/2 cups

9/10 divide by 1/5

Answer:

150

Step-by-step explanation:

So if we rearrange the second equation we can get:

s = 190 - a

Now we substitute this into the first equation:

4a + 3(190 - a) = 720

4a + (570 - 3a) = 720

4a + 570 - 3a = 720

4a - 3a = 720 - 570

a = 150

Answer:

the answer is c

Step-by-step explanation:

Domain is [tex]{ x|x\neq -1,2,4}[/tex]

The domain of a function is the complete set of possible values of the independent variable.

The domain is the set of all possible x-values which will make the function "work", and will output real y-values

We need to find the domain of the function graphed

Domain are the values of x for which the function is defined.

For domain, we look at the x values of the graph.

We have graph for x values  the graph goes close to x = -1 and x = 4 axis but does not cross x = -1 and x = 4axis. and at x =2 not define

So , domain is set of all x values  [tex]{ x|x\neq -1,2,4}[/tex]

Hence, domain is [tex]{ x|x\neq -1,2,4}[/tex]

Answer:

L = 10m

And, W = 20m

Step-by-step explanation:

The computation is shown below:

Given that

2L + W = 40 m

Also we know that

Area = Length × width

= L × ( 40 - 2L)

= 40L - 2L^2

= -2(L^2 - 20L)

= -2(L^2 - 20L + 100 - 100)

= -2(L^2- 20L + 100) + 200

= -2(L - 10)^ + 200

So

L = 10m

And, W = 20m

Answer:

C

Step-by-step explanation:

Given

tanθ = [tex]\frac{1}{2}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle with legs 1 and 2

Using Pythagoras' identity

hypotenuse² = 1² + 2² = 1 + 4 = 5 ( take square root of both sides )

hypotenuse = [tex]\sqrt{5}[/tex]

θ is in the 3rd quadrant where sinθ < 0 , then

sinθ = [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{1}{\sqrt{5} }[/tex] ← rationalise the denominator

       = - [tex]\frac{1}{\sqrt{5} }[/tex] × [tex]\frac{\sqrt{5} }{\sqrt{5} }[/tex]

       = - [tex]\frac{\sqrt{5} }{5}[/tex] → C

Assuming the angle made by a vector refers to the angle it makes with the positive horizontal axis, take the dot product of u with the vector (1, 0), and recall that

a • b = ||a|| ||b|| cos(θ)

where θ is the angle made by the vectors a and b. Then

u • (1, 0) = ||u|| ||(1, 0)|| cos(θ)

We have

u • (1, 0) = 5×1 + 8×0 = 5

||u|| = √(5² + 8²) = √89

||(1, 0)|| = √(1² + 0²) = √1 = 1

so that

5 = √89 cos(θ)

cos(θ) = 5 / √89

θ = arccos(5 / √89) ≈ 57.99°

Answer:

1) 6447,55 unități pătrate

2) 25192,43 unități cubice

Step-by-step explanation:

1) Suprafața totală a unui cilindru

Formula = 2πr (r + h)

r = 27 de unități

h = 11 unități

Suprafața totală = 2 × π × 27 × (27 + 11)

= 6446.54813 unități pătrate

Aproximativ = 6447,55 unități pătrate

2) Volumul cilindrului

Formula = πr²h

= π × 27² × 11

= 25192,43 unități cubice
