Answer:

62%

Step-by-step explanation:

34 girls like biology

? boys like biology

It is 34%≤

27% Prefer chemistry

11% prefer physics

27 + 11 = 38

100 - 38 = 62

let me know if i'm wrong

Answer:

64

Step-by-step explanation:

add them all up firstly to get 701

then divide by how many are there (11)

then you will get 63.72

and you need to round up since the decimal is a 7

which that gives you 64

Answer:

1) C: 113 m

2) C: 572.3 m²

3) B: 61.2 cm²

4) A: $2.2

6) C: 756 yd³

8) D: 3402 mm²

9) A: 25x + 125 < 500

Step-by-step explanation:

1) Formula for circumference of circle is;

C = 2πr

radius; r = 18 m

C = 2π × 18

C ≈ 113 m

2) Formula for area of a circle is;

A = πr²

Here we have diameter; d = 27

Thus, radius; r = 27/2 = 13.5 m

A = π × 13.5²

A = 3.14 × 13.5²

A ≈ 572.3 m²

3) The diameter of the semicircle is parallel to the base of the rhombus. Thus, diameter; d = 7 cm

Thus, r = 7/2 = 3.5 cm

Area of semi circle = ½πr² = ½ × π × 3.5² = 19.2 cm²

Area of rhombus = base x height = 7 × 6 = 42 cm²

Total area of object = 42 + 19.2 = 61.2 cm²

4) Cost of banana per pound = $0.4 per pound

Amount of banana bought = 5.5 pound

Amount spent = 0.4 × 5.5 = $2.2

6) Volume of triangular prism is;

V = ½bhl

b = 12 yd

h = 7 yd

L = 18 yd

Thus;

V = ½ × 12 × 7 × 18

V = 756 yd³

8) Volume of cuboid at the base;

V1 = lbh = 25 × 9 × 9 = 2025 mm²

Volume of cuboid at top;

V2 = 9 × 9 × 9 = 729 mm²

Volume of triangular prism;

V3 = ½bhl = ½ × 9 × 9 × (25 - 9) = ½ × 81 × 16 = 648 mm²

Total volume = 2025 + 729 + 648 = 3402 mm²

9) Cost per class; $25 per class

Charge for the supplies = $125

He doesn't want to spend more than $500.

Thus;

25x + 125 < 500

Answer:

1/12

Step-by-step explanation:

1/4 X 1/3 = 1/12

Answer:

1/12

Step-by-step explanation:

When multiplying fractions, you multiply it like normal numbers, so 1 is multiplied by 1, and 3 is multiplied by 4.

For example:

3/4 x 9/10 would be equal to 27/40 because the 3 is multiplied by 9 and 4 is multiplied by 10.

3 x 9 = 27

4 x 10 40

27/40

Therefore on your question it would be 1/12.

Answer:

32.9 degrees

Step-by-step explanation:

cos (x) = 21/25

cos^1 (21/25)

= 32.856 --> round to 32.9

Answer:

32.9°

Step-by-step explanation:

You can see that relative to the angle that is x, we are given the side lengths that are adjacent and the hypotenuse. The trig function associated with this is cosine, and we get:

cos(x) = adj / hyp --> 21 / 25

To find x as the angle, we use the function arccosine,

x = arccosine(21/25)

x = 32.85988038°

And this rounds up to 32.9°

Answer:

Number of bottles= 1,708

Step-by-step explanation:

Giving the following information:

Total liters= 35,874 litres

Bottle capacity= 21 liters

To calculate the number of bottles that can be filled given the actual capacity, we need to use the following formula:

Number of bottles= total liters / cottle capacity

Number of bottles= 35,874 / 21

Number of bottles= 1,708

Answer:

Student A

Step-by-step explanation:

Student a median: 33

Student b median: 32

student a

the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution

Answer:

y<=-3x-3

Step-by-step explanation:

m=y2-y1/x2-x1

m=-6-3/1-2

m=-3

y-y1=m(x-x1)

y-3=-3(x-(-2))

y-3=-3x-6

y=-3x-6+3

y=-3x-3

we change the equal sign to a "less than or equal to" sign to get the final answer of y <= -3x-3

Answer:

C = 25 + 3n

Step-by-step explanation:

Andre has a summer job selling magazine subscriptions.

We are told that:

Andy earns $25 per week plus $3 for every subscription he sells.

Let us represent

C = Total amount of money he makes this week

n = the number of magazine subscriptions Andre sells this week.

Hence, Our Algebraic expression =

C = $25 + $3 × n

C = 25 + 3n

Answer:

x ={-3, -4, -5 , -6, -7, ...}

Answer: 85.2

Step-by-step explanation:

The answer is correct because, to find your grades your bassicaly just looking for the mean. To find the mean you have to take all the numbers and add them after you do that you have to divide how ever much numbers you added. So in this case we do 90 plus 76 plus 88 plus 80 plus 92. That equals 426, and since we added five numbers we divide the answer by 5 and that equals 85.2.

Hope This Helps!

Answer:

Roots of the function are x = 2, 5.

Step-by-step explanation:

Roots of a function are defined by the x-intercepts of the graph.

From the given graph in the question,

x-intercepts → x = 2, 5

Now confirm it by solving the equation algebraically,

x² - 7x + 10 = 0

x² - 5x - 2x + 10 = 0

x(x - 5) - 2(x - 5) = 0

(x - 5)(x - 2) = 0

x = 2, 5

Therefore, roots of the function are x = 2, 5.

Answer: 37/100

Step-by-step explanation:

The fraction of a kilometer that he walked in all would be the sum of 27/100 and 1/10.

To add them, first find the lowest common multiple of both denominators. This number is 100 so will be the denominator.

Divide 100 by each denominator and multiply it by the numerator:

= (27 + 10) / 100

= 37/100

Note: 100/10 = 10

= 10 * 1 = 10 which is the second numerator.

Answer:

they look like their curved at about  70? 65? and they would be the same

Step-by-step explanation:

Answer: Both C and D are 76

Step-by-step explanation:

Because this is a isosceles triangle both C and D are the same. Subtract 28 from 180 and you get 152. So D and C combined equals to 152 so divide that by 2 an you get 76.

Answer:

[tex]150 km^{2}[/tex]

Step-by-step explanation:

Use the surface area equation of cylinder: [tex]A = 2\pi rh + 2\pi r^{2}[/tex]

The diameter is 6 km but you need the radius for the formula, so you divide the diameter by 2.

6÷2 = 3 --> r = 3

You already know h, aka the height.

Plug everything into the equation.

Answer:

150.72

Step-by-step explanation:

im usin 3.14 as pi btw

the term net means like imagine you unfold the shape like the walls of the shape are paper. its now a 2d net, which includes a rectangle and two circles.

so, surface area of a circle is pi r^2 so 3.14 * 3 * 3 = 28.26

times two cause theres two circles; top and bottom :3

56.52 = 28.26 * 2

rentangle surface area = h*l

the height of the rectangle is 5 and the length is the circumference of the circle

circumference is 2*3.14*r, which in this problem, is 3

2*3.14*3 = 18.84

now, h*l is 18.84*5 = 94.2

94.2 + 56.52 = 150.72
