Answer:

12.56 in²

Step-by-step explanation:

Area = πr²

Substitute for pi.

A = 3.14 × r²

The diameter is 4. We divide the diameter by 2 to get the radius.

4 ÷ 2 = 2

Substitute for the radius.

A = 3.14 × 2²

Solve

A = 3.14 × 4 = 12.56 in²

School bag _ y

book _ x

system:

y+3x=180

y+5x=270

y=180-3x (and we put that instead of 'y' in the second equation)

(180-3x)+5x=270

180+2x=270

2x=90

x=45

so one book costs $45

and school bag:

y+3×45=180

y+135=180

y=180-135

y=45

Answer:

Each book costed 45$.

Step-by-step explanation:

Let x represent the price of a school bag and y represent the price of a book.

we get the following system of equations:

x+3y=180  (equation 1)

x+5y=270 (equation 2)

using equation 1: x=180-3y

then we substitute x in equation 2 in order to find y:

180-3y+5y=270

180+2y=270

2y=270-180=90

y=90/2=45

and we know that y represents the price of a book, so each book costs 45$.

Answer:if a triangle is a right triangle, then the sum of the squares of the lenghts of the legs is equal to the square of the length of the hypotenuse.

- a property of all triangles with a right-angle (an angle of 90°)

Step-by-step explanation:

Zach is trying to find out the hypotenuse value of the right-angle triangle.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

The Pythagorean theorem states that "in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides".

Zach is most likely trying to find the length of the hypotenuse of a right triangle, which is the side opposite the right angle, given the lengths of the other two sides.

In this case, given 32 inches, 20 inches, and 20 inches values, he's trying to find out the hypotenuse value of the right-angle triangle.

Step-by-step explanation:

l = 12 metres

b = 15 metres

diameter of semicircle = length = 12 m

radius = 12/2 = 6 cm

area of the figure = area of rectangle + area of semi circle

= l × b + πr²

= 12 × 15 + 3.14 × 6²

= 180 + 113.04

= 293.04 m²

The perimeter of the figure is 60.84 meters.

A rectangle is a quadrilateral with all four interior angles 90°.

Given that, the width and height of the rectangle are 15 meters and 12 meters respectively.

Note that the diamter o he semicircel is 12 meters.

The radius of the semicircle is:

12/2

= 6 meters

The perimeter of the figure is given by:
15 + 12 + 15 + π(6)

= 42 + 3.14×6

= 60.84

Hence, the perimeter of the figure is 60.84 meters.

a) one unit up = Ix + 2I + 1

b) one unit down = Ix + 2I - 1

c) one unit to the left = Ix + 1I

d) one unit to the right = Ix + 3I

Let the function f(x) and g(x) are two real functions.

And g (x) = f (x) + k, where k is real numbers.

Function can be sketched by shifting f (x), k units vertically.

The direction of shift can be found by the value of k:

if k > 0, the base graph shifts k units up, and

if k < 0, the base graph shifts k units down.

The function provided by the basic function f(x) and the constant

g(x) = f(x - k),

may be drawn by horizontally moving the f(x) k unit coordinates.

The shift's direction depends on the value of k. Specifically,

The base graph moves k units to the right if k > 0, and

The base graph moves k units to the left if k < 0.

The graph of y = |x+2| is a V-shaped graph centered at x = -2.

To translate this graph, we need to modify the equation to shift it up/down or left/right.

Here are the equations for each translation:

a) To shift the graph one unit up, we need to add 1 to the equation:

y = |x+2| + 1

b) To shift the graph one unit down, we need to subtract 1 from the equation:

y = |x+2| - 1

c) To shift the graph one unit to the left, we need to replace x with (x+1) in the equation (since moving left means decreasing x by 1):

y = |(x+1)+2|

Simplifying this gives:

y = |x+3|

d) To shift the graph one unit to the right, we need to replace x with (x-1) in the equation (since moving right means increasing x by 1):

y = |(x-1)+2|

Simplifying this gives:

y = |x+1|

Therefore, all the required values are given above.

Step-by-step explanation:

According to the line plot, the 4 longest pieces of ribbon are :

Total length = Sum of the 4 pieces

1 hour

To solve this problem, we will need to use the unitary method.

Determining the equation:

⇒ 55 deliveries in 11 hours

⇒ 55 deliveries = 11 hours

Finding how much hours in 5 deliveries:

Divide both sides by x:

⇒ 55 deliveries = 11 hours

⇒ 55/x deliveries = 11/x hours

Simplify the numerators:

⇒ 55/x deliveries = 11/x hours

⇒ 5/x deliveries = 1/x hours

Use cross multiplication:

⇒ 5x deliveries = x hours

Divide both sides by x:

⇒ 5x/x deliveries = x/x hours

⇒ 5 deliveries = 1 hour

Answer:

1 hour

Step-by-step explanation:

let x = unknown number of hours

Set up ratios of deliveries to hours

[tex]\sf \implies 55 : 11 = 5 : x[/tex]

[tex]\sf \implies \dfrac{55}{11}=\dfrac{5}{x}[/tex]

Cross multiply:

[tex]\sf \implies 55x=5 \cdot 11[/tex]

[tex]\sf \implies 55x=55[/tex]

Divide both sides by 55:

[tex]\sf \implies x=1[/tex]

Therefore, 55 deliveries in 11 hours = 5 deliveries in 1 hour

Answer:

B

Step-by-step explanation:

If the first restaurant had 7 children within 42 customers, then we can divide 42 by 7 to get 6, which means 1 in 6 customers are children. If we apply this to the next restaurant, we will divide 60 by 6 to get 10.

This means there are 10 children in the second restaurant, so the answer is B.

p=15

Step-by-step explanation:

−955.5 = −955.5

Subtract 955.5 from both sides

31.5p=

\,\,472.5

31.5p

​ =

31.5

472.5

​Divide both sides by 31.5

p=15

​

The number of equation players the team can bring 15 players to the tournament.

Let's break down the information given in the problem:

Total amount raised: $1428

Cost of renting a bus: $955.50

Budgeted amount per player for meals: $31.50

To determine the number of players the team can bring to the tournament (represented by "p").

The total cost for the bus and meals calculated as follows:

Total Cost = Cost of Bus + (Cost per Player × Number of Players)

Using the given values, we can write this as an equation:

Total Cost = $955.50 + ($31.50 × p)

Now we can set up the equation using the total amount raised:

Total Amount Raised = Total Cost

Substitute the values:

$1428 = $955.50 + ($31.50 × p)

Now, let's solve for "p":

$1428 - $955.50 = $31.50× p

$472.50 = $31.50 × p

To isolate "p," divide both sides by $31.50:

p = $472.50 / $31.50

p = 15
