Answer:

16

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh

A = 1/2 (4)*8

A = 16

Answer:

The area of the triangle is 16 cubic units

Step-by-step explanation:

The formula for the area of a triangle is like the same as a rectangle, just in half.  So, by doing 8x4, you get 32.  Divide 32 by 2 to get 16.

Answer:

C. Amount needed to fence around a circular garden

Step-by-step explanation:

The Circumference of a circle can be referred to as the length of the circle. It also called the perimeter of a circle.

The circumference of a circle can be defined as the distance roundabout a circle.

The circumference of a circle is calculated mathematically as:

a) 2πr or

b) πD

Where r = radius of the circle.

D = Diameter of the circle

From the above question, the situation can be modeled by circumference of a circle based on the definition that the circumference of a circle is the distance around a circle is Option C. "Amount needed to fence around a circular garden"

Answer:

3/10

Step-by-step explanation:

There are 10 sections

Number between 3 and 7 = 4,5,6 = 3 sections

P (number between 3 and 7) = sections between 3 and 7/ total

                                                 =3/10

Answer: 54 cm

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Perimeter of a square = side length x4

Replacing with the values given:

72 = 4 s

Solving for s (side length)

72/4=s

s = 18 cm

Since the side length of the square is the length of each rod, and all the rods have the same length, to obtain the perimeter of the triangle we have to apply:

Perimeter of an equilateral triangle: 3 side length

P = 3 (18 ) = 54 cm

Answer:

7x - 3y = -34

7x - 3(2) = -34

7x - 6 = -34

7x - 6 + 6 = -34 + 6

7x = -28

7x/7 = -28/7

x = -4

7(-4) - 3y = -34

-28 - 3y = -34

-28 + 28 - 3y = -34 + 28

-3y = -6

-3y/-3 = -6/-3

y = 2

Answer:

x = 4, y =5

Step-by-step explanation:

2x+5y=33.

3x-5y=-13

Add the two equations together to eliminate y

2x+5y=33.

3x-5y=-13

-------------------

5x = 20

Divide by 5

5x/5 = 20/5

x = 4

Now find y

2x + 5y = 33

2(4) +5y = 33

8+5y = 33

Subtract 8 from each side

8+5y-8 = 33-8

5y = 25

Divide each side by 5

5y/5 = 25/5

y = 5

Answer: 4y -12

Step-by-step explanation:

Let's take this step-by-step:

[tex]-\frac{2}{7}[/tex](-14y + 42)

Distribute the [tex]-\frac{2}{7}[/tex] to -14y and 42

[tex]-\frac{2}{7}[/tex]  * -14y = 4y

[tex]-\frac{2}{7}[/tex] * 42 = -12

We get

4y + (-12)

Simplify this to get:

4y -12

Answer:

The angle for each slice is 45 degrees.

Step-by-step explanation:

In order to calculate the angle of each slice, we first need to calculate the total area of the pizza, because we will use that to find the area of each slice and as a result it's angle. To calculate the area of the pizza we must use:

pizza area = pi*r²

r = d / 2 = 14 /2 = 7 inches

pizza area = pi*(7)² = 153.86 square inches

Since the pizza was divided in 8 pieces, the area of each piece is given by the area of the pizza divided by the number of slices. We have:

slice area = pizza area  / 8 = 153.86 / 8 =19.2325 square inches

Each slice is a circle sector, therefore it's area is given by:

slice area = (angle*pi*r²)/360

Therefore we can solve for angle:

19.2325 = (angle*pi*7²)/360

angle*pi*49 = 6923.7

angle = 6923.7 / pi*49 = 45 degrees

The angle for each slice is 45 degrees.

Step-by-step explanation:

The ladder forms a right triangle with legs of 8 and 3, and the ladder is the hypotenuse. Using the Pythagorean Theorem, we get that the ladder is about 8.5 meters long. Hope this helps!

Answer:

≈8.544

Step-by-step explanation:

The Pythagorean theorem says that [tex]a^{2} + b^{2} = c^{2}[/tex], where c is the ladder. Replacing the variables for numbers gives you [tex]3^2 + 8^2 = c^2.[/tex] Simplifying the right side gives you 9+64, or 73. Because [tex]c^2\\[/tex]=73, the answer is [tex]\sqrt{73}[/tex], or ≈8.544.

Answer:

(D)The first column is labeled x with entries 40, 160, 200. The second column is labeled y with entries 60, 15, 0.

Step-by-step explanation:

The piece-wise function, f(x) is defined as follows:

[tex]f(x)=\left\{\begin{array}{ccc}-\frac{5}{4}x+90 &0\leq x<40\\\\-\frac{3}{8}x+75 &40\leq x\leq 200\end{array}\right[/tex]

[tex]f(0)=-\frac{5}{4}*0+90=90\\\\f(16)=-\frac{5}{4}*16+90=70\\\\f(40)=-\frac{3}{8}*40+75=60\\\\f(120)=-\frac{3}{8}*120+75=30\\\\f(160)=-\frac{3}{8}*160+75=15\\\\f(200)=-\frac{3}{8}*200+75=0[/tex]

Therefore, the table which could represent the function is that which satisfies the points above.

In option D

[tex]\left|\begin{array}{c|c}x&f(x)\\--&--\\40&60\\160&15\\200&0\end{array}\right|[/tex]

Answer:

There are 29 chickens and 19 sheep.

Step-by-step explanation:

Samantha has chickens and sheep on her farm.

Let the number of chickens be c.

Let the number of sheep be s.

Each chicken has one head and each sheep has one head.

She looked out one day and counted 48 animal heads. Each chicken has one head and each sheep has one head.

This means that the number of chickens and sheep add up to 48:

c + s = 48 ____________(1)

She also counted 134 legs. Each chicken has one head and each sheep has one head. This means that:

2c + 4s = 134 ________(2)

From (1),

c = 48 - s ____________ (3)

Put (3) in (2):

2(48 - s) + 4s = 134

96 - 2s + 4s = 134

Collecting like terms:

2s = 134 - 96

2s = 38

s = 38 / 2 = 19

Putting this back in (3):

c = 48 - 19

c = 29

There are 29 chickens and 19 sheep.

Answer:

5.52 or less

Step-by-step explanation:

The total cost must be less than or  equal to the budget amount

Total cost limit  ≥ fee + cost per ticket * number of tickets

542.94 ≥  45.82 + cost per ticket * 90

Subtract 45.82 from each side

542.94 - 45.82≥  45.82 -45.82+ cost per ticket * 90

497.12 ≥ cost per ticket * 90

Divide each side by 90

497.12≥cost per ticket * 90

497.12/90≥  cost per ticket * 90/90

5.52 ≥  cost per ticket

Answer:

3/5

Step-by-step explanation:

P ( walks or takes the bus) = walks or takes the bus/ total

walks = 10

takes the bus = 25+ 20+5 = 50

There is no overlap

P ( walks or takes the bus) = walks or takes the bus/ total

                                             = (10+ 50)/ 100

                                             = 60/100
