Answer:

54 cubic inches?

Step-by-step explanation:

The Surface area of bar is 7696 square mm.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

We have,

The base was an equilateral triangle with a side of 16 mm and the bar was 155 mm long.

So, Surface area of Triangular Prism

= ( 16 + 16 + 16) 155 + 16  x 16

= 7440 + 256

= 7696 square mm

Answer:

D

Step-by-step explanation:

With each flip of the coin, the chance of it landing on tails is multiplied by half. Hence the chance of landing a consecutive series of tails decreases the more times you flip the coin, but never reaches 0.

A is incorrect as it is possible to land heads on any flip.

B is incorrect as there is always a possibility of landing tails on every flip.

C is incorrect as the chance of getting tails on every flip is small (and gets smaller) and hence cannot be considered to be likely.

Hence D is the answer.

Answer: $4.99

Step-by-step explanation:

The amount that Savannah paid for the 3 pairs of socks will be gotten by subtracting $5.03 from $20 which will be:

= $20 - $5.03

= $14.97

Since each paid of socks cost thesame amount, the cost of each pair of socks will be:

= $14.97/3

= $4.99

Each pair of socks cost $4.99

(a) Determine the total length of the circular portions in terms of

pi. Show the work that leads to your answer.

(b) Determine the total length of wire needed, both circular and

square portions, to the nearest tenth of an inch.

G

(c) Determine the total weight of the ornament to the nearest

gram.

Answer:

12π

53.68 in

96.624g

Step-by-step explanation:

The total length of the circular portion :

Perimeter of circle = Circumference of the circle = 2πr ; r = radius = 2

Size of each circle is 3/4

Number of circles = 4

Number of complete circles :

4 × 3/4 = 3 complete circles

Perimeter of circle:

Number of circles * (2πr)

3 * 2 * π * 2 = 12π

Total wore needed :

Circular + Square

Perimeter of square = 4s

s=side length = 4

Total square 4 * 4 = 16

Perimeter of Square + perimeter of circle

16 + 12π = 16 + (12 * 3.14) = 53.68 in

Total weight of ornament :

1.8 g * perimeter

1.8 * 53.68 = 96.624g

Answer:

The ball reaches 44 ft above the ground after 4 sec.

Step-by-step explanation:

Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t.  Indicate exponentiation with " ^ "

-16t^2 + 300 = 44 becomes

-16t^2 + 256 = 0, or 16t^2 = 256.  Then, taking the square root of both sides, we get:

4t = 16, or t = 4 sec.  The ball reaches 44 ft above the ground after 4 sec.

The ball will take 4 seconds.

A quadratic equation, or simply "quadratics," is a polynomial equation with a degree of two as its highest. This is how it is expressed:

a x² + b x + c = 0 where x is the unknown variable and the constant terms are a, b, and c.

Given equation of height h(t) = -16t² + 300...…..(1)

where h is height in feet and t is time in seconds,

and height at t = 0 is 300 feet

when ball is 44 feet above ground then time is,

put h = 44 in equation 1

44 = -16t² + 300

16t² = 300 - 44

t² = 256/16

t = √16

t = 4

Hence time taken by ball is 4 seconds.

A = 53° (Rounded to the nearest whole number)

Step-by-step explanation:

Since the angle needs to be found out and it's adjacent as well as hypotenuse is given we will used the Cosine ratio;

Cos(A) = [tex]\frac{26}{43}[/tex]

A = Cos⁻¹ ([tex]\frac{26}{43}[/tex])

Step-by-step explanation:

A circle graph also known as a pie chart is used to represent data graphically. the circle graph is made up of a circle that is divided into quadrants. Each quadrants represents different classifications of data and the proportion of each classification.

the sum of angles in a pie chart is 360 degrees while the total percentages is 100%.

If there are 25% of the students in a class each take maths, physics , biology and chemistry, the pie chart would be divided into 4 quadrants with each quadrant measuring 25%

Answer:

B

Step-by-step explanation:

its a right angle and one point is 40 as shown already so 90-40=50 hope this helps

So you would take your 90° angle which is the box on the bottom right hand corner and add 40° which would equal 130° and then you would subtract 180° -130° and you would get 50°.

Answer:

4,500

Step-by-step explanation:

150,000x.03=4500

The commission of the real estate agent is 4500 which is 3% of 150,000.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A real estate agent earns a 3% commission on each house she sells and she sells a 150,000 house.

So, His commission is 3% of 150,000.

Therefore,

Commission = (3/100)×150000.

Commission = 4500.

So, The commission of the real estate agent is 4500.

Answer:

there were 8 dog ears in all.

Step-by-step explanation:

Since the statement says that they saw two teachers each walking with two dogs, you have to multiply the number of teachers for the number of dogs each one had to find the total number of dogs they had:

2*2=4

Now, as the statement indicates that each dog had two ears you have to multiply the number of dogs for the number of ears each one has:

4*2=8

According to this, the answer is that there were 8 dog ears in all.

Answer:

78$

Step-by-step explanation:

3 adults, 2 dollars per adult. Multiply. 3(2) = 6

9 children, 8 dollars per child. Multiply. 9(8) = 72

Add to get total sum of money they needed to pay. 72+6 = 78

Answer:

0, -3

Step-by-step explanation:

So remember, when they say reflect over the x intercept, they do not mean to reflect the x value, they mean to reflect over the hirzontal line of the graph.(x axis)

This is the same with reflection over the y intrecept. This doesnt mean y is flipped, this means that whatever point or line you have is reflected over the vertical line on the graph(y axis)

So our orginal value is (0, 3). We need to reflect over the x axis, which means that y will now be -3, since that is the opposite of what we can see when we flip the x axis.

The 0 x, of course, stays the same since its 0.

So your answer is (0, -3)

Hope this helps! :)

Given:

The equation is:

[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]

To find:

The value of y.

Solution:

We have,

[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]

On cross multiplication, we get

[tex]y(p+q)=y(p-q)[/tex]

[tex]yp+yq=yp-yq[/tex]

[tex]yp+yq-yp+yq=0[/tex]

[tex]2yq=0[/tex]

Dividing both sides by 2q, we get

[tex]\dfrac{2yq}{2q}=\dfrac{0}{2q}[/tex]

[tex]y=0[/tex]

Therefore, the correct option is A.

Answer:

(-3,0)
