Answer: [tex]8.66in^3[/tex]

Step-by-step explanation:

The oy rocket shown is formed by a rectangular prism and a regular pyramid whose base is a square.

The volume of the rectangular prism can be calculated with:

[tex]V_{rp}=l*w*h[/tex]

Where "l" is the length, "w" is the width and "h" is the height.

You can observe that:

[tex]l=8in\\w=1in\\h=1in[/tex]

Then, you can substitute values:

[tex]V_{rp}=(8in)(1in)(1in)=8in^3[/tex]

The volume of the regular square pyramid can be calculated with:

[tex]V_p=\frac{s^2*h}{3}[/tex]

Where "s" is the lenght of a side of the base and "h" is the height of the pyramid.

You can observe in the figure that:

[tex]s=1in\\h=2in[/tex]

Substitute into the formula. Then:

[tex]V_p=\frac{(1in)^2(2in)}{3}=\frac{2}{3}in^3[/tex]

The volume of the toy rocket is the sum of the volume of the rectangular prism and the volume of the regular square pyramid. Then:

[tex]V_{toy}=8in^3+\frac{2}{3}in^3=8.66in^3[/tex]

Answer:

For example, the function [tex]y=x^{2}[/tex] does not have a y-intercept of (0, 1). To prove this, let's make x=0, and if the value of 'y' is different from 1, then, the graph does nt have a y-intercept of (0,1):

[tex]y=x^{2}[/tex] ⇒ [tex]y=(0)^{2}[/tex] ⇒ [tex]y=0[/tex]

Therefore, the y-intercept is at (0, 0) not (0, 1).

Answer:

Option a

Step-by-step explanation:

A function is a relationship between two sets called domain and co domain  where there is one output for every input. If you have more than one output for a particular input, i.e. if the mapping of elements of A to B are not unique,  then the quantities represent a relation. A graph of a relationship can be shown to be a function using the vertical line test, which says that at any point if a vertical line makes two intercepts of the curve, the curve cannot be a function.

Given are two sets with {1,2,3,4,5,6} and {2,3,4,5,6,7} where there is a mapping.

We find that while 1,3 have unique mappings 2 does not have an image at all while 4 and 5 have the same image.

Since there is an element in the I set which does not have an image, this cannot be a function.

Option a

Answer:

2.61 : 3 = 0.87

To find the cost of one bag of crisps, subtract the change from the amount paid for the biscuits to find the cost of the biscuits in pence, then divide by three since three bags of crisps cost the same as one pack of biscuits. The cost of one bag of crisps is 87 pence.

The student is asking for the cost of one bag of crisps in pence, given that three bags cost the same as one pack of biscuits. Tom paid the shopkeeper £3 for a pack of biscuits and received 39p as change.

First, we calculate the actual cost of the biscuits:

£3 paid - £0.39 change = £2.61 or 261p (since 1 pound equals 100 pence)

Next, we know that this cost is equal to three bags of crisps, so:

261p / 3 bags = 87p per bag

Therefore, the cost of one bag of crisps is 87 pence.

Answer:

Step-by-step explanation:

Mary worked for 30 hours. This is calculated by first determining how many lamps Mia assembled, then subtracting this from the total to find out how many lamps Mary assembled. Finally, we divide the number of lamps assembled by Mary by her rate to find out how many hours she worked.

The question requires us to find out how many hours Mary worked if we know that together, Mary and Mia assembled 600 lamps, Mary assembles 10 lamps per hour, Mia assembles 12 lamps per hour, and Mia worked for 25 hours.

First, we can determine how many lamps Mia assembled by multiplying her working hours by her rate, resulting in 300 lamps (12 lamps per hour * 25 hours).

Next, we subtract the number of lamps assembled by Mia from the total to find how many lamps Mary assembled, resulting in 300 lamps (600 lamps total - 300 lamps assembled by Mia).

Finally, we can calculate how many hours Mary worked by dividing the number of lamps she assembled by her rate, resulting in 30 hours (300 lamps / 10 lamps per hour).

Are you asking what the 8 equal parts are ? If so 100/8=12.5

Dividing 100% into 8 equal parts means each part is 12.5% of the whole, showcasing a basic division of percentages.

The question "100% with 8 equal parts" involves dividing a whole into equal portions, which is a fundamental concept in mathematics. When we talk about 100% as being the whole, dividing it into 8 equal parts means we are essentially finding what 1/8th of this whole is, percentage-wise.

To calculate, we understand that 100% divided by 8 equals 12.5%. Therefore, each part of the 8 equal divisions of the whole is 12.5% of that whole. This is a simple percentage division problem and is relevant in understanding fractions, percentages, and their practical implications in everyday scenarios.

Answer:

The center of the circle is point (8 , 6)

Step-by-step explanation:

* At first lets revise how to find the mid-point between two points

- If (x1 , y1) and (x2 , y2) are the end point of a segment

- If (x , y) is the mid-point of this segment

- To find  x add x1 and x2, then divide the answer by 2

∴ x = (x1 + x2)/2

- Similar to find y add y1 and y2, then divide the answer by 2

∴ y = (y1 + y2)/2

∴ The mid-point (x , y) = [(x1 + x2)/2 , (y1 + y2)/2]

* Now lets solve the problem

- The center of the circle is the mid-point of the diameter

- Consider the center of the circle is (x , y)

- (x , y) is the mid-point of the diameter of the circle with endpoints

 (4 , 9) and (12 , 3)

- Let (4 , 9) is (x1 , y1) and (12 , 3) is (x2 , y2)

∵ x1 = 4

∵ x2 = 12

∵ x = (x1 + x2)/2

∴ x = (4 + 12)/2 = 16/2 = 8

* Similar

∵ y1 = 9

∵ y2 = 3

∵ y = (y1 + y2)/2

∴ y = (9 + 3)/2 = 12/2 = 6

∴ (x , y) = (8 , 6)

* The center of the circle is point (8 , 6)

Answer:

The center is (8,6) and radius is 5 units of the wheel

Step-by-step explanation:

On the design of the new car the steering wheel has a diameter with endpoints at (4 9) and (12,3)

End point of diameter is (4 9) and (12,3)

As we know mid point of diameter is center of circle.

Mid point formula:

[tex](x,y)\rightarrow (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

Mid point of  (4 9) and (12,3)

[tex]Centre: (\dfrac{4+12}{2},\dfrac{9+3}{2}[/tex]

Center: (8,6)

Radius is distance between center and any one end point of diameter.

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

[tex]R=\sqrt{(8-4)^2+(6-9)^2[/tex]

[tex]R=\sqrt{16+9}=\sqrt{25}[/tex]

Radius = 5

Hence, The center is (8,6) and radius is 5 units of the wheel

Answer:

9

Step-by-step explanation:

shorter leg = x

longer leg = x + 3

Hypotenuse = x + 6

x² + (x + 3)² = (x + 6)²

x² + x² + 6x + 9 = x² + 12x + 36

2x² + 6x + 9 = x² + 12x + 36

x²  - 6x  - 27 = 0

(x - 9) ( x + 3) = 0

x = 9 or x = -3 (rejected)

The length of the shorter leg of the right angles triangle is 9.

What is a right-angle triangle?

A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle. The right triangle or 90-degree triangle is another name for this triangle.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse

The right triangle's three sides are interconnected. The Pythagorean Theorem explains this connection. This theorem states that in a right triangle,  [tex]h^{2} = x^{2} + y^{2}[/tex];

where, h = hypotenuse; x = perpendicular side; y = base side;

Given that:

shorter leg = x

longer leg = x + 3

Hypotenuse = x + 6

⇒x² + (x + 3)² = (x + 6)²

⇒x² + x² + 6x + 9 = x² + 12x + 36

⇒2x² + 6x + 9 = x² + 12x + 36

⇒x²  - 6x  - 27 = 0

⇒(x - 9) ( x + 3) = 0

⇒x = 9 or x = -3.

x=-3 is not possible;

Hence, The length of the shorter leg = 9.
