0.75*6 =4.5
4.5=4 1/2
Answer:
4 1/2 Hours is the amount she worked out
Step-by-step explanation:
3/4 = 45 min
45 x 6 = 270 min
270 ÷ 60 = 4.5 Hours
4.5 Hrs + 4 Hours 30 Min = 4 1/2
Translate the given phrase into an algebraic expression and simplify if possible: the difference of 10 and -18
Answer:
28
Step-by-step explanation:
10 - (-18) = x
10+18 = x (two negatives make a positive)
28 = x
The result of the given algebraic statement is 28.
Algebraic expressionsThe statement "the difference of 10 and -18" can be translated into an algebraic expression as follows:
10 - (-18)
To simplify this expression, we can simplify the double negative to have a positive sign as shown:
10 - (-18) = 10 + 18
Adding the numbers, we get:
10 - (-18) = 28
Therefore, the algebraic expression simplifies to 28.

x=4
Step-by-step explanation:
Since this is an equilateral triangle, all the sides are equal
6x = 4x+8 = 3x +12
Using the last 2 parts
4x+8 = 3x +12
Subtract 3x from each side
4x-3x +8 =3x+12-12
x+8 = 12
Subtract 8 from each side
x+8-8=12-8
x = 4

Step-by-step explanation:
3) first you have to find the inside of the angle. A straight line = 180*
180-(19x+3) = 177-19x
Than you add all the angles up to equal 180.
(177 - 19x) + (11x-2) + (9x+1) = 180
if you simplify this x = 4. You can check your answer by subbing in for x.
4)first you have to find the inside of the angle. A straight line = 180*
180- (17x-23) = 203-17x
Than add the sides up to equal 180. keep in mind there are 2 of the same angles.
(203-17x)+(7x+2)(2) = 180
Simplify
x=9
5) 180-151=29* this is the inner angle.
(11x-1)+(20x-3)+29=180
31x+25=180
x=5
a dog searching for a bone walks 3.5 m southeast, then 8.2 m at an angle 30 degrees north of east. Find the magnitude of the dog's resultant vector
The dog's resultant displacement vector, representing the total distance covered in the specified direction, is approximately 9.74 meters. This was calculated by breaking down each of the dog's movements into their Cartesian components, adding these components separately, and finally applying the Pythagorean theorem to find the magnitude of the resultant vector.
Explanation:To solve this problem, we first need to calculate each displacement in the rectangular (or Cartesian) coordinate system. Let's express each move of the dog as a vector.
First, the dog walks 3.5 m southeast. In the Cartesian coordinate system, this would be represented as two components: x (horizontal) and y (vertical). The x-component is 3.5*cos(45°) = 2.475 m and the y component is -3.5*sin(45°) = -2.475 m (negative because direction is south).
Second, the dog walks 8.2 m at an angle 30 degrees north of east. That gives us an x-component of 8.2*cos(30°) = 7.1 m and a y-component of 8.2*sin(30°) = 4.1 m.
Now add up separate x- and y-components: Our cumulative x-component is 2.475 m + 7.1 m = 9.575 m. The cumulative y-component is -2.475 m + 4.1 m = 1.625 m.
The resultant vector's magnitude can be determined with the Pythagorean theorem a² + b² = c² (where 'a' and 'b' are the legs and 'c' is the resultant vector). In this case: (9.575 m)² + (1.625 m)² = c². Solve for c to get
[tex]c = \sqrt{(9.575 \, \text{m})^2 + (1.625 \, \text{m})^2} = 9.74 \, \text{m}.[/tex]
In conclusion, the magnitude of the dog's resultant vector is approximately 9.74 m.

How would you explain surface area and volume to a 6th grader who is just now learning about these concepts?
Answer:
Surface area:
The area on the surface of a shape, so the area of the faces of the square or the area of the faces of the triangle.
(how to solve: find the area of all faces(b*h) and add them up)
Volume: the amount you can fill in that specific shape? Like, filling up a bathtub, how much water can it hold? That's volume.
(how to solve: its different for each shape, but squares are (B*W*H = Volume or V))

A regular octagon has side lengths of 9 units. Each side of the octagon is
increased by 27 units. What are the perimeters of the original octagon
and new octagon?
Answer:
The perimeter of the original octagon is:
72 units.The perimeter of the new octagon is:
288 units.Step-by-step explanation:
When it is mentioned that an octagon is regular, it means that all its sides are equal, therefore, each side of the original octagon has a length of 9 units, considering the formula of the octagon's perimeter:
Perimeter of an octagon = 8 * length.By replacing you get:
Perimeter of the original octagon = 8 * 9 = 72 units.For the new octagon, it is mentioned that each side increases by 27 units, therefore:
New length = 27 + 9 = 36 units.Applying the formula of perimeter of an octagon with the new values we obtain:
Perimeter of the new octagon = 8 * 36 = 288 units.Final answer:
The perimeter of the original octagon is 72 units, while the perimeter of the new octagon is 288 units.
Explanation:
An octagon is a polygon with eight sides. Since each side of the regular octagon has a length of 9 units, the perimeter of the original octagon is 8 times the length of one side, which is 8 x 9 units = 72 units.
When each side of the octagon is increased by 27 units, the new length of each side becomes 9 + 27 units = 36 units. Therefore, the perimeter of the new octagon is 8 times the length of one side, which is 8 x 36 units = 288 units.

A laundry basket has 24 T-shirts In it 4 are navy 12 are red and the remaining or white what is the probability of randomly selecting a red shirt
The probability of randomly selecting a red shirt from a basket of 24 T-shirts, where 12 are red, is 1/2 or 50%.
Explanation:The probability of randomly selecting a red shirt from the laundry basket can be calculated by dividing the number of red shirts by the total number of shirts in the basket. Given there are 24 T-shirts in total and 12 are red, the probability P(red) is 12 divided by 24, which can be simplified.
Here is the calculation:
Total number of T-shirts: 24Number of red T-shirts: 12Probability of selecting a red T-shirt: P(red) = Number of red T-shirts / Total number of T-shirts = 12 / 24After simplifying, P(red) = 1/2 or 50%.

Answer:
f(x) = [tex]3^x[/tex]
Step-by-step explanation:
This doesn't really look like a linear model, so it might be exponential.
Let's write the equation: y = a[tex]b^x[/tex]. Plug in a few values for y and x to find a and b:
9 = a[tex]b^2[/tex] ⇒ a = 9/b²
27 = a[tex]b^3[/tex] ⇒ a = 27/b³
Set these equal:
9/b² = 27/b³
9b = 27
b = 3
Plug this in to find a:
a = 9/b² = 9/9 = 1
The equation is:
f(x) = [tex]3^x[/tex]
Answer:
Y = 3^X
Step-by-step explanation:
this is an exponential function
Y = a(b^X)
9 = ab²
27 = ab³
b = 3
9 = a(3)²
a = 1
