Step-by-step explanation:
Dominic spent hours on his art project. Rachel worked times as long on her art project as Dominic worked. For how many hours did Rachel work on her art project?
Answer:
Rachel worked for [tex]3\frac{2}{3}[/tex] hours
Step-by-step explanation:
See comment for complete question
Given
Let
[tex]D = Dominic[/tex]
[tex]R = Rachel[/tex]
So:
[tex]D = 2\frac{3}{4}[/tex]
and
[tex]R =1\frac{1}{3}[/tex] as long as D
Required
Determine the number of hours spent by Rachel
This implies that:
[tex]R =1\frac{1}{3}[/tex] as long as D
Rewrite as:
[tex]R =1\frac{1}{3} * D[/tex]
Substitute: [tex]D = 2\frac{3}{4}[/tex]
[tex]R =1\frac{1}{3} * 2\frac{3}{4}[/tex]
Express as improper fraction
[tex]R =\frac{4}{3} * \frac{11}{4}[/tex]
This gives:
[tex]R =\frac{1}{3} * 11[/tex]
[tex]R =\frac{11}{3}[/tex]
Express as mixed numbers
[tex]R =3\frac{2}{3}[/tex]
Hence, Rachel worked for [tex]3\frac{2}{3}[/tex] hours
Find the surface area of the square pyramid, Show your work please : )
Answer:
105in²
Step-by-step explanation:
Surface area is the total area of the faces.
The faces of pyramid consist of triangles and a square
The area of a square can easily be calculated by squaring the side length
the square of this pyramid has a side length of 5
so
area of square = 5²
5² = 25
the area of the square is 25in²
Now to find the area of the triangles
All we have to do is find the area of one triangle and multiply that buy 4 ( because there are four triangle)
the area of a triangle can be calculated using this formula :
[tex]A=\frac{bh}{2}[/tex] where b = base and h = height
The triangles have a base length of 5 in and a height of 8 in
so
[tex]A=\frac{5*8}{2} \\5*8=40\\\frac{40}{2} =20\\A=20[/tex]
So the area of one triangle is 20 in²
Now we multiply 20 by 4 to find the area of all 4 triangles
20 * 4 = 80
So the total area of the triangles is 80in²
Finally we add the two areas together
Surface area = 80 + 25
80 + 25 = 105
Hence, the surface area is 105in²
Answer:
105 in.
Step-by-step explanation:
To find the area of a square pyramid, use this formula
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height.
The base is a square.
To find the area of a square, simply multiply the side length by itself twice (x^2).
5 x 5 = 25.
25 is the area of the base.
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height
25 + 1/2 ⋅ p ⋅ height.
To find the perimeter of a square, add every side length; the sum is the perimeter.
5 + 5 + 5 + 5 = 20.
20 is the perimeter of the square.
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height
25 + 1/2 ⋅ 20 ⋅ height
The height is the number along the little lines.
8 is the height.
Now that we have all parts of the formula, we have our final equation.
a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height
25 + 1/2 ⋅ 20 ⋅ 8 = 105.
105 in. is the surface area of the square pyramid.
Stella bought 14 purses for $50. The next day she bought 2 more for a total of $38. What was the mean cost per purse?
Answer:
$48.5
Step-by-step explanation:
Given data
Number of purses= 14+2= 16
Cost of 14 purses= $50
Cost of 2 purses= $38
Let us use the weighted cost method
Mean cost = (14*50+ 2*38)/16
Mean cost = (700+ 76)/16
Mean cost = 776/16
Mean cost =$48.5

y=2x^2+12x+14 in vertex form
Answer:
y = 2(x + 3)² - 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms
= 2(x² + 6x) + 14
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9 ) + 14
= 2(x + 3)² - 18 + 14
= 2(x + 3)² - 4 ← in vertex form

1)A System of equations is shown below . What is the solution to the system of equations? 5x+2y=-15 2x-2y=-6
Answer:
x= -3 and y= 0
Step-by-step explanation:
5x+2y=-15
2x-2y=-6
7x =-21
x= -3
Putting value of x in equation 1
5(-3) +2y=-15
-15+2y= -15
2y= 0
y= 0
This can be solved with the help of matrices
In matrix form the above equations can be written in the form
[tex]\left[\begin{array}{ccc}5&2\\2&-2\/\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]
Let
[tex]\left[\begin{array}{ccc}5&2\\2&-2\/\end{array}\right][/tex] = A [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] = X and [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]= B
Then AX= B
or X= A⁻¹ B
where A⁻¹= adj A/ ║A║ where mod A≠ 0
adj A= [tex]\left[\begin{array}{ccc}-2&-2\\-2&5\/\end{array}\right][/tex]
║A║= ( 5*-2- 2*2)= -10-4= -14≠0
X= A⁻¹ B
[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] =- 1/14 [tex]\left[\begin{array}{ccc}-2&-2\\-2&5\/\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] =- 1/14 [tex]\left[\begin{array}{ccc}-2*-15&+ -2*-6\\-2*-15&+ 5*-6\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] =- 1/14 [tex]\left[\begin{array}{ccc} 30&+12\\30&+-30\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] =- 1/14 [tex]\left[\begin{array}{ccc}42\\0\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}-42/14\\0/-14\\\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}-3\\0\\\end{array}\right][/tex]

Leah walks to soccer practice on Saturday. She leaves her home and walks 600 meters north. Leah then turns east and continues on to the soccer field. The soccer field is 1000 meters from her home. How far east did Leah walk?
Answer:
800m
Step-by-step explanation:
this would be solved using Pythagoras theorem
we are to find the base
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
600² + b² = 100²
b² = 10000 - 3600
b² = 6400
take the square root of both sides
b = 800m
