Answer:

Cost of five blouses = $145

Step-by-step explanation:

Let

x = cost of blouse

y = cost of skirt

15x + 2y = 505 (1)

5x + 2y = 215 (2)

Subtract (2) from (1) to eliminate y

15x - 5x = 505 - 215

10x = 290

x = 290/10

x = 29

Substitute x = 29 into (2)

5x + 2y = 215 (2)

5(29) + 2y = 215

145 + 2y = 215

2y = 215 - 145

2y = 70

y = 70/2

y = 35

x = cost of blouse = $29

y = cost of skirt = $35

How much do 5 such blouses cost?

cost of a blouse = $29

Cost of five blouses = $29 × 5

= $145

Cost of five blouses = $145

If w = 10 units, x= 5 units, and y= 6 units, what is the surface area of the figure?
qwelly [4]

Answer:

  456.2 units²

Step-by-step explanation:

The area of the square base is ...

  base area = w² = (10 units)² = 100 units²

The lateral area is 4 times the area of one rectangular face:

  lateral area = 4wx = 4(10 units)(5 units) = 200 units²

The area of one triangular face is half the product of its base length (w) and its slant height (h). The latter is found using the Pythagorean theorem:

  h² = y² +(w/2)² = (6 units)² +((10 units)/2)² = 61 units²

  h = √61 units

So, the area of 4 triangles is ...

  area of triangular faces = 4(1/2)wh = 2(10 units)(√61 units) ≈ 156.2 units²

__

Now we have the areas of the parts, so we can add them together to get the total surface area:

  surface area = base area + lateral area + area of triangular faces

  = 100 units² + 200 units² + 156.2 units²

  surface area = 456.2 units²

Point B(6, -3) is translated using the rule (x -5 y + 9) what is the y coordinate of B'
Andrej [43]

This rule shows how we transition the x-coordinate and y-coordinate when finding B'.


In this rule, it shows us what to add/subtract from the x-value and y-value in the coordinate. We can see that it wants us to subtract 5 from the x-value (based on the "x - 5") and that it wants us to add 9 to the y-value (based on the "y + 9"). Based on this information, we can find B':

\textrm{B}'(6 - 5, -3 + 9)

\boxed{\textrm{B}\,'(1, 6)}


The "y-coordinate" of B' is 6.
