Step-by-step explanation:

11. YX = 4.5

RQ corresponds to ZY. If RQ is 4 and ZY is 3, then ΔQRP was dilated by 0.75 to form ΔYZX. (3/4 = 0.75). Using this knowledge, we can find the length of YX by multiplying 6 by 0.75. (YX corresponds to QP). 6 × 0.75 = 4.5.

12. 55°

All of a triangle's angles must add up to 180°. ∠Q is 88°. ∠Z is 37°. ∠Z is congruent to ∠R because corresponding angles in similar triangles are congruent. So, 88° + 37° = 125°. We need to get to 180°, so 180° - 125° = 55°.

13. 4.2

BC corresponds to DF. We need to find the scale factor, so divide 2.7 by 3.6. That equals 0.75. AC corresponds to EF. EF is 5.6, so multiply 5.6 by 0.75. That equals 4.2.

I hope this helps :))

Answer:

Step-by-step explanation:

the zeroes of a function basically mean when y = 0, so basically the x-intercept(s)

in this case, the zeroes are 3 and 6

How many square feet of outdoor carpet will

jonny [76]

Answer: $30\ ft^2$

Step-by-step explanation:

The missing figure is attached.

For this exercise you can divide the given figure into three rectangles.

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght and "w" is the width.

Knowing this, you can calculate the area of each rectangle.

Then:

Area of the Rectangle A

You can identify that:

$l_A=4\ ft\\w_A=2\ ft$

Then, its area is:

$A_A=(4\ ft)(2\ ft)\\\\A_A=8\ ft^2$

Area of the Rectangle B

Observe that:

$l_B=4\ ft+2\ ft=6\ ft\\w_B=2\ ft$

Then, its area is:

$A_B=(6\ ft)(2\ ft)\\\\A_B=12\ ft^2$

Area of the Rectangle C

You can identify that:

$l_C=5\ ft\\w_C=2\ ft$

Then, its area is:

$A_C=(5\ ft)(2\ ft)\\\\A_C=10\ ft^2$

Add the area of the rectangles in order to find the total area. This is:

$Total=8\ ft^2+12\ ft^2+10\ ft^2\\\\Total=30\ ft^2$

Therefore, you will need $30\ ft^2$ of outdoor carpet for that hole.

Tresset [83]

Answer:

2.49

Step-by-step explanation:

Given X= 58

N = 175.

P = 25% = 0.25.

$P' = \frac{X}{N} = \frac{58}{175} = 0.3314\\Z = \frac{P'-P}{\sqrt{\frac{pq}{N} } }$

Now plugging the values we get

$= \frac{0.3314-0.25}{\sqrt{\frac{0.25\times0.75}{175} } }$

=2.49
