Answer:

Step-by-step explanation:

A) identical triangles PSR and PSQ

B) in the given triangle PQR angle P is 90 degrees and PS is perpendicular on QR. so the angle PSR and angle PSQ is 90 degrees also angles RPS , SPQ are 45 degrees . hence when two angles of a triangle are 90 and 45 degrees. the third is also 45 degrees. when the three angles of two triangles are equal they are said to be similar

C) the triangle PSR is a isosceles triangle therfore the two sides of the two oposite equal angles must be equal. if RS=4 then SP=4 as well the sides opposite to 45 degrees angles. the third side can be found by using the formula

c²=a²+b²

c²=4²+4²=16+16=32

c=√32=√16*2=4√2

Step-by-step explanation:

$h = \frac{3}{4} 4.8 \ = \\ = 3 \times 1.2 = 3.6$

$area = \frac{3.6 \times 4.8}{2} = \\ = 3.6 \times 2.4 = \\ = 8.64$

Help please and that you 13-16

denis-greek [22]

Answer:

See explanation.

Step-by-step explanation:

13. (4*5)/2 = 10

14. 5*7=35 7-3=4 8-5=3 (4*3)/2 = 6 35+6 = 41

15. 3*4 = 12

16. (4*4)/2 = 8 8*4=32 4*2=8 16*8=128 128-32 = 96

Let me know if you want me to better explain how I solved any of these.

Question 37 (1 point)

o-na [289]

Answer:

The probability is:

$P =\frac{1}{16}$

Step-by-step explanation:

Keep in mind that the probability of getting a head is always the same for each

$p = 0.5$

Therefore the probability of not having a head is:

$q = 1-p = 0.5\\q = 0.5$

So if we throw the coin 4 times the probability P of not getting any head is:

$P = q * q * q * q\\\\P = q ^ 4\\\\P = 0.5 ^ 4\\\\$

$P =\frac{1}{16}$

Solve for x: (x − 2) = 4x. (1 point)

Georgia [21]

Steps:

(x-2)=4x

Pretend that there is a one in front of x-2

1(x-2)=4x

Multiply the bracket by 1

x-2=4x

Move x to the other side .Whenever you move a number or letter the sign changes.

x-x-2=4x-x

-2=3x

Divide by 3 for -2 and 3

-2/3=3/3 x

x=-2/3

Check answer by using substitution method

(-2/3-2)=4(-2/3)

(-2/3-6/3)=-8/3

-8/3=-8/3

Answer is -2/3
