Helppp please and thank you !

a) 5 m

b) 8 yd

Step-by-step explanation:

a) Take the ratios of the legs of the triangles. Since they are similar triangles, those ratios are equal.

d/(4 m) = (10m)/(8 m)

Solving for d,

d =(10/8)(4 m) = 5 m

b) m/(10 yd) = (12 yd)/(10 yd + 5 yd) = 12/15 = 4/5

Solving for m,

m = (4/5)(10 yd)

= 8 yd

Answer:

d = 5m

m = 6yd

Step-by-step explanation:

Question 1.)

We know that segment GF is half of CD, therefore EF would be half of CE.

=> CE / 2 = EF or d

=> 10 / 2 = EF or d

=> 5 = EF or d

Question 2.)

We know that segment DE is half of EF, so segment EG would be half of DH;

=> DH / 2 = EG or m

=> 12 / 2 = EG or m

=> 6 = EG or m

Hope this helps!

Answer:

(12, 0)

Step-by-step explanation:

The centre of the circle is at (4, 0) and the radius = √64 = 8.

So one point on the circle is at ((4 + 8), 0) = (12,0).

Answer:

100 pi cm^2

or approximately 314 cm^2

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

The radius is 5

SA = 4 *pi * 5^2

SA = 4*pi(25

SA = 100 pi cm^2

If pi is 3.14

SA = 100 *3.14 = 314 cm^2

2) MT, GT

3) ∠G

4) not enough information...because we are given two congruent sides but an angle that is not included.

5) SAS because two sides are congruent (including the one they share) and an included angle.

6) SSS because three sides are congruent (including the one they share).

Answer:

Independent.

Step-by-step explanation:

Independent events:

Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

[tex]P(A \cap B) = P(A)P(B)[/tex]

Thus, P(A and B)=P(A)•P(B) is used when two events are independent.

Answer: b= - -log10(7)+3/2

Step-by-step explanation: log 10 (7) -2b-9=-6 : b= - -log10(7)+3/2 (Decimal : b = -1.07745...)

so these are the steps how I got it I did log 10 (7)-2b-9=-6 subtract log 10 (7) -9 from both sides log 10 (7)-2b-9-(log10(7)-9)=-6-(log 10 (7) -9)

Simplify -2b= -log10(7)+3

Divide both sides by -2  -2b/2= - log 10(7)/-2+ 3/-2 if you simplify it should give you b= - -log10(7)+3/2 that should be your answer but i'm not sure those I think that's how you do it let me know if you got it right bye!

Answer:

h = 28 inches

Step-by-step explanation:

Let the base of the triangle is b.

the height of the triangle is 4 inches less than four times its  base.

h = 4b-4

The area of the triangle is 112 inch².

The formula for the area of a triangle is given by :

[tex]A=\dfrac{1}{2}bh\\\\112=\dfrac{1}{2}\times b\times (4b-4)[/tex]

It is a quadratic equation, whose solution is as follows :

b = -7 and b = 8 inches

Height, h = 4(8)-4

= 32-4

= 28 inches

Hence, the height of the triangle is 28inches.

Answer:

p = -5

Step-by-step explanation:

7(p + 1) = 2(3p + 1)

Distribute on both sides.

7p + 7 = 6p + 2

Subtract 6p from both sides.

p + 7 = 2

Subtract 7 from both sides.

p = -5

Answer:

p = -5

Step-by-step explanation:

7(p + 1) = 2(3p + 1)

Distribute

7p +7 = 6p +2

Subtract 6p from each side

7p +7 -6p = 6p+2-6p

p+7 = 2

Subtract 7 from each side p+7-7 =2-7

p=-5

Answer:

2k + 4

Step-by-step explanation:

David,

Start by performing the indicated multiplication:

5(k+2)-3(k+2) becomes 5k + 10 - 3k - 6.

Next, combine like terms:  5k - 3k + 10 - 6 becomes 2k + 4

This 2k + 4 is the desired simpler result.

Answer:

B

Step-by-step explanation:

Step-by-step explanation:

length of each rectangle= 9 1/14=127/14

breadth of each rectangle=5=4 1/2= 9/2

so perimeter of 1 rectangle= 2(l+r)

=2(127/14+ 9/2)

=2(127+63)/14

=2×190/14

=190/7

=27.14 feet

so total length of fencing= 4×27.14

=108.57 feet
