Find the length of side x in simplest radical form with a rational denominator.

Step-by-step explanation:

here's your solution

=> x^2 + 15x + 50

=> By using middle term split

=> x^2 + 10x + 5x + 50

=> taking common from each

=> x(x + 10) + 5(x + 10)

=> (x + 5) (x + 10

Answer:

your answer is Option D. ∧ACD≈ ∧BCD because of SAS

Step-by-step explanation:

hope it helps...

The relationships proved to be ΔACD ≈ ΔBCD, because of SAS (Side Angle Side).

SAS" is when we know two sides and the angle between them. If the two sides of a triangle are equal to the two sides of another triangle, and the angle formed by these sides in the two triangles are equal, then these two triangles are congruent. The SAS Criterion stands for the 'Side-Angle-Side' triangle congruence theorem.

To prove the SAS :-

In ΔACD and ΔBCD

AD=BD (Given)
D=D(Common 90° angle)

CD=CD (Common)

Therefore, ΔACD ≅ ΔBCD, because of SAS (Side Angle Side) rule.

Answer:

25% markup

Step-by-step explanation:

they bought 200 shirts for 1600, which is 8$ per shirt

if they sell then at 10$ they get 2 dollars profit.

if you do 2/8 you get 25%

Also 1/4 of 8$ is 2$ and that is what your profit is.

Answer:

25%

Step-by-step explanation:

Cost of one short:

1600 : 200 = $8

8 + 8(x/100)= 10

800 + 8x= 1000

8x = 200

x = 25 %

Step-by-step explanation:

The function f(x)=x2 is not one-to-one because f(2) = f(-2). Its graph is a parabola, and many horizontal lines cut the parabola twice. The function f(x)=x 3, on the other hand, IS one-to-one. If two real numbers have the same cube, they are equal.

Answer:

AB = sqrt 74 = 8.602

Step-by-step explanation:

simple:

a^2+b^2=c^2

5^2+7^2=74

ab=sqrt 74

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(8−3)2+(2−9)2(8-3)2+(2-9)2

= √52+(−7)252+(-7)2

= √25+4925+49

= √7474 = 8.6023

Distance between points (3, 9) and (8, 2) is 8.6023

Step-by-step explanation:

Solution :

It is given that the distance between the two lights is 30 feet.

The angle of elevation of the upper light from the boat, ∠ ABP = 32 degree

The angle of elevation of the lower light from the boat, ∠ ABQ = 14 degree

∴ ∠ PBQ = ∠ ABP - ∠ ABQ

              = 32 - 14

              = 18 degree

In triangle PAB

∠ PAB = 180 - (90 + 32)

           = 58 degree

Similarly in triangle AQB

∠ AQB = 180 - (90 + 14)

           = 76 degree

Now considering triangle PBQ and applying the sine theorem,

[tex]$\frac{PQ}{\sin 18}=\frac{BQ}{\sin 58}$[/tex]

we know PQ = 30 feet

∴ [tex]$BQ =\frac{\sin 58}{\sin 18} \times 30$[/tex]

        = 82.33 feet

Again taking the right triangle ABQ and applying sine theorem,

[tex]$\frac{BQ}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

[tex]$\frac{82.33}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

∴ [tex]$AB = 82.33 \times \sin 76$[/tex]

         = 79.88 ft

         = 80 feet

Answer:

a) 6 ways

b) 6 ways

Step-by-step explanation:

a) for all of the letters

for the first letter, we have 3 options

for the second, we have 2 options

for the third, we have 1 option

So the number of options will be;

3 * 2 * 1 = 6

b) for the first, we have 3 options, for the second, we have 2 options

so the number of options will be 3 * 2 = 6 options

Answer: $81.03

Step-by-step explanation:

The interest is compounded annually which means that the future value formula applies:

Future value = Amount * ( 1 + rate) ^ number of years

Amount = $70

Rate = 5%

Number of years = 3 years

In 3 years, Ernesto will have:

= 70 * ( 1 + 5%)³

= $81.03
