Answer:

d, e, g, and h.

Step-by-step explanation:

Adjacent angles sit next to each other, and don't overlap.

Answer:

Below in bold.

Step-by-step explanation:

We have a right triangle here with the hypotenuse = 2 and the legs are 1 and √3.

If tan A > 0 then the opposite side to < A  in the triangle is greater than the adjacent so the leg opposite angle A is √3 and the adjacent side = 1.

So cos A = adj/hyp = 1/2.

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

[tex]Total=h+(h-2)[/tex]

[tex]Total=2h-2[/tex]

It is given that the total number of visitors is 80. So,

[tex]2h-2=80[/tex]

[tex]2h=80+2[/tex]

[tex]2h=82[/tex]

Divide both sides by 2.

[tex]h=\dfrac{82}{2}[/tex]

[tex]h=41[/tex]

Therefore, the correct option is D.

Answer: Hi, there your answer is x=5

Step 1: Add 4 to both sides.

3x−4+4=11+4

3x=15

Step 2: Divide both sides by 3.

3x/3=15/3

x=5

Answer:

s(t) = -4.9t² + 39.2t

Step-by-step explanation:

Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²

Given

g = -4.9m/s²

v0 = 39.2m/s

s0 = 0m (the initial height)

On substituting into the formula;

s(t) = gt² + v0t + s0

s(t) = -4.9t² + 39.2t + 0

s(t) = -4.9t² + 39.2t

This gives the equation that models the height

Answer:

1.2 times or 20%

Step-by-step explanation:

Given the function ; f(x) = 830(1.2)^x

This is an exponential function ;

Recall the general form of an exponential function ; f(x) = ab^x ;

Where a = Initial value ; b = growth rate

Hence, b = 1.2

Also, b = 1 + r

1.2 = 1 + r

r = 1.2 - 1

r = 0.2

r = 0.2 * 100% = 20%

Answer:

$2250

Step-by-step explanation:

selling the ring at 100% of $1500 would equal 1500 and yield no profit

therefore, you must sell the ring at 150% (where 100% covers the cost and the additional 50% provides the profit) of 1500

1.5 x 1500 = 2250

250

250 is in-between 200 nd 300

Answer:

Step-by-step explanation:

This is one of those questions that  has no answer. The first one is not a triangle. 3 and 6 = 9. Two of the legs have to longer than the third. 9 is not greater than 10.

So there is no answer. However leave a note of there is a mistake in what you wrote and I'll come back.

The other two are right (the middle one) and the last one is acute.

Answer:

y = 2x - 3

Step-by-step explanation:

Take any two points from the graph

(0,-3)   & (2 ,1)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

         [tex]= \frac{1-[-3]}{2-0}\\\\= \frac{1+3}{2}\\\\= \frac{4}{2}\\\\= 2[/tex]

m = 2

[tex]y - y_{1}=m(x -x_{1})\\\\y - [-3] = 2(x - 0)\\\\y + 3 = 2x\\\\y = 2x - 3[/tex]

Answer:

Answer:

Your answer would be the third one

Step-by-step explanation:

Triangle 1 - 73, 45

Triangle 2 - 47, 30

Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

Option (4) is correct.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

As per the given data:

We are given two angles for each pair of triangles, and we have to find out which of the pair of triangles are similar.

For any two triangles to be similar, it must have 2 angles which are having the same measure.

For, Triangle 1: 55°, 45° and Triangle 2: 55°, 80°

Only one angle is same, hence not similar.

Triangle 1: 103°, 32° and Triangle 2: 103°, 25°

Only one angle is same, hence not similar.

Triangle 1: 73°, 47° and Triangle 2: 47°, 30°

Only one angle is same, hence not similar.

Triangle 1: 105°, 23° and Triangle 2: 52°, 105

By using angle sum property in Triangle 1 the remaining angles is:

= 180 - (105 + 23) = 52°

By using angle sum property in Triangle 2 the remaining angles is:

= 180 - (52 + 105) = 23°

2 angles are same, hence similar.

Triangle 1: 99, 41° and Triangle 2: 40°, 99°

Only one angle is same, hence not similar.

Hence, Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

Answer:

g(5) = -19

Step-by-step explanation:

Substitute 5 for x in the equation

Plug in 5 for the x's and get g(x)=-3(5)-4 and then -15-4 which is -19 so g(x)=-19

Answer:

Given 3 sides are 4,4,7 cm. We know sum of 2 sides of triangle are greater than 3rd side. But given sides 4+4 doesn't equal 7. It's not possible to construct a triangle with the given lengths (4,4,7).

Step-by-step explanation:

U can only make a triangle with the same 3 length.
