Answer:

Step-by-step explanation:

To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.

Answer:

Area of A is 30

Step-by-step explanation:

total area = 280

amount of area given= 60+60+50+50

                                   =220

area left = 280-220

              =60

Area of 1 A= 60/2

                 =30

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:

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.

Answer:

d, e, g, and h.

Step-by-step explanation:

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

Answer:

20%/100×73.28=14.65

Step-by-step explanation:

to answer this you have to find out what 20% of 73.28 is by dividing 20% by 100 then multiplying by 73.28

Answer:

Step-by-step explanation:

If cost is directly proportional to speed, then the equation for this is

£ = ks, where k is the constant of proportionality. We need to solve for this first.

400 = k4 so

100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:

£ = (100)(6) so

£ = 600

Answer:

x = 70

Step-by-step explanation:

The two angles are same side interior angles and same side interior angles add to 180

45+ (2x-5) = 180

Combine like terms

2x +40 = 180

Subtract 40 from each side

2x+40-40 =180-40

2x =140

Divide by 2

2x/2 = 140/2

x = 70

Answer:

x=70

Answer:

C

Step-by-step explanation:

Answer:

option c is correct

Step-by-step explanation:

y = 2x +5

5 = 2*0 +5

5 = 0 +5

5=5

y = 2x +5

9 = 2*2 + 5

=9 = 4 +5

9=9

y = 2x +5

13 = 2*4 +5

13 = 8 + 5

13 = 13

therefore option c is correct because it satisfies all the elements of x and y of the given function when we substitute the values.

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

Answer:

Scale Factor = 1/2

x = 3

Hope this helps!

Answer:

Step-by-step explanation:

Scale factor = 1/2

x = 6/2 = 3

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

Step-by-step explanation:

Half the numbers on the die are even so you have a 1/2 probability of getting an even number. There is also. 1/2 probability of getting heads on a coin flip.

To find the probability of both happening, multiply the probability of each together:

1/2 x 1/2 = 1/4

The probability of getting an even number and heads is 1/4

D, solved it graphically

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:

Angles F and H are congruent.

Step-by-step explanation:

Answer:

Angles F and H are congruent.

Step-by-step explanation:

Answer:

24 squared ft.

Step-by-step explanation:

Area of a triangle is 1/2(b*h)

b=8 ft, c=6 ft

Therefore, area

= 1/2(8*6)

= 1/2(48)

= 24 square ft
