Answer:

-5<x<9

Step-by-step explanation:

Within a triangle, the greater an angle, the greater the length of opposite side. So, since we know that 42° gives an opposite side of 23, and (3x+15)° gives an opposite side of 21, (3x+15) must be less than 42:

3x+15<42

3x<27

x<9

We also know that the angle (3x+15)° cannot equal zero or less than zero. So find x when 3x+15=0, and note that our value for x must be greater than this:

3x+15=0

3x=-15

x=-5

so, -5<x

Put both parts together to get: -5<x<9

Answer: [tex]5:00\ PM[/tex]

Step-by-step explanation:

Given

Truck A speed is [tex]v_a=60\ kmph[/tex]

Truck B speed is [tex]v_b=80\ kmph[/tex]

Truck A leaves 2 hours before truck B

Distance traveled in the 2 hour

[tex]\Rightarrow 60\times 2=120\ km[/tex]

Suppose Truck B will catch truck A after t hours

[tex]\therefore 120+60t=80t[/tex]

[tex]\Rightarrow 120=20t\\\Rightarrow t=6\ hr[/tex]

Overtake time is [tex]9:00am +2+6=5:00\ PM[/tex]

Answer:

  $241,399.09

Step-by-step explanation:

The value is increasing exponentially with a growth factor of 1.023, so it will be ...

  v(t) = 192,300×1.023^t

  v(10) = 192,300×1.023^10 ≈ 241,399.09

The value is predicted to be $241,399.09 in 10 years.

Answer:

The volume is 588 ft³

Step-by-step explanation:

[tex]v = a {}^{2} \frac{h}{3} = 14 {}^{2} \times \frac{9}{3} = 588[/tex]

Answer:

254.6 ft3 F

Step-by-step explanation:

To find the volume of the pyramid, first calculate the area of the base.

As the pyramid is the regular triangular pyramid, the base is an equilateral triangle.

To find the area of the equilateral triangle, calculate the length of the height.

Since the triangle is equilateral, each angle in the triangle equals 60°.

The height forms a 30°- 60°- 90° triangle. One leg of this triangle is equal to half of the side of the large triangle, or 7 ft. The other leg of the triangle is equal to 73‾√ ft by the 30°- 60°- 90° Triangle Theorem.

Therefore, the length of the height of the triangle is 73‾√ ft.

To find the area of the base of the pyramid, B, use the formula for the area of a triangle, B=12bh.

Substitute 14 for b and 73‾√ for h.

B=12⋅14⋅73‾√

Simplify.

B=493‾√ ft2

To find the volume of the pyramid, use the formula for the volume of a pyramid, V=13Bh.

Substitute 493‾√ for B and 9 for h.

V=13⋅493‾√⋅9

Simplify.

V=1473‾√

Use a calculator to approximate.

V≈254.6 ft3

Therefore, the volume of the regular triangular pyramid is about 254.6 ft3.

Answer:

7/100

Step-by-step explanation:

two decimal places so 100

Step-by-step explanation:

0.75(0.25x+8)-(0.5x+2)=0.375(4-x)-0.25x

0.1875x+6-0.5x-2=1.5-0.375x-0.25x

0.1875x-0.5x+0.375x+0.25x=1.5-6+2

0.3125x=-2.5

x=-2.5/0.3125

x= -8

Answer:

x= 20,1 degrees

Step-by-step explanation:

The sum of the inner angles of a triangle is 180 degrees

So it must be

3x-11+6x-10+x = 180

added up the terms with x

10x -11-10 = 180

added up the terms without x

10x - 21 = 180

added up (21) in the two members of the equation

10x-21+21 = 180+21

10x = 201

divide the two members by 10

x = 20,1 degrees

Answer:

-8, -1.5, 1/2, 1/4, 1/2, 1, 2.5, 3

Step-by-step explanation:

Answer:

-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2 (if is not 11/2 but 1  and 1/2) the answer is : -8, -1.5 , -1/2 , 1/4 , 1/2, 1 , 2.5, 3

Step-by-step explanation:

First of all we have to express the decimal numbers with a fraction

2.5 = 25/10 = 5/2

-1.5 = -15/10 = -3/2

now we have to express al numbers with a fraction with the same denominator. In this case the value that help us the most is 4

-1/2 = -2/4

5/2 = 10/4

-8 = -32/4

1/4 = 1/4

11/2 = 22/4

-3/2 = -6/4

3 = 12/4

now we have to check only the numerators for discover the order of the numbers. So from the least to the greatest we have:

-32/4 ; -6/4 ; -2/4 ; 1/4 ; 10/4 ; 12/4 ; 22/4

the final step is rewrite the original numbers in this order

-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2

Answer:

about 27 degrees

Step-by-step explanation:

all you do is 10 minus the negative 17 which two negative equal a positive so its then 10 +17 which equals 27

Answer:

25ft

Step-by-step explanation:

You take the bigger length of the two triangles and divide by the the smaller length of the smaller triangle. This is what the equation would look like:

30/6=5

Then you multiply 5 to the height of the smaller triangle and you got the height for the bigger triangle:

5 x 5=25
