Bob went for a drive in his new car. He drove for 127.5 miles at a speed of 51 miles per hour. For how many hours did he drive?

The probability that a car is red is 1/3

The given parameters are

P(Car has two doors, given that it is red) = 0.6

P(car has two doors and is red) = 0.2

The probability that a car is red is

P(Red) = P(car has two doors and is red)/P(Car has two doors, given that it is red)

This gives

p(Red) = 0.2/0.6

Evaluate

p(Red) = 1/3

Hence, the probability that a car is red is 1/3

Answer:

Step-by-step explanation: 2x+12x = 14x

14x=70

70/14 = 5

x = 5

Answer: x=29

Step-by-step explanation:

12=70-2x

12=-2x+70

Subtract 70 from both sides: 12-70=-2+70-70

Step-by-step explanation:

this a complementary angle. This means that both sides add up to 90 degrees. 90-54=36

Answer:

36°

Step-by-step explanation:

These angles are complimentary, meaning they add to 90°. You know this by the little square marking.

The first term of the geometric sequence is a(1) = 7.

The nth term of a geometric sequence is given by:

a(n) = a(1) . rⁿ⁻¹

Where:

a(1) = the first term

r = ratio

Parameter given in the problem:

a(5) = 112

Plug n = 5 into the formula

a(1) . r⁵⁻¹ = 112

a(1) . r⁴ = 112    ....... (1)

a(7) = 448

Plug n = 7 into the formula

a(7) = a(1) . r⁶

448 = a(1) . r⁶  ..... (2)

Divide (2) by (1)

448 : 112 = r⁶ : r⁴

4 = r²

Since  r² = 4, then r⁴ = ( r² )² = 4² = 16.

Substitute r⁴ = 16 into equation (1):

a(1) . 16 = 112

a(1) = 112/16 = 7

The slower stone will take 3.33 seconds if the faster stone takes 10s to return to the ground.

It is defined as the rate of change in linear velocity with respect to time. It is also known as linear acceleration.

From the motion equation:

s = ut + at²/2

From the data given:

s = 0

0 = 3u(10) - 9.8(10)²/2

After solving:

u = 16.33 m/s

To calculate for time:

s = ut + at²/2

s = 0

u = 16.33

0 = 16.33t + 9.8t²/2

t = 3.33 seconds

Thus, the slower stone will take 3.33 seconds if the faster stone takes 10s to return to the ground.

Answer:

x = 3

Step-by-step explanation:

2(4 + 3x) + 6 = 32 ( subtract 6 from both sides )

2(4 + 3x) = 26 ( divide both sides by 2 )

4 + 3x = 13 ( subtract 4 from both sides )

3x = 9 ( divide both sides by 3 )

x = 3

As a check

substitute x = 3 into the left side of the equation and if value obtained is equal to the right side (32) then it is a solution to the equation.

2(4 + 3(3)) + 6

= 2(4 + 9) + 6

= 2(13) + 6

∠6 = 43°

If two angles sum to 90 degrees, they are said to be complementary angles. In other terms, a right angle is created when two complementary angles are combined (90 degrees). Angles 1 and 2 are complementary if their total of angles equals 90 degrees (i.e., ∠1 + ∠2 = 90°), and as a result, they are referred to as each other's complements.

Now as per the question the given angle is

∠8 = 47°

It is also given that ∠6 and ∠8 form are complementary angles. Therefore it means that the sum of both the angles will be 90°

∠6 + 47° = 90°

Now subtracting 47 from both sides we will get :

∠6 = 90 - 47 = 43°

Therefore, ∠6 = 43°

∠AHF is the exterior angle to the triangle GHI, so m∠AHF = 116°.

What is exterior angle?

When one side of a triangle is stretched, an external angle is generated. An external angle of a triangle is a non-straight angle (one that is not merely an extension of a side) that is outside the triangle but next to an interior angle.

From figure, m∠CIH = 105° (given)

so, m∠GIH = (180° - m∠CIH) = (180° - 105°) = 75° (complementary angles)

And m∠BGD = 41°

So, m∠IGH = M∠BGD = 41° (vertically opposite angles)

Now, m∠AHF = m∠GIH + m∠IGH (exterior angle)

                       = 75° + 41°

                       = 116°
