What if the driver of the Ferrari 550 was cruising along and suddenly hit the brakes to stop because she saw a cat on the road? She skidded to a stop, and fortunately, missed the cat. When she got out of the car she measured the skid marks left by the car so that she knew that her braking distance was 31 ft. How fast was she going when she hit the brakes?

Answer:

Step-by-step explanation:

A = 180°-90°-50° = 40°

Use Law of Sines to find a:

a = b⋅sinA/sinB ≈ 20.1 units

Use Pythagorean Theorem to find c:

c = √(a² + b²) ≈ 31.3 units

:::::

sin(x) = 16/25

x = arcsin(16/25) ≈ 39.8°

Answer:

True

Step-by-step explanation:

Since a penny has head and tails, each has 1/2 chance to land on heads or tales, so 14*1/2=7, so true.

Answer:

D) Factors of the polynomial

Step-by-step explanation:

Example: If the polynomial 10x² represents the area of the rectangle, then

2x and 5x will be the dimensions of the rectangle. Thus they will be factors of the polynomial.

So, dimensions of the rectangle represents the factors of the polynomial.

Answer:

55-5x

Step-by-step explanation:

she does 5 hours each day

in x days, hours of service=5x

after x days the hours of service left are=55-5x

the linear equation representing the hours Johnny has left after x days is:

55-5x

Answer:

b=42 degrees

c= 138 degrees

Step-by-step explanation:

B and the 42 degrees shown are congruent angles so therefore both are 42 degrees

To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore

subtract 180 with 42 to get Angle C

180-42= 138

Answer:

b=42, c=138

Step-by-step explanation:

B has to equal 42 because b is opposite of the 42º

and since 42+2c+42 has to equal 360, we simplify the expression to get:

84+2c=360,

2c=276

c=138

Answer:

13 times

Step-by-step explanation:

There are a total of 270 minutes in 4 1/2 hours.

270 ÷ 20 = 13.5

Though we know that 13.5 would not work out.

So she would check on it 13 times.

After the 13th time there will be 10 minutes left to cook the turkey.

The total number of times Alana will check the turkey before it sis done is 13 times.

The rate at which Alana is checking the turkey can be described as the work rate or the rate at which she is doing work.

The total number of times at which Alana will check the turkey before it is done is calculated as follows;

[tex]n = \frac{T}{R}[/tex]

where;

T is the total time = 4 1/2 h = (4 x 60) + 30 min = 270 min

R is the rate = 20 min

[tex]n = \frac{270}{20} \\\\n = 13.5 \ times\\\\n \approx 13 \ times[/tex]

There is no half checking, thus, the total number of times Alana will check the turkey before it sis done is 13 times.

The answer is [tex]{\underline{\boxed{\sf{\purple{4}}}}}[/tex]

Step-by-step explanation:

Solution :

To solve the above equation we will follow the BODMAS rule.

It stands for :

[tex]\begin{gathered}\quad\begin{gathered} \small \begin{array}{l} \star \: \rm B= bracket \\\star \: \rm O= order \: of \: power \: \\\star \: \rm D= division \\\star \: \rm M= multiplication \\ \star \: \rm A= addition \\ \star \: \rm S=subtraction \end{array}\end{gathered}\end{gathered}[/tex]

Solving the question by bodmas rule :

[tex]\implies\tt{\dfrac{15 - 7 + 3(6 + 2)}{{2}^{3}}}[/tex]

[tex]\implies\tt{\dfrac{15 - 7 + 3(8)}{2 \times 2 \times 2}}[/tex]

[tex]\implies\tt{\dfrac{15 - 7 + 3 \times 8}{4\times 2}}[/tex]

[tex]\implies\tt{\dfrac{15 - 7 + 24}{8}}[/tex]

[tex]\implies\tt{\dfrac{39- 7}{8}}[/tex]

[tex]\implies\tt{\dfrac{32}{8}}[/tex]

[tex]\implies\tt{\cancel{\dfrac{32}{8}}}[/tex]

[tex]\implies\tt{\underline{\underline{\red{4}}}}[/tex]

Hence, the answer is 4.
