Answer: 2 : 50 pm

Step-by-step explanation:

If Jan took a break at 3:05 pm and she had been jumping rope for 15 minutes before that, to find the time she started jumping rope, subtract 15 from the current time:

= 3:05 - 15

= 2:50 pm

Jan started jumping rope at 2 : 50 pm

Answer:

(a) PR = 55.2 cm

(b) RT = 19.7 cm

(c) <RPT = [tex]20.8^{o}[/tex]

Step-by-step explanation:

(a) to determine the value of PR, apply the Pythagoras theorem to PQR.

PQ = 45, and SP = QR = 32. So that;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]/PR/^{2}[/tex] = [tex]45^{2}[/tex] + [tex]32^{2}[/tex]

          = 2025 + 1024

          = 3049

PR = [tex]\sqrt{3049}[/tex]

     = 55.218

PR = 55.2 cm

(b) To determine RT, apply the appropriate trigonometric function to QRT.

Let RT be represented by x, so that;

Sin [tex]38^{o}[/tex] = [tex]\frac{x}{32}[/tex]

x = 32 * Sin [tex]38^{o}[/tex]

  = 32 * 0.6157

x = 19.7024

RT = 19.7 cm

(c) To determine <RPT, let the angle be represented by θ.

Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

        = [tex]\frac{RT}{PR}[/tex]

Sin θ = [tex]\frac{19.7024}{55.218}[/tex]

         = 0.3568

θ = [tex]Sin^{-1}[/tex] 0.35568

  = [tex]20.84^{o}[/tex]

Thus, <RPT = [tex]20.8^{o}[/tex]

Answer: [tex]1.4\times 10^{-6}[/tex]

Step-by-step explanation:

Given

The wavelength of light is 0.0000014 inches

Here, seven digits are followed by a decimal point

To convert it to scientific notation, convert it into a fraction i.e.

[tex]=0.0000014=\dfrac{14}{10,000,000}[/tex]

In the denominator, there are 7 zeroes

[tex]\therefore 0.0000014=\dfrac{14}{10^7}\\\\\Rightarrow 0.0000014=14\times 10^{-7}\\\\\Rightarrow 0.0000014=1.4\times 10^{-6}[/tex]

The probability Matt will choose pepperoni pizza and Ashley will choose a salad is 1/4.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

There is a 75% chance Matt will choose pepperoni pizza

= 75/ 100

= 3/4

and, Ashley chooses a salad which had a chance = 1/3.

As, the events are independent then we know that if two events A and B are independent evets then

P(a B)= P(A) . P(B).

so, the probability is

= 1/3 x 3/4

= 1/4

Answer:

(1.5,6)(15,33) slope=2

Step-by-step explanation:

Answer:

y-2x=3; A(1.5, 6) B(15,33) Slope = 2

Step-by-step explanation:

First thing, you add 2x on both sides and get y=2x+3. Since the equation y=mx+b states that m is the slope, the slope is 2.

2nd step is finding the missing coordinate for a. You plug in 6 as the y in the equation y=2x+3, and then get 2x+3=6. Now it is a simple algrebraic equation and you get x=3/2 or 1.5.

The final step is to solve for B. Using the equation y=2x+3, and substituting in x as 15, you get y=30+3 which equals 33.

I hope this gave you an in depth explanation on solving these problems!

Answer/Step-by-step explanation:

To complete the table, substitute the value of n into c = 10n + 19 to get its corresponding value.

Thus:

When n = 6,

c = 10(6) + 19

c = 60 + 19

c = 79

When n = 7

c = 10(7) + 19

c = 70 + 19

c = 89

When n = 9,

c = 10(9) + 19

c = 90 + 19

c = 109

Answer:

[tex]V_d=976.9ft[/tex]

Step-by-step explanation:

From the question we are told that:

Height of cylinder h_1=114 feet

Diameter d=1

Length of triangular prism [tex]l_2=34ft[/tex]

Width of triangular prism  [tex]w_2=34ft[/tex]

Height of triangular prism [tex]h_2=1 ft[/tex]

Generally the equation for Volume of the cylinder is mathematically given by

 [tex]V_c=\pir^2h[/tex]

Where

 [tex]r=d/2\\r=0.5[/tex]

Therefore

 [tex]V_c-=\pi*0.5*114[/tex]

(5x)÷5 = (150)÷5

x = 30

Answer:

x = 30.

3x/10+x/5=15

Multiply through by 10:

3x + 2x = 150

Answer:

5/12

Step-by-step explanation:

because $1 = 100 cents

ratio = 50 cents / ($1.2 x 100) = 5/12

just convert to the same currency

The ratio of 50 cents to $1.20 is [tex]\frac{5}{12}[/tex]

'A ratio can be defined as the comparison between two numbers of the same unit to check how bigger is one number than the other one.

According to the given problem,

Amount in cents = 50 cents

                            = 0.5 dollars

Amount in dollars = $1.2

Ratio = [tex]\frac{0.5}{1.2}[/tex]

        = [tex]\frac{5}{12}[/tex]

Hence, we can conclude, the ratio is [tex]\frac{5}{12}[/tex].
