Kenny had a total of 140 minutes to read, do homework, and play video games. he spent x minutes reading. he spent 2(x + 5) minutes doing homework and he spent 25 minutes playing video games. How many minutes did Kenny spent reading?

Answer:

135...................

Answer:

40

Step-by-step explanation:

He can do 8 problems in 5 minutes. 25 minutes is 5 times more than 5. 8 times 5 is 40

Answer:

40 problems

Step-by-step explanation:

8 divided by 5 equals 1.6 meaning in one minute there are 1.6 problems answered, and so 1.6*25= 40. Meaning that there are after 25 minutes 40 problems will be solved.

The probability that this project will be completed within 130 days is 0.8413.

Expected duration (ED) = (Optimistic + 4 x Most Likely + Pessimistic) ÷ 6.

Optimistic = 41

Most Likely = 50

Pessimistic = 59ED = (41 + 4 × 50 + 59) ÷ 6 = 50

Duration = 50

Optimistic = 54

Most Likely = 60

Pessimistic = 66ED = (54 + 4 × 60 + 66) ÷ 6 = 60

Duration = 60

Optimistic = 58

Most Likely = 70

Pessimistic = 82ED = (58 + 4 × 70 + 82) ÷ 6 = 70

Duration = 70

Optimistic = 32

Most Likely = 41

Pessimistic = 44ED = (32 + 4 × 41 + 44) ÷ 6 = 41

Duration = 41

Total Project Duration = 50 + 60 + 70 + 41 = 221

Expected time for completing project = 221 days

The standard deviation of the critical path is obtained by using the following formula:

σ = P - O/6

Where σ represents the standard deviation of the critical path, P represents the pessimistic time, and O represents the optimistic time.

σ = 66 - 54/6 = 2.

Then, the probability that this project will be completed within 130 days:

z = (130 - 221) / 2 = -45.5P(z < -45.5) = 0 (due to negative value)

P(z < -4.5) = 0 (from normal distribution table)

Thus, the probability that this project will be completed within 130 days is 0.8413.

11. Slope of the line is 7/10.

12. Slope of the line is \(-\frac{1}{3}\)

Step-by-step explanation:

11. Given points are:

(-6, 1) and (4, 8)

Slope of a line is given by the formula;

m = \(\frac{y_2-y_1}{x_2-x_1}\)

m = \(\frac{8-1}{4-(-6)}\)

m = \(\frac{7}{4+6}\)

m = \(\frac{7}{10}\)

Slope of the line is 7/10.

12. Given points are:

(2, -3) and (5, -4)

Slope of the equation is;

m = \(\frac{-4-(-3)}{5-2}\)

m = \(\frac{-4+3}{3}\)

m = \(\frac{-1}{3}\)

Hence,

Slope of the line is \(-\frac{1}{3}\).

HG, CD, and PN are the segments which are the images of segment AB

The only transformations that we have are Reflections, rotations and/or translations.

You should notice that none of these transformations are dilations/contractions.

This means that the length of the segment will remain constant.

Then the possible images of AB after the sequence of transformations, are the segments that have the same length as AB.

The length of AB is 4 units.

The segments with the same length are:

HG, CD and PN

So any of those could be the image of AB after the transformations.

Caroline leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches Mattie’s house.

The shortest distance between Caroline's and Mattie's house is 10 blocks.

If we assume this as a right angle triangle then height (BA) is 6 blocks long and base (BC) is 8 blocks

long.

Then, the shortest distance between Caroline's and Mattie's house will be the hypotenuse (AC) of this

triangle.

So, by applying Pythagoras theorem:

\((AC)^{2} = (BA)^{2} = (BC)^{2} = (6)^{2}+(8)^{2}\) = 36+64 = 100

Thus, AC = \(\sqrt{100}\) = 10 blocks.

Hence, the shortest distance we can take from Caroline's house to reach Mattie's house is 10 blocks.

To implement the function f(w1,w2,w3) = Σ m(0, 2, 4, 5, 7) using a 3 to 8 binary decoder and an OR gate, we can connect the input lines w1, w2, and w3 to the A, B, and C inputs of the decoder, respectively.

To implement the given function f(w1,w2,w3) = Σ m(0, 2, 4, 5, 7), we first need to convert it into a truth table as follows:

w1    w2    w3    f

0       0       0     0

0       0        1      1

0        1       0      0

0        1       1       1

1        0       0      0

1        0       1       0

1        1        0       1

1        1       1         1

Here, the binary values of w1, w2, and w3 are listed in the first three columns, and the corresponding value of f is listed in the fourth column. The expression Σ m(0, 2, 4, 5, 7) indicates that the function f should be equal to 1 for the minterms 0, 2, 4, 5, and 7.

We can use a 3 to 8 binary decoder to implement this function as follows:

The input lines of the decoder are w1, w2, and w3.

The outputs of the decoder are eight lines labeled Y0, Y1, Y2, Y3, Y4, Y5, Y6, and Y7, each corresponding to one of the possible input combinations of w1, w2, and w3.

The output line corresponding to each minterm that evaluates to 1 is connected to the input of an OR gate.

The output of the OR gate is the output of the function f.

Specifically, we can connect the input lines w1, w2, and w3 to the decoder as follows:

w1 is connected to the A input of the decoder.

w2 is connected to the B input of the decoder.

w3 is connected to the C input of the decoder.

The eight outputs of the decoder are connected to the inputs of an OR gate as follows:

Y0 is not connected to the OR gate since it corresponds to the input combination 000, which is not a minterm in the function.

Y1 is connected to one input of the OR gate since it corresponds to the input combination 001, which is a minterm in the function.

Y2 is not connected to the OR gate since it corresponds to the input combination 010, which is not a minterm in the function.

Y3 is connected to one input of the OR gate since it corresponds to the input combination 011, which is a minterm in the function.

Y4 is connected to one input of the OR gate since it corresponds to the input combination 100, which is a minterm in the function.

Y5 is connected to one input of the OR gate since it corresponds to the input combination 101, which is a minterm in the function.

Y6 is not connected to the OR gate since it corresponds to the input combination 110, which is not a minterm in the function.

Y7 is connected to one input of the OR gate since it corresponds to the input combination 111, which is a minterm in the function.

The other input of the OR gate is connected to ground (or logic 0).

The yield to maturity on a simple loan for $1,500 that requires a repayment of $7,500 in five years' time is 37.14%.

Yield to maturity (YTM) is the total return anticipated on a bond or other fixed-interest security if the security is held until it matures. Yield to maturity is considered a long-term bond yield, but is expressed as an annual rate. In this problem, the present value (PV) of the simple loan is $1,500, the future value (FV) is $7,500, the time to maturity is five years, and the interest rate is the yield to maturity (YTM).

Now we will calculate the yield to maturity (YTM) using the formula for the future value of a lump sum:

FV = PV(1 + YTM)n,

where,

FV is the future value,

PV is the present value,

YTM is the yield to maturity, and

n is the number of periods.

Plugging in the given values, we get:

$7,500 = $1,500(1 + YTM)5

Simplifying this equation, we get:

5 = (1 + YTM)5/1,500

Multiplying both sides by 1,500 and taking the fifth root, we get:

1 + YTM = (5/1,500)1/5

Adding -1 to both sides, we get:

YTM = (5/1,500)1/5 - 1

Calculating this value, we get:

YTM = 0.3714 or 37.14%

Therefore, the yield to maturity on a simple loan for $1,500 that requires a repayment of $7,500 in five years' time is 37.14%.

The approximate volume of the larger candle is 244 cubic centimeters.

To find the volume of the larger candle, we need to compare the side lengths of the smaller and larger candles. Let's denote the side length of the smaller candle as "s."

According to the information given, the side length of the larger candle is five-fourths (5/4) as long as the side length of the smaller candle. Therefore, the side length of the larger candle can be calculated as (5/4) * s.

The volume of a square pyramid is given by the formula V = (1/3) * s^2 * h, where s is the side length of the base and h is the height.

Since both the smaller and larger candles have the same shape, their volume ratios will be equal to the ratios of their side lengths cubed.

Let's substitute the values into the volume ratio equation:

(125 / V_larger) = (s_larger / s_smaller)^3

Given that V_smaller = 125 cubic centimeters, we can rewrite the equation as:

(125 / V_larger) = ((5/4) * s_smaller / s_smaller)^3

Simplifying the equation:

(125 / V_larger) = (5/4)^3

Calculating (5/4)^3:

(125 / V_larger) = (125 / 64)

Cross-multiplying the equation:

125 * 64 = V_larger * 125

Solving for V_larger:

V_larger = (125 * 64) / 125

Approximating the value:

V_larger ≈ 64 cubic centimeters

The approximate volume of the larger candle is 244 cubic centimeters, rounded to the nearest cubic centimeter

Answer:

\(\boxed {\tt 4.2 \ miles}\)

Step-by-step explanation:

Let's set up a proportion using the following setup:

\(\frac{miles}{minutes}= \frac{miles}{minutes}\)

We know Abdul can run 6 miles in 50 minutes.

\(\frac{6 \ miles}{50 \ minutes}= \frac{miles}{minutes}\)

We don't know how many miles he can run in 35 minutes. Therefore, she can run x miles in 35 minutes.

\(\frac{6 \ miles}{50 \ minutes}= \frac{x \ miles}{35 \ minutes}\)

\(\frac{6 }{50 }= \frac{x }{35 }\)

We want to solve for x ( miles ran in 35 minutes). We must isolate x on one side of the proportion. x is being divided by 35 and the inverse of division is multiplication. Multiply both sides of the proportion by 35.

\(35*\frac{6 }{50 }= \frac{x }{35 }*35\)

\(35*\frac{6 }{50 }= x\)

\(35*0.12=x\)

\(4.2=x\)

x=4.2 miles

He can run 4.2 miles in 35 minutes.

The terminal point \( P(x, y) \) on the unit circle determined by \( t = -5\pi \) is \((-1, 0)\).

To find the terminal point \( P(x, y) \) on the unit circle determined by the value of \( t = -5\pi \), we can use the parametric equations of the unit circle:

\[ x = \cos(t) \]

\[ y = \sin(t) \]

Substituting \( t = -5\pi \) into the equations, we get:

\[ x = \cos(-5\pi) \]

\[ y = \sin(-5\pi) \]

We know that \(\cos(-5\pi) = \cos(\pi)\) and \(\sin(-5\pi) = \sin(\pi)\). Using the properties of cosine and sine functions, we have:

\[ x = \cos(\pi) = -1 \]

\[ y = \sin(\pi) = 0 \]

Therefore, the terminal point \( P(x, y) \) on the unit circle determined by \( t = -5\pi \) is \((-1, 0)\).
