A ball is launched upward at 26 ft/sec from a platform that is 12 feet high. When will the ball hit the ground

Answers

Answer 1

Answer:

9.4 seconds or 1 second

Step-by-step explanation:

From;

h = ut ± 1/2gt^2

h = 12 feet

g = acceleration due to gravity = 10 m/s^2

u = 26 ft/sec

Since it is an upward motion g is negative

12 = 26t - 5t^2

Hence;

5t^2 - 26t + 12 = 0

Solving the quadratic equation

Considering that the time taken to go up is the same time taken to hit the ground again

t = 2(4.7) seconds or t = 2(0.5) seconds

t = 9.4 seconds or 1 second

it will rain on exactly zero of the five days they are there? Round your
answer to the nearest thousandth.

Answers

Answer: Probability is 0.00205 = 0.205%

Step-by-step explanation: P(rain) = 0.71, P(no rain) = 0.29.

P(no rain in 5 days)= 0.29·0.29·0.29·0.29·0.29= 0.00205

9 - 0.5x = 15
solve for x and show your work.

Answers

Answer:

Step-by-step explanation:

Answer:

x = - 12

Step-by-step explanation:

9 - 0.5x = 15

* isolate the variable using inverse operations *

step 1 subtract 9 from each side

9 - 9 cancels out

15 - 9 = 6

now we have -0.5x = 6

step 2 divide each side by -0.5

-0.5x / -0.5 = x

6 / -0.5 = - 12

we're left with x = - 12


Carl has a new job making $8.25 an hour. He worked 16.75 hours last week. He also
had deductions of 6.25% for Social Security and 1.45% for unemployment insurance.
What was Carl's net pay last week (the amount after deductions)?

Answers

Answer:

Step-by-step explanation:

Earnings = 16.75 hours × $8.25/hour = $138.1875

Deductions = 6.5% + 1.45% = 7.95%

net = 92.05% of $138.1875 ≈ $127.20

A European bond has a par value of 1000 Euros, a coupon rate of 4.5 percent and a yield to maturity of 3.2 percent. The bond has 19 years to maturity. Coupons are made annually. What is the value of the bond?

Answers

Answer:

Bond Price​= 1,182.96

Step-by-step explanation:

Giving the following information:

Par value= 1,000

Cuopon= 1,000*0.045= 45

YTM= 3.2%

Number of years (n)= 10

To calculate the price of the bond, we need to use the following formula:

Bond Price​= cupon*{[1 - (1+i)^-n] / i} + [face value/(1+i)^n]

Bond Price​= 45*{[1 - (1.032^-19)] / 0.032} + [1,000 / (1.032^19)]

Bond Price​= 633.31 + 549.65

Bond Price​= 1,182.96

I dont get this Rewrite the equation below so that it does not have fractions. 2-(3)/(4)x=(9)/(10) Do not use decimals in your answer.

Answers

Answer:

Suppose we have an equation like:

[tex]\frac{A}{C} = \frac{B}{D}[/tex]

If we want to remove the denominators, we should multiply both sides by each denominator.

First, let's multiply both sides by C.

[tex]\frac{A}{C}*C = \frac{B}{D}*C[/tex]

[tex]A = \frac{B}{D}*C[/tex]

Now let's multiply both sides by D.

[tex]A*D = \frac{B}{D}*C*D[/tex]

[tex]A*D = B*C[/tex]

So now we removed the denominators.

Now let's do this to our expression.

[tex]2 - \frac{3}{4*x} = \frac{9}{10}[/tex]

First, let's multiply both sides by 10

[tex](2 - \frac{3}{4*x})*10 = \frac{9}{10}*10[/tex]

[tex]20 + \frac{30}{4*x} = 9[/tex]

Now let's multiply both sides by 4*x

[tex](20 + \frac{30}{4*x})*4*x = 9*4*x[/tex]

[tex]20*4*x - 30 = 9*4*x[/tex]

[tex]80*x - 30 = 36*x[/tex]

Now we can solve this for x:

[tex]80*x - 36*x = 30[/tex]

[tex]44*x = 30[/tex]

[tex]x = \frac{30}{44} = 0.68[/tex]

Answers

Answer:

384

Step-by-step explanation:

8 x 6 = 48

48 x 2 = 96

12 x 10 = 120

6 x 12 = 72

8 x 12 = 96

96 + 120 + 72 +96 = 384

Answer:

Step-by-step explanation:

Remark

Surface area for this = Top +  bottom + left side + 2 triangles.

The hypotenuse of the triangle can be found by the Pythagorean Theorem.

a^2 + b^2 = c^2

a = 6

b = 8

c = ?

c^2 = 6^2 + 8^2

c^2 = 36 + 64

c^2 = 100

sqrt(c^2) = sqrt(100)

c = 10

Top

Top = Length * Width

Top = 12 * hypotenuse

Top = 12 * 10

Top       =                                         120

Left side = L*W

L = 12

W = 6

Area = 6 * 12

Area =                                               72            

                         

Two triangles

Two Triangles = 2* (1/2) * 6 * 8 =   48  

Base

W = 8

L = 12

Area = L*W

Area = 8 * 12                                   96

Total area = 96 + 48 + 72+120 = 336

JoAnn likes her job as a baby-sitter, but it pays only $3 per hour. She has been offered a job as a tutor that pays $6 per hour. Because of school, her parents only allow her to work a maximum of 15 hours per week. How many hours can JoAnn tutor and baby-sit and still make at least $66 per week? How much does she make?

Answers

I took a screen shot of the math

From the graph, solution of inequalities is (8, 7). Therefor, she worked as a baby-sitter for 8 hours and worked as a tutor for 7 hours.

Given that, JoAnn likes her job as a baby-sitter, but it pays only $3 per hour.

What are inequalities?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Total number of hours JoAnn worked is 15 hours

Let the number of hours she worked as a baby-sitter be x hours, the number of hours she worked as a tutor will be y hours.

Now, x+y<15

3x+6y>66

The intersection consists of the elements that are contained in all of the intervals.

x<15-y and x>22-2y

From the graph, solution of inequalities is (8, 7). Therefor, she worked as a baby-sitter for 8 hours and worked as a tutor for 7 hours.

Step-by-step explanation:

The given is a right triangle

which means one of the angle has a measure of 90

so if we add up all the angles

65 + 90 + x = 180 add like terms

155 +x = 180 subtract 155 from both sides
