Answer: A. $907.10

B. $628.236

Step-by-step explanation:

For the first 40 hours, Ms.Donaldson will earn: = 40 × $18.80 = $752.0

We are informed that Ms.Donaldson worked 45.5 hours, this means that she worked an extra 5.5 hours. The amount paid for the extra hour will be:

= 5.5 × 1.5 × 18.8

= $155.10

The amount she earned will be:

= $752.0 + $155.10

= $907.10

B. A health incurrence payment of $34.55 was deducted from Ms.Donaldson's earnings for the week. Therefore, the amount she will have after the deduction will be:

= $907.10 - $34.55

= $872.55

After the incurrence deduction, payroll taxes equal to 28% of the balance were deducted. What was the amount that Ms.Donaldson received afterwards?

This will be:

= $872.55 - (28% × $872.55)

= $872.55 - (0.28 × $872.55)

= $872.55 - $244.314

= $628.236

BlackZzzverrR [31]

Answer:

8/125

Step-by-step explanation:

Given

red balls : 6

yellow balls : 7

green balls : 2

total balls = 6 + 7 + 2 = 15

P(red ball) = 6 / 15 = 2/5

P(3 consecutive red balls with replacement),

= (2/5) x (2/5) x (2/5)

= 8/125

The points (-2,-10) and (-1, v) fall on a line with a slope of 8. What is the value of v?
Nutka1998 [239]
I think the answer is -2

Following the rule of “rise over run”, the fraction form of the gradient it 8 over 1 (8/1)
This means you move up 8 units, and move across 1 unit.
The final coordinate is (-1, -2)
V = -2

Hope this helps!

URGENT, HELP ASAP

Answer:

The sales will surpass 37 million in about 2013.

Step-by-step explanation:

The answer can be found via solving an exponential inequality as follows:

f(x) = 20(1.05)^x\\20(1.05)^x> 37\\1.05^x> \frac{37}{20}\\x\log 1.05>\log\frac{37}{20}=\log 37 - \log 20\\x>(\log 37 - \log 20)/\log 1.05=12.6\\x>12.6 \,\,\mbox{years}

Any number of years larger than 12.6 will satisfy the inequality, i.e., after more than 12.6 years from year 2000, the annual sales will surpass 37 million. The answer to the exact question will then be: in about 2013 the sales will surpass 37 million.

Find the volume of the composite figure below
Marina86 [1]

Answer:

1386 in³

Step-by-step explanation:

Volume of the composite cone = volume of a hemisphere + volume of a cone

=>Find the volume of cone

Volume of cone = ⅓πr²h

π = 3.142

r = 7 in

h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]

h = √(225 - 49)

h = √176 ≈ 13 in

Volume of cone = ⅓*3.142*7²*13

= ⅓*2001.454 ≈ 667 in³

=>Find volume of hemisphere.

Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³

π = 3.142

r = 7 in

Volume = ⅔*3.142*7³ ≈ 719 in³

<em>Volume of composite figure = 667+719 = 1386 in³</em>

Answer:

The s represents the y-intercept of the graph.

The 100t in the equation means the initial velocity of the rockey is 100

Step-by-step explanation:

According to the text and graph.

The s reprecets the yintexept of the graph

h(t)=5+100t-16t²

h(t)=100-32t

k(0)=100

in terms of the rocket The 100t in the equation means the initial velocity of the rockey is 100
