Step-by-step explanation:
is calculating his expenses from his work trip to San Francisco. Below is the expense log he kept while traveling.
Expense Amount of Expense
Airfare $379.00 round trip minus $15.00 movie on plane
Hotel $154.00 per night × 3 nights
Dinner $65.00 plus $13.00 tip
Car Mileage $0.55 per mile × 63 miles
Keion will submit all of the expenses to his company for reimbursement except for the movie on the plane. How much will he be reimbursed for?
A
$784.65
B
$923.65
C
$925.65
D
$938.65
Answer:
D
Step-by-step explanation:
379.00 - 15.00 + 154.00 x 3 + 65.00 + 13.00 = 904
0.55 x 63 = 34.65
34.65 + 904 = 938.65
Answer:
Your answer is D
Step-by-step explanation:
because 379-15+154x3+65+13+0.55x63=938.65
Solve for x: 2(2a+3)-6=5a+2
Answer:
a=-2
We move all terms to the left:
2(2a+3)-6-(5a+2)=0
We multiply parentheses
4a-(5a+2)+6-6=0
We get rid of parentheses
4a-5a-2+6-6=0
We add all the numbers together, and all the variables
-1a-2=0
We move all terms containing a to the left, all other terms to the right
-a=2
a=2/-1
a=-2
Step-by-step explanation:
We move all terms to the left:
2(2a+3)-6-(5a+2)=0
We multiply parentheses
4a-(5a+2)+6-6=0
We get rid of parentheses
4a-5a-2+6-6=0
We add all the numbers together, and all the variables
-1a-2=0
We move all terms containing a to the left, all other terms to the right
-a=2
a=2/-1
a=-2
Please like and give me Brainliest!
Answer:
a = -2
Step-by-step explanation:
2(2a+3)-6=5a+2
distrubute the 2
4a + 6 - 6 = 5a + 2
combine like terms
4a = 5a + 2
-5a -5a
-a = 2
a = -2

An asteroid hit the earth and created a huge round crater. Scientists measured the distance around the crater as 26 miles. What is the area of the crater?
Answer:
53.8 mi^2
Step-by-step explanation:
First we need to determine the radius of the crater. The circumfence formula is C = 2(pi)r, and here C = 26 miles. Thus,
26 mi = 2(pi)r, so that
26 mi
r = ------------ = 4.13 miles
2pi
Then the area of the crater is A = (pi)r^2, or:
A = 3.14(4.13 mi)^2 = 53.8 mi^2

A 256- gallon barrel of radioactive Urikium is spilled at a factory. The entire area is evacuated. Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is to toxic for any clean-up efforts, so residents will just have to wait for the Urikium to evaporate. Fortunately, Urikium has a half-life of only three hours. That means that half of the Urikium will evaporate every three hours
Answer:
21 hours
Step-by-step explanation:
Since 2^8 = 256, that means it will take 7 half-lives to become two gallons
7 half-lives * 3 hours = 21 hours
256, 128, 64, 32, 16, 8, 4, 2
Answer:
Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is too toxic for any clean-up efforts. She residents will
Step-by-step explanation:
To solve half-life problems, you use the equations:
f(t) = T0 (1/2)^(t/t1/2). where T0 is the initial mass and T1/2 is the half-life.
So we get f(20)= 5 = T0•(1/2) ^ 20/11
T0 = 17.63 mg
For the second part of the question, we plug 0.5 mg into the equation:
0.5 = 17.63 • (1/2)^ t/11
t = 56.5 days

please help first one correct gets barlyest
Answer:
[tex] 10 \: { \: m}^{2} [/tex]
Step-by-step explanation:
area of the shaded region = Area of triangle formed in rectangle with base (10 - 6 = 4) 4m and height 2 m + Area of triangle formed in square with base 2 m and height 6 m
[tex] = \frac{1}{2} \times 4 \times 2 +\frac{1}{2} \times 2\times 6 \\ \\ = 4+6 \\ \\ = 10 \: { \: m}^{2} [/tex]
Answer:
shaded region = 10 m squared
Step-by-step explanation:
Area square = 6x6 = 36 Area reatangle 4x2 = 8
both areas = 44
Now lets subtract some white parts to obtain the shaded parts
1/2 of 4x6 = 12
1/2 of 6x6 = 18
1/2 of 4x2 =4
12+18+4= 34
44-34 = 10

Answer:
r = 3.7 cm
Step-by-step explanation:
19.02 = 1/2π(2radius) + diameter
expanding:
19.02 = 1/2(3.14)(2r) + 2r
19.02 = 3.14r + 2r = 5.14r
r = 19.02/5.14 = 3.7 cm

Answer:
The answer is 6.
Step-by-step explanation:
All you need to do is turn 33 and 44 into a fraction ([tex]\frac{33}{44}[/tex]). Then you need to simplify it and it's simplest form is [tex]\frac{3}{4}[/tex]. then you up the fraction to [tex]\frac{6}{8}[/tex] and that's your answer.
What is the value of BD
Well, by the segment addition postulate, 3x + 5 + 5x - 7 = BD, so BD = 8x - 2.
Because you didn't include the instructions in the picture, I can't be sure if this is a rhombus or a rectangle, but if it is either, then 3x + 5 = 5x - 7, and x = 6
If this is true, then BD = 48 - 2 = 46, but only if the shape is either a rhombus or rectangle (or both would make it a square).
Please help with the first one. Also could you tell me if the other one is correct? And if not could you correct it please.

When buying a candy bar, there is a 20% chance that it will also include a coupon for a second candy bar. A student wants to determine the probability that, if she buys 7 candy bars, more than 2 will include a coupon. To do this, she uses a random number table to pick 7 numbers from 1 to 5. She lets 1 represent a candy bar with a coupon and numbers 2 through 5 represent a candy bar without a coupon.. She repeats this for a total of 16 trials. The results are shown in the table.
