Answer:
60
Step-by-step explanation:
if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20
Answer:
The Answer is 30 questions in total.
Step-by-step explanation:
1. The first thing you would want to do is to break down this question.
For every 6 questions, this is 20% of the test done.
2. You now would want to divide 100% (the full amount on the test) by 20%.
100%/20% = 5
3. Now, multiply both to get your answer.
6·5= 30
20%x5= 100%.
Therefore, the total amount of questions on the test is 30 questions.

A triangle has two sides of length 17 and 4. What is the smallest possible whole-number
length for the third side?
Answer:
14
Step-by-step explanation:
because the sum of the 2 smaller side have to add up to greater than the larger side
x+4 > 17
x > 13
14 is the next biggest whole number

Answer:
11.25 or 11 1/4
Step-by-step explanation:
seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole
so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-
now we need the dimensions of each one-
rectangle one
l=5 w=2
rectangle two
l=5 w=1/4
now let us set up the equation and solve-
a=lw
rectangle one
a=5*2=10
rectangle two
a=5*1/4=1.25
and the last step is to add together the areas of both rectangles
10+1.25=11.25
and since you need your answer as a mixed number the answer is 11 1/4
(to do this you just put 11.25 over 100 and then simplify)
good luck :)
i hope this helps

What’s the measure of an arc with radius 45 inches and central angle of 135°?
Answer:
106.028752
Step-by-step explanation:
First, find the circumference which is 2 pi r.
2pi(45), 90pi, 282.743339
135 out of 360 degrees is 135/360 or 3/8
and 3/8 out of 282.743339 is 106.028752
The distance from Detroit, MI to Paris, France is approximately 3930 mi. Flying from Detroit to Paris takes 8 hr with the jet stream. The return flight takes 8.3 hr since the plane is flying against the jet stream.
a. The speed of the plane in still air, rounded to the nearest whole number, is
b. The speed of the jet stream, rounded to the nearest whole number, is
Answer:
a. 482
b. 9.0
Step-by-step explanation:
The speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph
How does air stream affects speed of flight?Flight speed in air stream = Flight speed in still air + effect of air stream
If the flight is going opposit, then:
Flight speed in air stream = Flight speed in still air - speed of air streamIf the flight is going along with flight, then:
Flight speed in air stream = Flight speed in still air + speed of air streamFor this case, we're specified that:
Distance from Detroid to Paris is approx 3930 milesTime it takes by flight along the air stream = 8 hoursTime it takes by flight against the air stream = 8.3 hoursSpeed of flight along the stream is:
[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8} = 491.25 \: \rm mph[/tex]
Speed of flight against the stream is:
[tex]S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8.3} \approx 473.49 \: \rm mph[/tex]
Let the speed of air stream be y, and that of the flight in still air be x miles per hour, then we get:
Along air stream:
[tex]x + y =491.25\\[/tex] (in miles per hour)
and Against the stream:
[tex]x - y =473.49\\[/tex] (in miles per hour)
Adding both the equations side by side, we get:
[tex]2x + y - y = 491.25 + 473.49\\\\x = \dfrac{964.74}{2} =482.37 \: \rm mph[/tex]
Using this value, we get the value of y as:
[tex]x + y =491.25\\y = 491.25 - x = 491.25 - 482.37 = 8.88 \: \rm mph[/tex]
Rounding to the nearest whole numbers, we get:
x = 482 mph, and y = 9 mph
Thus, the speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph

Brandon is rolling two six-sided dice. What is the probability that one die lands on an even number and the other die lands on an odd number?
Answer:
50-50 on both because there 3 even and 3 odd numbers
Answer:
50% chance of either or 1/2
Step-by-step explanation:
50% of either
Look a die has 12 sides
6 numbers are odd and the other 6 even
If you randomly roll a die you will have 6/12 chances of landing on a even number and a 6/12 chance of landing on a odd number
now 6/12 can be simplified to 1/2 which is 50%

What is the equation of the line that passes through the point (−0.5,8) and has a slope of −5?
Answer:
Slope=-1.8, X=-0.5, y=1.9
Equation is y^2-y^1=m(x^2-x^1).
Y-1.9=-1.8(X-(-0.5))
Y-1.9=-1.8x+0.90
Add 1.9 on both sides.
Y= -1.8x+1.

Step-by-step explanation:
You decide that you want new carpeting in your bedroom that measures 12 feet 6 inches wide by 15 feet 9 inches long. The price of the carpet and the underlying pad is $3.49 per square foot. You decide to upgrade to the deluxe underlying pad that costs an additional $0.62 per square foot. The fee for installation is a flat fee of $180. What is the total cost, including sales tax of 6.7%, of the carpet, pad, and installation? Round your answer to the nearest cent. Write the equation that represents the total cost.
Answer:
The total cost of the new carpeting is $ 1,055.43.
Step-by-step explanation:
Since I decide that I want new carpeting in my bedroom that measures 12 feet 6 inches wide by 15 feet 9 inches long, and the price of the carpet and the underlying pad is $ 3.49 per square foot, and I decide to upgrade to the deluxe underlying pad that costs an additional $ 0.62 per square foot, and the fee for installation is a flat fee of $ 180, to determine what is the total cost, including sales tax of 6.7%, of the carpet, pad, and installation, the following calculations must be performed:
1 inch = 0.08333 feet
6 inches = 0.08333 x 6 = 0.5
9 inches = 0.08333 x 9 = 0.75
12.5 x 15.75 = Bedroom area
196,875 square feet = Bedroom area
((196.875 x (3.49 + 0.62)) + 180) x 1.067 = Total cost
((196,875 x 4.11) + 180) x 1,067 = Total cost
(809.15625 + 180) x 1.067 = Total cost
989.15625 x 1.067 = Total cost
1,055,429 = Total cost
Therefore, the total cost of the new carpeting is $ 1,055.43.

10-7=3 and this with numbers:
-7-8=-15 (both negative again)

Like this: 4+1=5 and -2+1=-1
7. 8(x+10)= 8*x+8*10= 8x +80
8. 8(1+6p)= 8*1+8*6p= 8+48p
9.-5(-7+7n)= 35-35n ( when you * negative and positive numbers you get negative result and when you * negative and negative numbers you get positive result)
10.-(9m+7)= -9m-7 ( when you have - before () every number changes its sign).
