Answer:
105 for 3 hours
Step-by-step explanation:
First we have to find that how much he is charged for 1 hour.
140 : 4 = 35 per hour
Then we have to find how much he is charged for 3 hours by multiplying with 3.
3 x 35 = 105 per 3 hours
Answer:
£105
Step-by-step explanation:
let y represent the unknown amount
£150 = 4 hrs
y = 3 hrs
we then cross multiply
£150 x 3 hrs = y x 4 hrs
450= 4y
divide both sides by 4
450/4 = 4y/4
105 = y

Answer:
11) A=84.7m²
12) A=75.2km²
13) A=28.05ft²
14) A=48yd²
Step-by-step Explanation:
11) A = 1/2(bh)
A = 1/2(14×12.1)
A = 1/2(169.4)
A = 84.7m²
12) A = 1/2(bh)
A = 1/2(16×9.4)
A = 1/2(150.4)
A = 75.2km²
13) A = 1/2(bh)
A = 1/2(5.1×11)
A = 1/2(56.1)
A= 28.05ft²
14) A = 1/2(bh)
A = 1/2(16x6)
A = 1/2(96)
A = 48yd²
Answer:
11) A=84.7m²
12) A=75.2km²
13) A=28.05ft²
14) A=48yd²

Two trains, train a and train , weigh a total of 466 tons. Train A is heavier than train b. The difference of there weights is 326 tons. What is the weight of each train
Answer: A = 396 tons
B = 70 tons
Step-by-step explanation:
From the question,
Weight of A + Weight of B = 466
Weight of A - Weight of B = 326
A + B = 466 ......... i
A - B = 326 ..........ii
Subtract equation ii from I
2B = 140
B = 140/2
B = 70 tons
A = 466 - 70
A = 396 tons

PLEASE HELP ASAP!! DUE TODAY
Answer:
Step-by-step explanation:
when 1/2 inch equals 4 feet the room is 2.25 inches, then
2 1/4 = 8/4 + 1/4 = 9/4
9/4 inches is the scale distance of the room
each 1/2 inch is 4 feet so divide 9/4 by 1/2 then multiply that by 4 to find the distance of the room
9/4 ÷ 1/2 = 9/4
9/4 * 2/1 = 18/4
18/4 = 9/2
9/2 * 4 feet = 9/2 * 4/1
9/2 * 4/1 = 36/2
36/2=18
the room is 18 feet across
then if the scale is 2/3 of an inch is 4 feet , then
2/3 * 9/4 = 18/12
18/12 = 3 inches is the scale size of Quinto's room

Using Pascal triangle, write down the binomial expansion of

simplifying all the terms.
Answer:
1 + 8y + 28y² + 56y³ + 70[tex]y^{4}[/tex] + 56[tex]y^{5}[/tex] + 28[tex]y^{6}[/tex] + 8[tex]y^{7}[/tex] + [tex]y^{8}[/tex]
Step-by-step explanation:
For the expansion of [tex](1+y)^{8}[/tex]
Using the row of Pascal's triangle for n = 8 , that is the coefficients are
1 8 28 56 70 56 28 8 1
Decreasing powers of 1 from [tex]1^{8}[/tex] to [tex]1^{0}[/tex]
Increasing powers of y from [tex]y^{0}[/tex] to [tex]y^{8}[/tex]
Then
[tex](1+y)^{8}[/tex]
= 1 . [tex]1^{8}[/tex].[tex]y^{0}[/tex] + 8. [tex]1^{7}[/tex].[tex]y^{1}[/tex] + 28. [tex]1^{6}[/tex].y² + 56. [tex]1^{5}[/tex].y³ + 70.

You collect a random sample of size n from a population and calculate a 98% confidence interval. Which of the following strategies produces a new confidence interval with a decreased margin of error?
A: Use a 99% confidence level.
B: Use a 95% confidence level.
C: Decrease the sample size.
D: Use the same confidence level, but compute the interval n times. Approximately 2% of these intervals will be larger.
E: Nothing can guarantee that you will obtain a larger margin of error. You can only say that the chance of obtaining a larger interval is 0.02.
Answer:
B: Use a 95% confidence level.
Step-by-step explanation:
In the case when the random sample size from a population is collected and it determined the 98% confidence interval so that decrease the margin of error is to use a 95% confidence interval as it is needed to have a less critical value
So according to the given options, the option B is correct

Explain when you should reverse the inequality symbol when solving an equality.
Answer:
To do this, subtract 6 from both sides. − 3_x_ + 6 − 6 > 12 − 6. −3_x_ > 6. Now divide both sides of the inequality by −3. Since you're dividing by a negative number, you need to flip the inequality sign.

Joon is buying lotion for her mom's birthday. The lotion was originally priced at $18 but is now on sale for 20% off. How much will Joon pay for the lotion?
Answer:
Discount price= $14.4
Step-by-step explanation:
Giving the following information:
Original selling price= $18
Discount rate= 20% = 0.2
To calculate the discount price, we need to use the following formula:
Discount price= selling price * (1 - discount rate)
Discount price= 18 * (1 - 0.2)
Discount price= $14.4

How to find a side of a square when area is given?
Answer:
length =√area use this formula
The side length of square can be found by taking the square root of Area.
What are Squares?Square are closed polygons which consist of four sides and four angles.
Each angle is 90 degree.
All the sides are of equal length.
So, by the definition of square, we know that the side lengths of square are equal.
The formula to calculate the area of the square is,
Area = a², where a is the length of one side of the square.
Let Area be given, let it be equal to A.
Then,
a² = A
Taking square root on both sides,
a = √A
Hence the side length is found by taking the square root of Area.

Approximately how much fuel can fit into a tanker truck with a radius of 4 feet and a height of 32 feet?
-18+x=-x+12
This one ??
Answer:
X = 15
Step-by-step explanation:
Let's solve your equation step-by-step.
−18+x=−x+12
Step 1: Simplify both sides of the equation.
x−18=−x+12
Step 2: Add x to both sides.
x−18+x=−x+12+x
2x−18=12
Step 3: Add 18 to both sides.
2x−18+18=12+18
2x=30
Step 4: Divide both sides by 2.
2x/2 30/2 = 15
