The area of a square floor on a scale drawing is 100 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?
Answer:
900 ft
Step-by-step explanation:
I if 1 centimeter equals 3 ft and the dimensions are 10 cm by 10 cm then the real dimensions are 30 ft by 30 ft and that is 900 ft.

The price of a notebook has dropped to $3.45 today. Yesterday's price was $3.95. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
10%
Step-by-step explanation:
($3.95 - $3.45)/($3.95) × 100%
= ($0.50)/($3.95) × 100%
= 50/3.95 %
= 5000/395 %
= 1000/79 %
= 12,65 % → Round to the nearest tenth
≈ 10 %

A triangle is shown
What is x?
What is y?
What is z?
Answer:
x = 44
y = 136
z = 136
Step-by-step explanation:
The angles of a triangle have to add up to 180°
54 + 82 + x = 180
136 + x = 180
x = 44
We know that y and z are vertical angles, so they have the same measurements.
Also, x and the other angle across from it are also vertical angles.
88 + 2n = 360
2n = 272
n = 136
Therefore,
x = 44
y = 136
z = 136
Deion is making sandwiches for a picnic. He uses 2 slices of cheese to make each sandwich,
and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!
Answer:
12 sandwiches
Step-by-step explanation:
We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:
24 / 2 = 12
Therefore, Deion can make 12 sandwiches before he runs out of cheese.
Hope this helps :)

can you add fractions with unlike denominators? if so what do you have to do.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

John has a part time job.
He is paid £6.80 per hour.
This week he worked for 9 1/2 hours.
Work out John's total pay for this week.
Step-by-step explanation:
Given,
John get paid for working per hour = £6.80
he worked this week = 9 1/2 hr can be written as 19/2 hr.
so, total amount he will get paid for working 19/2 hr
= 19/2 × 6.80
= 19 × 3.40 = 64.60 or 64.6
therefore, John's total.pay of this week is £64.6.

What is the equation, in slope-intercept form, of the line that passes through
the point (7, 2) and is parallel to y= -2x+1?
Find the slope of the parallel line
(7, 2) and is parallel to y= -2x+1?
When two lines are parallel, they have the same slope.
⇒ if the slope of the given line is = - 2
then the slope of the parallel line (m) = - 2
Determine the equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 2 = - 2 (x - 7)
We can therefore write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:
since y - 2 = - 2 (x - 7)
∴ y = - 2 x + 16PLEASE HELP ME ASAP.
Step-by-step explanation:
anything whole or complete is designated as 100%.
what is x% of that whole ?
well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.
100×f = x
f = x/100
whole × f = x% of the whole
so, when we are looking for 5%, what did that mean ?
it means that x = 5, and f = 5/100.
therefore, 5% of $13 is
13 × 5/100 = 65/100 = 0.65
so,
basic cost = $13
tax rate = 5%
tax amount = $0.65
and
basic cost = $13
tax amount = $0.65
total cost = 13 + 0.65 = $13.65
as 5/100 = 0.05
we have seen that the tax amount is simply $13×0.05
and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total
total cost = $13×(1+0.05) = $13×1.05 = $13.65
so, the decimal factor we can use directly without going through all the detail above is : 1.05

-35 + ( -31 ) + ( -39 )
Answer:-105
Step-by-step explanation:
Answer:
Ok so, let's break it down
Step-by-step explanation:
-35+(-31)
Let's ignore the parenthesis and the - symbol
35+31
That would equal 66, so now we add back the - symbol which will make it -66
So we already have -66, so now we have -66+(-39)
We do the same thing we did with -35+(-31)
So we have 66+39
That makes -105
So your answer is -105

There are 130 people in a sport centre.
61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?
The probability that this person does not make use of the facility is 7/130
How to solve for the probability61+68+60 - 25-28-19 + 6
= 123
The total number of person in the sport center is given as 130
We have 130 - 123 = 7
This means that there are a total of 7 persons that do not make use of this facility.
Hence the probability of a person not using the facility is 7/130

Please use the Pythagorean Theorem and show me how you do it-- thanks.
Answer: 2.5 feet
Step-by-step explanation:
A 30-60-90 triangle is a special right triangle in which the sides all have a fixed relationship with each other. We only need to know one side to calculate the other two.
Make the side opposite the 30° angle x, then
The side opposite the 60° angle is x*√3The side opposite the 90° angle is 2xThe side opposite the right angle is 5ft, therefore:
2x = 5
x = 2.5ft, the side opposite the 30° angle
Then x*√3 is the third side:
(2.5)*(1.442) = 3.605 feet

How do you write 7 1 \12 as a whole number
Answer: 7
Step-by-step explanation:
Write as a decimal
7 1/2 would be written as ~7.0833
Rounding a decimal to the nearest whole number
If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.
If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
Since 0 is in the tenth’s place we round down to 7.
