Answer:
134
Step-by-step explanation:
first, separate the floor into 3 different rectagles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9.5*7=66.5
rec 2: (10.5-4.5)*(14.5-5-7)=15
rec 3:5*10.5=52.5
Then:
66.5+52.5+15=134
b) If it costs £4 to buy 5 pens, how much will it cost to buy 8?
Answer:
10 because you need to find how much one pen would cost. So you decide 5 and 4. the result would be 1.25 then you multiple the result by 8. you get 10

In a college, there are 800 students in the first year, 950 students in the second year and 1000 students in the third year. If this data were graphed as a pie chart, what would be the size of the angle in the third year?
Answer: [tex]130.9^{\circ}[/tex]
Step-by-step explanation:
Given
The number of students in the first year is 800
The number of students in the second year is 950
The number of students in the third year is 1000
If this data is graphed on a pie chart, then the area percentage of area occupied by third years is
[tex]\Rightarrow \dfrac{1000}{1000+950+800}\times 100=36.36\%[/tex]
Now, the angle around the center of the circle is [tex]360^{\circ}[/tex]
[tex]\therefore \text{angle covered by third years=}0.3636\times 360^{\circ}\\\Rightarrow 130.896\approx 130.9^{\circ}[/tex]
what is 78.57 rounded to the nearest hundredth?
Answer:
79 would be rounded to the nearest hundredth
Answer:
78.57
Step-by-step explanation:
The number in the hundredths place is 7. 78.570
So then you look to the number to the right which is zero so you round down to 78.57
So, the answer is the same.
78.57

Answer:
D. She should find the average of 4.4 and 4.5
Explanation:
(4.4 + 4.5)/2 = 4.45
4.45² ≈ 19.80
4.45² is closer to 20 than 4.4² and 4.5²
next she will repeat the same process: (4.45 + 4.5)/2

a set contains the numbers 0,6,12, and 15 Two different numbers are selected randomly from this set. What is the probability that the sum is greater than 12? What is the probabilty the product is 72?
The probability that the sum is greater than 12 is [tex]\frac{2}{3}[/tex]. The probability the product is 72 is [tex]\frac{1}{6}[/tex].
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes
The outcomes that the sum is greater than 12
6 and 12, 6 and 15, 12 and 15, 0 and 15
So the probability that the sum is greater than 12 is
= [tex]\frac{4}{C^{2} _{4} }[/tex]
= [tex]\frac{4}{6}[/tex]
= [tex]\frac{2}{3}[/tex]
The outcomes that the product is 72: 6 and 12
So the probability is
= [tex]\frac{1}{C^{2} _{4} }[/tex]
= [tex]\frac{1}{6}[/tex]
Hence, the probability that the sum is greater than 12 is [tex]\frac{2}{3}[/tex]. The probability the product is 72 is [tex]\frac{1}{6}[/tex].

numbers is 5. Find the numbers.
9514 1404 393
Answer:
4, -1
Step-by-step explanation:
We can let x and y represent the two numbers. The first relation is ...
2x + 4y = 4
The second relation is ...
x - y = 5
Subtracting the second relation from half the first gives ...
1/2(2x +4y) -(x -y) = 1/2(4) -(5)
3y = -3
y = -1
From the second relation, ...
x = 5 +y = 5 -1 = 4
The two numbers are 4 and -1.

Step-by-step explanation:
At x=0, this function's y-value is simply 10. At x=2, the y-value is 28.
We can figure this out by using the slope formula.
[tex](y^2-y^1)/(x^2-x^1)[/tex]
We plug in values to get:

Step-by-step explanation:
3/5 == 0.6
Which part of the line is 0.6?
A < 0.5 so there's no way A can be the answer.
C > .75 so it can't be the answer either.
D > 1.5 so it can't be the answer either.
B is the only answer left and it sits just right in front of 0.5, which is close to 0.6.

What quadrant does Cos A < 0, Tan A < 0
Answer:
Cos A < 0 in the 3rd and 4th quadrants
Tan A < 0 in the 2nd and 4th quadrants
Step-by-step explanation:
In trigonometry, we make use of the ACTS initials to get which quadrant has it's sine, cosine or tangent functions as negative or positive.
In quadrant 1, it is denoted by A meaning All of sine, cosine and tangent functions are positive
In quadrant 2, it is denoted by C to mean that only cosine is positive i.e. greater than 0.
In quadrant 3,it is denoted by T to mean that only cosine is positive i.e. greater than 0.
In quadrant 4, it is denoted by S to mean that only sine is positive i.e. greater than 0.
Thus, comparing all above with the question, we can say that;
Cos A < 0 in the 3rd and 4th quadrants
Tan A < 0 in the 2nd and 4th quadrants
tan0 + 1=0
write your answer in radians in terms of pi
Answer:
Our range is within [0,2π]
We cant exceed that.
tan∆ + 1=0
tan∆= -1
∆=tan-¹(-1)
∆=-45°
Now it has 3 Solutions within the given interval
-45° x π/180 = -π/4
So For the second quadrant... 180-∆ = 180-45 =135°
It is true for tan(135) Which is also equal to -1
135xπ/180 = 3π/4
then
360-45 = 315
This is also true because tan(315)=-1
315° x π/180 = 7π/4
This is where we stop so we dont exceed the given range.
What is the point-slope form of a line with slope-5 that contains the point
(2, -1)?
Answer:
point slope form
y-y1=m(x-x1) where
m=slope and you are given a point (x1,y1)
slope=-5
point is (2,-1)
x1=2
y1=-1
m=-5
so
y-(-1)=-5(x-2)
y+1=-5(x-2) is answer
Which equation shows that the Pythagorean identity is true for 0 = 360°?
Select the equation that is in the form sin20 + cos20 = 1.
A. (-1)² +02 = 1
B. 02 + 12 =1
O c. 12 + 02 = 1
D. 02 + (−1)2 = 1
If the measure of an angle is 360°, then the value of sin²θ + cos²θ = 1 will be 0² + 1² = 1. Then the correct option is B.
What is a Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|² = |AB|² + |BC|²
where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).
The equation is given below.
sin²θ + cos²θ = 1
If the angle is 360°. Then the equation will be
sin²360° + cos²360° = 1
0² + 1² = 1
Then the correct equation is B.

write the quadratic formula y=x^2-6x+7 in vertex form.
Answer:
Step-by-step explanation:
Start like this: x^2 - 6x = -7. Now you have the x terms on one side and the constant on the other. Take half the linear term (-6x) which is 3 and then square that (9) and add it to both sides, giving you x^2 - 6x + 9 = -7+ 9, or x^2 - 6x + 9 = 2. Now make the left side into the perfect square binomial you created by completing the square: (x-3)^2 = 2, and then move the 2 over to get: (x-3)^2 - 2. That's the vertex form for a parabola with a vertex at (3, -2)
