Answer:
a. 85.5 sq ft
b. 3 bottles
Step-by-step explanation:
a. The cardboard is rectangular in shape. How much he needs to paint is the same as the cardboard that he needs to paint.
The area of a rectangle is given as:
A = L * B
where L = length and B = breadth
Therefore, the area of the cardboard having dimensions 14 1/4 feet by 6 feet is:
A = 14 1/4 * 6
A = 57 / 4 * 6 = 85.5 sq feet
He needs to paint 85.5 sq feet of the cardboard.
b. On bottle of paint covers 40 sq feet. The number of bottles he will need for his backdrop will be the area he needs to paint divided by the amount of paint that can cover 40 sq feet:
85.5 / 40 = 2.14
Since the number of bottles he will need is a whole number and its greater than 2, then it must be 3.
To paint the entire cardboard, he must have 3 bottles of paint.
Answer:
75 feet

Solve the equation -10X +1 + 7X = 37
Answer:
X = -12
Step-by-step explanation:
-10X + 1 +7X = 37
-10X + 7X + 1 = 37 {Add the like terms}
-3X + 1 = 37 {Subtract 1 form both sides}
-3X + 1 -1 = 37 -1
-3X = 36 {Divide both sides by (-3)}

Answer:
False --> 1011 > 1100
True --> 110 + 111 == 1101
50 --> 1010 x 101
13 --> 110 + 111
17 --> 1010101 / 101
Step-by-step explanation:
This solution is achieved by calculating the binary operations, then finding either their values or the validity of their statements.
1011 > 1100 is the same as 11 > 12, which is false.
110 + 111 == 1101 is the same as 6 + 7 = 13, which is true.
1010 x 101 is the same as 10 x 5, which is 50.
110 + 111 is the same as 6 + 7, which is 13.
1010101 / 101 is the same as 85 / 5, which is 17.
write 0.126126126... as a fraction
Answer:
x = 126/999
Step-by-step explanation:
Let x = .126126126 repeating
Multiply each side by 1000
1000x = 126.126126126 repeating
subtract the first equation from the second
1000x = 126.126126126 repeating
- x = .126126126 repeating
999x = 126
Divide each side by 999
999x/999 = 126/999
x = 126/999
Angle θ is in standard position and terminates in quadrant II. If tanθ = -15/8, then cscθ = _____.
Answer:
csc Θ = [tex]\frac{17}{15}[/tex]
Step-by-step explanation:
Given
tan Θ = - [tex]\frac{15}{8}[/tex] = [tex]\frac{opposite}{adjacent}[/tex] ← of a right triangle , then
hypotenuse h² = 15² + 8² = 225 + 64 = 289 ( square root both sides )
h = [tex]\sqrt{289}[/tex] = 17
Using the identity
csc x = [tex]\frac{1}{sinx}[/tex]
sin Θ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{15}{17}[/tex]
Since Θ is in second quadrant then sinΘ and csc Θ > 0, thus
csc Θ = [tex]\frac{1}{\frac{15}{17} }[/tex] = [tex]\frac{17}{15}[/tex]

a square and a triangle have equal perimeters. the square has a perimeter of 4(2p-4), and the triangle has a perimeter of 4p+36. find the perimeter value.
A. p= 72
B. p= 44
C. p= 88
D. p= 36
Answer:
C
Step-by-step explanation:
Since the figures have equal perimeters we can equate them, thus
4(2p - 4) = 4p + 36 ← distribute left side
8p - 16 = 4p + 36 ( subtract 4p from both sides )
4p - 16 = 36 ( add 16 to both sides )
4p = 52 ( divide both sides by 4 )
p = 13
Substitute p = 13 into either of the 2 expressions, then
4p + 36 = 4(13) + 36 = 52 + 38 = 88 → C
The value of perimeter is found as 88 units. The correct option is (C).
How to write a linear equation?A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.
As per the question the perimeters are equal.
The following equation can be written as,
4(2p - 4) = 4p + 36
⇒ 8p - 16 = 4p + 36
⇒ 4p = 52
⇒ p = 13
Thus, the perimeter value can be obtained by substituting p = 13 in 4p + 36 as below,
⇒ 4 × 13 + 36 = 88
Hence, the perimeter value is 88 units.

If an angle has a measure of 1 radian, then the arc intercepted by that angle has an arc length equal to the radius of the circle.
Answer: True
Step-by-step explanation: the angle subtends, s, divided by the radius of the circle, r. One radian is the central angle that subtends an arc length of one radius (s = r). Since all circles are similar, one radian is the same value for all circles.
The given statement is correct. If an angle has a measure of one radian, the arc intercepted by that angle has an arc length equal to the radius of the circle.
What is meant by radian and radius?Simply put, a Radian is a unit of measurement for angles that is based on the radius of a circle. This means that if we imagine wrapping the length of the radius around a circle, the angle formed at the center of the circle by this arc is equal to 1 Radian. Radians, like degrees, are a type of angle measurement. One radian is equal to the angle formed when the radius of the circle is equal to the arc opposite the angle. So, in the diagram above, the angle is one radian because the arc AB is the same length as the radius of the circle.Therefore,
Because the Latin word for length is spatium, arc lengths are denoted by s.
Length of an Arc = θ × r,
Where θ exists in radian.
Length of an Arc = θ × (π/180) × r,
Where θ exists in degree

Step-by-step explanation:
If you think money, a question like this won't confuse you.
Which would you rather owe your parents
13 dollars or
10 dollars
The answer is obvious, isn't it? Most people would rather owe 10 dollars rather than 13.
The minus sign is the same as debt. - 13 is less than - 10. You are further and further in the hole when you owe 13 dollars than 10.
So the inequality is not correct. The answer is no.
So still with money
-13<- 11
13 > 11
you would rather have 13 dollars in your pocket than 10.
You would rather owe -10 dollars than - 13

A set of sofa prices are normally distributed with a mean of 2500 dollars and a standard deviation of 200 dollars.
A leather sofa has a price of 2410 dollars.
What proportion of sofa prices are higher than the price of the leather sofa?
You may round your answer to four decimal places.
We have been given that a of sofa prices are normally distributed with a mean of 2500 dollars and a standard deviation of 200 dollars. A leather sofa has a price of 2410 dollars. We are asked to find the proportion of sofa prices that are higher than the price of the leather sofa.
First of all, we will find the z-score corresponding to sample score 2410.
[tex]z=\frac{x-\mu}{\sigma}[/tex]
[tex]z=\frac{2410-2500}{200}[/tex]
[tex]z=\frac{-90}{200}[/tex]
[tex]z=-0.45[/tex]
Now we need to find area under normal curve that is greater than z-score of [tex]-0.45[/tex] that is [tex]P(z>-0.45)[/tex].
Using formula [tex]P(z>a)=1-P(z<a)[/tex], we will get:
[tex]P(z>-0.45)=1-P(z<-0.45)[/tex]
Now we will find area under curve using normal distribution table.
[tex]P(z>-0.45)=1-0.32636[/tex]
[tex]P(z>-0.45)=0.67364[/tex]
Upon rounding to 4 decimal places, we will get:
[tex]P(z>-0.45)\approx 0.6736[/tex]
Therefore, approximately 0.6736 of sofa prices are higher than the price of the leather sofa.

Find the volume of a right circular cone that has a height of 4.5 ft and a base with a
diameter of 14.2 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
The volume of the cone is:
237.6 cubic feet.Step-by-step explanation:
The volume of a cone is:
Volume of a cone = (1/3) PI * r^2 * hWhere:
r = radius.
h = height.
Since the exercise provides the diameter but not the radius, you simply have to divide the diameter in two:
Radius = diameter / 2 Radius = 14.2 ft / 2 Radius = 7.1 ft / 2Now we proceed to replace in the formula:
Cone volume = (1/3) PI * (7.1 ft)^2 * 4.5 ft Cone volume = 237.5515285 ft^3 Cone volume = 237.6 ft^3QUICK ANSWER THIS!!!

Answer:
a) A triangle which the angles ratio is 1 : 2 : 3 is a 30º - 60º - 90º right triangle.
b) The shortest side is opposite to the shortest angle. So, we can calculate it using sin 30º.
[tex]$\text{sin}(30\º)=\frac{\text{Opposite side to x}}{19} $[/tex]
[tex]$\frac{1}{2} =\frac{\text{Opposite side to x}}{19} $[/tex]
[tex]$\text{Opposite side to x}= 9.5$[/tex]
Answer:
see explanation
Step-by-step explanation:
(a)
Sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide 180° ( sum of angles in a triangle ) by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio, thus
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Thus the triangle is right
-----------------------------------------
(b)
The sides of a 90°- 60°- 30° triangle are in the ratio
2 - [tex]\sqrt{3}[/tex] - 1 ( where 2 represents the hypotenuse )
Thus the other 2 sides of the triangle are
19 ÷ 2 = 9.5 , and
9.5 × [tex]\sqrt{3}[/tex] ≈ 16.45
The shortest side is 9.5
