Lucinda is saving money for a hot-air balloon trip to celebrate her graduation. She needs $300 dollars. Express this amount as an integer. Is this represented by a negative number or a positive number?
Answer:
Positive number
Step-by-step explanation:
Given that:
Lucinda is saving money for a hot-air balloon trip to celebrate her graduation and she needs $300 dollars.
Let x be the amount of her savings and she needs $300
SO;
x + 300 = 0
As an integer, it is represented by a positive number because she needs this amount of money in addition to what she already saved.
Find the diagonal of the box using the Pythagorean Theorem.
Answer:
26 cm
Step-by-step explanation:
Given:
Length = 24 cm
Width = 8 cm
Height = 6 cm
Required:
Diagonal of the box
SOLUTION:
Using the pythagorean theorem, [tex] a^2 + b^2 + c^2 = d^2 [/tex], where,
a, b and c are the dimensions of the box, and d is the length of the diagonal.
Plug in the value into the formula
[tex] 24^2 + 8^2 + 6^2 = d^2 [/tex]
[tex] 676 = d^2 [/tex]
[tex] \sqrt{676} = \sqrt{d^2} [/tex]
[tex] 26 = d [/tex]
Length of diagonal of the box = 26 cm

Finding the Volume of a Rectangular Pyramid
Your overall formula for finding the volume of these multi-faceted shapes is V = (l x w x h) / 3. Basically, your first step is finding the area of the base by multiplying length by width. Once you determine the area of the base, multiply that by the height.

Mikah and Gracie were running laps at the local gym. Mikah ran 1 and 4/8 laps, and Gracie ran 1 and 1/2 laps. Who ran a further distance?
Answer:
Trick question they both ran equal distance
Step-by-step explanation:
Gracies distand 1 and 1/2 is already in simplist form, but Mikahs distance 1 and 4/8 can be reduced.
More specifically the fration 4/8 can be reduced, finding the largest common multiple between 4 and 8 we find that 4 is the largest number that goes into both.
This results in the simplification of 1 and 4/8 to 1 and 1/2 which is the same as Gracies distance.

In a group of students, 50% of the students were taking statistics subject, 30% economics and 10% both the subjects. What is the probability that a student was taking neither statistics nor
economics?
a) 30% b) 90%
c) 70% d) None of these
Solution with som explanation
Answer:
a) 30%
Step-by-step explanation:
50% of the students were taking statistics subject, 30% economics and 10% both the subjects.
The probability a student takes only statistics = 50% - 10% = 40%
The probability a student takes only economics = 30% - 10% = 20%
The probability a student was taking neither statistics nor economics = 100% - (40% + 20% + 10%)
The probability a student was taking neither statistics nor economics = 30%

Hope it will help you......A kite of area 40 m squarehas one diagonal 2 m longer than the other. Find the length of the diagonal
Answer:
Length of diagonal 1: 8 metersLength of diagonal 2: 10 metersStep-by-step explanation:
Let d1 be the first diagonal and d2 be the second diagonal.
Given
Area = 40 square meters
And one diagonal is 2 meter longer than other
[tex]d_2 = d_1+2[/tex]
The formula for area of kite is;
[tex]Area = \frac{1}{2} * d_1 * d_2[/tex]
Putting the known values
[tex]40 = \frac{1}{2} * d_1 * (d_1+2)\\80 = (d_1)^2+2d_1\\d_1^2 +2d_1-80 = 0\\[/tex]
The expression is a quadratic polynomial
Factorizing
[tex]d_1^2 + 10d_1-8d_1-80 = 0\\d_1(d_1+10)-8(d_1+10) = 0\\(d_1+10)(d_1-8) = 0\\d_1 + 10 = 0\\d_1 = -10\\d_1-8 = 0\\d_1 = 8[/tex]
As the value of length cannot be negative so discarding the negative value
[tex]d_1 = 8d_2 = d_1+2 = 8+2 =10[/tex]
Hence,

Jane is studying the weather in Alaska. She has recorded the temperature for four days in January, in degrees Fahrenheit, as shown in the table.
I have attached an image of the complete question.
Answer:
Options A & F are correct
Step-by-step explanation:
From the image attached, we have the following recorded temperature for 4 days in January.
Monday: -5° F
Tuesday: -1° F
Wednesday: 3° F
Thursday: 5° F
Option A is correct because the temperature on Monday and Tuesday is negative and thus below zero.
Option B is not correct because the temperature on Monday and Thursday are not the same since they are -5° F and 5° F respectively
Option C is not correct because the temperature on all days was not above zero since on Monday and Tuesday had negative temperatures
Option D is not correct because the lowest temperature below zero is on Monday and not Thursday
Option E is not correct because the temperature on Wednesday and Thursday are positive and not below zero.
Option F is correct because Monday had a temperature of -5° F which is the lowest gotten below zero
The temperature on Monday and Tuesday is negative and thus below zero.
The temperature on Monday had a temperature -5F which is the lowest value below zero.
