Answer:
D. The number will be less than 1 because when adding the exponents,
11 + (-14) = -3, and a number in scientific notation with a negative exponent is less than 1.
Step-by-step explanation:
The question lacks appropriate option. Find the options below;
A. The value will be greater than 1 because 4.296 x 10^11 is a very large number and multiplication always increases the size of a number.
B. The value will be greater than 1 because 4 x 2 = 8 and 8 is larger than 1.
C. The value will be less than 1 because (4.296 x 10^11) x (1.8614 x 10^-14) will be a negative number. All negative numbers are less than one.
D. The number will be less than 1 because when adding the exponents,
11 + (-14) = 3, and a number in scientific notation with a negative exponent is less than 1.
Given the expression [tex](4.296*10^{11})(1.8614*10^{-14})[/tex], to expand the expression we will apply some of the law of indices below. If a, b and m are integers
[tex]a^m*a^n = a^{a+m}[/tex]
[tex]= (4.296*10^{11})(1.8614*10^{-14})\\\\= (4.296*1.8614)(10^{11}*10^{-14}) \\\\= 7.9965744 * 10^{11}*10^{-14}\\sum \ up \ the\ power\ of\ the \ exponents\\\\= 7.9965744 *10^{11-14}\\\\= 7.9965744 *10^{-3}\\[/tex]
= 0.0079965744
Based on the result, it can be seen that the resulting value is less than 1 due to the negative power of its exponent (i.e -3). Any scientific notation having a negative exponent always returns a value that is less than 1.
Answer:
The number will be less than 1 because when adding the exponents, 11 + (negative 14) = negative 3, and a number in scientific notation with a negative exponent is less than 1.

A water tank is 1•2m square and 1•35m deep. It is half full of water. How many times can a 9-litre bucket be filled from the tank
Answer:
180
Step-by-step explanation:
Volume = base * height(depth)
V=1.2*1.35=1.62 m³
1 m³=1000 liter
1.62*1000=1620 liter
1620/9=180 ( 9 liter bucket)
Grandma Susette is making a quilt. If the area of the
quilt is 24 3/5 square feet and one side has a length of
4 1/10,what is the width of the quilt?
Answer:
width = 6 ft
Step-by-step explanation:
let A = 24 3/5 = (24*5 +3)/5 = 123/5 ft^2 the area
l = 4 1/10 = (4*10 + 1)/10 = 41/10 ft the length
w = the width, w>0
since the area = length*width we have:
l*w = A
(41/10)*w = 123/5
by solving we find:
w = 6 ft
Answer each question.
1. Determine the type of graph for each function.
a. f(x) = 3x + 1
b. f(x) = x - 6x + 5
c. f(x) = 4x - x + 1
Need help with these Linear or Quadratic functions
Answer:
A: Linear
B: Linear
C: Linear
Step-by-step explanation:
So we have three functions:
[tex]f(x)=3x+1\\f(x)=x-6x+5\\f(x)=4x-x+1[/tex]
To determine the type of graph for each function, simplify each of them and then we can determine whether it's linear or quadratic.
1)
We have:
[tex]f(x)=3x+1[/tex]
This has a degree of 1. Quadratics have a degree of 2. In other words, quadratics have a x^2 term. There isn't one here, so this is a linear equation.
2)
We have:
[tex]f(x)=x-6x+5[/tex]
Simplify:
[tex]f(x)=-5x+5[/tex]
Again, this is of degree 1. There is no x^2 term. Thus, this is also a linear equation.
3)
We have:
[tex]f(x)=4x-x+1[/tex]
Simplify:
[tex]f(x)=3x+1[/tex]
This has a degree of 1. There is no x^2 term. Thus, this is also a linear equation.
Answer:
Step-by-step explanation:
a- f(x)=3x+1 it is linear equation
b: f(x)=x-6x+5
f(x)=-5x+5 linear equation
c: f(x)=4x-x+1
f(x)=3x+1 (linear equation)
(if there is no exponent then the graph is linear)

Akira receives a prize at a science fair for having the most informative project. Her trophy is in the shape of a
square pyramid and is covered in shiny gold foil.
3 in
How much gold foil did it take to cover the trophy, including the bottom?
inches
Do 4 problems Oo oo
Check
This question is Incomplete because it lacks the appropriate diagram for the square pyramid. Please kindly find attached the required diagram
Answer:
45 square inches
Step-by-step explanation:
From the question, we are told that the foil covers the body of the trophy including the bottom, hence the formula we would be applying =
Total Surface Area of the Square pyramid = 2bs + b²
Where s = Height of the square pyramid
b = Edge length of the square pyramid
From the attached diagram, we can see that:
s = 6 inches
b = 3 inches
Total Surface Area of the Square pyramid = 2bs + b²
= 2 × 3 × 6 + 3²
= 36 + 9
= 45 square inches.
Therefore, the amount of gold foil it took to cover the trophy, including the bottom is 45 square inches
Uma urna contém 10 bolas brancas,5 vermelhas e 4 pretas,todas iguais e indistinguiveis ao tato . Retirando-se uma bola ao acaso ,qual a probabilidade de ela não ser preta?
Answer:
15/19
Step-by-step explanation:
Nesta pergunta, queremos calcular a probabilidade de que uma bola retirada da urna não seja preta.
Existem três cores, uma vez que a bola removida não é preta, então é uma das outras duas cores.
Isso significa que a bola é branca ou vermelha. Observe que a probabilidade de a bola não ser preta é 1 menos a probabilidade de a bola ser preta Vamos descobrir a probabilidade de que a bola seja preta;
Matematicamente, isso seria;
número de bolas pretas / número total de bolas.
O número total de bolas é; 10 + 5 + 4 = 19 número de bolas pretas = 4
A probabilidade de a bola ser preta é de 4/19
Portanto, a probabilidade de que a bola não seja uma bola preta é
1 - 4/19 = 15/19

Answer:
See below
Step-by-step explanation:
Q1. if a counting number is selected at random from a set of whole number less than or equal to 20 find the probability of getting:
Counting numbers are Natural numbers: [tex]\mathbb{N}[/tex]
Also, we have Whole numbers. Despite not having an official symbol, I usually denote the set as [tex]\mathbb{Z}_{\ge 0}[/tex]
Whole numbers less than or equal to 20: [tex]A\leq 20, A \subset \mathbb{Z}_{\ge 0} \\\implies A=\{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20\}[/tex]
A. Prime numbers
From the set A, the prime numbers are 2, 3, 5, 7, 11, 13, 17, 19.
Once we have 21 numbers in total and 8 prime numbers, the probability is:
[tex]$P=\frac{8}{21} \approx 40\%$[/tex]
B. Composite numbers
From the set A, the composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20.
Once we have 21 numbers in total and 11 composite numbers, the probability is:
[tex]$P=\frac{11}{21} \approx 52\%$[/tex]
C. Divisible by three
From the set A, the numbers divisible by three are 3, 6, 9, 12, 15, 18.
Once we have 21 numbers in total and 6 numbers divisible by three, the probability is:
[tex]$P=\frac{6}{21} \approx 30\%$[/tex]
D. Square of 2
From the set A, the numbers square of 2 are 0, 1, 4, 9, 16.
[tex]\sqrt{0} =0[/tex]
[tex]\sqrt{1} =1[/tex]
[tex]\sqrt{4} =2[/tex]
[tex]\sqrt{9} =3[/tex]
[tex]\sqrt{16} =4[/tex]
Once we have 21 numbers in total and 5 numbers square of 2 , the probability is:
[tex]$P=\frac{5}{21} \approx 24\%$[/tex]
Q2. The opposite angle of acyclic quadrilaterals is in the ratio of 2:3. Find the degree measure of each opposite angle?
Once they're opposite, they add up to 180º
[tex]2x+3x=180 \implies 5x=180 \implies x=36[/tex]
The first angle is 72º
The second angle is 108º
Q3. what is the solution set of 9x-4<13x-7 (domain, x e z) ?
[tex]x \in \mathbb{Z}\\[/tex]
[tex]$x>\frac{3}{4} $[/tex]
[tex]$x\in \left(\frac{3}{4},\infty \right)$[/tex]
Q4. if three fourth of a number is one tenths, what is the number?
[tex]$\frac{3}{4} x =\frac{1}{10} \implies 3x=\frac{4}{10} \implies \boxed{x = \frac{2}{15}} $[/tex]
Q5. which one is the equation of the line passing through the origin and having a slope 4?
[tex]y=mx+b[/tex]
[tex]m: \text{slope}[/tex]
[tex]b: \text{y-intercept}[/tex]

Suppose you see a lightning flash and hear a thunder clap exactly 10 seconds later. The speed of sound is 1080 feet per second and there are 5280 feet in a mile. Estimate, to the nearest half mile, how many miles you are from the lightning flash. Assume the speed of light is infinite.
Answer:
[tex]\approx 2\ miles[/tex]
Step-by-step explanation:
Difference of 10 seconds between the lightning flash and its thunder clap.
Given that the speed of light is infinite.
So, lightning will be seen at the same time it happens.
10 seconds is the time taken by the sound to reach to the person.
Time taken = 10 seconds
Speed of sound = 1080 ft/sec
To find:
Distance from lightning flash in miles.
Solution:
First of all, let us a have a look at the formula:
[tex]Distance = Speed \times Time[/tex]
Putting the given values:
Distance = [tex]1080\times 10 = 108000\ feet[/tex]
5280 feet = 1 mile
1 feet = [tex]\frac{1}{5280}[/tex] miles
10800 feet = [tex]\frac{1}{5280}\times 10800 \approx 2\ miles[/tex]
12. Michelle is selling her condo. She needs to make at least $42,000 from the sale so she can
make a down payment on a new house. If a 5.5% real estate commission is deducted, what is
the lowest offer Michelle should accept to get her down payment?
Answer:
Total amount she need = $44,444
Step-by-step explanation:
Given:
Amount Michelle needs = $42,000
Real state commission = 5.5%
Find:
Total amount she need
Computation:
Assume,
Total amount she need = x
So,
Real state commission = 0.055x
So,
x - 0.055x = 42000
x (0.945) = 42,000
x = 44,444 (Approx)
Total amount she need = $44,444

Find the coordinates of the midpoint M and the distance between J(4,3) and K(2,-3)
Answer:
(3,0)
Step-by-step explanation:
Co-ordinates of J =(4,3)
Co-ordinates of K = (2,-3)
Midpoint formula :
= [tex]\frac{x_{1}+x_{2} }{2} , \frac{y_{1} +y_{2} }{2} \\ \frac{4+2}{2} ,\frac{3+(-3)}{2}\\\frac{6}{2},\frac{3-3}{2}\\3, 0[/tex]
Coordinates of the midpoint M (3,0)
The coordinates of the midpoint M is (3,0) and the distance between J(4,3) and K(2,-3) is 6.32 units.
What is distance formula?The distance between two points of the xy-plane can be found using the distance formula. The distance formula is:
√[(x₂ - x₁)² + (y₂ - y₁)²].
Now given coordinates of two points are,
J(4,3) and K(2,-3)
Therefore we have,
x₁ = 4
y₁ = 3
x₂ = 2
y₂ = -3
To find the midpoint between J and K we have,
{[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}
Put the values, we get
{[(4+2)/2] , [(3+(-3)/2]}
solving them,
{(6/2) ,(0/2)}
or,
(3,0)
which is the required midpoint M.
Now distance between J(4,3) and K(2,-3) = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(2 - 4)² + (-3 - 3)²]
= √[(- 2)² + (-6)²]
= √4 +36
= √40
= 6.32 units
Thus, the coordinates of the midpoint M is (3,0) and the distance between J(4,3) and K(2,-3) is 6.32 units.
