What is fraction?
Fractions represent parts of a whole. In mathematics, fractions are represented as numbers that define part of a whole. A fraction can be a part or subset of any quantity of a whole, and a whole can be any number, value, or thing.
All fractions consist of a numerator and a denominator, separated by horizontal bars called fraction bars.
The denominator indicates the number of parts into which the whole is divided. Placed at the bottom of the break below the break bar. The
counter indicates how many sections of the fraction are displayed or selected. Placed at the top of the break above the break bar.
As we know ,
one hundredth is 1/100
one thosandth is 1/1000
But now , 10 × 1/1000 = 1/100
This means that there are 10 thousandths in one hundredth.
Hence, ten thousandths are in one hundredth.

Answer:
The measure of angle 1=52
The measure of angle 2=58
The measure of angle 3=31
Step-by-step explanation:
The measure of angle 1 is 52 because the angle out of the triangle is 128. The measure of angle 1 plus 128 equals 180. Using this info you could do 180-128, which equals 52. The measure of angle 1 equals 52.
The measure of angle 2 is 58 because I already know 2 of the values of the triangle, in which Angle 2 is also in. One triangle adds up to 180. The values of the other 2 angles are 52 and 70. Using this information I can use the equation 52+70+x=180, which you then simplify to 122+x=180. X equals 58. The measure of angle 2 equals 58
The measure of angle 3 is 31 because the angle out of the triangle is 70. The missing angle plus 70 equals 180. Using this info I could do 180-70. The missing angle is 110. There is already one given angle, and I have figured out the other, using this info I can now finally find the measure of angle 3. I can find this out by using the equation 110+39+x=180. You would then simplify the equation to 149+x=180. X equals 31. The measure of angle 3 equals 31.

what is the linear equation
The linear equation of the given points (2, -2) and (0, -1) is y = (-1/2)x - 1
The first point = (2, -2)
The second point = (0, -1)
The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the values in the equation
The slope of the line m = (-1 - -2) / (0 - 2)
= -1+2 / -2
= 1 / -2
= - 1/2
The slope intercept form is
y = mx + b
Where m is the slope of the line
b is the y intercept
The point slope form is
[tex]y-y_1=m(x-x_1)[/tex]
Substitute the values in the equation
y - -2 = (-1/2) (x-2)
y + 2 = -1/2 x + 1
y = (-1/2)x + 1 -2
y = (-1/2)x - 1
Hence, the linear equation of the given points (2, -2) and (0, -1) is y = (-1/2)x - 1

Data generated from a sample of 49 apples randomly selected from a shipment indicated a mean weight of 122. 5 grams per apple. Calculate and interpret a 95% confidence interval for the mean weight per apple.
The 95% confidence interval for the average apple weight is (119.14, 125.86).
An apple typically weighs 120 grams with a 12-gram standard deviation, according to one manufacturer. The average weight of an apple was 122. 5 grams, according to statistics created from a sample of 49 apples that were randomly chosen from a shipment.
Let, n = 49
x = 122.5
σ = 12
To calculate and interpret a 95% confidence interval for the average apple weight, use the formula;
⇒ (x ± 1.96*σ/√n)
⇒ (122.5 ± 1.96*12/√49)
⇒ (119.14, 125.86)

The simplified value of (3.7 x 10^-9) - (8.2 x 10^-8) in scientific notation is - 7.83 x 10^-8. Option A is correct.
We will solve the given expression using laws of exponents.
Some laws of exponents are:
(a²) · (a³) = a²⁺³ = a⁵(a²)³ = a²ˣ³ = a⁶(a²) ÷ (a³) = a²⁻³ = a⁻¹a⁻¹ = 1 / aWe are given:
(3.7 x 10^-9) - (8.2 x 10^-8)
= (3.7 x 10^(-1 -9)) - (8.2 x 10^-8)
= (3.7 x 10^-1 x 10^-8) - (8.2 x 10^-8)
= (0.37 x 10^-8) - (8.2 x 10^-8)
= (0.37 - 8.2) x 10^-8
= - 7.83 x 10^-8
So, the simplified value of (3.7 x 10^-9) - (8.2 x 10^-8) is - 7.83 x 10^-8.

Given,
sin u=3/5, 0 < u < pi/2
tan u= 1/2, pi < u < 3pi/2
We need to find sin 2u, cos 2u, and tan 2u
sin2u=2sinucosu

1/2=3/5/cosu
cosu=3/5×2
cosu=6/5
So sin2u=2(3/5)(6/5)
sin2u=36/25
cos2u=1-2sin²u
=1-2(36/25)²

cos2u=-3.142
tan2u=sin2u/cos2u
Substitute the values of sin2u and cos2u
sin2u=36/25/(-3.142)

I really need help on how to solve this!
Answer:
a] 5 dogs
b] 16 dogs
Step-by-step explanation:
The minimum number of dogs that could have a mass of more than 26 kg is 5. This is because dogs with a mass of 30 ≤ x ≤ 40 have a frequency of 5. The dogs in the 20 ≤ x ≤ 30 range could be more than 26 kg, but they could also be less than 26 kg, so these are not included in the minimum.
The maximum number of dogs that could have a mass of 26 kg is 16 because both dogs in the 30 ≤ x ≤ 40 range (5) and 20 ≤ x ≤ 30 range (11) could weigh more than 26 kg. 11 + 5 = 16, giving us our answer for the maximum.

Fatima paid for 5 pallets of grass to be delivered. Each pallet of grass cost $129. 95. Fatima paid $76. 20 for delivery. What is the total amount fatima paid?.
Fatima paid $129.95 for pallet of grass cost and $ 76.20 for delivery. The total amount Fatima paid is $725.95.
Pallet Grass Cost: The quality and type of grass you want will impact the overall cost of sod. Most homeowners pay between $150 and $450 per pallet of sod for their yards or an average of $300. When it comes to square footage, sod costs between $0.35 and $0.85, or an average of $0.60 per square foot.
Given in the question:
Number of Pallets = 5
Cost of each pallet = $129.95
Total amount spend on Pallets
= Number of Pallets × Cost of each pallet
= 5 × $129.95 = $ 649.75
Also given;
Amount spend on Delivery = $76.20
Total Amount Paid by Fatima
= Total amount spend on Pallets + Amount spend on Delivery

the dimensions of col a and nul a add up to the number of columns in a.
a. true
b. false
Using Rank theorem , the dimensions of col A and Null A add up to the number of colmns in A. It is true statement.
The rank of matrix A denoted as rank(A) is the dimension of the column space Col(A).
The nullity of matrix A written as nullity(A) is the dimension of the null space Nul(A)
Rank Theorem:
If A is a matrix with n columns, then
Rank (A) + nullity (A) = n
In other words we can say that
dim (Col(A) ) in column space + dim (Nul(A)) in empty space = total number of columns in A
The rank theorem is really important theorem.
It is gives a strong relationship between the Null space ( all possible vector x such that Ax = 0) and the column space (the set of vectors b matching Ax=b) explain the two main objectives. The more freedom we have for choosing x, the less freedom we have for choosing b, and vice versa.
