Maya says there are 4 hundreds in 5,467. Jenny says there are 54 hundreds in 5,467 they're both right.
Answer:
Both are right
Step-by-step explanation:
As maya say 4 hundreds in 5,467
this is right because the place value of 4 in 5467 is 4 hundreds = 400.
but Jenny says 54 hundreds in 5,467
this also correct because number 5467 in word is five thousand four hundred and sixty seven
54 hundreds = 54 × 100 = 5400
as here place value of 5 is 5000 and place value of 4 is 400
so, Addition of both gives = 5000 + 400 = 5400
If we divide 5400 by 100, we would have 54
It shows that there are 54 hundreds
so, Both are right

There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?
PLZ answer fast its an emergancy
Answer:
5/11*5/11=25/121
Step-by-step explanation:
There are 6+5 marbles.
Of those, 5 are red.
The chances of drawing a red marble are 5/11
Since you replace the marble you drew, the chances each draw remain 5/11
You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11. The odds of that also being red are 5/11… but we only care about that 5/11ths the time
how do I decease 7 by 3%
Answer:
6.79
Step-by-step explanation:
First of all, you will have to know how much is 3% of 7 in order to decrease it by that amount.
7 x 0.03 = 0.21
Now that you know the amount, you can subtract it from seven and therefore you have decreased 7 by 3%.
7 - 0.21 = 6.79
Answer:
Percentage decrease = 7 × 3%
7 - Percentage decrease = 7-(3% x 7)= 7 - 3% x 7=7 x (1 - 3%)= (100% - 3%) × 7 = 97% x 7 = 679%

Camila drew a triangle with a side that is 24
inches long and a side that is 18 inches long.
Which of the following could be the length of the
third side of the triangle that Camila drew? Select
THREE that apply.
42 inches
40 inches
18 inches
7 inches
6 inches
5 inches
Answer:
Step-by-step explanation:
It’s going to be 42 inches and 40 inches because we are simplifying
The solution is, 40 inches ,or, 7 inches ,or, 18 inches, could be the length of the third side of the triangle that Camila drew.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Here, we have,
given that,
Camila drew a triangle with a side that is 24 inches long
and a side that is 18 inches long.
we know, that,
sum of length of two sides > third side,
so, the possible lengths are,
40 inches , 7 inches , 18 inches
Hence, The solution is, 40 inches ,or, 7 inches ,or, 18 inches, could be the length of the third side of the triangle that Camila drew.

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that a store receives 8 boxes of Picture frames to sell. Unfortunately, 3 of the frames are broken and cannot be sold. There are 45 left that can be sold.
Assume that the number of frames in each box are [x]. Then, we can write -
8x = 45 + 3
8x = 48
x = 6
Therefore, there are 6 frames in each box.

If f(0) = 2 sin 0 - cos 20, find f(pi/6)
Answer: 1/2
Step-by-step explanation:
f(Ф) = 2sin(Ф) - cos(2Ф)
f(pi/6) = 2sin(pi/6) - cos(pi/3)
Use the pi circle or a calculator
f(pi/6) = 2(1/2) - 1/2 = 1/2

A line of best fit predicts that when x equals 29, y will equal 32.75, but y actually equals 32. What is the residual in this case
Answer:
The residual is 0.75
Step-by-step explanation:
Recall that the residual is the VERTICAL distance between the y-value of the data point and the y-value of the predicted line. This distance can be calculated using the absolute value of the difference between these y-values.
Therefore, in our case the residual is: |32 - 32.75| = |-0.75| = 0.75

how many different ways could first, second, and third place finishers occur in a race with six runners competing?
Answer:
720
Step-by-step explanation:
This is a permutation since the order at which the people are picked matter due to the fact that it is a race. Using the permutation formula
P= n!/ (n-r)! you can find the different ways the race would end. n stands for the total number of objects in the set while r stands for the number of objects chosen from said set. Then you plug in the numbers in the formula: P= 10!/(10-3)!= 720
A bond has a $1,000 par value, nine years to maturity, and pays a coupon of 5.25% per year, semiannually. The bond is callable in three years at 115% of its par value. If the bond’s yield to maturity is 5.32% per year, what is its yield to call?
Please show work. Or explain how to get answer through the calculator.
A) 9.08%
B) 9.24%
C) 9.86%
D) 9.62%
E) 8.96%
Answer:
C) 9.86%
Step-by-step explanation:
Given that:
Par value of the bond = $1000
Coupon rate = 5.25%
Years of maturity = 9
years to call = 3
price to call = 115% * 1000 = 1150
YTM of the bond = 0.0532
Using Excel formula:
The current price of the bond = P-V(0.0532/2, 9*2, 0.0525*1000/2, 1000)
= $995.04
The yield to call = 2 * RATE( 3*2, 0.0525*1000/2, 995.04, 1150)
The yield to calll = 9.86%
