Answer:
3, 9, and 10
Step-by-step explanation:
To figure out whether 4,320 is divisible by these numbers, we can use their divisibility rules to help us out.
A number is divisible by 3 or 9 if its digits add up to a number divisible by 3 or 9. The digits of 4,320 add to 4 + 3 + 2 + 0 = 9, which is divisible by both 3 and 9, so 4,320 is divisible by 3 and 9.
A number is divisible by 10 if its last digit is a 0, which we have here, so 4,320 is divisible by 10.

tan^2 70° -sec^2 70°
Answer:
-1
Step-by-step explanation:
We need to find the value of tan² 70° -sec² 70°.
We know that,
[tex]\sec^2\theta-\tan^2\theta=1[/tex] ...(1)
We can write the given expression as :
tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)
=-(sec² 70°-tan² 70°)
Using identity (1)
=-(1)
= -1
Hence, the value of the given expression is -1.

Andre says that 3 divided by 2/3 equals 4 and 1/3 because there are four groups of 2/3 and 1/3 left. Do you agree with Andre? Explain your reasoning.
Answer:
No I do not agree with Andre
Step-by-step explanation:
Andre says that 3 divided by 2/3
Solving for 3 ÷ 2/3
3 ÷ 2/3
= 3 × 3/2
= 9/2
= 4 1/2
Therefore, 3 divided by 2/3 is 4 1/2
Andre's reasoning is wrong.

At the start of Kerin's diet he weighed 13 stone 12 pounds. Three months later he weighed 12 stone 10 pounds. There are 14 pounds in a stone. Calculate the reduction in Kerins weight as a percentage of his inetial weight.
Beginning of diet, 13 stone 12 pounds
13(14) + 12 = 194
Three months later, 12 stone 10 pounds
12(14) + 10 = 178
He lost 16 pounds in 3 months
I'm not really sure what the percentage would be, but it might be 16%

Anna has a small business. Her mean revenue over the past 10 years is $85,000 with standard deviation of 2200. Anna earned 55% of her mean revenue by December 31, 2020. How much money does Anna want to have by year's end?
Answer:
$121,000
Step-by-step explanation:
Mean = $85000
Standard deviation = $2200
55% of mean revenue at the end of the year will be :
0.55 * $2200
0.55 * 2200
= $121,000
Hence, Anna wants to have $121,000 by year end

Answer:
Father's shadow is 9 feet long.
Step-by-step explanation:
From the given figure,
ΔABC and PQR will be similar.
So their corresponding sides will be proportional.
[tex]\frac{AC}{PR}=\frac{BC}{QR}[/tex]
[tex]\frac{AC}{7.5}=\frac{6}{5}[/tex]
AC = [tex]\frac{6\times 7.5}{5}[/tex]
AC = 9 feet
Therefore, measure of the father's shadow is 9 feet.
Eleanor Wotek took out a simple interest installment loan of $1,525 at 8 percent for 6 months. Her monthly payment on the loan is $260.17. After 3 payments, the balance is $769.98. If she pays off the loan when the next payment is due? a. What is the final payment? (2 points) b. How much is saved by paying off the loan early? (3 points)
Answer:
a. Final payment = $831.58
b. Amount saved = -$520.34
Step-by-step explanation:
a. What is the final payment? (2 points)
Interest element of fourth month payment = Principal balance after third month payment * 8% = $769.98 * 8% = $61.60
Final payment = Principal balance after third month payment + Interest element of fourth month payment = $769.98 + $61.60 = $831.58
b. How much is saved by paying off the loan early? (3 points)
Amount saved = (Monthly payment * 2 months) - Final payment = ($260.17 * 2) - $831.58 = -$520.34
Note:
The amount saved in part b above is negative i.e. -$520.34 which implies that Eleanor Wotek actually paid more instead of saving some amount.
Consider the equation and the following ordered pairs: (−4,y) and (x,2).
y=2x+8
Step 1 of 2 : Compute the missing x and y values so that each ordered pair will satisfy the given equation.

Complete the table below.

row 1−4 Answer
row 2 Answer
2
Answer:
(-4, 0) and (-3, 2)
Step-by-step explanation:
Substitute each value into the equation.
Since x = -4 in the first ordered pair, to find y, you just put it into the equation as x:
y = 2(-4) + 8
y = -8 + 8
y = 0
The first ordered pair is (-4, 0)
Now, do the same for the second ordered pair. Substitute 2 for the y and solve for x:
2 = 2x + 8
-6 = 2x
x = -3
The second ordered pair is (-3, 2)
I hope this helps!
The missing coordinates in the ordered pairs are (-4, 0) and (-3, 2).
What are ordered pairs?An ordered pair (x, y) is used to represent the location of a point in coordinate geometry where x is the horizontal distance and y is the vertical distance of the point.
Given that, a line y = 2x+8, passes through two points (-4, y) and (x, 2) we need to find the value of x and y,
Since, the line is passing through the points therefore, the points will satisfy the equation of the line,
Put x = -4, in the equation,
y = 2(-4)+8
y = 0
So, the point is (-4, 0)
Put y = 2, in the equation,
2 = 2x+8
2x = -6
x = -3
So, the point is (-3, 2)
Hence, the missing coordinates in the ordered pairs are (-4, 0) and (-3, 2).

Which figure represents the image of parallelogram
LMNP after a reflection across the line y = x?
o figure A
O figure B
o figure C
O figure D
The figure that represents the image of parallelogram LMNP after a reflection across the line y = x is figure C
How to determine the figure?From the graph, the coordinates of the parallelogram LMNP are:
L = (3,1)
M = (4,3)
N = (5,3)
P = (4,1)
When reflected across the line y = x, the coordinates become
L' = (1,3)
M = (3,4)
N = (3, 5)
P = (1, 4)
The figure with the above coordinates is figure C
Hence, the figure that represents the image of parallelogram LMNP after a reflection across the line y = x is figure C
