Answer:
are you sure this is the right question? none of those have a sum of 23
Step-by-step explanation:
Answer:
900
Step-by-step explanation:
We assume that your 4-digit number must be in the range 1000 to 9999. Clearly, any number ending in zero will meet your requirement:
1000/100 = 10
3890/389 = 10
However, the requirement cannot be met when the 1s digit is other than zero.
__
For some 3-digit number N and some 1s digit x, the 4-digit number will be
4-digit number: 10N+x
Dividing this by N will give ...
(10N+x)/N = 10 remainder x
N will only be a factor of 10N+x when x=0.
So, there are 900 4-digit numbers that meet your requirement. They range from 1000 to 9990.

Answer:
16
Step-by-step explanation:
Angle Z is not the right angle, so the rays that make up the angle are ...
- hypotenuse ZX
- adjacent leg ZY
The length of the adjacent leg ZY is shown as 16.
Answer:
60 feet
Step-by-step explanation:
We know that a triangle has 3 sides, in this case we will call them a, b and c.
It tells us that everything is material, it measures 20, that is:
a + b + c = 20
They tell us that she wants to triple each side and to know how much material she would need in total. Then it would be:
border material need = 3 * a + 3 * b + 3 * c
common factor 3:
border material need = 3 * (a + b + c)
border material need = 3 * 20
border material need = 60
Which means that she needs a total of 60 feet of material.
Question:
a. A = (2πr)(r)
b. A = (2πr)(2r)
c. 
d. 
Answer:
The correct option is
Step-by-step explanation:
The formula for the area, A of a parallelogram = base, b × height, h
Therefore, since the base dimension is approximately half the perimeter of a circle, we have;
Base, b = 2·π·r × 1/2
Where the height of the parallelogram, as shown in the diagram is approximately the radius of the circle, we have;
Height, h = r
Therefore, the approximate area, A of the parallelogram is given by the following relation;
A = b × h = 2·π·r × 1/2 × r Which is the same as A = 
.
